Abstract: A wheel for a vehicle, including a rim (10) having axially-spaced support portions (12, 14) on which respective annular tire—supporting elements (34,36) are engageable; wherein one of the support portions is of larger diameter than the other.

Abstract: A wheel construction (10) includes a wheel rim (11) which in use, at a tire side (12) of the rim (11), receives a tire (14), the rim (11) being circular and having axially inner and outer portions (16,15), and a mid-portion (18) between the axially inner and outer portions (16,15), the mid-portion (18) including a circumferential well where the radius of the wheel rim (11) is a minimum, and each axially inner and outer portion (16,15) providing a flange (22), a connecting surface (23) adjoining the flange (22) and extending axially towards the mid portion (18), the flange (22) and a part of the connecting surface (23) providing a seat for a bead of the tire (14), and there being a side part (19,20) between the connecting surface (23) and the mid portion (18) and wherein for at least one of the inner and outer portions (16, 15), the connecting surface (23) is frusto-conical having an axial end (24) of greatest radius and an axial end (25) of least radius, the connecting surface (23), at its axial end (24) of g

Abstract: A method of considering the dynamic behavior of a movable member of a machine for performing a wheel fatigue test, the wheel including a disc and a rim, the method including mounting the wheel by fixing the wheel rim relative to a fixed structure of the machine, and securing the disc relative to the movable member which is movable to transmit a cyclical bending moment to the wheel, exerting a cyclical force on the movable member to generate the bending moment, at a distant position from the wheel, and while exerting the cyclical force, determining an indication of bending moment in the movable member at a first position between the wheel and the distant position, determining an indication of bending moment in the movable member at a second position between the first position and the distant position, and using the indications of bending moment at both of the first and second positions to determine an actual bending moment applied to the wheel.
