    snow vehicle
    The invention relates to a snow vehicle according to the preambles of claims 1 and 2.
    A snow vehicle or snowmobile is a means of transportation on ice, permafrost and snow.
    Snowmobiles (snowmobiles or snowmobiles) are often used as a means of transport in ski areas and have runners on the front for steering. The engine power is transmitted to an centrally located drive caterpillar via an automatic and centrifugal clutch.
    A snow vehicle, however, only has chains and is controlled or steered by the chains. The crawler tracks are arranged on both sides along the longitudinal axis of the vehicle frame and can be driven independently of one another. Sometimes it is possible that the chain drives are even driven in opposite directions, which allows the tracked vehicle to turn on the spot.
    DE 10 2008 016 282 B3 discloses a snow vehicle which has a central vehicle body and two drive units which are arranged laterally outside and parallel to it and have the same mirror image, each with a drive chain.
    US 2006 157 290 A1 discloses a caterpillar off-road vehicle or caterpillar ATV (ATV = All Terrain Vehicle), which has a central frame on which a track drive is arranged on each side. There is a seat for at least one person above the chain drives. The / 31
    37071 present off-road vehicle is built like a quad, but instead of the four edges it has two chain drives. Due to the elevated arrangement of the seat over the chain drives, the entire vehicle has an unfavorable, high center of gravity. This high center of gravity is particularly noticeable when driving across a slope.
    The object of the present invention is to develop a snow vehicle so that a better and safer drive in a steep slope area is possible with it.
    The object of the invention is achieved by the technical features of claims 1 and 2.
    It is an essential feature of the invention that the seat, a loading area or a load is connected to the longitudinal members of the chassis via at least one joint and that at least one adjustment means regulates the position between the seat (or the load) and the chassis and thus the seat ( or the load), regardless of the chassis, is always in a flat, horizontal position.
    In a first preferred embodiment, the snow vehicle has a seat which is designed for sitting for a single person. However, the embodiment according to the invention is not limited to this. Of course, the snow vehicle can also have a plurality of seats which are arranged one behind the other, next to one another, one above the other or offset from one another. Furthermore, a seat for at least one person can also be arranged on the snow vehicle instead of a seat.
    The seat for the at least one person is preferably located at the level of the chain drives. As a result, a very low center of gravity is achieved in particular. This has a positive effect on driveability in the slope area.
    / 31
    37071
    In a second preferred embodiment, the snow vehicle is designed as a self-propelled, remote-controlled work vehicle for the transport of at least one load. Instead of the seat, the load is now connected to the longitudinal member of the undercarriage via at least one joint, at least one adjusting means effecting position control between the load and the undercarriage.
    The chain drive of the snow vehicle preferably has a track chain, a drive wheel and an opposite guide wheel. The drive wheel transmits power from the engine to the chain.
    In addition to the drive wheel and the guide wheel, the chain drive can also have at least one additional wheel. This is preferably located centrally between the drive wheel and the guide wheel. The impeller is advantageously adjustable. For example, a hydraulic cylinder, a cable or the like can be used as the adjusting device for the impeller. The adjustment device makes it possible for the impeller to move upward (away from the bottom surface), as a result of which the entire chain, in particular in the load section, is tensioned. This results in improved traction with the chain drive.
    If the wheel is moved downwards (in the direction of the floor surface) with the adjusting device, the snow vehicle moves particularly agile, since the contact area of the chain is reduced as a result. This means that the snow vehicle sometimes only has ground contact with the chain in the area of the adjustable impeller - the drive and guide wheels are further away from the ground surface.
    The present invention understands by the drive, guide and running wheels disk-shaped objects which are rotatably driven and transmit the power of the motor to the chains. Of course, instead of the drive, guide and impellers, gears can also be used on the snow vehicle 1/31
    37071 can be used. These are synonymous. All wheels (drive, guide, and running wheels) can also be driven.
    The track chain consists, for example, of metal or a composite material. Rubber tracks are preferred for the snow vehicle. The chain is divided into a load section (also work section, train section) and an empty section. The load section is the lower of the two sections, is taut and has direct contact with the floor surface. The empty strand section is the upper of the two sections, is slack or sags and is spaced from the floor surface.
    In a preferred embodiment, the seat of the snow vehicle according to the invention is at the height of the two empty run sections. A particularly low center of gravity is thereby achieved in particular. The motor for the chain drives is also at the level of the empty section.
    In a second preferred embodiment, the seat is arranged at the level of the two empty run sections. The engine is then between the two chain drives behind the seat.
