Does BYD DM-i Have a Transmission?
1 Answers
BYD DM-i does not have a transmission. The functions of a transmission are as follows: Changing the gear ratio: Expanding the range of torque and speed variation for the driving wheels. Facilitating gear shifting: Using neutral gear to interrupt power transmission, allowing the engine to start, change speed, and facilitating gear shifting or power output. Classification of automotive transmissions: Divided into manual and automatic types. Manual transmissions mainly consist of gears and shafts, achieving speed and torque variation through different gear combinations; while automatic transmissions (AT) are composed of a torque converter, planetary gears, and a hydraulic control system, achieving speed and torque variation through hydraulic power transmission and gear combinations.
