Pneumatic wheel assembly

摘要

A pneumatic wheel assembly includes a tire, mounted to a wheel rim, including an inflation valve, one default air chamber and one or more spare inner chambers, which spare inner chambers are inflatable if necessary, such as in case of puncture of the tire, where the inflation valve includes a gas inlet and a multi-way valve having selectable switching states to fluidly connect the inlet to either one of the default chamber or one of the inflatable inner chambers thereby allowing for individual inflation of any of the chambers, and a perforated rigid chamber extending circumferentially around the rim between the tire beads and fluidly connectable to a gas outlet.

1. A pneumatic wheel assembly comprising a tire, mounted to a wheel rim, comprising an inflation valve, one default air chamber and one or more spare inner chambers, which spare inner chambers are inflatable if necessary, such as in case of puncture of the tire,
wherein said inflation valve comprises a gas inlet and a multi-way valve having selectable switching states to fluidly connect said inlet to either one of the default chamber or one of the inflatable inner chambers thereby allowing for individual inflation of any of said chambers (5, 31, 32), and a perforated rigid chamber extending circumferentially around the rim between the tire beads and fluidly connectable to a gas outlet.
