It is concentrated with stress, friction facing is caused to generate buckling deformation, so circulation is gone down, thermo-contact state and contact pressure can be made to become
Change aggravation, generate high temperature hotspot, hot spot be in wet brake braking process it is very common, mainly due to braking when it is multiple
Caused by miscellaneous heat engine coupling effect.Although the thermal friction characteristic of brake, which has been one, the problem of many years history, generation
Boundary scholars are to problem involved in it without forming specific understanding.Existing brake can only by external condition into
Row thermal cycle cools down, but practical problem can not solve.
Although existing brake can be realized basic braking function, but there is a problem of it is very much, such as application No. is
201410324845.6 Chinese patent disclose it is a kind of integrate the multi-functional wet multi-disc brake of slow, braking, parking,
The braking system for being mainly used for inclement condition, safeguarding inconvenient various machinery, each component are installed by pedestal of shell, so
Be attached by studs and vehicle bridge afterwards to fix brake, driving wheel connect by coupling bolt with wheel hub, realization and
Wheel rotates synchronously；This product friction plate working chamber is closed chamber, can successfully manage extraneous bad working environments, be passed through and follow in closed chamber
Ring cooling oil can effectively achieve the purpose that reduce temperature rise, reduce loss, and stable working performance, abrasion is little, and use process is general
Adjustment-free；Friction plate use annulus shape, work area is big, and use polydisc structure, can be obtained under smaller liner pressure compared with
Big braking moment；Changing number of friction pairs mesh can be adjusted braking moment, it is easy to accomplish rub secondary standardization；Cooling effect
Fruit is good, and operating temperature is low, long service life, generally 3-5 times of dry brake.Although using and being passed through circulation cooling oil
Mode carries out reduction temperature rise, but cannot fundamentally solve the problems, such as that temperature increases, it is seen then that traditional wet is more in the prior art
