A chassis for a rail vehicle, in particular with inboard wheel sets, with at least one transmission, at least one transversely mounted drive motor and at least one chassis frame, wherein the chassis frame includes at least one crossmember and at least a first longitudinal carrier and a second longitudinal carrier, where at least a first elastic bearing, a second elastic bearing and a third elastic bearing are arranged between the drive motor and the chassis frame, and where in each case one of the elastic bearings is arranged on at least one of the longitudinal carriers in order to provide advantageous construction conditions.

A railroad switch (in USA), turnout, or [set of] points (Europe) is a mechanical installation enabling railway trains to be guided from one track to another, such as at a railway junction or where a spur or siding branches off. This invention describes a rail transportation system that allows vehicles to change tracks at railroad switch locations while all supporting and guiding rails remain static. Vehicles have diverters that apply lateral force to direct the vehicle to go onto the desired track, right, left, or straight ahead. This is enabled by the diverters plus rail wheels that have inside flanges and wide cylindrical surfaces. This innovation allows rail vehicles to travel through a connected rail system like a highway system that is transporting trucks, buses, and cars on paved roads. This system may operate under a computerized traffic control system and allows mass transit systems to respond to ride requests, enabling 24-hour route-adaptive mass transit. The track system can be placed into a road, like tram (or street cars) tracks. Vehicle can form into coupled trains while moving, and passengers can change routes in transit by changing coupled cars. Rail switches can be static for self-switching vehicles, but normally static components can adapt to accommodate conventional rail-switched rail vehicles.

The present disclosure discloses a rail vehicle. The rail vehicle includes: a plurality of bogies, where the bogie has a straddle recess suitable for straddling a rail; and a vehicle body, where the vehicle body is connected to the plurality of bogies and pulled by the plurality of bogies to travel along the rail, and the vehicle body includes a plurality of compartments hinged sequentially along a length direction of the rail; the plurality of compartments forms at least one compartment group, the compartment group includes three compartments hinged sequentially, and the bottom of each of only compartments that are located at two ends of the compartment group and that are of the three compartments is connected to the bogie; and in the length direction of the rail, a surface that is of a compartment at at least one end of the vehicle body and that faces away from an adjacent compartment is provided with an escape door that can be opened and closed. The rail vehicle according to this embodiment of the present disclosure facilitates optimization of the structure of an escape passage, reduction in occupied space and the weight borne by the rail, and improvement in stability, and is flexible in steering and low in costs.

A drive system includes a motor having a rotatable output shaft that is operably coupled to a lead screw by a transmission that converts rotary output of the motor into linear translation of the lead screw. The drive system further includes a position sensor configured to sense a position of the lead screw. A method for determining a backlash of the drive system includes the steps of sensing an initial position and driving the lead screw in a first direction to a calculated second position by controlling the motor to rotate the output shaft an amount that corresponds to a distance between the initial position and the calculated second position. The method further includes the steps of sensing an actual second position of the lead screw; and determining a backlash value according to a difference between the calculated second position and the actual second position.

An overhead transport vehicle includes: a traveling portion including traveling wheels to travel on a traveling rail, and a main body supported by the traveling portion via a suspension and configured to hold an object to be transported. The overhead transport vehicle includes a contact roller to contact with a curved outside portion of the traveling rail in a curved section from below on an upper surface of the main body facing the traveling rail in a vertical direction.
