Problems solved by technology

At present, the rear suspension system of some small special-purpose vehicles and some off-highway vehicles in the society adopts a suspension system combining leaf springs and shock absorbers. Due to the small market size of these two types of vehicles, the investment in research and development is small, and the resources for research and development are insufficient. Sufficiently, the scale of enterprises engaged in manufacturing in this area is average, so restricted by the number and level of professional designers in this area, the comfort and handling stability of the designed suspensions of these two types of vehicles cannot meet the requirements of laws, regulations and customers.

Abstract

The invention relates to the technical field of automobile chassis suspensions and belongs to an automobile chassis traveling system. The problems existing in the comfort level and the control stability of rear suspension systems of part of small special vehicles and part of non-road vehicles in society are mainly solved. The automobile composite suspension system comprises a plate spring, a spiral spring and a plate spring lifting lug. A plate spring front end is connected with an automobile frame, a plate spring rear end is connected with the plate spring lifting lug, the plate spring lifting lug is connected with the automobile frame, the middle portion of the plate spring is connected with an axle, a spiral spring upper end is connected with the automobile frame, and a spiral spring lower end is connected with the axle. An automobile composite suspension system meets the requirements for the taking comfort level and the control stability of part of the small special vehicles and part of the non-road vehicles, the process is simple, and the performance is reliable.

Description

technical field [0001] The invention relates to the technical field of automobile chassis suspension and belongs to the automobile chassis driving system. Background technique [0002] According to the different functional requirements of automobiles, automobile suspensions have various structures and forms. The mainstream components for vibration reduction and buffering include leaf springs, coil springs, oil-gas springs, air springs, torsion bar springs, etc. At present, the rear suspension system of some small special-purpose vehicles and some off-highway vehicles in the society adopts a suspension system combining leaf springs and shock absorbers. Due to the small market size of these two types of vehicles, the investment in research and development is small, and the resources for research and development are insufficient. Sufficiently, the scale of enterprises engaged in manufacturing in this area is average, so restricted by the number and level of professional designe...
