Abstract
The invention relates to a toroidal inner tube (30, 130). The invention is characterized by the fact that the inner tube (30, 130) is in the form of a flexible corrugated tube (40, 140) that is curved to form a closed loop, the tube comprising alternating crest rings (46, 146) and trough rings (48, 148), the tube presenting a radius (R) and, when measured in a plane perpendicular to the axis of the tube, the radial thickness of at least one of the crest rings is less than the radial thickness of at least one of the trough rings (48, 148).
Claims21
A toroidal inner tube, in the form of a flexible corrugated tube that is curved to form a closed loop, the tube comprising alternating crest rings and trough rings, the tube presenting a radius and, when measured in a plane perpendicular to the axis of the tube, the radial thickness of at least one of the crest rings is less than the radial thickness of at least one of the trough rings.
A wheel configured to be mounted on a vehicle wherein the wheel comprises:
- a running device comprising a contact surface configured to come into contact with the ground during travel of the vehicle, and defining an internal housing;
- and
- an inner tube in the form of a flexible corrugated tube that is curved to form a closed loop, the tube comprising alternating crest rings and trough rings, the tube presenting a radius and, when measured in a plane perpendicular to the axis of the tube, the radial thickness of at least one of the crest rings is less than the radial thickness of at least one of the trough rings, the inner tube being arranged in the internal housing of the running device.
