Problems solved by technology

[0003] The existing bushing structure mainly focuses on improving the torsional durability and preventing the bushing from aging and cracking. However, due to the increase in the friction coefficient of rubber products in the case of high humidity or long-term use of the vehicle, rubber bushes and The relative frictional force generated by the rotation of the metal parts becomes larger, causing the car to produce a "quack" sound due to the frictional force, resulting in abnormal frictional noise, which increases the noise of the whole vehicle. Therefore, the application provides an anti-abnormal noise High Temperature Mechanical Bushings to Meet Demand

Abstract

The invention relates to the technical field of abnormal sound prevention and high temperature resistance of mechanical bushings, and discloses an abnormal sound prevention and high temperature resistance mechanical bushing which comprises a first outer sleeve, a second outer sleeve fixedly connected into the first outer sleeve, a rubber sleeve fixedly connected into the second outer sleeve, and an inner sleeve fixedly connected into the rubber sleeve; an inner sleeve column is fixedly connected into the inner sleeve, mounting bases are fixedly connected to the two sides of the inner sleeve column correspondingly, four first buffer holes are formed in one side of the rubber sleeve, a second buffer hole, a third buffer hole and a fourth buffer hole are formed in one side of the rubber sleeve, and annular ribs which are transversely arranged are fixedly connected to the inner wall of the second buffer hole; transverse reinforcing ribs are fixedly connected to the inner walls of the two third buffer holes, and reinforcing bags are fixedly connected to the inner walls of one sides of the two third buffer holes. The motor is reasonable in structure, convenient to assemble, excellent inperformance and capable of resisting high temperature and preventing abnormal sounds in the using process.

Description

technical field [0001] The invention relates to the technical field of outdoor projection fixed installation boxes, in particular to an abnormal noise-proof and high-temperature-resistant mechanical bushing. Background technique [0002] With the rapid growth of automobile users, the user group has higher and higher requirements for the quality of the car's abnormal noise. As a common part in the chassis suspension system, bushings have higher and higher requirements for preventing abnormal noise. The main structure of the bushing in the suspension system of the car is natural rubber or additives such as anti-aging, in order to achieve some special properties of the bushing. [0003] The existing bushing structure mainly focuses on improving the torsional durability and preventing the bushing from aging and cracking. However, due to the high humidity in the weather or the long-term use of the vehicle, the friction coefficient of rubber products increases, and the rubber bush...
