Abstract: A control apparatus of a remote type free wheel hub clutch includes an inner sleeve integrally rotatable with a wheel axle, a clutch ring integrally rotatable with the free wheel hub clutch, an actuating arrangement for changing the two-wheel and four-wheel driving operations by engaging or disengaging the clutch ring with the inner sleeve in response to a transfer shift position. The transfer shift position actuates a discriminating circuit for changing over from two-wheel driving operation to four-wheel driving operation or vice verse.

Abstract: An electrically actuated free wheel hub apparatus includes an axle tube, a wheel hub arranged about the axle tube and operated in response to the position of a drive transfer mechanism. An electric motor is disposed in a body fixed to the wheel hub and an axle shaft is interior to the axle tube. A control device control transmittal of power between the axle shaft and the wheel hub by a clutch mechanism. A syncromesh device is provided in the drive transfer mechanism so that each rotation of a front wheel side and a rear wheel side can be synchronized and a delay device transmit current to the motor after the completion of synchronizing.

Abstract: In an electric control apparatus for a clutch mechanism provided therein with a reversible electric motor which is activated under control of a changeover switch to engage the clutch mechanism in its forward rotation and to disengage the clutch mechanism in its reverse rotation, a first period of time is set when the changeover switch has been operated to engage the clutch mechanism, and a second period of time is set when the changeover switch has been operated to disengage the clutch mechanism. The first period of time represents a power supply time during which the electric motor is activated to cause full engagement of the clutch mechanism. The second period of time is defined to be longer than the first period of time and represents a power supply time during which the electric motor is activated to cause full disengagement of the clutch mechanism.

Abstract: A free wheel hub system comprises a free wheel hub mechanism disposed between a drive shaft and an axle hub supported by a spindle, an electric motor mounted on a hub body accommodating the free wheel hub mechanism, a brush case mounted on the hub body and accommodating bushes connected to the electric motor, and slip-rings mounted on the spindle and contacting the bushes. The brush case is fixed to the hub body before the hub body is attached to the axle hub.

Abstract: A control device of a remote free wheel hub mechanism includes a free wheel hub mechanism, an actuator and a control circuit. The control circuit further includes a two-wheel-drive circuit, a four-wheel-drive circuit, a transfer shift position detecting sensor, and an engine rotation drive detecting sensor. One of the two-wheel-drive circuit and the four-wheel-drive circuit in the transfer shift position detecting sensor moves to a closed condition independently of the shift position when the engine is stopped, and the transfer shift position detecting sensor correspondingly produces a signal of one of the two-wheel-drive and four-wheel-drive conditions, respectively. The engine rotation drive detecting sensor detects a rotational condition of an engine and produces a signal which closes one of the two-wheel-drive and the four-wheel-drive circuits when the engine is stopped.

Abstract: Disclosed is a clutch mechanism suitable for use in an electronic lock. The clutch mechanism requires minimum electronic current draw for operation by utilizing mechanical power applied to operate the lock to engage the clutch mechanism. A camming device in combination with a timed function motion sensor and latching solenoid released interference shutter accomplishes the object of the invention.

Abstract: Conversion of a vehicle between two-wheel drive and four-wheel drive is effected by means of a camming assembly and a shift mechanism to temporarily lock the camming assembly against rotation in advancing a drive gear into driving engagement with a receiving gear in converting to four-wheel drive, or to re-engage the camming assembly under the control of the shift mechanism as a preliminary to disengaging the drive gear from the receiving gear in converting to two-wheel drive.

Abstract: An electrically operated wheel hub clutch assembly comprises a cylindrical body of magnetic material integrally formed therein with an internal spline and to be fastened to the outer end of a wheel hub, an inner sleeve member of non-magnetic material fixedly mounted on the outer end of an axle and located within the cylindrical body, a cylindrical clutch member of magnetic material integrally formed with an external spline to be engaged with the internal spline and axially slidably mounted on the sleeve member for rotation therewith; a spring for biasing the clutch member toward an unlocked position in which the external spline is disengaged from the internal spline, an annular core fixedly mounted on the outer end portion of an axle tube and having a cylindrical portion opposed to the inner end portion of the clutch member, and a magnetic coil fixedly coupled over the cylindrical portion of the core and being responsive to an electric control signal to produce an axial attraction force between the clutch mem

Abstract: Disclosed is a clutch mechanism suitable for use in an electronic lock. The clutch mechanism requires minimal electronic current draw for operation by utilizing, in part, mechanical power applied to operate the lock to engage the clutch mechanism. A unique camming device in combination with a solenoid released interference shutter accomplishes the object of the invention.

Abstract: In an electromagnetic spring-wound clutch, an input rotary member is concentrically and rotatably fitted on an output rotary member having an annular enlarged portion, with its axial boss disposed adjacent the above annular enlarged portion. A coil spring is wound around the axial boss and the annular enlarged portion for gripping engagement with at least the former, with its one end engaged by the output rotary member and its other end by a sleeve concentrically and rotatably supported on the input and output rotary members. An armature is disposed for axial tilting about its one edge supported by a stationary member. Responsive to extinction of electromagnetic force caused by deenergization of a magnetic coil, the armature is axially tilted by the force of a spring into engagement with the sleeve to hold same from rotating.

Abstract: A rotatable globe has a drive motor supported by a stationary shaft, the drive motor being positioned entirely within the globe and having switching means actuated by manual rotation of the globe.

Abstract: A four-way pawl clutch has forward and reverse drive pawls pivotally mounted on a cage. The cage carries two indexable phasing rings. One is resiliently coupled to the forward drive pawls by overcenter leaf springs which bias the forward drive pawls toward or away from an engaged position with the clutch drive members depending on the indexed position of the phasing ring. The second phasing ring is resiliently coupled to the reverse drive pawls in a like manner. The two phasing rings may be indexed to provide freewheel, forward drive, reverse drive and lock-up modes of operation. The two phasing rings may be remotely controlled by solenoids or the like. The two phasing rings may also be coupled so that the four-way sprag clutch operates essentially as a two-way dog clutch.

Abstract: Torque is transmitted between the driving and driven members of the clutch by a helical spring and a friction shoe. When an electromagnet is excited, pilot torque is applied to the spring to cause the spring to clamp downwardly around the shoe and cause the shoe to contract radially around the driving member and transmit torque to the driven member. The driving member, the driven member, the spring and the friction shoe are arranged in such a manner that the spring effects soft engagement of the clutch while amplifying the pilot torque sufficiently to enable a relatively small and light weight clutch to produce ample output torque.
