VISCOMATIC (TRADE NAME): A THIRD GENERATION FOUR-WHEEL-DRIVE SYSTEM

The external controllability of a viscous coupling was investigated. Simultaneously with the rig tests, a test vehicle was prepared, which included the development of a control logic for the microprocessor control system. The concept of the Viscomatic being a combination of a planetary gear and a viscous coupling with a stationary external housing was the main objective of the tests. With a manually adjustible viscous coupling, the driving behavior of the test vehicle may be varied within a wide range. With automatic control, the vehicle reaction is always clearly defined and easy to handle.
