Abstract: A transmission parking lock device having a gearwheel with teeth and gaps and a pawl having a pawl tooth. The gearwheel rotates and the pawl pivots about axes that are parallel to each other. The gearwheel teeth each have a first contour and tooth flanks with respect to rotation of the gearwheel. The pawl tooth has a second contour and tooth flanks relative to the rotation of the gearwheel, and the gearwheel has an outer radius. The gearwheel and pawl are kinematically linked by a linear relationship between the pivoting and rotational angles. The first and/or second contour are at least partially circular with a radius of the outer radius of the gearwheel, and the teeth and/or the pawl tooth have, in the area of the front tooth flank of the gearwheel or parking lock pawl, a crown tip relief relative to the outer radius of the gearwheel.

Abstract: The invention relates to a multi-disk clutch or multi-disk brake (1, 2), comprising an inner disk carrier (4) carrying internal disks (3) and an outer disk carrier (6) carrying external disks (5), friction linings (7, 7?) on the internal and external disks (3, 5), a first end disk (9), on which a closing force for the multi-disk clutch or multi-disk brake can be applied by a piston (10) of a piston-cylinder arrangement which can be actuated by a pressure medium, and a second end disk (8), which forms an axial abutment for the clutch pack (14) formed by the disks (3, 5, 8, 9), wherein the multi-disk clutch or multi-disk brake (1, 2) and/or the components encompassing the clutch or the brake are configured such that the internal and external disks (3, 5) can be wetted with a cooling oil (13). So as to improve heat dissipation during operation, it is provided that the multi-disk clutch or multi-disk brake (1, 2) is configured such that the cooling oil (13) can be directed axially through the clutch pack (14).
