Definitions

  • the invention relates to a bogie for rail vehicles, the bogie being equipped with a primary suspension.
  • Bogies are generally equipped with primary springs made of steel in the form of coil or leaf springs or rubber in the form of elements that are subjected to shear or pressure loads and are homogeneous or stiffened with a metal insert.
  • the individual spring elements have a linear or weakly progressive characteristic. A clear progression can be achieved by gradually switching on additional spring elements, whereby a discontinuity in the characteristics is accepted. Rubber springs tend to settle, which can only be countered by sufficient volume with a corresponding space requirement.
  • the security against derailment of a bogie can be guaranteed by a suitably soft design of the primary spring or by the design of the frame in a torsionally soft form or as an articulated frame.
  • the mechanical coupling of spring groups via connecting levers to implement a three-point bearing is no longer important for reasons of weight and space.
  • the object of the invention is to provide a bogie To create primary suspension, the characteristics of which are variable with unchanged installation space, which can be adjusted in height without additional elements and which allows a three-point bearing to be implemented in a two- or multi-axis version in a simple manner.
  • the primary suspension is designed with hydropneumatic spring elements consisting of cylinders and pistons with assigned liquid and gas volumes, at least part of the liquid volume being arranged in the spring elements.
  • the height of the spring elements can be regulated by refilling or draining the liquid.
  • the spring elements are advantageously damped, e.g. in the form of a throttle on the piston or at the transition to lines connected to the spring elements.
  • the gas volume can be arranged in the spring elements, or gas storage devices are connected to the spring elements as external elements, a part of the liquid volume and the gas volume being arranged in the gas storage devices.
  • both spring elements of a wheel set or idler gear pair or both spring elements of a bogie side can be connected to one another via a line.
  • the spring elements 1, 3 of a bogie are shown here, the upper spring elements 1 being arranged on one bogie side (longitudinally) and the lower spring elements 3 being arranged on the other bogie side.
  • All spring elements 1, 3 consist of a cylinder 2 and a piston 8 guided therein and act on a hydropneumatic basis. While the upper spring elements 1 are connected to one another via a connecting line 15 and a common gas storage unit 2 is connected to this connecting line 15, the gas storage unit 2 is integrated into the lower, separately arranged spring elements 3.
  • the damping valves 9, 10 are different, namely in the case of the connected spring elements 1 at the transition to the connecting line and in the separate spring elements 3 on the piston.
  • the separate spring elements 3 have a gas and oil filling 5, while the connected spring elements 1 have separate gas and oil fillings 6, 7. All spring elements 1, 3 have vents 4.
