Abstract: The invention relates to a drive assembly comprising a constant velocity fixed joint 1 with an outer part 4 provided with a flange 7, and a damping element 3 in the form of a ring. The damping element 3 is arranged between the flange 7 and, respectively, the flange-like portion of a cover 19 closing the outer part 4 and the attaching part 20. The damping element 3 includes an aluminum material whose modulus of elasticity greatly deviates from that of the outer part 4, so that any structure-borne sound vibrations originating from the drive end, for example from a drive unit of a motor vehicle, cannot be transmitted from the attaching part 20 into the driveline which includes the constant velocity fixed joint 1. In this way, vehicle comfort is improved.

Abstract: The invention relates to a propeller shaft assembly for connecting the front gearbox output to the drive input of a rear axle drive of a passenger car. Said propeller shaft assembly comprises at least two propeller shaft portions 9, 10. Both are supported by an intermediate bearing 11 arranged in the connecting region. At the gearbox output end, there is provided a first joint 12. In the connecting region between the two propeller shaft portions 9, 10, there is provided a third joint 14. All joints 12, 13, 14 are provided in the form of constant velocity fixed joints. Additionally, towards the ends, there is provided a plunging element 16, 30 which is provided in the form of a rolling contact member guide which rollingly permit displacements along the longitudinal axis 32 and which additionally effect the transmission of torque. This assembly prevents any vibrational excitement either at the gearbox output end or at the axle drive end from reaching the propeller shaft assembly.

Abstract: The invention relates to a telescopic shaft as used, for example, in a connecting shaft between two joints of a driveshaft. The telescopic shaft comprises an outer part (6) and an inner part (12) and a cage (15) arranged therebetween. In the inner face of the outer part (6), there are arranged outer running grooves (10) which extend parallel to the longitudinal axis (5). In the inner part (12) entering the outer part (6) there are provided circumferentially distributed inner running grooves (14). The number of outer running grooves (10) is two or three times the number of inner running groves, so that the outer part (6) comprises more advantageous cross-sectional conditions for hardening operations. Hardness distortions are reduced so that the required functional play values for the opposed outer running grooves (10) and inner running grooves (14) can be accommodated and observed by means of balls (17) guided by a cage (15).

A cage 18 is guided on the inner part 11 and holds balls 21 which, transmit torque between the inner part 11 and the outer part 1 by engaging outer running grooves 5 in the outer part 1 and inner running grooves 14 in the inner part 11. A control element 22 has a spherical contact face 23 which supports the inner part 11 in that the latter is supported on the contact face 23 by means of the control face 17. Furthermore, the control element 22 is supported by a holding face 25 against a supporting face 10 of the supporting element 9 for the purpose of centering the inner part 11 along the longitudinal axis 2 of the outer part on the joint articulation center 0.

Abstract: A constant velocity universal joint has an outer part (1) with outer tracks (3), and an inner part (6) with inner tracks (10) which, together, each receive one of a plurality of balls (13). The ball is guided by a cage (14). The cage is guided on a guiding face (9) of the inner part (6) by a spherical guiding face (16). The outer part (1) is closed towards one side by a first attaching part (5). The other side is closed by a sealing boot (20) which is secured to the outer part (1) on the one hand and to a second attaching element (12) on the other hand.

Abstract: A constant velocity fixed joint has having a hollow outer part (1), an inner part (7) and a cage (15). The parts are centered relative to one another in the radial direction by balls (19) held in the cage (15). A guiding element (22) is adjustably supported in the radial direction against a supporting element (28). The supporting element (22) is fixed relative to the outer part (1). Arrangement and design of the guiding element (22) are such that its contact face (24) forms a plane which contains the articulation center (27). As a result, the setting of the inner part (7) relative to the outer part (1) is advantageously affected in the radial direction. In this way, a low-friction joint is produced.

