Description

Technical Field

[0001] The utility model relates to the field of automobile manufacturing, and more specifically to a height-adjustable torsion shaft suspension structure. Background Art

[0002] In the use of small or light automobile suspension, non-independent or semi-independent suspension is often used to reduce costs. However, the current non-independent suspension, such as the integral bridge structure, brings great challenges to the layout of the vehicle space, or increases the vehicle height, or reduces the ground clearance, etc. The use of a semi-independent torsion beam structure can appropriately avoid the space problem with the floor during the wheel jumping process, but due to the limitation of the structural form, the development cost and the use cost will inevitably increase;

[0003] In this case, it is necessary to simplify the rear axle structure to avoid using the entire axle structure to reduce layout space as the wheel bounces. The height of the vehicle body can also be lowered to increase ground clearance. The height of the vehicle can also be adjusted according to the needs of different models, and the suspension stiffness can be changed, which greatly reduces the cost of use and shortens the development cycle. Utility Model Content

[0004] The main technical problem solved by the utility model is to provide a height-adjustable torsion shaft suspension structure, which can avoid using the entire shaft structure to reduce the layout space due to the wheel bouncing, and can also reduce the vehicle height and increase the ground clearance. The vehicle height can also be adjusted according to the requirements of different vehicle models, and the suspension stiffness can be changed, while greatly reducing the use cost and shortening the development cycle.

[0005] To solve the above technical problems, according to one aspect of the utility model, more specifically, a height-adjustable torsion shaft suspension structure includes a circular shaft tube, an adjusting bolt fixing bracket, an adjusting bolt fixing block, an adjusting bolt, an adjusting nut, an adjusting arm, a steering knuckle, a spline shaft seat, an adjusting bolt pad, an adjusting arm stopper 1, an adjusting arm stopper 2, an inner sleeve, a spline shaft, a rubber sleeve, a bayonet, a groove, a notch right groove, a round hole, a connecting circular groove, a connecting hole and a limiting hole; the circular shaft tube is fixedly connected to the adjusting bolt fixing bracket by welding, the inner sleeve is fixedly connected to the steering knuckle by welding, and the rubber sleeve is engaged with the inside of the circular shaft tube The adjusting arm stop block 1 and the adjusting arm stop block 2 are fixed at the bayonet, the adjusting arm and the adjusting arm stop block 1 and the adjusting arm stop block 2 are fixedly connected to the outer side wall of the circular shaft tube, the adjusting bolt fixing block is fixedly connected to the groove, the left end of the adjusting bolt extends to the notch, the adjusting bolt passes through the adjusting bolt lower pad and extends to the inside of the right groove, the inner sleeve is fixedly connected to the steering knuckle by welding and is clamped with the inner side wall of the circular shaft tube, the spline shaft extends to the inside of the connecting circular groove through the circular hole, and the spline shaft seat is bolted to the connecting hole and the limiting hole.

[0006] Furthermore, the circular shaft tube and the adjusting bolt fixing bracket are an integrated structure, the circular shaft tube is connected to the axle to form a torsion beam structure, and the adjusting bolt and the fixing bracket are a cantilever structure.

[0007] Furthermore, the steering knuckle and the inner sleeve are an integrated structure and are interference fit with the rubber sleeve and the circular shaft tube.

[0008] Furthermore, the steering knuckle and the brake are an integrated structure and are connected to the circular shaft tube by snap-fitting with the spline shaft.

[0009] Furthermore, the adjusting arm stopper 1 and the adjusting arm stopper 2 are welded to both sides of the bayonet and become one with the circular shaft tube and the adjusting arm fixing bracket, and the adjusting arm, the adjusting bolt and the adjusting bolt pad are fixedly connected.

[0010] The beneficial effects of the height-adjustable torsion shaft suspension structure of the utility model are:

[0011] The combined structure of the circular axle tube, steering knuckle, and adjustment bolt fixing bracket can be directly installed and fixed to the vehicle body, replacing the circular torsion beam Chen Tao installation bracket, which can strengthen the connection rigidity between the rear axle and the vehicle body. The structure is simple and easy to assemble, which can ensure the consistency during mass production, effectively improve the load-bearing capacity, and ensure the reliability of use.

[0012] The steering knuckle, rubber sleeve, inner sleeve and the circular shaft tube are integrated after interference fit, which plays a role in fixing the wheel and buffering the forces in all directions, thus ensuring the movement performance of the wheel. The processing and manufacturing are simple and the consistency of the production process can be guaranteed.

[0013] The set adjustment arm, adjustment bolt, adjustment bolt pad 1 and adjustment bolt pad 2 are connected by adjusting nuts. By adjusting the nuts, the tightening length of the nuts is continuously adjusted until the wheel angle or vehicle height meets the requirements. The height difference between the left and right wheels can also be adjusted by the angle between the spline shaft seat and the spline shaft, which can effectively balance the force, ensure vehicle performance, and increase the flexibility and application range of vehicle adjustment;

[0014] According to the changes in weight of different vehicle models, the size of the spline shaft is adjusted, such as the length and diameter of the spline shaft, to change the suspension stiffness. The adjustment range is small, the development cost is low, and the cycle is short. BRIEF DESCRIPTION OF THE DRAWINGS
