Planetary Gear Mechanism

Recently, technology for electric vehicles (EV) and hybrid vehicles (HEV) has been focused on by the automotive industry to address environmental problems including CO2 reduction [. In particular, in HEV, planetary gears are used to control differential rotation of the motor, engine and generator. For these vehicles, the noise level inside the vehicle is low because the motor is used as the main power source. As a result, further decrease of gear noise is desired compared with the conventional planetary gear mechanism. However, research into the gear noise of the planetary gear mechanism is extremely scarce. Therefore, in this study, we focus on the three axes of I/O rotation, and a new method of measuring the meshing force of the planetary gear mechanism. In this report, a gear-driving device, which is able to make 3-axis differential rotation, was designed for experimentation.

Planetary Gear Mechanism

A novel planetary gear hybrid powertrain is proposed. It contains mainly nine components: A planetary gear mechanism, an internal combustion engine, two motors, two invertors, a set of battery, a power control unit(PCU) and a differential. To further the verification, the feasibility has been demonstrated by system operations analysis. The proposed hybrid powertrain harmonizes the operation of two motors and an engine. It achieves pure electric driving, hybrid driving and regenerative while braking, improves the fuel economy and benefits from the simple configuration, easy assembling and the flexibility of application.
