Dual-motor driving type intelligent transmission speed change system

Abstract

The invention discloses a dual-motor driving type intelligent transmission speed change system, which is characterized in that a speed reduction mechanism, a forward gear and a reverse gear are sequentially arranged on an output shaft; a cam clutch mechanism is arranged between the forward gear and the output shaft; a first input shaft is driven by a first motor; a first forward gear, a first shifting fork and a back-up gear are arranged on the first input shaft; the first forward gear and the back-up gear are both in running fit with the first input shaft and are meshed with the forward gearand the reverse gear respectively; the first shifting fork is installed on the first input shaft through a spline; the second input shaft is driven by a second motor; and a second forward gear meshedwith the forward gear is arranged on the second input shaft. The invention has the beneficial effect that the self-locking of the speed change system can be prevented in a reversing mode. Dual-motor power input is adopted, a load detection mechanism is arranged so that the load of the transmission is measured in real time, the actual output condition of a motor is selected through feedback of theload, and the acceleration performance and the climbing performance of the speed change system are improved.

Description

technical field [0001] The invention relates to an electric drive speed change mechanism, in particular to a dual-motor driven intelligent transmission speed change system. Background technique [0002] The transmission is a mechanism used to coordinate the engine speed and torque, which can change the transmission ratio between the output shaft and the input shaft to make the engine perform optimally. Transmissions are widely used in modern machinery, such as motorcycles, automobiles, aviation, ships and other fields. [0003] Undoubtedly, with the continuous deepening of research and development of transmission mechanisms, automatic transmissions capable of automatic gear shifting have become the mainstream of the market. In recent years, whether in the international or domestic market, the requirements for automatic transmissions have become higher and higher, because the quality of automatic transmissions has played an important role in the driving experience, vehicle p...
