Description
Technical field
The present invention relates to break technical field, relate in particular to a kind of sealing configuration for wet brake annular piston.
Background technique
Wet brake is widely used with work under bad environment and needs the special car that braking moment is larger at present.Thereby wet brake is realized braking by the raw braking moment of hydraulic drive piston pressing friction by-product, conventionally adopts O type circle or Y-shaped ring as piston packing, annular piston to be moved back and forth.But O type circle or Y-shaped ring only produce the function that seal action impels piston movement not have to make piston return or carry out brake clearance compensation during as piston packing.Therefore, generally usining O type circle or Y-shaped ring must increase piston returning device and brake clearance compensation device as the wet brake of piston packing.Like this in the design of wet brake and produce and increase cost and difficulty, and extremely inconvenience when wet brake is safeguarded.
Summary of the invention
The object of the invention is to based on the problems referred to above, a kind of sealing configuration for wet brake annular piston is provided, make up and use O type circle or Y-shaped ring only for the function singleness of packed-piston, increase the critical function that makes piston return and carry out brake clearance compensation.
For achieving the above object, the technical solution adopted in the present invention is:
For a sealing configuration for wet brake annular piston, comprise two seal rings 1.1,2.1, interior caliper 1 and annular piston 2, by above-mentioned parts, form annular seal cavity; Wherein, described annular piston 2 is arranged in interior caliper 1; Described two seal rings 1.1,2.1 are arranged on respectively on interior caliper 1 and annular piston 2; On described interior caliper 1 or annular piston 2, be processed with rectangle groove.
Wherein, to have one or two at least be all rectangular seal to described two seal rings 1.1,2.1.
Wherein, install on the interior caliper 1 of described rectangular seal or annular piston 2 and be processed with rectangle groove, interior caliper 1 rectangle groove is provided with an oblique angle and allows rectangular seal to move in piston-advance direction, and annular piston 2 rectangle grooves are provided with an oblique angle and allow rectangular seal to move in the direction with piston-advance opposite direction.
Wherein, the material that described rectangular seal adopts is rubber material.
Beneficial effect
The beneficial effect of the sealing configuration for wet brake annular piston of the present invention is:
Sealing configuration for wet brake annular piston of the present invention has made up and has used O type circle or Y-shaped ring only for the function singleness of packed-piston, increased the critical function that makes piston return and carry out brake clearance compensation, piston returning device and brake clearance compensation device in wet brake structure, have been cut, greatly reduce cost and the design difficulty of wet brake, and safeguard simply, can guarantee well break reliability of operation and traffic safety.
The material that rectangular seal of the present invention adopts is oil resistant, chemical resistance and good physical and mechanical properties and weatherability rubber material, it is characterized in that solving general wet brake and utilized O type circle or Y-shaped ring cannot carry out the problem that piston return and brake clearance are adjusted, reduced the cost of production of this break and maintenance cost and greatly improved the safety and reliability of vehicle.

Embodiment
Below in conjunction with accompanying drawing, the present invention will be described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
As shown in Figure 1, a kind of sealing configuration for wet brake annular piston, comprises two seal rings 1.1,2.1, interior caliper 1 and annular piston 2, by above-mentioned parts, forms annular seal cavity; Wherein, described annular piston 2 is arranged in interior caliper 1; Described two seal rings 1.1,2.1 are arranged on respectively on interior caliper 1 and annular piston 2; On described interior caliper 1 or annular piston 2, be processed with rectangle groove.
Wherein, to have one or two at least be all rectangular seal to described two seal rings 1.1,2.1.
Wherein, install on the interior caliper 1 of described rectangular seal or annular piston 2 and be processed with rectangle groove, interior caliper 1 rectangle groove is provided with an oblique angle and allows rectangular seal to move in piston-advance direction, annular piston 2 rectangle grooves are provided with an oblique angle and allow rectangular seal to move in the direction with piston-advance opposite direction, as shown in Figure 2.
Wherein, the material that described rectangular seal adopts is rubber material.
The working procedure of the described sealing configuration for wet brake annular piston is: when wet brake is braked, pressure oil enters braking cavity, annular piston 2 axially moves, seal ring 1.1,2.1 and then annular piston 2 axially moves together, wherein rectangular seal deforms in movement process in rectangular seal ring recess, as shown in Figure 4, and piston thrust is greater than the frictional force between rectangular seal and interior caliper 1 or annular piston 2, therefore annular piston 2 can continue to axially move until clamp friction pair, formation braking.When pressure is removed, the rectangular seal deforming retreats under elastic-restoring force effect, the elastic-restoring force of rectangular seal is greater than the frictional force between rectangular seal and interior caliper 1 or annular piston 2, thereby annular piston 2 is retreated and unclamp friction pair, brake off, now the gap between annular piston 2 and friction pair can be called braking primary clearance.
While repeatedly braking along with wet brake, friction pair can produce wearing and tearing, when annular piston 2 moves to braking primary clearance, between friction pair, also has wearing clearance.Now, under the effect of pressure oil, piston thrust is greater than the frictional force between rectangular seal and interior caliper 1 or annular piston 2, so annular piston 2 can continue to axially move the wearing clearance of friction compensation pair until clamp friction pair, forms braking.After pressure is removed, annular piston 2 retreats under the effect of the elastic-restoring force of rectangular seal, but changes with respect to the position of annular piston 2 before friction pair generation wearing and tearing, and it is exactly the wearing clearance that rectangular seal compensates that this section moves.
By repeatedly braking, under the effect of interior caliper 1, seal ring 1.1, annular piston 2, seal ring 2.1, the trace wearing and tearing that self-return auto-compensation friction pair produce, keep the brake clearance of initial setting constant.
Finally it should be noted that: obviously, above-described embodiment is only for example of the present invention is clearly described, and the not restriction to mode of execution.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all mode of executions.And the apparent variation of being amplified out thus or change are still among protection scope of the present invention.
