Abstract
The utility model provides a worm round pin adjustable brake adjustment arm belongs to the auto -parts field. Including casing, worm round pin, worm and worm wheel, worm round pin, worm and worm wheel hold in the casing, and the middle part is sold formed at the worm to worm an organic whole, and worm round pin one end is provided with the lug along its axial, and the lug diameter is less than worm round pin diameter, overlaps in proper order between worm and the lug to be equipped with adjusting nut and locking plate, and adjusting nut passes through screw -thread fit with the casing, is provided with the recess on the worm wheel, is provided with the sealing washer in the recess, and the worm wheel has still covered the apron. The utility model discloses set up worm round pin and worm integration and the setting of worm wheel sealing washer, existing effect is avoided between worm and the worm, and skidding between worm wheel and the apron prevents that the dust from getting into the clearance, reduces the malfunctioning probability of adjustment arm, is applicable to the brake adjustment arm that has different width fang xin again.
Description
Technical field
This utility model belongs to auto parts machinery field, particularly to a kind of adjustable braking adjusting-arm of worm pin.
Background technology
Braking adjusting-arm is the important component part in motor vehicle braking system, and the braking adjusting-arm of prior art is generally formed by parts assemblings such as housing, worm screw, worm pin, worm gear and linings, and the worm pin of braking adjusting-arm is usually supported on housing, and itself and worm screw coordinate.
But braking adjusting-arm Shortcomings has: 1, between existing worm pin and worm screw, there is fit clearance, it is easy to cause worm screw play, and produce noise, occur often and between worm screw to skid or abrasion in worm pin assembling and operation process, cause that adjusting arm lost efficacy；2, specific worm pin length must cooperation side's specific braking adjusting-arm of core width.
Utility model content
This utility model is in that to provide a kind of adjustable braking adjusting-arm of worm pin, has anti-sliding stop, is simultaneously suitable for the feature with the braking adjusting-arm of different in width Fang Xin.
For achieving the above object, this utility model scheme is as follows:
A kind of adjustable braking adjusting-arm of worm pin, including housing, worm pin, worm and worm wheel, described worm pin, worm and worm wheel are contained in housing, described worm screw is integrally formed in the middle part of worm pin, axially arranged there is projection described worm pin one end along it, described bump diameter is less than worm pin diameter, adjusting nut and locking plate it is arranged with successively between described worm screw and projection, described adjusting nut and housing pass through threaded engagement, described worm gear is provided with groove, being provided with sealing ring in described groove, described worm gear is also covered with cover plate.
In order to prevent worm screw and adjusting nut from skidding, thus producing abrasion, between described worm screw and adjusting nut, also it is arranged with pad.
In order to be fixed on housing by locking plate, described locking plate is fixed by bolt and housing.
Worm pin and worm screw integrated setting and worm gear seal circle are arranged by this utility model, have both been prevented effectively between worm screw and worm screw, the skidding between worm gear and cover plate, prevent again dust from entering gap, effectively reduce adjusting the probability that arm is malfunctioning；By rotating adjusting nut, worm screw is pushed the Fang Xin distance to housing wall, controlling party core and worm screw so that it is be applicable to the braking adjusting-arm with different in width Fang Xin；

Label declaration
Housing 100, worm pin 1, worm screw 2, projection 3, pad 4, adjusting nut 5, locking plate 6, bolt 7, side's core 120, worm gear 300, groove 310, sealing ring 400, cover plate 500.
Detailed description of the invention
A kind of adjustable braking adjusting-arm of worm pin (as shown in Figure 3), including housing 100, worm pin 1, worm screw 2 and worm gear 300, described worm pin 1, worm screw 2 and worm gear 300 are contained in housing 100, worm screw 2 is integrally formed in the middle part of worm pin 1, (as depicted in figs. 1 and 2) axially arranged there is projection 3 worm pin 1 one end along it, projection 3 diameter is less than worm pin 1 diameter, pad 4 it is arranged with successively between described worm screw 2 and projection 3, adjusting nut 5 and locking plate 6, (such as Fig. 3, shown in Fig. 4 and Fig. 5) adjusting nut 5 with housing 100 by threaded engagement: adjusting nut 5 arranged outside has external screw thread, corresponding, female thread (not indicating in figure) it is provided with inside housing 100.Being provided with groove 310 on described worm gear 300, be provided with sealing ring 400 in described groove 310, described worm gear is also covered with cover plate 500(as shown in Figure 6).
This utility model breaks through conventional worm 2 and worm pin 1 is equipped with integrated setting, simultaneously further with rotating adjusting nut 5, by worm screw 2 side of pushing core 120 to housing 100 wall, the distance of controlling party core 120 and worm screw 2, between worm gear 300 and cover plate 500, it is provided with sealing ring 400 simultaneously, had both been prevented effectively between worm screw and worm screw, the skidding between worm gear and cover plate, prevent dust from entering gap, effectively reduce adjusting the probability that arm is malfunctioning；It is applicable to again the braking adjusting-arm with different in width Fang Xin.
Above example is only in order to illustrate the technical solution of the utility model and unrestricted, other amendments that the technical solution of the utility model is made by those of ordinary skill in the art or equivalent replace, without departing from the spirit and scope of technical solutions of the utility model, all should be encompassed in right of the present utility model.
