Abstract
The utility model discloses an aluminum alloy semi-trailer suspension which comprises a front support, a middle support, a rear support, a balance swing arm and a steel plate spring. The front support, the middle support and the rear support are integrally-formed aluminum alloy supports. As integrally-formed aluminum alloy structures are adopted in the front support, the middle support and the rear support, the aluminum alloy semi-trailer suspension can be directly welded to an aluminum alloy longitudinal beam of a semi-trailer, and therefore the problem that the connection difficulty of a traditional steel plate suspension and the aluminum alloy longitudinal beam is large is solved; wear-resistant parts are arranged in the front support, the rear support and the balance swing arm, and therefore connection of the front support, the balance swing arm and the rear support and the steel plate spring is achieved, and the aluminum alloy semi-trailer suspension has the advantages of being light in weight and convenient to maintain.
