part 6 together with the locking means 12 thus the above described counterforce is exerted by means of the rear part 6 to the outer race 11 a wherein the bearing 11 is subjected to a loading between the inner race 11 b and the outer race 11 a caused by the locking thus the cogging 15 can be formed in the sealing element 21 or for example the operations of the spring suspension part 28 and the sealing element 21 can be combined at least partly it is also obvious that the coggings 13 and 14 can also be tilted in the direction of the longitudinal axis x 1 wherein they become conical furthermore it is obvious that the coggings 15 and 16 can also be tilted in the direction of the longitudinal axis x 1 wherein the contact between them can be released when the locking means 12 is moved and wherein they become conical thus also the coggings 15 and 16 are arranged in such a way that they are placed in a contact transmitting the rotational motion at least when the locking means 12 is locked however the forces releasing the locking caused by the profiles of the coggings can thus be increased wherein also the required pressure effect must be greater at the same time the connecting may take more time and the wear of the coggings is increased furthermore the outer race.
