Abstract
The utility model discloses an automobile auxiliary frame bushing which is characterized in that: the auxiliary frame comprises an outer supporting pipe and an inner supporting pipe, wherein the inner supporting pipe is arranged in the outer supporting pipe, the bottom of the outer supporting pipe is provided with a skirt edge used for limiting displacement of a lining on an auxiliary frame, a rubber damping layer used for buffering is arranged between the outer supporting pipe and the inner supporting pipe, the rubber damping layer is provided with a gasket wrapping the skirt edge, and a plurality of oval through holes used for increasing rigidity characteristics of the lining are formed in the rubber damping layer. The utility model has the beneficial effects that: in order to increase the damping effect of the bushing, the size of the bushing is increased, similarly, the thickness of the rubber damping layer is increased, and the hardness after integral vulcanization treatment is increased, so that the elliptical through hole is designed in the rubber damping layer, the rigidity characteristic of the bushing is increased, the heat dissipation and cost saving effects are achieved, and the hardness of the rubber layer is not increased.
Description
Technical Field
The utility model relates to an automobile auxiliary frame bushing, and belongs to the field of automobile parts.
Background
With the improvement of the living standard of people, more and more attention is paid to the comfort performance of vehicles in running. The sub vehicle frame carries out the flexible buffer through bush and automobile body and is connected, can effectively reduce the vibrations that transmit the automobile body, improves the travelling comfort. The automobile bushing is formed by integrally vulcanizing a metal outer pipe, a metal inner pipe and a rubber layer positioned between the metal outer pipe and the metal inner pipe. As the demand for shock absorption between the subframe and the vehicle body increases, the larger the subframe bushing becomes. With the increase of the bush, the metal pipe is also continuously increased, the rubber layer needs to keep a certain thickness to meet the requirement of rigidity performance, if the rubber layer is too thick, the rubber with very high hardness needs to be used to meet the requirement of rigidity performance, and the cost is increased.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects in the prior art, the utility model provides the automobile auxiliary frame bushing, which not only solves the problem of insufficient rigidity of the bushing, but also solves the problem that a bushing rubber layer is hardened in order to meet the requirement of rigidity thickening.
In order to achieve the purpose, the technical scheme of the utility model is as follows: the auxiliary frame comprises an outer supporting pipe and an inner supporting pipe, wherein the inner supporting pipe is arranged in the outer supporting pipe, the bottom of the outer supporting pipe is provided with a skirt edge used for limiting displacement of a lining on an auxiliary frame, a rubber damping layer used for buffering is arranged between the outer supporting pipe and the inner supporting pipe, the rubber damping layer is provided with a gasket wrapping the skirt edge, and a plurality of oval through holes used for increasing rigidity characteristics of the lining are formed in the rubber damping layer.
Furthermore, the gasket is provided with a plurality of installation caulking grooves, and a plurality of small anti-skidding salient points are uniformly arranged on the gasket.
Furthermore, the outer pipe wall of the inner supporting pipe is provided with a hanging table for attaching the rubber damping layer.
The utility model has the beneficial effects that: in order to increase the damping effect of the bushing, the size of the bushing is increased, the thickness of the rubber damping layer is increased, the hardness of the rubber damping layer after integral vulcanization treatment is increased, and therefore the oval through hole is designed in the rubber damping layer, the rigidity characteristic of the bushing is increased, the heat dissipation effect and the cost saving effect are achieved, and the hardness of the rubber layer does not need to be increased.

Detailed Description
The present invention will be described in further detail with reference to the following embodiments and the accompanying drawings.
As shown in figures 1 and 2, the utility model discloses an automobile subframe bushing, which comprises an outer supporting pipe 1 and an inner supporting pipe 2, wherein the inner supporting pipe 2 is made of 20-steel quenching materials, the outer supporting pipe 1 is made of hot rolled steel plates, the bushing is installed at the joint of a subframe and a frame, and the inner supporting pipe 2 penetrates through an installation shaft to be fixed. The inner supporting tube 2 is arranged in the outer supporting tube 1, the bottom of the outer supporting tube 1 is provided with a skirt edge 3 used for limiting displacement of the lining on the auxiliary frame, a rubber damping layer 4 used for buffering is arranged between the outer supporting tube 1 and the inner supporting tube 2, the rubber damping layer 4 is provided with a gasket 5 wrapping the skirt edge 3, and the whole frame is further subjected to damping treatment. Be provided with the oval-shaped through-hole 6 that the several is used for increasing bush rigidity characteristic in the rubber shock absorber layer 4, increase through-hole 6 promptly and increase its rubber shock absorber layer 4's deformation and resilience, guarantee the shock attenuation effect of bush, oval minor axis is the radial deformation for the convenience bush with the radial the same of bush, and makes things convenient for the interference fit of bush, and still plays the effect of louvre in practical application.
The gasket 5 is provided with a plurality of mounting caulking grooves 7 for increasing the torque load of the bushing, and a plurality of small convex points 8 for preventing skidding are uniformly arranged on the gasket 5.
The outer pipe wall of the inner supporting pipe 2 is provided with a hanging platform 9 for attaching the rubber shock absorption layer 4.
The technical solutions provided by the embodiments of the present invention are described in detail above, and the principles and embodiments of the present invention are explained herein by using specific examples, and the descriptions of the embodiments are only used to help understanding the principles of the embodiments of the present invention; meanwhile, for a person skilled in the art, according to the embodiments of the present invention, there may be variations in the specific implementation manners and application ranges, and in summary, the content of the present description should not be construed as a limitation to the present invention.
