Abstract
The invention discloses a parking brake, and belongs to the technical field of brakes. The parking brake comprises a spring, an end cover, a brake piston, a brake puck, a friction plate and a brake shell, wherein the brake puck and the friction plate are matched for use in a cavity formed by the brake piston and a transmission shaft. The brake piston and the brake puck are both connected with one end of the spring, the other end of the spring is fixed on the end cover, and the brake shell connected with the end cover is arranged on the periphery of the brake piston. The brake puck is connected with the brake shell through an outer spline, the friction plate is connected with the transmission shaft through a spline shaft, the brake shell is of a full-seal structure, and cooling oil liquid is filled in the brake shell. The brake not only avoids influence of water, dust, impurities and the like, but also is rapid and stable in a brake process, improves brake moment of force, and reduces wastage and maintaining costs of equipment.
Description
Technical field
The invention belongs to the break technical field, particularly a kind of Parking Brake.
Background technique
Parking Brake is used for stablize vehicle in the vehicle back of coming to a complete stop, when avoiding vehicle to stop on the road surface, slope owing to the slide car causes the accident.When coal mine operation, Parking Brake is had higher requirement, need braking moment greatly and can adapt to bad working environment.Traditional Parking Brake unstable properties, equipment loss is bigger, needs often equipment to be safeguarded, has increased cost of production.
Summary of the invention
Goal of the invention: at the deficiencies in the prior art, the purpose of this invention is to provide a kind of Parking Brake, make it can not only adapt to bad working environment under the coal mine, and it is reliable to operate steadily, equipment loss is low, is easy to maintenance and maintenance.
Technological scheme: in order to realize the foregoing invention purpose, the technical solution adopted in the present invention is:
A kind of Parking Brake comprises spring, end cap, brake piston, brake puck, friction plate and brake casing, is provided with brake puck and the friction plate that is used in the cavity of described brake piston and transmission shaft formation; Described brake piston all links to each other with an end of spring with brake puck, and the other end of spring is fixed on the end cap; Periphery at described brake piston is provided with the brake casing that links to each other with end cap; Wherein, described brake puck links to each other with the braking housing by external splines, and described friction plate links to each other with transmission shaft by splined shaft; Described brake casing is all-sealed structure, is filled with cooling oil in the inside of brake casing.
Between described brake casing and brake piston, be provided with seal ring.
The both sides of described friction plate are porous fibre face structure.
Described brake puck and friction plate are crisscross arranged in the cavity of brake piston and transmission shaft formation.
Beneficial effect: compared with prior art, Parking Brake of the present invention by adopting full-enclosed structure, has been avoided the influence of moisture, dust, impurity etc.; Friction plate by be crisscross arranged brake puck and porous fibre face, the control of employing pressure oil, make braking process rapidly, steadily, reliable and safety, improved braking moment, loss and the maintenance cost of equipment have been reduced, make coal mine operation more safe and reliable, suit in producing running, to apply.
Description of drawings
Fig. 1 is the structural representation of Parking Brake.
Embodiment
The present invention is further described below by specific embodiment; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the principle of the invention; can also make some modification and improvement, these also should be considered as belonging to protection scope of the present invention.
As shown in Figure 1, Parking Brake comprises spring 1, end cap 2, brake piston 3, brake puck 4, friction plate 5, seal ring 6 and brake casing 7, in the cavity that brake piston 3 and transmission shaft form, be provided with brake puck 4 and the friction plate 5 that is used, brake piston 3 all links to each other with an end of spring 1 with brake puck 4, and the other end of spring 1 is fixed on the end cap 2; Periphery at brake piston 3 is provided with the brake casing 7 that links to each other with end cap 2, is provided with seal ring 6 between brake casing 7 and brake piston 3; Wherein, the both sides of friction plate 5 are the porous fibre face; Brake puck 4 links to each other with braking housing 7 by external splines, and friction plate 5 links to each other with transmission shaft by splined shaft, and brake puck 4 and friction plate 5 are crisscross arranged in the cavity that brake piston 3 and transmission shaft form; Brake casing 7 is all-sealed structure, is filled with cooling oil in the inside of brake casing 7.
Working procedure: brake puck 4 links to each other with brake casing 7 by external splines, and friction plate 5 is connected with transmission shaft by splined shaft, makes Parking Brake rotate with transmission shaft; When needing braking, fluid from brake valve enters Parking Brake, brake piston 3 axially moves under the driving of hydraulic oil, by first brake puck 4 other brake puck and the gap between the friction plate 5 are eliminated until compressing the purpose that reaches braking mutually, spring 1 is also compressed accordingly simultaneously; After braking discharged, hydraulic oil was removed, and brake piston 3 resets under the effect of compression spring 1 gradually, and brake puck 4 and friction plate 5 are thrown off, and braking is eliminated, and spring 1 resets.
This Parking Brake by adopting full-enclosed structure, has been avoided the influence of moisture, dust, impurity etc.; Friction plate by be crisscross arranged brake puck and porous fibre face, the control of employing pressure oil, make braking process rapidly, steadily, reliable and safety, improved braking moment, loss and the maintenance cost of equipment have been reduced, make coal mine operation more safe and reliable, suit in producing running, to apply.
