SINGLE AXLE BOGIE FOR ROLLING STOCK

摘要

PROBLEM TO BE SOLVED: To provide a single axle bogie for rolling stock suitable for a low floor type streetcar wherein an overall structure can be simplified, miniaturized and lightened even in a case of providing a driving part and attaching loose wheel parts provided with wheels movably mounted on a track to a bogie frame so that they can be steered, and the wheels can be smoothly steered even along a tightly curved railway with a small minimum turning radius. SOLUTION: The loose wheel parts 5 provided with the rotatable wheels 5a on one ends of casings 6a are provided to horizontally turn on both sides of the bogie frame 2 via king pins 11. A plurality of support arms 16 is radially extended from the casings 6a of the loose wheel parts 5. A roller 19 is rotatably attached to each support arm 16 tip. Support plates 20 are respectively provided so as to protrude toward the rollers 19 from the bogie frame 2. Each loose wheel part 5 is composed to horizontally turn and not overturn by turnably supporting a corresponding roller 19 on a rolling contact surface 20a of each support plate 20.
