SHIFT-BY-WIRE GEARSHIFT MECHANISM COMPRISING A P POSITION

WIPO Patent Application WO2004089677

A3

The invention relates to gearshift mechanism for transmitting, without force, gearshift commands to an automatic transmission of a motor vehicle. Said gearshift mechanism comprises a housing and a gearshift lever (1) pivotally mounted in a shift gate. The gearshift mechanism has a first and a second shift stop (7, 15; 9, 16) for the gearshift lever (1), which stop consists of a stop (7, 9) on the housing end and a stop (15, 16) on the gear-shift lever end. The gearshift mechanism further comprises a detection device for these two gearshift positions (12, 13). A restoring force automatically swings the gearshift lever (1) from a deflected gearshift position (12, 13) into a rest position (11) between these two gearshift positions (12, 13). The invention is characterized in that the stop (15), associated with the gearshift position (12) and mounted on the gearshift lever end, is linked with an actuation device (3, 4) on the gearshift lever (1). When the gearshift lever is actuated, the stop (15) is displaced and the gearshift lever (1) can be guided beyond this gearshift position (12) to an additional stop (8, 17).
