Abstract:
To provide a wheel support bearing assembly coupled with the knuckle of a type made of an aluminum alloy, in which an undesirable occurrence of electrocorrosion resulting from a galvanic cell developed at a surface area where the wheel support bearing assembly contacts the aluminum alloy knuckle is substantially eliminated, a wheel support bearing assembly is provided with an outer member (1) having an inner peripheral surface formed with raceways (4), an inner member (2) having raceways (5) defined therein in alignment with the raceways (4) in the outer member (1), and rows of rolling elements (3) positioned between the raceways (4 and 5) in the outer and inner members (1 and 2), respectively. The outer peripheral surface of the outer member (1) is formed with a vehicle body fitting flange (1a) for securement of the wheel support bearing assembly to a knuckle (14) made of an aluminum alloy and the outer peripheral surface of the inner member (2) is formed with a wheel mounting flange (2a) for the support of a vehicle wheel. An electrically insulating layer (17) is provided at a surface area of contact between the outer member (1) and the knuckle (14), that is, on a portion of the outer peripheral surface of the outer member (1) that is received in a bearing bore (14a) of the knuckle (14) and one of axial end faces of the vehicle body fitting flange (1a).
Abstract:
This invention concerns a method of joining forged, machined, formed or cast components with a metal tube. In another aspect, it concerns a metal object constructed according to the method. The tube is heated to expand its diameter, but not sufficiently to anneal it, or otherwise adversely affect its mechanical properties. Then, while the tube is still hot, it is pushed over part of the central component so that part of the tube overlies a circumferential groove in the central component. Then, while still hot, the circumferential part of the tube which overlies the groove, is rolled into the groove, so that when cooled the rolled part of the tube is clamped into the groove. The invention is particularly, but not exclusively, applicable to the construction of vehicle wheels having a forged, machined, formed or cast hub or center and a metal rim.
Abstract:
A process for casting or forging a wheel disc upon the end of a metal hoop. The metal hoop is then formed into a wheel rim. The rim and disc are machined to assure concentric tire bead seats.
Abstract:
This invention relates to an full face vehicle wheel including a wheel rim joined to a wheel disc. The wheel disc defines an axis and includes a body having a centrally located wheel mounting surface and an outer annular portion. The outer annular portion defines an outboard tire bead seat retaining flange of the full face vehicle wheel, and includes an outer surface and an inner surface. The inner surface of the outer annular portion defines an inner fit up surface of the wheel disc. The wheel rim includes an inboard tire bead seat retaining flange, an inboard tire bead seat, an axially extending well, and an outboard tire bead seat. The outboard tire bead seat terminates at a generally circular shaped outer having a substantially full radius outer diameter along the entire periphery thereof. The circular shaped outer end defines a non-flat point of contact surface. When the outer non-flat point of contact surface of the outer end of the wheel rim is positioned adjacent the inner fit tip surface of the wheel disc, the outer non-flat point of contact surface of the wheel rim abuts the inner fit up surface of the wheel disc at a single point of contact therebetween and at least a portion of the outer surface of the outer end of the wheel rim is spaced from the inner fit up surface of the wheel disc to form a generally annular groove for receiving a weld to join the wheel rim and the wheel disc together and produce the finish full face vehicle wheel.
Abstract:
The rim spider of a two-piece wheel for a motor vehicle is provided with hollow spokes in which a metal foam core is arranged and remains. The rim spider is connected with a rim by way of weld ring surfaces which are friction welded. The metal foam core is provided in a special manner with a partial core which is supported on a top core of a casting die tool so as to provide positioned bearing in the casting die tool. By way of slides, which are arranged in a distributed manner on a circumference of the rim spider, an influence on heating and cooling behavior, during and after casting, is exercised.
Abstract:
This invention relates to an improved full face vehicle wheel including a wheel rim joined to a wheel disc. The wheel rim defines an axis and includes an inboard tire bead seat retaining flange, an inboard tire bead seat, an axially extending well, and an outboard tire bead seat. The outboard tire bead seat of the wheel rim terminates at an endmost surface. The wheel disc includes a body having a centrally located wheel mounting surface and an outer annular portion. The outer annular portion of the wheel disc defines an outboard tire bead seat retaining flange of the full face wheel. The outer annular portion of the wheel disc includes a protuberance formed therein. The protuberance defines a generally radially extending non-flat outer surface and a generally radially extending inner surface. The inner surface of the protuberance defines a fit-up surface for receiving the endmost surface of the wheel rim and a weld to join the wheel disc to the wheel rim. The protuberance in the outer flange of the wheel disc is effective to improve the styling of the full face wheel.
Abstract:
A full face wheel assembly comprises a full face disc and a rim. The disc is preferably cast from aluminum whereas the rim is rolled from aluminum strip stock. The full face disc comprises an outboard bead seat flange, an outboard bead seat and an outboard well side wall. The disc may also include lightener pockets or a continuous re-entrant channel adjacent the outboard bead seat. The rim comprises an inboard bead seat flange, an inboard bead seat, an inboard leg, and a deep well. The disc and rim are welded together in the deep well or bead seat regions by gas metal arc welding, electron beam welding or other suitable welding technique.
Abstract:
A vehicle wheel having a wheel rim heat shrunk onto a wheel disc and mechanically secured to the wheel disc by an interlocking segmented grooves and beads, and a method for fabricating same. A resilient material including an adhesive is disposed between the wheel disc and the wheel rim. The adhesive bonds the wheel rim to the wheel disc while the resilient material forms air-tight seal therebetween.
Abstract:
An improved vehicle wheel construction having an injection molded generally annular filler ring disposed in a radially inwardly facing circumferential cavity of the wheel to prevent material from accumulating in the circumferential cavity of the wheel and causing an out-of-balance wheel condition and method for producing the same is disclosed. The method includes the steps of (a) providing a rim and a disc; (b) securing the rim and the disc together to produce a wheel construction which defines a radially inwardly facing circumferential cavity; (c) positioning the wheel on a carrier; (d) probing the wheel to make sure the wheel is properly positioned on the carrier in a predetermined position and if not, moving the wheel to the predetermined position; (e) inserting a plug through a valve stem opening formed in the wheel (f) moving a mold into engagement with the inner surface of the wheel adjacent the circumferential cavity, the mold including an outer portion formed of a pliable material and having a profile which generally corresponds to the profile of the adjacent surfaces of the wheel, the pliable outer portion of the mold operative to take up any variations in the wheel profile so as to form a seal at the wheel engagement surfaces and thereby isolate the circumferential cavity; (g) injecting a filler material through a passageway formed in the mold; and (h) maintaining the mold in engagement with the inner surface of the wheel adjacent the circumferential cavity until the filler material cures to a non-reactive state and forms an injection molded generally annular filler ring of a generally solid material.
Abstract:
A method for fabricating a vehicle wheel having a wheel rim mechanically rolled onto a wheel disc. The wheel disc includes at least one continuous circumferential bead or groove. During the rolling operation a complementary groove or bead is formed in the wheel rim. The bead is received by the groove to mechanically secure to the wheel rim to the wheel disc. A resilient material including an adhesive is disposed between the wheel disc and the wheel rim. The adhesive bonds the wheel rim to the wheel disc while the resilient material forms air-tight seal therebetween.
