1. A dog clutch arrangement for a motor vehicle comprising:
a clutch body, wherein the clutch body comprises:
first teeth in a first toothing;
an axially movable sliding sleeve arrangement with second teeth in a second toothing,
wherein the sliding sleeve arrangement has a shift ring and a sleeve with the second toothing; and
a shift fork arranged to engage with the shift ring,
wherein the shift ring and the sleeve at least partially overlap in axial direction and are arranged to be axially displaceable relative to one another,
wherein the shift ring and the sleeve enclose an intermediate space, and
a pneumatic damping that damps a movement of the sleeve and the shift ring relative to one another is formed with the intermediate space,
wherein in a disengagement position and an engagement position of the first toothing and the second toothing the intermediate space is minimized and in a tooth-on-tooth position the intermediate space is maximized,
wherein the shift fork is arranged radially in line with the intermediate space.
