Problems solved by technology

[0009] In the prior art, the above-mentioned automatic transmissions are mostly used in small vehicles due to small transmission torque, large transmission impact, long shift time, or complicated control, while large vehicles such as trucks still can only rely on manual transmissions To achieve speed change, these large vehicles are limited by the engine speed, which requires the driver to react and operate quickly when changing speed, and has high requirements for the driving skills of the driver. If the automatic speed change of large vehicles can be realized, it can effectively reduce the speed The difficulty of driving has a positive effect on the development of the transportation industry and other industries that require the use of large vehicles

Abstract

The invention discloses an automatic transmission without cutting off power, which relates to the field of automatic transmissions for new energy vehicles, and includes an input shaft, a transmission shaft, a first planetary gear mechanism, a second planetary gear mechanism, a first motor and a second motor; The shaft and the transmission shaft rotate synchronously with the ring gear and the sun gear of the first planetary gear mechanism; the planet carrier of the first planetary gear mechanism drives the planet carrier of the second planetary gear mechanism to rotate synchronously; the planet carrier of the first planetary gear mechanism and the transmission A clutch is arranged between the shafts; the sun gear of the second planetary gear mechanism is fixedly connected to the rotor of the first motor, the transmission shaft is fixedly connected to the rotor of the second motor, and the stator of the first motor and the stator of the second motor are both connected to the second planetary gear. The ring gear of the gear is fixedly connected. It has high transmission efficiency, large transmission torque, smooth shifting without impact, and can realize energy recovery.

Description

Technical field [0001] The present invention relates to the field of new energy automotive automatic transmission, and is specifically a non-cutting power shift automatic transmission. Background technique [0002] Currently, automotive automatic transmission includes five transmission of CVT, DSG, AT, AMT, and hybrid driven ECVT. [0003] Among them, the conveying efficiency of the CVT automatic transmission is high, and the speed is smooth. There is no power interruption when shifting. When the shift is required, the engine speed mutation, the transfer, the shift continuous, the engine output torque curve is not strict, and the vehicle acceleration is good; Its transmission torque is small, and the speed ratio of the transmission is smaller, and the fault rate is high. [0004] The DCT automatic transmission is high, the theoretical shift time is short, the transfer torque is large, the shock shock is smaller, the acceleration performance of the vehicle is good; but the engine ...