    In a third preferred embodiment, the seat is arranged between the empty strand and load strand sections. The seat is located approximately at the height of the axles of the drive wheel and the guide wheel.
    At least one control panel for controlling driving operation is arranged in the area of the seat. This control panel is ergonomically located on one of the armrests of the seat.

    A hydrostatic drive can be used to drive the chain drives, for example, which converts the mechanical power of the engine (electric motor; diesel; gasoline engine) into hydraulic power by means of a pump (driven machine) on the primary side. Furthermore, a diesel-hydraulic power transmission is also possible, for example, in which the mechanical energy emitted by a diesel engine is transmitted hydraulically to the chains. Of course, the use of an electric motor is also possible, which has a high efficiency and an uninterrupted torque output.
    In a further embodiment, the vehicle has adjustment means with which it can raise or lower the individual wheels. The adjusting means are, for example, hydraulic cylinders, two hydraulic cylinders advantageously being assigned to each chain drive. The hydraulic cylinders are arranged at a distance from one another along the longitudinal axis of the chain drive. Both hydraulic cylinders extend in the direction of the center of the chain drive and are connected there to a cross member via a connecting block and a joint. The four hydraulic cylinders can be used to raise or lower the crawler tracks on one side and / or on both sides. This makes it possible to lift the drive wheel or the guide wheel onto a shoulder.
    When negotiating a step or edge, the snow vehicle is driven to the edge. The front left or right drive or guide wheel of the chain drive is then raised using the hydraulic cylinders and placed on the heel by moving the chain drive forward. The same process can take place with the second chain drive. Then both front drive or guide wheels are on the heel. The snow vehicle can now drive over the heel.
    In a further preferred embodiment, the snow vehicle has hydraulic cylinders which are used for tilt compensation or adjustment / 31
    37071 of the seat opposite the chassis or the chain drive. For example, if a person is driving up a slope with the snow vehicle, the four hydraulic cylinders compensate for the slope of the slope relative to the seat. This means that the lower hydraulic cylinder (valley side) is extended further than the higher hydraulic cylinder (mountain side). The person to be transported is therefore always on a level seat when negotiating an incline.
    The subject matter of the present invention results not only from the subject matter of the individual patent claims, but also from the combination of the individual patent claims with one another.
    All of the information and features disclosed in the documents, including the summary, in particular the spatial configuration shown in the drawings, are claimed to be essential to the invention insofar as they are new to the prior art, individually or in combination.
    In the following, the invention will be explained in more detail with reference to drawings showing only one embodiment. Here, from the drawings and their description, further features and advantages of the invention that are essential to the invention emerge.

    In the following, it should be assumed that the snow vehicle 1 is designed for the transportation of people. However, it is also possible for a loading area 21 or a device for the transport of loads to be provided instead of the seat 2. The snow vehicle 1 is then an implement carrier or a self-propelled work machine which can be controlled with a remote control. The loading area 21 or the coupled implement can then, like the seat 2, be moved with the adjusting means 41 or the hydraulic cylinders 8, 9, 10 and 11 or aligned with the chassis 22. Furthermore, it is possible for a loading area 21 to be present in front of or behind the seat 2.
    With the figure 1, the snow vehicle 1 is e.g. a snow-covered floor surface 19 is shown. The snow vehicle 1 has a chassis 22. Above the chassis 22 there is a seat 2 with a seat 20 for one person.
    The undercarriage 22 consists of two parallel longitudinal members 6, each having a drive wheel 14 in the front area and a guide wheel 15 in the rear area. According to FIG. 1, an additional impeller 38 is arranged between the drive wheel 14 and the guide wheel 15. In the present embodiment, the drive wheel 14 is in the front in the direction of travel. However, it is also possible for the drive wheel to be at the rear in the direction of travel. Furthermore, all wheels 14, 15 and 38 can also be driven.
    The wheels 14, 15 and 38 are surrounded by a chain 5 and together form the chain drive 3, 4. With the chains 5, the snow vehicle 1 is in contact with the floor surface 19.
    It can be seen from FIG. 1 that the seat 2 is arranged between the chain drives 3, 4, the seat surface 20 being below the / 31
    37071
    Leertrum 18 is located. A particularly low center of gravity is achieved by this arrangement.
    FIG. 2 shows the undercarriage 22 of the snow vehicle 1. The undercarriage 22 essentially consists of longitudinal members 6 which are parallel and spaced apart from one another and are oriented in the direction of travel, on each of which a drive wheel 14 and a guide wheel 15 are arranged.
