Description

DISC BRAKE}

The present invention relates to a disc brake, and more particularly, to a disc brake having a support plate which can reduce the shaking of the friction pad and quickly separate the friction pad from the disc after the braking operation.

In general, a disc brake is a device for braking a vehicle by pressing both sides of a disc rotating with a wheel with a friction pad. The disc brake has a caliper housing and a piston for pressing the friction pads disposed on both sides of the disc toward the disc, and a carrier mounted to the vehicle body for supporting the friction pads and the caliper housing.

The caliper housing is retractably coupled to the carrier by two guide rods coupled to both sides thereof, and the two friction pads are supported on the carrier so as to retract toward both sides of the disk. A pad spring is interposed between the carrier and the friction pad to prevent the friction pad from shaking while supporting the friction pad in a retractable manner. And, the friction pads comprise a support plate for supporting the back of the friction member in contact with the disk.

In such a conventional disc brake, when the driver presses the brake pedal, a braking hydraulic pressure is formed in the master cylinder and transmitted to the piston, so that the two support plates are advanced toward the disc. As the two support plates move forward, the friction pads squeeze both sides of the disk, thereby braking the vehicle.

The above-mentioned disc brake can smoothly drive the vehicle and reduce fuel consumption when the friction pads are quickly separated from the disc after the braking operation is completed. However, the conventional disc brake is supported because the support plate and the pad spring maintain surface contact. When sliding the plate is required a large force and there is a problem that the resistance occurs, there is a problem that the support plate and the pad spring is easily fixed due to the small contact due to the excessive contact area.

Accordingly, an object of the present invention is to provide a disc brake that allows the friction pads to be quickly spaced from the disc after the braking operation.

In order to achieve the above object, a disc brake according to the present invention includes first and second friction pads disposed on both sides of a disc, a caliper housing and a piston for pressing the two friction pads toward the disc, and the caliper housing. And a carrier for supporting the two friction pads, and two pad springs interposed between both ends of the two friction pads and the carrier, wherein each friction pad includes a friction member in contact with the disk, and the friction member. It includes a support plate for supporting, wherein the support plate is characterized in that it comprises a roller installed to enable the rolling motion between the pad spring and the support plate.

Both ends of the support plate includes protrusions protruding from both ends of the support plate to be coupled to the pad spring.

The roller is installed on the support plate, and the support plate has a locking groove to which the roller is inserted and rotated.

The roller protrudes in a semicircular shape from the support plate to roll in contact with the pad spring.

At least one roller may be installed.

Since the roller of the disc brake according to the present invention is rolling friction with the pad spring, there is an effect that the two friction pads can be quickly separated from the disc after the braking operation is finished. Therefore, it is possible to minimize the unnecessary friction between the disk and the two friction pads to reduce the fuel consumption loss of the vehicle.

Figure 2 is a plan sectional view showing the main portion of the disc brake according to the present invention.
3 is a perspective view of a support plate of the disc brake according to the present invention.

Hereinafter, with reference to the accompanying drawings a preferred embodiment according to the present invention will be described in detail.

As shown in FIG. 1, the disc brake according to the present invention is disposed on both sides of the disc 10 for pressing and braking both sides of the disc 10 and the disc 10 that rotate together with the wheel of the vehicle. Caliper housing 20 and piston 30 for pressurizing the first and second friction pads 11 and 12, the first and second friction pads 11 and 12, and the first and second friction pads 11, 12) and a carrier 40 for supporting the caliper housing 20.

The carrier 40 supports the first and second friction pads 11 and 12 to advance and retreat toward both sides of the disk 10. In addition, the carrier 40 supports the caliper housing 20 to retreat in the direction in which the first and second friction pads 11 and 12 are pressed as shown in FIG. 1. To this end, the caliper housing 20 is supported by the guide rods 21 installed at both sides thereof so as to be able to move forward and backward in the guide grooves 41 at both sides of the carrier 40.

