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:
An operating mechanism for an open/close object comprising a driving device for driving and opening the open/close object, a position detecting device for detecting an open position of the open/close object (1), and a fully open position storage device for storing a fully open position of the open/close object, wherein, when the driving device drives and opens the open/close object, the driving device is stopped in a fully open recognition position stored in the fully open position storage device or a position a fixed amount short of the fully open recognition position. When a current position of the open/close object after completion of the opening drive by the driving device is different from the fully open recognition position (#1), the fully open position storage device sets a new fully open recognition position (#2).
Abstract:
A locking arrangement for a door system of a transit vehicle includes a combination of a lock mechanism and an electromagnetic brake. The lock mechanism enables positive locking of at least one door but does not require substantial contact between moving and stationary lock elements. The lock mechanism is connected with the manual release means for door opening during an emergency. The electromagnetic brake maintains door seal compression in the closed and locked condition which improves sealing capabilities and provides for reliable lock mechanism operation. Such combination provides locking redundancy and meets various requirements regarding annunciation and manual release operation.
Abstract:
A display tilting apparatus includes a moving bracket that supports a display, a ratchet mechanism that controls pivoting of the moving bracket to a first direction, an anti-tilting mechanism that inhibits pivoting of the moving bracket to a second direction that is opposite of the first direction, and a fixed bracket that is pivotably connected to the moving bracket via a pivot axis. The anti-tilting mechanism includes a first anti-tilting member, and a second anti-tilting member that is mounted on the fixed bracket. The first anti-tilting member and the second anti-tilting member are mounted so as to make a physical contact to each other.
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:
A cable drive assembly for opening and closing a sliding vehicle door has first and second drums that are drivingly connected to each other via a tension spring that biases the drums in opposite directions. The drums include a catch that holds the first and second drums in a cocked condition where the spring is tensioned to provide slack in a closed loop cable to facilitate inserting a traveler attached to the cable into a track. The cocked drums are manually rotated in a drum housing in one direction to move the traveler and insert it into the track. After the traveler is inserted, the cocked drums are manually rotated in the opposite direction. This releases the catch so that the tensioned spring takes up the slack in the closed loop cable.
Abstract:
An opening and closing control system for an opening-closing member comprises an opening and closing mechanism for opening and closing the opening-closing member, an actuator for operating the opening and closing mechanism, an electromagnetic clutch for controlling a torque transmission by connecting and disconnecting the actuator and the mechanism, an opening and closing angle detecting means for detecting an opening and a closing angle of the opening-closing member relative to the vehicle, and a control means for controlling an electric power supplied to the electromagnetic clutch based on a detected result from the opening and closing angle detecting means and controlling an electric power supplied to the actuator, in which a supporting force required for supporting the opening-closing member is increased, and the control means for decreasing the electric power supplied to the electromagnetic clutch in accordance the opening-closing operation from an intermediate position to an opened position or a closed position.
Abstract:
A modular drive assembly for a sliding door, comprising: a guide track having a hinge slidably received therein; a pair of pulleys disposed on either end of the guide track; a pair of cables each having an end that is secured to the hinge and the other end is secured to a cable drum of a motor drive unit mounted to the guide track, the motor drive unit being configured to rotate the cable drum, wherein the cable drum is also capable of freely rotating within the motor drive unit when the motor drive unit is not rotating the cable drum, wherein rotation of the cable drum causes the hinge to move in the guide track as one of the cables wraps onto the cable drum while the other one of the cables wraps off of the cable drum.
Abstract:
A power drive assembly moves a liftgate (12) of a motor vehicle (10) between its open and closed positions. The motor vehicle (10) defines an opening and the liftgate (12) closes the opening when the liftgate (12) is in its closed position. The power drive assembly (22) includes a base (24) that is fixedly secured to the motor vehicle (10) at a position in spaced relation to the opening. A drive mechanism (38) is fixedly secured to the guide. The drive mechanism (38) converts electrical energy into a linear force. The power drive assembly (22) includes a translation linkage (58) connected to the drive mechanism (38) for receiving the linear force and translating it into a nonlinear force to move the liftgate (12) between the open position and the closed position. A nut (52), secured to the translation linkage (58), moves the translation linkage (58) as it travels along a lead screw (50) that is rotated by a motor (40).
Abstract:
A cable drive unit for opening and closing a sliding door on a vehicle (not shown) has a cup-shaped front drum having a helical front cable groove and a rear cup-shaped drum having a helical rear cable groove. The front drum is rotated about a longitudinal axis in a first direction to open the sliding door. The rear drum is partially nested in the front drum and rotated about the longitudinal axis in an opposite direction to close the sliding door. The front drum and the rear drum are drivingly connected to each other via a tension spring that biases the front drum and the rear drum in opposite directions when in tension. The front and rear drums are rotated by a concentric clutch that is nested in the rear drum. The clutch includes a drive member that is drivingly connected to the front drum via a first lost motion connection and drivingly connected to the rear drum via a second lost motion connection. The first drum has an arcuate slot forming part of the first lost motion connection, the rear drum has an arcuate slot forming part of the second lost motion connection, and the drive member has a tab that projects through both arcuate slots to form part of the first lost motion connection and part of the second lost motion connection.