    The longitudinal beam 6 has a connecting block 40 along its longitudinal extent, preferably in the middle, on which adjustment means 41 engage. The adjustment means 41 are preferably designed as hydraulic cylinders 8, 9, 10 and 11 and are arranged between the connecting block 40 and the respective end points of the side members 6. The connecting block 40 is connected to the side member 6 by a joint 7.
    According to FIG. 3, a cross member 23 runs between the two connecting blocks 40 on the right and left side, which serves as a fastening for the seat 2 or the at least one carrier 37 for the load 36. The connecting block 40 is preferably T-shaped, wherein it is rotatably connected to the longitudinal beam 6 at its lower end via a joint 7.
    FIG. 4 shows a side view of the snow vehicle 1 according to the invention. The joints 7, the adjusting means 41 and the connecting blocks 40 enable the position of the chassis 22 and the seat 2 to be compensated for. Position compensation is understood here to mean that the seat 2 with its seat surface 20 can assume a different position relative to the floor surface 19 than the undercarriage 22. This makes it possible for the undercarriage 22 to assume a certain angle due to an incline 12 of the floor surface 19 , the seat 2 or its seat 20 nevertheless has a balanced, right-angled seating position for the person to be transported.
    / 31
    37071
    In order to achieve a defined position compensation between the seat 2 and the undercarriage 22, adjusting means 41 are arranged on the two sides of the parallel longitudinal beams 6. Any working member that performs mechanical work can be used as the adjusting means 41. For example, a pneumatic or hydraulic cylinder can be used as the adjusting means. A spring or another elastic element is also possible.
    In a preferred embodiment, hydraulic cylinders 8, 9, 10, 11 are used as adjusting means 4. Each longitudinal member 6 preferably has two hydraulic cylinders 8 and 11, and 9 and 10 as adjusting means 41, with each wheel 14, 15 being assigned a hydraulic cylinder 8, 9, 10, 11, by means of which the respective wheel can be raised or lowered. Thus, two hydraulic cylinders 8 and 9 are assigned to the two front wheels 14 in the direction of travel. And each of the two rear wheels 15 is assigned the hydraulic cylinders 10 and 11.
    The connecting block 40 is preferably T-shaped and rotatably connected to the longitudinal beam 6 via a joint 7. The two hydraulic cylinders 9 and 10 are arranged between the connecting block 40 and the side member 6. The hydraulic cylinders 9, 10 can act freely through the joint 7.
    FIG. 5 shows the snow vehicle 1 when driving on an incline 12. The undercarriage 22 is inclined parallel to the ascending incline 12. The seat surface 20 of the seat 2 has assumed a flat position through the adjustment means 41. The person to be transported can thus just sit on the seat 2.
    The difference in position between the chassis 22 and the seat 2 is achieved by the adjusting means 41 or the hydraulic cylinders 8, 9, 10, 11. The hydraulic cylinder 9, which is assigned to the front wheel 14, is extended less than the rear hydraulic cylinder 10, which is assigned to the rear wheel 15. This will automatically position control between / 31
    37071
    Undercarriage 22 and the seat 2 reached. The location control makes it easy to drive on steep roads. The passenger to be transported is always sitting straight on his snow vehicle 1.
    In a preferred embodiment, a reservoir 25 is arranged per hydraulic cylinder 8, 9, 10, 11, which serves as a damper for the respective liquid. For example, nitrogen can be used as bladder storage to dampen or control the system. Until the position control control circuit responds, this accumulator processes pressure peaks that occur. When driving over small obstacles, the nitrogen bladder accumulators serve as damping or suspension. This compensation takes place independently.
    In a further embodiment, the left and right hydraulic cylinders 8, 9, 10, 11 can be actuated by the operator via a black and white valve at the push of a button. However, the entire control must then be controlled manually by the driver.
    The snow vehicle is controlled exclusively with the chain drives 3, 4, which are driven independently of one another. The steering movement is preferably effected by the different speeds of the chains 5 of the chain drives 3, 4. The drive of the chain drives 3, 4 can even take place in opposite directions, as a result of which the snow vehicle 1 turns on the spot.
    FIG. 6 shows an example of the force distribution of the individual hydraulic cylinders 8, 9, 10, 11 on the respective drive and guide wheels 14, 15, which is used for a steering movement of the snow vehicle 1. The steering movement takes place through the targeted activation of two different hydraulic cylinders 8, 9, 10, 11. These are two diagonally arranged hydraulic cylinders, e.g. Cylinders 9 and 11 or 8, 10, through which a diagonal bias is generated. This changes the weight shift and is now 45% on two wheels and 5% on the other two wheels.

