Electromechanical suspension device based on torsion rod spring

Abstract

The invention relates to an electromechanical suspension device based on a torsion rod spring. The electromechanical suspension device comprises a balanced elbow torsion rod assembly (1), a connectingrod assembly (2) and an electromechanical actuator assembly (3) which are sequentially and movably connected; the balanced elbow torsion rod assembly (1) is connected with a bogie wheel (130) to beara static load and a dynamic load of a vehicle body (110), and vibration is buffered; and the loads are transmitted to the electromechanical actuator assembly (3) through the connecting rod assembly (2). According to the suspension device, the electromechanical actuator assembly (3) and the balanced elbow torsion rod assembly (1) are arranged in parallel, the characteristics of compact structure and modular design are achieved, and the recovery efficiency of vibration energy is greatly improved.

Description

technical field [0001] The invention relates to the technical field of vehicle suspension, in particular to an electromechanical suspension device based on torsion bar springs. 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, and the integrated structure of the motor and reducer is applied to the suspension system, which can realize the suspension active or semi-active control. However, the mutual conversion efficiency between mechanical energy and electric energy of the e...

Problems solved by technology

However, the mutual conversion efficiency between mechanical energy and electric energy of the electromechanical suspension is not high, which reduces the ride comfort of the vehicle and the off-road driving speed of the vehicle; Under such circumstances, the control of the motor drive by the controller to control the power generation capacity is not obvious, which leads to the incomplete function of the semi-active suspension and affects its energy recovery.
