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.
1. A vehicle drivetrain device configured to be mounted between a vehicle frame and a wheel axle of a vehicle, the vehicle drivetrain device comprising:
a driving assembly comprising
a transmitting mechanism having
a pivotal end pivotally connected to the vehicle frame; and
a connecting end directly connected to the wheel axle by a gear set;
a driving mechanism mounted at a side of the transmitting mechanism, being moveable curvedly relative to the vehicle frame when the transmitting mechanism is pivoted relative to the vehicle frame, and configured to output power to the transmitting mechanism; the transmitting mechanism transferring the power outputted by the driving mechanism to the wheel axle; and
a shock absorber mounted between the vehicle frame and the driving assembly, and configured to provide shock absorbing and buffering functions between the vehicle frame and the driving assembly.
2. The vehicle drivetrain device as claimed in claim 1 , wherein the transmitting mechanism of the driving assembly has
a pivotal portion pivotally connected to the vehicle frame; and
a connecting portion connected to the wheel axle.
3. The vehicle drivetrain device as claimed in claim 1 , wherein the transmitting mechanism of the driving assembly comprises
a transmitting mechanism body having
a connecting portion connected to the wheel axle;
a linking portion; and
a converting plate fixedly mounted on the linking portion of the transmitting mechanism body, and pivotally connected to the vehicle frame.
