Abstract

The invention provides a rotary eddy current damper with adjustable damping. The rotary eddy current damper comprises a conductor cylinder, a rotating shaft, an outer cylinder, a screw rod, a screw rod nut and a permanent magnet set, wherein the screw rod nut sleeves the screw rod; the screw rod and the screw rod nut are arranged in the outer cylinder and the screw rod, the screw rod nut and the outer cylinder are coaxially arranged; the screw rod nut is rotationally arranged on the inner wall of the outer cylinder through a second bearing; the rotating shaft is of a hollow structure; the rotating shaft sleeves the periphery of the screw rod and is coaxial with the screw rod; one end of the rotating shaft is fixedly connected with the screw rod nut; the permanent magnet set comprises a plurality of permanent magnets; the plurality of permanent magnets are uniformly and annularly arranged on the outer wall of the rotating shaft; the conductor cylinder is arranged on the inner wall of the outer cylinder; and the conductor cylinder and the permanent magnets are oppositely arranged. The position of the conductor cylinder in the axial direction of the outer cylinder is adjusted throughan adjusting nut, so that the mapping area of the permanent magnets on the conductor cylinder is adjusted, and the range adjustment of eddy current damping force is realized.

Description

technical field [0001] The invention relates to the technical field of shock absorbers, in particular to a rotary eddy current shock absorber with adjustable damping. Background technique [0002] The vibration reduction and isolation performance of the vehicle suspension system directly affects the running quality of the vehicle such as stability and comfort. For a long time, the vehicle suspension system has gradually formed a passive spring-damper structure that is still in use today, and its damping performance is gradually difficult to meet the requirements under the development trend of pursuing intelligence and comfort; in addition, the damping unit often uses hydraulic shock absorbers, etc. Viscous dampers have disadvantages such as difficulty in maintaining stable performance for a long time, oil leakage, high temperature influence, and high requirements for intelligent technology. Therefore, the suspension system is in urgent need of a breakthrough. [0003] The ...
