Description

Heat rejecting clutch can for new-energy automobile

Technical field

A kind of heat rejecting clutch can for new-energy automobile is the utility model is related to, belongs to clutch can technical field.

Background technology

Existing constant velocity driving shaft assembly all includes clutch can, there is steel ball and retainer inside clutch can, steel ball and bell Shell inner surface rolling friction.While clutch can is worn, due to the continuous frictional between each component, the temperature in clutch can Degree can be higher than ambient temperature, if these heats cannot be evacuated in time, will further speed up the rate of wear between each component, Ultimately resulting in component cannot use, and usually can also be cased with dirt-proof boot at the port of clutch can, this just further results in clutch can Interior heat is not easy to lose, and at present, the cooling measure on clutch can only be solved in theory mostly, does not provide one also The practical available mode of kind, in order to solve deficiency of the prior art, it is necessary to be made further research to the cooling measure of clutch can.

The content of the invention

The purpose of this utility model is to provide a kind of heat rejecting clutch can for new-energy automobile, so as to solve existing Heat accumulates in the problem of inside cannot distribute to clutch can in use, the performance for clutch can of deducting a percentage.

A kind of heat rejecting clutch can for new-energy automobile, including clutch can body, Internal Spherical Surface, rear boss, installing handle, Wherein there is Internal Spherical Surface in clutch can body, rear boss, installing handle connection rear boss, its feature are set in the rear end of clutch can body It is：The outer rim of the rear boss is uniformly arranged some outer exhaust pipes, and the external port of outer exhaust pipe is directed toward same rotation direction, and outer row The inner port of tracheae is connected in the inside exhaust pipe of clutch can body interior；If the rear end face of the rear boss is circumferentially distributed Dry intermediate tube, the inner port of intermediate tube are connected in the interior air inlet pipe of clutch can body interior；The external port of the intermediate tube External admission pipe is installed, the external port of all air inlet pipe is and opposite with the external port direction of outer exhaust pipe towards same rotation direction； Baffle ring is set on intermediate tube, has adapter sleeve to be sleeved on intermediate tube between the baffle ring and rear boss；The external admission pipe rear end It is sleeved on intermediate tube, and external thread section is set in outer air inlet pipe rear port outer rim, male end coordinates with adapter sleeve.

The rear portion of the clutch can has added the external port of inlet channel and outlet passageway, wherein the external admission pipe of inlet channel The unified forward direction for being directed toward clutch can, and the external port of the outer exhaust pipe of outlet passageway then with the external port of external admission pipe It is directed toward on the contrary, when clutch can body is in high-speed rotation under the action of drive shaft, cool air enters in clutch can from external admission pipe Portion, be in negative pressure state inside outer exhaust pipe at this time, is flowed into the air driven heat inside clutch can, and from outer exhaust pipe Discharge, achievees the purpose that to reduce clutch can temperature, so as to reduce the friction dynamics of clutch can and assembly parts, lifting clutch can uses Performance.

Preferably, the rear portion of rear boss is equipped with the dust cover being sleeved on installing handle, and the leading edge of dust cover is With female mounting ring, correspondingly the back edge of rear boss is equipped with screws thread segment with what mounting ring coordinated, and described anti- The position contacted on dust hood with installing handle is equipped with dust cover sealing ring.During clutch can high-speed rotation, outside air enters external admission Pipe, at this time may bring dust inside clutch can into, this, which may result in, is unable to flexible rotating between clutch can and assembly parts, if The entrance of dust can effectively be reduced by putting dust cover.

Preferably, the baffle ring rear end face sets air packing.It is for ease of manufacturing and replacing, external admission pipe is independent Design, to ensure the air-tightness being sleeved between the external admission pipe of intermediate tube and suit on it, sets air packing, this can have Effect ensures air inflow, improves the cooling efficiency to clutch can.

Preferably, the external admission pipe position adjacent with rear boss trailing flank is equipped with and determines perpendicular to rear boss Position axis, correspondingly sets location hole on rear boss, and locating shaft coordinates with location hole to be installed.Locating shaft and location hole are set, can To provide enough support forces to external admission pipe, prevent that external admission pipe loosens deflection during high-speed rotation.
