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 level control system for a vehicle, in particular a rail vehicle, includes at least one level control cylinder and one level control piston, the level control piston being movably guided in the level control cylinder in order to adjust the level of the rail vehicle, the level control piston having an outer piston sleeve and a piston main body at least partially accommodated in the piston sleeve, and the piston main body being slidable relative to the piston sleeve for wear readjustment and being lockable and/or fixable in at least two adjustment positions.

A levelling system for a vehicle, in particular a rail vehicle, includes at least one levelling cylinder and a levelling piston. The levelling piston is at least partially provided in the levelling cylinder in a movable manner for setting the level of the rail vehicle. Further, the levelling system includes at least one guiding element, which is arranged within the levelling piston and partially protrudes from the levelling piston into at least one recess of the levelling cylinder such that an end stop in a longitudinal direction is provided for the relative movement between the levelling piston and the levelling cylinder.

Vehicle guidance system that includes a first guidance bogie selectively positionable in a first position for travel and a second position for direction change and a second guidance bogie selectively positionable in a third position for travel and a fourth position for direction change. At a common crossing, one of: the first guidance bogie is selectively positioned into the second position, or the second guidance bogie is selectively positioned into the fourth position.

A transaxle of a rail vehicle includes: a power assembly; an axle body; a running wheel; a guiding frame; a horizontal wheel; and a connecting rod component, including a first transverse pull rod and a second transverse pull rod, where when the rail vehicle turns left, the horizontal wheel cooperates with a rail beam to drive the guiding frame to swing and drive the first transverse pull rod to move together, and the second transverse pull rod is driven by the first transverse pull rod to drive the running wheel to swing to the left, and when the rail vehicle turns right, the horizontal wheel cooperates with the rail beam to drive the guiding frame to swing and drive the first transverse pull rod to move together, and the second transverse pull rod is driven by the first transverse pull rod to drive the running wheel to swing to the right.

A method for controlling a position of a floor of a carriage of a railway vehicle moving on rails, relative to a platform. The carriage includes a body including the floor, at least one bogie, and at least one suspension interposed between the body and the bogie. The method includes determining a level difference between the actual position of the carriage relative to the platform and an expected position of the carriage relative to the platform, adjusting a height of the suspension for compensating the determined level difference. Determining the level difference includes capturing an image of at least one predetermined pattern comprised on the platform with a camera borne by the body, comparing the captured image with a memorized reference image of the at least one pattern of the platform, and calculating a vertical displacement from the images to determine the level difference.
