Description

A kind of braking device

Technical field:

The present invention relates to the improvement of braking device structure.

Background technique:

Present vehicle braked system because of its braking force source power be medium potential energy by means of medium as braking force source power, cause the brake system structure complexity of the vehicles such as visitor, goods and car of current all kinds, weight, grade, can not unify; Stopping distance because of the emergency braking in the braking process that travels of its vehicle requires short again, and turning radius causes vehicle that serious security and stability problem takes place for a short time, especially in the process of moving, when braking causes the load weight transfer, the adhesion on wheel and road surface also will change thereupon, wanting to obtain desirable braking just must have different braking force,, adopts fixed braking force distribution than valve system when common convention braking force distribution; But, decide not accomplish to adapt to various braking than valve system and distribute desired condition.

For this fixed the best braking than valve system braking force distribution, only under the situation of a certain specific wheel and road adherence, can reach desirable best braking.

In addition, existing brake device structure complexity, in order to adapt to the vehicle of different sizes, the braking device of use is also inequality, can't reach unitized, and is serious to the influence on development of automobile.

Summary of the invention:

The present invention is exactly at the problems referred to above, provides a kind of need not by medium potential energy can adapt to a kind of braking device of various vehicles as braking force source power.

For reaching above-mentioned purpose of the present invention, the present invention adopts following technological scheme, the present invention includes the fixed cover with chassis and the housing with brake disc, is disposed with driven fluted disc, energy storage cover and brake component on its structure outline fixed cover from left to right; Motor with driving gear is set on the chassis, and driving gear is meshed with driven fluted disc; Described energy stores cover and comprises middle left push pedal and right push pedal with butterfly spring; The left friction plate and the right friction plate that have Returnning spring in the middle of described brake component comprises; Energy stores cover and radially is fixed on the fixed cover; Right push pedal is fixed on the fixed cover; Thrust ball between left side push pedal and the driven fluted disc is arranged in the skewed slot of left push pedal, and contacts with driven fluted disc; Deciding in the groove that ball is arranged at right push pedal between right push pedal and the left friction plate, the skewback on the left friction plate contacts with deciding ball; The brake disc of described housing is arranged between left friction plate and the right friction plate.

Beneficial effect of the present invention:

1, because structural feature of the present invention, when stepping on brake, the driven fluted disc of driven by motor rotates, thrust ball is rolled by down fold top, skewed slot bottom, thereby promote energy and store cover, energy stores cover and promotes left friction plate, and when left friction plate contacted with brake disc, brake disc drove brake component and rotates; The top ball that energy stores the cover right side moves to the skewback eminence, makes brake component clamp brake disc; And this braking force comes from the rotatory force of wheel fully; So the present invention need not to use other media potential energy as braking force source power.

2, the present invention is directly with the kinetic energy of the car that obtains on the brake disc and the adhesion between wheel and the road surface braking force source power as car, brake disc is given in this braking force source power effect of recycling, so, the present invention can shift along with the weight that takes place in the running process, the variation of adhesion between wheel and the ground and changing; And the belleville spring that energy stores in the cover changes the effect that also can play buffering to these, and these variations are saved as elastic potential energy, feeds back to brake component again; Therefore, the present invention can adapt to various vehicles, is not subjected to car weight, the restriction of vehicle, even can be applied in the braking of aviation and rail train.

3, the present invention is simple in structure, adapts to widely, is easy to unitize, seriation, specialized production, is conducive to popularize.
