Detailed description of the invention
With reference to the accompanying drawings, the embodiment of brake equipment of the present invention is described.In the process, the thickness of the lines shown in accompanying drawing or the size etc. of structural element, in order to the definition that illustrates and convenient and may show turgidly.In addition, the term that term described later defines as the function considered in the present invention, may be different because of the intention of user, operator or convention.Therefore, the definition for this term should be determined based on the content of this specification.
Fig. 1 is the skeleton diagram of the brake equipment representing one embodiment of the present of invention.Fig. 2 represents in the brake equipment of one embodiment of the present of invention, the skeleton diagram of the state of brake pedal pressurization.Fig. 3 represents in the brake equipment of one embodiment of the present of invention, removes the skeleton diagram of the state to brake pedal pressurization.Fig. 4 represents in the brake equipment of one embodiment of the present of invention, embodies the skeleton diagram of the state of attitude of bodywork controlling functions.
As shown in Figures 1 to 4, with regard to the brake equipment 1 of one embodiment of the invention, front-wheel carries out ACTIVE CONTROL by means of actr (Actuator), and whether trailing wheel controls pedal pressurization according to chaufeur.
In the brake equipment 1 of one embodiment of the invention, be equipped with control cylinder portion 10, supervisor portion 20 and auxiliary tube portion 30, implement rear service brake by means of pedal.
Store brake noise in control cylinder portion 10, whether according to pedal pressurization, brake noise is discharged by discharge opening.
Supervisor portion 20 is the car side brake 40 of the brake noise guiding trailing wheel of discharging from control cylinder portion 10.One end in supervisor portion 20 is connected to the discharge opening in control cylinder portion 10, and the other end is connected to car side brake 40.
End, auxiliary tube portion 30 1 is connected to supervisor portion 20, and the other end is connected to reservoir 50.This auxiliary tube portion 30 also can be from branch of supervisor portion 20 out, in reservoir 50, store brake noise temporarily.
Reservoir 50 is connected with supplementary pipe 51.This supplementary pipe 51 1 end is connected to reservoir 50, and the other end is connected to control cylinder portion 10.
Reservoir 50 is positioned at than control cylinder portion 10 higher height.Therefore, by means of gravity, the brake noise stored in reservoir 50 is supplied to control cylinder portion 10.
Boiler check valve 31 is equipped with in auxiliary tube portion 30.Boiler check valve 31 cuts off brake noise from supervisor portion 20 to the movement of reservoir 50, guides brake noise to move from reservoir 50 to supervisor portion 20.
Hydraulic pressure regulator 21 is equipped with in supervisor portion 20.Hydraulic pressure regulator 21, under the microcomputerized control controlled for attitude of bodywork, is supplied to car side brake 40 by pump to the oil stored in reservoir 50.
Such as, hydraulic pressure regulator 21 is configured in the supervisor portion 20 between boiler check valve 31 and car side brake 40.By means of the suction of this hydraulic pressure regulator 21, the brake noise stored in reservoir 50 is supplied to car side brake 40.
Below the effect of brake equipment of the one embodiment of the invention with as above structure is described.
One end in supervisor portion 20 is connected to the discharge opening in control cylinder portion 10, and the other end in supervisor portion 20 is connected to the car side brake 40 of trailing wheel.
One end in auxiliary tube portion 30 is connected to supervisor portion 20, and the other end in auxiliary tube portion 30 is connected to reservoir 50.
Be equipped with hydraulic pressure regulator 21 in supervisor portion 20, be equipped with boiler check valve 31 in auxiliary tube portion 30.
In the above-described state, if chaufeur is to brake pedal pressurization (with reference to Fig. 2), so, brake noise is discharged by the discharge opening in control cylinder portion 10.The brake noise of discharging is supplied to car side brake 40 by supervisor portion 20.
Now, boiler check valve 31 keeps the state of cutting out auxiliary tube portion 30.Therefore, by means of boiler check valve 31, the hydraulic pressure transfer to reservoir 50 side is cut off.And, by reducing the discharge opening size in control cylinder portion 10, dumping force can be obtained by means of orifice effect.
On the other hand, if chaufeur removes the pressurization (with reference to Fig. 3) to pedal, so, the plunger in control cylinder portion 10 returns, and brake noise returns to control cylinder portion 10.
Now, if the return velocity of brake noise is slower than the return velocity of plunger, so, auxiliary tube portion 30 opened by boiler check valve 30.Due to opening of this auxiliary tube portion 30, the brake noise of reservoir 50 is supplied to supervisor portion 20, and brake noise is supplemented.
In addition, in attitude of bodywork control process (with reference to Fig. 4), hydraulic pressure regulator 21 drives, and boiler check valve 31 stays open.
Therefore, the brake noise stored in reservoir 50 arrives rapidly car side brake 40.
The present invention is the explanation carried out with reference to embodiment shown in the drawings, but this is example, and person of an ordinary skill in the technical field it is to be understood that other embodiments that can realize various deformation and equalization thus.
