The paper summarizes the principle of applying velocity graphic method to analyze Simpson planetary gear mechanism, which provides guidance for analysis procedure. The movement of each element in the mechanism can be intuitively understood through drawing the linear velocity vectors of three constant velocity points. The similar triangle principle is used to calculated transmission ratio of each transmission scheme in the linear velocity vector diagram, and the correctness of the analysis method and process is verified by the transmission ratio calculated by velocity graphic method and analytic method.

The power performance and fuel economy could be improved by increasing the shift. The 01N automatic transmission was a Navgneaus planetary gear mechanism with four forward gears, and the 6-speed transmission scheme was achieved by the planetary in series with the Navgneaus planetary gear mechanism. The original lever method was expanded for its limitation, the 6-speed transmission mechanism can be analyzed perfectly by the expanded lever method. The lever method was validated accurate and feasible.

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.

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.
