A segmented track for a Maglev vehicle includes a structural support portion and a Maglev portion fastened to the structural support portion. Each segment of the structural support portion is formed by fusing together three cast metal components. Neighboring ones of the structural support segments are joined together end-to-end by fused metal, and neighboring ones of the reaction rail segments are joined together end-to-end by fused metal. The positioning and joining of the successive segments is done in the field using on site jigs and machines.

The invention relates to the field of transport mechanical engineering and concerns friction shock absorbers for vehicles. The object of the invention is to improve the operational life, performance and reliability of a friction shock absorber. The friction shock absorber comprises housing (1) with bottom (2) and with orifice (3) formed by walls (4), internal surfaces (fv) whereof form alternating working beds (V1) and connecting beds (V2), and further comprises friction assembly (5) consisting of pressure wedge (6) and stay wedges (7) in contact with same, said stay wedges being provided with friction surfaces (fp), while return-and-retaining device (8) is located between bottom (2) and friction assembly (5). In addition, the area (S1) of contact between friction surfaces (fp) of stay wedges (7) and internal surfaces (fv) of walls (4) of orifice (3) in working beds (V1) exceeds the corresponding area (S2) of contact in the connecting beds (V2). The internal surfaces (fv) may be straight, while the values of angles (θ1) between adjacent internal surfaces (fv), which form working beds (V1), are lower than the values of angles (θ2) between adjacent internal surfaces (fv), which form the connecting beds (V2). The thickness of walls (4) of the orifice (3) is variable with an increase in the direction from the working bed (V1) to the connecting bed (V2). The contact between pressure wedge (6) and stay wedges (7) is provided along linked curved surfaces (fκ).

The present invention refers to an improvement developed on a pneumatic transport system for loads and/or passengers whose vehicles are not provided with on-board drive means, being guided on two exclusive tracks arranged in parallel, each track being dedicated to one travel direction, resulting in high transport capacity. The vehicles (1) travel over railway tracks (5) laid over an elevated track (6) supported by pillars (7). The center of the top of the superstructure of the elevated track (6) has a longitudinal slot (9) with seal (8) by means of which the mast (3) of the propulsion plate (4) is allowed to move freely along the path of the vehicle (1). The crossbeam is comprised by four beams which constitute the superstructure of the elevated track, being two turnout beams (6′) and two straight beams (6), whereby the four beams are permanently connected to each other and to the pillars (7) in the region of the heads to form a monolithic hyperstatic structure. In the superstructure of the turnout beams (6′) there are mounted the mobile rails (16, 18 and 21) with their respective drive mechanisms (17, 19 and 20) and locking (15). A section isolation valve is positioned inside the propulsion duct (12) of the turnout beams (6′) and is comprised of a shutter (40) and a linear actuator (41) which activates a set of two articulated rods (42) to the position of the limit stop (43).

A rail transport system having no internal drive is used for conveying bulk materials and includes an over-under bypass arrangement. The bypass arrangement includes drives, ramps and switches that allow trains to travel in both directions on two sets of tracks positioned above the same track footprint. Rail bypass arrangements for use with rail transport systems for conveying bulk materials and allowing bypass of a first train and a second train are also disclosed herein.

A submerged floating rail transit system comprises a first rope (102), a buoyancy tank (103), a rail (104), a gear (108), a driving mechanism, a cable (110) and a second rope (111); wherein one end of the first rope is anchored to the water ground (101), and the other end of the first rope is connected with the buoyancy tank; the rail is provided on the buoyancy tank, the gear is engaged with the toothed rail of the rail, and a driving mechanism is provided on the rail; the driving mechanism drives the gear to move along the extending direction of the rail; the driving mechanism comprises a shell (105), a first motor (106), a second motor (107) and a rotating shaft (109); one end of the second rope is connected with the shell, and the other end of the second rope is connected with a ship (113) on the water surface (112); the first motor and the second motor rotate in the same direction to drive the gear to rotate, thus generating traction force, so that the driving mechanism moves along the extending direction of the rail, and the driving mechanism pulls the ship to move through the second rope.
