![]() Disk-type brake
专利摘要:
The invention relates to a disk brake with a floating yoke 1, the yoke 1 of which is mounted on guide pins 11,12 seated parallel with the axis of the brake disk 2 in cut-outs of the arms 22,23 of the holder of the brake and with brake pads 25,26 arranged on both sides of the brake disk and provided with cut-outs, through which the guide pins pass. The principle of the invention resides in the fact that the guide pins are located eccentrically in elastic bushes 7, 8, 9, 10 arranged revolvingly in the yoke of the brake, and they bear with prestress against the arms of the holder of the brake. On braking, the yoke moves as the elastic bushes are deformed but with brake pad wear the pins 11, 12 move in the cut-outs of the holder arms 22, 23 to take up the wear. <IMAGE> 公开号:SU1439318A1 申请号:SU847773671 申请日:1984-11-30 公开日:1988-11-23 发明作者:Зденек Коутны;Ярослав Коваржик;Павел Крейчирж;Иржи Кубрихт 申请人:Устав Про Вызкум Моторовых Возидел (Инопредприятие); IPC主号:
专利说明:
elastic shoulders rigidly connected to the guide rods (C) 11 and 12 The heads of the guides C 11 and 12 form end stops. C 11 and 12 are prevented from being extended by pins 18 laid in the grooves 20 of the bearing heads 6. C 11 and 12 are located in the bearing V-shaped grooves 21 of the projections 22 of the brake bracket 24. Brake pads (k) 25, 26B, in the tangential direction, are supported by external butt surfaces 27 directly on the projections 22. In the radial they are fixed in two directions by mounting grooves 2-8 covering C 11 and 12. During braking, K 26 is pressed by means of a piston to the disk 2 of the brake, and K 25 by the reactive action of the bracket 1 is pressed against the disk 2 with its other side. This action is caused by the compression of the elastic shoulders of the sleeves 10. At the same time, C 11, .12 remain stationary and move only in case of increased wear of K 25, 26, compensating it. 3 з.п, ф-л, 2 Il. one FIELD OF THE INVENTION The invention relates to mechanical engineering and relates to a disc brake with a floating caliper. A brake is known, the bracket of which is mounted on guide rods x arranged parallel to the axis of the brake disc in the pairs of projections of the brake bracket, and the brake pads are located on both sides of the brake disc and are made with grooves in which guide rods are located 2845.275, CLE16D55/224, 1980). For a given disk brake, the circumferential braking force, or part of it, is transferred by means of guide rods, the dimensions of which must therefore be increased, and the movement of the guide rods worsens if the movement of the brake caliper is to be increased. The closest to the invention according to the technical nature is a disc brake with a floating bracket (for Germany No. 2804977, CL F 16 D 55/224, 1979). With a known disc brake, when transferring the braking force to the convex bearing surfaces of the projections of the bracket bracket, it is necessary to increase the movement of the brake pedal, which is a disadvantage, since in addition to the brake bracket moving, it also turns. Another disadvantage of the known disc brakes is their poor loosening after slackening. And in the case when elastic 0-shaped rings are used between the brake caliper loops and the ends of the guide rods when the gap between these parts is clogged, the required loosening does not occur. A disadvantage of the known construction is also the relatively complex process of replacing the brake pads. In order to be able to remove the plate with the invoice in the radial direction, it is necessary. fold back the bracket, and for this, you only need to unlock and push at least one guide rod, the movement of which during the radial prestressing in the landing of the guide pins is a rather complicated operation. The purpose of the invention is to increase the reliability of the brake after release and simplify the replacement of the brake lining. The essence of the proposed floating-point disc brake is that the guide rods are located eccentrically in elastic sleeves rotatably disposed in the brake bracket heads, and which with a pre-tension lie on the supporting walls of the grooves of the projections of the brake bracket, and the groove length is larger than the diameter guide rod. The projections of the brake bracket are located with contact with the outer surface of the brake pad, with the grooves of the bracket and colo The dock is located on the contacting surfaces of the projections of the bracket and the pads, and the guide rods are installed with contact with the walls of the indicated manholes. At least one of the elastic sleeves, located on the drive side, is made with elastic shoulders located between the end surfaces and end stops made on the guide rods. The guide rods on the opposite side of the drive are provided with inserted pins, the axes of which are perpendicular to the axis of the guide rods, and which are located in grooves made on the end surfaces of the brake caliper heads. 