Abstract
A constant velocity fixed joint has an outer part an inner part a cage and balls which are guided by the cage in the outer running grooves of the outer part and in the inner running grooves of the inner part The inner part is held relative to the outer part entirely by the balls in the radial direction and by the ball on the one hand and by a control element on the other hand, which control element is supported on the inner part and on a supporting element associated with the outer part Beyond the advantageous supporting conditions achieved by said assembly, it is possible to achieve a further reduction in friction by friction-reducing means which are provided in the form of lubricating grooves for example, thus achieving hydro-dynamic lubrication conditions which are advantageously affected in that the control element achieves high sliding speeds relative to the supporting element
