ABSTRACT:
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.
