JPH09267727A - Fluid seal type brake for automobile - Google Patents

Abstract

PROBLEM TO BE SOLVED: To realize a strong brake effect by transmitting kinetic energy to a fluid, sealing a circulating path of the fluid by a control cam, and stopping a motion of a piston. SOLUTION: Two pistons 2 are pushed/pulled by a rotary shaft 1 transmitted from a rotary unit 8 of a tire or the like, and oil 3 is fluidized in an oil chamber 4 by mutually opposed operation of the two pistons 2. Here, fluidization of the oil 3 is stopped by a control cam 5, so as to stop the piston 2, and the rotary shaft 1 associated with this piston 2 is stopped and controlled so as to apply a brake. In this way, since auxiliary control of a computer by a pulse motor can be performed, and an effect of antilock brake or the like can be also expected.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle brake.

[0002]

2. Description of the Related Art Disc brakes, drum brakes, etc.

[0003]

Most conventional brakes for automobiles convert kinetic energy into heat energy, and have a problem such as a fade phenomenon.

[0004]

SUMMARY OF THE INVENTION In order to eliminate the drawbacks of the present invention, the kinetic energy is transmitted to the fluid, and the passage of the fluid is closed by a control cam such as 5, and the movement of the piston is stopped. Is realized.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION Since the present invention has the above-mentioned structure, a stronger braking effect can be expected as compared with the case of directly pressing a disc or a drum.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention operates five control cams by interlocking with the brakes of an automobile. The rotating body 8 can be interlocked with the tire, or can be placed between the clutch and the driving wheel to intensively control the brake because heat radiation is not necessary. 5
The control cam of the can also be used as an anti-lock brake by supplementing the control of the computer by the pulse motor and servo motor.

[0007]

Since the present invention has the above-described structure, it does not cause wear on the brake butt or the like and therefore has no effect on the environment.
It can also solve problems such as the brake not working due to the fade phenomenon. Also, since there is no need to radiate heat,
The brake can be controlled in one place between the drive wheels, which helps reduce costs.

Claims (1)

[Claims] 1. A rotary shaft (1) transmitted from a rotating body (8) has two pistons (2) for pushing and pulling, the movements of which are opposite to each other, and the pistons (2) move to thereby cause an oil chamber. The oil (3) moves in (4), resulting in the state shown in FIGS. The control cam (5) is arranged as shown in FIG. 4, and the piston (2) is stopped by stopping the flow of the oil (3), and the rotary shaft (1) interlocking with it is stopped to serve as a brake.
