Abstract
The utility model relates to a disk brake of an automobile crane, which comprises a brake disk, friction blocks, friction block slide rails, brake calipers, branch pumps, guiding pins and an oil inlet. The disk brake is characterized in that the brake disk is mounted on a braking flange of a winch, the friction block slide rail is mounted on a support of the winch, the two friction block embedded into the friction block slide rails are positioned on two sides of the brake disk, the branch pumps are mounted in the brake calipers, then the brake calipers with the branch pumps are fixed onto the friction block slide rails by the two guiding pins, and an oil pipe from a main pump is connected onto the oil inlet. Gaps among the two friction blocks and the brake disk are adjusted by adjusting the guiding pins. The disk brake of an automobile crane has the advantages that the disk brake is low in efficacy reduction after being submerged, can regain normality after braking once or twice, is extremely small in heat expansion along the thickness direction of the brake disk, does not change the braking gaps to change braking stroke, is excellent in heat dissipation performance due to the exposed brake disk and the like.
Description
Technical field:
The utility model belongs to car hosit and makes the field, is specifically related to a kind of plate disc brake of car hosit.
Background technology:
Drg is to utilize friction that kinetic energy is converted into heat energy, resolves heat dissipation problem and can play a multiplier effect to the performance that improves drg.The drg tradition of car hosit hoisting mechanism is used external contracting drum brake more, though external contracting drum brake is with low cost, performance is not good, its shortcoming: 1. brake axle is because out-of-balance force effect and load by bending; 2. it is irregular that brake collar specific pressure skewness makes the wadding wearing and tearing; 3. thermal diffusivity is bad.Along with the development of technology, the plate disc brake of superior performance arises at the historic moment, and is used widely on car, and this drg can be used in the crane hoisting mechanism through improving.
Summary of the invention:
The purpose of this utility model be for overcome external contracting drum brake make brake axle by bending load, be difficult for the heat-dissipation shortcoming, and provide a kind of plate disc brake of car hosit.
The technical solution adopted in the utility model is: a kind of plate disc brake of car hosit, comprise: brake disc, friction shoe, friction shoe slide rail, braking clamp body, wheel cylinder, guide finger, oil inlet, it is characterized in that brake disc is contained on the hoist braking flange, the friction shoe slide rail is contained on the hoist bearing, two friction shoes are embedded in the friction shoe slide rail, and be positioned at the both sides of brake disc, wheel cylinder is packed in the braking clamp body, the braking clamp body that wheel cylinder will be housed then is fixed on the friction shoe slide rail by two guide fingers, connects the oil pipe from master cylinder on oil inlet.Adjust the gap of two friction shoes and brake disc by adjusting guide finger.
After the utlity model has immersion, usefulness reduces few, and only needs can recover normal through twice braking; Brake disc is minimum along the thermal expansion amount of thickness direction, can not change brake clearance and braking distance is changed; Brake disc exposes, and heat dispersion is good.
Description of drawings:
Accompanying drawing is the utility model structural representation.
Among the figure: 1. brake disc, 2. friction shoe, 3. friction shoe slide rail, 4. braking clamp body, 5. wheel cylinder, 6. guide finger, 7. oil inlet, 8. winding drum, 9. hoist bearing, 10. hoist braking flange.
The specific embodiment:
As shown in drawings, a kind of plate disc brake of car hosit comprises: brake disc 1, friction shoe 2, friction shoe slide rail 3, braking clamp body 4, wheel cylinder 5, guide finger 6, oil inlet 7.
Glancing impact not, friction shoe 2 separates with brake disc 1, and brake disc 1 can freely rotate; Glancing impact, high-pressure and hydraulic oil from master cylinder enters brake cylinder 5, the piston of wheel cylinder 5 is pushing away left side friction shoe 2 and is moving to brake disc 1, when left side friction shoe 2 was pressed onto on the brake disc 1, wheel cylinder 5 worked on, and this moment, braking clamp body 4 began to be moved to the left on guide finger 6, the friction shoe 2 that braking clamp body 4 hooks the right side is moved to the left presses to brake disc 1, the friction shoe 2 of the left and right sides can firmly stick brake disc 1, and brake disc 1 is stopped operating, and reaches the braking purpose.
