Problems solved by technology

The powertrain mount is generally composed of an elastomer material and a variety of metal parts. The elastomer material is mainly natural rubber. Since the main spring and the bumper are made of the same material, the adjustability is poor, and the natural rubber The thermal aging resistance of the rubber is poor, and often cannot meet the thermal aging performance of the impact block; at present, there are also some silicone mounts to improve the thermal aging performance, but the main spring fatigue performance of the silicone mount is poor, and the price is relatively high

Abstract

The invention discloses a multi-elastomer material suspension for a vehicle. The multi-elastomer material suspension for the vehicle is characterized by comprising an outer pipe, an inner pipe and a main spring, wherein one end of the main spring and the inner pipe are vulcanized while the other end of the main spring and the outer pipe are vulcanized; the inner pipe and the main spring divide the outer pipe into a first region and a second region; the outer pipe is provided with at least two collision blocks through vulcanization; the main spring is made of natural rubber; the collision blocks are made of synthetic rubber; and the outer pipe is made of a lightweight material. The multi-elastomer material suspension for the vehicle, disclosed by the invention, has the advantages of not only guaranteeing endurance quality of the main spring, but also satisfying heat-proof aging performance of the collision blocks and greatly improving adjustability of performances.

Description

technical field [0001] The invention relates to a suspension, in particular to a vehicle multi-elastic material suspension. Background technique [0002] In today's society, people have higher and higher requirements for cars, including the comfort and durability of cars. The powertrain suspension system is an important part that affects the comfort of the car, so the requirements of the vehicle manufacturers for the performance of the suspension are getting higher and higher. Each suspension must be guaranteed to be within a certain rigidity range under different working conditions. In order to meet the comfort requirements of the vehicle. Especially for automatic transmission vehicles, there are many kinds of light idling conditions, generally divided into neutral gear, forward gear, reverse gear, and parking gear, and each gear is divided into working conditions with air conditioning on and off. The stress on the mount is different in working conditions, so the perform...