The inner tracks (16, 17) are worked into the outer face (19) of an outer joint member (11) which carries a flange (12). The outer ball running grooves (30), formed into the outer joint member (11), are arranged opposite inner running grooves (35) of an inner joint member (34). The grooves, together with a cage (36) and guide balls (37), transmit torque. The inner joint member (34) is pivotable around the joint center (42) relative to the outer joint member (11). The central bearing plane (24) is offset from the joint center (42) by a distance sufficient to achieve the smallest possible rolling circle diameter.

A flange is secured to the track portion to connect shaft or gearbox parts. The portion of the outer joint part is produced by cold-forming with an approximately constant wall thickness. The flange includes a central inner recess whose inner contour mates with the outer contour of the track portion. The flange is slid on and connected to the track portion.

Abstract: A coupling (14) axially and non-rotatingly connects two shafts (8, 12). Both shafts, at their ends facing one another, includes shoulders (18, 19) provided with teeth (24). A first tensioning sleeve (29) which, in its bore (28), has a set of teeth (26) matching the teeth (24), is slid onto the two sets of teeth (24) of the shoulders (18, 19), to achieve a non-rotating connection between the two shafts (8, 12). A second tensioning sleeve (30) is threaded onto the outer thread (29) of the first tensioning sleeve (25). The two tensioning sleeves (25, 30) have radially inwardly directed collars (27, 31), which axially contact a contact face (22, 23) of the two shoulders (18, 19). When threaded together, the sleeves cause the two shafts (8, 12) to be axially tensioned so that their end faces (20, 21) are axially tensioned relative to one another.

Abstract: A clamping mechanism (12) connects a tubular shaft (4) to a journal (11). In its bore, the tubular shaft (4) has a profile which is engaged by the journal (11) by a corresponding counter-profile on its outer face along a length of overlap. The profile and counter-profile are tensioned relative to one another by the clamping mechanism (12). The clamping effect is achieved by taking advantage of the possibility of deforming the cross-section of the tube.

Abstract: A constant velocity joint has an outer part (1) with outer running grooves provided in its inner face (2) and extending in meridian planes with reference to the longitudinal axis (4) of the outer part. An inner part (6) is arranged in the inner chamber (5) of the outer part (1). Inner running grooves (13) are arranged in the inner part outer face (10). The inner running grooves (13) are arranged opposite the outer running grooves forming pairs which jointly accommodate balls (31) for torque transmitting purposes. The balls (31) are guided by a cage (24). The inner part (6) includes inner running grooves (13) which are all shortened and are only long enough to provide a maximum travel (18) covered by the balls (31) in the inner running grooves (13) from one extreme position to the other, plus an additional safety length (19) which is provided for strength reasons. A groove portion (14, 15) follows at least one end of the inner running grooves (13).

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).

Abstract: 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).

Abstract: A fixed constant velocity joint has an outer part whose inner face includes outer running grooves. The outer part accommodates an inner part with inner running grooves. Each inner running groove and outer running groove jointly accommodate a torque transmitting ball. A cage is arranged at a distance from the inner face of the outer part. The cage is guided on an outer spherical face of the inner part. The inner part includes a first guiding face which guides a guiding element with a second guiding face. The guiding element is radially displaceably guided and axially supported on a contact face. The functional play of the joint is determined by the diameter of the balls. It is possible to set the play in such a way since there is no contact between the outer face of the cage and the inner face of the outer part.

Abstract: The invention relates to a method of producing a cage for constant velocity universal joints. The method involves a chipless forming operation. The method improves radial guidance of the balls by using larger window faces which are also produced in a chipless way. In a first step, starting from a circular plate metal blank, a dish with a rim is deep-drawn. At the same time, projections are formed which are circumferentially distributed along the inner and/or outer circumference of the dish in accordance with to be produced windows. The projections are directed inwardly and outwardly, respectively, away from the longitudinal axis. Also, starting from the dish opening, the projections extend over a distance which is greater than the width of the to be formed windows. In a second step, the base of the dish and the rim, either simultaneously or successively, are punched out while leaving parts to form the projections at the outer circumference.
