Form closure coupling device i.e. gear box coupling device, for drive train of motor car, has catch teeth including capture regions, where width of each catch tooth in capture regions is smaller than middle width of each clutch tooth

摘要

The device has a coupling part (10a) including a claw gearing (12a) with catch teeth (15a, 16a) and clutch teeth (18a, 19a) for torque-proof connection in a switching position. The catch teeth include capture regions (21a, 22a), where a width of each catch tooth in the capture regions is smaller than a middle width of each clutch tooth. The catch teeth include tooth flanks (27a, 28a) with a clutch edge region and a catch edge region arranged in a common plane or two different planes. The catch teeth include hook regions in a stepless transition between the capture regions.
