Abstract

A damper for vehicle includes one fixed sleeve inside which there are at least two permanent magnets, among which one is fixed at one end of the sleeve and the other is a sliding one, and one slide block connected to the sliding magnet at one end and to the damping carrier of vehicle via one connecting part. The permanent magnets inside the sleeve are arranged in the polarity mode of repelling each other. The damper of the present invention as a new type damper is simple in structure and obvious in damping effect, and no defects of oil and air leakage and fatigue breakdown.

Description

The shock absorber that is used for vehicle

The invention of this reality and a kind of shock absorber especially relate to the shock absorber that is used for vehicle such as power actuated vehicles such as automobile, motor bike.

Power actuated vehicle produces vibration in the process of moving, be to quicken the decay of vibration, and that improves vehicle ' calms down the polygamy stability, and power actuated vehicles such as automobile, motor bike generally all are equipped with shock absorber in its draft hitch.At present, several, for example shown in Figure 3 spring damper of the general shock absorber that adopts of power actuated vehicle as shown in Fig. 3-8, it mainly comprises damper cylinder 110, cushion rubber 111, spring 112, spring perch 113, oil-containing lining 114, sealing shroud 115, front fork tube 116; Fig. 4 shows a kind of air damp type and shakes and subtract device; Fig. 5 shows a kind of spring hydraulic type shock absorber; Fig. 6 shows a kind of bellows type air spring shock absorber; Fig. 7 shows a kind of diaphragm type air spring shock absorber; Fig. 8 shows a kind of hydro-pneumatic spring type shock absorber.There is spring mechanical fatigue fracture problem respectively in above-mentioned these shock absorbers, and damping medium is as the leakage problem or the rubbery intensity problem etc. of air, oil.And this area generally is rugosity or a thickness by reinforcement material at the problems referred to above, or is solved by improving leak tightness, but these means fundamentally do not solve the leakage problem of oil, gas, and fractureing of spring still exists.

Purpose of the present invention overcomes the deficiencies in the prior art exactly, and a kind of shock absorber that uses under the various working conditions that is useful in is provided, and this shock absorber reaches the vibration damping purpose by the mutual action of magnetic pole, does not have the damping medium leakage problem.

The objective of the invention is to realize by following technical proposals, shock absorber of the present invention, it is characterized in that it comprises a fixed muffle, in fixed muffle, be placed with at least two permanent magnets, wherein a permanent magnet is the end of being fixed in fixed muffle, and another piece permanent magnet is to be placed on slidably in the stationary magazine creel, also be provided with a slide block in the fixed muffle, one end of this slide block links to each other with permanent magnet slidably, and the other end links to each other with the vibration damping carrier of power actuated vehicle by a connection piece, and the permanent magnet in the fixed muffle is to be provided with to the mode of repelling each other with the utmost point.

Ride-control of the present invention is to reach the vibration damping purpose by the mutual repulsion between the permanent magnet in the fixed muffle, the magnetic intensity of permanent magnet can be selected according to the needs of car body self, thereby makes mutual expelling force between the permanent magnet can reach the needs of vibration damping.

In order to strengthen effectiveness in vibration suppression, permanent magnet is multistage combined in the said fixing sleeve, promptly slidably places at least one permanent magnet among the permanent magnet at fixing permanent magnet mutually with slide block, and the permanent magnet of being placed all is to be provided with to the phase mode with the utmost point.

In order to reduce the friction between slip permanent magnet and the fixed muffle, a lining can be set between them.

Advantage of the present invention is, simple in structure, good damping result has overcome the oil of conventional truck shock absorber, the shortcoming of gas leakage, and the defective of the fatigue fracture of member such as spring, for the vibration damping of vehicle provides a kind of improved new way.

Further describe structure of the present invention below in conjunction with accompanying drawing; Wherein

Fig. 1 is the generalized section of ride-control of the present invention;

Fig. 2 is the scheme drawing of another embodiment of ride-control of the present invention;

Fig. 3 is traditional spring damper;

Fig. 4 is traditional air damp type shock absorber;

Fig. 5 is traditional spring hydraulic type shock absorber;

Fig. 6 is traditional bellows type air spring shock absorber;

Fig. 7 is the diaphragm type air spring shock absorber:

Fig. 8 is the hydro-pneumatic spring type shock absorber.

Now referring to Fig. 1, the shock absorber that is used for vehicle of the present invention comprises a fixed muffle 1, in fixed muffle 1, be placed with at least two

permanent magnets

2 and 3, wherein a permanent magnet 2 is ends of being fixed in fixed muffle 1, and another permanent magnet 3 is to be placed on slidably in the fixed muffle 1 along F-F ' direction, also be provided with a slide block 4 in the described fixed muffle 1, one end of this slide block 4 links to each other with permanent magnet 3 slidably, and the other end is by a connection piece 5 and link to each other with the vibration damping carrier (not shown) of power actuated vehicle;

Permanent magnet

3 and 4 is to place to the mode of repelling each other with the utmost point.

Fig. 2 shows another embodiment of shock absorber of the present invention, it is on the basis of shock absorber shown in Figure 1, in fixed muffle 1, set up a slidably permanent magnet 6, with the mutual expelling force between the enhancing magnet, in its fixed muffle 1

permanent magnet

3 and 6 and fixed muffle 1 between can be provided with a lining (not shown), to reduce abrasion to fixed muffle 1.

Claims
