Abstract
The invention provides a self-adjusting mechanism of the disc brake clearance of a heavy truck. The self-adjusting mechanism of the disc brake clearance of the heavy truck comprises a fork shaft, an intermediate gear, a one-way clutch, an overload clutch shaft, a spring, an overload clutch, and overload clutch shell, thrust collars with a bevel and pistons; the fork shaft is connected with the clutch shell, into which the overload clutch is arranged through the overload clutch shaft, the intermediate gear is installed on the fork shaft, the one-way clutch is arranged between the overload shaft and the intermediate gear, two thrust collars with a bevel are arranged at both sides of the intermediate gear, and the intermediate gear is partially engaged with the bevels of the two thrust collars, each thrust color with a bevel is sleeved with a piston, and a spring is arranged between the overload clutch and the thrust collars with a bevel. The invention has the advantages of simple processing, convenient assembly, high efficiency and long service life.
Description
Technical field
The present invention relates to be used for the clearance self-regulating mechanism of heavy-duty car disk brake, belong to the disk brake clearance self-regulating mechanism technical field.
Background technique
The disk type braker that is used for heavy-duty car is exactly the automatic adjustment that disk type braker is convenient to realize brake clearance than one of considerable advantage of drum brake, and the structure of clearance self-regulating mechanism and performance are the important indicators of the various disk type braker qualities of contrast.The clearance self-regulating mechanism great majority that are used for heavy-duty car disk brake at present are chain transmissions, and adjusting efficient is low, and homophony and the complex structure from transferring exist deficiencies such as difficulty of processing is big, assembly technology is complicated, working life is low.
Summary of the invention
The present invention is directed to the deficiency that the clearance self-regulating mechanism of existing disk type braker exists, provide a kind of process simple, easy to assembly, efficient is high, the heavy car disk brake clearance self-regulating mechanism of high life.
The present invention adopts following technical solution:
Heavy car disk brake clearance self-regulating mechanism, comprise declutch shift shaft, intermediate gear, overrunning clutch, the overload clutch axle, spring, overload clutch, the overload clutch shell, the push-plate and the piston of band umbrella shape tooth, declutch shift shaft is connected on the overload clutch shell, overload clutch is installed in the overload clutch shell by the overload clutch axle, intermediate gear is installed on the declutch shift shaft, between overload clutch axle and the intermediate gear overrunning clutch is housed, the intermediate gear both sides are equipped with the push-plate of two band umbrella shape teeth, the umbrella shape toothed portion of the push-plate of intermediate gear and two band umbrella shape teeth all meshes, all be set with piston on the push-plate of each band umbrella shape tooth, between the push-plate of overload clutch and band umbrella shape tooth spring be installed.
Spring is in compressive state after initial assembling, the size of this pressure has determined the slipping torque of overload clutch, when declutch shift shaft begins to rotate, driving force passes to overload clutch by the overload clutch shell, driving force is transferred to the overload clutch axle then, the effect of overrunning clutch is that the gap that has guaranteed to compensate is not reduced, that is to say, supposing to turn clockwise to compensate brake clearance, and when turning clockwise so, overrunning clutch is a carry-over moment, and when being rotated counterclockwise, overrunning clutch will skid, and the overload clutch axle can the cycle initial position, and intermediate gear keeps original position motionless.Intermediate gear passes to the push-plate and the piston of both sides band umbrella shape tooth, the moment of rotation of final input be converted into piston extending amount, thereby realize the compensation in gap.
That the present invention processes is simple, easy to assembly, efficient is high, high life.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
Among the figure: 1, declutch shift shaft, 2, intermediate gear, 3, overrunning clutch, 4, the overload clutch axle, 5, spring, 6, overload clutch, 7, the overload clutch shell, 8, the push-plate of band umbrella shape tooth, 9, piston.
Embodiment
As shown in drawings, heavy car disk brake clearance self-regulating mechanism of the present invention mainly comprises the push-plate 8 and the piston 9 of declutch shift shaft 1, intermediate gear 2, overrunning clutch 3, overload clutch axle 4, spring 5, overload clutch 6, overload clutch shell 7, band umbrella shape tooth.Declutch shift shaft 1 and 7 riveted joints of overload clutch shell.Overload clutch 6 is installed in the overload clutch shell 7 by overload clutch axle 4.Intermediate gear 2 is installed on the declutch shift shaft 1, between intermediate gear 2 and the overload clutch axle 4 overrunning clutch 3 is housed, the effect of overrunning clutch 3 is that the gap that has guaranteed to compensate is not reduced, and that is to say that supposing to turn clockwise to compensate brake clearance, when turning clockwise so, overrunning clutch is a carry-over moment, and when being rotated counterclockwise, overrunning clutch will skid, overload clutch axle 4 can the cycle initial position, and intermediate gear 2 keeps original positions motionless.Intermediate gear 2 both sides are equipped with the push-plates 8 of two band umbrella shape teeth, and all mesh with the umbrella shape toothed portion of the push-plate 8 of two band umbrella shape teeth, all are set with piston 9 on the push-plate 8 of each band umbrella shape tooth.Between the push-plate of overload clutch and band umbrella shape tooth spring 5 is installed.
Claims (1)
1, a kind of heavy car disk brake clearance self-regulating mechanism, comprise declutch shift shaft, intermediate gear, overrunning clutch, the overload clutch axle, spring, overload clutch, the overload clutch shell, the push-plate and the piston of band umbrella shape tooth, it is characterized in that: declutch shift shaft is connected on the overload clutch shell, overload clutch is installed in the overload clutch shell by the overload clutch axle, intermediate gear is installed on the declutch shift shaft, between overload clutch axle and the intermediate gear overrunning clutch is housed, the intermediate gear both sides are equipped with the push-plate of two band umbrella shape teeth, the umbrella shape toothed portion of the push-plate of intermediate gear and two band umbrella shape teeth all meshes, all be set with piston on the push-plate of each band umbrella shape tooth, between the push-plate of overload clutch and band umbrella shape tooth spring be installed.
