Wheel

A lightweight wheel including:

• a central hub,
• a circular outer flexible rim,
• the hub and rim being interconnected by spring means mounted between the hub and the rim,
• the central hub being cylindrical, the hub being formed of an endless band of carbon fibre reinforced polyamide 12 material, the hub having an outer circumferential face,
• the rim being formed of an endless band of carbon fibre reinforced polyamide 12 material having an inner circumferential face and an outer circumferential face,
• the spring means comprising an endless spring band of carbon reinforced polyamide 12 material,
• said spring band being looped to form a plurality of radial loops extending between the hub and the rim,
• a pair of spaced-apart limit stop discs mounted on the hub and extending radially outwardly, said discs being coaxial with the hub, an outer circumferential edge of each disc located intermediate the outer face of the hub and the inner face of the rim,
• a tyre strip thermoplastic elastomer being mounted on the outer face of the rim.

A lightweight wheel, including:

• a central hub,
• a circular outer flexible rim,
• the hub and rim being interconnected by spring means mounted between the hub and the rim,
• the hub, rim and spring means each being constructed of either titanium or a carbon fibre reinforced nylon material,
• the spring means comprising an endless looped spring band extending about the hub between the hub and the rim.
