Definitions

  • the invention relates to an outside door handle, in particular for vehicles "referred to in the preamble of claim 1.
  • Such exterior door handles are nowadays used in almost every door of every vehicle, especially in automobiles.
  • both the handle and the conversion element have actuating surfaces which cooperate in the actuation case in order to transmit the movement of the handle to the conversion element.
  • an approximately cylindrical pin is provided on the conversion element while the handle is about an approximately circular. or circular segment-shaped element.
  • the inner radius of this element represents the first actuating surface, while the second actuating surface is formed by the outer side of the cylindrical pin.
  • a disadvantage of this known arrangement is that the transmission ratio between the two components varies. Even at low manufacturing tolerances can occur as strong fluctuations in the operating force. The power losses occurring due to the friction of the two actuating surfaces are also very different. An operator, who operates the handle to open the door, thus often experiences a hook of the handle and must apply very different forces during the operation, so that again and again sections occur where on the one hand the operation is easy to carry out and spent little force and on the other hand there are sections where a stronger force is required to operate the handle. This is uncomfortable for the operator. In addition, the production of components is significantly more expensive, since very narrow tolerance ranges must be met.
  • the object of the invention is therefore to improve an outside door handle of the type mentioned above so that the forces required for the operation of the handle are as uniform as possible and the production can be carried out more cost-effectively, since the components are not so sensitive to tolerances.
  • This object is solved by the characterizing features of claim 1, which have the following special significance.
  • the actuating surfaces are in the form of parts of cycloids or parts of involutes. Due to this special shape, the handle and the conversion element have a constant transmission ratio over the entire actuation process. Also the power loss through between the Actuating surfaces occurring sliding friction is more constant. As a result, the operation of the handle is more comfortable and comfortable for an operator. Furthermore, the actuating surfaces and thus also the handle and the conversion element are less sensitive to manufacturing tolerances. This is the case in particular when using actuating surfaces in the form of involute parts. The production can be carried out more cheaply. In one particular embodiment, one actuating surface is in the form of part of an epicycloid and the other actuating surface is in the form of a part of a hypocycloid. It is irrelevant which of the two actuating surfaces which form.
  • both actuating surfaces in the form of involutes, in particular of circle involutes. This makes the components particularly insensitive to manufacturing and assembly tolerances.

  • Figures 1 and 2 show a handle according to the invention in a preferred embodiment.
  • This handle is intended for a folding handle.

Furthermore, one recognizes the connection point 22 for a transmission element not shown here in detail.
  • This transfer member serves to transmit the movement performed by the handle 10 during operation by means of the two actuating surfaces 11, 21 and the conversion element 20 via the transfer member to the lock located on the door 30.

  • FIG. 6 now shows the construction or construction of an epicycloid E.
  • This can be described by a point P, which moves with it when the rolling circle K rolls on the outer circumference of the guide circle L.
  • the point P can, as shown in FIG. 6, lie directly on the circumference of the rolling circle K, but also at any point inside or outside the rolling circle K.

  • the point P which describes the epicycloid E, is located a distance ⁇ a far from the center M of the pitch circle K.
  • the distance between the center M of the pitch circle K and the point P exactly the radius a of the pitch circle K, since the Point P is located directly on the circumference of the pitch circle K.
  • the angle ⁇ is formed between the positive x-axis and abscissa and a straight line through the origin O of the coordinate system and the center M of the pitch circle K. The angle ⁇ thus changes with the rolling of the rolling circle K on the outer circumference of the circuit L.

  • the distance between the center M of the pitch circle K and the point Q, which describes the hypocycloids, is ⁇ a.
  • the point Q lies exactly on the circumference of the pitch circle K, so that the distance ⁇ a is equal to the radius a of the pitch circle K.
  • the angle ⁇ describes the angle between the positive x-axis or abscissa and a straight line, which is defined by the zero point O of the coordinate system and the center M of the pitch circle K. The angle ⁇ thus changes during the rolling of the rolling circle K on the inner circumference of the circuit L.

  • the zero point O of the coordinate system is located in the center of the output circle Z with radius r.
  • the angle ⁇ is formed by the positive abscissa or x-axis and a straight line through the center O of the output circle Z and the point T at which the tangent is applied to the output circle Z at this time.
  • the angle ⁇ thus changes while the point T on the circumference of the output circle Z wanders along and so the involute V is formed.
  • the radius r of the output circle Z is less than or equal to 200 mm.
  • the two output circuits Z of the circle-involute parts of the actuating surfaces 11, 21 have different radii r.

Abstract

L’invention concerne une poignée extérieure de portière, en particulier pour véhicules. Cette dernière présente un élément d’actionnement qui, une fois actionné, peut servir à ouvrir la portière et qui dispose d’une première surface d’actionnement. En outre, la poignée présente un élément de déplacement, tel qu’un levier, qui présente une seconde surface d’actionnement. Lorsque l’élément d’actionnement est actionné, les deux surfaces d’actionnement sont amenées à coopérer l’une avec l’autre, l’actionnement de l’élément d’actionnement entraînant le mouvement de l’élément de déplacement. Selon l’invention, les deux surfaces d’actionnement sont réalisées sous la forme de parties de cycloïdes et de parties de développantes.
