Definitions

  • the invention relates to an accelerator pedal for controlling an engine of a motor vehicle according to the preamble of claim 1.
  • Such accelerator pedals are used in motor vehicles to transmit control commands generated by a driver by operating the accelerator pedal to a corresponding vehicle control.
  • the position of the accelerator pedal is determined by a sensor and transmitted to the vehicle control.
  • a pedal in which a special friction element is arranged, which cooperates with a friction surface, which is fastened to a second end region of the pedal.
  • a variable frictional force is to be applied, which is intended to dampen a force applied to one end of the pedal force.
  • the pedal is complex to produce.
  • DE 102 58 285 A1 discloses an accelerator pedal module in which a pedal lever is rotatably supported in a bearing block.
  • the bearing block has a bearing area with a bearing bore, in which at least part of a sensor shaft is rotatably mounted. At least part of a radially outer circumferential surface of the bearing area forms a bearing surface for the pedal lever.
  • a rigid pivot bearing of the pedal lever is to be achieved, whereby angular errors of the sensor shaft to be avoided. Construction and production of the accelerator pedal module are relatively complex.
  • DE 10 2005 013 442 A1 describes an accelerator pedal module in which a sensor comprises two bipolar magnets with a sensor element arranged between them. A change in the direction of the magnetic field due to a pivotal movement of a pedal is converted by the sensor into an electrical signal representing a position of the pedal.
  • This accelerator pedal module is relatively expensive.
  • the object is solved by the features of claim 1.
  • the housing is formed in two parts from a shell and a lid, wherein the lid is designed as a bearing block for the pedal lever and fastened to the shell.
  • the accelerator pedal is composed of only a few components.
  • the parts of the accelerator pedal can be largely simply shaped, which reduces the manufacturing costs.
  • the assembly takes place by simple mating and partly by additional fastening.
  • Bearing shells according to claim 2 can be made of a special friction material and thus ensure a desired force hysteresis of the accelerator pedal. They can be manufactured with optimum material use and e.g. be mounted by pressing on appropriately trained points in the storage area of the accelerator pedal.
  • Coil springs are available with defined spring force. If two coil springs of different diameters are used, the one with the smaller diameter can be arranged in the other, which minimizes the space requirement.
  • the cover is pivotally mounted about an axis parallel to the axis of rotation of the pedal lever in the shell, wherein the coil springs are positioned from the axis of rotation about the axis spaced.
  • the force-hysteresis properties of the accelerator pedal can be set; These are preserved as far as possible over the service life because any slight wear that occurs is compensated by the pivoting as a result of the spring force.
  • a virtually backlash-free storage of the pedal lever is achieved, which increases the measurement accuracy of the sensor.
  • the arrangement of the sensor centrally in a recess of the pedal lever also minimizes the space requirement, thus allowing a very compact design of the accelerator pedal.
  • An arrangement of a stator of the sensor together with electronics in a sensor housing protects the sensitive parts from dirt and moisture in a relatively simple manner and is easy to assemble.
  • the integrated socket on the sensor housing can be realized with relatively little additional effort and simplifies the installation of the accelerator pedal in the motor vehicle.
  • a locking assembly of lid and shell is safe and relatively easy.
