An autonomous vehicle for passengers includes four steerable wheels where each steerable wheel is steered by a steering system having a set of two actuators. One actuator of each set of actuators is powered by a first power source while the other actuator of the set of powered by a second power source. Four controllers each control one actuator of each set of actuators and one actuator from another set of actuators.

Steering system for an automated vehicle

A secondary suspension system for a railcar comprises a chassis, a primary spring, a levelling actuator, a first hydraulic circuit and a secondary spring. The levelling actuator is adapted to be connected to the carbody. A piston shoulder, located at the lower portion of the piston and below an opening in the chassis, reaches farther than the opening so as to be capable of catching the chassis. The secondary spring is at least partially positioned underneath the piston shoulder. The piston is operative to adopt a high position inside the body under a pressure of a hydraulic fluid injected in a lower chamber below a piston head. This makes the piston shoulder abut against the chassis, thereby compressing the primary spring between the body and the chassis without compressing the secondary suspension.

Height adjustable secondary suspension for a rail vehicle

A height compensation device for a railway truck having at least two pairs of rail engaging support wheels. The height compensation device is secured at opposed ends of a truck bolster and compensates for car body height loss after the wheels are re-profiled. The compensation device comprises a bearing element having a top support surface on which the car body rests. A displaceable height adjustment plate having one or more shim sections of different thicknesses is provided with one of the sections being disposed between the bearing element and the truck bolster by lifting the car body off the bearing element whereby to dispose the top support surface of the bearing element at a predetermined desired height above the truck bolster to maintain the car body at a substantially constant height from track level after wheel profiling.
