Embodiment Construction

[0020] Refer to the following Figure 1 to Figure 8 Several exemplary embodiments of the present invention will be described.

[0021] refer to Figure 4 According to one embodiment, the vehicle is equipped with: a driving force source including an engine 201 and / or a motor generator 203; a transmission mechanism 205 for changing the speed of the rotation generated by the driving force source; and distributing the transmitted torque to the left and right front axles 209 the front differential 207; and the front wheels 211 respectively combined with the front differential 207. In a four-wheel drive vehicle, part of the torque of the driving force source is extracted by the power output device 213 , transmitted to the rear differential 219 via the drive shaft 217 , and distributed to the left and right rear axles 221 to drive the rear wheels 223 .

[0022] Motor generator 203 is supplied with electric power from the battery, and supplies torque to the vehicle without using eng...

Abstract

Disclosed is a power transmission device that disconnectably transmits a torque between a first rotary member and a second rotary member that are each rotatable about a shaft, said power transmission device comprising: a clutch that disconnectably and drivably connects said first rotary member and said second rotary member; a motor including a rotor that is rotatable about said shaft; an input member that is rotatable about said shaft by being connected to said rotor, and that has an eccentric shaft that is eccentric to said shaft; a fixed member that is immovable about said shaft; an intermediate member that undergoes eccentric movement by fitting with said eccentric shaft, and that causes rotary movement about said eccentric shaft by meshing with said fixed member; an output member that is rotatable about said shaft, and that follows said intermediate member by engaging therewith; and a cam mechanism that is interposed between said output member and said clutch, and that converts the rotary movement of said output member into movement in the direction of said shaft and presses said clutch.

Description

technical field [0001] The present invention relates to a power transmission device capable of disengaging torque transmission between two rotating members, and more particularly to a differential device for use in combination with a differential device for distributing torque to the axles of a vehicle to control torque transfer from the drive shaft to the differential device power transmission device. Background technique [0002] In a part-time 4WD vehicle, for example, only the front wheels are always connected to the transmission, while the rear wheels are connected depending on the situation. For the purpose of automatically connecting the rear wheels or according to the driver's operation, a power transmission device including a clutch is sometimes used, interposed between the drive shaft and the rear differential, for example. [0003] In such a device, what kind of driving device is used to connect the clutch is one of the technical issues. The drive shaft is given...
