The present invention relates to a sliding cage of universal joint for vehicle, and more particularly, to a sliding cage of universal joint for vehicle for making a shaft joint and a pipe joint smoothly slide as well as operating an elastically contacted needle bearing, installed to the sliding cage, when a universal joint is slipped or delivers rotating torque.

The present invention provides a sliding cage of universal joint for vehicle, comprising: a sleeve; a plurality of mountings positioned to keep distance along the longitudinal direction of the outer side of the sleeve; and a needle bearing and a ball bearing which are installed to the mountings, wherein the sliding cage is provided to the universal joint constructing a steering apparatus for vehicle, thereby being assembled to deliver torque while being slipped toward axial direction.

A universal shaft with a generator for generating electricity with the generator being driven by a cardan error occurring with a rotation of the universal shaft.

A roller bearing for a pod joint comprising an inner race, an outer ring assembly, a race that runs along a bell section and is disposed on the outer surface of the outer ring assembly, a plurality of rolling elements, wherein the plurality of rolling elements are disposed between the inner race and the outer ring assembly and are formed as rollers, and a cage assembly, wherein the rolling elements are disposed in the cage assembly, wherein the cage assembly is formed as a central cage, wherein the rollers pass through the central cage in a middle area, and the running areas thereof project outward from both sides of the central cage.

A cup assembly for a pin of a universal joint bearing includes a cup, a first seal ring attached to the cup, and a second seal ring. The first seal ring includes an elastic element and a spring element configured to preload the elastic element toward the pin, the second seal ring includes a dimensionally stable seal section that is configured to sealingly interact with the pin, and the second seal ring is connected to the cup either directly, or via the elastic element or via an elastic retainer. Also a method of installing the cup assembly.

A rear-wheel drive shaft (1) includes a fixed type constant velocity universal joint (3), a plunging type constant velocity universal joint (2), and an intermediate shaft (4) coupling both the constant velocity universal joints to each other. A ratio (PCD.sub.BALL(f)/D.sub.BALL(f)) of a pitch circle diameter (PCD.sub.BALL(f)) of balls (33) of the fixed type constant velocity universal joint (3) to a diameter (D.sub.BALL(f)) of each of the balls (33) is set from 3.70 to 3.87. A ratio (PCD.sub.BALL(s)/D.sub.BALL(s)) of a pitch circle diameter (PCD.sub.BALL(s)) of balls (23) of the plunging type constant velocity universal joint (2) to a diameter (D.sub.BALL(s)) of each of the balls (23) is set from 3.3 to 3.6.

A structural unit for assembly to a trunnion of a universal joint bearing providing a cup, a sealing ring, which is fixed to the cup, and a shield, which is connected to the cup in a state in which the structural unit is not assembled to the trunnion. The cup includes a bottom and the sealing ring provides at least one sealing lip that points in a direction with an axial component towards the bottom.

The universal joint (5, 7) includes first and second forks (23, 25) each having a pair of arms (61) with seats (61.1) for respective trunnions (27.1) of a spider (27). The arms (61) extend from an outer edge (91.1) of a collar (91) provided to increase the stiffness of the arms and reduce bending deformations thereof under heavy load operating conditions.

The operating device comprises a cable having a cable end, a coupling member, and a base. The coupling member has a coupling member-side facing surface facing the cable end, the coupling member-side facing surface is provided to the base so as to be inclined at a predetermined inclination angle with respect to the coupling member-side facing surface in an unloaded state, and the cable end has a cable end-side facing surface facing the coupling member-side facing surface. The coupling member-side facing surface and the cable end-side facing surface are configured not to interfere with each other when the coupling member is inclined.

A coupling arrangement for coupling a driving means, typically a motor, to a hollow rotor and stationary shaft combination, which arrangement includes a rotor having a working formation and hollow cylindrical member extending axially from a shoulder formation (not shown) at one end of the working formation, the member provided with a thread (not shown) on its outside, which, in use is threaded into a complementary cylindrical hollow part of the motor and wherein the threads have a tightening direction which is the same as the direction of the motor, such that in use, when the motor drives the member, the member is tightened onto the rotor.

A compact angular actuator allows for angular displacement between a first section and a second section. The first section comprises a cam that is circular in cross section and has a wedge-shaped face. The second section comprises two or more constraint components that are in contact with the face of the cam. A hinge joins the first section and the second section in proximity with one another. As the cam is rotated about an axis that is perpendicular to and extends through a center of the circular cross section, the position on the face that the constraint components are in contact with changes. As a result, a force is imparted between the first section and the second section, changing the angular displacement between the two. The actuator fits within a compact volume and allows for precise controlled angular displacement, while allowing that displacement to be maintained without power consumption.
