Definitions

  • the invention relates to a method for controlling an automated gearbox according to the preamble of patent claim 1.
  • Such transmissions use at least partially the reservoir pressure of a vehicle in which they are installed.
  • the switching elements i. the Hauptabschaltventile and these downstream switching valves are supplied either directly with this supply pressure or system pressure of the vehicle or with a lowered for example by means of pressure reducing valves or the like constant operating pressure. This means that the load of the switching elements, the switching times, the switching noise, etc. can not or only to a small extent can be influenced.
  • the invention has the object to provide a method for controlling an automated transmission, which allows simple means a further optimization in the above sense.
  • the invention is based on the finding that the pressure chambers of all the Hauptabschaltventilen downstream actuating cylinder via associated switching valves or ventilation valves on the one hand and with each interconnected Druckzufilm decisen and on these switching valves or vent valves on the other hand connected to a Druckabfat protest so that about each actuating cylinder a Pressure reduction of the pressure supply lines is possible.
  • the invention is based on a method for controlling an automated manual transmission, with a plurality of associated switching valves or air valves pressure-actuated actuating cylinders, one or more the switching valves and ventilation valves upstream main shut-off valves, and with a control device for controlling these valves , whereby the respective Main shut-off valves downstream pressure lines communicate with each other.
  • Modern manual transmissions generally have at least one transmission brake, which is actuated by a unidirectional actuating cylinder, and whose pressure chamber is filled or vented via a first directional control valve and vented via a second directional control valve.
  • the first directional control valve and the second directional valve of the transmission brake are each switched to a Druckstoffbach bel permitting position, so that the pressure line system shorted to the Druckstoffabloomtechnisch and in this way is vented.
  • the prerequisite is, of course, that the gear brake is then currently not to be operated.
  • the switching system shown in the single figure for example, a pneumatic switching system for switching an automated gearbox for commercial vehicles, is powered by a vehicle-side pressure medium supply system, which has a pressure medium reservoir 2, with a pressure medium.
  • the switching system comprises by way of example a main shut-off valve 4 arranged downstream of the pressure-medium reservoir 2, which can connect or disconnect the circuit arrangement arranged downstream of this main shut-off valve 4 with the pressure medium reservoir 2.
  • a main shut-off valve 4 instead of the main shut-off valve 4, a plurality of parallel arranged Hauptabschaltventile may be provided.
  • the subordinate circuit arrangement comprises in the illustrated case two actuating cylinders 6 and 8, wherein the first actuating cylinder 6 is a double-acting actuating cylinder, for example, for selecting a gear or a shift gate, and the second actuating cylinder 8 is a single-acting actuating cylinder for a transmission brake.
  • the two pressure chambers 9 and 1 1 of the first actuating cylinder 6 are respectively filled by means of an associated 3/2-way valve 10 and 12 or vented via a Druckstoffabcontenttechnisch 14, while the single pressure chamber 13 of the second actuating cylinder 8 by means of a 2/2-way valve sixteenth filled and vented by means of a 2/2-Wege- valve 18 via the Druckstoffabcontenttechnisch 14.
  • the directional control valves 10 and 12 are also referred to as switching valves, the directional control valves 16 and 18 as ventilation valves.
  • the switching system here further comprises a third, single-acting actuating cylinder 20, which serves to actuate a transmission clutch.
  • the only pressure chamber 21 of the third actuating cylinder 20 is filled or vented via a 2/2-way valve 22 and vented via a 2/2-way valve 24 via the Druckstoffabstructuretechnisch 14.
  • the directional control valve 22 for filling the clutch actuating cylinder 20 is preceded by a check valve 26 to prevent venting of the clutch actuator cylinder 20 at a drop in the pressure supply.
  • the directional control valves 10, 12, 16, 18, 22, 24 associated with the positioning cylinders 6, 8, 20 and in particular the main shut-off valve 4 are controlled by a control unit, wel Ches for reasons of clarity is not shown, driven.
  • a pressure sensor 28 detects the target pressure in the main shutdown valve 4 downstream circuitry and supplies a corresponding signal to the controller.

Abstract

L'invention concerne un procédé de commande d'une boîte de vitesses automatisée comportant plusieurs vérins d'actionnement (6, 8, 20) actionnés par un agent sous pression par l'intermédiaire de soupapes de commande ou de soupapes d'aération et de purge (10, 12,16,18,22) correspondantes, une ou plusieurs soupapes de coupure principale (4) disposées en amont des soupapes de commande ou des soupapes d'aération et de purge, et un appareil de commande pour commander ces soupapes, les conduites de pression disposées en aval des soupapes de coupure principale (4) correspondantes étant reliées les unes aux autres. Les soupapes de coupure principale (4) étant, pour des raisons de simplicité de conception et de coûts, habituellement conçues comme de simples soupapes 2/2 voies qui permettent seulement d'augmenter mais pas d'abaisser la pression dans les conduites de pression situées en aval, il est prévu, pour abaisser la pression dans le circuit de conduites de pression (30,32,34) situées en aval des soupapes de coupure principale (4) correspondantes, de commander des soupapes de commande ou des soupapes d'aération et de purge (16,8) d'un vérin d'actionnement (8) momentanément non activé de telle façon que le circuit de conduites de pression soit en communication avec une conduite d'évacuation d'agent de pression (14).
