Abstract:
A stop member for an operator chain in a chain operator, wherein the operator chain has a width, rivet holes and rivets, constitutes a pin arranged in a rivet hole not occupied by a rivet in the operator chain, wherein the pin has a length exceeding the width of the operator chain. The pin can be cylindrical with a diameter corresponding essentially to that of the rivet hole, and the diameter of the pin can be slightly smaller than that of the rivet hole, so as to be loosely held in the rivet hole.
Abstract:
The object of the invention is a drive system for a motor vehicle door (1), in particular a sliding door (1). This comprises a drive motor (4) and a connected drive means (6, 7, 8, 9) for moving the motor vehicle door (1) along an opening/closing path (R). According to the invention, a gear (5) or generally a torque converter is provided between the drive motor (4) and the drive means (6, 7, 8, 9), said gear or torque converter acting with different torques on the drive means (6, 7, 8, 9) depending on a respective load and/or signal.
Abstract:
A drive for pivoting a flap on a body of a vehicle about a pivot axis, with a drive motor, by means of which an output driving the flap pivotably can be driven rotatably via a drive train having an epicyclic gear. The epicyclic gear has a sun gear, an internally toothed rim, a planet gear which is in engagement with the sun gear and the internally toothed rim, and a planet carrier which carries the planet gear and which is connected fixedly in terms of rotation to a shaft coaxial with respect to the axis of rotation of the planet carrier. The rotational movement of a component of the epicyclic gear can be braked by a brake. In particular, the brake can stop the rotational movement of the internally toothed rim, the sun gear can be driven rotatably by the drive motor, and the shaft of the planet carrier can form the output.
Abstract:
A powered trunk closure assembly for a vehicle includes a linkage assembly attached at one end to a body bracket and at another end to a closure member bracket. A motor is linked with a gear train for actuating the linkage assembly. The motor and gear train are positioned exterior of the trunk.
Abstract:
A driving unit especially adapted to adjusting devices for motor vehicles having an electric motor, a gear box and an electronic control device. At least one element of the electric motor, for example, at the driving shaft, the magnetic short-circuit or the motor side crankcase casing, additionally provides a gear box mechanical feature and/or a mechanical member, for example, a gear box side crankcase casing, provides an electric motor or electronic control device feature.
Abstract:
The invention relates to a drive unit for automatically actuating a vehicle door, in particular the tailgate of a motor vehicle, it being possible to connect the drive unit (4) to the vehicle door (1) or to a transmission device (6) by means of an output shaft (5), said transmission device executing a pivoting movement which corresponds to the pivoting movement of the vehicle door (1), and the drive unit (4) comprising at least one first sensor device (7) which can be connected to an electronic evaluation device (21) and serves to detect the respective angular position of the vehicle door (1). In order to make use of the advantages of an incrementally operating position measurement system of the vehicle door (1), in which, however, recalibration is necessary not only after the end positions of the vehicle door (1) are reached following a power cut, the invention proposes dividing the entire pivot angle (α) of the vehicle door (1) into at least three successive zones (pivot angle ranges) (α1-α4), it being possible to determine the individual pivot angle ranges (α1-α4) by means of a first sensor device (7) which is suitable for detecting absolute values. The pivot angle of the vehicle door within the individual zones (α1-α4) is then detected with the aid of a second sensor device (8) which comprises at least one incrementally operating measured value detector.
Abstract:
An electromechanical strut using an inline motor coupled to an inline planetary gear that are both mounted in the lower housing. The motor-gear assembly drives a worm gear and nut screw in the upper housing, extending or retracting an extensible shaft. Additionally, a power spring mounted coaxially around the worm gear provides a mechanical counterbalance to the weight of a lift gate on the shaft. As the shaft extends, the power spring uncoils, assisting the motor-gear assembly in raising the lift gate. Retracting the shaft recoils the spring, storing potential energy. Thus, a lower torque motor-gear assembly can be used, reducing the diameter of the lower housing. Preferably, the power spring can also drive the power screw to extend the strut even when the motor-gear assembly is not engaged.
Abstract:
A drive arrangement for a motor vehicle door or hatch which can be moved by a motor with a planet gear and a brake device with a brake. The brake device has a brake drive which is separate from the drive which drives the drive shaft and the brake is able to be moved at least from one of two positions into the other of the two positions by the brake drive. The brake can be an arc-shaped clip pivotally supported by a pivot axle with an inner periphery which is matched to an outer periphery of an element of the planet gear. The brake can be combined with the brake drive as an eddy current brake or can be operated by a further gearing or use of a permanent magnet with which an electromagnet is able to interact.
Abstract:
A servo drive for activating a tailgate of a motor vehicle has a drive, a sun wheel driven by the drive and rotatably mounted on a first axle, and a planetary wheel rotatably mounted on a second axle. The sun wheel engages with the planetary wheel. The first and second axles have ends, are movably arranged at their ends facing away from the drive in a common web, and are spaced apart from one another by a constant distance. The planetary wheel engages in a ring gear segment which is fixedly connected to a bodywork, and an end of the web, which faces the ring gear segment, is movably connected to a connecting rod through a third axle. An end of the connecting rod facing away from the third axle is movably connected, via a fourth axle, to an output element which is connected by an end facing away from the fourth axle to the tailgate.
Abstract:
The reduction of cost, size, and weight of an automatic opening and closing system for a vehicle provided with an electromagnetic clutch is achieved. An electromagnetic clutch is provided between a worm gear mechanism in a drive unit and an output shaft connected to a slide door. The electromagnetic clutch has a clutch coil fixed to inside of a worm wheel and an armature attached to the output shaft so as to be movable in the axial direction. Coil ends of the clutch coil are electrically connected to slip rings fixed to the worm wheel, and contacts connected to an electric power source are slidably brought into contact with the slip rings, and electric power is supplied to the clutch coil through these components. By magnetic attraction force generated by the clutch coil in a conducting state, the armature is attracted and engaged with the worm wheel.
