Abstract:
Disclosed is a driving device for passage gates or thoroughfare gates and door or gate drives. Said driving device comprises a brushless DC servo motor to which a servo regulator is assigned. The output shaft of said DC servo motor is directly connected to the drive shaft of the locking element. The DC servo motor can be accurately regulated to a great extent regarding rotational speed, torque, etc. and can be adapted to different requirements via the servo regulator such that the same motor can be used for many different applications along with said servo regulator, i.e. a continuous drive system is created. Coupling gears and reduction gears, i.e. parts that are prone to malfunction and wear, can be dispensed with due to the fact that the locking element is directly driven, thus requiring less maintenance work at greater intervals.
Abstract:
A driving apparatus for a movable member of an automobile comprises a housing, a drum for driving the movable member, the drum being rotatably supported on the housing, and a clutch for selectively transmitting a driving torque to the drum, wherein the clutch is accommodated in a space of the drum.
Abstract:
An electromagnetic frictionally engaged clutch for arranging inside a drive train connecting a drive motor and a vehicle door or flap. The arrangement ensures that the vehicle door is securely held in each intermediate position, when the clutch is in an idle state, while maintaining the possibility of a manual emergency actuation of the vehicle door. The rotor includes at least one permanent magnet in addition to the electric coil, such that when a current does not pass through the coil, the armature disk is pressed against the friction lining of the rotor, with a force which is strong enough for the vehicle door or vehicle flap to securely remain in position occupied when the clutch is an idle state, and for the friction engagement between the armature disk and the friction lining to be overcome when the vehicle door or vehicle flap is subsequently manually actuated.
Abstract:
Embodiments of the present invention provide power drives comprising a drive unit, a drive cable, a trolley, and a track on which a trolley is guided for moving components for use in motor vehicle applications. The drive unit comprises a gear powered by an electric motor. The electric motor rotates the gear that meshes with and advances the drive cable. The drive unit is coupled to an end of the track by an intermediate cable sleeve comprising a flexible material allowing for independent placement of the drive unit and the track by selectively bending the intermediate cable sleeve. The drive cable passes through the intermediate cable sleeve and is coupled to the trolley and is adapted to advance the trolley along the track. The electric motor causes the gear to rotate in a forward or reverse direction to advance the trolley along the track.
Abstract:
A clutch mechanism of the present power device comprises a fixed gear member, a moving gear member engaged with the fixed gear member when moving to a clutch connecting position, an armature for moving the moving gear member to the clutch connecting position when rotated relatively to the moving gear member, an electromagnetic coil unit for applying a brake resistance to the armature, and a clutch holding surface for abutting against the moving gear member when the electromagnetic coil unit is turned off in the clutch connecting state and for holding the moving gear member at a brake-clutch connecting position. The abutment of the moving gear member against the clutch holding surface is released by rotating the moving gear member relatively to the armature in a state in which the electromagnetic coil unit is operated.
Abstract:
In a door opening/closing device, a rotation sensor is provided at an end of a rotation shaft that is arranged around a clutch. The rotation sensor includes a detecting element that is arranged so as to detect magnetic flux that is generated from the magnetic member in a direction crossing magnetic flux that is generated from an electromagnetic clutch. The rotation sensor is arranged such that an end of the rotation shaft extends outside of a motor base.
Abstract:
The invention relates to an apparatus (1) for opening and closing a door (2) which is arranged so that it can slide on a vehicle (3). The apparatus comprises an engaging element (5), such as a cable, connected to the door (2), and a drive wheel (6) designed to act upon the engaging element (5). A transmission (7) is operatively connected to the drive wheel (6) and the transmission (7) is designed to transmit power to the drive wheel (6) via at least a first gear and a second gear. In one embodiment the transmission may have a neutral position so that the drive wheel (6) can rotate freely. A position sensor (8) is connected to the sliding door (2) in order to detect when the sliding door (2) has reached a predetermined position in the door opening. The transmission (7) then changes gear from the first gear to the second gear. The invention also relates to a vehicle provided with the apparatus according to the invention and to a method of fitting the apparatus according to the invention to a vehicle.
Abstract:
A ratchet hinge for a knee or elbow orthosis having a pair of struts, connected to one strut is a pair of plates in spaced relation to one another. The other strut is pivotably connected between the plates and has a slot formed therein for receiving a locking assembly. The plates have a plurality of ratchets on their outer periphery and a locking slot formed in the edge of the plates. The locking assembly has a spring biased locking pin disposed between two plates such that the pin engages the plates to lock the hinge or allow limited movement.
