Patent number: 7322457Abstract: A shifting device (1) for the mechanical coupling-free transmission of shift commands to an automatic transmission of a motor vehicle (shift-by-wire shifting), with at least one housing and/or one frame and one selector lever for the manual selection of shift commands for the vehicle transmission in at least one shift gate. The selector lever can be moved manually into at least four positions (P, R, N, D), pivotable about at least one shift axis. A transmission device(s) transmits the shift commands without mechanical coupling with the vehicle transmission (shift by wire). A mechanical coupling (16) is provided between the selector lever (2) and the transmission of the vehicle. This mechanical coupling (16) activates the parking brake exclusively and automatically when the selector lever (2) is engaged in the P position and is automatically uncoupled from the selector lever when the selector lever (2) is pivoted out beyond the adjacent position.Type: GrantFiled: June 21, 2005Date of Patent: January 29, 2008Assignee: ZF Lemförder MetallWaren AGInventors: Andreas Giefer, Jörg Meyer

Patent number: 6631655Abstract: The invention relates to a shifter for actuating at least one gear mechanism of a bicycle including a housing, a gripping element for actuating the shifter, and a movable element for exerting tension on and/or for releasing a gear transfer means. The movable element has a pawl which engages in a set of latching teeth in the housing. The gripping element has a lifter which disengages the pawl from the latching teeth during a shifting operation in the release direction. A driver on the gripping part preloads a spring on the movable element during a shifting operation in the release direction which urges the movable element in the release direction. The advantage of a shifter for bicycle gear mechanisms according to the present invention is to be found in that, by simple means, it becomes possible to shift gears, especially in the release direction, quickly and independently of the preload being exerted on the movable element by the gear mechanism via the transfer element.Type: GrantFiled: February 16, 2001Date of Patent: October 14, 2003Assignee: SRAM Deutschland GmbHInventors: Georg Blaschke, Marcus Auer
