DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a brake apparatus for an automobile which can efficiently brake on a frozen road surface even while traveling.

[0002]

2. Description of the Related Art Conventionally, as means for braking on a frozen road surface of an automobile, a spike tire in which sand is sown on a frozen road surface, a pin is embedded in a tire, and a studless tire in which the rubber material of the tire is significantly improved. And so on. These braking means are very effective on snowy roads. Also, if the chain is wound around tires, it becomes a very effective braking means on snowy roads and icy roads.

[0003] However, in the braking means in which sand is sown on a frozen road surface to suppress slippage, the braking force is lost when the sand is lost, which is extremely dangerous. . In addition, if the spike tire is attached to the car, although braking force can be obtained, driving on roads other than frozen roads will generate dust and cause dust pollution and drive from frozen roads to general roads other than frozen roads In this case, the tires must be replaced with normal tires before traveling on a general road, which is extremely complicated.

[0004] Next, braking means for winding a chain around a tire is difficult to adapt to the road surface by this means, and vibration occurs due to unevenness of the chain itself during running.
The vibrations are transmitted to the vehicle body, causing discomfort to the driver and generating noise.The tires must be removed and removed even in the complexity of removing and mounting in cold winds. Even so, it cannot be stopped reliably.

Therefore, an improved chain called a rubber chain has been manufactured and used. However, the maneuverability and riding comfort on snowy roads and frozen roads have been improved, but the need for troublesome attachment / detachment and removal / removal in cold wind is required. This is the same, and even if the rubber chain is mounted, the vehicle cannot be stopped efficiently on a frozen road even if a brake is applied.

Further, the studless tire has a drawback that the studless tire exerts a braking effect extremely effectively on snowy roads, but has a very poor braking effect on frozen roads.

[0007]

SUMMARY OF THE INVENTION The present invention has a sufficient braking force even when traveling on a frozen road, is extremely easy to operate, does not break down, and has an additional effect on the vehicle body during braking. It is an object of the present invention to provide a brake apparatus for a vehicle which can be easily operated without giving any vibration.

b, operating members 1 and 1a including a fixing member, a hydraulic cylinder, an adjusting spring, and the like, and braking pads 2 and 2a.

The automotive brake system A is connected to the same brake pedal 7 as the brake pedal 7 for operating the brake system for braking the front wheels and the rear wheels. Of course,
The automotive brake device A may be installed on the vehicle body as a completely different brake device.

One end of the brake pedal 7 is attached to the master cylinder 6 so that the movement of the brake pedal 7 is transmitted to the master cylinder 6. An oil supply pipe 4 is attached to the master cylinder 6, and the oil supply pipe 4 supplies a first oil supply pipe 4 a for supplying oil to a hydraulic cylinder 14 of the operating section 1 and a second oil supply for braking the rear wheel 10.
It branches to the oil supply pipe 4b. Reference numeral 5 denotes a hydraulic pressure adjustment level for adjusting the oil pressure in the oil supply pipe 4a.

The master cylinder 6 and the hydraulic cylinder 14 of the operating unit 1 are connected by an oil supply pipe 4 and a first oil supply pipe 4, and the movement of the brake pedal 7 is transmitted to the hydraulic cylinder 14 of the operating unit 1, and the movable member The brake pad 2 is pressed against a frozen road surface via the arm 18 and the arm 18a to stop the vehicle.

FIG. 2 is a rear view of the automotive brake apparatus according to the present invention. As shown in FIG.
Is fixed to the right end 11 of the cover case 12 of the rear axle.

The curved plate 19 of the brake pad 2 attached to the tip of the arm 18a constituting the operating portion 2 fixed to the right end 11 of the cover case 12 presses the frozen road surface 23.

