    1518922 Driving steerable wheels INVENTIO AG 10 Feb 1977 [17 Feb 1976] 05472/77 Heading B7H The steerable front wheels 1, 2 of a tractor are driven through double universal joints 9, 10 by half shafts 7, 8 which are interconnected by a central universal joint 6 and disposed at an angle to maximize the possible steering lock by taking into account the greater angle through which the inner wheel is turned than the outer when the wheels are steered.

    CD The invention relates to the control of drive axles of vehicles with a drive through a double universal joint on each wheel. With known front-wheel drive or all-wheel drive vehicles, the drive is from a shaft, both ends of which are connected with double cardan joints. But since a change in the angular position of the drive shaft with respect to the driven shaft in the cardan joint is only possible to a certain extent, because in the npOTjj case, the cardan joint would be overloaded or fractured to turn the wheels when the drive axle is driven. species set certain limits. A driven vehicle driven mosquito is known, comprising wheels, double universal joints, one end of each KOTOJXJX connected with a corresponding wheel and two with a water shaft located in a horizontal plane, each with its other end corresponding to double cardan joint, and the other end - with a simple cardan joint. With the aid of a known controlled drive axle, it is achieved that the angle of inclination of the wheel to the road bed does not change upon hitting. wheels on the obstacle. In this case, the drive shaft associated with this wheel is deflected at an angle in the vertical plane 1. A disadvantage is the low maneuverability of the vehicle with the said front axle, and the lack of use of the angular mobility of the double-pivot double joints. so that, by simplifying the design, it can achieve a significant improvement in the controllability of the drive axle by fully utilizing the angular mobility of both double cardan joints. In addition, it is necessary to achieve a further reduction in the distance between the front and rear wheels, which, in particular, for a tractor equipped with such a drive axle, has a certain value for its connection with the harvesting machines and so forth cannot be reduced due to caused by the name of the space of the front differential box. The purpose of the invention is to increase the maneuverability of the vehicle. The goal is achieved by the fact that in a controlled drive axle of a vehicle containing wheels, double universal joints, one end of each of which is connected to a corresponding wheel, and two drive shafts located in a horizontal plane, each of which is connected by one end with the other End of the corresponding double cardan joint, and the other end with a simple cardan joint, the simple cardan joint is located on the longitudinal axis of the vehicle at a distance from the straight passage through the center of the internal 111arnirov dvoynsh joints and drive shafts are at an angle to said straight in the horizontal plane, wherein said angle is equal to half the largest quantities joy angles of both wheels at their maximum rotation. Fig. 1 shows a diagram of a vehicle with a controlled drive front axle in Fig. 2, an embodiment of a structural embodiment of the bridge. The front wheels 1 and 2 of the tractor Fig.1) are turned to the right so that the tractor would travel along a curve around the center point 3. This center point of the curve is ha distance from the longitudinal center line 4 of the tractor extending the rear axle 5. Distance between the axles of the front and rear wheels is indicated. the letter b, and the distance between the wheels is c. . On the longitudinal axis 4, in the area of the front axle, there is a simple universal joint b, two drive shafts 7 and 8 depart from it to double cardan joints 9 and 10, by means of which the wheels 1 and 2 are driven and simultaneously through internal hinges 11 and 12 both double cardan joints pass through the line 13, with which both crankshafts 7 and 8 form an angle y. O) The remaining universal joint 6 is located in front of this communication line in the middle of the longitudinal axis 4 of the vehicle, therefore the angles f on both sides are equal to each other. At an angle of. the rotation of the wheel 1 located on the outer side of the trajectory and the much larger angle of rotation p of the wheel 2 located on the inner side of the trajectory are predominantly the angle — l / 2 (p-ci), i.e. the angle is equal to half the difference between the different angles of rotation of both wheels at the maximum turn, because then the angular positions of both double universal joints 9 and 10 on the inner and outer sides of the trajectories are equal to the maximum turn of the wheels, as can be seen from the drawing. If, for example, the angle / s of rotation of the wheel located on the inner side of the trajectory reaches 60 °, and the angle ot of rotation of the wheel located on the outer side of the trajectory reaches 44, then the angle J 8, i.e. half the difference between 60 and 44®. Due to this arrangement, the rotation of the double gimbal 10 located on the inside of the trajectory 10 in relation to the angle of rotation of the wheel 2 is less at an angle, and the rotation of the double cardan joint 9 located at the outer side of the trajectory of the double universal joint 9 is greater at the angle y. Due to this, the possibility of turning both double cardan joints is fully utilized. The lead shaft 7 on the left side is driven by a large bevel wheel 14 which engages with a small bevel wheel 15. With this
    the arrangement of the axle drives of the small and large bevel wheels intersect at an angle which is less than 90 ° through the angle y.
    The advantage of the invention is also that the axle spacing tf between the front and rear wheels becomes smaller if it comes from the differential of the front axle, located in the place of the universal joint b, through which the non-bent direct drive shaft passes, when ets the differential position is set to considering the location of the place. Therefore, due to the bending of the drive shafts 7 and 8, the front wheels can be shifted a little further down compared to their position with the forward drive shaft.
    The invention improves vehicle maneuverability.
