Abstract
A bogie includes two pairs of wheels (2), the wheels (2) of one pair being connected to one another by a shaft to form an axle (4), the axles (4) being connected to one another by a chassis (6) having at least two side members (10) resting on axle boxes (14, 14′) of each axle (4). The boxes (14, 14′) are arranged between the wheels (2) of the axle (4), and a motor (24) fixed to the chassis (6) extends between the wheels (2) of the axle (4) and drives the axle (4) in rotation by way of a coupling (42) and a reducing gear (28). One of the axle boxes (14) accommodates the reducing gear (28) of the motor (24).