FIG. 3 is a perspective view of an operating portion constituting the automotive brake apparatus according to the present invention. The operating portions 1 and 1a are fixed to left and right end portions 11 and 11a of a cover case 12, respectively. The actuating portions 1 and 1a include a box-shaped fixing member 13, a hydraulic cylinder 14 for controlling a brake pad, an adjusting spring 16 having an adjusting screw 15, and a supporting member 17 having a projecting portion 17a. It comprises a movable member 18 having an arm 18a attached to one end.

As shown in FIG. 3, the hydraulic cylinder 14
Is fixed on the fixed member 13 by a fixed base 14b and a bolt nut 14c. A movable member 18 is connected to a piston 14d constituting the hydraulic cylinder 14 by a connecting pin 22, and the movable member 18 is ,
Projection 1 of support member 17 fixed to fixing member 13
7a so as to be rotatable.

An adjusting spring 16 whose one end is locked by an adjusting screw 15 having an adjusting nut 15a is locked on an upper portion of a movable member 18 rotatably mounted on the projecting portion 17a. At the same time, an arm 18a of the brake pad 2 is mounted below the movable member 18.

The adjusting spring 16 adjusts the pressing force of the brake pad 2 against the frozen road surface when hydraulic pressure is applied to the hydraulic cylinder 14. As a method of adjusting the adjustment spring 16, the length of the adjustment screw 15 is changed by turning the adjustment nut 15a, and the force acting on the movable member 18 is adjusted.

FIG. 4 is a perspective view of a brake pad constituting the automotive brake apparatus according to the present invention. Brake pad 2
Has a plurality of protrusions 21, 21, 21, 21, 21 on the lower surface.
.. Are formed and a curved plate 19 on the upper surface of which a connecting projection 19a is formed, and an arm 18a to which a connecting member 18b having a U-shaped cross section is fixed. ing.

Projecting members 21 and 2 projecting from the lower surface of curved plate 19
Are inclined in the traveling direction of the vehicle. In this way, the inclining is performed so that efficient braking can be performed.

The connecting projection 19a is provided substantially at the center of the upper surface of the curved plate 9, and is provided on the connecting projection 19a.
8a so as to enclose the connecting member 18b,
The connecting plate 20 is inserted to removably attach the curved plate 19 to the arm 18a. In this way, by adopting a detachable structure, the curved plate 9 can be replaced.

Since both ends of the curved plate 9 are curved upward, the curved plate 9 can easily avoid the convex portion of the frozen road surface 23 even if the frozen road surface 23 has irregularities. Thus, the curved plate 9 is not damaged.

FIG. 5 and FIG. 6 are side views showing the relationship between a hydraulic cylinder and an arm constituting the automotive brake apparatus according to the present invention. That is, FIG. 5 shows a state without braking, and FIG. 6 shows a state with braking.

When the brake pedal 7 is not depressed, as shown in FIG.
a and at a position substantially perpendicular to the projection 17a.

However, when the brake pedal 7 is depressed, the piston 14a of the hydraulic cylinder 14 moves in the direction of the arrow a as shown in FIG.
Rotating in the direction of arrow b with the connecting pin 22a as a fulcrum,
The vehicle 18a also rotates in the direction of arrow c, and the vehicle is braked.

FIG. 7 is a rear view of another embodiment of the hydraulic cylinder of the automotive brake apparatus according to the present invention. As shown in FIG. 7, the automotive brake apparatus B of this embodiment has a structure in which an operating portion 1 and a brake pad 2 are provided at a left end 11a. Thus, the right end 11
And, by installing it at the left end 11a, more effective braking can be obtained.

The oil pressure adjusting level-5 mounted on the first oil supply pipe 4a not only adjusts the oil pressure, but also when the brake device for a vehicle is not used in summer.
There is also a function of stopping the hydraulic pressure feed completely and stopping the drive of the automotive brake device. Further, the structure may be such that a driver sitting on the seat 9 can operate the hydraulic adjustment level-5 in a sitting state.

The adjusting spring 16 may be covered with a bellows-like rubber to protect the adjusting spring 16.
