A bearing for mounting an anti-roll bar on a bogie frame, the anti-roll bar extending along an axis transverse to the bogie and being mobile in rotation relatively to the frame around the axis, the bearing including a first half-shell, and a second half-shell adapted so as to be attached on the first half-shell by means of a first attachment system, the first half-shell and the second half-shell then forming a housing crossing through along the axis and adapted for receiving the anti-roll bar. The first half-shell is distinct from the frame and adapted so as to be attached on the frame by means of a second attachment system.

The invention relates to a bogie (1) for a guideway-bound levitation vehicle (7) of a magnetic levitation system, with two rows (21, 22) of multiple levitation frames (2) spaced apart from each other in a transverse direction (Y) of the bogie (1) and extending in a longitudinal direction (X) of the bogie (1), with at least two cross members (3) spaced apart from each other in the longitudinal direction (X) and extending in the transverse direction (Y) and connecting the two rows (21, 22) of multiple levitation frames (2) to each other, with at least one longitudinal member (4) extending in the longitudinal direction (X) and connected to the cross members (3), and with at least one receiving means (18) for receiving a vehicle compartment (8) of the levitation vehicle (7). According to the invention, two longitudinal members (4) spaced apart from each other in the transverse direction (Y) are arranged between two cross members (3) spaced apart from each other in the longitudinal direction (X) and are connected to these two cross members (3) The invention further relates to a bogie.

A coupling includes a claw part and an intermediate piece. The intermediate piece includes a tube piece produced from aluminum or from an aluminum alloy, and a buffer part received in an end region of the tube piece and including elastic damping elements for receiving the claw part. The damping elements are surrounded by the end region radially at an outside in a circumferential direction. The buffer part includes a part which is different from the damping elements and is produced from a material of a brittleness which is greater than a brittleness of the tube piece.

A traction mechanism, a bogie assembly and a straddle-type monorail vehicle are disclosed. The traction mechanism comprises: a traction component, comprising a transmission shaft and a traction connecting rod, the transmission shaft and the traction connecting rod being connected, the transmission shaft being suitable to be rotatably connected to a vehicle body, and the traction connecting rod being suitable to be hinged to a bogie frame; and a traction crank, both ends of the traction crank being suitable to be respectively hinged to the bogie frame and the vehicle body. The traction mechanism of the present disclosure has a simple and compact structure, and a transmission path of a traction force is short. The traction mechanism is convenient to assemble and disassemble, occupies a small space, is wide in usage range, can be used for low-floor and high-floor vehicles, and is also applicable to a single-axle bogie, a double-axle bogie and a multi-axle bogie.

A bogie is capable of being moved from a rest configuration to an active configuration in which the bogie carries at least one vertical load. The bogie includes a chassis, at least one pair of wheels, and a shaft extending along an axle axis for each pair of wheels. Each wheel has a wheel hub extending along a hub axis and an axle box attached to the chassis and receiving the associated hub. Each hub is rotatable relative to the associated axle box. For each hub, the hub axis forms a non-zero camber angle with the axle axis of the associated shaft when the bogie is in the rest configuration.
