    1 The invention relates to mechanical engineering, in particular to the automotive industry. A disc brake is known, which contains a drive, a fixed support, a brake disc with a brace enveloping it, a rigid plate fixed on a fixed support in two axial columns, and friction elements fixed on a fixed support ij. A disadvantage of this device is the difficult disassembly of the friction elements due to the fact that the clamps do not have the ability to move along the arc and therefore the disassembly of the friction elements can be carried out only in the axial direction from one and the other disk sides. The closest to the proposed technical essence and the achievable effect is a disc brake containing a drive, a fixed support on which one of the ends of the brake disc of the caliper is pivotally fixed. The staple has the ability to facilitate the disassembly of the friction elements to move along an arc. In the working position, the bracket is fixed by means of its fastening - by a locking element located between the bracket, and a fixed support in the recess of the latter, the locking element being formed by a removable tongue 2. The disadvantage of this device is poor operating conditions, since the replacement of the friction elements is a complex operation that requires additional dismantling of the sliding key by axially displacing the latter after previously removing the two safety pins. In addition, the additional fastening of the locking element cannot contribute to the reliability of its fastening. The aim of the invention is to improve the operating conditions by improving the reliability of fastening the bracket and simplifying the dismantling of the friction; items. The goal is achieved by the fact that in the disc brake containing the drive, fixed support, Scoop and friction elements attached to the bracket, the last one end is pivotally mounted in the axial column on the fixed support, and the other 3 can move along the fixed support with the recess and the supporting face in it, the moving end of the bracket and the fixed support in its recess, the locking element is axially mounted, and the recess by the outer edge of the supporting face does not match the radial inclined surface the movable support and forms with it the means of holding and fixing the locking element and the bracket; the means of holding the locking element are executed on the bracket in the form of at least two radially spaced stops with abutment surfaces arranged in a plane parallel to the plane of movement of the bracket; and the locking element is made of an elastic material in the form of an elongated element with an axial support surface and secured by means of holding at the end of the bracket with the possibility of elastic movement in the plane, tangent to the movement of the bracket, with the abutment surfaces of the lugs of the holding means facing each other and parallel to each other. In addition, the bearing surface of the fixed support is made flat and parallel to the plane of the stop. stop surfaces of the retention means of the closure member. A blind hole is made in the bracket and one of the ends of the locking element is fixed in it. One of the ends of the locking element is provided with means of engagement, a through hole is made in the bracket, and the end of the locking element is fixed in it with the possibility of fixation by means of engagement. The locking element can be made of metal spring wire of circular cross section. FIG. 1 schematically shows a disk brake, top view; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. one; in fig. 4 - section. Bb in fig; 3; in fig. 5 is a detailed view showing the locking element of the disc brake, which he takes when assembling the brake; in fig. 6 is a partial top view of an embodiment of a disc brake locking member; in fig. 7 version of the implementation and installation of the locking element.
    The disk brake (figs. 1-5) contains a bracket 1., mounted for movement on a fixed support 2. The drive means are mounted on the bracket 1 and include a hydraulic brake actuator 3 directly acting on the friction elements 4 and 5. The drive contains a piston 6, the support plates 7 and 8 and the cylinder, which plays the role of the clip 1. The friction elements are located on both sides of the brake disk 9 with the ability to interact with its brake surfaces 1 O and 11.
    As shown in particular in FIG. 2 and 3, the fixed bearing 2 is provided with a central opening, the edges of which are supported, when fastened and moving, the support plates 7 and 8 of the friction elements 4 and 5 in such a way that the fixed support 2 forms an optic element for the latter.
    Bracket 1 is installed with the ability to move along an arc on a fixed support 2 by means of an axial column 12. In this case, in particular, it is shown (Fig. 1) that column 12. rigidly connected to the fixed support by the threaded connection 13. Column 12 is moved in the hole 14 ,. performed on one of the ends 15 of the bracket 1 For locking the bracket 1 in the working position in the design of the disc brake, a locking element 16 is provided, located in the axial direction with the bracket 1 and the fixed support 2. The locking element 16 is formed by an elastic element made in the form of metal cylindrical spring wire. The main branch 17 of the locking element 16 is located in a plane parallel to the plane tangential to the movement of the bracket 1. The locking element 16 is fixed to the bracket 1 by one of its ends 18. The end 18 of the locking element 16 forms together with the main branch 17 placed on the end of the movable bracket end 1 angle equal to EO of FIG. 4) and tightly planted in a blind hole 19, made in the protruding part W of the bracket 1. As can be seen from FIG. 1, the main branch 17 of the locking element 16 is provided with a curved part or a supporting protrusion 20 having the shape of a letter S. The locking element 16 is supported by its projection 20 on the end face 21 of the bracket and resiliently presses against the said end and the recess 22 formed on the shoulder 23 of the fixed support 2 The recess 22 comprises a flat bearing surface 24 parallel to the axis of the brake disc 9. In this case, the main branch 17 of the locking element 16 is held in contact with the supporting surface 24 by means of a spring 25. The spring 25 is a spring from a sheet Hoists that are attached to bracket 1 and which rests on the friction elements 4 and 5. The ends 26 and 27 of the branches of the spring 25 rest on the inner surface 28 of the bend of the bracket 1 to distribute the support force, whatever the shape of the bend of the bracket. The spring 25 is fixed on the top of the bracket 1 by means of its central part 29, which is elastically inserted into the opening 30 of the bend of the bracket 1. The spring 25 is thus fixed to the bracket and remains rigidly connected to this latter when disassembling the brake. As shown in FIG. 2, the spring 25 rests on the central parts 31 of the outer upper edges of the support plates 7 and 8 of the friction elements and moves the bracket 1 in the direction indicated by the arrow G. Thus, the spring 25 performs a dual role: firstly, it holds the main branch 17 of the locking element I6 in contact with the support surface 24; secondly, it acts as a damper of the schum for friction elements 4 and 5 and facilitates movement along the arc of the bracket I. According to the invention, means are provided for holding the element 16. These means are formed by two flat surfaces 32 and 33 filled on two protrusions 34 and 35, made at the same time integer with bracket 1 and coming from the last 21 strca
