What is the reason for oil leakage from the vent hole on the transmission?
1 Answers
After driving, the internal gears of the transmission heat up, causing the transmission oil to also heat up, which results in the expansion of the transmission volume. Below is an introduction to the transmission: 1. Main functions: Changing the transmission ratio to expand the range of torque and speed variations of the drive wheels, adapting to frequently changing driving conditions, while allowing the engine to operate under favorable conditions. It enables the car to reverse while keeping the engine's rotation direction unchanged. By using neutral gear, it interrupts power transmission, allowing the engine to start, shift gears, and facilitating gear changes or power output. 2. Working principle: A manual transmission mainly consists of gears and shafts, achieving speed and torque changes through different gear combinations. An automatic transmission (AT) is composed of a torque converter, planetary gears, and a hydraulic control system, achieving speed and torque changes through hydraulic transmission and gear combinations.
