Abstract
The utility model provides a kind of break with mechanical parking braking.It comprises sealed gas chamber, brake slipper, load steel backing, the return spring of brake slipper and load steel backing, it is provided with cylinder, cylinder piston, opposite side at cylinder piston is provided with and the interactional spring of cylinder piston, it also is provided with by the lever of cylinder piston effect, during parking braking, lever drives brake slipper and the motion of load steel backing.The utility model can combine setting with the air sac type Service Brake, simplifies structure, installation and easy to operate.
Description
Technical field
The utility model relates to the break field of motor vehicle such as automobile, relates in particular to the break with mechanical parking braking.
Background technique
Present air sac type break, by inflation to sealed gas chamber, make brake slipper by on hold out against to connect airtight and touch brake drum, and realize braking, during brake off, by to the sealed gas chamber exhaust, under the effect of return spring, brake slipper resets.This break, prevent advantages such as brake locking although have flexible braking, have the shortcoming that does not have in conjunction with being provided with parking braking, function is unsound, even other parking braking is set, but make huge bulky complex of whole braking system and troublesome poeration inevitably.
Summary of the invention
Technical problem to be solved in the utility model provides break a kind of and the band machinery parking braking that Service Brake combines.For this reason, the utility model is by the following technical solutions: it comprises sealed gas chamber, brake slipper, load steel backing, the return spring of brake slipper and load steel backing, it is provided with cylinder, cylinder piston, opposite side at cylinder piston is provided with and the interactional spring of cylinder piston, it also is provided with by the lever of cylinder piston effect, during parking braking, lever drives brake slipper and the motion of load steel backing, lever drives brake slipper and the motion of load steel backing can be by being provided with the parking braking top board that acts on steel backing on the lever.The steel backing width is greater than brake slipper, and steel backing extends abutting end with the parking braking top board to both sides.The utility model is provided with the supporting frame with supporting baffle in the annular, be provided with annular air-pocket diaphragm, thermal insulating pad that the cross section is ∑ shape on the interior supporting baffle successively, load steel backing and brake slipper are located on the thermal insulating pad successively, brake slipper along the circumferential direction, be the polylith shape, have the supporting pin that is connected on the supporting frame between the brake slipper, return spring is between supporting pin and the steel backing, brake slipper is provided with radiating groove, and interior supporting baffle is provided with radiation hole outside sealed gas chamber.Because adopt above technological scheme, the utility model can combine setting with the air sac type Service Brake, simplifies structure, installation and easy to operate, the structure of parking braking does not influence the structure of sealed gas chamber, and braking is more reliable, during braking, the effect of reinforcement is arranged.
The utility model can adopt following further technological scheme simultaneously:
The utility model also can be provided with and act on separating of lever and stay shift fork, and acts on separating of shift fork and stay helix bar.Like this, can manually remove, play the effect of insurance with the braking function that the utility model is provided parking braking.
The utility model can be provided with radiation hole and heat radiation fan blade.

Embodiment
The utility model comprises sealed gas chamber, brake slipper 1, load steel backing 2, the return spring 3 of brake slipper and load steel backing, it is provided with cylinder 4, cylinder piston 5, opposite side at cylinder piston is provided with and the interactional spring 6 of cylinder piston, it also is provided with by the lever 7 of cylinder piston effect, during parking braking, lever drives brake slipper and the motion of load steel backing.Drawing reference numeral 19 is the cylinder diaphragm.
The utility model is provided with the supporting frame 21 with supporting baffle 8 in the annular, this supporting frame is the installation and the load part of whole break, be provided with the annular air-pocket diaphragm 9 that the cross section is ∑ shape on the interior supporting baffle successively, thermal insulating pad 10, and surround above-mentioned sealed gas chamber by ∑ shape air bag diaphragm and interior supporting baffle, load steel backing 2 and brake slipper 1 are located on the thermal insulating pad successively, brake slipper along the circumferential direction, be the polylith shape, has the supporting pin 12 that is connected on the inner support frame between the brake slipper, the other end of supporting pin is connected on the shell, return spring is between supporting pin and the steel backing, brake slipper is provided with radiating groove 13, interior supporting baffle is provided with the radiation hole 14 of break outside sealed gas chamber, break also can be provided with heat radiation fan blade 22.
Lever drives brake slipper and the motion of load steel backing can be by being provided with the parking braking top board 23 that acts on steel backing on the lever.Like this, can not influence the structure of sealed gas chamber, and braking is more reliable.The width of steel backing is greater than brake slipper, and steel backing extends abutting end with the parking braking top board to both sides.Like this, can carry out in the outside of air bag diaphragm with the force transmission of steel backing and brake slipper, and can the sealing of sealed gas chamber not had a negative impact.Certainly, this transfer mode also can adopt multiple mode, such as push rod, pin or the like.
Present embodiment is provided with and acts on separating of lever and stay shift fork 15, and acts on separating of shift fork and stay helix bar 16.
When driving, cylinder is in inflated condition, and spring 6 is by Piston Compression, and at this moment, lever is in free state, and brake slipper is in disengaged position by the return spring effect with brake drum.When service brake,, hold out against on brake slipper and the steel backing to connect airtight and touch brake drum 20 and the realization service brake to the sealed gas chamber inflation that surrounds by ∑ shape air bag diaphragm and interior supporting baffle, when brake off, with the sealed gas chamber venting,, make brake slipper break away from brake drum by the effect of return spring.
When parking braking, to cylinder venting, pushed back at the effect lower piston of the powerful spring-back force of spring 6, drive lever work, and drive the parking braking top board, make steel backing closely be contacted brake drum 20 by last act and realize parking braking with brake slipper.When brake off, to cylinder charge, piston-advance, spring 6 is by Piston Compression, and at this moment, lever is in free state again, and brake slipper is subjected to the effect disengaging of return spring and contacting of brake drum.
In application, separate in shift fork 15 reconciliation and play the reserve safety effect in helix bar 16, its objective is, just in case break down, parking braking can manually be removed, promptly, adjusting is separated in helix bar 16, make to separate in shift fork 15 and force to depress lever, remove the active force to brake slipper, brake slipper breaks away under the effect of return spring and the contacting of brake drum.
