Drive for motor vehicle - has centrifugal force control with cut=out in freewheel inner section housing pivoting contact arms with eccentric fulcrum

摘要

The drive has a centrifugal force actuated control which is provided with at least one cut-out (20) in the freewheeling inner section (15). The inner section has a radial bore (21) housing a pressure spring (22), and two pivotting contact arms (24) are installed in the cut-out (20). The fulcrum of each arm is eccentric and lies inside the outer perimeter of the freewheeling inner section (15). By a spring (25) each arm is loaded in the direction opposed to centrifugal force. A circumferentially moving clamp (26) is installed between the arms and inner section. ADVANTAGE - The arrangement permits automatic effective freewheeling in both rotational directions.
