Abstract:
An automatic opening/closing apparatus for vehicle, which is provided with a tensioner mechanism for applying a predetermined tension to a cable member, is downsized. A case of a driving unit is provided with a tensioner housing, and the tensioner mechanism for applying the predetermined tension to a cable is accommodated in the tensioner housing. The tensioner mechanism includes a pulley holder movably mounted on a guide shaft, and a spring for biasing the pulley holder, wherein a movable pulley is rotatably supported by the pulley holder. The cable drawn in the tensioner housing is wound about the movable pulley so that a direction in which the cable is drawn out from the case is substantially parallel to a direction in which the cable is drawn out from a driving drum, whereby the predetermined tension is applied to the cable by a spring force of the spring.
Abstract:
A motorized operator for moving a barrier, such as an upward acting garage door, between open and closed positions includes a support mounted adjacent one of a pair of barrier guide tracks or along a barrier counterbalance shaft and a drive mechanism mounted on the support and engaged with an elongated flexible member, such as a chain, cable or cog belt. A cog belt, for example, is connected to a drawbar connected to the barrier at one end and the belt is either connected directly to the barrier at the opposite end or to a storage reel supported for rotation on and with a shaft of a barrier counterbalance mechanism. The storage reel may include a spiral groove and be supported on the counterbalance shaft for axial translation to receive and dereel the belt as the barrier is moved between open and closed positions. One or more belt tensioning pulleys may be mounted on the support.
Abstract:
A power slide device includes a first cable connected to a wire drum and moving in a first direction when wound up by the wire drum, a second cable connected to the wire drum and moving in a second direction when wound up by the wire drum, a first tension roller having a first abutting surface abutting against the first cable, and a second tension roller having a second abutting surface abutting against the second cable. The first abutting surface is taken as an inclined surface becoming gradually shorter in diameter toward the first direction, and the second abutting surface is taken as an inclined surface becoming gradually shorter in diameter toward the second direction.
Abstract:
An automation assembly is adapted to be connected to a door system of a motor vehicle. The automation assembly is modular and includes a frame that is fixedly secured to the motor vehicle. A motor is fixedly secured to the frame and adapted to receive power. The motor converts the power into a rotational output force. The motor includes a non-ferrous core. A set of pulleys and rollers are fixedly secured to the frame at predetermined positions to direct the path of a continuous belt. The continuous belt is fixedly secured to the door system such that the motor moves the continuous belt and the door system bidirectionally between an open position and a closed position. Sensors are used to determine the position of the door, the speed thereof and whether the door is being moved manually.
Abstract:
A cable tensioner includes two cams mounted to face each other that pivot about a common spindle. A torsion spring is centered on the spindle. The torsion spring includes a first end in abutment with a first cam and a second end in abutment with a second cam. The torsion spring applies a torque onto each of the cams to reduce an angular distance between the cams when a cable exhibits insufficient tension. The cable tensioner is placed in a window regulator mechanism to simultaneously tension a lower cable and an upper cable of the device. Furthermore, the tension of one cable through the cable tensioner is reversible since the tension of each cable is balanced with the tension of the other cable.
Abstract:
An actuating system includes a driving device fixed to a base part and operatively connected to a movable part. A sensor detects the rotational speed of the movable part at a reference measuring location, and a control system forms a differential of the rotational speed with respect to the time. The formed differential is compared in a comparison unit with a stored differential value which corresponds to a measuring point on a route of movement of the movable part. An obstacle is recognized when there is a difference above a threshold value between the formed differential and the associated stored value.
Abstract:
In a system for automatically opening or closing a sliding door or the like for a vehicle, an undesired clamping of an object between the door and the vehicle body, resulting in increased tension force in the wire moving the door, is sent early and relieved quickly. The wire (4) is solidly secured to the sliding door and wound onto a drum (10) to open or close the door by a motor driving the drum, and two tensioners (11a and 11b) are provided respectively on opposite sides of the drum and between the drum and door. Each sensor has a movable part (19) positioned in accordance with the tension force in the wire passing through the tensioner, sensor plates (20) are provided on the movable parts of the tensioners, and magnetic sensors (21) are provided to detect the moving speeds of the plates. When the moving speeds of the plates are larger than a predetermined value, preset in advance, in cases other than when the door is at a fully closed or fully opened condition, a controller concludes that some object has been clamped between the door and the vehicle body and immediately relieves such clamping.
Abstract:
A vehicle power liftgate cable drive has a cable drive housing. An electric motor with a motor housing and an output shaft is secured to the cable drive housing. A clutch pack with a first clutch driven by the output shaft and a second clutch driven by the first clutch, is mounted in the cable drive housing. One of the clutches in the clutch pack is a one way clutch and the other clutch is an electromechanical clutch. A pinion gear is driven by the second clutch. A driven gear is rotatably journaled on a fixed shaft and driven by the pinion gear. The cable drum is attached to the driven gear. A coil spring has one end fixed to the fixed shaft and its other end attached to the cable drum. The fixed shaft is rotated to preload the coil spring in a direction that tends to wind a cable on the cable drum and then the fixed shaft is fastened to the cable drive housing. A cable is attached to the cable drum and to the liftgate.
Abstract:
