• a bogie is a drive of a rail vehicle in which two or more wheelsets are spring-mounted in a frame be able to twist in curves opposite the car body. This so-called double turntable steering made ⁇ light the construction of longer vehicles or route interpretation of the rails with a tighter turning radius.
• Modern bogies have a double suspension.
• the wheelsets are sprung by the so-called Primärfede ⁇ tion against the bogie frame.

• a sine wave occurs in wheel-rail systems with conically profiled and rigidly coupled wheels, in which the wheel profile tapers to the outside. In curves, the outwardly offset wheel rolls on the rail to a greater extent than the track offset wheel. It remains behind the outer wheel so that the axle turns into the bend.
• a sinusoidal running occurs in this case at a deviate ⁇ monitoring of the rail guide of racing line, which more than compensated for by the Radprofiltechnik and thus lead to a rolling movement.
