Title:
LIGHT-ALLOY VEHICULAR WHEEL
Document Type and Number:
WIPO Patent Application WO/1995/007826
Kind Code:
A1
Abstract:
This invention provides a light-alloy vehicular wheel. In this light-alloy vehicular wheel, a forged material or a cast and forged material is used for at least a disc (1, 6, 13) and a rim (5, 7, 8) or an inner rim member (3), which is produced separately from the disc, is jointed with the disc (1, 6, 13) by a friction grip jointing method. It is possible to joint a unitary molded product consisting of an outer rim member (2, 12) and disc (1, 13) and composed of forged light alloy or cast and forged light alloy with the inner rim member (3) of cast light alloy by a friction welding method, and joint a unitary molded product consisting of outer and inner rim members and constituting a rim (5) of a cast light alloy with a disc (6) of a forged light alloy by a friction welding method. A primary body (8) of the inner rim member can also be spin molded by molding outer and inner rim members unitarily by a casting method.
