Background technique
It is important component part in the motor vehicle braking system that arm is adjusted in brake, in order to improve its performance, and easy-to-operat, people have carried out long-term exploration, have proposed various embodiments.For example, Chinese patent literature discloses a kind of aerodynamic brake gap and has adjusted arm (application number: 95229939.9) have housing automatically, be equipped with in the housing worm gear that matches, worm screw and with the worm shaft of worm screw stationary fit, it is characterized in that also being equipped with on the housing by adjusting driving gear, adjust idle wheel, with the coaxial spiral gear of idle wheel, the clutch driving mechanism of mechanical engagement successively, the adjustment driving gear of this mechanism is coaxial with worm gear in housing, and the unidirectional stationary fit of the clutch of this mechanism and worm shaft, position limit pin place in the restraining groove of adjusting on the driving gear.This technology can be adjusted braking gap automatically in brake, be applicable to that various air brake vehicles use.
The brake of generally adopting is at present adjusted arm after assembling is finished, in case the stuck situation of worm and gear takes place, because it is difficult to detachably, can only take means of destruction to damage housing, causes entire product to be scrapped.Increase user cost so undoubtedly, can't reuse, caused great waste.And difficulty is also bigger in the assembling of reality and adjustment process, scraps in case assembling just causes accidentally easily, causes reject rate to increase.And its tightness is difficult to be guaranteed, and influences service behaviour.
Summary of the invention
The utility model mainly is to solve can't dismantle after the existing in prior technology assembling is finished, and can only take destructive means in case break down, and causes the part component to scrap, and increases user cost, can't reuse the technical problem of less economical grade; A kind of dismounting of being convenient to is provided, can have reused, arm is adjusted in the detachable brake that user cost is cheap.
The utility model has also solved existing in prior technology and has been difficult to assembling and debugging, and reject rate is low high, the technical problem of the not satisfactory grade of sealing; A kind of be convenient to assembling and debugging are provided, and reject rate is low, and arm is adjusted in the detachable brake of good airproof performance.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: arm is adjusted in detachable brake, comprise housing, be located at worm gear, worm mechanism in it, on housing, be provided with the adjustment axis hole, it is matched with worm screw by adjusting axle to adjust axis hole, on the adjustment axle, evenly be furnished with some shrinkage pools, the place is provided with and adjusts the perforate that axis hole connects with the corresponding housing of shrinkage pool, the steel ball that in perforate, is provided with spring and matches with shrinkage pool, it is characterized in that at described adjustment axis hole be through hole, described adjustment axle is arranged in to be adjusted in the axis hole.Adjustment axle of the present utility model is after assembling is finished, in case find that assembling occurs that deviation effects is normally used or when the stuck situation of worm and gear occurring, can will adjust axle from the lower ending opening of adjusting axis hole with instrument ejects, thereby assemble again, realized the repeated use of product, and can not produce the situation of scrapping, effectively reduce user cost.
Owing to will adjust axis hole and be made as through hole, its two ends all are easy to generate the space like this, and in order to improve sealability, as preferably, the top of described adjustment axis hole is provided with oil sealing; The bottom of described adjustment axis hole is provided with step, is provided with oil sealing down on step.
In order to improve the stability of product, increase product strength, as preferably, the bottom of described adjustment axis hole is provided with lid.The lid here also can be made as one with oil sealing, is bolt at lid for example, and some seal rings is set as oil sealing on bolt.Lid can cooperate by worm structure with the adjustment axis hole, also can adopt interference fit.
For the ease of adjusting, as preferably, described perforate for and adjust the through hole that axis hole connects, be provided with the body of bolt at its end.
Perforate here and the position relation of adjusting axis hole can have multiple mode, and as preferably, the medial axis of described perforate is vertical mutually with the medial axis of adjustment axis hole.In addition, for the ease of regular maintenance, as preferably, described housing is provided with oil hole.
Therefore, the utlity model has following characteristics: 1, reasonable in design, simple in structure, effect is obvious; 2, be convenient to assembling and adjustment, effectively improve efficiency of assembling, the rate of reducing the number of rejects and seconds; 3, in case find that assembling occurs that deviation effects is normally used or when the stuck situation of worm and gear occurring, can will adjust axle from the lower ending opening of adjusting axis hole with instrument ejects, thereby assemble again, realized the repeated use of product, and can not produce the situation of scrapping, effectively reduce user cost.
