Abstract (en)
[origin: EP2020355A1] The low building height bogie intended for low-floor vehicles especially trams is installed so that the side rotary bogie (1) is composed of one cradle (16a), always placed approximately in the middle of the bogie, and the middle bogie (2) is composed of two cradles (16b), of which each is situated between one pair of opposite wheels with common axis of rotation. The wheels (5) of the bogie (1,2) are fixed by means of pinned bearings of the axle (11), which are bent downwards in the middle part, whereas the axle (11) contains gaps (11a) intended for insertion of the primary springing system (6). The primary springing system (6) carries the bogie chassis (12a), (12b) in which there are gaps from below (12c) intended for insertion of the primary springing system (6).
