Abstract

The utility model provides a permanent magnet electromagnetic adjustable shock absorber, wherein, a spring used for shock absorption is arranged between a vehicle bearing shaft and a fulcrum shaft of a vehicle rolling shaft; in a spring, a permanent magnet core is arranged on the lower end of the bearing shaft; a coil and a coil armature are arranged on the upper end of the fulcrum shaft of the vehicle rolling shaft; when a circuit is conducted, the permanent magnet core and the coil armature are opposite to each other homopolarly (S) and the magnetic forces repulse each other. Under general conditions, the spring of the permanent magnet electromagnetic adjustable shock absorber plays a part in shock absorption; under the condition of bad roadways or rapid driving speed, the bounce force of the fulcrum shaft on the vehicle rolling shaft is increased and the spring compression is large, the permanent magnet core on the lower end of the bearing shaft and the coil armature on the upper end of the fulcrum shaft are closer to each other, and then the magnetic suspension force which repulses each other with the same nature is generated and matched with the elasticity of the spring so as to absorb shock of vehicles and achieve the aim of protecting the safety of the vehicles and vehicle-carried articles and the driving quality better.

Description

The permanent-magnett electromagnetic adjustable damper

Technical field

The utility model relates to a kind of vehicle shock absorber, specifically is a kind of permanent-magnett electromagnetic adjustable damper.

Background technique

The polytype vibration damper is arranged at present, and if any hydraulic type, spring, electromagnetic type, the Sealing of hydraulic type is aging easily, easily causes leakage of oil and environmental pollution problem; Spring is to utilize the restorable ability of object, and this mode is easy to generate fatigue, fracture in frequent deformation repeatedly; Electromagnetic type is to use the resulting magnetic suspension of two same pole generation repulsive forces to reach vibration isolation.Because vehicle-mounted load and road quality is different, same electromagnetism damping can't be protected the safety of vehicle and vehicle-mounted thing and the quality of travelling better.

Summary of the invention

The purpose of this utility model is: a kind of electromagnetic valve type is provided, can adjusts the permanent-magnett electromagnetic adjustable damper of magnetic force size, cooperate spring shock absorption, reach the safety of protecting vehicle and vehicle-mounted thing better and the quality of travelling.

The utility model by technological scheme be: between the fulcrum on vehicle load-bearing axle and the vehicles roll axle, arrange spring shock absorption, at spring inside: load-bearing axle lower end makes the permanent magnetism iron core, the upper end of fulcrum makes coil on the vehicles roll axle, coil armature, when connecting circuit, the permanent magnetism iron core is that homopolarity (S) is relative with coil armature, and magnetic force repels mutually.

The utility model according to the technique scheme making; ordinary circumstance is that spring plays cushioning effect; poor at road; or the speed of a motor vehicle is when fast, and the fulcrum spring on the vehicles roll axle increases, and length of spring compressed is big; the coil armature distance of the permanent magnetism iron core of load-bearing axle lower end and fulcrum upper end contracts near; the magnetic suspension force that produces same sex repulsion cooperates the elastic force of spring, makes vehicle reduce vibrations, reaches and can protect the safety of vehicle and vehicle-mounted thing and the purpose of ride quality better.

Description of drawings

Accompanying drawing 1 is a front elevational schematic of the present utility model, and accompanying drawing 2 is cross-sectional schematic of the present utility model.Among the figure: 1, load-bearing axle, 2, bearing and spring bracket device, 3, spring, 4, bearing and spring seat device, 5, the fulcrum on the vehicles roll axle, 6, a bracing strut, 7, the permanent magnetism iron core, 8, coil armature, 9, coil, 10, circuit.

Specific embodiments

The utility model specific embodiments: load-bearing axle (1) is by bearing and spring bracket device (2) fixed position, and there is permanent magnetism iron core (7) load-bearing axle lower end.Fulcrum on the vehicles roll axle (5) is by bearing and spring seat device (4) fixed position on a bracing strut (6) and the support.Spring (3) pushes up top spring bracket device from the spring seat device.Fulcrum upper end on the vehicles roll axle makes coil (9) and coil armature (8), and it is that homopolarity (S) is relative that coil armature is settled with the permanent magnetism iron core.The circuit (10) that coil links extends in outside the device.

Claims (3)

1, a kind of permanent-magnett electromagnetic adjustable damper, it is characterized in that: vehicle load-bearing axle is by bearing and spring bracket device fixed position, there is the permanent magnetism iron core load-bearing axle lower end, and the fulcrum upper end on the vehicles roll axle makes coil and coil armature, and it is that homopolarity is relative that coil armature is settled with the permanent magnetism iron core.

2, permanent-magnett electromagnetic adjustable damper according to claim 1 is characterized in that: the fulcrum on the vehicles roll axle is by bearing on support and the support and spring seat device fixed position.

3, permanent-magnett electromagnetic adjustable damper according to claim 1 is characterized in that: the spring bracket device of spring above the spring seat device pushes up.
