the crown wheel differential 1 is installed a centrifugal force acts on the differential wheel 4 a as a result of rotation about the axis of rotation 2 by virtue of this centrifugal force the lower disc shaped stop structure 10 a bears on the crown wheel 5 a whereas the top disc shaped stop structure 9 a has play in relation to the crown wheel 5 a fig7 shows as a detail a crown wheel differential in which a pinion shaft 260 has a gearwheel 262 with two disc shaped stop structures 209 120 the gearwheel 262 together with a crown wheel 205 connected fixedly to a casing 203 of the crown wheel differential forms a drive toothing 261 the two disc shaped stop structures 209 210 are formed as integral parts of the gearwheel 262 the use of the gearwheel pairing for a differential is not restricted to crown wheel differentials for rear axle transmissions thus differentials for front axle transmissions and longitudinal differentials may also be envisaged to act as a stop the stop structure does not necessarily have to be rotationally fixed with respect to the toothing of the differential wheel thus to make it easier to machine the spur toothing of the differential wheel for example a disc may be provided which is arranged fixedly in terms of rotation or rotatably on a basic gear body in this case discs may be disposed at opposite sides.
