Top Causes of Accumulator Malfunction and How to Prevent Them

The failure of accumulators (usually referred to as “clutches” in the automotive industry) can be caused by various reasons. The following are the main causes of common failures and corresponding preventive measures:
Common fault causes
Excessive wear of clutch plates:
Reason: The clutch plate is worn out due to prolonged use or improper operation.
Consequence: The engine power cannot be fully transmitted to the gearbox, resulting in insufficient vehicle power.
Improper adjustment of clutch pedal free stroke:
Reason: The free travel is too large or too small.
Consequence: Affects the engagement effect of the clutch plate, resulting in the clutch not being able to tightly engage.
Pressure plate and diaphragm spring issues:
Reason: The pressure plate is fixed on the flywheel of the engine, and the diaphragm spring is responsible for compressing the clutch plate. If the elasticity of the diaphragm spring weakens, it will affect the tight fit of the clutch plate.
Consequence: The clutch cannot be tightly engaged, and power transmission is affected.
Improper use:
Reason: The driver did not fully press the clutch pedal when shifting gears, or used the semi linkage technique for a long time when starting.
Consequence: Accumulator the wear of clutch plates and shorten the lifespan of the clutch.
Other faults:
The separation bearing or clutch pedal control mechanism has malfunctioned, causing the clutch to be unable to fully separate or engage.
preventive measure
Pay attention to car maintenance:
Carry out careful maintenance according to the manufacturer’s regulations, such as tightening the connectors and lubricating the lubrication parts.
Add protective agents (additives) to lubrication and cooling systems to reduce wear and corrosion.
Timely elimination of hidden faults:
Regularly check the working status of the clutch, and promptly adjust or repair any abnormalities found.
Regularly replace clutch discs and other vulnerable parts to ensure the normal operation of the clutch.
Correct operation and use:
The driver should ensure that the clutch pedal is pressed all the way when shifting gears to avoid excessive wear of the clutch plates.
Manual transmission cars should use semi linkage techniques reasonably when starting, and control the semi linkage time to avoid being in a semi linkage state for a long time.
Enhance safety awareness:
Car owners should strengthen their awareness of car safety, maintain and repair their cars in a timely manner, and avoid improper usage behaviors such as overloading and speeding.
By taking the above preventive measures, the occurrence of faults in the accumulator (clutch) can be effectively reduced, ensuring the safety and normal operation of the vehicle.
