Problems solved by technology

[0006] The disadvantage of this type of structure is that the transmission shaft needs to be connected to the planetary gear members through multiple sets of gears or belts, and the transmission efficiency of the hybrid vehicle is affected. The clutch and the locker cooperate with each other in different working modes, and the structure is complicated. The difficulty in traditional car power chassis is high, and the production cost and post-maintenance cost are relatively high

Abstract

The invention relates to a hybrid power driving device comprising an engine, an engine output shaft, a first clutch, a planetary gear member, an electric motor, a hollow electric motor shaft and a transmission shaft. The hybrid power driving device is characterized in that the engine, the engine output shaft, the first clutch, the planetary gear member, the electric motor and the transmission shaft are sequentially connected on the same axis, the engine output shaft is mechanically connected with a gear ring of the planetary gear member through the first clutch, the hollow electric motor shaft of the electric motor is connected to a solar gear of the planetary gear member, and the transmission shaft passes through the hollow electric motor shaft and is connected with a planetary carrier to transmit the output torques of the engine and the electric motor; and the planetary carrier is mechanically connected with the hollow electric motor shaft through a second clutch.

Description

technical field [0001] The invention relates to a hybrid driving device, in particular to a coaxial planetary gear series-parallel hybrid driving device, which is especially suitable for hybrid vehicles with better fuel economy. Background technique [0002] The power of a hybrid vehicle comes from the engine and the drive motor, and the energy flow is managed through the energy storage device (battery, super capacitor, etc.) High dynamics. [0003] Hybrid vehicles have two power sources. When starting and driving at low speeds, due to the low efficiency of the engine, the hybrid system only uses the power of the electric motor to drive. The efficiency of the engine is very high during normal driving. The power generated by the engine is not only the driving force of the wheels, but also used to drive the electric motor to generate electricity and charge the energy storage device. When decelerating or braking, the hybrid system uses the rotational force of the wheels to dr...
