Publication number: 20110241416Abstract: A rotary forming method for producing a rivet flange of a wheel hub on which a wheel bearing is mounted. A rivet flange is formed from a cylindrical part of a wheel huh by a hobbing tool oriented along a direction of the axis of rotation of the wheel hub. The method keeps material stresses low and accurately adjusts the preload of the bearing. For this purpose, first rotating rolling elements of at least one first row of rolling elements of the tool form the rivet flange. Axes of rotation of the first rolling elements form a first angle with the axis of rotation of the rolling bearing during the riveting operation, ensuring uniformity on the entire circumference of the cylindrical part of the wheel hub using a smaller deformation force while allowing the rolling bearing to be temporarily preloaded by a holding element even before the cold forming process.Type: ApplicationFiled: November 19, 2009Publication date: October 6, 2011Applicant: SCHAEFFLER TECHNOLOGIES GMBH & CO. KGInventors: Andreas Kaiser, Roland Langer, Sebastian Lorenz

Publication number: 20100066158Abstract: The two-piece wheel rim assembly includes first and second hub sections affixed together and rotatably mounted on an axle by a set of bearings which are longitudinally spaced apart on the axle. The hub sections have radially inboard wall segments and radially outboard segments. The inboard segments form a radial cavity about the axle longitudinally bounded by the bearings. An oil bath substantially fills the radial cavity except for a small thermal expansion air pocket. The thermal expansion air pocket is positioned above the axle and the bearings when the hub-tire combination is in use. The thermal expansion air pocket has a nominal size only sufficient to account for thermal expansion and contraction of the wheel.Type: ApplicationFiled: September 17, 2009Publication date: March 18, 2010Inventor: Thomas S.

Publication number: 20090045670Abstract: When an inner ring 3 of a driving-wheel supporting hub unit is fixed to a hub 2, a pressing die 24 is displaced downward and an annular working surface 27 at a lower end surface of the pressing die 24 is pressed against a front end of a cylindrical portion 13a over its whole periphery. Further, in this state, the pressing die 24 is pressed downward toward the hub 2 without rocking the pressing die 24 relative to the hub 2. Thus, the cylindrical portion 13a is plastically deformed radially outward along the working surface 27 simultaneously over its whole periphery. By adopting this method, the operation of plastically deforming the cylindrical portion 13a at the inner end of the hub 2 to form a caulking portion, can be easily and performed accurately. Accordingly, the structure of the caulking portion forming apparatus 21 can be simplified.Type: ApplicationFiled: March 29, 2007Publication date: February 19, 2009Applicant: NSK LTD.Inventors: Tatsuya Enomoto, Nobuyuki Hagiwara, Masahiro Yasumura

Publication number: 20080144985Abstract: An automotive vehicle has road wheels that are coupled to suspension uprights of the vehicle through wheel ends that have the capacity to monitor lateral loads that act on the road wheels at tire patches where the road wheels contact a road surface. Each wheel end offsets displacements that would be produced within the wheel end by vertical loads with displacements that would be produced by moments induced by the vertical loads, so that the remaining displacements within the wheel end reflect essentially lateral loads exerted at the tire patch. The wheel end contains a sensor and a target that the sensor monitors to detect the presence and magnitude of the displacements and hence the magnitude and direction of the lateral force at the tire patch. The sensor may also monitor angular velocity, angular position, and temperature.Type: ApplicationFiled: September 11, 2007Publication date: June 19, 2008Applicant: THE TIMKEN COMPANYInventors: Mark A.

Patent number: 6672681Abstract: A railway axle hub unit of the type including an axle box housing (1) for supporting a bearing, is provided with a sensor body (3, 9) containing sensors (4, 5) for detecting vibration in the vertical direction and the horizontal axial direction. The sensor body is mounted onto a stationary support element (2, 1, 15) rigidly secured to the bearing, preferably an annular sealing insert. The sensors perform monitoring of the operation condition of the hub unit by generating and transmitting signals indicative of the detected level of vibration to an electronic processing unit mounted on board of the railway vehicle or the train. The processing unit is capable of signalling in real time an impending failure and/or a damaged condition associated with the monitored hub unit.Type: GrantFiled: November 21, 2001Date of Patent: January 6, 2004Assignee: SKF Industrie S.p.A.Inventors: Roberto Moretti, Silvano Sema, Matteo Genero

Patent number: 4473129Abstract: The hub assembly comprises a wheel flange, a transmission joint and a rolling bearing. The confronting radial surfaces of the flange and the inner race of the bearing are separated throughout their height by a gap and consequently do not bear against each other. The connection between these two elements is achieved by means of a circumferential weld. By means of such an arrangement, there is avoided a harmful heating of the rolling bearing and of the joint by transmission of heat from the wheel flange.Type: GrantFiled: August 19, 1981Date of Patent: September 25, 1984Assignee: Glaenzer SpicerInventor: Pierre Guimbretiere
