  • Hybrid power driving system and the driving method
    Patent number: 8307925
    Abstract: The present invention provides a hybrid power driving system comprising: a first subsystem designed to input/output power; a second subsystem designed to input/output power; a driving shaft designed to receive power from the first subsystem and/or the second subsystem or output power to the first subsystem and/or the second subsystem; and a tri-stated overrunning clutch designed to connect the first subsystem and the second subsystem, wherein the tri-stated overrunning clutch may be in an overrun state, an engaged state, or a disengaged state. The first subsystem and the second subsystem can comprise an engine, a motor, and a clutch, etc., respectively. In such a hybrid power driving system, when the tri-stated overrunning clutch is in the engaged state, the first subsystem and the second subsystem are coupled to each other and work together.

  • HYBRID POWER DRIVING SYSTEM AND THE DRIVING METHOD
    Publication number: 20100184559
    Abstract: The present invention provides a hybrid power driving system, comprising: a first subsystem (401) designed to input/output power; a second subsystem (402) designed to input/output power; a driving shaft (500) designed to receive power from the first subsystem (401) and/or the second subsystem (402) or output power to the first subsystem (401) and/or the second subsystem (402); and a tri-stated overrunning clutch (400) designed to connect the first subsystem (401) and the second subsystem (402), wherein the tri-stated overrunning clutch (400) may be in an overrun state, an engaged state, or a disengaged state. The first subsystem (401) and the second subsystem (402) can comprise an engine, a motor, and a clutch, etc., respectively. In such a hybrid power driving system, when the tri-stated overrunning clutch is in the engaged state, the first subsystem (401) and the second subsystem (402) are coupled to each other and work together.
