Constant velocity ball joint with ball pairs whose tracks are located on symmetrical planes

摘要

A constant velocity fixed ball joint provided with an outer joint with outer tracks and an inner joint part with inner tracks. The outer tracks and inner tracks form sets of tracks, with a torque transmitting ball being guided in each set of tracks. A ball cage accommodates the balls in circumferentially distributed cage windows and, when the joint is articulated, guides the balls on to the angle-bisecting plane between the longitudinal axes. The cage windows each accommodate pairs of balls. When the joint is in the aligned condition, in the central joint plane, the angular distance of the balls within the individual pairs of balls is smaller than the angular distance between balls associated with pairs adjoining one another; and the center lines of the sets of tracks of the pairs of balls extend in planes which extend parallel relative to one another.
