Brake caliper assembly < RTI ID = 0.0 >

The present invention relates to a brake caliper assembly, and more particularly, to a brake caliper assembly that can distribute the lateral torque of the caliper housing during braking from four places by two guide rods and two guide pin bolts, And more particularly to a brake caliper assembly that can be lightened so as to be mountable on a small vehicle such as an electric car.

BACKGROUND ART [0002] Generally, a braking device, which is a braking device of a vehicle, is an important device of a vehicle used for decelerating or stopping a running vehicle, and disk brakes and drum brakes, which are hydraulic brakes, are used.

In recent years, disc brakes have been used more frequently than drum brakes in order to improve the braking performance of a vehicle. This disc brake is a device for braking the vehicle by bringing the brake pads into close contact with the disc.

The disc brake includes a disc rotating integrally with the wheel, and a caliper assembly that presses the brake pad against the disc and brakes the disc by frictional force.

The carrier 12 is provided with the brake inner pad 13 and the outer pad 14 disposed with a disc (not shown) therebetween.

At this time, the brake inner pad 13 is brought into close contact with a disk (not shown) by the operation of the piston 15, and the outer pad 14 is pressed by the reaction force supporting end 16 of the caliper housing 11, (Not shown).

According to the brake caliper assembly 10 having such a configuration, when the piston 15 is operated, the inner pad 13 is brought into close contact with the disk and the reaction force supporting end of the caliper housing 11 16 are brought into close contact with the outer pad 14 to obtain a braking force.

Such conventional brake caliper assemblies are generally made of cast iron in order to reinforce the strength, which is disadvantageous in that they are difficult to be mounted on a small car such as a golf cart (car) or an electric car.

The bracket 110 is preferably formed in a plate shape so as to be fixedly mounted on a vehicle body.

It is preferable that the bracket 110 has a simple shape so as to have compatibility. That is, since the shape of the bracket 110 according to the present invention is formed in a plate shape as compared with the conventional products, it is possible to change the design so that it can be easily compatible with other vehicle types.

A first hole 112 is formed on both sides of the bracket 110 so that a guide rod to be described later can be engaged and a second hole 114 is formed on both lower sides of the bracket 110, It can be used as a fixing ball.

Further, the caliper housing 120 is installed in the bracket 110, and a wheel cylinder 102 is provided at one side thereof and a space portion is formed therein.

The carrier 130 is installed in the space of the caliper housing 120. That is, the caliper housing 120 includes the wheel cylinder 102 at one side corresponding to the brake inner pad 132 and the wheel cylinder 102 at the other side corresponding to the brake outer pad 134. [ A reaction force supporting end 122 is formed so that a reaction force due to the operation of the brake outer pad 134 acts as a surface pressure.

At this time, the reaction force supporting ends 122 are preferably composed of two reaction force supporting ends separated from each other on both sides, and guide pin bolts (to be described later) are disposed outside the reaction force supporting ends 122.

First and second fastening holes 126a and 126b are formed at opposite ends of the caliper housing 120 to fasten the guide pin bolts to be described later. . At this time, one of the second fastening holes 126a and 126b is made of a screw hole so that the guide pin bolt can be engaged.

The carrier 130 includes a brake inner pad 132 and a brake outer pad 134. The brake inner pad 132 and the brake outer pad 134 are disposed in the space portion of the caliper housing 120, (Not shown), respectively.

As shown in the drawing, the brake caliper assembly 100 according to the present invention is provided with two guide rods 140.

The guide rods 140 are fastened to both sides of the caliper housing 120 and corresponding brackets 110 to support the movement of the caliper housing 120 during braking, Is guided to slide on the rod (140).

The guide rod 140 serves to couple the bracket 110 and the caliper housing 120 together and to guide the caliper housing 120 to slide during braking. That is, the guide rod 140 is coupled through the first hole 112 formed in the bracket 110 and the first coupling hole 124 of the caliper housing 120.

As shown in the drawing, the brake caliper assembly 100 according to the present invention is provided with two guide pin bolts 150.

The guide pin bolts 150 are fastened to both sides of the caliper housing 120 and extend through the brake inner pads 132 and the brake outer pads 134 so that the pistons of the wheel cylinders 102, When the brake inner pad 132 is pushed, the caliper housing is supported to compensate for the tendency of the caliper housing to be pulled in the fore-and-aft direction. That is, the guide pin bolts 150 are installed through the brake inner pads 132 and the brake outer pads 134 so as to be fastened to the second fastening holes 126a and 126b formed in the caliper housing 120.

The guide pin bolt 150 guides the brake inner pad 132 and the brake outer pad 134 to slide so that the brake inner pad 132 and the brake outer pad 134 can friction with the disc .

According to the present invention, the lateral torque of the caliper housing 120 generated during braking can be dispersed at four places. Two guide rods 140 for connecting the caliper housing 120 and the bracket 110 and two guide rods 140 installed on the caliper housing 120 to penetrate the brake inner pad 132 and the brake outer pad 134 Side torque can be dispersed in the two guide pin bolts (150).

Accordingly, the present invention has the advantage that the caliper housing 120 and the bracket 110 can be made of an aluminum material, which can be lightened so that the caliper housing 120 and the bracket 110 can be mounted on a small vehicle such as a golf cart (car) and an electric car. That is, the caliper housing 120 and the bracket 110 can be made of aluminum material by dispersing the torque by the guide rod 140 and the guide pin bolt 150.

In addition, the guide pin bolt 150 may be provided with a coil spring 160.

The coil spring 160 serves to restore the brake inner pad 132 and the brake outer pad 134 to the original position after the braking operation and also functions as a brake inner pad 132 and a brake outer pad 134, Thereby suppressing vibration and tremor of the brake inner pad 132 and the brake outer pad 134.

According to the present invention, by providing the guide pin bolts 150, the caliper housing 120 and the bracket 110 can be made of aluminum and can be reinforced. That is, the brake inner pad 132 and the brake outer pad 134 are slidably operated along the guide pin bolt 150, so that they can be made of aluminum.

Therefore, conventionally, since the brake pad is operated to move back and forth on the bracket surface, it can not be made of a material such as aluminum, and it is required to be manufactured only with cast iron having high strength. The present invention, There is a feature that it can be lightened to be possible.

In addition, the present invention also has a feature that, when the piston pushes the brake inner pad 132, the caliper housing 120 can compensate for the force of being stretched in the forward and backward directions. That is, the caliper housing 120 can hold the opening.

In the braking operation, the brake inner pad 132 and the brake outer pad 134 are slid on the guide pin bolt 150 to act against friction with the disk, and when the brake is applied, the bracket 110 and the caliper housing 120 are slid through the guide rods 140 so that the structural weakness of the caliper housing 120 spreading back and forth by hydraulic pressure during braking is transmitted to the guide pin bolts 150 and the guide rods 140 Can be supplemented.

Particularly, according to the present invention, since the coil spring 160 is installed on the guide pin bolt 150, it helps the brake inner pad and brake outer pad to return to their original positions after braking, have.

The technical object of the present invention is achieved by the technical structure as described above, and although it has been described by the limited embodiments and drawings, it is not limited thereto, and it is extremely easy It is obvious that various changes and modifications can be made within the scope of the technical idea of the present invention and the scope of claims of utility model registration described below.
