Constant velocity fixed joint with cross-groove tracks

A constant velocity fixed joint comprising:

• an outer joint part (11) forming an annular member with a first longitudinal axis and comprising first ball tracks (12), wherein the first ball tracks (12) extend at a distance from the first longitudinal axis and each form a first angle of crossing (α1, α1′) therewith;
• an inner joint part (13) forming a hub with a second longitudinal axis and comprising second ball tracks (14), wherein the second ball tracks (14) extend at a distance from the second longitudinal axis and each form a second angle of crossing (α2, α2′) therewith, wherein the first ball tracks (12) and the second ball tracks (14) are circumferentially distributed and associated with one another in pairs, with the angles of crossing (α1/α2, α1′/α2′) associated with the individual pairs of ball tracks (121/141, 122/142) being identical in size and opening in opposite directions relative to the first and second longitudinal axes, and wherein when the first and second longitudinal axes coincide, the points of intersection of the pairs of ball tracks (12, 14) form a central joint plane;
• and
• an annular ball cage (17) arranged between the outer joint part (11) and the inner joint part (13) and comprising circumferentially distributed cage windows (16) in which torque transmitting balls (15) are held in a common plane;
• wherein the outer joint part (11) comprises two separate circumferential areas which are positioned on either side of the central joint plane and which are interrupted by the first ball tracks (12), said areas comprising inner guiding faces (25) which are simultaneously in guiding contact with an outer counter face (19) of the ball cage (17).
