Abstract: A transmission is provided comprising: a first pulley assembly rotatable about a first axis; a second pulley assembly rotatable about a second axis; an endless member coupling the first pulley assembly and the second pulley assembly; an idler pulley engaging the endless member and rotatable about an idler axis, the idler pulley being movable between a first position and a second position; a tensioner assembly coupled to the idler pulley, configured to control tension in the endless member and comprising: a tensioner spring having a spring axis and biasing the idler pulley towards the second position; and a tensioner arm rotatable about a tensioner axis and coupling the tensioner spring to the idler pulley, the tensioner arm defining a spring linkage extending between the tensioner axis and a spring coupling point, wherein a spring angle is defined between the spring axis and the spring linkage.

Abstract: A segmented pulley defining an outer peripheral surface for engaging an endless member of a segmented pulley transmission is provided. The segmented pulley comprises: a plurality of pulley segments configured to be sequentially movable between an engaged region and a disengaged region to transition the endless member between the segmented pulley and a concentric pulley in the segmented pulley transmission, each of the pulley segments having a body defining a portion of the outer peripheral surface. The plurality of pulley segments includes a transition segment having an integrated support extending from the body of the transition segment, the integrated support being configured to support the endless member when transitioning the endless member between the segmented pulley and the adjacent pulley in the segmented pulley transmission. A segmented pulley transmission comprising the segmented pulley is further provided.

Abstract: An actuator system for moving a plurality of pulley segments of a segmented pulley between an engaged region and a disengaged region is provided. The actuator system comprises: a deflector configured to rotate at least between a first position and a second position; and a plurality of followers, each of the followers comprising a protrusion configured to engage the deflector to move the respective one of the pulley segments between the engaged region and the disengaged region, wherein the deflector is configured to move between the first position and the second position to selectively engage the plurality of followers and direct each of the followers between an engaged position and a disengaged position, to move the plurality of pulley segments between the engaged region and the disengaged region. A segmented pulley transmission comprising the actuator system is further provided.
