Coupling, useful for vehicle, comprises first and second metal elements having first and second contact surfaces, where second element comprises flange extending perpendicular to first contact surface and collar contacted with flange

摘要

The coupling comprises a first metal tubular element having a first contact surface (110a), and a second metal element (120) that is fixed on the first metal element (110) by the first contact surface and comprises a tubular flange (120b) extending perpendicular to the first contact surface, a collar directly contacted with the flange and a second contact surface. The second contact surface is in contact with the first contact surface. A filler metal (130) is disposed in a groove extending between the first metal element and the collar, and connects the metal elements by soldering. The coupling comprises a first metal tubular element having a first contact surface (110a), and a second metal element (120) that is fixed on the first metal element (110) by the first contact surface and comprises a tubular flange (120b) extending perpendicular to the first contact surface, a collar directly contacted with the flange and a second contact surface. The second contact surface is in contact with the first contact surface. A filler metal (130) is disposed in a groove extending between the first metal element and the collar, and connects the first and second metal elements by soldering. The collar and the flange form a monoblock plate having a constant thickness. The first metal tubular element extends according to a direction, which is perpendicular to the flange. The collar forms an angular sector (= 180[deg] ). The first metal element is a crosshead fixed to a frame of a vehicle by horizontally extending pillars. The second metal element forms a supporting leg resting on the frame of the vehicle, and is a support and a grip fixed to the frame of the vehicle by the pillars. The second metal element comprises a first flange, a second flange, a base connecting the first and second flanges, a first collar directly connected with the first flange, and a second collar directly connected with the second flange. The first and second flanges extend perpendicular to the first contact surface so that the second element has a U-shape. A first cord of the filler metal is disposed in a first groove provided between the first metal element and the first collar, and joins the first metal element and the first collar. A second cord of the filler metal is disposed in a second groove provided between the first element and the second collar, and joins the first metal element and the second collar. The collar has an annular shape, and completely surrounds the first metal element.
