Embodiment Construction
[0054] figure 1 is a structural schematic diagram of the transmission device according to an embodiment of the present invention. combine figure 1 To illustrate, the transmission device for a hybrid vehicle may include: an output shafting component 400 , an intermediate transmission component 200 , a drive motor 301 and a reverse shafting component 300 . The output shafting component 400 is used to drive the vehicle. The intermediate transmission part 200 is used to transmit the power output by the vehicle's engine 101 or / and the drive motor 301 to the output shaft system part 400 according to various transmission ratios, which is connected to the vehicle's engine 101 . The drive motor 301 is used to drive the vehicle independently or jointly with the engine 101 of the vehicle, and has a motor output shaft 302 . The reverse shafting part 300 is used to transmit the output power of the driving motor 301 to the output shafting part 400 via the intermediate transmission part ...

The invention provides a transmission device for a hybrid power vehicle and relates to a transmission device. The transmission device comprise an output shaft system part, an intermediate transmission part, a driving motor and a reverse gear shaft system part, wherein the output shaft system part is used for driving the vehicle; the intermediate transmission part is used for transferring power output by an engine of the vehicle or / and a driving motor to the output shaft system part according to various transmission ratio forms, wherein the intermediate transmission part is in transmission connection to the engine of the vehicle; the driving motor is used for independently driving the vehicle or jointly driving the vehicle with the engine of the vehicle, wherein the driving motor is provided with a motor output shaft; and the reverse gear shaft system part is used for transferring the power output by the driving motor through the intermediate transmission part or / and directly transferring the power output by the driving motor to the output shaft system part, wherein the reverse gear shaft system part is coaxially connected to the output shaft of the driving motor. The basic function of the transmission device which can provide various transmission ratios is effectively realized while the size of the transmission device is further reduced.
Description
technical field [0001] The present invention relates to a transmission device, in particular to a transmission device for a hybrid vehicle. Background technique [0002] The transmission is a mechanism used to change the speed and torque from the engine. It can change the transmission ratio of the output shaft and the input shaft in fixed or stepwise steps, also known as the gearbox. Speed changer is made up of speed change transmission mechanism and operating mechanism. Most of the transmission mechanisms are driven by ordinary gears, and some are driven by planetary gears. Ordinary gear transmission transmission mechanisms generally use slip gears and synchronizers. [0003] At present, for the transmission of an electric-driven hybrid vehicle, it is often required to be independently driven by the engine, independently driven by the motor, or hybridly driven by the motor and the engine. Output power in different transmission ratio forms. [0004] Therefore, the stru...
