How to Test If the Car Clutch Plate Is Slipping?

There is a simple and effective way to determine whether the car clutch plate is slipping

Start the engine, put it in gear, pull the handbrake, slowly lift the clutch plate until it is fully disengaged. If the vehicle immediately stalls, it proves that there is no slipping problem with the clutch plate, otherwise it indicates that there is slipping.

The following situations can indicate the clutch plate slipping:

  • The vehicle cannot reach its maximum speed under standard conditions. For example, when the engine speed is 2200 rpm in fifth gear, the corresponding speed is 90 km/h. After the clutch plate starts slipping, the speed may be lower than before.

  • When the vehicle accelerates quickly, the engine speed increases rapidly, but the speed of the vehicle does not increase as quickly, and the acceleration decreases.

  • When driving on a long uphill road, the vehicle will emit an obvious odor.

  • When starting the vehicle, the clutch plate needs to be lifted high.

  • Recently, the vehicle has been consuming more fuel, which may be a sign of the clutch plate slipping.

It should be noted that we should try to reduce the time and frequency of half-clutching when driving, otherwise it will cause serious wear and tear on the clutch plate.


It is recommended to go to a professional repair shop for inspection, and carry out corresponding checks or repairs according to the situation. If it is serious, it should be replaced in time to ensure driving safety.

Working principle and structure of car clutch plate

The clutch is a component directly connected to the engine in the automobile transmission system. It is responsible for cutting off and connecting the power and transmission system, so it can ensure smooth start-up when the car starts, and also ensure smooth shifting and prevents overload of the transmission system.

The clutch is a transmission mechanism with active and driven parts. The two parts can be temporarily separated or gradually combined, and relative rotation may occur during the transmission process. Therefore, the active and driven parts of the clutch rely on contact friction to transmit torque, or use the pressure force required by friction, or use liquid as the medium for transmission, or use magnetic force transmission to transmit torque.

The friction clutch tightened by springs is widely used in automobiles at present. When driving a car, the power transmission must be maintained regularly, while interrupting the power is only temporary. Therefore, the active and driven parts remain in a combined state for a long time while driving. When the driver steps on the clutch plate pedal, the driven parts and the active parts are separated through the transmission mechanism.

Depending on the number of driven discs, friction clutches can be divided into single-disc clutches and double-disc clutches. Single-disc clutches are mainly used in cars and light trucks, while double-disc clutches have a larger torque transmission, so they are mainly used in medium and heavy-duty trucks. Depending on the structure of the pressure spring, friction clutches can be divided into spiral spring clutches and diaphragm spring clutches.
