Abstract:
Under a method to control a sliding speed in accordance with this invention, the motor is initially accelerated for a predetermined reference speed, and then during the initial acceleration period, if a rotational speed of the wire drum is of and above a given value, a difference between a rotational speed of the wire drum and a rotational speed of the motor is of and above a given value, and a rate of acceleration of the wire drum is of and above a given value, the rotational speed of the motor is reduced temporarily judging the slide door is in a state of abnormal acceleration, and then the motor is accelerated again at a lower rate than the initial acceleration toward the reference speed.
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:
The present powered sliding device includes a wire drum (16) connected to a vehicle sliding door (11) through wire cables (18, 19), a motor (14) for rotating the wire drum, a clutch mechanism (25) provided between the motor and the wire drum, a first rotational member (85) rotated integrally with the wire drum, first detection means (86) for detecting the rotation of the first rotational member, and a housing (74). The housing includes a first space (76) accommodating the wired drum and communicating with the outside of the housing through the wire cables and a second space accommodating the first rotational member and the first detection means, and a housing body (73) provided between the first space and the second space for zoning the first space and the second space.
Abstract:
An unlock mechanism for a rotary door operator of a transit vehicle includes a pivotally disposed unlock member adapted for rotating a lock member into an unlock position and activating a valve for discharging the fluid pressure from the drive cylinder to enable manual opening of the door. A spring is provided for biasing the unlock member to a non-activated position. The unlock member may be activated either with a cable or a lever handle. A lock sensing switch provides a feedback on the lock condition to the transit vehicle control system. Additionally, a guiding bracket is provided for securing the cable in proximity of the unlock member.
Abstract:
Gear unit and a motor-driven gear unit for cable window lift systems of motor vehicles, including drive and gear mechanism which cooperates with the drive and is coupled to rotatably mounted cable drum for winding and unwinding cable of the cable window lift system. According to the invention a diameter of the cable drum of the gear unit or motor-driven gear unit is in a range from about 22 mm to about 30 mm, wherein a gear ratio of the gear mechanism ranges from about 1:38 to about 1:55. A cable drum has, on its end side, claws which engage in correspondingly designed recesses on the end side of a worm wheel. Electric motors having a maximum driving torque of only about 5.7 Nm can be used. Overall, the size of the gear unit or motor-driven gear unit can be reduced by about 40-50%.
Abstract:
A tensioner for a cable includes a fixing point and a free end. A first active part defines a first surface of the tensioner, and a second active part defines a second surface of the tensioner which is different from the first surface. The tensioner tensions the cable while following the displacement of the cable. One of the active parts acts as a tensioner on the cable, and the other of the active parts allows the free end of the cable tensioner to follow displacement of the cable, preventing the twisting of the tensioner or deformation of the cable. The tensioner can be employed with cable-driven window regulator for a vehicle.
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:
An opening-and-closing device opens and closes a sliding door by using a cable connected to the sliding door movably attached to a vehicle body. The opening-and-closing device has a base bracket, a motor, a transmission, a rotary drum, a first conduit fixed portion, a second conduit fixed portion, a first tension controller and a second tension controller. The base bracket is fixed to the vehicle body with bolts. The motor, the transmission, the rotary drum, the first and second conduit fixed portions and the first and second tension controllers are fixed to a disposition face of the base bracket. The first and second tension controllers are respectively disposed between the rotary drum and the first conduit fixed portion and between the rotary drum and the second conduit fixed portion, and applies tension to the cable fed from the rotary drum to take up the slack.
Abstract:
This window regulator is constituted by a rail which is obtained in a single piece, by injection of a light-weight metallic alloy, integrating a great many of the window regulator components, like for example: the supports (1) for fastening the window regulator to the door of the vehicle, the support (2) and anchoring elements (6) for the drive motor used in the systems of electric window regulators, the coupling elements (5) of the Bowden system for tensioning the cable (4), necessary in the manually operated systems, the housing (8) for the cable-winding drum, the sliding or diverting elements (3) of the cable (4). Moreover, the rail leaves the mould, with an appropriate curvature for correctly following the window. glass, even though the latter has a very complex shape. Thus, the same rail can be used indistinctly for manual window regulators, electric window regulators and dual rail window regulators.
Abstract:
A window regulator, e.g., for a vehicle window, which includes opposing block and pulley arrangements that interact via a lift pulley (36) mounted to a lift plate (16) that slides along a rail (22). Operative movement of a crank assembly (44) in a first sense tensions a cable (32a) to move the lift plate (16) toward a first end (34a) of the rail (22), and operative movement of the crank assembly (44) in a second sense, opposite the first sense, tensions a cable (32b) to move the lift plate (16) towards a second end (34b) of the rail (22). The regulator enables the reduction of the operating torque requirements without effecting the packaging of the crank assembly.
