Centrifugal regulator automatic transmission A140L
The centrifugal governor in the A140L automatic transmission is an important part of the torque converter, which is used to control the transmission ratio.
Operating principle
The centrifugal regulator consists of two main parts:
* Weights: Heavy metal weights attached to the rotating hub.
*Springs: Springs that keep weights from rotating.
When the rotation speed of the torque converter increases, the centrifugal force acting on the weights overcomes the force of the springs, and the weights begin to rotate outward. This movement of the weights causes axial movement of the governor hub.
Function
The centrifugal regulator performs the following functions:
* Torque Converter Fluid Volume Control: As torque converter speed increases, the governor weights rotate outward, increasing hub axial movement and decreasing torque converter fluid volume.
*Changing Transmission Ratio: Reducing fluid volume results in less torque being transferred from the engine to the transmission, which in turn causes the transmission to shift into a higher gear.
* Torque Converter Anti-Slip: Centrifugal governor helps prevent torque converter slip at high speeds by reducing fluid volume and limiting torque transfer.

Service
The A140L automatic transmission centrifugal governor usually does not require regular maintenance. However, it may need to be checked or replaced in the following cases:
*Transmission Slippage: Worn or faulty adjusters can cause transmission slippage due to improper fluid volume control.
* Difficulty shifting: Faulty adjusters can prevent smooth shifting.
* Abnormal Noise: Worn or faulty regulators may make abnormal noise when operating.
