Abstract
The utility model discloses an adjusting mechanism of a brake adjusting arm. The adjusting mechanism comprises an adjusting arm shell, an adjusting axial hole, a worm and gear driving the adjusting axial hole, a worm shaft and a seal ring. An adjusting nut and a locking device for a worm are arranged at the upper end of the worm shaft, a gear ring is arranged on the outer portion, in the shell, of the worm shaft, the locking device comprises locking balls used for locking the worm, a squeezing ball and a locking bolt matched with the balls, the squeezing ball is arranged on the squeezing spring, the lower end face of the locking bolt is provided with a spherical groove matched with the squeezing ball, and the side face of the locking bolt is provided with arc steps matched with the locking balls. By means of the structure, the stress of the locking bolt is small when the balls are squeezed, the spring force is increased, the service life of a spring is prolonged, and product quality is improved.
Description
Technical field
The utility model relates to vehicle body fittings technical field, relates in particular to a kind of regulating mechanism of braking adjusting arm.
Background technique
The braking of vehicle generally all utilizes the contact friction function between brake shoe and brake drum to realize.In the process of driving, meeting contact friction continually between brake shoe and brake drum, makes gap between the two become large, and this can affect the Security of car brakeing mechanism work.So all can be provided with adjustment arm in the arrestment mechanism of vehicle, in order to adjust the brake clearance between brake shoe and brake drum, make brake clearance between the two can keep a steady state value, to guarantee the Security of car brakeing mechanism work.
The regulating mechanism of adjusting at present arm comprises nut, locking screw, locking hoodle, extruding hoodle and extrusion spring, owing to there is certain gap in the front-end face extruding hoodle of locking screw, and push stressed larger, cause spring force to reduce, reduce the working life of extrusion spring, increased the cost of production of whole adjustment arm simultaneously.
In view of this, the inventor, for the above-mentioned defect further investigation of braking adjusting arm in prior art, has this case to produce then.
Summary of the invention
In order to overcome above shortcomings part in prior art, the purpose of this utility model is to provide a kind of regulating mechanism of braking adjusting arm, and it can improve working life, reduces production costs.
In order to reach above-mentioned object, the utility model adopts following concrete technological scheme: the regulating mechanism of braking adjusting arm, comprise adjustment arm housing, adjust axis hole, drive the worm and gear of adjusting axis hole, worm shaft and seal ring, worm shaft upper end is provided with the locking device of adjusting nut and worm screw, worm shaft is positioned at housing outward and is provided with gear ring, described locking device comprises the locking hoodle of locking worm screw, extruding hoodle and the lock bolt coordinating with hoodle, extruding hoodle is located on extrusion spring, the lower end surface of described lock bolt is provided with and the rounded channels of pushing hoodle and matching, its side is provided with and the circular arc stage of locking hoodle and matching.
The utility model advantage is compared with prior art: owing to being provided with above structure, the utility model lock bolt is stressed little in extruding hoodle, increases spring force, extends the working life of spring, improves the quality of product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment
In order further to explain the technical solution of the utility model, below by specific embodiment, the utility model is elaborated.
Embodiment 1:
Shown in Fig. 1, the regulating mechanism of braking adjusting arm, comprise and adjust arm housing 1, adjust axis hole 2, drive the worm and gear of adjusting axis hole, worm shaft 3 and seal ring 4, worm shaft 3 upper ends are provided with the locking device of adjusting nut 5 and worm screw, outside worm shaft 3, be positioned at housing and be provided with gear ring 6, described locking device comprises the locking hoodle 7 of locking worm screw, extruding hoodle 8 and the lock bolt 9 coordinating with hoodle, extruding hoodle 8 is located on extrusion spring 12, the lower end surface of described lock bolt 9 is provided with and the rounded channels 10 of pushing hoodle 8 and matching, its side is provided with and the circular arc stage 11 of locking hoodle 7 and matching, lock bolt is stressed little in extruding hoodle, increase spring force, extend the working life of spring, improve the quality of product.
But above-mentioned embodiment is exemplary, be to be this patent to be comprised to the restriction of scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses do be anyly equal to change or modify, all fall into the scope that this patent comprises.
