  • Patent number: 9409477
    Abstract: A transmission system for an electric vehicle includes a gearbox which produces different rotation ratio between a drive motor and drive wheels during running of the electric vehicle, a differential which serves to absorb a power of the gearbox to overcome rotation speed difference between the drive wheels, and two wheel axles which are used to deliver the power to the drive wheels from the differential, the gearbox has a housing which is connected to a vehicle frame of the electric vehicle via a universal coupling. When the electric vehicle runs on a bumpy road and makes a turn, the vehicle frame is able to swing up and down and pivot left and right with respect to the gearbox housing, so as to reduce the bounce of the vehicle and dampen the centrifugal force caused tilt or roll of the vehicle, thus improving driving comfort and stability.

  • Patent number: 8978855
    Abstract: A clutch type driving mechanism used in a hybrid powered vehicle is disclosed to include an axle housing mounted at a motor shaft of a motor, a sliding sleeve having a female thread meshed with a male thread of the axle housing, an axle bearing mounted in the sliding sleeve, an input shaft rotatably and slidably supported in the axle bearing with its one end normally kept apart from the axle housing and its other end provided with a gear, and an output shaft meshed with the gear of the input shaft. When the motor is started, the axle housing is driven by the motor shaft to rotate the sliding sleeve, and the sliding sleeve is moved along the axle housing toward the motor due to the effects of inertia, causing friction engagement between the input shaft and the axle housing so that the axle housing can drive the input shaft to transfer rotational motion to the output shaft.

  • Patent number: 8652000
    Abstract: A clutch type driving mechanism used in a hybrid powered vehicle is disclosed to include a motor, a speed reducing mechanism, a hollow shaft, an output shaft and first and second one-way clutches. The motor provides a rotational kinetic energy through the hollow axle to the speed reducing mechanism. The speed reducing mechanism and the output shaft transfer a unidirectional rotary motion to the hollow shaft through the first one-way clutch and the second one-way clutch respectively. Thus, when the output shaft works as a drive shaft, it does not transfer the rotary motion to the speed reducing mechanism, avoiding power loss and allowing transfer of the rotational kinetic energy rapidly and efficiently without bearing much load.
