Abstract
A constant velocity fixed joint comprising an outer joint part forming an annular member with a first longitudinal axis and comprising first ball tracks. The first ball tracks extend at a distance from the first longitudinal axis and each form a first angle of crossing therewith. The joint also includes an inner joint part forms a hub with a second longitudinal axis and comprising second ball tracks. The second ball tracks extend at a distance from the second longitudinal axis and each form a second angle of crossing therewith. The first ball tracks and the second ball tracks are circurnferentially distributed and associated with one another in pairs, with the first angles of crossing and the second angles of crossing of the pairs of ball tracks being identical in size and opening in opposite directions relative to the longitudinal axes. When the longitudinal axes coincide, the points of intersection of the pairs of ball tracks form a central joint plane. The joint also includes an annular ball cage arranged between the outer joint part and the inner joint part and comprising circumferentially distributed cage windows in which torque transmitting balls are held in a common plane.
