What is the principle of the reverse gear in a transmission?

[StMadeline]

The working principle of the transmission reverse gear is to switch the driving gear on the intermediate shaft by moving the gear lever, thereby engaging different gear combinations with the power output shaft to change the torque, speed, and direction of the drive wheels. Precautions for using the reverse gear are as follows: Come to a complete stop before shifting into reverse: When shifting into reverse, it is important to press the brake pedal firmly and ensure the vehicle is completely stopped before engaging the gear. This is because most private cars are not equipped with synchronizers, and shifting without stopping can easily cause gear grinding. Reverse at a slow speed: When reversing, avoid excessive speed and refrain from aggressively pressing the accelerator to accelerate quickly. Doing so can cause significant damage to the straight-cut gears. Additionally, the power transmission of straight-cut gears is very direct and lacks smoothness, so reversing at high speeds can make passengers feel very uncomfortable and generate considerable noise.
