Abstract
The utility model discloses a brake adjusting arm, which comprises an adjusting arm shell, an adjusting shaft hole, a worm and gear and a worm shaft which are used for driving the adjusting shaft hole, and a locking device of the worm shaft, wherein the locking device comprises a locking hoodle of a locking worm shaft, a squeezing hoodle and a locking screw matched with the hoodle, as an improvement, the locking screw is vertically arranged in a screw hole arranged on the adjusting arm shell relative to the worm shaft, and a rigid squeezing hoodle and a pillar of the locking worm shaft are arranged on the locking screw; and at least one groove matched with the hoodle is arranged at a corresponding part of the worm shaft. The locking screw vertical to the worm shaft is arranged, the rigid squeezing hoodle and the pillar of the groove on the worm shaft are arranged on the locking screw, and the pillar rigidly squeezes the hoodle, so that the hoodle tightly locks and locks up the worm, and thus the adjusting shaft is prevented from being loosened, and the braking effect is ensured.
Description
Technical field
The utility model relates to a kind of brake and adjusts arm.
Background technique
Automobile is along with use, and the gap between brake drum and the friction plate is along with wearing and tearing are increasing, and the transition point that surpasses brake when the gap of wearing and tearing will brake failure, needs to adjust arm by brake and adjusts gap between brake drum and the friction plate.Namely drive turbine drives by rotary worm and adjust axis hole, adjust the axial adjustment gap by adjusting the axis hole drive again, adjust the back by the extruding hoodle on the taper guide head extruding worm screw of lock bolt front end, push hoodle extruding locking hoodle locking worm screw.Use for a long time, may cause the extruding hoodle loosening, cause locking hoodle and can not lock worm screw fully, may make the adjustment axle loosening, increase the gap between brake drum and the friction plate, make brake failure.
Summary of the invention
The utility model is that lock was not tight after the solution prior art in use existed the worm shaft adjustment, and the gap produces the phenomenon of displacement, provides a kind of and can definitely lock locked dual fail-safe brake adjustment arm.
The technological scheme that the utility model solves existing issue is: arm is adjusted in a kind of brake, comprise the adjustment arm housing, adjust axis hole, drive worm and gear and the worm shaft of adjusting axis hole, the locking device of worm shaft, described locking device comprises the locking hoodle of locking worm shaft, the locking screw that the extruding hoodle cooperates with hoodle, as improvement, described locking screw is vertically installed in respect to worm shaft and adjusts in the screw set on the arm housing, described locking screw is provided with the pillar of rigidity extruding hoodle locking worm shaft, described worm shaft corresponding position be provided with the groove that cooperates with hoodle at least one.
As further improvement, described adjustment arm housing is provided with the protruding handle of protrusion, and described locking screw is arranged in the set screw in protruding handle one side corresponding position.
As further improvement, described locking screw end is provided with nut, and described nut is provided with spring washer.
As further improvement, also be provided with extrusion spring between described locking screw and the hoodle, described extrusion spring is coaxial with pillar, and described extrusion spring free length is greater than a column length.
The utility model compared with prior art, its beneficial effect is that a locking screw perpendicular to worm shaft is set, locking screw is provided with the pillar of set groove on rigidity extruding hoodle and the worm shaft, pillar rigidity extruding hoodle, force hoodle to lock locked worm screw, it is loosening to prevent adjusting axle, guarantees that brake effectively.
Description of drawings
Fig. 1 structural representation of the present utility model.
Embodiment
Referring to Fig. 1, the implementation case comprises adjusts arm housing 1, adjust axis hole 2, drive worm and gear and the worm shaft 3 of adjusting axis hole 2, the locking device of worm shaft, worm shaft 3 upper ends are provided with adjusting nut 31, locking device comprises the locking hoodle 4 of locking worm shaft 3, the locking screw 5 that extruding hoodle 4 cooperates with hoodle 4, locking screw 5 is vertically installed in respect to worm shaft 3 and adjusts in the screw 11 set on the arm housing 1, locking screw 5 is provided with the pillar 51 of rigidity extruding hoodle 4 locking worm shafts 3, worm shaft 3 corresponding positions be provided with the groove that cooperates with hoodle 4 32 at least one, be evenly equipped with a plurality of grooves 32 on the implementation case worm shaft 3.
Wherein, adjust the protruding handle 12 that arm housing 1 is provided with protrusion, locking screw 5 is arranged in the set screw 11 in protruding handle 12 1 side corresponding positions, adjusts the arm configuration compactness to keep brake.
Use for the ease of regulating, also be provided with extrusion spring 7 between locking screw 5 and the hoodle 4, extrusion spring 5 is coaxial with pillar 51, and extrusion spring 7 free lengths are greater than pillar 51 length.Locking screw 5 ends are provided with nut 52, and nut 52 is provided with spring washer 6.
When the implementation case is used, unclamp locking screw 5, make pillar 6 break away from hoodle 4, can keep extrusion spring 7 extruding hoodles 4, make groove 32 resilient engagement on hoodle 4 and the worm shaft 3, can pass through rotary worm axle 3 this moment, extruding hoodle 4 is in elasticity and worm shaft 3 resilient engagement, worm shaft 3 fine settings can be convenient to, after adjusting, locking screw 5 can be tightened, make the pillar 51 rigidity extruding hoodle 4 on the locking screw 5, hoodle 4 rigidity are entered in the set groove 32 of worm shaft 3, make it lock worm shaft 3 all the time, brake can not produce the gap.
