Abstract
Abstract This disclosure relates to a process for the production of vehicular wheels and finds particular utility in wheels in which a steel rim must be united to a magnesium or aluminum spider. The aluminum or magnesium spider is united to the steel rim by a combination of adhesive action and metal interlocking since steel is essentially unweldable to either aluminum or magnesium.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
135 words
The process of producing a vehicular wheel comprising providing a wheel rim and a wheel spider adapted to be inserted into and attached to the wheel rim, the interior of said wheel rim being a surface of revolution, the portions of said wheel spider to be attached to the wheel rim being also surfaces of revolution and dimensionally complementary to the wheel rim, the clearance between the wheel rim and the complementary portions of the wheel spider being no greater than can be spanned effectively by a resinous adhesive, applying a resinous adhesive to either the wheel rim or wheel spider on the surfaces to be joined, inserting the wheel spider into the steel rim, forcing the wheel rim into peripheral mechanical interlocking engagement with the wheel spider and permitting the resinous adhesive to cure.
Claim 2
Dependent Claim
135 words
The process of producing a vehicular wheel comprising providing a wheel rim and a wheel spider adapted to be inserted into and attached to the wheel rim, the interior of said wheel rim being a surface of revolution, the portions of said wheel spider to be attached to the wheel rim being also surfaces of revolution and dimensionally complementary to the wheel rim, the clearance between the wheel rim and the complementary portions of the wheel spider being no greater than can be spanned effectively by a resinous adhesive, applying a resinous adhesive to either the wheel rim or wheel spider on the surfaces to be joined, inserting the wheel spider into the steel rim, forcing the wheel rim into peripheral mechanical interlocking engagement with the wheel spider and permitting the resinous adhesive to cure.
Claim 3
Dependent Claim
51 words
The process recited in claim 1 in which the wheel spider is provided with at least one peripheral groove prior to its insertion into the wheel rim, and the wheel rim is deformed to at least partially fill said grooves and rigidly mechanically secure the wheel rim to the wheel spider.
Claim 4
Dependent Claim
43 words
The process of claim 2 in which at least a portion of the resinous adhesive is placed in the peripheral grooves whereby it is positively forced between the wheel rim and wheel spider when the wheel rim is deformed into the wheel spider.
Claim 5
Dependent Claim
27 words
The process of claim 1 in which an interference fit is provided between the exterior of the wheel spider and the complementary surface of the wheel rim.
Claim 6
Dependent Claim
17 words
The process recited in claim 1 in which the wheel spider is constructed of aluminum or magnesium.
