Definitions

  • the invention is based on a support for a car body on a chassis, which has the features from the preamble of claim 1.
  • Such a support is known from DE 195 41 611 A1.
  • the one shown there Support includes a pendulum support and a fluid-operated piston-cylinder unit, with the help of which the distance between the chassis and the body is changed can be.
  • the pendulum support has a first support part, a second support part, which is arranged between the first support part and the chassis, and a third support part that is between the first support part and the car body is arranged. All three support parts are ring-shaped.
  • the piston-cylinder unit is forcefully inserted between the second support part and the chassis and is located essentially within the three annular support parts, so that it takes up little additional space in the axial direction and the entire support builds very compact.
  • the object of the invention is to provide a support with the features from Develop the preamble of claim 1 so that it is even more compact can build and the manufacturing cost is reduced.
  • This task is for a support with the features from the preamble of Claim 1 solved in that this support additionally with the features is equipped from the characterizing part of claim 1.
  • the first support part made of two identical individual support parts is formed, which, like a ring, has enough space between them Leave piston-cylinder unit, but opposite an annular first support part at a much lower cost of materials and at a much lower Lead space requirements.
  • the space that is not required for the first column part is available the second and the third support part.
  • the areas of the second support part and the third support part, which are the rolling surfaces are subject to special loads during operation. That is why favorable if the rolling surfaces on separate, in the second or third support part are used rolling elements. These are preferred at least superficially hardened.
  • Claim 7 also contains a particularly preferred further development, according to which Flow path for the inflow of pressure medium into and for the discharge of pressure medium leads out of the cylinder over the outer flange of the cylinder. This appears cheaper than guiding the flow path over the piston of the piston-cylinder unit, because the interface between the support and the car part preferably located on the piston.
  • the displacement sensor in the Support is integrated and which is a measure of the distance between the chassis and Car body representing relative position between the piston and the cylinder the piston-cylinder unit in the axial direction of this unit through the displacement sensor is detected. A very compact assembly is thus obtained.

  • a spring is provided which, for some reason, to Example due to a defect, unpressurized piston-cylinder unit piston and cylinder tries to push apart with a certain force and thereby ensures that even in such a case, the perpendicular to the axial direction of the piston-cylinder unit existing interlocking of different parts to each other, especially one Maintain a positive connection between the piston and a part of the carriage and knocks be avoided between the parts.
  • the spring is only effective in an emergency, so that it does not have to take part in the normal axial movement between the piston and the cylinder and can be relatively short.
  • the spring is housed within the piston so that a cavity within the piston is used to accommodate the spring. For the The spring is then little or no additional space in the longitudinal direction of the piston-cylinder unit needed.
  • the piston-cylinder unit provided with the reference number 60 in its entirety comprises a cylinder 61, which is open to the bogie 10, and a single-acting Plunger 62, which is guided in the cylinder 61 pressure-tight and in Direction towards the bogie 10 protrudes from the cylinder 61.

Radial a pressure medium channel leads through the plate 63 and axially through the plunger 62 65, a pressure chamber 66 between the plunger 62 and can be supplied to the cylinder 61 or removed from the pressure chamber.
  • the pendulum support provided with the reference number 12 in its entirety essentially comprises three parts, namely a middle, first support part 13, a second support part 14, which is arranged between the first support part 13 and the bogie 10 , and a third support member 15 which is between the first support member 13 and the Car body 11 is arranged. All three support parts 13, 14 and 15 are annular formed between the outer flange 64 of the cylinder 61 and the car body 11 arranged and surround the cylinder 61, which protrudes into all three support parts, radially at such a distance that the pendulum support 12 without interference from Cylinder-piston unit 60 the required angle can be deflected.
  • the second support part 14 has a hollow cylinder 70, the one of which is used as a rolling surface serving annular surface 17 on the outer flange 64 of the cylinder 61 facing end is designed as a circular cylindrical rolling surface 16, the axis of which is perpendicular to the axis of the hollow cylinder 70 and which runs on the flat rolling surface 17 of the outer flange 64 rests in a line and can roll on this surface.
