What is the speed change principle of a transmission?
1 Answers
The speed change principle of a transmission is achieved by the gears on the output shaft driving the gears on the input shaft. A small gear driving a large gear results in speed reduction and increased torque (which is why low speeds are used during startup), while a large gear driving a small gear results in speed increase and reduced torque. It utilizes different gear combinations to achieve speed and torque adjustments. Automotive transmissions are divided into manual and automatic types. Manual transmissions mainly consist of gears and shafts, producing speed and torque changes through different gear combinations. Automatic transmissions (AT) are composed of a torque converter, planetary gears, a hydraulic torque variation system, and a hydraulic control system, achieving speed and torque changes through hydraulic power transmission and gear combinations.
