Each hub is attached to a respective frame member by an attachment member pivotally attached to the respective frame member by a pivotal mounting and a suspension spring pivotally attached to the hub by a spherical bearing and to the respective frame member at a pivot mounting. The connections of the hub allow for limited pivotal movement of the hub about transverse and longitudinal axes relative to the frame members.
