Disc brake includes a brake disk 1, on opposite sides of which are the brake pads 2 and 3 with friction linings 4, secured to the plates 5. Plate 5 provided with a shoulder 6.

The brake pads 2 and 3 placed on the support plate 7 made in the form of a support plate 8 with 9 stops for the brake pads 3 vertically arranged rack 10 of the support plate, with 11 stops for the brake pads 2 on the bars 12 G-shaped, adjacent to the base plate and covering the brake disk.

One of the shelves 13 of each of the l-shaped beam 12 is parallel to the rack 10 and is connected uma outer grooves 16, parallel to the axis of rotation of the brake disc. Internal grooves 15 are made in the upper parts of the uprights 10 of the support plate 8 and United with them, the shelves 14 of l-shaped bars 12. On the horizontal surfaces of the inner grooves 15, perpendicular to the uprights 10, set his shoulder 6 of the brake pads 3, 2.

The outer grooves 16 in the middle part of the vertical posts 10 and side shelves 13 of l-shaped bars 12. In them placed with a gap ends 17 of the bracket 18, corresponding in shape to the outer grooves 16.

The outer grooves 16 can be made of triangular cross-section with the apex facing toward the axis of the caliper 7.

The ends 17 of the bracket 18 is rotated relative to the base 19 of the bracket 18, so that the upper and lower surface 19a of the base 19 of the bracket 18 are transferred respectively in the upper and lower edges 20 of the ends 17 of the brackets.

In the joints of the base 19 of the bracket with the ends 17 are made of the recess 21 along the height of the bracket to allow movement of the bracket 18 in the axial direction in the area of shelves 13 of l-shaped bars.

In the base plate 8 of the carriage 7 has guide pins 22. The fingers 22, with the possibility of longitudinal and minor transverse personname front brake pads 3.

To the housing 23 of the hydraulic cylinder with their ends 17 is mounted on the bracket 18, covering the brake disk 1 along the chord from the brake pads 2.

The housing 23 of the hydraulic cylinder is equipped with polyamide guide sleeve 25 and the rubber covers 26, which are protruding part of the guide pin 22.

The support plate 7 is fixed to the body of the knuckle (not shown).

In the center of the top plate 5 of the brake pads 2, 3 are made protrusion 27 in the aperture 28 includes an axle 29 on which the swivel is installed spring 30 to tighten shoulder 6 of the brake pads 2 and 3 to the horizontal surfaces of the grooves 15 of the caliper 7.

In the upper part of the housing 23 of the hydraulic cylinder is mounted presser plate pads 31 located in the direction of the axis of rotation of the brake disc and up to the base 19 of the bracket 18. The inner surface of the lining 31 is in contact with the protrusions of the shoulders of the spring 30.

Disk brakes.

With increasing pressure in the hydraulic cylinders of the brake piston 24 and the bracket 18 press the brake pads 3, 2 to the brake disk 1. In this case, brake pads 3,2, leaning his shoulder 6 on the horizontal resolution is to 3,2 towards each other is carried out by moving the piston 24 together with the brake Shoe 3 to one side of the disc 1, and the housing 23 of the hydraulic cylinder and the bracket 18 with the brake Shoe 2 to the other side of the disk 1. The movement of the body 23 of the hydraulic cylinder, the bracket 18 with the simultaneous movement of the pistons 24 is carried out relative to the guide pin 22 mounted in the base plate 8 of the carriage 7.

Pads 2, 3 are fond of disk 1 corresponding to the rotation direction after contact with the brake disc. Thus shouldered 6 brake pads 3 slide on the horizontal surfaces of the inner grooves 15 of the support plate 7, and then block 3 abuts against the upright support 10 of the support plate 8. Shouldered 6 brake pads 2 also slide on the horizontal surfaces of the inner grooves 15, and then block 2 rests on shelf 13 of l-shaped bars 12.

The force from the brake pads 2 is transmitted through the shelf 13 of l-shaped bars on the support plate 8 of the carriage 7, and the brake pads 3 through the vertical rack 10 also on the support plate 8 of the caliper.

This embodiment of the disk brake can reduce its size and to use on cars with transaxles, working with heavy loads.
