Abstract

L'invention se rapporte à un verrouillage de marche arrière à blocage automatique, avec une partie fixe dans laquelle se trouve un anneau de levage, des lamelles et un disque à rochet et cela pour une machine motrice avec boîte à vitesses. Ce verrouillage de marche arrière est prévu en particulier pour empêcher un véhicule de reculer sur un sol en pente et rendre superflu le maniement du frein à main lors d'une remise en marche dans le terrain. Ainsi, le démarrage est rendu plus facile, par exemple et en particulier pour des véhicules militaires et d'invalides. Les pièces des différentes formes d'exécution du verrouillage automatique de marche arrière, pour véhicules en particulier, présentées dans les figures, sont désignées par les chiffres ci-après : 1. Partie fixe; la Place réservée au palier de l'arbre de sortie; 2. Lamelles de verrouillage (lamelles); 2a Saillies des lamelles 2; 3. Goujon; 4. Ressorts de pression; 5. Disque à rochet - immobile pendant la marche avant; 5a Dents - échancrures - du disque à rochet; 6. Roue libre à rouleaux de blocageThe invention relates to a reverse gear locking with automatic locking, with a fixed part in which there is a lifting ring, lamellae and a ratchet disc and that for a prime mover with a gearbox. This reverse gear lock is designed in particular to prevent a vehicle from rolling back on sloping ground and to make it unnecessary to operate the handbrake when restarting in the field. Thus, starting is made easier, for example and in particular for military vehicles and invalids. The parts of the different embodiments of the automatic reverse gear locking, for vehicles in particular, shown in the figures, are designated by the numbers below: 1. Fixed part; the place reserved for the bearing of the output shaft; 2. Locking slats (slats); 2a Protruding slats 2; 3. Stud; 4. Pressure springs; 5. Ratchet disc - stationary during forward travel; 5a Teeth - notches - of the ratchet disc; 6. Freewheel with locking rollers
