The invention relates to disc brakes of automobiles and, in particular, to the site of disc brakes is at the friction elements (brake pads), ends of which are located in the element providing resistance to brake the moment, and are in sliding contact with him. This element may be stationary support, a movable support or even stationary support element. Disc brakes also contain a control means (wheel cylinder) to move the friction element into contact under load with the corresponding side of the brake disc.Known friction elements (for example, the application FR-A-2,330.916), the opposite ends of which have a rounded surface, which moves in sliding contact with a corresponding rounded surface is performed on the element resisting torque (brake) moment, with one of the curved surfaces is convex and the other concave.In the disk brake of this type (application EP-B-0, 002.399), the opposite ends of the brake pads are located in the element (the caliper), resisting torque, and is in sliding contact with him. The caliper is provided with a control means to move the brake pads into contact under load with the corresponding side of the brake disc. At least one to whom ntact with a corresponding rounded surface, performed on the caliper, with one of the curved surfaces is convex and the other concave. The convex curved surface has a smaller radius of curvature than the concave surface. Brake pad set caliper with a preset limit gap so that it can move in an arc between the first and second extreme positions in which, respectively, its first and second ends in contact with the corresponding part of the caliper, depending on the direction of rotation of the brake disc. Disc brake has an elastic element to bias the brake pads in an arc from the first extreme position in constant contact with the rounded surface of the caliper.Brake pad moves in the opposite curved surface of the caliper every time when the disk brake, to prevent the formation of deposits on contact of the rounded surfaces of the pads and caliper and automatic cleanup.Such a disk brake operates satisfactorily during normal operation of the vehicle. However, when the wheel of a vehicle equipped with such a disk brake, is subjected znachitelyonaja, inertia brake pads may exceed the pressure exerted on it mentioned elastic element so that the Shoe will move relative to the caliper, because it is installed with a gap. Under such conditions, when the disk brake is activated, the block is not on one of the end positions in which it should be, and when braking the vehicle will be hard to collide with the caliper. Strong blows of the brake Shoe, in addition to creating a strong noise may degrade the performance of the brakes and reduce its service life.The aim of the invention is the creation of a node of the disk brake comprising a friction element (pads) and springs, which does not have these disadvantages.In accordance with the invention, the spring site disc brakes are made of metal wire and has an active part located in the slot in the end of the friction element having a convex rounded surface, and the reactive part that interacts with the edge of the concave curved surface of the caliper.The active part of the spring exerts pressure on the carrier plate of the friction element (brake pads) with the force IMessage disk and tangential component in the direction of rotation of the disk, corresponding to the forward movement of the vehicle.Through appropriate selection of the magnitude of the force with which the spring exerts pressure on the friction element, the latter will always take the first extreme position, regardless of the pressures being imposed on the wheel of a vehicle, equipped with a disk brake having a node consisting of a friction element and springs made in accordance with the invention.In Fig. 1 shows host disk brake comprising a friction element and springs made in accordance with the present invention, a front view;
in Fig. 2 - node shown in Fig. 1, a side view,
in Fig. 3 is a front view of the node shown in Fig. 1, is installed in the element resisting torque (brake);
in Fig. 4 is a perspective view of the spring of the node shown in Fig. 1;
in Fig. 5 is a modification of the spring shown in Fig. 4, a top view;
in Fig. 6 - part of Fig. 3, in an enlarged scale.In all the figures the same elements are denoted by the same position.In Fig. 1 shows host disc brakes, with the example, by using a binder (glue) or rivets, friction linings 14. The front 16 and rear 18 the ends of the friction element 10 have rounded surfaces 20 and 22, respectively, and are lengthening the bearing plate 12, which does not have the friction material. Rounded surfaces 20 and 22 form the edges of these extensions.The friction element (block) 10 is used in a disc brake, contains (Fig. 3) stationary element (caliper) 24, which is attached to a stationary part of the vehicle and has a resistance torque (braking) torque. The fixed element 23 is U-shaped and covers a part of the brake disc 26, which is fixed on the element of the vehicle, rotating together with one of its wheels. The stationary element 24 has two cut-out 