Title (EN) SAFETY DEVICE FOR TRACTOR AND TRAILER
(FR) DISPOSITIF DE SECURITE POUR TRACTEUR ET SEMI-REMORQUE
Abstract: front page image
(EN)The object of the invention is to eliminate the problem arising in road accidents of a tractor and its trailer, where often the tractor folds back violently against its trailer, which is often killing for the driver. Further, at each start, the driver is shaken vertically producing a settling down of the vertebra. The invention comprises an attaching saddle (1) fixed to the frame (2) as close as possible to the front axle. The front load of the trailer is supported by a jack (5) of which the roller (7) rotates on a curved rail (9) according to a radius starting from the center of the saddle. The liquid pressure of the jack is adjustable so that the saddle supports part of the front load of the trailer in order to eliminate the starting jolts.
(FR)L"invention consiste a supprimer le fait qu"actuellement, dans les accidents routiers de tracteur et sa semi-remorque, il arrive souvent que le tracteur se "mette en portefeuille" brutalement contre sa semi-remorque, ce qui est souvent mortel pour le chauffeur. De plus, a chaque depart, le conducteur est secoue verticalement, ce qui lui provoque un tassement de vertebres. L"invention comprend une sellette d"attache (1) fixee sur chassis (2) au plus pres de l"essieu avant. La charge avant de la semi-remorque est supportee par un verin (5) dont le galet (7) tourne sur un rail (9) courbe suivant un rayon partant du centre de la sellette. La pression du liquide du verin est reglable pour faire supporter par la sellette une partie de la charge avant de la semi-remorque, afin d"annuler les secousses de depart.
