Definitions

  • the invention relates to a throttle valve assembly with accelerator pedal and electric motor drive according to the preamble of claim 1.
  • Such throttle valve neck are known and often have a plurality of return springs which are intended to bring the throttle valve into an emergency running position via the aid lever (DE-A1 41 41 104).
  • the return springs must be carefully coordinated.
  • the sum of the forces of the first and second return springs acting in the closing direction must not be greater than the force of the third return spring acting in the opening direction.
  • the electromotive actuator must be designed so strong for the idle control range that it can adjust the throttle valve in the opening direction against the first and second return spring and in the closing direction against the third return spring.
  • the object of the invention is to develop the device mentioned at the outset in such a way that only a return spring is required and auxiliary levers and the like are omitted, that is to say the mechanics are simplified.
  • Fig. 1 shows a throttle valve assembly 1 with a throttle valve shaft 2, on which a throttle valve 3 and a disc 4 are attached.
  • a motor lever 6 with a bushing 7 is pushed on and secured by a throttle lever 8 connected to the shaft 2.
  • An electric motor engages on the motor lever 6 via a transmission, the electric motor being controlled in a known manner by an electronic control unit.
  • the throttle lever 8 is held by a spring 9 clamped between the throttle lever 8 and the engine lever 6 against an engine lever stop 10 (FIG. 2) and when the accelerator pedal is actuated beyond an opening amount of the throttle valve 2 set by the engine lever 6, it also lifts off the latter.
  • a sleeve 11 connected to the engine lever bushing 7 has a slot 12 into which one end 13 of the spring 9 clamped between the engine and throttle lever is inserted, and receives a clamp spring 14, which has both ends 15, 16 of an engine lever pin 17 and a housing pin 18 clutched together, as shown in Fig. 2 as a detail from Fig. 1.
  • Fig. 3 shows an alternative to the detail from Fig. 2, in which the clamp spring 14 is mounted in or on a bushing 19 which, as an intermediate member, has a stop 20 for one of the spring legs 15, 16 and a stop 21 for the motor lever pin 17 and one Has stop 22 for the housing pin 18.
  • the other spring leg rests on the housing pin 18 '.
  • This version is suitable for pure e-gas operation, in which there is no need to operate the accelerator pedal via a Bowden cable.
  • the mode of operation of this design is the same as the embodiment according to FIG. 2, but has the advantage of easier assembly compared to the embodiment according to FIG. 2.
  • the positions of the motor lever pin (17) and the spring leg / stop 21 shown in broken lines shows the mode of operation.
  • An accelerator pedal lever travels with a stop in the movement path of the throttle lever 8 with the accelerator pedal drive and forcibly takes it with it, so that the throttle valve 2 is opened. If the engine lever 6 does not follow this throttle valve opening sufficiently quickly, the throttle lever 8 lifts off the engine lever stop 10 with tensioning of the spring 9.
  • the accelerator pedal lever can additionally have a driver stop, which causes the throttle valve 2 to be forced to close when the accelerator pedal is reset. However, this limits a cruise control function.
  • the motor lever 6 assumes a position which is fixed by the motor lever and the housing pins 17, 18. This position of the engine lever 6 causes an emergency opening of the throttle valve 2.
  • the electric motor drive strives to perform speed control of the internal combustion engine, that is, the engine lever 6 is for this purpose from the position fixed by the housing pin 18 into a smaller opening of the throttle valve Position moved, in which case the spring clip 14 is tensioned.
  • the motor lever 6 is adjusted the other way round in the sense of a throttle valve opening, the clamp spring 14 also being tensioned here.
  • the electric motor is designed for a safe adjustment of the motor lever 6, the clamp spring 14 having the same clamp torque in both adjustment directions, which is advantageous for a low drive power of the electric motor, that is, it is only designed for this low power and requires only a small one Installation space.
