Background technology
Brake is a kind of for reducing or the mechanical mechanism of arresting stop motion；It is applied in hoisting speed reducer in engineering machinery more, driving speed reducer etc..
For wet multi-disk brake, its principle is: friction plate element engages frequently and separates, by piston pressing friction sheet；When applying to control pressure, friction plate separates, and the separate mode that brake bush is commonly used is for being freely separating mode, and after i.e. applying to control pressure, brake bush relies on free space between friction plate to separate.
Brake at present cannot be used for service brake more: first friction effective area is little, and when larger torque is applied on friction plate, producing a large amount of heat energy cannot distribute, and causes friction plate to burn；Friction plate belongs to easy wearing detail simultaneously, and long-term friction causes friction plate to be decayed, and reduces braking ability.
Current normally closed brake has the disadvantage that
Separate thoroughly when moving plate, still release braking, have slip relatively between friction plate: when the initial stage is opened in brake, owing to not forcing separating mechanism between friction plate, friction plate separates successively, i.e. most external friction plate first separates, separating after penetralia friction plate, this process, it cannot be guaranteed that be sufficiently separated between friction plate, therefore can cause relative sliding friction between friction plate, friction plate is caused bigger abrasion, affects the service life of brake bush.
Summary of the invention
This utility model provides a kind of brake bush automatic separating apparatus, forces to make movable friction plate separate with static friction sheet, reduce abrasion between the two, thus ensure the service life of friction plate during releasing braking.
To achieve these goals, the technical solution adopted in the utility model is: a kind of brake bush automatic separating apparatus, including: housing, the most a piece of movable friction plate, the most a piece of static friction sheet, piston, spring and spline housing；

Described movable friction plate the most mutually compresses with static friction sheet or separates；
Wherein, it is provided with reduction torsion spring (11) in the free space between described movable friction plate and static friction sheet and at spline housing；
Under on-position: clamping piston under the action of the spring, movable friction plate adjacent under the effect of piston mutually compresses with static friction sheet, reduction torsion spring；Release under on-position: adjacent movable friction plate, static friction sheet are forced to separate under the reseting elasticity effect of reduction torsion spring.
The free space that the quantity of the reduction torsion spring between the most adjacent described movable friction plate and static friction sheet is at least between one, and the size of reduction torsion spring and movable friction plate and static friction sheet matches.
Described piston utilizes sealing ring to seal with housing, wherein offers control oil duct on the downside of housing.
Described piston passes on left baffle plate and carries out spacing, and wherein, baffle plate is fixed on spline housing by circlip.
This utility model also includes:
The lubrication channel being arranged on housing, for carrying out forced feed lubrication to movable friction plate and static friction sheet.
