Abstract

The invention aims to provide a hybrid energy feedback electromagnetic damper. The hybrid energy feedback electromagnetic damper comprises a piston rod, an upper end cover, a cylinder body, a coil and a piston head, damping channels are designed in the piston rod and the piston head, a stepped magnetorheological fluid damping gap is formed, the effective length of the damping channels is increased, and output of damping force is increased. Conductor rings are installed on the inner sides of radial permanent magnets of the Haerbert permanent magnet array, the permanent magnets are prevented from directly adsorbing magnetic particles in magnetorheological fluid, on one hand, the maximum value of damping force is increased, on the other hand, the adjusting range of the damping force is greatly increased, and the damping force is adjusted more flexibly and intelligently. The hybrid energy feedback electromagnetic damper overcomes the defects that an existing damping device is small in output damping force maximum value, large in size and complex in structure, and has the advantages of being maximum in output damping force maximum value, large in damping force adjusting range, small in size and simple in structure.

Description

technical field [0001] The invention relates to an automobile suspension damper device, in particular to a hybrid energy-feeding electromagnetic damper. Background technique [0002] When the car is running daily, only about 14%-26% of the fuel energy is used to drive the car, and most of the rest of the energy is converted into heat energy and dissipated. The energy-feeding electromagnetic damper can cut the magnetic field line through the coil. Convert part of the heat energy loss generated by the vibration between the wheel and the body into electrical energy, and output voltage to supply power to the car suspension system or other electronic components to improve energy utilization. [0003] In order to increase the damping force of the existing energy-feeding electromagnetic damper, it is usually connected with a hydraulic damper or a magnetorheological damper, but the connection method is usually only a mechanical connection, resulting in a large volume and a complex s...
