Definitions

  • the invention relates to a pedal, in particular for a Vehicle, with one in a holding part around one Swivel axis pivoted pedal arm, which deflectable by foot force by means of a pedal plate and from at least one return spring element into a Basic position is pivotable, and with a one Friction body and a friction damper comprising a friction surface to create a damping of the movement of the pedal arm, the friction body with the pedal arm connected and against the friction surface by means of the return spring element is biased.
  • the pedal arm usually carries a segment of a circle Friction body, which against a free end of a two-armed lever arranged friction surface. At the same time the pedal arm is by means of a compression spring connected to the other end of the lever. This will the contact pressure between the friction body and the friction surface increasing deflection of the pedal arm larger, so that Attenuation is increased.
  • the pedal required by the described construction a large number of components, which are complex to manufacture and assemble, whereby the space requirement of the arrangement is relatively large at the same time is.
  • the invention is based on the problem of a pedal type mentioned in the beginning so that it is as possible is simple and at the same time low Owns space.
  • the friction body is arranged eccentrically with respect to the pivot axis is. This will increase the friction large deflection around the pivot axis not by the Return spring element, but mainly by the eccentricity of the friction body.
  • the friction body allows almost any shape and one with it connected any movement characteristics of the pedal arm. At the same time it is also possible to move the pedal opposite restoring force due to the shape to design the friction body so that an adaptation to a desired characteristic is possible without this a special return spring element is required.
  • the invention also allows the use of a conventional one Return spring element. Is particularly compact executed the pedal according to the present invention, if the return spring element as a leg spring or Leaf spring is executed. This advantageously eliminates Way the otherwise required lever so that the Friction body directly against the return spring element is directed.
  • the invention is particularly advantageously developed, if the friction body is designed as a cam. This allows the operator to apply Pedal operating force optimally a desired Adjust characteristic.
  • areas the deflection of the pedal arm with a greatly increased Resistance and low resistance areas are infinitely variable combine. For example, progressive areas are shown in which the driver's performance limits of the drive as a greatly increased resistance be reported back.
  • the invention is particularly economical, when the return spring element on its the friction body inclined side is designed as a friction surface.
  • the return spring element on its the friction body inclined side is designed as a friction surface.
  • there is no work step during assembly which makes this version particularly economical.
  • FIG. 1 shows a pedal 1 according to the invention in one lateral, partially sectioned illustration.
  • a pedal arm having a pedal plate 2 3, which is pivotally mounted about a pivot axis 4 and with two friction bodies 5 and 6 designed as cams connected is.
  • the friction bodies 5 and 6 each have a surface section 7, 8, which against a Legs 9, 10 designed as a leg spring 11 Return spring element 12 is present.
  • the leg spring 11 encloses an axis 13, which the fixation of the Leg spring 11 is used.
  • the course of the characteristic curve of the pedal actuation force is essentially from the contours of the Surface sections 7 and 8 of the friction body 5 and 6 determined.
  • FIG. 2 shows a pedal 14 that is slightly modified compared to the pedal 1 shown in FIG. 1.
  • the pedal arm 3, which is only shown in sections, is connected to a one-piece friction body 15.
  • the surface sections 16, 17 of the friction body 15 which are inclined towards the two legs 9, 10 of the leg spring 11 each lie against a section of the legs 9, 10 designed as a friction surface 18, 19.
  • the pedal actuation force F P which is applied by the operator to the pedal arm 3, and the spring force F F , which are respectively applied to the friction body 15 by the two legs 9, 10 of the leg spring 11, are shown schematically in this figure .
  • it is particularly advantageous that the lines of action of the spring force F F respectively applied by the two legs 9, 10 are approximately aligned.
  • the lever ratio which is determined by the distance between the axis 13 and the contact surface between the respective legs 9, 10 and the friction body 15, remains unchanged even with different deflections of the pedal arm 3 about the pivot axis 4. Very little forces therefore act on the axis 13. At the same time, the required pedal actuation force F P can be easily defined as a function of the deflection of the pedal arm 3.
  • FIG. 3 shows a further embodiment of a pedal 20 a conventional return spring element designed as a compression spring 21.
  • the pivotable about the pivot axis 4 and only partially Pedal arm 3 shown a lever arm 22, on the free end of a friction body 23 is arranged.
  • This The friction body 23 lies against a friction surface 24 an axis 25 pivotable lever 26.
  • On that of the axis 25 opposite free end of the lever 26 is that arranged as a compression spring return spring element 21, which is the friction surface arranged on the lever 26 24 presses against the friction body 23.
  • a lever 26 opposite end of the spring element 21 is at one Wall 27 of a pedal housing, not shown supported.
  • the Friction body 23 along the friction surface 24 in the direction of Axis 25 of the lever 26, the lever ratio and thus counteracting a further deflection Force changes.
  • the return spring element 21 itself any, in particular progressive spring characteristic or means for presetting possess the spring force.
