Abstract
The utility model discloses a pneumatic disk brake which comprises a brake disk, a brake strip, a spiral propeller and a driving mechanism. The spiral propeller comprises a spiral propeller with a spiral groove and a propeller rotary plate, and the propeller rotary plate is connected with the driving mechanism. The propeller rotary plate is provided with a gear wheel nut and a screw push bar interlocked with the propeller rotary plate, and the screw push bar is connected with the brake strip. A brake interstice automatic regulating mechanism composed of a one way traction clutch, a friction disk clutch and a regulating sleeve is arranged between the propeller rotary plate and the gear wheel nut. The beneficial technique effects of the pneumatic disk brake are that the brake is provided with an interstice automatic regulating mechanism. When the braking member generates friction, the pneumatic disk brake can automatically regulate the interstice, and the brake can keep a preset normal interstice. The pneumatic disk brake has the advantages of stable brake performance, good safety performance and non-braking deviation phenomenon.
Description
Technical field:
The utility model relates to a kind of break, relates in particular to a kind of automobile air-pressure disc brake.
Background technique:
Automobile mainly contains drum brake and air-pressure disc brake with break at present, the air-pressure disc brake of prior art is mainly by brake disc, braking frictional plate, main, secondary caliper, formation such as spiral propeller and driving mechanism, driving mechanism not only rotates but also move axially spiral propeller, and brake strip and brake disc are compressed by spiral handspike, produce braking moment, after brake strip and brake disc friction gap increase, because of there not being the brake clearance automatic adjusting mechanism, braking ability can descend thereupon, also the break deviation phenomenon can occur, have a strong impact on traffic safety.As improvement, at application number is 91106275,0, publication number is CN1072001A, the application for a patent for invention that name is called " disk type braker " discloses a kind of air-pressure disc brake that has the brake clearance regulating mechanism, but this regulating mechanism and non-automatic adjustment, need manually regularly adjust, and comparatively bother, its travel safety can not guarantee sometimes.
Summary of the invention:
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art exactly, and a kind of air-pressure disc brake that can adjust brake clearance automatically is provided.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: air-pressure disc brake, comprise brake disc, brake strip, spiral propeller, driving mechanism, spiral propeller comprises and has spiral fluted spiral propeller seat and advance rotating disk, advance rotating disk and driving mechanism interlock, the gear nut and the spiral of interlock push away pavilion to advance rotating disk to be provided with it, spiral pushes away pavilion and is connected with brake strip again, is provided with by one-way drive clutch between propelling rotating disk and gear nut, friction disk clutch, adjust the automatic controlling mechanism of brake clearance that cover constitutes.
Useful technique effect of the present utility model is: because break is provided with the mechanism in automatic adjusting gap, when friction takes place at brake component in the utility model, can regulate the gap automatically, all the time make break keep the normal clearance that configures in advance, thereby it is stable to have a braking ability, be difficult for producing deviation phenomenon, the advantage that Safety performance is good.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view (part) of Fig. 1;
Fig. 3 is the partial enlarged drawing of the clearance self-regulating mechanism of Fig. 1.
Embodiment:
Below in conjunction with accompanying drawing and specific embodiment the utility model is further described:
As shown in the figure, air-pressure disc brake, comprise brake disc 2, brake strip 8, spiral propeller 11, driving mechanism 4, spiral propeller 11 comprises and has spiral fluted spiral propeller seat 10 and advance rotating disk 9, advance rotating disk 9 and driving mechanism 4 interlocks, advance rotating disk 9 to be provided with the gear nut 14 and the spiral handspike 12 of interlock with it, spiral handspike 12 is connected with brake strip 8 again, is provided with by one-way drive clutch 15 between propelling rotating disk 9 and gear nut 14, friction disk clutch 16, adjust the automatic controlling mechanism of brake clearance that cover 17 constitutes.Described driving mechanism 4 comprises brake chamber 1, brake arm 3, and brake chamber 1 is hinged with an end of brake arm 3 by piston rod 5, and the other end of brake arm 3 is fixedlyed connected with advancing rotating disk 9.
When automobile brake, brake chamber 1 promotes brake arm 3 and rotates, and then makes spiral propeller 11 produce motion, adjusts cover 17 by one-way drive clutch 15 drives and rotates.When brake clearance during greater than setting value, adjusting cover 17 friction plates of stirring friction disk clutch 16 rotates gear nut 14, and then make with it the spiral handspike that can not rotate 12 translations of assembling, promoting brake strip 8 compresses with brake disc 2, produce braking moment, when braking moment arrived a certain numerical value greatly, clutch 16 skidded, and spiral handspike 12 stops to move.
During brake off, have the brake clearance setting structure, after spiral handspike 12 returns, just can guarantee that break returns to the setting gap again, has just finished the automatic adjustment of brake clearance in a braking process by adjusting on the cover 17.
Claims (2)
1, air-pressure disc brake, comprise brake disc, brake strip, spiral propeller, driving mechanism, spiral propeller comprises and has spiral fluted spiral propeller seat and advance rotating disk, advance rotating disk and driving mechanism interlock, advance rotating disk to be provided with the gear nut and the spiral handspike of interlock with it, spiral handspike is connected with brake strip again, it is characterized in that: be provided with the automatic controlling mechanism of brake clearance that is made of one-way drive clutch, friction disk clutch, adjustment cover between propelling rotating disk and gear nut.
2, air-pressure disc brake according to claim 1 is characterized in that: described driving mechanism comprises brake chamber, brake arm, and brake chamber is hinged by an end of piston rod and brake arm, and the other end of brake arm is fixedlyed connected with advancing rotating disk.