28, each of which is located on one side of the disk 26 (Fig. 3 shows only one cutout 28). In the cut caliper (fixed element) are arranged to move the brake pads 10, the friction pads 14 which are positioned against the respective sides of the disk 26.Each notch 28 of the support plate 24 has a front 30 and rear 32 side rounded surface, with which cooperation and 10. The definition of "front" and "rear" correspond to the direction of rotation of the brake disc 26, as shown by the arrow a in Fig. 3, when the vehicle moves forward. Rounded surfaces 20 and 22 are convex surfaces, and opposing rounded surfaces 30 and 32 is concave surfaces, the radius of curvature of which at any point is greater than or equal to the radius of curvature of the convex surfaces 20 and 22, so that the brake pad 10 is located in the support plate 24 with a preset limit gap B.Brake pad 10, which is located in the corresponding groove of the caliper, is under load, which creates a spring 40. More specifically, at least one end of the brake pad has a through hole. In the shown example embodiment of the invention the ends 16 and 18 of the brake pads 10 have respective holes 34 and 36 to provide its symmetry during manufacture, i.e., to ensure the interchangeability of the inner and outer pads. The spring 40 is made of metal wire and is located in the rear end 18 of the brake pads. The spring has an active part 42, passing through the hole 36, and a reactive part that interacts with the concave edges rounded piny each other and the active portion 42 and connected with the latter by means of two bridges 48 and 50, respectively.In the example shown in Fig. 1 - 4 and 6, the active part of the spring 42 are also two branches 42a and 42b.In other words, the spring 40 is made of cut metal wire, bent in half in the middle part. Metal wire in place of its curve has a U-shaped portion 52 connecting the one ends of the two branches 42a and 42b forming the active portion 42 of the spring. The other ends of the branches 42a and 42b are arranged at right angles respectively to the bridges 48 and 50, which are located in the same plane and at right angles respectively to the branches 44 and 46 forming the reactive part of the spring.To retain the spring 40 on the friction element 10 at least one of the branches 44, 46 of the reactive part can be bent at a right angle end 54, 56 located in the same plane. The ends 54, 56 of the branches are bent in the direction of the U-shaped connecting part 52. Branches 42a, 42b, 44 and 46 have a length slightly larger than the thickness of the end 18 of the carrier plate 12 of the friction element 10. Jumper 48 and 50 and the ends 54 and 56 prevent rotational movement of the spring 40 relative to the friction element 10, and the active portion 42 located in the hole 36, prevents radial displacement of the spring otnositelnaya part 52 can be bent so that that it was located at right angles to the plane containing 42 active and reactive 44, 46 parts of spring and jumpers 48, 50. As a result, the connecting portion 52 will also prevent rotational movement of the spring relative to the friction element 10, as jumpers 48, 50.Another form of the spring 40 shown in Fig. 5. Spring is also made of cut metal wire and the length of its Central part is slightly greater than the thickness of the end 18 of the carrier plate 12 of the friction element 10. Spring also has an active part 42, which passes through the hole 36 and is at right angles to the bridges 48 and 50. The jumpers are located at a right angle and in the same plane with the branches 44 and 46 forming the reactive part of the spring 40.The branches 44, 46 may also be bent at right angles, the ends 54, 56 directed towards the active portion 42 of the spring and ensures retention of the latter on the friction element 10.Having clarified the design of the friction element (brake pads) Assembly with spring, it is easy to understand the operation of the disc brake. Brake pad 10 in Assembly with the spring 40 is located, as shown in Fig. 3 and 6, in the item (caliper) 24 providing soprotivlenie funds. The caliper includes a control means (wheel cylinder), not shown for clarity, for disc brake wheels. In Fig. 3 and 6 shows the inner brake pad, i.e., pad located on the inner side of the brake disc 26. Needless to say, the following explanations apply to the outer brake pad, i.e., the block located on the outer side of the brake disc 26.When a node is disc brake, consisting of brake pads and springs, is distributed in the support plate 24 and is not used in the work, its various parts occupy the positions shown in Fig. 3 and 6. In particular, the spring 40 is in a pre-tensioned state, its reactive part, consisting of two branches 44 and 46 is in contact with the concave curved surface 32 of the support plate 24, and the active portion 42 exerts pressure on the wall of the bore 36, fulfilled in the end 18 of the carrier plate 12 having a convex rounded surface. The concave surface 32 of the support plate 24 has a limited length, i.e., its size is limited to flat end sections 60 and 62 (Fig. 6), which are based on the branches 44 and 