  • Patent number: 5486053
    Abstract: A bearing unit for a vehicle wheel comprises a three-point or four-point bearing with an inner and an outer race, each with a bearing groove containing a series of rolling elements, which inner race has means for fixing to the suspension construction for the wheel. At least the outer race has a radially inward pointing bearing flange, which outer race bearing flange is provided with means for fixing a wheel thereto. The bearing unit can also be used for a driven front wheel comprising a constant-velocity joint, in which the outer ring of the joint has an external diameter which is at most equal to the internal diameter of the outer race, and is smaller than the internal diameter of the inner race. Because the joint is situated in the bearing, the bearing unit is compact.

  • Patent number: 5106341
    Abstract: A coupling mechanism for coupling two elements in a manner providing for transfer of the rotation moment of one element to the other element. The mechanism comprises at least two coupling element (11, 12), each coupling element having a pair of radially outwardly directed spherical pivot portions (11', 12'). The spherical pivot portions of the coupling elements are housed in an intermediate element (8) comprising a continuous inner ring member (10) defining spherical pockets for the pivot portions and an outer ring (9) circumscribing the inner ring. The pivot portions (11', 12') are rotatable at least around their cardioids while being contained in pockets formed in the inner ring of the annular intermediate element (8), such that the one coupling element can swivel in one plane and the other coupling element can swivel in a plane perpendicular to the first relative to the intermediate element (8).

  • Patent number: 4995850
    Abstract: A homokinetic coupling for coupling two components in such a manner as to accomodate swiveling motion therebetween. One component includes a housing and the other component is a shaft with a spherical end portion received in the housing. The end portion includes grooves which open radially inwardly to a central hollow. The housing includes a corresponding number of grooves. Balls are disposed in the corresponding grooves of the end portion and housing. A helical coil tension spring is disposed concentrically within the hollow to provide a radially outward spring force on the balls.

  • Patent number: 4964840
    Abstract: A steering control mechanism of a vehicle steering box connected to a steering wheel through a shaft and a coupling for coupling two generally shaft-shaped elements in such manner that a rotational force can be transferred from one element to the other whereby the cardioids of these elements can form different angles with each other, including an intermediate element to which two swivelling coupling elements are connected, each of which is connected to the shaft and each of which has two opposing parts located on both sides of the cardioid of the swivelling coupling element which are connected to, and rotate around the intermediate element so that the one swivelling coupling element can swivel in one plane and the other swivelling coupling element can swivel in a plane perpendicular to the first, with regard to the intermediate element, the intermediate element being generally an endless section or an annular part, and that the opposing parts of each swivelling coupling element are formed by two pivot pins lo

  • Patent number: 4946296
    Abstract: A device for sealing and generating electrical pulses in a bearing assembly including fixed and rotating bearing rings especially a wheel bearing for motor vehicles. The device consists of a sealing section on the fixed bearing ring with an embedded pulse generator for detecting rotational movement and a sealing section on the rotating bearing ring having cells a certain distance apart from each other which activate the pulse generator. The fixed bearing ring (4, 19) rotates with respect to the sealing section (2) which is secured against rotation by way of a machine element (1, 24), which holds the fixed bearing ring (4, 19).

  • Patent number: 4900236
    Abstract: Ceiling fan consisting of a rotatable assembly to which the fan blades are attached and a stationary assembly connected to capable of being connected to a suspension means. These assemblies have a common centerline, and the rotary assembly comprise the rotor and the stationary assembly the stator, located concentrically inside the rotor, of an electric motor. The rotatable assembly is mounted rotatable relative to the stationary assembly by means of a tubular member extending coaxially with the centerline and a shaft located therewithin. Two bearings are located at a distance one above the other and are mounted between the shaft and the tubular member, at least one of which bearings comprises a rolling bearing. The other one of the two bearings comprises a journal bearing.

  • Patent number: 4438987
    Abstract: In a magnetic bearing system, wherein the gap between relatively moveable elements is controlled by variation of magnetic force therebetween, light is directed from one of the members onto the other member, and reflected back, the reflected light being converted to an electrical signal. The magnetic force between the members is controlled as a direct function of the magnitude of the reflected light. The optical system may include optical fibers for directing the light, and markings may also be provided on the other member to enable determination of relative speed between the members in a further transducing system.

  • Patent number: 4330911
    Abstract: A process for the production of objects consisting of at least two parts, such as the inner and outer rings of a bearing movable relative to one another. One part is substantially enclosed within the other part and at least one of the parts comprises at least two separate elements. These elements are placed against one another and held in the correct position in relation to the other part. Thereafter, a high energy beam welding means such as a laser or electron beam is set up over the juncture line between the two elements and operated while at least the two elements are moved bodily in order to move the juncture line past the energy beam and weld the pieces together. The process also includes the use of one or more loose members such as rolling elements which are introduced at the time the two elements of one part are assembled in the correct position in relation to the other part and thereafter the two elements of the one part are welded together.