    37071
    It is shown on the basis of FIG. 7 that with the snow vehicle 1 essential to the invention, an obstacle such as e.g. a level 13 is not a problem. As soon as the front wheel 14 comes into contact with the step 13, the oil pressure on the piston ring surface of the e.g. rear hydraulic cylinder 11. At this moment, a signal is automatically sent to a controller. Now the different oil pressures in the cylinders are compensated for by the built-in position control, which acts on all four hydraulic cylinders 8, 9, 10, 11. Oil flows from the rear cylinders 10, 11 into a buffer, the front cylinders 8, 9 get more oil. Thus, the snow vehicle 1 is suspended over the level 13. The passenger is thus always sitting straight on the vehicle 1 and is not “shaken”.
    Figure 8 shows the approach of the snow vehicle 1 to a step 13. The two front wheels 14 are relatively close to the step 13. The driver of the snow vehicle 1 now lifts by pressing a button e.g. the right front wheel 14 via the respective hydraulic cylinder 9. During this process, the further hydraulic cylinders 8, 10 and 11 are regulated by a position control. In particular, the rear right hydraulic cylinder 10 is automatically extended. The driver of the snow vehicle 1 now moves the raised front wheel 14 to the step 13 with the aid of the chains 5 standing on the ground.
    FIG. 9 shows a side view of the snow vehicle 1 according to the invention. The chain 5 is divided into two strand areas. A strand is understood by the present invention as a free, non-lying section of the chain 5. On the upper side of the chain there is the empty strand 18. On the lower side of the chain 5 there is the load strand 17, which is in direct contact with the bottom surface 19 stands.
    The empty strand 18 has a height 28 with respect to the bottom surface 19, while the load strand 17 has a height 26 with respect to the bottom surface 19. The seat surface 20 in turn has the height 27 relative to the floor surface / 31
    37071 to 19. The height 27 of the seat surface 20 is preferably lower than the height 28 of the empty strand 18. As a result, the person sits below the empty strand 18, which in particular achieves a particularly low center of gravity.
    According to FIG. 9, the seat surface 20 (height 27) is thus between the height 26 (empty strand 18) and height 28 (load strand 17). However, it is also possible for the height 27 to correspond to the height 26. The seat surface 20 of the seat 2 is then at the height 26 of the empty strand 18.
    FIG. 10 shows a further embodiment of the snow vehicle 1 according to the invention. Instead of the hydraulic cylinders 8, 9, 10, 11, a double-acting hydraulic cylinder 24 is now arranged on each side of the side member 6. The double-acting cylinder 24 has two opposite piston surfaces which are acted upon by hydraulic fluid. The cylinder 24 thus has two active directions of movement. In this exemplary embodiment, the snow vehicle 1 only required two double-acting hydraulic cylinders 24 instead of the usual four hydraulic cylinders 8, 9, 10, 11.
    Figure 11 shows the snow vehicle 1 when moving a load 36 which is guided on a slide 34 with runners 35. The slide is preferably arranged 34 in front of the snow vehicle 1. However, it is also possible for the carriage 34 to be arranged behind the snow vehicle 1 and to be pulled thereby.
    It can be seen from FIG. 12 that the carriage 34 is connected to the snow vehicle 1 by way of two carriers 37 which are in question. The carriers 37 are rigid. The carriers 37 are preferably designed as profile carriers and releasably connected to the seat 2 or to the cross member 23. For example, a coupling or a plug connection can be used as a releasable connection.
    / 31
    37071
    In a preferred embodiment, the carriers 37 are designed as three-point linkages. The carriage 34 is thus attached to the snow vehicle 1 at three points. Such three-point linkages are preferably used in agricultural machinery.
    FIG. 13 shows the snow vehicle 1 with the load 36 raised. The carriers 37 are in this case arranged on the cross member 23, which is inclined or rotatable by the adjusting means 41. This means that by means of the hydraulic cylinders 8, 9, 10, 11 the slide 34 and the load thereon can be raised or lowered relative to the floor surface 19.
