Embodiment
In order that those skilled in the art more fully understand the utility model, below in conjunction with the accompanying drawings and it is embodied
The utility model is described in further detail for mode.
It refer to Fig. 1-2, a kind of wet friction brake that the utility model embodiment provides.
The wet friction brake is located at the outside of the driven gear 2 of automobile differential 1, adjacent with driven gear 2 and surround
On output shaft 3.
Wet friction brake includes shell 4, friction component 5, piston 6, piston controller 7 and heat abstractor 8.
Friction component 5 and piston 6 are installed in shell 4, filled with cooling oil in shell 4, friction component 5 is dipped in cooling
In oil.Cooling oil can be such that friction component 5 is cooled down faster, avoid friction component 5 from braking effect after a protracted use
Fruit weakens.
Friction component 5 designs for multiple-piece, is alternately formed by stacking by inner attrition piece 51 and outside friction disc 52, inner attrition piece 51
For circular friction plates and it is configured on output shaft 3, outside friction disc 52 is annular friction piece, and output shaft 3 passes through among annular.System
When dynamic, interior outside friction disc is compacted, and produces friction engagement, because inner attrition piece 51 is built on output shaft 3, friction engagement makes
Inner attrition piece 51 stops the rotation, so that output shaft 3 stops the rotation, reaches the purpose of braking.Multiple-piece design can make friction
Component produces bigger brake force when being compacted, and reaches more preferable braking effect.
Piston 6 is also surrounded on output shaft 3, and can be moved along the axial direction of output shaft 3.Piston controller 7 and piston 6
Connection, such as the movement by oil cylinder control piston 6.
Piston controller 7 can be according to the position for needing to control piston 6 of user, and regulating piston 6 is to friction component 5
Compression degree, to control brake force or speed, realize cruise or non-cruise pattern.Piston controller 7 except
It can use outside oil cylinder, can also be realized using drive mechanism known to cylinder, electric pushrod etc..
Heat abstractor 8 is connected located at the outside of shell 4 by cooling down oil circulating system 9 with shell 4.Heat abstractor 8 can be
Aerial cooler or water-filled radiator, using aerial cooler in the present embodiment.Heat abstractor 8 can will pass through cooling oil
The cooling oil cooling that the circulatory system 9 is entered inside heat abstractor 8, and by the cooling oil after cooling by cooling down oil circulating system
It is passed into the cooling that friction component 5 is carried out in shell 4.
Cooling oil circulating system 9 also includes an oil pump 10 in addition to being communicated in the pipeline of the inside of shell 4 and heat abstractor 8
With hydraulic pump control system 11.Oil pump 10 can be such that cooling oil is circulated in oil circulating system 9 is cooled down, and hydraulic pump control system
11 temperature sensors for including controller and being arranged in cooling oil circuit piping.Controller can be independently arranged at oil pump 10
Outside, it can also be integrated in oil pump 10 and realize control (such as frequency conversion oil pump).Controller can be according to cold in cooling oil circulating system 9
The speed of service of the demand modeling oil pump 10 of oily temperature and user, the speed of cooling oil circulation is adjusted in real time, more preferably
Lifting solid stop cooling effect.
The wet friction brake can according to be actually needed located at vehicle front axle or rear axle or be located at antero posterior axis simultaneously.
Further, by the wet friction brake on vehicle, the function of going up a slope and aid in can also be realized：
The transport condition of vehicle is sensed by the electronic component in vehicle, is automatically switched to when vehicle enters uphill way
Slope auxiliary mode, for vehicle when providing power climbing, the electronic component control piston controller 7 in vehicle moves piston 6, makes
Piston 6 loosens, and brake does not work；When vehicle does not provide power or speed is 0, the electronic component control piston control in vehicle
Device 7 processed moves piston 6, makes the pressing friction device 5 of piston 6, and brake plays braking action, prevents vehicle from being glided along slope.
It is similar, approximate technology is aided in using with going up a slope above, by the GPS system or camera device outside connection,
This brake can also be realized according to road automatic speed-limiting and run into the self-stopping function of emergency.
Wet friction brake provided by the utility model is described in detail above.It is used herein specifically
