Ford automatic transmission friction discs
Purpose:
Friction discs are an integral part of automatic transmissions (automatic transmissions) of Ford vehicles. They transmit torque between various transmission components such as drive gears and drums.
Design:
Friction discs are usually made of a special material called friction. This material has a high coefficient of friction, which allows the discs to adhere to metal surfaces. The discs are ring-shaped with grooves or splines on the inner and outer surfaces.
Types:
Ford automatic transmissions use several types of friction discs, including:
* Steel: Made from durable steel and contains no friction material. They are used to transmit torque between metal surfaces.
* With friction lining: Consists of a steel carrier onto which a layer of friction material is glued. These discs transmit torque between the steel and drum surfaces.
* With composite lining: They have a friction material that is reinforced with fibers. These discs provide smoother shifting and reduced wear.
Location:
Friction discs are stacked inside the automatic transmission. Each stack consists of alternating steel and friction discs. When the solenoid applies oil pressure to the stack, the friction discs are pressed against each other, transmitting torque.
Replacement:
Friction discs wear out over time, especially if the transmission is not properly maintained. Symptoms of worn friction discs include:
* Gear slippage
* Delays when shifting gears
* Grinding or humming sound when shifting gears
It is important to regularly service your automatic transmission and replace friction discs when necessary to ensure smooth and reliable operation of the transmission.
