Abstract
The utility model provides a kind of novel rear torsion beam bushing with knurling structure, including beam bush body, the beam bush body includes bushing skeleton, vulcanization of rubber skeleton, rubber bushing and bushing sleeves, socket assembly from outside to inside, the bushing sleeves end face are equipped with rotation preventing mechanism to bushing skeleton, vulcanization of rubber skeleton, rubber bushing and the bushing sleeves successively.The rotation preventing mechanism is knurling structure, and the bushing sleeves generally cylindrical tubular structure, the knurling structure is arranged on a side end face of bushing sleeves, and knurling structure is an integral structure with bushing sleeves.This product improves the compactness that bushing sleeves are combined with mounting bracket, reduces torsion beam hopping process and generates abnormal sound noise, while also improving bushing service life to a certain extent.
Description
Technical field
The utility model is related to passenger car torsion beam suspension trailing arm bushing, more particularly to after a kind of novel with knurling structure
Torsion beam bushing.
Background technology
Currently, torsion beam trailing arm bushing end is planar structure at present, structure has the following disadvantages:Torsion beam is jumped up and down
Bushing sleeves end face is easy to generate relative motion with holder during dynamic, forms abnormal sound noise, while making the service life of bushing significantly
It reduces, so needing a kind of novel rear torsion beam bushing with knurling structure that can just solve these problems.
Utility model content
Insufficient in view of the prior art, the utility model provides a kind of novel rear torsion beam bushing with knurling structure.
To achieve the goals above, technical solution adopted in the utility model is:After a kind of novel with knurling structure
Torsion beam bushing, including beam bush body, the beam bush body include bushing skeleton, vulcanization of rubber skeleton, rubber bushing
And bushing sleeves, the set tipping from outside to inside successively of the bushing skeleton, vulcanization of rubber skeleton, rubber bushing and bushing sleeves
Match, the bushing sleeves end face is equipped with rotation preventing mechanism.
The rotation preventing mechanism is knurling structure, and the bushing sleeves generally cylindrical tubular structure is described
Knurling structure is arranged on a side end face of bushing sleeves, and knurling structure is an integral structure with bushing sleeves.
The knurling structure is that several double wedges are formed by center of circle annular array of the axle center of bushing sleeves.
It is wide that one end width of the double wedge close to bushing sleeves axle center is less than the one end of double wedge far from bushing sleeves axle center
Degree.
The beneficial effects of the utility model:The utility model provides a kind of novel rear torsion beam bushing with knurling structure,
This product improves the compactness that bushing sleeves are combined with mounting bracket, reduces torsion beam hopping process and generates abnormal sound noise,
Bushing service life is also improved to a certain extent simultaneously.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model;
Fig. 2 is the structural decomposition diagram of the utility model.
Specific implementation mode
As Figure 1-Figure 2, a kind of novel rear torsion beam bushing with knurling structure, including beam bush body, it is described
Beam bush body includes bushing skeleton 1, vulcanization of rubber skeleton 2, rubber bushing 3 and bushing sleeves 4, the bushing skeleton 1, rubber
Glue vulcanizes skeleton 2, rubber bushing 3 and bushing sleeves 4, and socket assembly, 4 end face of bushing sleeves are set from outside to inside successively
There is rotation preventing mechanism.
The rotation preventing mechanism is knurling structure 5, and the generally cylindrical tubular structure of bushing sleeves 4 is described
Knurling structure 5 be arranged on a side end face of bushing sleeves 4, and knurling structure 5 is an integral structure with bushing sleeves 1.Institute
The knurling structure 5 stated is that several double wedges are formed by center of circle annular array of the axle center of bushing sleeves 4.The double wedge is close to bushing
One end width in 4 axle center of casing is less than one end width of the double wedge far from 4 axle center of bushing sleeves;This structure makes torsion beam move up and down
Bushing sleeves end face is with bushing mounting bracket without relative motion in the process, and the combination of bushing sleeves end face and bushing mounting bracket is more
Step up close, reduces the abnormal sound noise generated in torsion beam hopping process significantly.
This structure indirectly improves making for bushing and holder by eliminating the relative motion of bushing and bushing mounting bracket
With the service life, reduction is lost after sale.
The operation principle of this product, bushing sleeves end face are knurling structure, can make annular knurl when with bushing support assorted
Embedded holder inner panel, increases clamping force, to prevent bushing from rotating.
The beneficial effects of the utility model:The utility model provides a kind of novel rear torsion beam bushing with knurling structure,
This product improves the compactness that bushing sleeves are combined with mounting bracket, reduces torsion beam hopping process and generates abnormal sound noise,
Bushing service life is also improved to a certain extent simultaneously.
