Abstract

The invention discloses a combined energy feedback type semi-active suspension fork actuator and a control method thereof. The combined energy feedback type semi-active suspension fork actuator comprises an actuator body and a monitoring device, wherein the actuator body comprises an air spring mechanism and a linear motor; the air spring mechanism comprises an air spring, an air spring upper endcover and an air spring lower end cover; the linear motor comprises a secondary permanent magnet assembly and a primary coil assembly; the secondary permanent magnet assembly comprises a linear motorsecondary housing and a secondary permanent magnet. The control method comprises the following steps of I, performing data acquisition and synchronous transmission; II, adjusting the height differenceof spring mass and non-spring mass in the starting stage of a vehicle; III, adjusting the height difference of the spring mass and the non-spring mass in the travelling stage of the vehicle and electromagnetic damping force; and IV, after the vehicle stops travelling, adjusting the height difference of the spring mass and the non-spring mass. Through the adoption of the combined energy feedback type semi-active suspension fork actuator disclosed by the invention, the stability and the smoothness of the vehicle can be improved; and energy generated by the actuator is recovered, and the energyconsumption of the vehicle is reduced.

Description

technical field [0001] The invention belongs to the technical field of automobile suspension systems, and in particular relates to a composite energy-feeding semi-active suspension actuator and a control method thereof. Background technique [0002] When the vehicle is running, the vehicle vibrates due to the excitation of the unevenness of the road surface. At present, what is widely used in automobiles is to realize the functions of damping vibration and carrying the body through passive suspension (composed of shock absorbers, elastic elements, etc.). However, the performance parameters (stiffness and damping) of the passive suspension cannot be adjusted in real time according to the actual working conditions of the vehicle during driving. The frame converts the energy of the vibration of the car into heat energy and dissipates it in the air through the shock absorber and the elastic element, and it is not utilized. Due to the shortcomings of the passive suspension that...
