Magnetic biasing apparatus

摘要

A drive train is used at least including an input shaft and an output shaft. A clutch member is rotatable by a clutch shaft about an axis of rotation. The clutch shaft is supported for lateral movement along the axis of rotation to move the clutch member to cooperate with the drive train at a first lateral position to cause the output shaft to turn and to move the clutch member to a second lateral position to disengage the output shaft from rotation of the input shaft. A permanent magnet is supported by one end of the clutch shaft and arranged for receiving an external magnetic biasing force along the axis of rotation to selectively move the clutch member between the first and second lateral positions. A traveling shaft can be used to support a selected gear for movement by the permanent magnet to implement transmission and reversing configurations.

主权项

1. A magnetic biasing apparatus, comprising:
a permanent magnet that generates a magnetic field from opposing north and south poles to produce an external magnetic field and said permanent magnet is supported for movement to subject an external component to the magnetic field with the north and south poles in a first orientation having a selected one of the north and south poles nearer to the external component and to subject the external component to the magnetic field with the north and south poles in a second, reversed orientation having the other one of the north and south poles nearer to the external component; and a magnet housing supported for rotation about an elongation axis thereof and the magnet housing defines a through passage that is transverse to the elongation axis for receiving said permanent magnet for rotation by the magnet housing to selectively provide said first orientation and said second orientation.
