Description

Technical Field

[0001] The present invention relates to the technical field related to automobile chassis, and in particular to an automobile chassis bushing structure. Background Art

[0002] As competition in the automotive market becomes increasingly fierce, users' expectations and requirements for vehicle driving performance are also increasing. The comfort and handling stability of the chassis system play a vital role in the entire vehicle's driving process. When a vehicle is driving on various road surfaces, the chassis suspension system plays an important role in buffering and reducing vibration excitation caused by uneven road surfaces, thereby improving the user's riding comfort and handling stability.

[0003] In modern automobile suspension systems, chassis bushings have become an indispensable and important component of chassis systems due to their excellent elastic properties and vibration isolation performance. However, there are still some problems with the current chassis bushings used in automobile chassis suspension links on the market. In the guide devices of the suspension system (such as swing arms, rear axles, etc.), rubber bushings are increasingly used at the hinge points connecting the vehicle body. However, most of the existing rubber bushing connection structures have the disadvantages of complex structures and complicated processes. At the same time, when used in existing automobile suspension systems, the overall suspension buffering effect is poor, thereby reducing the practicality of the overall device.

[0004] Therefore, based on the above problems, the present invention provides an automobile chassis bushing structure. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides an automobile chassis bushing structure, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] A car chassis bushing structure comprises two bushing kits, a mating connector is installed between the two bushing kits, a mounting frame is fixedly provided on one side of each bushing kit, a chassis frame is provided on one side of the two mounting frames, a plurality of U-shaped connecting blocks are fixedly provided on one side of the chassis frame, a mounting shaft is installed in each U-shaped connecting block, a hinge sleeve is movably sleeved on each mounting shaft, each hinge sleeve is fixedly connected to the corresponding mounting frame, two first buffer members are installed between the chassis frame and the mounting frame located below, a second buffer member is provided between the two first buffer members, and the second buffer member is installed between the chassis frame and the mounting frame located below.

[0008] Furthermore, the mating connector includes a connecting tube, a mounting shaft is installed in the connecting tube, a wheel is installed on the mounting shaft, two special-shaped connecting rods are fixed on the connecting tube, and mounting ball heads are fixed on the opposite ends of the two special-shaped connecting rods, and each mounting ball head is installed in the corresponding bushing kit.

[0009] Furthermore, the bushing assembly consists of a second bushing sleeve and a first bushing sleeve, the first bushing sleeve is arranged in the second bushing sleeve, and a buffer connection is provided between the second bushing sleeve and the first bushing sleeve through the vulcanization action of the rubber injection machine, and a circular hinge groove is opened on the first bushing sleeve, and the mounting ball head is movably hinged in the circular hinge groove.

[0010] Furthermore, the buffer connection is made of rubber.

[0011] Furthermore, the first buffer member includes two first U-shaped blocks, which are respectively fixed to the chassis frame and the mounting frame located below. A hinge block is movably hinged inside each of the first U-shaped blocks, and a mounting tube and a piston rod are respectively fixed on the opposite surfaces of the two hinge blocks. The piston rod is slidably arranged on the mounting tube.

[0012] Furthermore, both the mounting tube and the piston rod are fixedly sleeved with a limiting ring, a first buffer spring is provided between the two limiting rings, and the first buffer spring is sleeved on the mounting tube and the piston rod.

[0013] Furthermore, a piston head is fixedly provided on one end of the piston rod located in the mounting cylinder.

A mounting ring is fixed on each of the hinge plates, and a second buffer spring is arranged between the two mounting rings. The second buffer spring is sleeved on the two guide pins.

[0015] The present invention provides an automobile chassis bushing structure. Compared with the prior art, it has the following beneficial effects:

[0016] 1. The present invention improves the configuration of the lining assembly. The automobile chassis lining assembly connects the second lining sleeve, the first lining sleeve, and the buffer connector (made of rubber) through the vulcanization action of a rubber injection machine. (The buffer connector adopts a reduced-diameter symmetrical structure, which can effectively attenuate the vibration generated by the automobile chassis.) The internal stress of the product is then eliminated through the diameter reduction process. When the vehicle is started or on bumpy roads, the automobile chassis lining assembly relies on the buffer connector in the lining to effectively attenuate the vibration generated by the automobile powertrain.

[0017] 2. The present invention cooperates with the first buffer member, the second buffer member and other structures. When the wheel moves or encounters bumpy road conditions, the cooperation of the two first buffer members, the second buffer members and the four hinge points between the two mounting brackets and the chassis frame can achieve a good buffering effect, further increase the buffering and shock absorption performance of the overall device, and improve the practicality of the overall device.
