Abstract
Transmitting actuating forces from an actuator to a swashplate of an axial piston unit through a pin extending from a lever of the swashplate induces torsional stresses in the lever. The present invention overcomes this problem by securing a lever to a swashplate so that a distal end portion thereof extends into a slot of an actuator. The distal end portion has a cylindrical shaped surface pivotally seated in a mating socket formed in a slide block positioned within the actuator slot. The actuating forces transmitted from the actuator to the lever are thus transmitted in a straight line motion with minimal torsional stresses introduced into the lever.
