This track-guided vehicle is provided with a car body, and a bogie that supports the car body from the bottom, and has a frame capable of pivoting around an axis perpendicular to a track. The bogie is provided with: a car body tilting part that tilts the car body to the left and right in the direction of travel; a detection part that detects the amount of pivot of the frame; and a tilt control part that allows the car body to be tilted by the car body tilting part on the basis of the amount of pivot detected by the detection part.

An electric vehicle for routing inspection of power transmission lines, includes a body; a running mechanism mounted to the body, comprising a front wheel and a rear wheel connected by a cross beam and rolling on the cable; an obstacle sensor and a cam rotatably mounted to the cross beam, the cam rotating to roll onto the cable after an obstacle is detected on the cable such that the front wheel is raised to a position above the cable, and the cam continuing rolling on the cable after the front wheel passes the obstacle such that the front portion of the cross beam falls back downwards and the front wheel then falls back onto the cable, a hanging seat rotatably hanging to the body and a control device at least partially disposed in the hanging seat and comprising a braking device.

A bogie includes a bogie frame, a first running wheel and a second running wheel, at least one driving device, a first horizontal wheel, a second horizontal wheel, a first horizontal safety wheel connected to the first horizontal wheel and moving in synchronization with the first horizontal wheel, and a second horizontal safety wheel connected to the second horizontal wheel and moving in synchronization with the second horizontal wheel. The bogie frame has a straddle recess suitable for straddling a rail. The first running wheel and the second running wheel are pivotably mounted onto the bogie frame respectively and are coaxially spaced apart. The at least one driving device is mounted onto the bogie frame and located between the first running wheel and the second running wheel to drive the first running wheel and the second running wheel.

A preload and retraction device (10, 10) of a wheel assembly comprises a linear guide (11), an internal slider (12) and an external slider (13) movable along the linear guide (11), a linear elastic member (14) arranged to connect the two sliders (12) (13), a first wheel support arm (15) integral with the internal slider (12) and a second wheel support arm (19) integral with the external slider (13), with the external slider (13) carrying a weight support wheel (20) that is actuated and the internal slider (12) carrying a traction wheel (16) that comes into contact with a rolling surface with a preload force that is a function of the geometry of the system. The use of the device (10, 10) is particularly advantageous for supporting the wheels in a self-propelled cart (100) of the type suitable for moving along a railway track for the inspection of the underbody of railway vehicles as it greatly facilitates and at least partially automates the installation of the self-propelled cart (100) on the track.

A drone with railway driving capabilities has a drone body and at propeller arms. Each propeller arm has a propeller assembly having a propeller driven by a motor assembly. The propeller assembly of at least one propeller arm has a rotatably mounted propeller guard placed coaxially with the propeller. The propeller guard is shaped as a train wheel and is driven by the motor assembly. The propeller arm has an actuated joint for providing the propeller assembly with at least one rotation degree of freedom so that the propeller can be rotated between a flight mode and a driving mode and back. The flight mode involves a more horizontal orientation of the propeller assembly for providing an upwardly directed thrust force to the drone, in operational use, and the driving mode involves a more vertical orientation of the propeller assembly for allowing the respective propeller guard to drive on the railway track.

A system for zero radius direction changes in an independent cart system includes a drive magnet array movably mounted to a mover. The drive magnet array includes at least one drive magnet configured to engage an electromagnetic field generated by coils extending along a track and a first engagement member for selectively positioning the drive magnet array between at least a first position and a second position. A switch track segment defines at least a first and second path for the mover. The first path includes coils to generate the electromagnetic field along the first path, and the second path includes coils to generate the electromagnetic field to along the second path. The drive magnet array is aligned with the first path when the drive magnet array is in the first position and with the second path when the drive magnet array is in the second position.
