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 (alpha12, alpha13) relative to one another for controlling the balls (24, 34) in the ball tracks. The opening angles (alpha12, alpha13) 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.
