Electromagnetic-viscosity energy consumption combined type vibration reduction device for vehicle and control method

Abstract

The invention provides an electromagnetic-viscosity energy consumption combined type vibration reduction device for a vehicle and a control method. The electromagnetic-viscosity energy consumption combined type vibration reduction device for the vehicle comprises a viscous energy consumption device, a vibration reduction spring and a magnetic vibration reduction cylinder, wherein the viscous energy consumption device and the damping spring which is arranged on the outer side of the viscous energy consumption device are connected with the magnetic vibration reduction cylinder in series, the viscous energy consumption device is connected with a vehicle main control oil way so as to control the stroke of the viscous energy consumption device, the magnetic vibration reduction cylinder is connected with a vehicle main control circuit, and therefore the hardness of the magnetic vibration reduction cylinder is controlled. According to the electromagnetic-viscosity energy consumption combinedtype vibration reduction device for the vehicle and the control method, the length of the whole vibration reduction device can be controlled by controlling the amount of damping oil in the viscous energy consumption device, and the hardness of the magnetic vibration reduction cylinder can be controlled by controlling the current of the magnetic vibration reduction cylinder, so that the purpose ofadjusting the performance of the vibration reduction device according to the using environment is achieved.

Description

technical field [0001] The invention belongs to the technical field of vehicle vibration damping devices, and in particular relates to a vehicle electromagnetic-viscosity energy consumption combined vibration damping device and a control method. Background technique [0002] In order to quickly attenuate the vibration of the frame and the body and improve the ride comfort of the vehicle, the suspension system of the vehicle is generally equipped with a vibration damping device. The performance of the vibration damping device will directly affect the stability and comfort of the vehicle. life of other components. [0003] What is widely used now is the double-acting cylinder type shock absorber. The shock absorber cannot be adjusted according to the driving conditions, so that the shock absorber is relatively soft when it works on a flat road surface, which increases the power loss of the vehicle. On the road, it is relatively hard and cannot meet the comfort requirements. ...
