Abstract
The utility model provides an automatic regulator which is especially suitable for disc-type detents of medium and heavy camions. A drive shaft is composed of an outer or an inner polygon head and a shaft journal. The drive shaft penetrates through a link block and an inner ring and extends out from the lower end of the inner ring. The head of the drive shaft is pressed on the link block. The drive shaft has clearance fit with the link block and the inner ring. A unidirectional bearing supports between an outer ring and the inner ring. The outer circle of the outer ring is provided with a groove which basically and axially extends. An outer neck of a sliding sleeve is provided with splines or a polygon structure. The upper end of the sliding sleeve is radially fixed with the drive shaft, and a spring is enveloped between the cavity of the sliding sleeve and the shaft journal of the drive shaft by a pressing block. The pressing block is secondarily connected to the end of the drive shaft via a screw thread. One end of the compression spring is supported on the sliding sleeve, and the other end is supported on the pressing block. The upper end surface of the sliding sleeve and the lower surface of the inner ring form transmission meshing engagement. The automatic regulator is not only used for single-column detents, but also used for double-column detents.
Description
Technical field
The utility model relates to the automatic regulator of disk type braker.
Background technique
At present, in, extensively adopt the brake clearance automatic regulating apparatus in the heavy truck disk type braker, automatic regulating apparatus is made up of brake actuator and automatic regulator two-part, automatic regulator will be realized unidirectional rotary motion by its functional requirement, can be divided into two kinds of basic structure types: 1. utilize unidirectional spring just changeing to hold tightly counter-rotating to unclamp and realize that unidirectional delivery rotatablely moves; 2. utilize clutch to make it and unidirectional rotation to realize that unidirectional delivery rotatablely moves.Utilize the shortcoming of the mode of structure of unidirectional spring to be, automatic regulator relies on spring just changeing the power of holding tightly and transmits the rotating force distance when advancing, just changeing the power of holding tightly and oppositely need overcome spring during manual retraction, structural behaviour is not really stable, is easy to cause automatic regulator to lose efficacy.Utilize in the mode of structure of automatic regulator of clutch then to have such problem, promptly the cost of automatic regulator rises, technology is also comparatively complicated.At present, the drive mechanism of automatic regulator is: flip sleeve and cycle surface are the transmission engagement, flip sleeve is provided with the internal spline or the holder flower of external splines and lower end, flip sleeve upper end and the empty cover of driving shaft, between be provided with spring, the cylindrical of compact heap and flip sleeve engagement, compact heap is fixedlyed connected with the driving shaft end simultaneously, realizes that indirectly flip sleeve and driving shaft are radially fixing.In this structure, flip sleeve has external splines and blind hole internal spline or holder flower, and the work in-process difficulty is big, the processing cost height, and when the assembling compact heap, difficulty is also big, thereby makes complex structure, the manufacture cost height of whole automatic regulator.
Summary of the invention
In order to solve existing automatic regulator complex structure, shortcoming that manufacture cost is high, the present invention utilizes the advantage of above-mentioned automatic regulator, simplifies the structural manufacturing process of automatic regulator, proposes a kind of automatic regulator.
For this reason, the technical solution of the utility model is: a kind of automatic regulator, be particularly useful for, on the disk type braker of heavy truck, which comprises at least contiguous block, inner ring, driving shaft, outer ring, unilateral bearing, flip sleeve, spring, compact heap, driving shaft is made up of outer polygonal/inner polygon head and axle journal, and head is bigger than axle journal; Driving shaft passes contiguous block, inner ring, and stretches out from the inner ring lower end, and the driving shaft head is pressed on the contiguous block, driving shaft and contiguous block, inner ring Spielpassung; By the unilateral bearing supporting, the cylindrical of outer ring is provided with the groove that extends substantially vertically between outer ring and the inner ring; The outer neck of flip sleeve is provided with spline or polygon structure, the flip sleeve upper end is radially fixing with driving shaft, be packaged with spring by compact heap between the cavity of flip sleeve and the driving shaft axle journal, compact heap is connected on the driving shaft by screw pair, pressure spring one end bearing is on flip sleeve, and an end bearing is on compact heap; Be the transmission engagement between the upper-end surface of flip sleeve and the lower end surface of inner ring.
In the such scheme, between the head of driving shaft and contiguous block, packing ring can be provided with, supporting sleeve can be provided with between contiguous block and the outer ring, driving shaft and supporting sleeve Spielpassung.Described packing ring and supporting sleeve can be provided with simultaneously, also can select one.
In the described technological scheme, flip sleeve upper end radially fixedly mainly contains following three kinds of structures with driving shaft: cooperate radially by flat on flat hole on the flip sleeve and the driving shaft between flip sleeve upper end and the driving shaft and fix; Radially fixing between flip sleeve upper end and the driving shaft by spline pair; Radially fixing between flip sleeve upper end and the driving shaft by the polygonal interlock;
In the described technological scheme, be transmission engagement between the upper-end surface of flip sleeve and the lower end surface of inner ring and mainly contain following two kinds of structures: the upper-end surface of flip sleeve by steel ball supporting on the lower end surface of inner ring, steel ball is contained in the ball-and-socket of respective ends face, thereby realizes the transmission engagement; Be the transmission engagement by friction plate between the upper-end surface of flip sleeve and the lower end surface of inner ring.
The reasonable structural arrangement of described automatic regulator, during use, automatic regulator is fixed on the caliper body by contiguous block, in the process of each braking, when the outer ring accept that the braking maneuver lever transmission comes rotatablely move the time, flip sleeve can only export a unidirectional rotary motion realize the gap adjust automatically, simultaneously when manual rotation driving shaft, hexagonal and/or polygonal flip sleeve again can counterrotating satisfy the requirement of replacing brake bush.This automatic regulator promptly can be used for the single-column break and also can be used for the twin columns break.
Description of drawings
