Assembly having a constant velocity fixed joint and a connecting shaft

An assembly comprising:

• a first constant velocity fixed joint (1) comprising an inner part (5) which is provided with an attaching bore (8);
• and
• a connecting shaft (3) including a plunging unit having a longitudinal axis (12) said plunging unit comprising:
• a plunging journal (15) whose outer face is provided with circumferentially distributed first grooves (16) which extend parallel to the longitudinal axis (12) over the entire length (18) of the plunging journal (15);
• a plunging sleeve portion (11) which comprises a bore (13) which is centered on the longitudinal axis (12) and in which there are arranged second grooves (14) which extend parallel to the longitudinal axis (12), so that one first and one second groove (14, 16) are arranged opposite one another;
• and
• rolling contact members (21) which are rollingly received in the first and second grooves (14, 16) and which are held by a cage (22),
• wherein, the plunging journal (15), by way of part of its length (18) provided with first grooves (16), is received in the attaching bore (8) of the inner part (5) in a rotationally fast way and wherein a length (19) projecting from the inner part (5) and comprising first grooves (16) is dimensioned so as to be longer than an adjustment path 25 resulting from a rolling adjustment in the Plunging sleeve portion (11).
