Abstract: A bogie with a torsion-soft corner-stiff frame for high speed rail vehicles with a wear-resistant means interconnecting the central areas of the longitudinal beams of the bogie together with one wear-resistant means each interconnecting the longitudinal beam ends. Of the wear-resistant means, that means which is located within the region of the vertical transverse plane is designed as an intermediate joint permitting movements solely about the y-axis, whereas the wear-resistant means at the ends form components of horizontal spring leaves which form head pieces of the bogie. The ends of said spring leaves are in a corner-stiff manner connected to stiff corner pieces arranged at the ends of the longitudinal beams.

Abstract: A bogie arrangement for self-propelled high-speed rail vehicles with at least two driving bogies supporting the vehicle body. Each of the driving bogies is powered by at least one electric motor and supports the vehicle body by a spring system while having a common pivot point with the vehicle body. The rotor of the fully spring-cushioned and transversely extending motor is operatively connected to the driving wheel set through the intervention of a transmission and a cardan quill shaft having elastic articulated bearings. The motor is held in the space between the wheel set axle and the vertical central transverse plane of the bogie transversely swingably on the understructure of the vehicle body. The longitudinally acting forces of the motor are transmitted by at least one link of considerable length from the housing of the motor to the adjacent frame section of the vehicle.
