Abstract
The invention relates to a constant velocity fixed joint and to the introduction of the cage into the outer joint part of a constant velocity fixed joint. The joint comprises an outer joint part, an inner joint part, a ball cage and balls. The outer joint part forms a bell-shaped member comprising a first longitudinal axis, a base, an aperture and circumferentially alternating first and second outer ball tracks. The inner joint part forms a hub comprising a second longitudinal axis and circumferentially alternating first and second inner ball tracks. The first outer and first inner ball tracks, together form first track pairs and the second outer and second inner ball tracks, together, form second track pairs. Each track pair accommodates a torque transmitting ball, with the tangents at the balls in the points of contact with the track pairs forming control angles. The first track pairs form control angles which open towards the aperture in the outer joint part and the second track pairs form control angles which open towards the base of the outer joint part. The outer joint part comprises a substantially internally spherical guiding face which is widened by two recesses which start from the joint aperture and extend into the joint interior.
