Abstract:
1. A device for suspending a first element on a second element of a rail vehicle, the device comprising: two longitudinal connection rods, each connected to the first element at a first connection location, and connected to the second element at a second connection location, the two connection rods being longitudinally offset relative to each other; and at least one resilient member interposed between the two connection rods defining at least a vertical stiffness of the suspension device, the at least one resilient member being a sandwich including a plurality of layers of a resilient material and a plurality of metal plates interposed between the layers of resilient material and adhesively-bonded to the resilient layers, the at least one resilient member having a compression axis forming an angle with respect to an axis that extends through the first connection locations of the two connection rods such that forces acting upon the resilient member when the second element is subject to a vertical force are both a compression force and a shearing force.
