Abstract
This invention relates to a wheel supported heavy load carrying vehicle which comprises a frame upon which a load may be supported. The frame includes a structural cross-member. Unlike the prior art, the spherical bearing is made an integral part of the cross-member. An axle box assembly is used to support the wheels which support the bulk of the load. The box assembly has a nose cone which has a concave bearing which mates with the spherical bearing on the structural cross-member.
