<p>#CMT# #/CMT# The wheel (16) has peripheral rim (17), a central hub (18) and connecting spokes (26, 27) between the rim and the hub, where the spokes are stretched. An end of the spoke is extended by an end which has a tapered central recess for receiving a screw for adjusting tension. The spokes are stretched to an initial tension corresponding to a normal tension value reduced from a value corresponding to a compression force which can be supported by each spoke. #CMT# : #/CMT# An independent claim is also included for a rolling equipment with a frame, wheels and a transmission system. #CMT#USE : #/CMT# Used for cycle. #CMT#ADVANTAGE : #/CMT# The spokes are stretched to the initial tension corresponding to the normal tension value reduced from the value corresponding to the compression force which can be supported by each spoke, thus permitting to improve the endurance of the spokes, rim and hub, while avoiding the relaxation during normal usage and avoiding problems of geometry e.g. radial run out and lateral run out. The wheel permits to highly reduce the compression of the rim and permits to increase the resistance to the fatigue. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of a rear wheel. 16 : Wire wheel 17 : Peripheral rim 18 : Central hub 26, 27 : Connecting spokes 27a, 27b : Gripping ends.</p> |
