Design of the 4th generation Haldex clutch

Design of the 4th generation Haldex clutch

Item Description
1 Fluid filter
2 All-wheel drive control unit
3 Electric feed pump
4 Pressure accumulator

The electric feed pump is an axial piston pump which is more robustly designed than the gerotor pump in the 3rd generation Haldex. The higher feed pressure means that the ring piston pump at the clutch plate assembly, the pressure relief valves, preload valve and the high pressure valves are no longer necessary.

The pressure accumulator on the 4th generation Haldex is larger and is designed for the higher pressure.

The 4th generation Haldex has a larger fluid filter which contains a non-return valve.

The all-wheel drive control unit no longer contains a pressure sensor in the 4th generation Haldex.
