Detailed Description

In fig. 1, the upper end of a left telescopic rod 2 is fixed on a frame structure 1 at the left side of the bottom of a vehicle in a mode of a shaft sleeve and a hinge pin, the axis of the hinge pin is parallel to the ground, and the axis of the hinge pin is vertical to the axis of a wheel; the upper end of the right telescopic rod 3 is also fixed on the frame structure 1 on the right side of the bottom of the vehicle in a hinge mode of a shaft sleeve and a shaft pin, the axis of the shaft pin is parallel to the ground, the axis of the shaft pin is vertical to the axis of a wheel, and a certain axial distance is reserved between the upper end of the left telescopic rod 2 and the upper end of the right telescopic rod 3; the lower ends of the left telescopic rod 2 and the right telescopic rod 3 are fixed on the bearing plate 4 together in a hinge mode of a shaft sleeve and a shaft pin, the shaft pin on the bearing plate 4 is parallel to the ground, the shaft pin is perpendicular to the wheel axis, and the left telescopic rod 2 and the right telescopic rod 3 are in a V shape on the bearing plate 4.

When the left telescopic rod 2 and the right telescopic rod 3 are simultaneously and equidistantly extended, the bearing plate 4 touches the ground and is positioned in the middle position between the left wheel and the right wheel of the vehicle, when the left telescopic rod and the right telescopic rod continue to be extended, the vehicle is jacked up (supported), the weight on the left wheel and the right wheel is transferred onto the bearing plate 4 through the left telescopic rod and the right telescopic rod, at the moment, if the left telescopic rod 2 continues to be extended, the right telescopic rod 3 does not move, the whole vehicle is supported to the left side, then the right telescopic rod 3 is firstly shortened (retracted), the wheels fall on the position on the left side, and a lateral movement process is completed, therefore, one process can only move the vehicle to a certain lateral direction for a certain distance, if the lateral movement distance is not enough, the bearing plate 4 needs to be lifted again and placed on a position deviated to the moving direction, so as to obtain a larger movement distance of one process, and respectively control the extension stroke and the, the lateral moving direction and distance of the vehicle can be controlled, so that the function of lateral moving of the vehicle is realized.

In fig. 2, when the left telescopic rod 2 and the right telescopic rod 3 are simultaneously shortened (retracted), the bearing plate 4 is lifted and spaced from the ground by a certain distance, so that the vehicle can normally run.

For convenient operation and control, the left and right telescopic rods are provided with stroke sensors, and a program controller is adopted for motion control, the motion distance and motion sequence of the left and right telescopic rods, including the lateral moving direction of the vehicle, can be controlled by a preset program, and the lateral moving direction and distance can be temporarily and simply selected and determined by an operator and then completed by the program controller. Since the bearing plate 4 bears the weight of the rear part of the vehicle, the landing area and the mechanical strength of the bearing plate 4 are determined according to different vehicle types, and if the truck, particularly a heavy semi-trailer, is used, the landing area and the thickness of the bearing plate 4 are correspondingly increased. The left telescopic rod 2 and the right telescopic rod 3 can be hydraulic telescopic rods, can also be screw rod (spiral) telescopic rods, and can also be rack-type telescopic rods, and specifically adopt which form of telescopic rods, mainly depending on the weight of a vehicle body to be supported and the type of the vehicle, and a general small vehicle is not equipped with a hydraulic system, and just adopts an electric spiral telescopic rod, or adopts an electric rack telescopic rod, and if the vehicle is provided with hydraulic equipment, then adopts a hydraulic telescopic rod. Various shaped telescopic elements in the electromechanical industry are also numerous and can be selected according to requirements.

Because the chassis structures of various vehicles are different, the positions and conditions for conveniently installing the vehicle lateral moving device are also different, including the size of an installation space, the mechanical strength of the installation position and the like, the area of the vehicle chassis, where the vehicle lateral displacement means are mounted, is herein collectively referred to as the frame structure 1, if the vehicle lateral moving device is installed on a crossbeam of a vehicle chassis, the telescopic stroke of the left and right telescopic rods needs to be larger, the overall length thereof is also long because, when the girder of the vehicle is braced, the wheels do not leave the ground due to the shock-absorbing springs or the shock-absorbing steel plates of the rear wheels, the ideal mounting location for the vehicle lateral shifting device is on the axle structure of the vehicle, for example on the axle housing of the differential, for vehicles without a differential at the rear of the vehicle, it is mounted on a structure rigidly connected to the axle. For the vehicles additionally provided with the vehicle lateral moving devices in the later period, no existing parts are utilized whether the vehicles are arranged on the girders of the vehicles or the wheel axle structures, so that structural members are additionally arranged to be matched with the vehicle lateral moving devices according to the specific conditions of various vehicles, the structural members play the roles of fixing the parts, reinforcing the structures, dispersing pressure intensity and extending positions, and the structural members are fixed on the girders of the vehicles or the wheel axle structures in the modes of welding, bolts, clamping, hooping and the like.