    The flat surfaces 32 and 33 of FIG. 2 and 3) are parallel to the plane of movement of the locking element 16 and are separated by a distance of 2, slightly exceeding the diameter of the wire forming the locking element 16, to ensure that this element moves between surfaces 32 and 33. When the bracket takes its normal working position, surfaces 32 and 33 are parallel to the support surface 24 formed on the shoulder. 23. Fixed support (Fig. 4). In order to avoid too large deformations of the main branch 17 of the locking element 16, a support surface 36 is provided on the bracket 1, parallel to the surfaces 32 and 33. and formed on an additional protrusion 37, which is integrally formed with the bracket 1. Thanks to the supporting surface 36, end 38 the main branch 17 cannot deform in the direction indicated by the arrow AND in FIG. 4. Thus, a random displacement of the locking element 16 is prevented under the action of a load applied to the bracket 1 by a spring 25. D., safety, in addition, a safety pin 39 is provided which fixes the end 38 of the main branch i 7 relative to the protrusion 37. The pin 39 elastically installed hole 4Q, drilled in the protrusion 37, Between the end 41 of the shoulder 23 and the end 42 of the additional protrusion 37, the functional gap X (Fig; 1) is performed. This functional gap provides the ability to rotate the bracket 1 around the axial column 12 when assembling the brake. After several brakes, gradual wear of the friction element 5 causes a gradual displacement of the bracket 1 in the direction indicated by the arrow E (Fig. 1 and 4), with the end face 42 moving in the same direction. Due to this displacement, the side end 42 and the abutment surface 36 gradually occupy a position opposite the flat support surface 24 formed on the protrusion. This prevents any accidental displacement of the bracket 1 in the direction indicated by the arrow D, even in the event of a rupture of the locking element 16. The shoulder 23 of the fixed support 2 is reduced by the inclined surface 43 (Fig. 2). The inclined surface 43 directs the movement of the main in, the 17 of the locking element 16, overcoming its own elasticity when the bracket is rotated to its normal working position around the axial column 12. The inclined surface 43 is in contact with the supporting surface 24 with the possibility of fixing and fixing means brackets 1. 536. FIG. 6 and 7 show an embodiment of the invention, which differs mainly from the first embodiment by fastening the end of the locking element on the bracket. The end 18 of the locking element 16 is formed by a cylindrical part 44 of metal wire, placed in a through hole 45, made in a protruding part of the bracket 1. The end 18 is thus secured in the through hole 45 and elastically held against the support surface 24. In addition, the end 18 provided with locking means 46, interacting with the protruding part of the bracket in order to prevent the cylindrical part of the end 18 from being accidentally displaced from the through-hole 45. The locking means 46 are formed by a loop made at the end of the cylinder Indra part 44, extreme branch 47 which can interact with the side surface 48 formed on the protrusion of the bracket 1. The locking element 16 can be fixed on the fixed support 2. In this case, the inclined surface 43 should be formed on the bracket 1. In addition, the support surface 24 may contain a second support surface, the surface, which allows the Kitsu to avoid the falling out of the clip 1 in the direction indicated by the arrow C. The disc brake works as follows. When creating pressure in the cylinder of the actuator 3, the piston 6, moving, acts on the friction element through the support plate 7. At the same time, the pressure in the cylinder causes the clamp 1 to move in the direction opposite to the movement of the piston 6. This allows the impact on the friction element through the plastics support 8. The brake is activated. The brake assembly is performed as follows. Having installed the friction elements 4 and 5 on the movement surfaces of the non-falling support 2, move the bracket 1 along column 12 until it is above the friction elements. Then, thanks to the functional clearance X, the bracket can be turned around column 12 in the direction indicated by arrow C in FIG. 2. At this rotation, as indicated by the arrow W, the locking element 16 describes a part of the circumference in order to come into contact with the upper part of the inclined surface 43. At the same time, the opening 30 of the spring 25 comes into contact with the upper central parts of the supporting part plates 7 and 8 of the friction elements 4 and 5. The operator must then apply additional force to the bend of the bracket I in the direction indicated by arrow C in order to compress the spring 25 and cause the main branch of the locking element 16 to move along the inclined surface 43 and b direction, decree nnom arrow A (FIG. 1). Due to the combined movement of the main branch 17 in directions C D, this branch is set to the extreme position shown in FIG. 5, which it takes before the clip reaches its normal working position, i.e. In order for the branch to come into contact with the supporting surface 24 and prohibit, thus, the brace is in its working position. In this position of the base. The branch 17 rests elastically on the support surface 24 and is kept in contact with it by the action. spring 25. The safety pin 39 is installed in the hole 40 in the bracket 1. When the operator decides to replace the friction elements, he acts as follows. After the safety pin 39 is removed, the operator presses the main veg 17 of the locking element 16 in the direction indicated by the arrow D, I will act on this branch at the point located between the protrusion 35 and the shoulder 23 of the fixed support 2, resting on the support 2. With the release the main branch 17 it moves to. the direction opposite to the direction shown by arrows L (Fig. 2). This movement occurs automatically under the action of the elastic load created by the spring 25, as soon as the main branch 17 has passed the end edge of the inclined surface 43. The operator in this case can completely rotate the bracket I in the direction indicated by the arrow D and make the replacement of the friction elements. When these friction elements are replaced, the operator rotates the bracket in the direction indicated by arrow C in the manner described.
