Know the Working Principle of Motor Clutch and its Damage Symptoms

By -

When talking about big motors (moge) or manual motors, we are no stranger to the term "clutch". The clutch is the main component in the vehicle that has the function of disconnecting and connecting the rotation of the engine and transmission.

Actually, when we pull the clutch lever, we cut off the flow of energy between the engine and the transmission. This causes the transmission to not rotate even if the engine rotates at any speed. At this moment the driver can move the teeth easily and smoothly.

How does the working principle of the clutch?

The clutch works on the principle of friction. The clutch consists of 2 plate components, namely the clutch plate (friction plate) and the clutch plate, the two plates are installed opposite each other.

The clutch cam is connected to the clutch housing, and the clutch housing is connected to the crankshaft. While the clutch plate is connected to the center gear which continues the rotation towards the transmission. Clutch pads and clutch plates are installed in quantities that are adjusted to the needs of the machine, in order to ensure that the grip style in both types of plates is able to support the torque from the machine and transmit energy to the transmission.

When the clutch lever is pulled, the pressure plate will stretch so that the coping plate and the clutch pad will not pinch each other. When this happens, the flow of energy from the engine to the transmission will be interrupted. When the clutch lever is released, the clutch spring will push the pressure plate so that the clutch plate and the clutch pad will rub against each other, the machine is connected to the transmission so that the transmission can rotate because it gets the energy flow from the machine. The pressure plate can stretch and press due to the control system on a clutch that consists of a clutch lever, a clutch cable and a clutch release mechanism.

What are the Symptoms of Clutch Damage?

Because the clutch works on the principle of friction, sooner or later the clutch lining will wear out. Usually the clutch lining is replaced at a mileage of 20,000 km. However, it does not rule out the possibility of replacement being done at a shorter distance interval. This is influenced by driving conditions and terrain.

The symptoms caused by worn out clutch pads are:

  • Slip on the clutch.

This reduction in grip force is due to wear of the brake pads, which can cause abnormal noise in the machine.

  • Engine acceleration is reduced.

The maximum speed of the vehicle will decrease because the energy from the engine cannot be transmitted perfectly to the transmission, due to wear on the clutch lining.

  • Poor clutch performance.

When the clutch pad wears, the flow of energy cannot be cut properly so that the process of gear shifting becomes difficult and the clutch release and pressure mechanism becomes less responsive.

  • Engine revs high.

When the clutch pad wears, the engine rotation becomes higher due to the decreasing acceleration. A higher rpm value is required compared to normal conditions to reach a certain speed.

In addition to driving conditions, another factor that causes clutch damage is bad engine oil conditions. For most vehicles, the wet clutch type (engine oil lubricated clutch) is used, because it has better durability than the dry clutch type. To keep the motor clutch always ideal, it is necessary to carry out routine maintenance. Always change your engine oil when it's service time. Use the Speedwork application to make it easier for you to find the nearest service workshop recommendation.
