Abstract

Dispositif destiné à améliorer la directin des engins chenillés lorsque celle-ci est assurée par une transmission hydrostatique superposant sa vitesse à celle de la sortie de la boîte de vitesses. Il comprend outre une pompe à débit variable, un moteur hydraulique à cylindrée réglable, la plus petite cylindrée correspondant aux virages les plus fréquents, les plus grandes étant appelées automatiquement quand c'est nécessaire, lors des virages en terrain de forte adhérence. variation de cylindrée entraîne corrélativement le changement de rapport de la boîte de vitesses de manière à conserver le rayon de virage sensiblement constant au cours de cette manoeuvre. L'invention peut être utilisée sur tous les véhicules chenillés.
