More Information
Summary:A transmission with a number of fixed gear ratios has an automatic selector system which has a single actuator (6) to select the gate and the gear. The actuator is moved axially and rotationally to move through the gate and to select the particular gear ratios. An intermediate element with a return spring provides a simple return movement. The actuator operates on a central control shaft and the system includes a solenoid to hold particular settings, or an electric servo motor to hold the settings. Un dispositif de commande sert au dégagement/ engagement et à la sélection automatisés d'un rapport d'une boîte de vitesses - d'automobile notamment - avec un élément de commande à actionneur.L'actionneur comporte un entraînement dont la sortie confère à l'élément de commande un mouvement pour le dégagement/ engagement d'un rapport ou la sélection d'une rainure d'enclenchement de rapports, et agit simultanément sur un accumulateur de force commandant un élément intermédiaire en vue d'un dégagement/ engagement de rapport ou de la sélection d'une rainure d'enclenchement, la commande de l'élément intermédiaire étant limitée à une position prédéterminée par au moins un élément de retenue.Applicable en particulier à une boîte de vitesses conçue au départ pour une commande manuelle.
