Railroad vehicle with energy regeneration

A railroad vehicle (1500) for carrying freight is described. The railroad vehicle (1500) comprises power regeneration capability through a traction motor (1530) linked to a driving wheel (1520D), an electrical energy storage system (1550), a controller (1570) that may selectively operate the traction motor (1530) in a motoring mode, a coasting mode, or a dynamic braking mode. In the dynamic braking mode electrical energy from the traction motor (1530) is transmitted to the electrical energy storage system (1550). The controller (1570) is in communication with a communication link (1580) that receives control commands from an external control source (1595), and those control commands indicate the operating mode for a particular period of time.

Railroad system comprising railroad vehicle with energy regeneration

A self-powered railroad system (1700), in one embodiment, comprises a locomotive (1710), a control source (1715), and a plurality of load units (1720A-K and 1730A-G), some of which are railroad vehicles (1720A-K) comprising the components of railroad vehicle (1500) that provide for selective operation in a motoring mode, a coasting mode, or a dynamic braking mode. The self-powered railroad system may also comprise a control source and at least one railroad vehicle controlled by the control source, such as for coupling, uncoupling, and moving to or from a loading dock.

Autonomous transport system

An autonomous transport system is disclosed, formed by four main subsystems: a channel subsystem; a vehicle subsystem; a wheel guide subsystem and central control station subsystem. The system is designed for the transportation of people or goods, to be used in tall buildings and in small and large scale urban environments. It comprises unitary vehicles that may move in different directions: horizontal, steeply sloped and also vertical tracks, thanks to novel traction wheel assemblies that roll on carefully designed wheel tracks. The system's cabin maintains the horizontal level / position regardless of the changes of track direction or slanting thanks to pendulum based automatic level control and may rotate up to 180° under normal conditions and even a full 360° turn respect to the wheel assembly in space restricted positions. The cabin is mounted on a cantilever, thereby displacing its center of gravity respect of the wheel guides. Thus, a lever action is established, which presses the wheels against the wheel tracks and therefore enough frictional resistance is obtained so as to avoid wheel slippage on the wheel tracks. The vehicles are moved by non-polluting, electric drives that move and stop them with high energy savings. The vehicle runways are designed taking in account safety features against fire hazards. Several vehicles may be used at the same time and on the same track and may run individually or in groups, conforming a train. The system allows for vehicles to be parked in bypassed positions or else they may be disengaged from the convoy to be used individually.
