Description

Technical Field

[0001] The invention relates to the technical field of automobile chassis suspension systems, and in particular to a lateral thrust rod of an integral bridge of an off-road vehicle. Background Art

[0002] The lateral thrust rod of the integral bridge of an off-road vehicle is mainly used to connect the vehicle body and the integral bridge, to suppress the lateral swing between the vehicle body and the integral bridge, and to improve the vehicle's controllability and driving stability. Specifically, in the integral bridge structure of an off-road vehicle, there is usually no direct connection point between the beam and the rear axle, and various tie rods and springs are mainly used to limit the movement of the rear axle. Although this design can effectively control the front and rear and axial rotation of the rear axle, it lacks control over lateral swing. The introduction of the thrust rod is precisely to solve this problem. By fixing the left and right positions of the rear axle, it prevents the lateral displacement of the rear axle during driving, thereby improving the vehicle's handling and driving stability. In addition, the design and use of the thrust rod also need to consider the lifting and lowering of the vehicle. When the vehicle is raised, the thrust rod rotates with the fixed point of the rear axle as the center, which may cause the beam and the rear axle to be misaligned. Therefore, the existing thrust rod cannot meet the comprehensive use requirements. Summary of the invention

[0003] The purpose of the present invention is to provide a sliding thrust rod which can improve riding comfort by ensuring that the lateral center position of the vehicle body and the integral bridge does not deviate when the vehicle body bounces during driving, and has a sufficiently large suspension stroke between the vehicle body and the wheels during off-road driving to improve off-road stability, and which is low in cost and saves space.

[0004] The embodiment of the present invention provides two sets of design schemes for the sliding thrust rod: the first design scheme is composed of a sliding rod (1), a pulley box housing with an integrated pin rod (2), a U-groove pulley (3), a bearing seat and a bracket (4), and the second design scheme is composed of a slide rail (11), a slide rail reinforcement (12), a pin rod and a bracket (13), an outer pulley group (15), a pulley bracket (151), a pulley (152), and a rubber bearing bushing (153). The working principles of the two sets of design schemes are the same, and the difference is that the first design scheme mainly consists of a slide rod and an inner pulley group, and the second design scheme consists of a slide rail and an outer pulley group.

[0005] In the implementation manner of the present invention, the sliding thrust rod can be used normally without replacement when the off-road vehicle chassis is modified and raised within a certain range.

[0006] The beneficial effects of the present invention are as follows: the sliding thrust rod provided in the embodiment of the present invention connects the vehicle body with the integral bridge, and the sliding thrust rod limits the lateral position of the vehicle body and the integral bridge, but does not affect the up-and-down movement of the vehicle body and the integral bridge and the left-and-right asymmetric movement of the wheels. The sliding thrust rod provided by the present invention can improve the comfort and stability of the vehicle with the integral bridge suspension during road or off-road driving.

[0025] The features and performance of the sliding thrust rod of the present invention will be described in further detail below in conjunction with the embodiments.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the embodiment of the present invention provides a first design scheme of a sliding thrust rod, which includes a sliding rod (1) of the sliding thrust rod, a pulley box shell with an integrated pin rod (2), a U-shaped groove pulley (3), and a bearing seat and a bracket (4) combination. The sliding rod is inserted into the inner pulley group and slides up and down. The U-shaped groove pulley (3) and the sliding rod (1) limit the range of movement of each other, thus limiting the position of the transverse center of the vehicle body and the transverse center of the integral bridge. The bearing seat and the bracket (4) are longitudinally installed, and their main function is to cope with the left-right asymmetric up-and-down movement of the wheels of the integral bridge.

[0027] like Fig. 9 , Fig.10 and Fig.11 As shown, the embodiment of the present invention provides a second design scheme of a sliding thrust rod, which includes a sliding rail (11), a sliding rail reinforcement (12), a pin rod and a bracket (13), an outer pulley group (15), a pulley bracket (151), a pulley (152), and a rubber bearing bushing (153) of the sliding thrust rod. The outer pulley group (15) slides up and down in the sliding rail (11), and the sliding rail (11) and the outer pulley group (15) limit the range of movement of each other, which also limits the position of the transverse center of the vehicle body and the transverse center of the integral bridge. The pin rod and the bracket (13) and the rubber bearing bushing (153) of the outer pulley group (15) are longitudinally installed, and their main function is to cope with the left-right asymmetric up-and-down movement of the wheels of the integral bridge.

[0028] The sliding thrust rod provided by the embodiment of the present invention has a working structure principle: the sliding thrust rod is installed between the vehicle body and the integral bridge, and the sliding thrust rod starts to work when the wheel rises and falls during driving. The first design scheme: the sliding rod is inserted into the inner pulley group and slides up and down, the U-groove pulley (3) and the sliding rod (1) mutually limit the range of movement, which also limits the position of the transverse center of the vehicle body and the transverse center of the integral bridge, and the bearing seat and the bracket (4) are longitudinally installed, and the main function is to deal with the left-right asymmetric up and down movement of the wheels of the integral bridge. The second design scheme: the outer pulley group (15) slides up and down in the slide rail (11), the slide rail (11) and the outer pulley group (15) mutually limit the range of movement, which also limits the position of the transverse center of the vehicle body and the transverse center of the integral bridge, and the pin rod and the bracket (13) and the rubber bearing bushing (153) of the outer pulley group (15) are longitudinally installed, and the main function is to deal with the left-right asymmetric up and down movement of the wheels of the integral bridge. The working principles of these two design schemes are the same, both of which limit the lateral position of the vehicle body and the integral bridge, but do not affect the up and down movement of the vehicle body and the integral bridge and the left and right asymmetric up and down movement of the wheels. The sliding thrust rod provided by the present invention can improve the comfort and stability of the vehicle with integral bridge suspension during road driving or off-road driving.

[0029] The embodiments described above are part of the embodiments of the present invention, rather than all of the embodiments. The detailed description of the embodiments of the present invention is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
