Optimize, above-mentioned vehicle brake gap automatic modulator, its augmentor comprises retainer, be fixedly installed roller in the draw-in groove of retainer, roller rolls with the inclined-plane, rear end of oblique guide pad and cooperates, and the upper end of retainer is connected with wedge shaped ejector pin, and the outer cover of wedge shaped ejector pin has return spring.
Optimize, above-mentioned vehicle brake gap automatic modulator, its oblique guide pad is fixedly connected with housing by positioning screwn.
Optimize, above-mentioned vehicle brake gap automatic modulator, the two ends of its housing are provided with dust-proof cover.
Optimize, above-mentioned vehicle brake gap automatic modulator, the upper end of its housing is provided with seal closure, and the lower end of return spring contacts cooperation with seal closure.
The utility model is converted into braking force to air chamber thrust by self-regulated device voussoir, and retardation efficiency is high, react rapider, so that little than traditional drum brake of air chamber specification, air consumption is little, the saving oil consumption; Establish two cover brake clearance automatic adjusting mechanisms in the self-regulated device, in braking return process, automatically eliminate respectively the excessive gaps between two shoes friction plates and the brake drum, remain the setting gap that car load is constant, improve braking safety; The utility model can be realized the continuous setup of the brake clearance of drum brake, makes braking process rapidly, fast, sluggishness can not occur, increases the reliability of braking and the Safety performance of vehicle.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described;
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model is a kind of vehicle brake gap automatic modulator, comprises housing 1, is provided with overrunning clutch 17 in the transverse holes of housing 1, and overrunning clutch 17 comprises oblique guide pad 3, torsion spring 4, helical worm 5 and Steel Cable Baffle Ring 13; Described oblique guide pad 3 and helical worm 5 are connected by Steel Cable Baffle Ring 13, tiltedly are provided with torsion spring 4 in the joint endoporus of guide pad 3 and helical worm 5; Be provided with push rod 6 in the interior threaded hole of described helical worm 5, push rod 6 and helical worm 5 screw-thread fit, the flexible collar 15 of the end card of push rod 6; One end of described helical worm 5 is connected with internal gear 8, and internal gear 8 is by spline and helical worm 5 Spielpassung, and an end of internal gear 8 is connected with stage clip 7, and the cone of friction 18 in the outer surface of internal gear 8 and the housing 1 cooperates and contacts; Be provided with augmentor 19 in the longitudinal hole of described housing 1.Augmentor 19 comprises retainer 10, is fixedly installed roller 9 in the draw-in groove of retainer 10, and roller 9 rolls with the inclined-plane, rear end of oblique guide pad 3 and cooperates, and the upper end of retainer 10 is connected with wedge shaped ejector pin 11, and the outer cover of wedge shaped ejector pin 11 has return spring 12.Tiltedly guide pad 3 is fixedly connected with housing 1 by positioning screwn 2.The two ends of housing 1 are provided with dust-proof cover 14.The upper end of housing 1 is provided with seal closure 16, and the lower end of return spring 12 contacts cooperation with seal closure 16.
When working principle of the present utility model is set the gap for being no more than when the gap between brake drum and the friction plate, helical worm 5 axial motions, distance of relative movement between helical worm 5, the internal gear 8 is no more than the gap between the helical spline, be that internal gear 8 is static, and do not slide between the cone of friction 18; When the gap between brake drum and the friction plate surpasses the setting gap, helical worm 5 is outwards motion (during braking) vertically, distance of relative movement between helical worm 5, the internal gear 8 has surpassed the gap between the helical spline, because the locking effect of overrunning clutch, tiltedly guide pad 3, helical worm 5 can not rotate mutually, and helical worm 5 can drive internal gear 8 overcome frictions and produce rotational slide along 18 of cones of friction; Helical worm 5 is inwards motion (during brake off) vertically, helical worm 5, distance of relative movement between the internal gear 8 has surpassed the gap between the helical spline, because the locking of overrunning clutch is removed, oblique guide pad 3, helical worm 5 can rotate mutually, the frictional force that internal gear 8 and cone of friction are 18 can overcome by the running torque drive helical worm 5 that the rotation spline produces the frictional force of overrunning clutch and rotate, because push rod 6 can not rotate, so helical worm 5, rotatablely moving between the push rod 6 can only produce and move axially, be about to push rod 6 and outwards move a certain distance, that is the brake clearance between elimination brake drum and the friction plate.
The utility model is converted into braking force to air chamber thrust by self-regulated device voussoir, and retardation efficiency is high, react rapider, so that little than traditional drum brake of air chamber specification, air consumption is little, the saving oil consumption; Establish two cover brake clearance automatic adjusting mechanisms in the self-regulated device, in braking return process, automatically eliminate respectively the excessive gaps between two shoes friction plates and the brake drum, remain the setting gap that car load is constant, improve braking safety; The utility model can be realized the continuous setup of the brake clearance of drum brake, makes braking process rapidly, fast, sluggishness can not occur, increases the reliability of braking and the Safety performance of vehicle.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement all should belong to protection domain of the present utility model.
