Novel suspension system metal silencing piece

Abstract

The invention discloses a novel metal silencing piece of a suspension system. The novel metal silencing piece comprises a body. The body is provided with a first through hole, a protrusion and a folded edge. The protrusions are in a curved surface shape and are distributed on the upper side and the lower side of the body, and the folded edge bends and extends towards one side. The protrusions are inserted into connected metal during installation, and the effect of preventing relative sliding is effectively achieved. The folded edge can be mounted in a mounting hole in the connecting metal, so that the effects of positioning and rotation prevention are effectively achieved. The protrusions can be generally arranged to be semicircular protrusions, the axial distance of the protrusions can be increased through the protrusions, axial pressing can be further achieved, gaps can be effectively buffered and reduced through the curved surfaces, and abnormal sound of connection of the suspension system is avoided. The body is made of spring steel, so that the use performance of the device can be improved while the production and manufacturing cost and the process requirement are relatively low.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a novel metal sound-absorbing sheet for a suspension system. Background technique [0002] Nowadays, cars play an indispensable role in people's life and production. In the connection of auto parts, a force transmission connection device is usually required between the frame and the axle, and this force transmission connection device is the suspension. While the car is running, the impact from the road will be transmitted to the body through the suspension system, which will not only easily cause damage to the body, but also cause driving vibration and discomfort. Usually, automobile production will set some elastic devices (such as rubber bushings, polyurethane, etc.) between the suspension system and the body for buffering. [0003] However, the overall cost of these elastic structures is usually relatively high. For some cars with high cost control requirements, the suspension syst...

AI Technical Summary

Problems solved by technology

The general surface of the suspension system parts is electrophoretic paint, which is relatively smooth and has a low friction coefficient. The body mounting surface is also electrophoretic paint, which is relatively smooth and has a low friction coefficient. The coefficient is low, when impacted, the friction resistance of the joint surface cannot resist the impact force, and relative sliding will occur, resulting in abnormal noise
