Differential Assembly: Description and Operation

OPERATION





A gerotor pump (1) creates oil flow through the filter (4) whenever left and right wheels spin at different speeds and the solenoid valve is activated. The oil flow is restricted by a Pressure Regulating Valve (PRV) to build oil pressure. Pressurized oil is then fed to a piston (2) chamber. The piston compresses the clutch pack (3) providing additional torque to the lower speed wheel.

When the antilock brakes are activated the differential solenoid is switched off and pressure is bleed off the clutch pack.
