Driving device for four-wheel driven motor vehicle, has connector comprising housing, and pressure control valve and sheet membrane reacting during defined high pressure in housing and acting opposite to additional pressure generation

摘要

The driving device (10) has a viscous connector (26) integrated in force flow and transferring torque for an all-wheel drive in a motor vehicle when driving speed difference occurs at an input and an output of the connector. The connector includes a liquid-tight housing, and drive side and output side coupling elements i.e. lamellas, are fixed in the housing. The housing is filled with viscous fluid generated by shearing friction. A pressure control valve and a sheet membrane react during defined high pressure in the housing and acts opposite to additional pressure generation.
