Abstract:
1. A tire inflation system configured to mount to a wheel, the wheel having a rotational axis, the inflation system comprising: a drive mechanism that rotatably mounts to the wheel, the drive mechanism comprising: a channel that encircles the rotational axis; multiple masses movably contained within the channel, the multiple masses operable between: a pumping mode, wherein the masses are arranged in a pumping configuration; and a non-pumping mode, wherein the masses are arranged in a non-pumping configuration; a pumping mechanism that statically mounts to the wheel and fluidly connects to a tire interior, the pumping mechanism comprising an actuating element and a chamber; and a force translation mechanism statically connected to the channel, the force translation mechanism configured to transform a relative rotation between the drive mechanism and the pumping mechanism during the pumping mode into actuating element reciprocation.
