摘要：
A bogie (10), in particular for railway platform cars, comprising a swinging transom (11) with a rotating central portion connected, by means of a fifth wheel (12), to a body (13) of the vehicle.
The swinging transom (11) has opposite ends (14) generically shaped in the form of an overturned L which each fit over a box-shaped element (16) connected to it by means of suspensions (15).
The two box-shaped elements (16) are connected to each other by a frame (17) laterally surrounding the fifth wheel (12), and each comprising two generically U-shaped arms (18).
Each U-shaped arm (18) carries a wheel (19) independently driven by its own motor (25) and is fitted from above with couplings (20) to connect it to a primary suspension (21) horizontally disposed on the upper surface of the box-shaped elements (16).
