Why Step on the Clutch When Braking?
1 Answers
When braking, there is no need to step on the clutch first. Utilize engine braking to fully decelerate, and then press the clutch at low speeds to prevent the engine from stalling. The functions of the car clutch: 1. Ensure smooth starting: Before starting, the car is stationary. If the engine and transmission are rigidly connected, once a gear is engaged, the car will suddenly lurch forward due to the abrupt connection of power. This not only causes damage to mechanical components but also makes the driving force insufficient to overcome the huge inertia generated by the sudden forward movement, leading to a rapid drop in engine speed and stalling. 2. Facilitate gear shifting: During driving, different transmission gears are frequently used to adapt to changing driving conditions. Without the clutch temporarily disconnecting the engine from the transmission, the meshed force-transmitting gears in the transmission would be difficult to separate due to the high pressure between their meshing surfaces caused by the unrelieved load. 3. Prevent overload in the transmission system: During emergency braking, the wheels suddenly decelerate sharply, while the transmission system connected to the engine maintains its original speed due to rotational inertia. This often generates an inertial torque in the transmission system far greater than the engine torque, making the transmission components prone to damage.
