Abstract (en)

A single axle bogie (1) with independent wheels (3) has a bogie frame (2) provided with a pair of wheels independently drive by individual main motors (8). The motor speeds of the main motors are controlled to be equal. Between a vehicle body (5) and the bogie frame (2), a damper mechanism (10) comprising a lever (11), a damper (12) and side rods (13a,13b) is installed to restrain a turning motion of the bogie (1). Between the vehicle body and the bogie frame, a centering mechanism (20) comprising a lever (21), a centering device (22) and side rods (23a,23b) is installed to return the bogie (1) to a neutral position. Thus, hunting (yawing oscillations) during a high speed run is suppressed to achieve a stable run. <IMAGE>
