Haldex coupling pump BAPMIC BF0319680012 (4th generation)

Description:

The Haldex coupling pump BAPMIC BF0319680012 (4th generation) is an electric pump that is used in all-wheel drive (4WD) systems of many modern vehicles. It is a key component that provides the hydraulic pressure required to activate the Haldex clutch and transfer torque from the transmission to the rear seat.

The axle is driven by the Haldex coupling:

1. ABS and ESP sensors continuously monitor wheel speed, wheel speed and other vehicle steering parameters.
2. The control unit analyzes data from the sensors, which means the amount of torque required to be transmitted to the rear seat.
3. The electric motor of the pump is activated by the control unit.
4. The vicor pump creates a hydraulic drive for the vise, which is then directed to the hydraulic cylinder.
5. The hydraulic accumulator saves pressure when the pump is not running, ensuring the hydraulic response when required.
6. The hydraulic pressure from the pump is directed to the hydraulic cylinder, which activates the Haldex clutch.
7. The clutch connects the transmission to the rear axle, transmitting torque.

Important: when servicing the Haldex coupling pump, follow the manufacturer's recommendations for components and service intervals. It is also necessary to contact a qualified auto mechanic for diagnosis and repair.
