Producing a metal component with a casting-and-forming tool
A metal component is produced using a casting-and-forming tool by casting a melt of a metal alloy into the casting-and-forming tool, wherein the melt is poured from above into a base part or reservoir of the casting-and-forming tool at a first pressure, applying pressure to the melt between the base part and an upper part while the melt is solidifying to a component, wherein the solidifying melt is pressurized at a second pressure, which is larger than the first pressure, when the melt is at least partly, i.e., mostly solidified to form a component compressing the component by relative movement of the base part to the upper part so as to compress the component with a third pressure, which is higher than the second pressure.
Manufacture of wheels
A method of making at least a component for a rim base of a multi-piece wheel for a vehicle, comprising providing a workpiece of tubular configuration and hot upset forging the workpiece in press tooling to form a part thereof to a required configuration, wherein the part of the workpiece is heated to a forging temperature in situ in the press tooling, preferably by induction heating.
VEHICLE WHEEL AND METHOD FOR PRODUCING SUCH A WHEEL
A vehicle wheel includes an annular rim defining an axis and inboard and outboard sides. The rim includes an outboard bead seat, an inboard bead seat, an outboard well flank connected to the outboard bead seat and extending radially inwardly and towards the inboard side of the rim, and an inboard well flank connected to the inboard bead seat and extending radially inwardly and towards the outboard side of the rim. The rim further includes a well portion defined between the outboard and inboard well flanks, wherein the well portion is formed by a plurality of curved and straight portions linked together. The well portion has at least three transition portions having varying thickness cross-sectional profiles. A wheel disc is secured to the rim. The wheel disc includes a hub located centrally within the wheel disc and has a plurality of bolt holes formed therein.
Method for manufacturing a one-piece wheel by forging and a one-piece wheel manufactured thereby
A method for manufacturing a one-piece wheel by forging includes: producing an integral forging comprising: a disc portion, a rim portion, and an annular protrusion protruding from one side of the disc portion in a forging method; producing an outer bend by bending the annular protrusion through a flow-forming process; and forming a hollow portion by welding one end of the outer bend to one side of the rim portion.
METHOD FOR MANUFACTURING A LIGHT-ALLOY HYBRID WHEEL INCLUDING A FRONT FLANGE AND A RIM
A process for manufacturing a light-alloy hybrid wheel implements the following separate operation phases: making a flange with an internal profile capable of constituting a tire bead seat; making a rim with, on one side, an outer profile capable of constituting a tire bead seat and, on the other side, a circular flank for assembly with a part of the flange; assembling the flange with the rim, at the seat of said flange and the circular flank of the rim. The rim is made according to the following consecutive operations: an operation of manufacturing a circular flank; then an operation of expanding said circular flank to the size of the final rim in a single step; then an operation of cold or hot flospinning of said circular flank so as to obtain the rim in the final shape and profile thereof, comprising a shoulder only on the side that will not be welded to the flange.
Method of manufacturing hollow axle shaft for a vehicle
A hollow axle shaft for transmitting rotational motion from a prime mover to a wheel of a vehicle comprises an elongated member. The elongated member extends along an axis between a first end and a second end. The hollow axle shaft further comprises a flange at the first end and extending radially away from the axis for receiving the wheel. The flange is integral with the elongated member. A method of manufacturing the hollow axle shaft comprises the step of providing the elongated member comprising a material and defining a bore extending along the axis between the first and second ends, and the step of forming the flange with the material at the first end.
METHOD AND APPARATUS FOR MANUFACTURING SPOKES
A method and a device are provided for manufacturing spokes from a wire material, in particular for at least partially muscle-powered two-wheeled vehicles. The spokes include a spoke shaft having at least two shaft sections. The shaft sections differ in at least one cross-section. For shaping the cross-sections, the wire material is reshaped at least in sections by means of a shaping tool. The relative position of the wire material relative to the shaping tool is varied in the axial direction during reshaping. For shaping the cross-sections in the two shaft sections the relative position of the wire material relative to the shaping tool is varied by way of different positioning movements.
Wheel bearing apparatus and its manufacturing method
A wheel bearing apparatus has an outer member, an inner member and double row rolling elements freely rollably contained between double row inner raceway surfaces and outer raceway surfaces of the inner member and the outer member. A plurality of bolt insertion bores, that fastening bolts pass through to fasten to the knuckle, are formed on the body mounting flange at plurality of positions circumferentially along the body mounting flange. The outer member is previously formed by hot forging. A seating surface for the fastening bolts is formed on an outboard-side surface of the body mounting flange by cold forging.
DRIVE WHEEL BEARING AND METHOD OF MANUFACTURING THE SAME
Disclosed are a drive wheel bearing and a method of manufacturing the same. The drive wheel bearing includes: a wheel hub which is integrally and rotatably fastened to a vehicle wheel; an inner race which is fitted with the wheel hub and integrally and rotatably coupled to the wheel hub; an outer race which rotatably supports the wheel hub and the inner race in a state in which the wheel hub and the inner race are fitted into the outer race; rolling elements which are interposed between the outer race and the wheel hub and between the outer race and the inner race; and a constant velocity joint which is integrally and rotatably connected to the wheel hub or the inner race by means of a face spline in order to receive power from an engine and transmit the received power to the vehicle wheel, in which the face spline of each of the wheel hub and the constant velocity joint have a structure in which teeth having the same size and tooth grooves having the same size radially extend, and are alternately and continuously arranged in a circumferential direction, and as a result, it is possible to smoothly transmit rotational power of the engine to the vehicle wheel through the wheel bearing.
Wheel hub and associated motor vehicle
A wheel hub for receiving a vehicle wheel, the wheel hub having a central region with a central opening. In order to achieve a reduction of the forces acting on wheel screws, it is provided that (i) the wheel hub includes at least four screw-in openings for screwing in a respective wheel screw; (ii) the wheel hub includes a number of stiffening ribs corresponding to the number of screw-in openings, which ribs extend obliquely or radially outward; (iii) in each case, two circumferentially adjacent stiffening ribs are connected to one another by a linearly extending connecting web, wherein the connecting web between the stiffening ribs has no connection to the central region; and (iv) a screw-in opening is arranged in each connecting web.
