Background technique
Friction type is adopted in the power clutch of differential mechanism more in the existing automobile, but the torque efficiency that friction type differential mechanism power system is transmitted is not high, and differential mechanism must have bigger axial pressure when using.
Chinese patent notification number CN1532436A on September 29 2004 day for announcing, discloses a kind of differential mechanism that is used for wheeled motor vehicle and has comprised a differential gear unit and a differential casing that is used for holding above-mentioned differential gear unit.Above-mentioned differential casing can be around its spin axis forward and counterrotating in the position that is higher than the lubricant oil pasta.Above-mentioned differential casing comprises a part, has an oil-in of running through therebetween on it, and this oil-in is communicated with the inside and outside of differential casing; And an oil draws structure, when differential casing rotates around spin axis, its draw lubricant oil impel lubricant oil to pass through above-mentioned oil-in to get into differential casing inner.But friction type is adopted in the power clutch of this differential mechanism, and the torque efficiency that differential mechanism transmits is not high, and differential mechanism must have bigger axial pressure when using.
The model utility content
The purpose of the utility model is to provide a kind of differential mechanism power cut system; Friction type is adopted in the power clutch that has solved differential mechanism in the existing automobile more; But the torque efficiency that friction type differential mechanism power system is transmitted is not high, and differential mechanism must have the problem of bigger axial pressure when using.
For solving the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of differential mechanism power cut system; Comprise differential mechanism and power input shaft; Be connected with the differential mechanism input shaft on the differential mechanism, the removable link that is socketed with of the axle head of said differential mechanism input shaft, the differential mechanism input shaft is connected through link with power input shaft; Said link outer surface is provided with circular groove, and the circular groove inside lap has shift fork.The power normal delivery, differential mechanism input shaft and power input shaft are through the link engagement, and differential mechanism input shaft and power input shaft are connected as a single entity; The efficient of comparing transmitting torque with the transmission of employing friction type is high; But transmitting torque is big, need not axial force, and is safe and reliable during transferring power; Link is removable, cuts off the transmission of power like needs, then controls shift fork link is moved along the differential mechanism input shaft, and link is thoroughly separated with power input shaft, and moment of torsion can cut off or connect in transmittance process at any time, and is easy to operate.
As preferably, the axle head diameter of axle of the axle head of said differential mechanism input shaft and power input shaft is identical, and differential mechanism input shaft and power input shaft surface are provided with chute, and chute and link internal surface match, and differential mechanism input shaft and power input shaft are through the link socket.Through the chute on differential mechanism input shaft and power input shaft surface, convenience makes the differential mechanism input shaft cut off with power input shaft through mobile link or is connected.
As preferably, said differential mechanism input shaft is outside equipped with casing, and differential mechanism input shaft and power input shaft joint and shift fork are wrapped in the casing.Through being set, casing prevents that differential mechanism power cut system from receiving outside destroy.
As preferably, be connected with bearing between said power input shaft and casing.Guarantee that through bearing is set power input shaft rotates smoothness, stablize power input shaft, prevent that power input shaft from rocking, improve the working life of power input shaft.
As preferably, said bearing arranged outside has bearing cap.Through bearing cap, prevent that outside dust storm from getting into the infringement bearing, guarantees that bearing normally uses.
The beneficial effect of the utility model is: the efficient of (1), this differential mechanism power cut systems communicate moment of torsion is high, but transmitting torque is big, and is safe and reliable during transferring power, separates thoroughly; (2), differential mechanism power cut system controls simply, it is little to take up space.
