Embodiment
As shown in Figure 2, a kind of brake clearance adjustable brake device, comprise support I 1, be installed in the brake slipper I 2 on support I 1, be installed in the wheel cylinder mechanism on support II 14, to be installed in wheel cylinder mechanism and the brake slipper II 3 be oppositely arranged with brake slipper I 2, be arranged between brake slipper I 2 and brake slipper II 3, and the brake disc 4 connected is contacted with brake slipper I 2, be arranged on the claw hook 5 between wheel cylinder mechanism and support I 1, claw hook 5 has fixed claw I 6 and fixed claw II 7, fixed claw I 6 is fixed on support I 1 by the axis of cone 8 and jump ring 9, wheel cylinder mechanism acts on fixed claw II 7.Have gap m between fixed claw I 6 and support I 1, gap m is not more than the greatest wear amount of brake slipper II.Fixed claw I 6 is provided with through hole I and is positioned at the periphery of through hole I and the through hole II communicated with through hole I, support I 1 is provided with the through hole III corresponding with through hole I, the little head end 10 of the axis of cone is fixed on support I 1 through through hole I and through hole III by nut 12 successively, the stub end 11 of the axis of cone is fixed on fixed claw I by nut 12, and jump ring 9 is arranged in through hole II and interacts with the axis of cone 8.Wheel cylinder mechanism comprise wheel cylinder housing 13, wheel cylinder housing 13 be fixed on support II 14, be placed in wheel cylinder housing 13 in and interactional wheel cylinder 15 and piston 16, the upper end of wheel cylinder 15 is provided with limited impression 17, and fixed claw II 7 is placed in limited impression 17.The displacement distance of fixed claw II 7 in limited impression 17 is that S, S equal the distance S of brake slipper II 3 to brake disc 4, equals the brake clearance S of braking device.Returnning spring 18 is provided with between brake slipper I 2 and brake slipper II 3.
A kind of brake clearance adjustable brake device of the invention as shown in Figure 1, when using in the early stage, wheelcylinder piston is by hydraulic drive displacement distance S to the left, drive brake slipper II 3 to left movement, brake slipper II 3 contacts with brake disc 4, now the fixed claw II 7 of claw hook 5 in the limited impression 17 of wheel cylinder 15 by the right-hand member of limited impression 17 to left end displacement distance S, limited impression 17 left side contacts with fixed claw II 7 just, because the displacement distance of fixed claw II 7 in limited impression 17 is S, brake slipper II 3 is S to the distance of brake disc 4, so claw hook 5 and the axis of cone 8 can not be caused to produce axial relative movement, brake slipper II 3 compression brake disc 4 simultaneously brake disc 4 has a small deformation to compress a brake slipper I 2, thus complete braking process, realize braking.When this braking device of Long-Time Service, brake slipper II 3 can wear and tear thinning, suppose that at this moment brake slipper II 3 wear extent is △ S, when now braking, wheelcylinder piston is moved to the left by hydraulic drive, and first the left side of limited impression 17 contacts the fixed claw II 7 of claw hook 5, and brake slipper II 3 fails to contact with brake disc 4 because wearing and tearing, wheelcylinder piston continues motion, and when promoting the relative axis of cone 8 of claw hook 5 to left movement △ S, brake slipper II 3 contacts with brake disc 4 and brakes.After having braked, because the thrust of wheelcylinder piston disappears, claw hook 5 does not remake reset movement under the effect of fixed claw I 6 and jump ring 9, namely moves right.Now, the fixed claw II 7 of claw hook 5 limits the reset completely of wheelcylinder piston, there is not the change of relative position with the limited impression 17 in wheelcylinder piston in fixed claw II 7, but wheelcylinder piston is moved to the left △ S relative to brake disc 4, equals the wear extent △ S of brake slipper II 3.So the distance between brake slipper II 3 and brake disc 4 can all the time along with the wear extent of brake slipper II 3 changes and changes, the amount of movement of claw hook 5 is exactly the wear extent of brake slipper 2, thus realizes the auto-compensation of the brake clearance of this braking device.Little head end 10 due to the axis of cone is positioned on support I 1, the stub end 11 of the axis of cone is positioned to fixed claw I 6 place, therefore fixed claw I 6 is when the little head end 10 of stub end 11 to the axis of cone by the axis of cone moves, and adds jump ring 9 and the frictional force of the axis of cone 8, limits the reset of claw hook 5 further.
