Abstract

The invention discloses a permanent magnet and electromagnet cross-linked suspension type reclaiming energy type active suspension actuator. The actuator comprises a piston rod, an end cover, a rod end buffer spring, a cylinder tube, an induction coil, a cross-linked piston assembly, an electromagnet control electrode, a tail end buffer spring, a retainer, a tail cover, a reclaiming energy circuitand an electrode brush, wherein the upper end of the cylinder tube is connected with the end cover, the other end of the cylinder tube is connected with the tail cover, the piston rod, the inductioncoil, the electromagnet control electrode and the retainer are located in the cylinder tube; the piston rod penetrates through the end cover and the rod end buffer spring in sequence, the lower end ofthe piston rod is connected with the cross-linked piston assembly, and the other end of the cross-linked piston assembly is connected with the tail end buffer spring; the reclaiming energy circuit iselectrically connected with the induction coil, the electromagnet control electrode is connected with the electrode brush, and the cross-linked piston assembly can move vertically along with the piston rod. The provided permanent magnet and electromagnet cross-linked suspension type reclaiming energy type active suspension actuator has the advantages that the structure is simple, and the arrangement is convenient.

Description

technical field [0001] The invention belongs to the technical field of automobile system and structural design and magnetic suspension, and in particular relates to a permanent magnet and electromagnetic cross-linked suspension type energy-feeding active suspension actuator. Background technique [0002] Modern cars are developing in the direction of safety, comfort, energy saving, environmental protection, and intelligence. People's pursuit of car comfort and overall quality is increasing day by day. The application of automotive active suspension system can significantly improve vehicle ride comfort, handling stability and NVH performance, thereby greatly improving the driving experience, and has become one of the hot spots in automotive technology and product development. However, at this stage, the working principle of the core mechanism of this type of system basically follows the traditional hydraulic shock absorber (damping) and linear motor (stiffness / force) control ...

AI Technical Summary

Problems solved by technology

The actuator of this technology uses a rotating electromagnetic energy feeder and a hydraulic damping structure at the same time. The structure is relatively complicated, the manufacturing cost is high, and only a small part of the vibration energy is recovered. The way of the hydraulic damping system is not pure in terms of controllability and response speed. Electromagnetic system is good
