Abstract

The invention discloses a series-connection-type energy reclaiming hybrid active suspension actuator and a control method thereof. The series-connection-type energy reclaiming hybrid active suspensionactuator comprises an actuator body and an actuator control system. The actuator body comprises a valve-type magnetorheological damper mechanism and a power transmission mechanism; the valve-type magnetorheological damper mechanism comprises a liquid storage cylinder barrel, a working cylinder barrel, a sealing end cover, a piston rod, a piston, a stretching adjusting valve, a circulating valve,magnetorheological liquid, a compression adjusting valve, a compensation valve, a guiding seat and an oil seal; the power transmission mechanism comprises a motor mounting seat, a direct-current brushless motor, a ball lead screw, a ball lead screw nut and a sleeve; and the actuator control system comprises an actuator controller and an electric energy storage circuit. The control method of the series-connection-type energy reclaiming hybrid active suspension actuator comprises the steps of firstly, data collection and synchronous transmission, and secondly, data analysis processing and controlling. The design is novel and reasonable, and implementing is convenient; better damping can be achieved, and sufficient electric energy consumed during energy reclaiming can further be generated; and using is convenient, the using prospects are wide, and using and popularizing are facilitated.

Description

technical field [0001] The invention belongs to the technical field of vehicle vibration damping devices, and in particular relates to a serial energy-feeding hybrid active suspension actuator and a control method thereof. Background technique [0002] Suspension system is an important part of a car. Its main function is to carry the body and attenuate the vibration of the body. It determines the ride comfort and handling stability of the vehicle. Most of the current automobile suspensions are passive suspensions, but the fixed structural parameters of passive suspensions are difficult to adapt to changing driving conditions. Active suspension uses controllable actuators to change the stiffness and damping of the suspension in real time according to road conditions to improve the ride comfort and handling stability of the vehicle. However, the active suspension consumes a certain amount of energy and reduces the fuel economy of the vehicle. . [0003] The energy-feeding ac...
