Auxiliary rubber metal stacking spring for truck and mounting method thereof

Abstract

The invention provides an auxiliary rubber-metal leaf spring used in a cargo truck and an installation method thereof. The auxiliary rubber-metal leaf spring is a composite elastic rubber-metal body which adopts a leaf rubber-metal spring structure, and is combined by a plurality of elastic rubber layers and metal spacers, and the elastic rubber layers and the metal spacers are arranged by adopting a conical structure, which is an elastic body combination with unequal elasticity; the elastic rubber layers can be 2 to 9 rubber layers, and the metal spacers can be 3 to 9 layers; a layer of nylon plate is attached on the top layer of the composite elastic rubber metal body, and is on the top end of the auxiliary rubber-metal leaf spring. The auxiliary rubber-metal spring is reversely vertically arranged on a truck frame through a bolt, and maintains a certain clearance with an axle when the truck is in idle load. When the cargo truck does not have goods, the auxiliary rubber-metal leaf spring is not contacted with the axle; when load increases, the nylon plate of the auxiliary rubber-metal leaf spring starts to be contacted with the axle to play a role in decreasing vibration.

Description

technical field [0001] The invention relates to a damping component for a truck rubber suspension and an installation method thereof, in particular to an auxiliary rubber elastic component for a truck rubber suspension and an installation method thereof. It is mainly used for the vibration reduction of the rubber suspension of the truck and bears the vertical load. Background technique [0002] The damping device of modern automobiles has been transformed from the original leaf spring to the elastic element of rubber metal structure. The so-called automobile rubber suspension is one of them. The automobile rubber suspension has been widely used abroad, but it is still in its infancy in my country. Automotive rubber suspensions have significant advantages over traditional leaf springs. When using the traditional leaf spring structure, once the leaf spring is damaged, the whole vehicle cannot be driven and can only be replaced with a new leaf spring. For a vehicle equipped ...

AI Technical Summary

Problems solved by technology

However, due to the difference between China's road surface and the carrying capacity of heavy-duty vehicles compared with foreign countries, the original rubber suspension is not used well in China, and the service life of the auxiliary spring is greatly reduced, and defects such as cracks will appear after about 10,000km , while the customer requires 200,000km maintenance-free

Therefore, foreign products cannot meet the needs of our domestic automobiles