As shown in FIG. 1, the first and second friction pads 11 and 12 support the friction members 11a and 12a in contact with the disk 10 and the back surfaces of the friction members 11a and 12a, respectively. Plates 11b and 12b. On both sides of the carrier 40, two pad springs 50 are provided to support both ends of the two friction pads 11 and 12 so as to be buffered, and to guide the retraction operation of the two friction pads 11 and 12, respectively. do.

The pad spring 50 is provided between the carrier 40 and the support plates 11b and 12b to enable smooth movement of the support plates 11b and 12b and to prevent shaking of the support plates 11b and 12b during vibration of the vehicle. do. As shown in FIG. 1, the pad spring 50 has a mounting portion 52 which is bent and extended on both sides of the body portion 51 so as to be caught and supported by the body portion 51 having a flat plate shape and the carrier 40. It is configured to include. And the fixing part 53 is provided on the side of the mounting part 52 is fixed to the carrier 40. Meanwhile, the pad spring 50 is coupled to the support plates 11b and 12b described later.

Protrusions 100 are provided on the support plates 11b and 12b and are coupled to the mounting portions 52 of the pad spring 50. And the carrier 40 is provided with a sliding portion 43, as shown in Figure 1 is coupled to the mounting portion 52 of the pad spring 50. In addition, the mounting part 52 and the sliding part 43 are each in the shape of a "c". Therefore, the friction pads 11 and 12 may be spaced apart from the disk 10 because the protrusion 100, the mounting portion 52, and the sliding portion 43 are slidably coupled to each other.

The protrusions 100 of the support plates 11b and 12b are provided with rollers 77a and 77b for smooth sliding operation. As shown in Fig. 2, the rollers 77a and 77b are mounted to the engaging grooves 75a and 75b provided at the upper end and side ends 101a and 101b of the support plates 11b and 12b. The outer diameters of the rollers 77a and 77b are smaller than the radius of the locking grooves 75a and 75b. The cross sections of the rollers 77a and 77b have a circular shape, and the cross sections of the engaging grooves 75a and 75b have an arc shape. Therefore, since the rollers 77a and 77b are rotated with the pad spring 50, the support plates 11b and 12b may be smoothly rolled during braking.

The rollers 77a and 77b may be spherical or cylindrical. In addition, it is preferable that at least one roller 77a or 77b is provided so that the pad spring 50 and the support plates 11b and 12b have a smooth rolling motion.

The rollers 77a and 77b protrude in a semicircular shape so as to be in contact with the pad springs 50 and rolled. That is, as shown in FIG. 2, a part of the rollers 77a and 77b is formed higher than the surfaces of the support plates 11b and 12b. Therefore, the pad spring 50 and the support plates 11b and 12b may be in line contact, thereby preventing the pad spring 50 and the support plates 11b and 12b from sticking together.

The locking grooves 75a and 75b have a cross-section of the letter “C” in shape so that the rollers 77a and 77b can rotate. That is, the cross-sections of the locking grooves 75a and 75b are circular arcs further advanced in a semicircle as shown in FIG. 3. Therefore, since the rollers 77a and 77b are pressed to the locking grooves 75a and 75b and rotated to be rolled, the pad spring 50 and the support plates 11b and 12b may be prevented from sticking together. have.

When the support plates 11b and 12b are mounted to the disc brakes, the rollers 77a and 77b perform rolling motion between the support plates 11b and 12b and the pad spring 50 as shown in FIGS. 2 and 3. Therefore, a large force is not required when sliding the support plates 11b and 12b, and thus the resistance is reduced. Therefore, the vibration generated after the brake braking can be reduced.

In addition, since the support plates 11b and 12b are provided with rollers 77a and 77b and are in linear contact with the pad spring 50, the contact area between the metals is reduced and the probability that corrosion can occur is reduced. And the pad spring 50 can be prevented from sticking.

In addition, the support plates 11b and 12b are designed to prevent unnecessary friction between the disk 10 and the two friction pads 11 and 12 since the friction pads 11 and 12 can be quickly separated from the disk 10 after brake braking. Reducing it allows the vehicle to run smoothly and reduces the fuel economy of the vehicle.