    In FIG. 13, the seat surface 20 of the seat 2 of the snow vehicle 1 is inclined to the rear. The hydraulic cylinders 8 and 9 are thus extended, while the hydraulic cylinders 10 and 11 are retracted. In general, the seat surface 20 is always inclined with the adjusting means 41 when a compensation of the seat surface 20 with respect to the chassis 22 is required. According to FIG. 13, however, the inclination of the seat surface 20 is deliberately used to raise or lower the supports 37. This makes it possible for the first time to specifically lift the load 34 relative to the floor surface 19.
    FIG. 14 shows the snow vehicle 14 with the drive wheels 14 raised and the load 34 removed. The drive wheels 14 are raised by the adjusting means 41.
    It can be seen from FIG. 15 that the snow vehicle 1 can also travel over a step 13 with a sled 34. For this purpose, each wheel 14, 15 can be raised or lowered specifically via the hydraulic cylinders 8, 9, 10, 11.
    In a further preferred embodiment, the seat 2 has, in addition to a position control in the longitudinal direction of the snow vehicle 1, an additional side tilt control in the transverse direction of the on snow vehicle 1.
    / 31
    37071
    For this purpose, additional adjustment means 41 are used, which raise or lower the cross member 23 and thereby compensate for the position of the seat 2 or the seat surface 20 in e.g. cause a side slope of the snow vehicle 1. The lateral inclination is preferably detected automatically and counteracted with the aid of a control unit and the adjusting means 41. With a tilt adjustment display and an operating unit, the set inclination can also be manually confirmed or kept independent of the inclination of the chassis 22.
    The snow vehicle 1 thus has a position control for the seat 2. The position control essentially consists of adjusting means 41, which incline or tilt the seat 2 or its seat surface 22 with respect to the chassis 22 in the longitudinal direction of the snow vehicle 1. The position control can also be used to raise or lower individual wheels 14, 15 of the chain 5. Furthermore, the position control can be used to raise a load 36. For this purpose, the seat 2 or the cross member 23 can be coupled to a carriage 34 via the carrier 37, the load 36 being raised with the aid of the adjusting means 41 during a tilting movement of the seat 2.
    According to FIGS. 11 to 15, loads 36 can be transported with the snow vehicle 1. The loads 36 stand on runners 34. The connection of the load 36 to the snow vehicle 1 takes place via the carrier 37 on the seat 2. By coupling the load 36 to the snow vehicle 1 and the possibility of lifting this load 36 (FIG. 13) or lower (Figure 14) and the associated shift in the center of gravity, a higher stability of the snow vehicle 1 is achieved in the terrain on steep inclines or descents.
    In particular, by combining the snow vehicle 1 with a load 36 that can be coupled, which stands on runners 34, the entire vehicle is extended, as a result of which better stability is achieved in the terrain.
    / 31
    37071
    Figures 16 and 17 show the snow vehicle 1 with an adjustable impeller
    38. The height-adjustable impeller 38 in the area of the chain drive 3, 4 results in the advantage that the traction capability or maneuverability of the snow vehicle 1 is increased. For this purpose, the chain drives 3, 4 have, in addition to the drive wheel 14 and the guide wheel 15, an additional wheel 38 which is located centrally between the drive wheel 14 and the guide wheel 15. The impeller 38 is designed to be adjustable and can be moved, for example, in the longitudinal direction of the snow vehicle 1 or in height. For example, a hydraulic cylinder, a cable or the like can be used as the adjusting device for the impeller 38.
    According to FIG. 16, the impeller 38 is moved upwards in the direction of arrow 29 with the aid of the adjusting device, i.e. moved away from the bottom surface 19, whereby the entire chain 5, in particular in the load section 17, is tensioned. This results in improved traction with the chain drives 3, 4. This has a positive effect on steep inclines or descents, for example.
    According to Figure 17, the impeller with the adjusting device in the direction of arrow 30 is down, i.e. in the direction of the bottom surface 19. As a result, the snow vehicle 1 is particularly agile because the contact surface of the chain 5 is reduced to the load section 17. This means that the snow vehicle 1 has only some contact with the ground with the chain 5 only in the region of the adjustable impeller 38. The drive and guide wheels 14, 15 are further away from the bottom surface 19.
    It is crucial that the snow vehicle can also be used to transport loads as a self-driving, remote-controlled work vehicle. Instead of the seat 2, devices or loads can then be transported on the loading area 21 with the snow vehicle 1. This is illustrated by FIG. 18, which shows snow vehicle 1 as a self-propelled, remotely controllable working machine (without seat 2) with a loading area 21. On / 31
    37071 of the loading area 21, for example, tools, working machines, aids, food or drinks can be stowed away and transported safely.
