Abstract: Inserted in a hollow drive cylinder, a simple push-pull shaft is connected to a cup, open at one end and having a rigid rim and a transverse rod across the open end of the cup. Captured between the transverse rod and the closed end of the cup is a V-shaped spring. Two hardened steel pins on the outside ends of the V-shaped spring inserted through holes in a drive cylinder are inserted into and retracted out of engagement with openings on an interior surface of a concentrically encircling drive ring in response to expansions and compressions of the spring caused by the rim of the cup moved by the push-pull shaft. The push-pull shaft is moved by a push-pull knob outside the cylinder or cable activating knob remote therefrom. The rigid rim of the cup pushes on the sloping sides of the spring to compress the spring which then disengages the pins from the drive ring.

Abstract: The present invention relates to a limit-torque coupling mechanism with delay restoring function. When the relative coupling portion is forced by torque to reverse the limit-torque coupling mechanism, a delay in the restoring function to reduce noise and frictional loss arising from subsequent relative sliding is accomplished so as to restore coupling during the decrease in torque difference or speed difference. To accomplish the aforesaid function lie in that, the design of the torque coupling mechanism being forcibly reversed includes a return motion damper to produce mechanical friction damping, fluid damping or magnetic damping.

Abstract: A treadle drive system operates comfortably in a standing or seated position with two toe or heel end pivoting treadles. A flexible drive line (chain, cable, belt, etc.) from each treadle drives a pair of forward biased driving rings (having sprockets, pulleys, belt wheels, etc.) concentrically encircling and driving a hollow drive cylinder. Concentrically encircling the cylinder, a driven ring in turn drives a rotating device. A positive engagement clutch between the hollow cylindrical hub and the driven ring allows the driven ring to be engaged or disengaged from the drive cylinder. Opposing holes transversely through the hollow drive cylinder engage pins on outer ends of a V-shaped spring. The pins are normally engaged in mating openings on an interior surface of the driven ring. A push-pull shaft with a cup having a rigid rim pushes against the sloping sides of the spring to disengage the pins from the driven shaft only. Pulling the shaft releases the spring reengaging the pins in the driven shaft.

Abstract: A power steering system for vehicles is disclosed using a stepping motor. The stepping motor is energized for power assist in executing turns and for reducing drag of the servomotor during the return of the dirigible wheels to the straight ahead position. A torque transducer operatively coupled with the steering wheel shaft and the steering gear generates a torque signal corresponding to the torque applied by the driver to the steering wheel. A resilient coupling also providing a range of unresisted lost motion is provided between the stepping motor and the steering gear and a transducer is operatively coupled therewith to develop a signal corresponding to lost motion. The torque signal and the lost motion signal are combined differentially and the resultant signal is used to control stepping of the stepping motor. When the driver applies torque to the steering wheel, the torque signal indicates driver input torque and the lost motion signal indicates the applied servo torque.

Abstract: A freewheeling device (11) for torque transmitting purposes at small numbers of revolutions, e.g. at low driving speeds, has two freewheeling parts (14, 17) connected via locking members (25). The locking members (25) engage apertures (24) of one of the freewheeling part (17) and recess (26) of the other freewheeling part (14). If a certain speed of the two freewheeling parts (14, 17) is exceeded, one freewheeling part (14) may overtake the other freewheeling part (17). Switching is effected via a switching cage (29) loaded by centrifugal masses (33) and which moves a switching element (30) into the released position. A spring (36) ensures the transfer into the locked position. A synchronizing device (38) is provided in order to ensure that a transfer into the locked position takes place only at small speed differentials between the two freewheeling parts (14, 17).

Abstract: A coupling having a coupling hub and a rotatably received coupling sleeve. Locking catches (19)are arranged between these two components to transmit torque. Supporting faces of the locking catches, in the torque transmitting position, are supported on corresponding supporting faces of the coupling hub and coupling sleeve. The locking catches are held in the torque transmitting position by switching rings which, via switching faces, act on corresponding switching faces at the ends of the locking catches. In the case of overloading, the switching ring is axially adjusted against the force of a spring and releases the coupling towards the disengaged position. The coupling slides inwardly as a result of the relative movement on the inclined supporting faces of the coupling sleeve.

Abstract: A universal head for fitting to a machine tool slide comprises a spindle head supporting a spindle and a head carrier interposed between the spindle head and the slide in order to transmit torque from the machine tool drive shaft to the spindle. The carrier is rotatable with respect to the slide and the spindle head is rotatable with respect to the carrier along mutually oblique axes. Ordinarily, relative rotation between the spindle head, carrier and machine tool are prevented by hydraulically-actuated brakes and only the spindle is driven by the drive shaft; however, when it is desired to reorient the spindle axis, rotation of the spindle is prevented while the brakes are selectively released so that drive shaft rotation results in movement of the spindle head.

Abstract: An angular scan drive system is disclosed which permits the range of motion of a scanning mechanism to be selectively extended. The invention includes a mass (typically the scanning assembly) which is pivotally attached to a frame to scan in an oscillatory motion during a normal course of operation. A spring is included for applying a restoring force between the frame and the mass and, in accordance with the teachings of the invention, a mechanism is included for selectively coupling and decoupling the mass and the frame through the spring. In a particular embodiment, for example, the mechanism decouples the spring from the frame and attaches the free (frame) end of the spring to the mass on command during a specified portion of the scan cycle. Thus, both ends of the spring are attached to the mass thereby removing the restoring force of the spring from the assembly.

The shift keys are biased to pivot for a selective gear-coupling operation by coned disk springs (19) which are disposed on the cylindrical extension and between the collar and the projections.The disk springs (19) which do not require an enlargement of the outer diameter of shift collar (14) effect a large biasing force upon shift keys (13) for the gear-coupling operation. Further, the disk springs mounted on the cylindrical extension (18) do not cause, when the collar is shifted, a rubbing engagement with the shaft (10) so that a lightness of the shifting operation is assured.

Abstract: A mechanical coupling for a power steering system and the like having a driven shaft reversibly rotated by a servo-motor in response to either clockwise or counter-clockwise rotation of a drive shaft, with the coupling normally connecting the motor to the driven shaft. In the event of any failure of the motor to rotate the driven shaft synchronously with the drive shaft, as for example, due to an electrical power failure, rotation of the drive shaft causes the coupling to disconnect the motor from the driven shaft in the direction opposite to the torque applied by the drive shaft and simultaneously mechanically couple the drive shaft to the driven shaft for direct drive. During that time, the coupling continues to connect the motor to the driven shaft in the direction of shaft rotation. Hence, the direct drive may be assisted by any remaining motor torque, that is, any available torque which is below the level needed to achieve synchronous motion and which is applied in the direction of rotation.
