Abstract

L'invention a trait à une transmission hydrostatique à embrayage et débrayage de roues motrices supplémentaires. Dans ladite transmission, le processus d'embrayage de roues motrices supplémentaires est déclenché par un distributeur 26 de façon que des canalisations principales 7 et 8 partant de la pompe de commande 1 soient reliées par un distributeur 29 aux moteurs hydrostatiques embrayables 20, 21 et simultanément des accouplements 22, 23 entre lesdits moteurs et les roues supplémentaires 30, 31 sont embrayés, tandis qu'à l'état débrayé, les moteurs hydrostatiques 20, 21 sont séparés des roues 30, 31. Application notamment aux engins de travaux publics.
