Abstract
The invention relates to a bogie for vehicles of the type which has at least two movable axles against which the chassis of the vehicle rests over an equalizing beam arranged on either side of the chassis, the vertical forces being transmitted between the wheel axles and the equalizing beams by transmitting devices which are rigid when biased by tension and pressure stresses but yieldable to bending and shearing stresses. The connection points for these transmitting devices, at least at one axle, are located at a distance from the axle on a member which is rigidly connected to the axle, and a spring is arranged at such member to compensate for the moment conditioned by the distance between the axle and the connection points and resulting from movement of the axle.
