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), and a piston rod assembly (1) fixed in the cylinder body (2). A rear end cover assembly (7) in the rear end of the cylinder block (2) and connected with the piston rod assembly (1), and a rear end cover assembly (7) fixedly connected to the cylinder block (2) and the piston rod assembly (1) The front end cover assembly (8) and the gas tube assembly (4) connected with the rear end cover assembly (7); the piston rod assembly (1) is connected with the electromechanical suspension device, using to carry ground excitation. The air spring provided by the invention solves the problem of high pressure sealing under large load and the matching problem of buffer vibration damping performance under large stroke through structural innovation and optimization design, and has the characteristics of compact structure, convenient and reliable installation and arrangement.

Description

technical field [0001] The present invention relates to the technical field of vehicle suspension, in particular to an air spring for an electromechanical suspension device. Background technique [0002] For off-road vehicles, how to obtain a good ride comfort in various harsh road conditions has always been the focus of the 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 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 a motor as the core component. Its characteristic is that it can realize the mutual conversion of mechanical energy and electrical energy, which is suitable for the development trend...
