Friction discs automatic transmission Toyota Corolla
Friction discs are the main components of the Toyota Corolla automatic transmission. They transmit torque from one transmission element to another.
Location
Friction discs are located inside the automatic transmission and are located between the steel drive and driven discs. They are located in a set called a clutch pack.
Design
Friction discs consist of:
* Bases: This is the metal ring that connects the disc to the transmission.
* Friction Material: This is a paper or plastic-like material that covers the base and provides friction.
* Adhesive: Adhesive holds the friction material in place.
Types of friction discs
There are two main types of friction discs used in Toyota Corolla automatic transmissions:
* Friction Material Discs: These discs are made of metal fibers that are sintered together. They provide a high coefficient of friction and a long service life.
*Organic Friction Material Discs: These discs are made from organic materials such as paper or plastic. They provide smoother gear shifting but have a shorter service life.
Functions
Friction discs perform the following functions:
* Torque transmission: They are clamped between the drive and driven disks, transmitting torque from one element to another.
* Inertia: They provide the inertia needed for smooth gear changes.
*Damping: They absorb vibration and shock for a smoother drivetrain.
Replacement
Friction discs are usually replaced during a major overhaul of an automatic transmission. If these drives fail, they can cause:
* Jerks when changing gears
*Transmission slippage
* Increased noise and vibration
To ensure optimal operation of the automatic transmission, it is recommended to use original or high-quality analogues of friction discs.
