Double-axle drive for railway trucks of railraod vehicles

A double-axle drive for rail vehicles, comprising:

• rotatably supported first and second lontigudinally spaced tranversely wheeled axles;
• a rotatably supported hollow shaft surrounding each axle;
• a drive motor located between said axles having a drive shaft at respective ends;
• gear means between each of said drive shafts and said hollow shafts at the respective ends of said motor to rotate said hollow shafts upon rotation of said drive shafts;
• elastic coupling means connected adjacent each end of said hollow shaft to each first and second axle to rotate each of said axles, elastic coupling means comprising plural circumferentially spaced pin means secured to one of said hollow shaft and said axle with the axes thereof projecting radially, means defining plural circumferentially spaced arms secured to the other of said hollow shaft and said axle, said arms extending radially and being oriented in the circumferential spacing between said pin means, each said pin means and said arm having oppositely facing, circumferentially facing surfaces thereon, opposing circumferentially facing surfaces on mutually adjacent arms being located on opposite sides of a pin means located therebetween, the size of said pin means being smaller than the size of the circumferential distance between said opposing circumferentially facing surfaces to define a space therebetween, and elastically yieldable elements received in said space between said pin means and said opposing circumferentially facing surfaces, said elastically yieldable elements being fixedly secured between said pin means and each of said opposing circumferentially facing surfaces, the planes of said oppositely circumferentially facing surfaces on said pin means and said opposing circumferentially facing surfaces on mutually adjacent arms being angularly related at an acute angle to the axis of an associated one of said axles, and further being inclined at an acute angle to each other, and the planes of the oppositely facing surfaces on said elastically yieldably element also being inclined at an acute angle to each other so as to facilitate easy reception between mutually adjacent and opposing circumferentially facing surfaces on said pin means and said arm, said opposing circumferentially facing surfaces each having a V-shaped concave contour, said opposite sides of said pin means having a V-shaped convex contour, and said elastically yieldable elements being blocks arranged in opposing pairs and having two legs arranged in a V-shape, the inner surfaces of said two legs engaging said V-shaped surfaces of said pin means and the outer surfaces of said two legs engaging said V-shaped surfaces of said concave contours on said arms.
