Automatic transmission clutches Nissan Cefiro
Purpose
Automatic transmission clutches are special discs that are used in an automatic transmission to transmit torque between various elements, such as shafts, gears and planetary gears.
Design
Nissan Cefiro automatic transmission clutches consist of two main parts:
* Friction Pad: Made from a high friction material such as carbon compound or Kevlar. It provides adhesion between metal surfaces.
* Steel plate: Serves as a base for the friction lining. It provides structural strength and dissipates heat.
Types of clutches
There are several types of automatic transmission clutches in Nissan Cefiro, including:
*Single-directional: Coupling occurs in one direction only, as used in band brakes and overrunning clutches.
*Bidirectional: Coupling occurs in both directions, which is used in clutches.
*Multi-plate: Uses stacks of alternating steel plates and friction linings to increase the torque transmitted.
Location
The Nissan Cefiro automatic transmission clutches are located in various clutch packages inside the gearbox. These packages are activated hydraulically using electronic solenoids.
Malfunctions
Common problems associated with Nissan Cefiro automatic transmission clutches include:
* Wear: Clutches gradually wear out over time, leading to a decrease in the coefficient of friction and slipping.
* Contamination: Contamination of the gearbox can cause friction dust to accumulate, which reduces traction and causes damage.
*Overheating: Extreme temperatures can cause clutches to burn and become brittle.
Diagnostics and repair
Diagnosing faults with Nissan Cefiro automatic transmission clutches usually includes checking the transmission fluid, diagnosing fault codes and mechanical inspection. Repairs may include replacing worn or damaged clutches, cleaning the transmission system, and replacing transmission fluid.
