The present disclosure describes methods, systems, apparatuses, and devices for facilitating actuating robots and automatic machines. Specifically, the present invention provides a capstan actuator with composite control coil. Further, the disclosed system may allow for multi-jointed robots, or other multiple degrees of freedom machines, to be constructed in a novel manner that allows for a single prime mover to supply motive power to many other degrees of freedom with very good control fidelity.

A system is provided for generating vacuum in a vehicle. The system includes a vacuum pump, an engagement clutch, an actuator, and a torque limiting clutch. The engagement clutch operatively connects a camshaft to the rotor. The actuator controls the clutch. The actuator is movable, based on air pressure in a vacuum conduit, between a low-pressure position in which the actuator causes the clutch to operatively disconnect the camshaft from the rotor, and a high-pressure position in which the actuator causes the clutch to operatively connect the camshaft to the rotor. The torque limiting clutch limits torque transfer to the rotor when the engagement clutch operatively connects the camshaft to the rotor. The system also provides control for hysteresis.

An isolating decoupler comprising a shaft having an outer surface, a pulley rotationally engaged about the shaft, a torsion spring having a first section having a major diameter and a second section having a minor diameter, the major diameter is greater than the minor diameter, the torsion spring engaged with the pulley, a wrap spring having an inner diameter less than an outer surface outer diameter, the wrap spring frictionally engaging the outer surface, the torsion spring having an end fixedly connected to the wrap spring, the torsion spring loaded in a winding direction whereby the diameter of each coil of the torsion spring decreases in a progressive sequence as a load increases, the second section is disposed radially outboard of the wrap spring such that the second section moves radially inward to clamp the wrap spring during a load condition, and the pulley comprising a member disposed to progressively release the wrap spring from the shaft outer surface upon occurrence of a predetermined load condition.

A rotational coupling includes input and output hubs disposed about a rotational axis and an attachment ring disposed about the axis on one side of the input hub opposite the output hub. A flexible, multi-coil body such as a cable is disposed radially outwardly of the input and output hubs and couples the hubs together for rotation upon rotation of the input hub in one rotational direction. The body has ends coupled to the output hub and attachment ring. A torque limiter includes a torque transmission plate configured to rotate with the input hub and an armature plate fixed against rotation. The torque transmission plate and armature plate are configured to move axially together along the axis of rotation. An electromagnet disposed on one side of the torque limiter opposite the input hub attracts the plates in a second axial direction away from the attachment ring when energized.

A pulley structure may be equipped with an outer rotating body, an inner rotating body, and a coil spring provided between the outer rotating body and the inner rotating body. The coil spring is configured so as to undergo torsional deformation in a diameter-expanding or a diameter-contracting direction, thereby engaging the outer rotating body and the inner rotating body and transmitting torque, and to undergo torsional deformation in the direction opposite the direction in which torque is transmitted, thereby entering a disengaged state in which the coil spring slides with the outer rotating body or the inner rotating body, thus interrupting the transmission of torque. The number of windings of the coil spring is in a range between [M-0.125] and M (both inclusive), where M is a natural number.
