Detailed Description
The following description will further describe an automatic return device of a brake pad according to the present invention with reference to the accompanying drawings.
As shown in fig. 1-4, the automatic brake pad returning device of the present embodiment includes a brake pad 1, and is characterized by further including a returning device 2; the brake pad 1 is divided into an inner pad 3 and an outer pad 4 which are symmetrical with each other; the brake pad 1 is provided with a hollow groove 5, the side edge of the brake pad 1 is also provided with a movable groove 6 penetrating through the hollow groove 5, and the movable groove 6 is also provided with a limit groove 7; the return device 2 comprises a support rod 8, a movable rod 9 and a spring 10; the support rod 8 is movably connected with the support rod 8 through a movable pin, movable rods 9 are mounted at two ends of the support rod 8, a bearing 11 is mounted on each movable rod 9, and the bearing 11 is slidably mounted in the limiting groove 7; the support rod 8 is connected with the brake pad 1 in a sliding manner through a movable rod 9 and a bearing 11; still be equipped with draw-in groove 12 on the movable rod 9, install spring 10 between movable rod 9 and the movable rod 9, spring 10 installs in draw-in groove 12.
The utility model discloses a working process: firstly, the brake pad 1 is installed on a brake disc to be used, when the brake pad is used, a person steps on an automatic pedal on a motor car to extrude the brake pad 1 to be in contact with the brake disc, the return device 2 is extruded while the brake pad 1 is extruded, so that the support rods 8 rotate by taking the intersection point of the two support rods 8 as a base point, the support rods 9 move in the limiting grooves 7 along with the rotation of the support rods 8, the springs 10 are pulled when the movable rods 9 move, the springs 10 are stretched towards two sides, the brake pad 1 and the brake disc generate friction, the speed reduction and stop effects are achieved, after the automatic pedal is released, the brake pad 1 and the return device 2 are not subjected to extrusion force, the stretched springs 10 return to the original shape due to the reset force of the springs 10, and the springs 10 drive the movable rods 9 and the support rods 8 to return, so that the brake pad 1 is driven to automatically and rapidly reset.
The utility model has the advantages that: through the arrangement of the return device 2, when the automatic pedal is loosened in the use process of the brake pad 1, the brake pad 1 is automatically returned by utilizing the resilience force of the spring 10, so that the phenomena of friction, partial friction, braking noise and the like are effectively reduced; through the arrangement of the support rods 8, the two support rods 8 are crossed and movably mounted through the pins, the support rods 8 are connected with the inner plate 3 and the outer plate 4, when the brake pad 1 is extruded, the support rods 8 can rotate with the brake pad 1 extruded and with the joint points as base points, and therefore the distance between the inner plate 3 and the outer plate 4 can be contracted due to extrusion; the movable rods 9 are arranged at the two ends of the support rod 8, the springs 10 are arranged on the movable rods 9, the movable rods 9 are driven to move towards the two sides when the support rod 8 rotates, so that the springs 10 can be stretched, the movable rods 9 and the support rod 8 are driven to return through the return force of the springs 10 when the support rod 8 returns, and the effect of quickly returning the brake pad 1 is achieved; the movable rod 9 is convenient to move by installing the bearing 11 on the movable rod 9, and the limit groove 7 is arranged on the movable groove 6, so that the bearing 11 is slidably installed in the limit groove 7, the moving position of the movable rod 9 is limited, and the displacement is avoided; the movable rod 9 is provided with the clamping grooves 12, so that two ends of the spring 10 are fixedly arranged in the clamping grooves 12, and the situation that the spring 10 cannot work normally due to the deviation of the position in the use process is avoided.
The scope of the present invention is not limited to the above embodiments and their variations. The present invention is not limited to the above embodiments, and other modifications and substitutions may be made by those skilled in the art.
