Specific embodiment
Fig. 1 be according to one embodiment of this utility model a kind of can the effective torsion beam rear axle bushing of loss of weight schematic
Perspective view.
As shown in figure 1, a kind of bushing for torsion beam rear axle, including bushing inner tube 1, bushing outer tube 2 and rubber bodies 3,
Described rubber bodies 3 are arranged between described bushing inner tube 1 and described bushing outer tube 2, and described bushing outer tube 2 one end is provided with flange
It is characterised in that described bushing inner tube 1 is provided centrally with through-core hole 11, described through-core hole 11 includes endoporus 12 and along interior to structure
Multiple lightening grooves 13 of the circumferential edge setting in hole 12, described endoporus 12 is communicated with described lightening grooves 13.
The scheme that therefore endoporus 12 of the present embodiment and lightening grooves 13 communicate can more effectively utilize the space of bushing inner tube 1
Carry out light-weight design, reach the purpose of the structure optimization of effective loss of weight, reduce the material of bushing inner tube simultaneously, reduce lining
The purpose of set inner tube 1 cost.
Described lightening grooves 13 are petal shape.The cross sectional shape of described through-core hole 11 is quincunx.Described lightening grooves 13
Quantity is five.
The symmetrical structure of the therefore endoporus 12 of the present embodiment and lightening grooves 13 combination balances being subject to of bushing inner tube 1 effectively
Power, ensure that the bushing inner tube 1 after loss of weight operationally has enough rigidity and intensity, simultaneously through-core hole 11 forming operation
Positioning is convenient, simple to operate.
Described rubber bodies 3 arrange rubber bodies turnup structure in described bushing outer tube 2 flange one end.Described rubber bodies flange knot
Three breach 31 are provided with structure.
