Definitions

  • the invention relates to a device for limiting the maximum speed of a vehicle driving internal combustion engine according to the preamble of the main claim.
  • the invention is therefore based on the object to provide a device of the type described in the preamble of the main claim, with which the noise level of the internal combustion engine can be kept to a minimum and which, if necessary enables operation of the internal combustion engine at any desired operating point.
  • the object is achieved by the characterizing feature of the main claim.
  • each operating point of the internal combustion engine can be reached by means of a corresponding fuel metering via the actuator which defines this (e.g. accelerator pedal or adjusting lever on the injection pump), so that the operating state of the internal combustion engine can be optimally adapted to the respective driving conditions at any time .
  • the actuator which defines this (e.g. accelerator pedal or adjusting lever on the injection pump), so that the operating state of the internal combustion engine can be optimally adapted to the respective driving conditions at any time .
  • the adjusting lever 1 is the adjusting lever arranged on an injection pump of an internal combustion engine driving a vehicle, the deflection of which represents a measure of the amount of fuel to be injected.
  • This adjustment lever 1 is via a transmission linkage shown only schematically in the drawing 3 connected to an accelerator pedal 2 to be actuated by a driver.
  • the adjusting lever 1 is rotatably supported on a shaft 4.
  • the piston rod 5 of a piston 7 guided in a cylinder 6 serves as a stop for the adjusting lever 1 and is supported against the cylinder 6 in the manner shown via a compression spring 8.
  • a movement of the accelerator pedal 2 in the direction of arrow 9 or the adjusting lever 1 in the direction of arrow 10 causes an increase in the fuel injection quantity.
  • the piston 7 and the cylinder 6 enclose a working space 11 which can be pressurized by a hydraulic fluid via a pressure medium line 12 by means of a pump 13. Instead of hydraulic action, a pneumatic action on the piston 7, for. B. possible by means of an air pressure accumulator.
  • a pneumatic action on the piston 7, for. B. possible by means of an air pressure accumulator.
  • Arranged in the pressure medium line 12 is an electromagnetically acting 3/2-way valve 14, which in turn is controlled via a circuit 15 in which two switches 16 and 17 and a DC voltage source are integrated.
  • the switch 16 is transferred to the closed position when the internal combustion engine is started when the ignition is switched on.
  • the switch 17 can be actuated via a relay 19 in such a way that it is closed when the relay 19 is in the activated state.
  • the working space 11 is connected directly to a reservoir 21 via a return line 20, so that the compression spring 8 can hold the piston 7 unhindered in the position in which the as a stop for the adjusting lever 1 acting piston rod 5 allows a maximum deflection of the adjusting lever 1, that is, an operation without limitation of the maximum speed.
  • the switch 16 is therefore always closed during operation of the internal combustion engine.
  • An additional closing of the switch 17 or activation of the relay 19 required to limit the maximum rotational speed takes place according to the invention when the vehicle is at a standstill, the signal SI characterizing the vehicle standstill being derived from the tachometer of the vehicle and, after appropriate preparation, the relay 19 activated.
  • the parameters described below which also indicate a standstill of the vehicle, can be used as signals for activating the relay 19 (SIV and SV).
  • Drive torque (SIV) parameter In the event of a vehicle standstill, no more torque is transmitted to the drive wheels of the vehicle.
  • the relay 19 can thus also be activated via a corresponding signal which is generated, for example, by means of a torque measuring hub arranged in the drive train between the transmission and the drive wheel.

Claims (3)

  1. Dispositif de limitation de la vitesse maximale de rotation du moteur à combustion interne d'un véhicule, dans lequel l'inflexion maximale d'un organe réglant, dont l'inflexion instantanée détermine le débit de carburant devant être injecté dans la chambre de combustion du moteur, peut être réduite si nécessaire, caractérisé en ce qu'un signal caractérisant l'immobilisation du véhicule active la limitation de vitesse, ce signal étant généré par le tachymètre ou le frein de blocage ou un détecteur de couple monté entre la boîte à vitesses et la roue de commande.
  2. Dispositif selon la revendication 1, caractérisé en ce que le signal caractérisant l'immobilisation du véhicule actionne un distributeur (14) monté sur une canalisation de fluide sous pression (12) de manière qu'un élément de piston (7) prévu comme butée pour l'organe réglant (1) et mobile dans un cylindre (6) raccordé à la canalisation (12 ) de fluide sous pression soit maintenu à la position limitant l'inflexion maximale de l'organe réglant en cas d'immobilisation du véhicule.
  3. Dispositif selon la revendication 2, caractérisé en ce que le distributeur est un distributeur 3/2 agissant par voie électromagnétique et monté dans un circuit (15) qui peut être coupé par au moins un interrupteur(17) reconnaissant l'immobilisation du véhicule.
