  • Patent number: 12157161
    Abstract: To manufacture a holding flange intended to be inserted into a groove of an outer ring of a rolling bearing, from a metal plate having a plate thickness measured between a front face and an opposite rear face of the metal plate, a method is performed in at least two steps. By penetration of a first tool, along a reference axis perpendicular to the plate and in a direction of penetration from the front face over an intermediate depth less than the plate thickness, the material initially located inside a front geometric envelope is pushed back into a volume axially located between the intermediate depth and the rear face of the holding flange and delimited by a blank geometric envelope.

The aim is to improve the uniformity of the end-side toothing arrangement and to allow a greater tooth depth. This is achieved by two method steps in that, in a first step before the reshaping of an end piece of a hub, a die is axially arranged on the rolling bearing in a preassembled state and, in a second step during the reshaping of the end piece and the shaping of the end-side toothing arrangement, the die radially delimits a radial recess of the rolling rivet collar as it forms. In addition, the die reduces or prevents radial widening of the inner ring.

  • Patent number: 8690441
    Abstract: A wheel bearing device for a motor vehicle, having an inner ring arrangement, formed for rotationally fixed reception of a first rotary partner, particularly an axle stump, or a shaft, an outer ring arrangement, which is connected and/or connectable and rotationally fixed with a second rotary partner, a multitude of rolling elements, which roll between the inner ring arrangement and the outer ring arrangement, so that inner ring arrangement and outer ring arrangement and/or the rotary partners are rotatable against each other, and an electric sensor device, which, using mechanical contact, is arranged and/or formed for detecting an operating status of the wheel bearing device. The sensor device has a stationary sensor element and a rotating sensor element, which can work together to form the mechanical contact. One of the sensor elements is connected with the inner ring arrangement without the interposition of the first rotary partner.

  • Patent number: 8678662
    Abstract: A drive wheel bearing device is provided with an outer member, an inner member, double-row rolling elements and a constant velocity joint. The inner member includes double-row inner races opposite outer races of the outer member, a first inner member, and a second inner member formed with at least one of the double-row inner races, the first inner member and the second inner member being inseparably coupled together at a flange-like swaged portion. The constant velocity joint includes an outer joint member press-fitted to an inner periphery of the first inner member with torque transmission means formed therebetween that transmits torque by engagement of a plurality of axially extending teeth, wherein the torque transmitting teeth of the first inner member have a tooth profile that is controlled within a specified range over the entire axial length of the teeth.

  • Patent number: 8636418
    Abstract: A wheel bearing arrangement, especially for utility vehicles, having a rotating outer ring (5, 6), a stationary inner ring (3, 2) and rolling elements rolling between these rings, the inner ring being fixed on a stationary axle journal (4) and the outer ring inside a wheel hub (1) having a signal transmitter (9). In order to make it easier to fit a sensor arrangement to the wheel bearing arrangement and to increase driving safety, a sensor (13) interacting with the signal transmitter is arranged so as to axially abut on the inner ring and is then fastened to the spindle by a fastening element (12, 16), thereby allowing, once the bearing rings are mounted, the sensor to be positioned on the inner ring via a stop surface formed onto the sensor and then to be permanently immobilized by a screw or other fastening element.

  • Patent number: 8631581
    Abstract: A method for forming a wheel bearing apparatus where the end portion of the cylindrical portion is pre-formed as a cylinder prior to its plastic deformation to form the caulking portion. A caulking tool with a punch and a swing shaft abuts against the end portion of the cylinder at a predetermined inclined angle relative to the inner circumferential surface of the cylinder. Teeth on the punch form the face-spline by plastically deforming the end face of the caulking portion. The swing shaft central axis is inclined at an angle relative to a central axis of the wheel hub. The face-spline is formed simultaneously with the formation of the caulking portion by advancing the caulking tool toward the wheel hub. A main shaft is rotated to cause a swing motion of the caulking tool.

  • Patent number: 8540582
    Abstract: A bearing device for a wheel suppresses backlash in a circumferential direction, has excellent coupling workability with a hub wheel and an outer joint member of a constant velocity universal joint, and has excellent strength owing to stable fitting between the hub wheel and the outer joint member. Projecting portions extending in an axial direction are provided on one of an outer surface of a shaft section of the outer joint member and an inner surface of a hole portion of the hub wheel. The projecting portions are press-fitted into the other along the axial direction, and recessed portions are formed in the other through press-fitting of the projecting portions. Thus, a recess-projection fitting structure is formed, in which the projecting portions and the recessed portions are held in close contact with each other through an entire region of fitting contact regions therebetween.
