Definitions

  • the invention relates to a door unit, in particular motor vehicle door unit, with a motion transmission member connected to a door with drive shaft, and with a force applied by the drive shaft coupling member variable clamping force.
  • a door unit of the structure described above is described in the embodiment as a motor vehicle door unit for the motorized actuation of a tailgate as a door leaf in DE 198 44 265 A1.
  • the coupling member variable clamping force serves as a safety coupling.
  • a door unit in which the local coupling member acts as a braking device or blocking mechanism.
  • the locking mechanism is used to lock the hinged door to a vehicle body. This happens for the reason that, for example, during the door opening process, an obstacle appears and the door could collide with the obstacle.
  • the blocking device ensures that a collision between the door leaf and the obstacle is prevented.
  • a door unit is described in the prior art according to DE 10 2009 006946 A1, which is equipped with a biased by a spring friction brake device. The friction brake device dampens door movements. Depending on the path completed by the door, the spring builds up a differently designed braking force.
  • a generic door unit in the invention is characterized in that the coupling member is formed as a function of the rotational speed of the drive shaft releasable slip clutch.
  • the invention thus first of all makes use of a coupling element designed as a sliding clutch.
  • the triggering of the slip clutch is predominantly not dependent on the torque, but in the context of the invention as a function of the rotational speed of the drive shaft.
  • the drive shaft of theoptsübertragungs- member ensures that designed as a slip clutch coupling member is triggered or not.
  • the slip clutch is advantageously equipped with at least one friction element completely or partially enclosing the drive shaft.
  • at least one friction element completely or partially enclosing the drive shaft.
  • two friction elements are realized. This can be attributed to the fact that the drive shaft rotates regularly taking into account two different directions of rotation. These two different directions of rotation correspond on the one hand to an opening movement of the door leaf and on the other hand to a closing movement of the door leaf.

  • the operation of the coupling member or the slip clutch and consequently of the friction element is accompanied by the fact that the friction element is designed to be changeable from its wrap cross section. If the Umschlingungsquer Beatles of the friction element is reduced, so the friction element applies to the drive shaft and encloses this wholly or partially. For this purpose, the engaged position of the coupling member and consequently the slip clutch corresponds. If, however, the friction element is widened by its wrap-around cross-section, then the previously held drive shaft is released and can subsequently rotate more or less freely thereafter. Then the disengaged position of the coupling member and thus the slip clutch and thus the friction element is achieved.
  • the friction element is designed for this purpose as variable in diameter spring.
  • the said spring may be a wrap spring.
  • Such a wrap spring is characterized by a helical course of its spring coils similar to a coil spring.
  • a wrap spring may also have a non-round spring cross-section, but rather is equipped with a rectangular spring cross-section.
  • the broad side of the rectangular spring cross section of the enclosed by the wrap spring drive shaft are facing.
  • the highest possible frictional forces between wrap spring and friction element and drive shaft can be transmitted.
  • the friction element is designed changeable from its Umschlingungsquerites ago and adapted otherwise to the drive shaft.
  • the drive shaft is usually designed cylindrical, the friction element has logically an arcuate or circular character, so that the described Umschlingungs cross-sectional change is usually accompanied by a change in diameter of the friction element.
  • an adjusting element is usually provided, which interacts with the friction element.
  • the actuator is connected to the Antnebswelle. Consequently, the drive shaft controls the friction element via the adjusting element. Depending on the rotational speed of the drive shaft, the friction element is acted upon by the adjusting element more or less. D. h., The actuator interacts with the friction element, in accordance with the rotational speed of the drive shaft.
  • a friction element corresponds to a direction of rotation of the drive shaft. Since the friction element is usually designed as a variable in diameter spring, it is usually worked in this case with two friction elements designed as springs. To illustrate the different directions of rotation of the drive shaft and their consideration, the two said springs are usually equipped with opposing turns. In this way, a spring interacts with a direction of rotation of the drive shaft, whereas the other spring interacts with the other direction of rotation of the drive shaft.
  • the actuator carries these two different directions of rotation account for the fact that the actuator connected to the actuator depending on the direction of rotation of the drive shaft acts either one friction element or the other friction element.
  • the interpretation is usually made such that the actuator after exceeding a predetermined rotational speed of the drive shaft releases the friction element of the drive shaft. If the predetermined rotational speed is exceeded, the actuating element applies the friction element to the drive shaft.
  • the actuator is equipped with an eccentric or the like actuator. With the help of this actuator, the Umschlingungsquerites the friction element can be changed.
  • the design is usually made so that the actuator acts in two directions, namely the following direction of rotation of the drive shaft. In this way, one and the same actuator can change both the friction element for the one direction of rotation and the friction element for the other direction of rotation in its Umschlingungsquerexcellent as desired.
  • the actuating element usually engages at one end of the friction element.
  • the other end of the friction element is held in contrast. Since it is advantageous in the friction element is a spring, the actuator engages at one end of the spring, while the other end of the spring undergoes a fixation. If you work with two springs, one spring per direction of rotation of the drive shaft, the interpretation is made such that the respective free ends of the springs are adjacent to each other. In this way, one and the same actuator can be used to act on the two free spring ends.
  • the actuator is usually a rotatable shaft or rod, which is usually equipped with a damping element.
  • the rotatable shaft or rod usually dips into the damping element in question.
  • the damping element is advantageously equipped with a chamber which is filled with a viscous medium.
  • the actuator is connected to the chamber.
  • the actuator may be an eccentric or else
  • the actuator is directly or indirectly driven and acted upon by the drive shaft. As soon as the drive shaft rotates, the actuator also normally undergoes a rotation.
  • the rotational speed of the actuating element or its movements are damped by the damping element. From a certain rotational speed of the control element, the control element enclosing or receiving chamber is deflected with the actuator connected thereto. Then, the predetermined rotational speed of the drive shaft is reached, which corresponds to the fact that the friction element is released from the drive shaft.
  • the deflected actuator in turn ensures that the free end of the spring is acted upon. Since the free end of the opposite end of the spring is fixed, the application of the free end of the spring ensures that the spring undergoes the desired diameter extension. As a result, the previously held drive shaft is released and can rotate immediately and almost without resistance. In this way, the slip clutch can be triggered in response to the rotational speed of the drive shaft. Once the said rotational speed is exceeded, the actuator can no longer act on the chamber and with her the connected actuator in the sense of rotation, so that the free end of the spring experiences no deflection. The spring contracts and attaches itself to the drive shaft, which is subsequently blocked.