In fig. 3, for some light vehicles, for some vehicles with large space in the chassis, the function of lateral movement of the vehicle can be realized by rotating the support rods. The rotary power 5 is arranged in the middle of the frame structure 1 at the bottom of the vehicle, the output shaft of the rotary power 5 is parallel to the ground and is vertical to the axis of the rear wheel of the vehicle, and the rotary power 5 can rotate clockwise or anticlockwise; a rotary support rod 6 is fixedly arranged on an output shaft of the rotary power 5, the rotary support rod 6 is arranged on the output shaft of the rotary power 5 like a propeller of an airplane and rotates synchronously, the rotary support rod 6 is perpendicular to the output shaft of the rotary power 5, the rotary support rod 6 has a certain radial length, and the outer end part of the rotary support rod 6 intermittently touches the ground and supports and moves the vehicle in the rotating process of the rotary support rod 6. At the position of the radial end of the rotation stay 6, an arc-shaped (tile-shaped) ground contact structure is provided to increase the ground contact area of the rotation stay, and the rotation locus of the radial end of the rotation stay 6 is circular as shown by the circular broken line in fig. 3. When the rotary stay bar 6 rotates counterclockwise, the end of the rotary stay bar 6 contacts the ground from the left position of the vehicle and supports the left wheel first, and then moves the whole vehicle to the left side, and when the rotary stay bar 6 rotates clockwise, the end of the rotary stay bar 6 contacts the ground from the right position of the vehicle and supports the right wheel first, and then moves the whole vehicle to the right side, thereby realizing the function of moving the vehicle laterally. The lateral movement function of the vehicle is realized by adopting the mode of the rotary support rod, the lateral movement function has the advantages of simple structure and convenient operation, and the movement of the tail part of the vehicle to the left side or the right side can be realized only by controlling the positive rotation or the reverse rotation of the rotary power 5. When the rotation stay bar 6 stops working, the rotation stay bar should stop at a position parallel to the ground to avoid the end of the rotation stay bar 6 from being hung on the road surface, and a stroke positioning switch can be arranged to limit the stop position of the rotation power 5.

The rotary power 5 mentioned in the present embodiment is a rotary power driven by a motor, having a corresponding rotation speed and torque, and having a corresponding mechanical strength, and may be a gear reducer, a turbine reducer, etc. driven by an electric motor, or may be a rotary power driven by a hydraulic motor.

When the eccentric shaft on the crank arm 7 rotates to the bottom dead center, it will touch the ground through the connecting rod strut 8 and brace the rear of the vehicle. Under the action of its own weight, the connecting rod brace 8 is normally always vertically fitted over the eccentric shaft of the crank arm 7 and kept in a vertical posture to move relative to the eccentric shaft of the crank arm 7. The radial length of the crank arm 7 plus the length of the connecting rod strut 8 should be greater than the distance between the output shaft of the rotary power 5 and the ground. The circular broken line in fig. 4 is the travel locus of the eccentric shaft of the crank arm 7. When the rotary power 5 rotates anticlockwise, the crank arm 7 drives the connecting rod type stay bar 8 to be put down from a left position of the vehicle and contact the ground, and due to the supporting effect of the lower part of the connecting rod type stay bar 8 contacting the floor, the connecting rod type stay bar 8 keeps vertical and supports the crank arm 7 to firstly support the left wheel of the vehicle and then move the whole vehicle to the left; when the rotary power 5 rotates clockwise, the crank arm 7 drives the connecting rod type stay 8 to be put down from the right position of the vehicle and contact the ground, the connecting rod type stay 8 keeps vertical and supports the crank arm 7 to firstly support the right wheel of the vehicle and then move the whole vehicle to the right side, so that the function of laterally moving the vehicle is realized.
