Abstract (en)
[origin: US4787318A] The traction bogie comprises two wheel sets each coupled with a traction motor. The bogie frame is mounted resiliently on the wheel sets with provision for movement at least lengthwise of the bogie. Each of the casings of the traction motors is carried on the associated wheel set and is connected to the bogie frame to be movable in three dimensions. Also, each casing is connected to the bogie frame by way of two links which are adapted to transmit traction and braking forces and which are articulated to the bogie frame and to the casing to be pivotable around substantially vertical axes. The links are so disposed that their longitudinal axes converge and the imaginary extensions of the longitudinal axes intersect one another at an intersection point disposed in the vicinity of the wheel set and casing. The intersection point determines the position of an imaginary vertical rotational axis around which the wheel set and the associated traction motor can pivot relatively to the bogie frame.
