CA 2178614

The support of a wagon body on a chassis is disclosed, in particular the bogie of a rail vehicle. A known support has a supporting element arranged between thechassis and the wagon body; the supporting element is supported by a roller bearing joint on the chassis and supports the wagon body on an upper joint. According tothe invention, a flange is arranged between the supporting element and the chassis, a first joint is arranged between the chassis and the flange and a second pint is arranged between the flange and the supporting element, in order to reduce surface pressure. At least one of these joints is a roller bearing joint with two rolling surfaces, of which one rolls on the flange and the other rolls on the chassis or supporting element. At least one of both mutually touching rolling surfaces is shaped as a cylinder and the bearing surface between both rolling surfaces is linear. The rolling movement of both rolling surfaces of one joint allows the supporting element to swivel in a plane and the other joint allows the supporting element to move perpendicularly to said plane.

L'invention concerne l'appui d'une caisse de wagon sur un châssis, notamment le bogie d'un véhicule sur rails. Un appui connu comprend un élément d'appui situé entre le châssis et la caisse de wagon soutenu sur le châssis par un joint à roulement et qui soutient la caisse de wagon sur un joint supérieur. Afin de réduire la pression superficielle, l'invention propose de monter un flasque entre l'élément d'appui et le châssis, un premier joint entre le châssis et le flasque et un deuxième joint entre le flasque et l'élément d'appui. Au moins un de ces joints forme un joint à roulement pourvu de deux surfaces de roulement, dont une roule sur le flasque et l'autre sur le châssis ou l'élément d'appui. Au moins une des deux surfaces de roulement en contact est cylindrique et leur surface d'appui mutuel est linéaire. Le roulement des deux surfaces de roulement d'un des joints permet à l'élément d'appui de pivoter dans un plan et l'autre joint permet à l'élément d'appui de se déplacer perpendiculairement à ce plan.
