Definitions

  • the invention relates to a return device for mounted on an axis of rotation pedals of a motor vehicle with a spring element which is fixed on the one hand to a recording on the pedal and on the other hand to a body-mounted recording.
  • Pedals of a motor vehicle for the actuation of brake, clutch and gas with the generic features are known from the prior art in different embodiments.
  • the spring elements here are usually made of tension springs, which are mounted with one end in a receiving device on the pedal, and the other free end of the body side is hinged to a hook or the like.
  • reset devices equipped with compression springs are also known, in particular in return devices for electronic module units for scanning the gas pedal position and transmitting the data thus determined to downstream modules (e-gas modules).
  • the GB-A-2 349 447 already shows a return device for mounted on a rotation axis pedal of a motor vehicle with a spring element which is fixed on the one hand to a recording on the pedal and on the other hand to a body-mounted recording. Between pedal and body while a spring-loaded friction element is arranged with a friction surface pairing, which consists of corresponding friction surfaces.
  • the friction surfaces are elaborately designed as curves and also builds the arrangement in the direction of travel disadvantageously large
  • Object of the present invention is therefore to develop a return device for pedals of motor vehicles of the generic type so that can be made variable in a structurally simple and cost-effective manner caused by the return springs used hysteresis between the actuation directions of the pedal.
  • a solution is seen to arrange between pedal and body at least one spring-loaded friction element with at least one friction surface pairing, which consists of mutually corresponding friction surfaces.
  • the friction element in conjunction with the friction surfaces designed, for example, as planes or as surfaces with a curved course, ensures an increase in the hysteresis between the actuation direction of the pedal and the latter Restoring movement.
  • the spring detection in conjunction with different helix angles ensures an individual adjustment of Betreliistsgefiihls for the pedal to different requirements.
  • an additional damping of the return movement of the pedal can be brought about by the design according to the invention.
  • the solution according to the invention in this case provides to form the friction element of two adjacent cylindrical sections of different diameters, wherein the cylindrical portion is formed with the smaller diameter as a receptacle receiving a compression spring, and the cylindrical portion of larger diameter at its free, the other Section facing away from the end face has the friction surface.
  • the cylindrical portion of larger diameter may be in the context of the invention, an obliquely cut cylinder, as well as an obliquely cut circular cylinder.
  • the friction element is in the described structural design, if necessary, in a cup-shaped receptacle, which is formed as an integral part of the associated motor vehicle pedal, taken with the friction surface of the friction element corresponding second friction surface is arranged laterally of the pedal, for example on a holding device for said pedal.
  • the helix angle between the plane of friction plane and the plane of rotation of the pedal has a value in the range of 0.5 to 10 degrees.
  • a pedal 1 preferably for the operation of an e-gas module is shown.
  • the pedal 1 is hereby received in a pedal bracket 2 connected to the body of the motor vehicle.
  • the pedal bracket 2 has in the illustrated embodiment, two lateral cheeks 3, 4, which define an elongated slot 5 between them, in which on the one hand, the upper part of the pedal 1 is added.
  • the slot 5 takes a designed as a tension spring spring element 6 for generating restoring forces for the pedal 1.
  • the spring element 6 has at its free ends in each case hooks 7, 8 for articulation of the spring element 6 on the one hand on a pedal-side receptacle 9 and on the other hand on a body-side receptacle 10.
  • the spring element 6 Upon rotation of the pedal 1 about a located between the cheeks 3 and 4 axis of rotation 11th (see Figure 2), the spring element 6 is elongated and pulls by its spring action the pedal 1 after completion of the deflection movement in its starting position.
  • the restoring device shown is equipped with a spring-loaded friction element 12.
  • the friction element 12 is arranged in the embodiment shown between the pedal 1 and the cheek 3, wherein the spring 19 (see Figure 2 or 3) of the friction element 12 as a compression spring generates frictional forces in a friction surface pairing with the associated friction surfaces 13 and 14.
  • the friction surface 13 is present on the outside of a cylindrical portion 17 of the friction element 12.
  • the associated friction surface 14 is formed on the inside of the cheek 3.
  • the friction surface 14 forms a bevel (see FIG. 3), which encloses an acute angle ⁇ with the plane of rotation 16, which is shown by dash-dotted lines to clarify its position in FIG.
  • the structure of the friction element 12 is shown (but without friction surface 14) for clarity in the figure 2.
  • the friction element 12 has cylindrical sections 17 and 18.
  • the cylindrical portion 18 in this case has a smaller diameter than the adjacent portion 17, at the portion 18 facing away from the free end, the friction surface 13 is located.
  • the cylindrical portion 18 serves to receive a compression spring 19 which is supported on the one hand on an end face of the cylindrical portion 17 and on the other hand at the bottom of a receiving bore 20 which is placed in the upper region of the pedal 1 adjacent the receptacle 9 for the spring element 6 in the pedal body , wherein the receiving bore 20 is formed in a cup-shaped thickening of the pedal body.
  • this compression spring 19 may be provided in the friction element in different configuration and rigidity.
  • the design of the inclined friction surface 14 makes it possible to make the pedal feel correspondingly variable by increasing or decreasing the friction forces during the pivoting of the pedal.
  • the friction surface 13 on the friction element 12 is adapted in its skew to the friction surface 14.
  • Another variation of the friction surface properties is the choice of Friction pairing, that is, in the choice of materials of the surfaces in contact with each other.
