(54) CAR DISC BRAKE
one
This invention relates to the automotive industry, in particular to automobile disc brakes.
Closest to the proposed technical solution is a disc j vehicle brake containing a pair of pair holders to which control means are attached for pressing at least one brake pad to the brake disc, with the indicated brake jq per block made of a friction lining associated with base plate rounded off on the edges of the hole, drilled in the holder of the brake pair by means of | g at least one V-shaped guide cross-section in cross-sectional cross-section the contact surfaces of the inner surfaces with the corresponding edges of the hole, and the outer surfaces with the jurassic plate, one of the butts of the V-shaped key located in the direction of the inside of the brake, while the other shelf is perpendicular to radial plane of 25
the braking metrics are under the sharp edge, to the first shelf; at the same time, at least one anti-noise spring is connected to the support plate, supported on the outer surface of the key shelf, perpendicular to the indicated plane of symmetry 1.
However, the known brake is characterized by insufficient reliability, since during its operation a spontaneous ejection of brake pads is possible through the hole in the holder, and the difficulty of replacing brake pads when the friction linings are worn.
The purpose of the invention is to increase reliability and facilitate the replacement of brake pads.

Claims (5)
[1]
The goal is achieved in that in the disc brake of the car, the key is accomplished with at least one groove on the shelf extending in the direction of the inner part of the brake to ensure that the backplate is removed through the holder in the brake pair when the supporting plate is located opposite to 397 of the specified groove, the key itself is mounted to move along the corresponding edge of said hole in a direction parallel to the axis of the brake disc, for installation in the fixed position of the support plate, in which the groove is offset relative to the support plate, and in a position in which the groove is located opposite the support plate. In addition, the brake is provided with locking means for holding the spoil in position for fixing the support plate, made in the form of at least one pin passed through a hole made in the key and pressing the key to the stop means associated with the holder of the brake pair, In order to extract a second support plate in a shelf extending in the direction of the inner part of the brake, a second groove is made, the width of which is greater than the thickness of the support plate. In this case, both grooves are shifted in the same direction by the same distance with respect to the support plates of the corresponding brake pads with the pin locked and unworn friction linings. FIG. 1 shows a disc brake of a car, top view with partial cut-out; in fig. 2 - the same, with the position of the arm, allowing the brake pads to be removed; in fig. 3 is a section A-A in FIG. one; in fig. 4 - section B - B in FIG. 2 in FIG. 5 is a sectional view BB in FIG. 2; in fig. 6 - key, plan view. The disk brake of the vehicle (FIG. 1) has a holder of a brake pair in the form of a movable cramp 1, mounted with studs 2 on a fixed bracket (not shown). Controls consisting of a hydraulic cylinder 3 are connected to the bracket 1 and are designed to press the friction elements 4 and 5 respectively to the surfaces 6 and 7 of the brake disc 8. The friction elements 4 and 5 are fixed on the support plates 9 and 1 O and form brake pads with them . Bracket 1 (Figs. 1 and 5) has a rectangular opening 11, the circumferentially spaced edges 12 and 13 of which support plates 9 and 10. On the edge 13 there is a V-shaped cross-section 14, one shelf 15 of which is directed to the inner part of the brake, and the other 16 is perpendicular to the plane of symmetry of the brake. 9 The key 14 (FIG. 6) has .two grooves 17 and 18 on the shelf 15 and a hole 19 for the pin (not) fixing the position of the key relative to; the stop p (not shown) associated with the clip i. Shelves 15 and 16 are located at an acute angle to each other, equal to the angle of the surfaces of the edge 13, while the wafers of the same profile are made on the support plates. The brake is equipped with anti-noise springs 20 and 21 resting on co-supporting support plates and shelf 16 splines 14. In the working position (Fig. 1), the grooves 17 and 18 are offset relative to plates 9 and 10, the key 14 is fixed and prevents the plates 9 and E from being removed from the hole 11 If it is necessary to remove the brake pads, the pin that goes into the hole 19 is removed. The key 14 moves to align the grooves 17 and 18 with the plates 9 and 1 O, and the springs 21 and 20 rotate the plates 9 and 1 O with respect to the edge 12 and can be freely removed. new brake The pads are reversed. The use of the brake of the proposed design allows to simplify the installation and disassembly of brake pads and ensures reliable mounting during operation. Claim 1. A car brake containing a brake holder, a pair to which control means are attached to press at least one brake shoe to the brake disk, said brake shoe being filled from a friction lining associated with a support plate. the circumference of the edges of the hole, made in the holder of the brake pair by means of at least one; A yoke-shaped guide key in contact with the inner surfaces with the corresponding edge of the aperture, and the outer surfaces with the support column, one I5 of the V-shaped key being located in the direction of the inner part of the brake, then as a friend, the shelf is perpendicular to the radial plane of symmetry of the brake at an acute angle to the first shelf;
at least one anti-noise spring supporting the outer surface of the key shelf perpendicular to the specified symmetry plane, characterized in that, in order to increase reliability and facilitate the replacement of the brake pads, the key is provided with at least one groove on the shelf extending in the direction of the inner parts of the brake to allow the support plate to be removed through the hole in the holder of the brake pair when the support plate is located opposite the specified groove, and the key itself is set to tim along the corresponding edges of said apertures in a direction parallel to the brake disc axis, for mounting in the position fiksashsh backplate, wherein the groove is offset relative to the reference n las slime, and the position at which the groove is situated opposite the base plate.
[2]
2. The brake pb p. 1, that is, so that it is equipped with locking means to hold the key in the locked position from the jib plate.
[3]
3. The brake according to claim 2, of which is with the clutch means made in the form of at least one pin passed through a hole made in the key and pressing the key to the stop means related
with brake pair holder.
[4]
4. The brake according to claim 1, in respect of the fact that, in order to remove the second support plate, in a shelf extending in the direction of the inner part of the brake, a second groove is made, the width of which is greater than the thickness of the support plate.
[5]
5. The brake according to Clause 4, of which there are. that both grooves are displaced in the same direction by the same {toc position relative to the bearing plates of the corresponding brake pads with the pin locked and unworn friction linings.