46 of the reactive part of the spring 40. The distance between the branches 44 and 46 more CR> As the spring 40 is pre-sent condition between the flat end sections 60 and 62, limiting the length of the concave rounded surface 32, and the wall of the bore 36, the branches 48 and 50 occupy such a position in which they form, for example, in the plane of Fig. 6, an acute angle, the vertex of which is located in the area of the active part 42.Therefore, the active portion of the spring will exert pressure on the wall of the bore 36 with a force F, directed along the bisector of this angle. Force F is tangential and radial components that are perpendicular to each other. The radial component of this force is directed to the outer side of the disc 26 relative to its axis. Under the action of this component of the convex curved surface 22 is held in contact with a concave rounded surface 32 at the point most remote from the axis of the disk 26.The tangential component of the force F is directed in the direction of rotation of the disk, corresponding to the forward movement of the vehicle (Fig. 3 is the direction shown by the arrow a). Under the action of this component of the convex surface 22 is shifted in the circumferential direction from the concave surface 32 so formed is carried out in contact with the bottom part of the concave rounded surface 30 of the support 24.When the vehicle is in forward direction and pressing the driver on the brake pedal, the brake fluid is supplied under pressure to the wheel brake cylinder (not shown), which presses the carrier plate 12 with a friction lining 14 and one side of the brake disc 26. Another support plate with the friction lining is pressed against the opposite side of the drive using another wheel brake cylinder.When the friction pad 14 is pressed against the disk, which rotates in the direction of the arrow A, the corresponding forward movement of the vehicle, brake pad 10 under the action of the braking force is shifted to the right in Fig. 3 and 6. Due to the special form of springs and brake pads this braking force acts in the same direction as the force F applied by a spring to the brake Shoe with the off position of the disk brake. Therefore, during braking of the vehicle brake pad 10 moves in an arc in the extreme position which it had occupied before the brake.From this it follows that the non-working position of the node of the friction element/spring made in accordance with the invention, precisely for the in the case of large loads, for example, if significant vertical accelerations of the wheels when the vehicle is on the road are in poor condition, or even in roadless areas.In contrast, when the vehicle is in the reverse direction, i.e., during reverse travel, the speed generally is low and therefore the wheel is not subjected to the above-mentioned loads. The site of the friction element/spring in this case is in the off position, shown in Fig. 3 and 6. During braking, when the friction pad 14 is pressed against the disk 26, the friction element 10 under the action of the braking force is shifted to the left in Fig. 3 and 6.In this case, the braking force is directed opposite to the tangential component of the force applied by spring 40, i.e., it overcomes the spring force, resulting limit is eliminated, the gap B between the rounded convex surface 22 and the lower part of the curved concave surface 32. When shifting friction element 10 to the left in Fig. 3 and 6, the radial component of the force generated by the spring 40 keeps the surface 22 in contact with the top surface 32. At the same time, the curved surface 20 CLASS="ptx2">Thus, at power disc brakes, when the vehicle moves in the reverse direction (reverse), the friction element 10 moves in an arc when it is cleaned surfaces 32 and 22, as they are held in constant contact with each other under the action of the radial component of the force generated by the spring 40. Therefore, any accumulation of dirt on the surfaces 32 and 22, as well as on the surfaces 20 and 30, and any corrosion of these surfaces arising from long-term Parking of the vehicle, quickly removed when moving these surfaces relative to each other each time, when the disk brake is applied during reverse travel of the vehicle.Naturally, the invention is not limited to the above examples of its implementation and it can be made many changes that will be obvious to a person skilled in the art.The invention can be used in any other type disc brake, in particular in the disk brake with a fixed yoke, in which the control means is connected to the element providing the resistance torque and directly affect each t the pads and caliper can be changed to the opposite, i.e., the concave surface can be performed on the brake pads, and convex on the caliper. Similarly, one end of each friction element may have a convex surface that interacts with the concave surface of the caliper, and the other end is a concave surface that interacts with the convex surface of the caliper. Front and rear concave and convex surfaces of the friction elements and caliper may have different radii of curvature. 1.
