Title (EN) CONTROL MECHANISM WITH A RACK
(FR) MECANISME DE COMMANDE A CREMAILLERE
Abstract: front page image
(EN)The control mechanism with a rack comprises a rack (1) and a control piston (3) located in a cylinder-shaped housing (4). The rack and the piston are axially movable with respect to each other along a limited path. For that purpose a control valve (14) is provided on the control piston. A sprocket wheel (6) is movably mounted in the housing. Contrary to presently known control rack devices the housing is movably mounted in the vehicle. A crank-arm (2) connected to the control piston is fixedly mounted in the vehicle. At least one steering rod is provided in the housing: it transmits the reciprocating movement of the steering mechanism, and is adapted to the steering wheels of the vehicle. The pressure-transmitting conduits which feed the valve are, preferably, located in the crank-arm in the form of channels. The control device is characterized by its small size.
(FR)Le mecanisme de commande a cremaillere comporte dans un boitier (4) en forme de cylindre, une cremaillere (1) et un piston de commande (3). La cremaillere et le piston sont mobiles axialement l"un par rapport a l"autre le long d"un chemin delimite. Pour ce faire, une soupape de commande (14) disposee sur le piston de commande est en action. Un pignon dente (6) est dispose de maniere mobile dans le boitier. Au contraire des commandes a cremaillere connues actuellement, le boitier est dispose de maniere mobile dans le vehicule. Une bielle de piston (2) liee au piston de commande est disposee de maniere fixe dans le vehicule. Une barre de direction au moins se trouve dans le boitier: elle transmet le mouvement de va-et-vient du mecanisme de direction, et est adaptee aux roues directrices du vehicule. Les conduites pour la transmission de la pression qui alimentent la soupape sont, de preference, disposees, sous forme de canaux, dans la bielle du piston. Le dispositif de direction se distingue par ses petites dimensions.
