Definitions

  • the invention relates to a stepless, power-operated motor vehicle door arrester, consisting of a rigid door holding member pivotably articulated on a door arrangement part, door or door pillar about an axis parallel to the door hinge axis, and an associated brake or brake element arranged on the other door arrangement part.
  • Locking device and a controllable auxiliary device for actuating the braking or locking device depending on the one hand on the current door opening angle and on the other hand on the current angular velocity of the door and the opening and closing forces acting on the door as well as any other reference values for assessing the movement situation of the door .
  • the invention is therefore based on the object of improving an auxiliary power-operated, controllable door arrester of the type mentioned at the outset in such a way that it can be controlled sensitively with a sufficiently high braking and holding force and small construction and, on the one hand, can be produced with the least possible number of simple components and at the same time also has low weight.
  • This object is essentially achieved in that the braking or. Locking device depending on the door movement, preferably rotating, driven part and at least one interacting with it, drivable braking or. Contains holding part, which can be moved at least in the direction of its operative position by means of at least one auxiliary element acted upon by an auxiliary force.
  • This design of the braking and holding device of a motor vehicle door lock enables not only a relatively small design of the door lock but also sensitive controllability, ie a sensitive, jerk-free application of the brake or. Holding force.
  • the designer is also given extensive freedom of design with regard to the design of the drive and drive transmission element, so that on the one hand he has the appropriate design and design of the drive and drive transmission element and the braking or. Holding part, on the other hand, without the risk of mutual interference, even with high braking and holding forces to be applied, both the sensitivity of the application of the braking or. Holding effect as well as the design of the door arrester can be optimally designed according to the given conditions.
  • a very special advantage of the design of a door arrester according to the invention is further that with a suitable design, braking forces of different magnitudes can be assigned to the two directions of movement of the door without any additional effort, ie without additional parts.
  • the door arrester according to the invention is constructed and designed in the manner of a band brake.
  • the braking or. Holding part is formed by a longitudinal section of a rope or band or a brake member which can be acted upon by the latter, the rope or band being connected at both ends to a drive element formed by a pivoting lever and the brake band or brake cable of the braking or locking device on Outer circumference of a in Depends on the door pivoting movement of a rotationally driven, preferably roller-shaped part, and is adjustable in the tightening direction by means of a pivoting lever.
  • the part of the braking or locking device which is driven in rotation as a function of the door movement is expediently directly or indirectly in meshing engagement with the rigid door holding member, a particularly expedient but not exclusive embodiment being seen in the fact that the rigid door holding member is provided by a threaded spindle and the part of the braking or locking device which is driven in rotation as a function of the door movement is formed by a spindle nut which is rotatably mounted in a fixed housing.
  • This configuration opens up a great variety of possibilities for the designer with regard to the braking and holding forces that can be applied in that either the pitch angle of the threaded spindle is chosen to be greater than the friction angle between the spindle and the spindle nut plus the friction in the axial bearings assigned to it, or the pitch angle of the threaded spindle is chosen to be the same size than the friction angle between the spindle and spindle nut plus the friction in the associated axial bearings.
  • one on the braking or. Holding element acting, rotatable or pivotable drive element instead of a manual drive is assigned depending on the one hand on the current door opening angle and on the other hand on the instantaneous angular speed of the door and the opening or closing forces acting on the door acting motor drive.
  • the motor drive for the pivot lever forming the drive element can be designed as a rotating stepper motor and with one end of the pivot lever forming the drive element interact by means of a cam or eccentric.
  • the motorized, in particular electromotive, drive is designed as a linear motor and interacts directly with one end of the swivel lever forming the drive element.
  • the braking or holding part formed by a longitudinal section of a rope or band engages over the rotatingly driven part of the braking or holding device by means of at least one loop.
  • the rope can be formed by a wire material, depending on the coefficients of friction of the wire or rope on the one hand and the rotatingly driven part of the braking or locking device on the other hand one or two wraps around the rotatingly driven part can be provided.
  • Holding forces can also be the use of a band instead of a rope or wire as a braking or. Recommend holding part.
  • the pivot lever forming the drive transmission member in one direction preferably in the direction of engagement of the brake or. Locking device associated direction of movement is constantly loaded with the load of a compression spring.
  • the braking or. Locking device constantly engaged and the braking or. Locking device is released when the door is intended to be moved by the manual or motor drive, as long as a corresponding actuating force acts on the door.
  • the at least one braking or. Holding part is designed as a brake block or brake shoe overlapped by a longitudinal section of a rope or band and cooperates with the door holding member in a frictionally locking manner.
  • pivot lever is in permanent contact by means of a spring-loaded plunger with an adjusting cam or adjusting center assigned to it, and the pivot lever is pivotably pivoted about an axis parallel to the spindle on a housing supporting the spindle nut, and further the drive the pivot lever is associated with a crank pin driven by an electric motor, which rotates about an axis parallel to the spindle and at the same time also actuates a part of the control device for the door stay forming microswitch indicating the locking or release status of the door stay.
  • the motor vehicle door arrester shown in the exemplary embodiment essentially consists of a rigid door holding member designed as a threaded spindle 2 and pivoted on a door arrangement part, door or door pillar pivotably about an axis 1 parallel to the door hinge axis, and a brake associated therewith and accommodated in a housing 3 arranged on the other door arrangement part -respectively.
  • Locking device comprises a spindle nut 7 which is rotatably mounted in the housing 3 via axial bearings 6 and a braking or braking element formed by a length section 8 of a cable. Holding part and a compression spring 9 loading the swivel lever 5. Holding part forming length section of a rope 8 wraps around the spindle nut 7 and is connected with its two ends 10 and 11 to the pivot lever 5.
  • the braking or. Retaining part of the locking device forming length section 8 of a rope with its one end 10 in a first fastening part 14 arranged in the vertical plane running through the spindle axis and with its other end 11 in a second at a distance from the vertical plane running through the spindle axis attached to the pivot lever 5.
  • the result of the spring load 9 acting on the free end 13 of the swivel lever is that braking torque is exerted over the length section 8 of the rope on the spindle nut 7 until the swivel lever 5 is pivoted into a release position by means of the electric motor against the spring load 9, as a result the fact that the two ends of the length section 8 of the rope are connected to the pivot lever 5 at different distances from the vertical plane running through the spindle axis, the braking torque Md2 exerted on the spindle nut for the one direction of rotation of the spindle nut 7 is greater than the braking torque Md3 for the other direction of rotation of the spindle nut 7.
  • the electric motor 4 interacts with the swivel lever 5 forming the drive element by means of a cam or eccentric 16, a transmission lever 17 contacting the cam or eccentric by means of a spring tappet 18 stands.
