Description

Vehicle brake synergy energy disperser

The utility model relates to a kind of car brake, particularly relates to a kind of braking automobile synergy energy disperser.

Car brake is used in reaching that existing market is sold, glancing impact in case of emergency, the afterbody of car all will upwards lift again and fall, this is that one of back formation is the moment of torsion in the center of circle with the axletree on axletree and the vehicle frame because the rotary inertia of wheel and engine-drive spare acts on when brake, the tailstock makes progress work so that headstock is downward, showing of this un-reasonable phenomenon, can't solve there to be many decades.Particularly the ground-surface friction force is very little and make braking ability very low when ice and snow road is exercised, and causes a lot of Peril Incidents.Can make full use of the inertia of driving engine and Transmission with the utility model, can improve the usefulness of stopping greatly, being equipped with the anti-dead system braking effect that digs of ABS now again can be better.

The purpose of this utility model at the problem of above existence, provides a kind of way of solution, exactly in drg back-plate and wheel the place ahead when setting overcomes in emergency brake, because the moment of torsion that the rotor inertia of wheel and engine-drive parts produces.The effect that utilizes moment of torsion wheel shaft can change the direction of power makes its circumference rotary inertia development of evil in febrile disease become tangential straight line inertia, just change into along realize the braking effect of synergy of the tangential back pull of energy disperser, this power is big and fast, the system that is provided with is that the pulling force that produces when the brake is cushioned liquid in the device and absorbs buffering and slow down along the principle of work of energy disperser, when decontroling brake, in the energy disperser pull back spring is arranged, pull bar is regained in order to elongating next time, so continuous elongation return, strengthened braking ability again greatly thereby solved the phenomenon that the automobile tail upwarps, steady when making brake, more comfortable, safer.

The purpose of this utility model is achieved in that it comprises a drg, is characterized in that: be provided with a buffer of brake on the drg of setting up, the one end is connected with brake support plate, and the other end is built up in behind the front-wheel on the vehicle frame; One is the metal brake wheel of running surface with the internal circular surfaces, be fixed on the tire, together rotate with vehicle, be contained on the back-plate on the axle, have two rest pins supporting the lower end of two arc brake shoe brake cheek, on the brake shoe brake cheek periphery, being equipped with again generally is nonmetallic friction lining, the hydraulic braking wheel cylinder also is housed on the back-plate, is connected with hydraulic brake master on being contained in vehicle frame with oil pipe, the piston in the master cylinder can be handled by brake treadle mechanism by chaufeur.

Described energy disperser upper end is hooked on vehicle frame back plate, the eye bolt, and the lower end is hooked on the back-plate rest pin.

The utility model has the advantages that: it is simple in structure, and it is reasonable that the position is set, and is creative, convenient and practical, the phenomenon that automobile tail upwarps when having solved vehicle and braking recent decades, and usefulness improves when making brake, steady, quiet, comfortable, safety.

The utility model is described in further detail below in conjunction with drawings and Examples.

Description of drawings is as follows:

Fig. 1 is a cutaway view of the present utility model.

The accompanying drawing piece number is represented:

1, brake pedal 2, push rod 3, master cylinder piston

4, master brake cylinder 5, oil pipe 6, brake wheel cylinder

7, wheelcylinder piston 8, brake wheel 9, friction lining

10, brake shoe brake cheek 11, back-plate 12, bogie wheel

13, the energy disperser of brake check spring 14, rest pin 15, band return spring

16, eye bolt 17, nut 18, back plate

19, vehicle frame

Referring to Fig. 1, the integral structure of the utility model product and composition: it comprises a drg, establishes 1 buffer of brake 15 on the drg of setting up, and the one end is connected with brake support plate, and the other end is built up on the wheel front vehicle frame; One is the metal brake wheel 8 of driving surface with the inside face, is fixed on the tire, together rotates with vehicle, on fixed back-plate 11, two bogie wheels 12 are arranged, the lower end of supporting two arc brake shoe brake cheek 10, being equipped with again on brake shoe brake cheek 10 outer round surface generally is nonmetallic friction lining 9.Hydraulic braking wheel cylinder 4 also is housed on the back-plate 11 is connected, 4 piston 3 in the master cylinder can be handled by pedal gear 1 by chaufeur.

Glancing impact, chaufeur is stepped on slipper 1, by push rod 2 and master cylinder piston 3, make the fluid in the master cylinder under certain pressure, flow into wheel cylinder 6, and pass through two wheelcylinder pistons, 7 promotions, two brake shoe brake cheek 10 and rotate around rest pin 12, but the both sides, upper end separately, and be pressed on the inner headed face of brake wheel with its friction lining 9, brake shoe brake cheek is the friction moment Mu of brake wheel effect to rotating just, so because the effect of power be mutual brake wheel simultaneously also to oppositely directed moment of brake shoe brake cheek plate, act on the shoe sole, an opposing torque, become one to the pulling force of car body by the energy disperser development of evil in febrile disease, car is slowed down, thereby improve the usefulness of brake to the back lower place.After brake wheel passed to vehicle with elastic force apart from Mu simultaneously, the road surface energy disperser just was braking force to directed force F b backward of wheel effect.Braking force Fb passes to vehicle frame and own by wheel through vehicle bridge and suspension, forces whole automobile to produce certain deceleration/decel.

When emergency brake, often automobile tail has the phenomenon that upwarps to be produced as this product difficult problem of solution, adorns a rest pin 14 in back-plate 11 bottoms, energy disperser 15 1 end hooks is arranged in the above, the other end then is hooked on the eye bolt 16, by the hole of the back plate 18 on the fixing vehicle frame 19.There is nut 17 fixing, also can adjusts simultaneously energy disperser 15.Its energy disperser can the time slow down the generation of the phenomenon that automobile tail upwarps in brake.Produce a pulling force backward simultaneously, behind the loosen the brake, make brake shoe brake cheek 10 under the effect of pull back spring 13, friction lining 9 resets.Separate with brake wheel.
