Abstract: 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.

Abstract: The coupling arrangement includes a longitudinally extending shaft, means for supporting the shaft on the vehicle body and a linkage which connects the trucks to the shaft. Each linkage employs a transverse steering rod which is articulated to the end of a truck at a predetermined connection point which lies in an inclined plane passing through a guide member connecting the truck to the vehicle body and through a transverse center plane of the vehicle body.

Abstract: The structural arrangement relates to a steering apparatus for rail vehicles which have a vehicle body, at least two trunks movably mounted to the body, at least two sets of wheels rotatably mounted in each truck by lateral wheel bearings. At least one of the set of wheels must be mounted for rotation about a vertical axis. In the steering apparatus, there are at least two guide rods pivotally mounted around the circumference of at least one of the wheel bearing housings. One of the guide rods is pivotally mounted to the truck and the second guide rod is pivotally connected to a positioning lever which is pivotally mounted to the vehicle body.
