Breakaway Clutch For Controllable Speed Accessory Drive System |
摘要 |
An accessory drive system for a hybrid vehicle is provided including a planetary gear set having first, second, and third members. A torque transfer device operatively connects an engine with the first member. A motor/generator is operatively connected to the second member. A plurality of vehicle accessories are operatively connected to the third member. A one-way clutch is operatively connected to either the first member of the planetary gear set or the torque transfer device. The one-way clutch is also selectively connected to a stationary member via a breakaway clutch configured to slip when either the input torque exceeds a threshold value or the direction of rotation is opposite of the driving direction. Engine output is transferable through the planetary gear set to drive the accessories at a selectable rate, and the motor/generator is controllable to run the accessories while the engine is off and while restarting the engine.
