Abstract: A universal joint has a balancing arrangement that includes yoke arms having respectively, a support bore, centered on a common bore axis, and the support bore having a groove. A journal cross assembly comprises four journals, which axes intersect each other perpendicularly, and bearing bushings, having, respectively, a bottom, having an outer face, and in which bearing bushings, a journal is, respectively, supported. Respectively, one bearing bushing is received in a support bore and is secured by means of a retaining ring, engaging in the groove and supported on the outer face of the bottom of the corresponding bearing bushing. The retaining ring has a support portion on which radially inwards and projecting towards the bore axis, a holding portion is attached, axially offset to the support portion and distanced to the bottom, forming a gap. A balancing weight, formed as a ring discontinued at a point, can be retained in the gap between the bottom and the at least one holding portion.

Abstract: A joint yoke for a universal joint, as well as to a universal joint having the same. In such a universal joint, the two joke arms in the joint yoke are separated into a base portion having integrally arm portions and bridge elements. For attaching the bridge elements, headed screws are used, for which in the end faces of the arm portions threaded bores are arranged. The threaded bore which, when projected onto the bore axis 10 of the neighboring support bore, has the largest distance from the longitudinal axis 5 has a diameter remarkably increased compared to the other threaded bores 19, 20. Compared to embodiments in which several headed screws and corresponding threaded bores are provided, which have the same diameter, an above proportional increase of the torque transmission can be achieved.

Abstract: A cross member unit for universal joints has a cross member (6) with four trunnions (17). Each two trunnions define a common longitudinal axis (7). Each trunnion (17) has an end face (18), a first sealing face (21) and a pre-sealing face (24). The pre-sealing face (24) is remote from the end face 18 and has a diameter increasing relative to the first sealing face (18). A bearing bush (9) is on each trunnion (17). Each bearing bush (9) has an open end 29 and has rolling contact members 27 rotatably supporting the trunnion (17) around the longitudinal axis (7) of the trunnion (17). An annular seal (30) is provided in each bearing bush 9. The annular seal (30) is held in the bearing bush 9 by a press fit. The annular seal (30) includes an annular carrier (31) which projects from the open end (29) of the bearing bush (9). The annular seal includes at least one first sealing lip (35) which is in contact with the first sealing face (18) of the trunnion (17).

Abstract: An intermediate bearing for a driveline of a commercial vehicle has a housing (7) with a stirrup-shaped cross-section. The housing (7) has a fixing face (12) formed of two straight portions (8, 9) and a first arched portion (10). A bearing member (15) is arranged between the portions (8, 9, 10). The bearing member (15) is rubber and is connected to the fixing face (12) by vulcanization. A locking element (23) bridges the space between the two straight portions (8, 9). The locking member (23) is attached to the bearing member (15). The bearing member (15) encloses a supporting ring (16) which serves to receive a rolling contact bearing. The locking element (23) is adjustable for the purpose of setting a pre-tension of the bearing member (15) towards the longitudinal axis (18) of the bore (17) of the supporting ring (16). The locking element (23) can be connected to the housing (7) after the required pre-tension has been set.

Abstract: The present invention relates to a lubricant for service-free cardan shafts comprising a base selected from the group consisting of a naphthenic solvent and a paraffinic solvent; a thickener selected from the group consisting of lithium salt, lithium soap, and amides of aromatic dicarboxylic acids; at least one flux oil; and an additive selected from the group consisting of molybdenum dithiocarbamate, zinc dithiocarbamate, bismuth dithiocarbamate, molybdenum dithiophosphate, zinc dithiophosphate, and bismuth dithiophosphate, in combination with thiadiazole.

Abstract: A cross member unit (9) has a cross member (10) with four arms (11). Two each are centered on axes (y, z) extending perpendicular relative to one another. The two arms (11) of one axis (y, z) are received in one yoke arm (19) of a joint yoke. Each arm (11) is associated with a bearing bush (13) rotatably supported by rolling contact members (14). A centering element (23), with a pressure element (29) and a spring element (28), are positioned in each arm. The spring element (28) is supported against the arm (11) and loads the bearing bush (13) via the pressure element (29). The bearing bushes (13) associated with one axis (y, z) are received in the two yoke arms (19) of a joint yoke. If the yoke arms (19) are deformed due to rotational-speed-related centrifugal forces, the pressure elements (29) remain in contact with the bearing bushes (13). In this way, the cross member unit (9) is held in a centered way relative to the joint yoke.

Abstract: The invention relates to a universal joint having a first joint yoke (1) and a second joint yoke (8) as well as a cross member (23) for connecting said yokes. In the region of its two second yoke arms (11), the second joint yoke (8) is separated along a line extending through the second bearing bores, so that per yoke arm (11), there are obtained two yoke arm portions (15) continuing to be connected to the base portion (9), and a separate bridge portion (16). Separation takes place in the form of fracture separation, for which purpose regions in the second bearing bores are heat-treated by laser along a line; thereafter, a force applied to and concentrating on said regions leads to fracture faces which correspond to brittle fracture faces, so that after the separating operation, joining can easily take place without the bearing bores subsequently having to be re-machined. In this way, assembly is simplified.

Abstract: A cross member for a universal joint has a base member (1) and four arms (2). The arms (2) extend away from a base member (1). To increase the torque bearing capacity of the cross member, the outer face of the arm (2) (if viewed in a longitudinal section) extends curve-like in a transition region (18) to the base member with a continually increasing diameter and with a decreasing radius of curvature (R). If viewed in a sectional plane extending through the axes (4, 5), a distance (X) exists between a first tangent (14), on the outer face of the transition region, and a second tangent parallel to the first tangent (14). The first tangent (14) extends at an angle of 45 degrees relative to the axis (4). The second tangent (15), if viewed from the center (6), is positioned behind the first tangent (14). The second tangent (15) contacts the outer face of the base member (1) at a point (16) which is located on a line of symmetry (17) of the cross member.
