Problems solved by technology

However, air springs also have technical difficulties that need to be solved. Firstly, because the gas medium is not viscous and is more likely to leak, the design and selection of high-pressure sealing structures under the large load of all air springs is particularly critical. In addition, the cushioning and vibration damping performance under large dynamic and static strokes match also critical

Abstract

The invention relates to an air spring for an electromechanical suspension device. The air spring comprises a cylinder body (2), a piston rod assembly (1) arranged in the cylinder body (2), a rear endcover assembly (7) fixed in the rear end of the cylinder body (2) and connected with the piston rod assembly (1), a front end cover assembly (8) fixedly connected to the cylinder body (2) and the piston rod assembly (1) and an inflation pipe assembly (4) connected with the rear end cover assembly (7). The piston rod assembly (1) is connected with the electromechanical suspension device and used for bearing ground stimulation. According to the air spring, through innovative and optimal design of the structure, the problem about high-pressure sealing under large bearing and the problem about buffer vibration damping performance matching under the large stroke are solved, and the air spring has the advantages of being compact in structure and convenient and reliable to mount and arrange.

Description

technical field [0001] The invention relates to the technical field of vehicle suspension, in particular to an air spring used for an electromechanical suspension device. Background technique [0002] For off-road vehicles, how to obtain good driving comfort under various harsh road conditions has always been the focus of research and development of suspension technology. In order to improve the ride comfort of vehicles, active suspension and semi-active suspension technologies have emerged and been developed. In recent years, with the development of vehicle electric drive technology, motor technology, and electronic control technology, the motor has gradually become the core component of the active suspension actuator. [0003] Electromechanical suspension is an active suspension technology with motor as the core component. It is characterized by the ability to realize mutual conversion between mechanical energy and electrical energy. It is beneficial to improve the off-r...
