Resilient railway truck double axle drive

摘要

A double axle drive for railway trucks of rail vehicles. The axis of rotation of the drive motor extends parallel to the longitudinal axis of the vehicle and extends between the wheel-set axles. The drive motor drives the wheel sets through a bevel gear arrangement. Each bevel gear arrangement has, on the driven side thereof, a hollow shaft which encircles the respective wheel-set axle. The hollow shaft is connected at its two ends through an elastic coupling to the wheel-set axles. The entire drive system is supported on the two axles through four couplings. Each of the four couplings is composed of rotation-symmetrical members, one being connected to the hollow shaft and the other to the axle, and an interconnecting flexible joint sleeve circumferentially spaced around the periphery of the two coupling halves.
