Abstract
A wheel mount for a motor vehicle including a hub which is welded to another part, such as a swivel joint or a holding part. The hub carries on it the inner ring of the anti-friction bearing for the hub. Projecting axially from the hub and from the other part are correspondingly radially spaced projections which, prior to welding and deformation of the projections, are of lengths great enough to hold the hub and the other part axially apart. Upon welding temperature being achieved at the projections, e.g. by friction, the hub and the other part are pressed together which deforms the projections, forming beads of deformation, and the hub and other part are welded at the beads of deformation. The hub and other part are pressed together until the axial ends of the hub and other part contact. There is radial clearance at both sides of the projections and the beads of deformation for preventing direct heat transmission from the sides of the projection and the beads of deformation to the hub, and particularly to the inner ring of the bearing which would be damaged by that heat.
