Electromagnetic Spring Shock Absorber

Abstract

The invention relates to an adjustable electromagnetic spring vibration absorber with functions of both an elastic element and a damping element. The electromagnetic spring vibration absorber comprises a first fixed electromagnet, a second fixed electromagnet, a first movable electromagnet, a second movable electromagnet, a speed sensor and a controller, wherein the first fixed electromagnet and the second fixed electromagnet are arranged at the upper end and the lower end of a sleeve respectively, the first movable electromagnet and the second movable electromagnet are arranged on one side of a piston relative to the upper end and the lower end of the sleeve respectively; and the speed sensor is arranged on the piston and is connected with the controller. According to the invention, through reasonable arrangement of a plurality of electromagnets, an electromagnetic spring generates a vibration absorption damping, so that the electromagnetic spring vibration absorber replaces two suspension components, namely a coil spring and a vibration absorber, solves the problems that the suspension stiffness and the suspension height in the conventional vehicle suspension structure are not adjustable and can not meet the requirements of riding comfort and trafficability under complex road conditions, and eliminates the potential hazard of hydraulic oil leakage of the vibration absorber.

Description

technical field [0001] The invention relates to a suspension mechanism of a vehicle, in particular to an adjustable electromagnetic spring shock absorber which has both the functions of an elastic element and a damping element. Background technique [0002] Suspension is the general term for all force-transmitting connection devices between the frame of the car and the axle or wheels. The impact force of the car body and attenuate the vibration caused by it, so as to ensure that the car can run smoothly. A typical suspension structure is composed of elastic elements, guide mechanisms, and damping elements. The elastic elements usually used in cars are coil springs, which play a role in buffering vibrations. The commonly used damping elements are shock absorbers, which serve the purpose of damping vibrations. [0003] figure 1 Schematically shows a common vehicle suspension main structure mainly composed of a coil spring and a shock absorber, which includes: a shock absorbe...

Problems solved by technology

[0006] The purpose of the present invention is to provide an adjustable electromagnetic spring shock absorber which has both the functions of an elastic element and a damping element, so as to overcome the non-adjustable suspension stiffness and non-adjustable suspension height in the existing vehicle suspension structure. It cannot meet the requirements of ride comfort and vehicle passability in complex road conditions, and eliminates the hidden danger of shock absorber hydraulic oil leakage
