A new type of traction bogie for high-speed traction vehicles has been developed. The traction motors, gearboxes, hollow-shaft drives and disc brake systems were combined in such a way that their masses are largely allocated to the coach body. Thus the unsprung masses, consisting of the wheelsets and 50% of the primary suspension only and the primary suspended masses, are minimized.
The new bogies were tested on the high-speed train IC-Experimental and proved at speeds up to 406 km/h DB's new Hannover-Würzburg line.
The design of the IC Express was not changed with respect to elements important to running behaviour.
Additional changes were made to the bogie design to test steps to optimize the high-speed curving performance. They run in curves with a radius of 500 m (4°) with an unbalanced acceleration of 1.8 m/s2 (275 mm cant deficiency) and on straight tracks with 300 km/h.
The results of measurements are shown to compare the results of calculations of wheel loads carried out before testing with the results obtained during actual test runs. These test runs established the good performance of the new type of traction bogie. They proved that the low level of guiding forces and the stable running would allow still higher speeds.
