What are the functions of automotive transmission systems

Deceleration and torque increase: Reduce the output speed and multiply the torque to provide the driving force required for starting and climbing the car (the high-speed and low torque characteristics of the engine need to be converted).

Variable speed and direction: Adapt to different vehicle speed requirements by changing the transmission ratio, and achieve reverse driving.

Power interruption and smooth engagement: temporarily cut off power during starting, shifting, or parking to ensure smooth starting and no impact during shifting.

Differential function: allows the left and right drive wheels to rotate at different angular velocities during turning, preventing tire slippage, wear, and difficulty in steering.

Overload protection: restricts the transmission of torque (such as clutch slippage) during emergency braking or wheel jamming, protecting transmission components from damage.

Adapt to relative motion: Compensate for displacement and angle changes between the vehicle body and axle through a universal transmission device to ensure continuous power transmission.

Buffer and vibration reduction: Absorb road impact and engine torsional vibration, improve ride comfort and extend component life.
