Abstract

Disclosed is a magnetic shock absorber used on a motor vehicle, which combines the repellent force of magnets with the elastic force of damping springs and makes the two forces mutually complementary. The utility model comprises an installation ring, fixing plates and a damping spring connected between the fixing plates and is technically characterized in that an inner sleeve is arranged at the hollow part of the damping spring along the compression direction of the spring, and at least two magnet blocks are arranged inside the inner sleeve, with the same poles facing each other. Compared with the existing simple spring shock absorber or hydraulic shock absorber, the utility model is simpler in making process; particularly, the utility model, based on the existing spring shock absorber, is added with a cushioning structure with repelling magnetic poles, thus greatly improving the safety factor of the structure and furthermore reducing using cost of the vehicle and improving comfortableness during driving. The magnetic shock absorber has the advantages of low production cost, long service life, great self adaptability and bearing capacity, which is energy-saving and environment-friendly.

Description

The magnetic force vibration damper

Technical field

The utility model belongs to Motor Vehicle vibration damping equipment technical field, specifically a kind of magnetic force vibration damper that is applied to increase effectiveness in vibration suppression on the car bodies such as motorcycle, electric bicycle, mountain bike, Motor Vehicle and improves Safety performance.

Background technique

As everyone knows, the vibration damper that generally uses has two classes now: a class is the elastic damper that is made of the isometrical variable-pitch spring that an isometrical shock-absorbing spring or rigidity do not wait, this vibration damper is owing to be subjected to complete vehicle structure (length overall, diameter, volume etc.) and allow the restriction of applied stress, the rigidity of spring can only both be taken into account the moderate way of employing, its deficiency is: can not adapt to the variation of load weight, can adapt to the lighter vibration damper of load can not bear a heavy burden, the vibration damper that can bear a heavy burden effectiveness in vibration suppression when load is light is bad, which kind of spring all can reduce even lose because of sustained load elasticity in addition, and then reduces or the forfeiture damping property; Another kind of is hydraulic shock absorber, this vibration damper is the damping that utilizes flow of liquid to produce when aperture or the slit suffered impact endurance test shock of car body of decaying, in use, because wearing and tearing and scratch cause fluid to reveal, make it lose damping function, the fluid of revealing has also caused pollution to environment, and owing to the reason that manufactures and designs, the maintain and replace difficulty of this vibration damper, occur generally can only integral body scrapping after the leakage of oil, this just makes greatly reduce its working life, in order not influence the usability of car, can only in time change vibration damper, so just increase the user cost of car.

Summary of the invention

The purpose of this utility model provides a kind of homopolarity repulsive force that utilizes magnet and the shock-absorbing spring elastic force magnetic force vibration damper in conjunction with complementation.

The purpose of this utility model is achieved in that the shock-absorbing spring that it includes installing ring, fixed plate, connects between fixed plate, it is characterized in that: the shock-absorbing spring hollow part be provided with an inner sleeve along the length of spring compressed direction, in inner sleeve, be provided with at least two magnet pieces that homopolarity is relative.

In order to make the beautiful shape of this structure, prolong its working life, then the outside of shock-absorbing spring also is provided with an outer sleeve.

The utility model and existing elastic damper or the hydraulic shock absorber singly deposited relatively possess manufacturing process simply, has particularly increased the magnet homopolar-repulsion on the basis of existing elastic damper buffer structure, therefore improve the Safety performance of this structure widely, and then reduced the user cost of car, the comfort level that raising is driven.This is novel also have cost of production low, save advantages such as the energy, protection environment, long service life, adaptivity and bearing capacity are strong.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The utility model is described in further detail by example below in conjunction with accompanying drawing; but following example only is the utility model example wherein; the rights protection scope of not representing the utility model and being limited, rights protection scope of the present utility model is as the criterion with claims.

Embodiment

Describe concrete structure of the present utility model in detail according to Fig. 1.This device comprises installing ring 1, fixed plate 2, the shock-absorbing spring 3 that between fixed plate, connects, the shock-absorbing spring hollow part be provided with an inner sleeve 5 along the length of spring compressed direction, in inner sleeve, be provided with four magnet pieces 6 that homopolarity is relative.Also be provided with an outer sleeve 4 in the outside of shock-absorbing spring.

After being assembled into complete vibration damper according to the said structure manufacturing, be installed on the car body, mounting point, method are identical with mounting point, the method for existing vibration damper, the Therefore, omited.During driving, the impact endurance test shock that car body runs into by the elastic force of the shock-absorbing spring generation of compressing and the repulsion acting in conjunction that adjacent homopolar magnet produces, thereby has been eliminated the impact endurance test shock that car body runs into.

Claims

1. magnetic force vibration damper, it includes installing ring, fixed plate, the shock-absorbing spring that connects between fixed plate is characterized in that: the shock-absorbing spring hollow part be provided with an inner sleeve along the length of spring compressed direction, in inner sleeve, be provided with at least two magnet pieces that homopolarity is relative.

2. magnetic force vibration damper according to claim 1 is characterized in that: the outside of shock-absorbing spring also is provided with an outer sleeve.
