Focus 2 Automatic transmission Tripoid Internal
Purpose:
* Transmission of torque from the differential to the wheel with a displacement of the axis of rotation.
* Allows the wheel to move at an angle to the longitudinal axis of the car.
Design:
* Shaft with three spherical rollers installed in a cage.
*Socket connected to differential.
* Spline connection for connection to the wheel hub.
Working principle:
* The tripoid shaft rotates in the cage, and the rollers roll along its inner surface.
* The rollers are held in the cage by a guide plate.
* When the wheel turns, the rollers move in the cage, allowing the tripod shaft to move at an angle to the wheel’s axis of rotation.
Advantages:
* High reliability and durability.
* Ability to transmit high torques.
* Ability to work at large rotation angles.
Malfunctions:
* Worn rollers or guide plate.
* Deformation of the holder or shaft.
* Damage to the spline connection.
Symptoms of malfunction:
* Noise or vibration when cornering.
* Deterioration in vehicle handling.
* Lubricant leaking from the tripod boot.
Replacement:
*To replace the internal tripod, the axle shaft must be removed from the vehicle.
* Press the old tripod out of the socket and press in the new one.
* Check the spline connection and replace the wheel hub if necessary.
* Install the axle shaft into the car.
* Fill the tripoid boot with lubricant and install it in place.
Note:
* The internal tripoid on the Focus 2 automatic transmission has a right-hand thread, and the external tripoid has a left-hand thread.
* When replacing a tripoid, it is extremely important to use a high-quality lubricant designed for tripoid joints.
