A spider, for a universal joint for prop shafts suitable for the transmission of torque, comprising pins arranged around a mid-point and extending from the base body in pairs about a common axis, whereby the axes cross at the center of the spider at a right angle. Each pin comprises a surface arranged concentrically about the corresponding pin axis forming a running surface, or has a running surface for the rollers of a roller bearing and a transition region between the surface forming, or supporting a running surface and the base body. The spider is characterized by the following features:—functional surfaces for the support of at least one sealing device with formation of a seal surface of a sealing pair on the front face of the base body facing the pin, on each pin, said functional surface runs perpendicular to a plane which runs from the pin axis of the corresponding pin to an adjacent pin in the circumferential direction, the functional surface runs from the transition region to at least a region in the radial direction about the pin axis which may be described by a radius which corresponds to at least 1.5 times the radius of the pin and each functional surface is provided with at least one centering surface perpendicular thereto for the bearing mounting of a seal holder supporting the sealing device.

A thrust ring, in particular an axial bearing thrust ring, for forming a running surface for rolling elements, for use in bearing systems for universal joints of cardan shafts. The ring has a first planar end side and a second end side, having two surface regions on the second end side which have been machined symmetrically with respect to a first axis of symmetry SD of the thrust ring, and also in terms of its profile in the circumferential direction as seen starting from the first axis of symmetry, in the circumferential direction, to a further, second axis of symmetry SSD which runs at right angles to the first axis of symmetry SD. Each of the surface regions can be described by a change in cross section of the thrust ring, which change comprises a reduction in the thickness dimensions describing the cross-sectional area in the region of the inner circumference and the outer circumference of the thrust ring, wherein the reduction in the thickness dimensions in the region of the inner circumference being less than in the region of the outer circumference.

A flange yoke for a universal joint, two joint fork halves, each comprising a base component and a bearing component. The joint fork halves can be connected in a form-locking manner to one another in the region of their base component to form a flange. The base components have mutually complementary toothing in the region of the outer circumference on their coupling face, wherein the extension of a tooth trace of the toothing on the coupling face forms an angle of from >0 degrees to

A universal joint apparatus having jointed shaft suited for transmitting high torques, comprising a spider and two yokes for fitting the arms of the spider. Each spider arm is fitted, with a bearing setup having a radial bearing with an outer ring and an inner ring, an axial bearing arranged in the area of the spider arm wrist, in a yoke eye associated with the latter. The axial bearing is disposed in a connecting structure of elastic behavior.

A shafting, particularly a cardan shaft for rail vehicles, has two cardan joints (4,5), each of which comprises two link forks (7–10) coupled to one another by a central part (6). The central part (6) comprises at least two partial elements (38.1,38.2) that are connected to one another in the peripheral direction in a rotationally fixed manner by a shaft-hub connection, and in a displaceable manner in the axial direction. The shafting further includes a rotary actuator (17) arranged in the central part for performing a torsional movement of the corresponding end areas of one of the two partial elements of the central part relative to one another.

The invention relates to a yoke (4) which is used in universal-joint propeller shafts, having at least one leg member (7) which is connected to an input or output part of a machine element comprising at least one bearing part (8) surrounding a bore (9). Said bore (9) forms a supporting surface (10) at least one partial zone of a roller-bearing arrangement (11) for the positioning of a journal (6) of a differential-pinion shaft (3). The invention is characterized in that the supporting surface has at least one local recess (20) in the region of the rolling elements (14)) of the roller-bearing arrangement (11) which is subjected to maximum tensile stress during the transmission of the torque.
