Description

DISC BRAKE}

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

Disc brake is a device for braking the vehicle by pressing both sides of the disk rotating with the 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 support the friction pad in a retractable manner and to prevent the friction pad from shaking.

The pad springs support the upper and lower ends of the friction pads in a bufferable manner to prevent the friction pads from shaking up and down (radial direction of the disk). However, these pad springs have a limit in mitigating such tremor when the friction pads tremble in the horizontal direction (the direction in which the disk rotates).

In addition, the 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. In the conventional disc brake, even after the brake is released, unnecessary contact between the friction pads and the disc can occur. There was a problem.

The present invention is to solve such a problem, an object of the present invention is to minimize the phenomenon that the friction pads shake in the right and left direction (direction of rotation of the disk), it is possible to quickly separate the friction pads from the disk after the braking operation It is to provide a disk brake to make sure.

Disc brake according to the present invention for achieving this object, the inner and outer friction pads respectively disposed on both sides of the disk, the caliper housing and the piston for pressing the two friction pad toward the disk, the caliper housing and the two friction And a carrier for supporting the pads, and two pad springs interposed between the two friction pads and between the carriers, wherein each pad spring is configured to buffer each of the body portion and upper and lower portions of the two friction pads. Upper and lower support portions each bent and formed on the upper and lower portions of the body portion, respectively, and are provided at both ends of the body portion, respectively, and are bent to press both ends of the two friction pads in the rotational direction of the disk and in a direction spaced from the disk. It characterized in that it comprises a molded two side end support.

Each of the friction pads includes a friction member in contact with the disk and a support plate for supporting the friction member, and the support plate includes locking grooves formed at both ends thereof so as to enter and be caught by the side end support of the pad spring. Characterized in that.

The side end support part may include a first extension part bent toward the rear surface of the pad spring body part, a second extension part bent outwardly from the first extension part to maintain an acute angle with the first extension part, and the support plate. And a third extension part bent from the second extension part to enter the locking groove, and a locking part bent at an end portion of the third extension part to be caught by an inner surface of the support plate.

The disc brake according to the present invention minimizes the phenomenon that the two friction pads swing in the left and right directions (the direction in which the disk rotates) because the side end supporting portions of the pad springs press both ends of the two friction pads in the rotational direction (lateral direction) of the disk. It can work.

In addition, the disc brake according to the present invention has an effect of rapidly separating the two friction pads from the disk after the braking operation is finished because the side end support of the pad spring presses both ends of the two friction pads away from the disk. . 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.

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, inner and outer friction pads 11 and 12, and caliper housings for pressurizing the inner and outer friction pads 11 and 12 and the inner and outer friction pads 11 and 12. And a carrier 40 for supporting 20.

The carrier 40 supports the inner and outer friction pads 11 and 12 to retract toward both sides of the disk 10. In addition, the carrier 40 supports the caliper housing 20 to advance and retreat in the direction of pressing the inner and outer friction pads (11, 12). 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.

The inner and outer friction pads 11 and 12 respectively include friction portions 11a and 12a in contact with the disk 10 and support plates 11b and 12b for supporting the rear surfaces of the friction portions 11a and 12a, respectively. . 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.

1 and 2, the pad spring 50 has a flat body portion 51 and a mounting portion that is bent and extended toward the rear surface of the body portion 51 so as to be caught and supported by the carrier 40. 52 is provided. In addition, the pad spring 50 is formed by bending the upper support 53 and the lower support 54 respectively bent and formed on the upper and lower sides of the body 51 so as to buffer the upper and lower portions of the two friction pads 11 and 12, respectively. And, respectively, formed at both ends of the body portion 51 and bent to press both ends of the two friction pads 11 and 12 in the rotational direction of the disk 10 and in the direction of spaced apart from the disk 10. The side end support part 55 is provided. In addition, locking grooves 13 are formed at both ends of the support plates 11b and 12b of the friction pads 11 and 12 so that the side end supporting portions 55 of the pad springs 50 may enter and be caught.

Specifically, as shown in FIGS. 2 and 3, the side end support part 55 is outside from the first extension part 55a and the first extension part 55a which are bent and extended toward the rear surface of the pad spring body part 51. Bent from the second extension part 55b to extend into the second extension part 55b to maintain an acute angle with the first extension part 55a and to enter the locking groove 13 of the support plates 11b and 12b. The extended third extension part 55c and the engaging part 55d bent by the edge part of the 3rd extension part 55c so that the inner surface of the support plates 11b and 12b may be caught may be included.

When the pad spring 50 is installed on the carrier 40 and two friction pads 11 and 12 are installed thereon, as shown in FIG. 3, the side end supporting portions 55 on both sides of the pad spring 50 are provided. It enters and is caught by the engaging groove 13 formed at both ends of the support plates 11b and 12b of the friction pads 11 and 12.

As shown in FIG. 3, the pad spring 50 presses a direction (arrow A direction) in which the disk 10 rotates both ends of the two friction pads 11 and 12. In this state, the two friction pads 11 and 12 may be swayed laterally, that is, the two friction pads 11 and 12 may be shaken in the rotational direction of the disk 10.

In addition, since the pad spring 50 presses the two friction pads 11 and 12 in the direction (arrow B direction) which normally separates the two friction pads 11 and 12 from the disk 10, the two frictions after the braking operation is completed. The pads 11 and 12 can be quickly spaced apart from the disk 10. This can minimize unnecessary friction between the disk 10 and the two friction pads 11 and 12, thereby enabling smooth running of the vehicle and reducing fuel consumption loss of the vehicle.
