摘要: A driveshaft (1) for driving the wheels of a motor vehicle has two constant velocity joints (2, 3) and a connecting shaft (4). The two constant velocity joints (2, 3) are provided in the form of constant velocity fixed joints. The plunging assembly required to change the longitudinal distance (L) includes a plunging journal (21), formed onto the second joint part (20) of the second constant velocity joint (3), and a plunging portion (26) of the connecting shaft (4). The shaft (4) surrounds the plunging journal (21) and is provided in the form of a tubular shaft. The cross-section of the plunging portion (26) has the shape of a corrugated shaft. Each outer corrugation peak, in the bore of the plunging portion (26), includes a second running groove (29) positioned opposite a running groove (22) in the plunging journal (21). Balls (23) are rollingly arranged between the two running grooves (29, 22) and held by a cage (24). By providing the plunging portion (26) of the connecting shaft (4) in the form of a corrugated tube, it is possible to use less mass and to increase the strength values as a result of the forming operation. At the same time, the vibration behavior is improved.

摘要: A constant velocity joint (2) with a connecting shaft (4). The inner part (12) of the constant velocity joint (2) includes a through-bore (28) with a first portion in the form of inner teeth (29) and a second bore portion in the form of a circular-cylindrical bore portion (32). A coupling sleeve is inserted into the inner part (12). The coupling sleeve (33) includes outer teeth (34) which engage the inner teeth (29). These are followed by a circular-cylindrical portion (35) centered in the bore portion (32). The coupling sleeve (33), on its inner face, has first longitudinal grooves (37) arranged opposite second longitudinal grooves (39) of the connecting shaft (4). Rolling-contact members (40) are received between the first and second longitudinal grooves and are held so as to be guided in a cage. Members (40) serve to transmit torque between the coupling sleeve (33) and the connecting shaft (4) and enable a linear adjustment between the coupling sleeve (33) and the connecting shaft (4). By separating the inner part (12) from the coupling sleeve (33), production of the inner part is improved and it is possible to divide the joint function into a plunging movement and angular movement.

摘要: A method of producing a metal sleeve having at least one recess open at thend face extending over a portion of the axial length of the sleeve from a cylindrical pipe section comprising (a) inserting a cylindrical pipe section into the annular cavity of a die which cavity is radially greater than the wall thickness of the pipe section, (b) subjecting the pipe section to axial ram pressure whereby a bulge in the central portion of the pipe section occurs with the central portion bearing against the outer limiting wall of the die cavity and the end portions bearing against the inner limiting wall of the die cavity, (c) applying further pressure on the pipe section whereby it fills the die cavity except for a circular depression in the center of the pipe section bore and (d) acting on the resulting pipe section with a second ram with an end face with contours corresponding to the recesses whereby the displaced material from the contours enter into the circular depression of the pipe section to partially fill the same.
