BRIEF DESCRIPTION OF THE DRAWINGS
Some embodiments of the invention are explained in more detail in the accompanying drawings, in which Fig. 1a schematically shows an arrangement according to the invention from above, Fig. 1b schematically shows a side view of Fig. 1a, and FIG. 2b schematically illustrates the arrangement of FIG. 1a in a second position and from above.
In the figures, some embodiments of the invention are shown in simplified form for clarity. Like parts are denoted by like reference numerals in the figures.
Detailed description
Fig. 1a is a diagrammatic view of an arrangement according to the invention for attaching a implement to a vehicle from the top, Fig. 1b from the side, and Fig. 1c from the bottom. Arrangement 100 functions as a fastening and guiding element between vehicle V and implement W. Arrangement 100 can control the up / down movement of the implement W and the angle relative to the vehicle V.
Vehicle V may be, for example, a truck, a tractor, a grader, a brush25 blower, a Telescopic Forklift, a Wheel Loader, etc. The vehicle is shown with some of its wheels and a part of its axle box.
The working implement W shown in the figures is a lower blade that can be used to move soil, snow, gravel, etc., to level the road surface or other road surface, etc. for work tasks. Note that the implement may be something other, such as a 30 brush, a washing machine, and the like.
Arrangement 100 is secured to vehicle V on this axle portion using first securing means 2. More specifically, the first securing means 2 comprises a front end securing means 2a for securing to the front end of vehicle V and a rear end securing means 2b,
20185107 prh 07-02-2018, which in turn are intended to be mounted rearwardly than the front end attachment means 2a.
The fastening means 2 can be implemented as a quick lock, whereby the arrangement can be secured to the vehicle in a detachable manner. According to another idea, the fastening means 2 are fastened to the vehicle in a manner intended to be permanent, for example by bolting or welding.
Arrangement 100 has a subframe 1 for attachment to vehicle V, comprising, in addition to the first securing means 2, second securing means 3 for securing the implement to arrangement 100. In one embodiment, the second securing means 3 comprises fasteners for fastening and detaching the implement W
It should be noted in this connection that the arrangement 100 may further comprise connectors and coupling means, for example, for transmitting signals, electricity and pressure medium between the vehicle V and the implement W.
The subframe 1 has a body part 4 having a longitudinal centerline
X, which is centered at least substantially longitudinally of vehicle V. Said second fastening means 3 are disposed in the frame part 4, between the front end fastening means 2a and the rear end fastening means 2b.
The subframe body portion 4 is secured to the front end attachment means 2a and the rear end attachment means via the front end and rear end joints 20 5a, 5b.
2b. The body portion 4 is coupled to the front end mounting means 2a via an adjustable height adjustment element 6 so that the subframe body portion 4 can be tilted relative to the first mounting means 2 by adjusting the height adjustment element 6. Thus, the height position of the second attachment means 3 mounted on the subframe body 4 and the attachment device W attached thereto is adjustable relative to the vehicle V. The height adjusting elements 6 are disposed near the front end of the arrangement 100 near the front axle of the vehicle so that they do not impede access to the vehicle cab or visibility from the cab.
In another embodiment, the body portion 4 is connected to the rear end joints 5b instead of the joints of the front end 30 via an adjustable height adjusting element 6: in this embodiment, the height position of the implement W is adjusted as described above.
In one embodiment, the height control element 6 is a pressure medium cylinder, wherein the pressure medium is pressure fluid or compressed air. Of course, the height adjustment element 35 can be implemented in other ways, for example electromechanical.
20185107 prh 07-02-2018
The operation of the height adjustment element 6 is controlled by a control unit 13 comprising a user interface for use by a vehicle user. Alternatively, the control unit 13 comprises switching means for switching on the operation of the arrangement 100 from the vehicle V interface.
In the embodiment shown in the figures, the subframe body 4 is a two-piece body comprising a body front part 4a having front end joints 2a and other fastening means 3 and a rear body part 4b having rear end joints 2b. The body front 4a and the rear body 4b are secured to one another by a joint 7 allowing rotation of the implement W and the rear body 4b of the body 4a - and thus also of the other attachment means 10 - about a longitudinal center line X of rotation.
The distance between the front end joints 2a and the rear end joints 2b changes as the inclination of the body part 4 changes. According to one idea, the length of the body portion 4 adjusts according to the inclination. In the embodiment shown in the figures, the hinge 7 is variable in length so that the length of the body 4 can be varied as it is tilted. Of course, the variable length body 4 can also be arranged in other ways, and thus the joint 7 is not necessary in this respect either. According to another idea, the height adjusting element 6 is pivotally mounted on the vehicle so that it can rotate with the inclination of the frame 4 20 so that the variable length of the frame is not necessary.
The arrangement 10 further comprises two height adjusting elements 6 disposed on the front part 4a of the frame, at a distance from the axis of rotation A and on both sides thereof. By adjusting the height adjusting elements 6, the front part 4a of the frame and the implement W are rotated with respect to the implement V in the direction of the axis of rotation A, etc.
Thus, in the embodiment shown in the figures, the height adjustment elements 6 and the second fastening means 3 are fixed to the front part 4a of the frame. In another embodiment, the height adjustment elements 6 and the second fastening means 3 are fixed to the rear of the body 4b.
According to one idea, the arrangement 100 comprises a sensor arrangement
10, which is arranged to indicate the status of the implement W attached to the arrangement, for example the position of the implement.
The sensor arrangement 10 has at least one sensor or sensor 11 for detecting the status of the implement. The sensor or sensor 11 is coupled to the sensor unit 12 which processes the signal from the sensor or sensor.
20185107 prh 07-02-2018
In one embodiment, the status of the implement is transmitted to the control unit 12 or further to the V interface of the vehicle. In one embodiment, the movements of the implement W are limited so that it does not collide with the V parts of the vehicle, such as, for example, a fuel tank or the like.
Fig. 2a schematically shows the arrangement according to Fig. 1a in the first position and from the top, and Fig. 2b in the second position and from the top.
The subframe body portion 4 comprises a turntable 8 which is pivotable by an actuator 9 about a second rotary axis B arranged perpendicular to the center line X. The second securing means 3 are disposed on the turntable 8 so that they - and the implement W - are rotatable with respect to said second axis of rotation B. Figures 2a and 2b show, by way of example, two different positions of the turntable 8.
In the embodiment shown in the figure, there are two actuators 9 which are pressure medium-acting cylinders. The operation of the actuator 9 is controlled by the control unit 12 as described above.
In summary, the arrangement of the invention is characterized in that the first fastening means comprises a front end fastening means, a rear end fastening means to which the subframe body is secured through the front end and rear end hinges, and the subframe body part through such that the subframe body is tiltable relative to the first fastening means by adjusting the height adjustment element, wherein the height of the second fastening means fitted to the subframe body is adjustable with respect to the vehicle.
The drawings and the description related thereto are only intended to illustrate the idea of the invention. It will be apparent to one skilled in the art that the invention is not limited to the embodiments described above, in which the invention is illustrated by some examples, but that many modifications and various embodiments of the invention are possible within the inventive concept defined by the claims below.
