Abstract

The invention discloses an integrated type electromagnetic shock absorber. The integrated type electromagnetic shock absorber comprises a hydraulic buffer, an electromagnetic actuator, an upper threaded rod and a lower threaded rod, wherein the electromagnetic actuator comprises an actuator stator, an actuator promoter, an actuator promoter limiting plate, at least two actuator stator supporting rods and an actuator stator fixing seat; a stator central through hole is formed in the actuator stator; the actuator promoter penetrates through the stator central through hole; the upper end of the actuator stator is connected with the lower ends of the actuator stator supporting rods; and the actuator stator fixing seat is arranged at the upper ends of the actuator stator supporting rods, a plurality of grooves are formed in the inner surface of the actuator stator, coil windings are arranged in the grooves, permanent magnets are arranged on the outer surface of the actuator promoter, and the hydraulic buffer is arranged in a promoter central through hole. The electromagnetic actuator, the hydraulic buffer and a spring are integrated into a whole, and are designed to be slender, so thatthe reliability and the compactness of the electromagnetic actuator, the hydraulic buffer and the spring in an automobile suspension assembly are improved.

Description

technical field [0001] The invention belongs to the technical field of shock absorbers, in particular to an integrated electromagnetic shock absorber. Background technique [0002] The suspension system is one of the important components of the vehicle chassis system, and improving the performance of the suspension system is of great significance for improving the ride comfort and handling stability of the vehicle. Considering that the driving conditions of the vehicle are complex and changeable, the requirements for the suspension system are getting higher and higher, and the traditional passive suspension has been difficult to achieve satisfactory vehicle performance. The electromagnetic suspension actively adjusts and generates the required shock absorber force according to the motion state of the vehicle system and external input changes, and the response frequency can reach 1000Hz, which can make the vehicle system always have the best ride comfort and handling stabilit...
