Abstract
An articulated coupling for two rail vehicles supported by a common bogie comprises: (A) a toroidal part (1) connected to one of the vehicles, said part being frustoconical in its bottom zone and cylindrical in its top zone, and having a cylindrical ball in its center and a shoulder around the top thereof; and (B) a support part connected to the other vehicle, enveloping the toroidal part, and comprising a sole plate (9), a toroidal articulated coupling element made of resilient composite material, a cylindrical peg (17) fixed to the sole plate, engaged in the ball of the toroidal part, and terminated by a horizontal shoulder; and an internal cylindrical part (20) facing the cylindrical external surface (3) of the toroidal part.
Claims7
An articulated coupling for two rail vehicles supported by a common bogie between the two vehicles via resilient elements, wherein the coupling comprises:
- (A) a toroidal part connected to one of the vehicles, having a frustoconical surface in its bottom zone and being cylindrical in its top zone, said toroidal part including a cylindrical ball through its center and being provided with a horizontal circular shoulder around the top of its cylindrical ball;
- and
- (B) a support part connected to the other vehicle, enveloping the toroidal part and comprising:
- (a) a sole plate at a lower level than the toroidal part;
- (b) a toroidal articulated coupling element of resilient composite material built up from metal plates sandwiched between layers of resilient material resting on the sole plate and surrounding and in contact with the frustoconical outer surface of the toroidal part;
- (c) a cylindrical peg fixed to the sole plate, engaged in the cylindrical ball of the toroidal part, being of smaller diameter than said ball and being terminated by a horizontal circular shoulder facing the horizontal circular shoulder of the toroidal part;
- and
- (d) in the top portion of its peripheral zone, an internal cylindrical part facing the cylindrical outside surface of the top zone of the toroidal part.
