Steel suspension is our common steel plate spring, and the full name is a series of stringed steel plates to balance suspension. It is mainly composed of steel plate spring, suspension support (commonly known as hanging ear), link rod, U -shaped bolt and other parts. The vertical force of the body falls directly on a shaft. The biggest advantage of this suspension is cheap, good reliability, and convenient maintenance. At present, more than 80%of ordinary semi -semi -trailers use steel plate spring balance suspension.
