Definitions

  • the input gearbox section may be in the form of a multi-ratio powershift gearbox with one or more clutches which when disconnected disconnect drive through the input gearbox.
  • An example of such an arrangement is shown in the Applicant's co-pending UK patent application no. GB0709636.5.
  • the present invention is also applicable to a multi-ratio powershift transmission of the form shown in Figure 2.

Abstract

La présente invention concerne un agencement de transmission de véhicule comprenant une boîte de vitesses (10) à rapports multiples. La boîte de vitesses entraîne une ou plusieurs roues du véhicule à partir d’un moteur associé (12) via un moyen de déconnexion d’entraînement. Un système de commande (110) est agencé de façon à garantir que lorsque le véhicule est immobilisé (a) le moyen de déconnexion d’entraînement se place dans un état dans lequel aucune puissance n’est transmise du moteur à la boîte de vitesses et (b) plus d’un rapport de vitesse est engagé dans la boîte de vitesses pour verrouiller la boîte de vitesses et donc empêcher la ou les roues de tourner, immobilisant ainsi le véhicule.
