Abstract

The present subject matter relates to clutch arm and release devices and methods such as for a variable speed transmission. A clutch linkage can include a control shaft pivotable about an axis, a substantially U-shaped arm connected at two points to the shaft, and a plurality of projections positioned on the arm. The arm can be moved between positions in response to rotational movement of the control shaft, and the projections can thereby engage and exert a force on a movable sleeve to move the sleeve, such as for causing a clutch bearing to move between an engaged and a disengaged position.
