Variable gearbox control system, especially for pre-selecting automatic gearbox range, has intermediate gearbox, second control element for adjustment after failure of first control element

摘要

The arrangement has an intermediate gearbox (HR,PR,SR) for transferring the control movement produced by a first control element (EM) to a selection element (BW) of the adjustable drive. The intermediate gearbox is also connected to a second control element (FS) to enable the gearbox to be at least partly adjusted after a failure of the first control element.
