Haldex Coupling The development of the Haldex coupling is a Characteristics of the Haldex coupling giant step forward in modern all wheel drive technology. The Haldex coupling is control Permanent all wheel drive with electroni lable, based on the inputs the Haldex control cally controlled multi plate clutch module receives from the vehicle. Front drive characteristic Quick response Slip is no longer the only decisive factor in No strain on clutch when parking and the distribution of drive forces; the car s maneuvering vehicle dynamic state is also a factor. The Haldex Compatible with different tires e.g. control module monitors the ABS wheel emergency wheel speed sensors and the engine control mod No restrictions on towing with the rear ule accelerator pedal signal via the CAN axle on the ground bus. This data provides the control module Fully combinable with systems such as with all the information it needs on road the anti lock brake system ABS , the speed, cornering, coasting or traction mode, electronic differential lock EDL , the anti and can respond optimally to any driving sit slip regulation ASR , the electronic brake uation. distribution system EBD and electronic stabilization program ESP Haldex Coupling 12 Haldex Coupling The Haldex coupling is mounted on the rear axle differential and is driven by the prop shaft. Engine torque is transmitted to the prop Rear Differential shaft through the gearbox, the front axle dif ferential and the front axle drive. Haldex Coupling The prop shaft is connected to the input shaft of the Haldex coupling. In the Haldex coupling, the input shaft is separated from the output shaft to the rear axle differential. Torque can only be transmitted to the rear axle differential when the Haldex coupling Prop Shaft clutch plates are engaged.
