Detailed Description

The multifunctional swing arm bushing structure of the present invention will be further described below with reference to specific embodiments to help those skilled in the art to understand the concept and technical solution of the present invention more completely, accurately and deeply.

Example 1

In order to solve the problem of space shortage in arrangement on the auxiliary frame, the mounting point of the stabilizer bar is adjusted on the shell of the swing arm bushing. The embodiment provides a multifunctional swing arm lining structure which can be independently disassembled, can meet the whole vehicle performance adjustment requirement and has large design space. The multi-functional swing arm bush structure of this embodiment makes the design of bush body not receive sub vehicle frame space restriction, is fixed in the sub vehicle frame outside, can design stabilizer bar mounting point on the bush shell body simultaneously.

Specifically, as shown in fig. 1 to 5, the multifunctional swing arm bushing structure of the present embodiment includes a swing arm body 61 and a bushing assembly 62, the bushing assembly 62 includes a bushing outer shell 22 and a mounting sleeve 23 coaxially disposed, the bushing outer shell 22 is located outside the mounting sleeve 23, a damping rubber 21 is disposed between the bushing outer shell 22 and the mounting sleeve 23, and a central hole 14 is disposed in the mounting sleeve 23. The swing arm body 61 and the bushing assembly 62 are connected by a fixing bolt 71 passing through the center hole 14 of the swing arm body 61 and the bushing assembly 62 and fastened by a nut 72.

The swing arm body 61 and the lining assembly 62 in the lining structure of the embodiment can meet the assembly requirement through simple screw connection, and during assembly, the lining assembly 62 penetrates through the fixing bolt 71 of the swing arm body, and then the fixing nut 72 is installed to complete assembly. As shown in fig. 4-5, the bushing assembly structure of this embodiment integrates the associated mounting holes in the bushing outer housing 22. The outer wall of the bushing outer shell 22 is provided with a first assembling plate, and the first assembling plate is provided with a first mounting hole 11 for fixing with a vehicle body. Be provided with on the outer wall of bush shell body 22 and be used for the second assembly plate of being connected with sub vehicle frame and stabilizer bar, be provided with on the second assembly plate and be used for with sub vehicle frame fixed third mounting hole 13 and be used for the second mounting hole 12 of fixed stabilizer bar, it has the internal thread to process in the second mounting hole. The first assembly plate, the second assembly plate and the liner housing shell 22 are of unitary construction (formed by one casting). As shown in fig. 6 to 8, the bushing outer housing 22 is screwed with the sub-frame 33 by a bolt 52 passing through the third mounting hole 13 and fixed by a nut 51, thereby determining the mounting position of the swing arm assembly 31. The stabilizer bar 32 is fixed to the second mounting plate by a clip 42 and fastened by a fixing bolt 41 passing through the second mounting hole 12, and the stabilizer bar is fixed without a nut since a screw is processed in the second mounting hole 12.

The swing arm assembly structure of this embodiment directly fixes stabilizer bar 32 on bushing shell body 22, has reduced the part quantity that needs to fix on sub vehicle frame 33, moves stabilizer bar 32 fixed point to the car outward simultaneously, can effectual increase stabilizer bar 32 torsional rigidity contribution, has bigger help to vehicle performance timing. The swing arm assembly 31 and the lining assembly 62 are fixed in a threaded manner, when the chassis is adjusted, only the lining assemblies 62 with different rigidity need to be provided, the swing arm body 61 is unchanged, the development cost is reduced, and meanwhile, parts are more convenient and faster to replace when the chassis is adjusted. The problem of the swing arm assembly of different bush rigidity need frequently be changed when the chassis performance is proofreaied and correct is solved, simultaneously because the swing arm bush independently installs in the sub vehicle frame outside, do not receive sub vehicle frame space restriction, can freely design the bush size, the bush rigidity control range is bigger like this.

For those skilled in the art, the specific embodiments are only exemplary descriptions of the present invention, and it is obvious that the present invention is not limited to the above-mentioned embodiments, and various insubstantial modifications can be made without modification to the method concept and technical solution of the present invention, and the present invention is also within the scope of the present invention.
