Abstract:
Method of facilitating release of an object caught by one or more closing transit vehicle door(s) in a motorized door system having a two stage lock, the two stage lock having a fully locked position and a pushback lock position. The method includes detecting the presence of the object by the effect of the object on either the position or the velocity of the door(s). The method also includes determining whether the door(s) are in a pushback range between the fully locked position and the pushback lock position. If an object is detected and the door(s) are in the pushback range, then one or more signals are supplied to a motor of the door(s) to move the door(s) in the door opening direction to or toward the pushback lock position.
Abstract:
A power drive moves a movable closure along a fixed path between an open and a closed position with respect to a portal defining a passage through a barrier. The power drive system is adapted for a sliding door mounted on at least one side of a vehicle for sliding movement forwardly and rearwardly of the vehicle. The system includes a reversible motor operable when actuated to selectively drive the door in opening or closing movement. A bracket is connected to the door for movement with respect to a guide connected to the side wall of the vehicle. The bracket is guided within the guide along a fixed path between the opened and closed positions of the door. An elongated drive member is connected to the bracket at one end for driving the bracket along the fixed path. The elongated drive member is slidably disposed within the guide. A translator mechanism operably engages with the drive member for powering movement of the drive member and connected bracket with respect to the guide along the fixed path. The translator mechanism can include a rotatable hub, operably engageable with the drive member, a gear transmission for driving the hub, and a clutch mechanism for connecting the motor to the transmission. The translator mechanism preferably has sufficient power to pull the sliding door into a primary latch position with respect to the corresponding portions of a latch mechanism attached to the door and frame defining the door opening.
Abstract:
A vehicle sliding door opening/closing control device comprises a control unit for outputting a standby signal and shifting into a standby mode when for a predetermined time there has been no user-operation input for causing a vehicle sliding door driven by a motor to be open/close-driven and shifting into an operating mode and performing control of the motor when there has been a user-operation input and a switch unit for shorting power input terminals of the motor on the basis of the standby signal. When there has been no user-operation input for causing the sliding door to be open/close-driven for a predetermined time, by shifting into a standby mode the power consumption of the control unit can be kept small and as a result it is possible to suppress the battery power consumption of the control unit. Also, in the standby mode, by shorting the power input terminals of the motor it is possible to keep the motor in a locked state and thereby apply braking to the sliding door. Therefore, when the vehicle has been stopped or parked on sloping ground such as an upward slope or a downward slope, it is possible to prevent the sliding door from starting to move under its own weight when it is half-open.

A powered sliding device for sliding a vehicle door comprises a base plate, a wire drum rotatably mounted on the base plate by a drum shaft and rotated by a motor, a wire cable for pulling the door in an opening direction or in a closing direction when the wire drum rotates, a tension shaft slidably mounted on the base plate in a given direction and having a tension roller, a movable member slidably mounted on the base plate in a direction perpendicular to the given direction, and a coupling member having one end rotatably connected to the tension shaft and the other end rotatably connected to the movable member. The given direction coincides with a radial direction of the drum shaft. Each side of a contact portion of the wire cable relatively to the tension roller extends straight toward the wire drum.
Abstract:
A powered sliding device for a vehicle sliding door comprises a motor, a wire drum rotated by the motor, a wire cable provided between the wire drum and the sliding door, an optical sensor for outputting a detecting signal when the wire drum rotates, a controller for calculating from the detecting signal at least one of a rotational speed of the wire drum, a rotational amount of the wire drum and a rotational direction of the wire drum, a latch unit provided in the sliding door and engageable with a striker, a power supply switch for supplying electric power to the optical sensor. The power supply switch stops supplying the power to the optical sensor while the door is being closed.
Abstract:
A door closing apparatus facilitates simultaneously opening of a pair of sliding doors by pulling a manual release wire. Specifically, by pulling the manual release wire, a belt 82 fixed to the manual release wire moves with belt pulleys and two hooks to contact and move respective movable frames to the opening directions thereof. Due to these movements, permanent magnets 31A, 31B rotate, through respective racks to release the holding of the closed doors. Thus, the sliding doors can be opened manually.
Abstract:
A clutch selectively transmits torque and rotary motion from a spindle having an axis of rotation to a drum. First and second shoe members disposed radially between the spindle and the drum move radially with respect to the axis of rotation between an engaged position and a disengaged position with respect to the drum. The first and second shoe members are responsive to acceleration for moving into the engaged position and responsive to rotational speed for moving into the disengaged position. A biasing spring normally maintains the first and second shoe members in the disengaged position when the spindle is at rest.
Abstract:
An electromechanically operated door having a control and regulation system for the door, the door for being driven by an electric motor, the movement of the door being controlled by sensors. The control and regulation system is equipped with a microprocessor control. In addition to the normal path of data to the microprocessor control, a dual redundancy is achieved, in that there is a safety monitoring system which receives the same safety-related information as the microprocessor control. This safety monitoring system, for its part, is capable of detecting a fault, i.e. if the microprocessor control system has not shut off the door, the door is shut off by the safety monitoring system, which for its part reports any faults which occur in the system to a fault detection unit, and here again, by means of a redundant shutdown unit, brings the connected motor and thus the door to an immediate stop. In addition to the automatic verification of the safety-related functions, manual verification of the safety functions is also possible. Also contemplated is a control and regulation system, having the above features, for a door.
Abstract:
A brake and clutch assembly mounted on an electric motor's drive shaft comprises, in succession and outwardly from the motor, a brake pad, a drive disk, a clutch plate, a pulley, a compression spring and an end cap. The drive disk includes a sleeve with the clutch plate and the pulley being slidably mounted thereon. A pin extending diametrically through the shaft lies in a diametrical V-shaped recess defined in the drive disk. The spring biases the pulley, clutch plate and disk drive towards the brake pad thereby frictionally retaining the drive disk thereagainst when the motor is not operating and preventing the components from rotating. When the motor is started, the pin climbs out of the bottom of the recess by pushing the drive disk against the spring's force thereby axially displacing slightly the disk drive away from the brake pad such that the pin rotates the drive disk which frictionally drives the clutch plate and the pulley. Resistance applied against the rotation of the pulley causes the clutch plate to slip thereby allowing the pulley to stop while the clutch plate, the drive disk and the motor shaft continue to rotate, thus preventing damage to the motor. The friction forces between the clutch plate and the pulley are insufficient to stop the clutch plate and thus the drive disk and the motor shaft if the pulley is forced to stop rotating.
