Embodiment Construction

[0029] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other implementations obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

[0030] see Figure 1-Figure 2 As shown, the present invention provides a kind of automobile buffer block, comprises rubber main spring 1 and spacer 2, and described spacer 2 is installed in the lower part of described rubber main spring 1, and the interior of described rubber main spring 1 is used for installing In the chamber of the casing, the inner and outer walls of the main rubber spring 1 are wave-shaped;

[0031] In addition, the peaks and valleys of th...

Abstract

The invention discloses an automobile buffer block, which comprises a rubber main spring and a spacer. The spacer is arranged on the lower part of the rubber main spring; a chamber for installing a sleeve pipe is arranged in the rubber main spring; an inner wall and an outer wall of the rubber main spring are in wave shapes; and peak points and peak valleys of the wave-shaped inner wall correspondto peak values and peak valley waving positions of the wave-shaped outer wall. The automobile buffer block has the beneficial effects that the buffer block adopts the wave-shaped structure, so that the deformation of the rubber main spring can be effectively limited, the static rigidity is ensured, the compression deformation of a product is reduced, the shear deformation of the product is increased, and the fatigue strength is effectively improved.

Description

technical field [0001] The invention relates to the field of automobile parts, in particular to an automobile buffer block. Background technique [0002] With the improvement of human living standards and the development of the automobile industry, human demand for automobiles has not only been used as a means of transportation, but now it is more concerned about its comfort, that is, NVH performance. As rubber parts on automobiles, its main The function is sealing, dustproof, vibration reduction, buffering, etc. Among them, vibration reduction and buffering are the most important functions and the most direct manifestation of NVH. [0003] As a rubber part for vibration reduction and buffering, the buffer block is generally installed on the longitudinal beam of the vehicle. When the vehicle jumps up and down, it will hit the rear axle for position limitation, buffering and vibration reduction. For this product, both its vibration damping performance and its fatigue perform...
