A running gear unit for low-floor rail vehicles includes a running gear frame on which individual wheels are rotatably mounted through a respective rocker and the rocker is articulatingly attached and supported by primary springs. The running gear frame is connected to a car body of the low-floor rail vehicle through two articulated rods having one end being articulatingly mounted at a distance from one another on a crossmember of the running gear frame and another end being likewise articulatingly attached to the car body. The car body is supported on the running gear frame through secondary springs being mounted in pockets near transverse ends of the crossmember. Transverse stops are disposed at a distance from one another in the crossmember for limiting transverse movement of the car body relative to the running gear unit. In order to construct the running gear unit in such a way that the floor area in the car body is at a continuous low level and the wheels of the running gear unit can be steered, the rocker is mounted on a horizontal axle disposed in the transverse direction of the running gear unit, on a bolster which is articulatingly secured about a vertical axis on the running gear frame.

Running gear unit for low-floor rail vehicles

A running gear for drop-frame rail vehicles includes a running-gear frame on which individual wheels are each rotatably mounted through a respective rocker and the rocker is fastened in an articulated manner and supported through primary springs. The connection of the running-gear frame to the carriage body of the drop-frame rail vehicle is provided through two articulated rods which are mounted on a crossmember of the running gear frame and which are fastened to the carriage body. The carriage body is supported on the running-gear frame through secondary springs which are mounted in pockets of the transverse ends of the crossmembers. Transverse stops which are disposed in the crossmember limit the transverse movement of the carriage body in relation to the running gear. Advantageously, the individual wheel and the drive of the individual wheel are mounted in the rocker in such a manner as to be connected to form a structural unit. This structure provides running gears for drop-frame rail vehicles in which the drop-frame nature of the carriage body is completely preserved and only wheel cases are present in the region of the individual wheels of the running gear.
