Abstract
A driveshaft (11) having two ball type constant velocity fixed joints (12, 13), a shaft part (14) connecting said two joints, and an axial plunging part (15) arranged in said shaft part (14). The ball type constant velocity fixed joints (12, 13) each comprise: a bell-shaped outer joint part (16, 26) provided with internally positioned first ball tracks (18, 28); a hub-shaped inner joint part (19, 29) provided with externally positioned second ball tracks (21, 31) and arranged inside said outer joint part (16, 26); balls (24, 34) engaging pairs of first ball tracks (18, 28) and second ball tracks (21, 31); and an annular ball cage (22, 32) with circumferentially distributed cage windows in which the balls are held in a common plane. The pairs of first ball tracks (18, 28) and second ball tracks (21, 31), when viewed in a longitudinal section, form opening angles (&agr;12, &agr;13) relative to one another for controlling the balls (24, 34) in the ball tracks. The opening angles (&agr;12, &agr;13) of the pairs of first ball tracks and second ball tracks at both ball type constant velocity fixed joints (12, 13) open in the same direction.
