Problems solved by technology

[0003] The existing suspension bushing, such as the patent of CN 203413009 U, includes a housing, a core tube located in the housing and a shock-absorbing layer between the housing and the core tube, the housing and the shock-absorbing Between the layers, the core tube and the shock absorbing layer are all fixed by the fitting connection of the tenon and the tenon. Although it improves its own performance, the suspension bush with this structure is installed on the bush installation When seated, the shock-absorbing layer is easy to come out, that is, the anti-pressure and detachment force of the shell is insufficient

Embodiment 1

[0021] Such as figure 1 and figure 2 The shown automobile suspension bushing comprises a housing 1 and a shock absorbing layer, the outer wall of the shock absorbing layer is provided with a tongue and groove, and the inner wall of the housing 1 is provided with a groove matching the tongue and groove. The tenon 2, one end of the inner wall of the housing 1 is provided with an anti-off protrusion 3, and the tenon 2 is provided with a one-way tooth 21 that enables the shock-absorbing layer to move only in the direction of the anti-off protrusion 3, Tooth grooves matching the one-way teeth 21 are provided in the mortise and groove.

[0022] In this embodiment, only one end of the inner wall of the housing is provided with an anti-off protrusion, which is convenient for the installation of the shock-absorbing layer; The installation of the seismic layer, so only one end of the inner wall of the housing is provided with an anti-off protrusion. However, only one end is provided...

Embodiment 2

[0024] Such as figure 1 The shown a kind of automobile suspension bushing, this embodiment refines the anti-loosening protrusion on the basis of embodiment 1, that is, discloses a realization method thereof in detail, and the anti-loosening protrusion 3 is Convex ring.

Embodiment 3

[0026] Such as figure 2 Shown is a kind of automobile suspension bushing, this embodiment refines the anti-loosening protrusion on the basis of embodiment 1, that is, discloses another implementation method in detail, the anti-loosening protrusion 3 For the block.

[0027] There are at least two blocks.

[0028] Compared with the method of using the convex ring in Embodiment 2, the method of using the clamping block can save materials and cost.

Abstract

The invention discloses an automotive suspension bushing which comprises a shell and a shock absorption layer, wherein a mortise is formed in the outer wall of the shock absorption layer; a tenon matched with the mortise is arranged on the inner wall of the shell; a falling prevention bulge is arranged at one end of the inner wall of the shell; a one-way tooth capable of enabling the shock absorption layer to only move towards the falling prevention bulge is arranged on the tenon; a tooth groove matched with the one-way tooth is arranged in the mortise. The automotive suspension bushing is simple in structure, and the shock absorption layer has a low possibility of falling off.

Description

technical field [0001] The invention relates to the technical field of automobiles, and more specifically relates to an automobile suspension bushing. Background technique [0002] The suspension positioning parameters of the car under various actual operating conditions will change, which will not be conducive to the differential handling and driving stability, and will also affect the ride comfort. In order to solve these problems of the suspension system, the suspension system Generally, the bushing structure is used in the vehicle, which can avoid the mutual movement interference of the suspension components caused by the rigid connection, and can also attenuate and buffer the impact and vibration from the ground, so as to achieve a balance between handling stability and ride comfort. [0003] Existing suspension bushings, such as the patent with the authorized announcement number: CN 203413009 U, include a housing, a core tube located in the housing and a shock-absorbin...
