Abstract
The cross-coupling connects the two trucks of the vehicle together and employs a torsion shaft which is mounted on the vehicle body with torsionally stiff levers. The cross-coupling also has a shaft mounted on each truck with a pair of torsionally stiff arms. The innermost arms of the shafts are articulated via a hinged rod to an associated lever of the torsion shaft while the outermost arms are articulated through a rod to the vehicle body. In addition, piston cylinder units are provided for damping the rotational movements of the trucks relative to the body as well as independent damping means for damping the transverse movements of the vehicle body relative to the trucks.
Claims8
A rail vehicle comprising
- a vehicle body;
- a pair of trucks rotationally and transversely supporting said body thereon;
- and
- a cross-coupling connecting said trucks together, said cross-coupling including
- a torsion bar mounted on said body and extending longitudinally of said vehicle body,
- a pair of torsionally stiff levers, each said lever being disposed at a respective end of said torsion bar,
- a pair of shafts, each said shaft being mounted on a respective truck in parallel to said torsion bar,
- two pairs of torsionally stiff arms, each said pair of arms being disposed on the respective ends of each said shaft,
- a first pair of rods, each said rod being hinged to and between an innermost arm of said pair of arms on a respective truck and one of said levers on said torsion bar, and
- a second pair of rods, each said rod of said second pair of rods being articulated to and between an outermost arm of said pair of arms on a respective truck and said vehicle body.
