VEHICLE DRIVETRAIN DEVICE

A vehicle drivetrain device, configured to be mounted between a vehicle frame and a wheel axle of a vehicle, comprises a driving assembly and a shock absorber, connected to the vehicle frame and the driving assembly. The driving assembly comprises a transmitting mechanism, pivotally connected to the vehicle frame and connected to the wheel axle, and a driving mechanism mounted at a side of the transmitting mechanism and outputting power to the wheel axle through the transmitting mechanism. The driving assembly of the vehicle drivetrain device possesses functions of a rear rocker arm and provides power. Therefore, a space between the vehicle frame and the wheel axle can be used efficiently, and the occupancy of a usable space below the vehicle frame is decreased. Furthermore, the transmitting mechanism can be directly connected to the wheel axle by a gear set, simplifying a total structure, thereby lowering the cost.