1 shows a disc brake with a floating bracket, a partial section parallel to the plane of the disk; figure 2 is the same, partial view from the side opposite to the drive. The brake bracket 1, a radially wrapping disc 2 of the brake, is made with carrier heads 3-6, in which eccentric cylindrical sleeves 7-10 are rigidly connected (for example by vulcanization) with guide rods 11 and 12. Elastic sleeves 8 and 9 with The drive side of the brake is provided with elastic shoulders 13 and 14, which rest on the end stops rigidly connected to the guide rods 11 and 12. In this case, the end stops are formed by heads 15 and 16 of the guide rods 11 and 12. From the extension, the guide rods 11 and 12 fuses Ana pins 17 and 18, laid in the slots 19 and 20 of the desulling heads 3 and 6 of the brake caliper 1, the rods 11 and 12 are guided in the bearing grooves 21 of the projections, 22 and 23 of the brake bracket 24. Bearing grooves 21 are made mainly angular in the shape of a letter V. Brake pads 25 and 26 in the tangential direction are supported by external joints, while the guide rods 11 and 12 of the bearing grooves 21 of the protrusions 22 and 23 of the brake holder 24 remain at rest, since ek-, centering holes of the elastic sleeves 7 - 10 in the bearing heads 3-6. it is determined so that the guide rods 11 and 12 are pressed against the walls of the grooves 21 and are thus prevented from displacement by a certain force. During braking, the resilient 25 shoulders 13 and 14 are again spring-loaded and the brake caliper 1 is pressed to the original braked position. Only when there is a lot of wear on the brake pads 25 and 26, when the required movement of the brake caliper 1 is greater than the compression of the elastic shoulders 13 and 14 allows, the movement of the 1X bars 1X and 11 and 12 in the bearing grooves 21 of the projections 22 and 23 of the bracket 24 occurs. brakes. However, after releasing, no reverse movement of the brake caliper 1 is caused only by the spring loading of the elastic shoulders 13 and 14, after which only a small gap arises, which is necessary for releasing the brake disk 2. Thus, the device automatically sets the required clearance between the brake pads 25 and 26 and the brake disc 2. thirty 35 40 45 During the braking, the circumferential forces act on the pads 25 and 26 with the brake butt surfaces 27 in the projections 22 and 23 of the brake bracket 24, and for this reason the load surfaces 27 do not appear directly on the brake bracket 1 or on the projections 22 and 23 brackets 24 brakes. In the radial direction, in two directions, they are fixed by adjusting grooves 28, covering guide rods 11 and 12. The brake is controlled by a piston 29 actuator sealed by a ring 30. 0 n five DISK brake works as follows. When braking, the piston 29 presses the pad 36 with the brake pad to the brake disc 2, with the reactive action, the brake caliper 1 moves in the opposite direction of movement of the piston 9 and presses the pad 25 with the brake pad from the other side to the disc 2 of the brake. This movement of the brake caliper 1 is caused by the compression of the elastic shoulders 13 and 14 of the elastic sleeves 8 and 9, while the guide rods 11 and 12 remain in the resting state in the carrier grooves 21 of the projections 22 and 23 of the brake carrier 24, since the eccentricity of the openings of the elastic sleeves 7-10 in the carrier heads 3-6. it is determined so that the guide rods 11 and 12 are pressed against the walls of the grooves 21 and are thus prevented from displacement by a certain force. During braking, the elastic 5 shoulders 13 and 14 are again spring-loaded and the brake bracket 1 is pressed to its original braked position. Only when there is a lot of wear on the brake pads 25 and 26, when the required movement of the brake caliper 1 is greater than the compression of the elastic shoulders 13 and 14 allows, the movement of the 1X bars 1X and 11 and 12 in the bearing grooves 21 of the projections 22 and 23 of the bracket 24 occurs. brakes. However, after releasing, the reverse movement of the brake caliper 1 is caused only by the spring loading of the elastic shoulders 13 and 14, after which there is only a small gap necessary to release the brake disk 2. Thus, the device automatically sets the required clearance between the brake pads 25 and 26 and the brake disc 2. 0 five 0 45 The circumferential forces act during braking on the pads 25 and 26 with brake butt surfaces 27 in the projections 22 and 23 of the brake bracket 24, and for this reason no load occurs 55 equal rods 11 and 12, so their dimensions can only be slightly increased. The bearing grooves 21 in the projections 22 and 23 of the brake bracket 24 with the guide rods 11 and 12 are in contact with the elastic force in a straight direction and thus provide movement and Significantly scored both contiguous elements. According to the invention, the replacement of the coronary pads of the pads 25 and 26 is very easy and fast. The guide rods 11 and 12 are pressed in towards the elastic shoulders 13 and 14 and rotated 180 s while the pins 17 and 18 are pulled out of the grooves 19 and 20 and when rotated 180. They move away from the notches of the grooves 21 and then the brake bracket 1 with guide rods 11 and 12 and the shoes 25 and 26 with brake linings can be pulled out of the brake bracket 24 in the radial direction. In this state, when turning, the pads 25 and 26 with brake linings are released, after which they are removed and replaced with new ones. The brake calipers are assembled in a similar way. A slight rotation of the elastic sleeves 7 10 in the carrier heads 3-6 can be achieved by applying a layer of suitable material between the resin and the metal. Easy and quick disassembly and assembly is important not only for replacing the pads 5, but also in monitoring the state of the brake and replacing the sealing and counterparts. The large volume of elastic sleeves 7-10 and elastic shoulders 13 and 14 and the favorable and yielding way of their loading due to vulcanization on guide rods 11 and 12 provide greater ability to acclimate the work of deformation and, thus, the instability of the spring effect when changing properties of the resins. The method of supporting the pads -25 and 26 with brake pads on the projections 22 and 23 of the bracket 24 outside the disc brake circumference due to the fact that the bearing grooves 21 are circumferentially open towards the center of the brake, also ensures maximum use of the surface for brake pads J and pads at the same time, they can have a simple, technologically easy-to-form form.
