Definitions

  • the invention relates to an adjustable Pedal consisting of a pivotable around a pedal axis Push rod lever with an articulated on it Push rod and from a pedal lever on the lower End arranged a pedal plate and the in a Rail is guided on the push rod lever.
  • Pedals are used for actuation in a vehicle the brake and the clutch and as a control element for Power control of the drive motor. You are in one defined position in the footwell of the passenger compartment. It has already been suggested that the pedals be adjustable set up so that the driver's positions adapt to his needs in relation to the seating position can, without bringing the seat too close to the steering wheel to have to.
  • Each of the pedals is made in two parts executed: It consists of a push rod lever, which rotates around a pedal axis and on which an actuator is articulated, and from a pedal lever with a pedal plate that is slidable opposite the push rod lever is arranged. With a shift of the pedal lever compared to the push rod lever changed but not only the position of the pedal plate the passenger compartment but at the same time their relative position to the pedal axis, which is an undesirable change of the gear ratio.
  • the invention has for its object this System to improve further.
  • this System should be achieved be that the gear ratio at a Adjustment remains essentially constant.
  • the pedal should be as simple as possible and one enable electromotive adjustment.
  • the rail guide of the pedal lever is curved, with the center the curvature is arranged so that with an adjustment the pedal plate substantially parallel to Push rod is displaced.
  • the desired curvature is achieved by that the bottom of the U-shaped tab is curved and the pedal lever is curved has this outer edge adjacent to the floor. This Curvature ultimately determines the path of the pedal plate an adjustment. It is therefore taken into account the other structural conditions, such as orientation the push rod and the arrangement of the pedal in the To determine the passenger compartment.
  • the inner edge of the pedal lever with a toothing and in The bracket has a pinion that can be rotated in the toothing of the pedal lever engages.
  • the worm wheel becomes one Worm gear on the pinion in a coaxial arrangement attached, the worm of the worm gear is rotatably mounted on the outside of the tab.
  • a preferred embodiment of the tab exists from two plates that are mirror images of each other.
  • the tab and pedal lever are preferred made of metal. So that the pedal lever has little friction can be adjusted between the pedal lever and arranged the tab sliding body.
  • a push rod lever 2 attached to the lower end a push rod 3 is supported, which for actuating a Brake cylinder or clutch cylinder is used.
  • a rail 4 fixed to the pedal shaft 1 is a rail 4, which are roughly parallel to the push rod 3 and with you are welded.
  • Push rod lever 2 and rail 4 thus form a functional unit.
  • the rail 4 is made of a bent tab with two cheeks 5.5 'and a curved bottom 6 formed.
  • a pedal lever 10 consists of an upper guide part 7 and one adjoining it downwards Holding part 8, at the lower end of a pedal plate 9 is attached.
  • Guide part 7 and holding part 8 form in this version has a flat oval cross section.
  • the Cross section can also be rectangular, as in the Fig. 3 shown.
  • the pedal lever is either massive executed or bent from a sheet accordingly.
  • the guide part 7 is curved over its length executed, as shown in Fig. 2, wherein the center of the curvature approximately above the offset path 15 of the pedal plate 9 lies, taking into account is that the push rod 3 is substantially horizontal runs so that the offset path 15 parallel to Push rod 3 is.
  • points the rail 4 for guiding the guide part 7 is a corresponding one Curvature, especially the lower one Area of the bottom 6 forms a support 11.
  • In the Rail is approximately at the level of the pedal shaft 1 Counterpart 12 for receiving those exerted on the pedal Operating forces.
  • FIG. 2 shows two extreme positions of the pedal setting. Because of the chosen Center of curvature for the guide member 7 results between the extreme positions a roughly horizontal Offset path 15 of the pedal plate 9.
  • the adjustment can be done by an electric motor.
  • a pinion 13 can be rotated below the pedal shaft 1 arranged on the rail 4. This pinion 13 meshes with a toothing 14 of the guide part 7.
  • An electric motor to operate the pinion 13, which is not with the push rod lever 2 must be connected, so when you press of the pedal does not need to be swiveled over, can a flexible shaft can be connected to the pinion 13. The The electric motor can then be firmly connected to the vehicle body.
  • a connection of the pinion 13 would also be conceivable with a gearbox that has a lateral offset of one Converting the piston into a rotary movement of the pinion.
  • Fig. 3 shows an exploded view a further embodiment of the invention.
  • the rail 4 is made two mirror images of each other Plates 20, 21, each with a curved Edge.
  • a guide 22, 23 is rectangular at each edge bent, which superimposed the leadership of the correspondingly curved guide part 7 of the pedal lever 10 form.
  • To get a low-friction sliding surface is on the inner surface of the inner flange a slider 24 made of Teflon.
  • a Abutment (corresponds to part 12, Fig. 2) is on the two
  • a shoulder is provided on each of the top sides of the plates 20, 21, the one extending approximately perpendicular to the upper edge Section of the paragraph is curved and is provided with a flange 25 or 26 as an abutment. This can also be provided with a sliding piece 27 made of Teflon become.
  • the pinion 13 meshes in the toothing 14 on the Inner edge of the guide part 7. A rotation of the pinion 13 thus calls for a displacement of the pedal lever 10 in the channel formed by the guides. Because of the Curvature of the guide and pedal lever, the pedal plate moves 9 also on a slightly curved path.
  • the geometry is set so that the Pedal plate 9 offset approximately parallel to the push rod and while maintaining an approximately constant distance from Adheres to the vehicle floor.
  • the effective lever arm kept essentially constant, so that the gear ratio through a pedal adjustment is not significantly changed.
  • a Opening 32 serves to receive the fork pin.
