Example Embodiment

[0019] The present invention will be described in detail below with reference to the drawings and embodiments.

[0020] As attached Figure 1-4 As shown, the present invention provides a self-inductive reluctance electromagnetic damper. The damper includes a housing stator assembly and an internal mover assembly. The housing stator assembly is composed of an annular permanent magnet 3, an upper permanent magnet yoke 4, and a fastening bolt. 5. The upper support 6 and the lower permanent magnet yoke 8 are composed; the internal mover assembly is composed of the soft magnetic metal yoke 1, the coil 2, the lower support 9 and two linear bearings 7;

[0021] The upper yoke 4 of the permanent magnet and the lower yoke 8 of the permanent magnet are combined to form an annular cavity in which the annular permanent magnet 3 is installed. The annular permanent magnet 3 is installed in the annular cavity. The upper bracket 6 has a circular end cover. There is a guide shaft in the center of t...

Abstract

The invention discloses a self-inducing magnetic resistance type electromagnetic damper and belongs to the technical field of vibration noise control. The damper comprises a housing stator assembly and an internal active cell assembly, wherein the housing stator assembly and the internal active cell assembly are assembled together, the internal active cell assembly freely moves with respect to the housing stator assembly, a soft magnetic metal magnet yoke and a coil in the internal active cell assembly move in a magnetic field produced by the housing stator assembly, respectively produce eddy current and a Lorentz force hindering cutting magnetic induction line motion of the coil and meanwhile produce an electromagnetic force hindering cutting magnetic induction line motion of the soft magnetic metal magnet yoke, and the electromagnetic force is far greater than the Lorentz force. The damper can output lots of damping forces greater than a traditional electromagnetic damper, meanwhile has good anti-swing and anti-impact performance and has very high engineering applicability.

Description

technical field [0001] The invention belongs to the technical field of vibration and noise control, in particular to a self-inductance reluctance electromagnetic damper. Background technique [0002] The shock absorber is the main damping element in the vehicle suspension system, and it plays an important role in the ride comfort and safety of the vehicle. At present, most of the shock absorbers used on vehicles are double-acting cylinder type hydraulic shock absorbers. The biggest restrictive factor for hydraulic shock absorbers is that the maximum damping force produced is limited by the oil pressure and the increase in oil temperature affects the seal. performance impact. In order to improve the situation of the shock absorber, a series of new functional materials are used as the damping medium at home and abroad, such as magnetorheology and electrorheology. On the other hand, when the hydraulic shock absorber is designed as variable damping, the technical requirements ...
