Definitions

  • the invention relates to a buffer for rail vehicles according to the preamble of Claim 1.
  • buffers also known gas-hydraulic buffer.
  • These buffers are gas-hydraulic Damping usually from a closed cartridge, which as finished Component is inserted into the buffer such that the buffer plunger on the gas-hydraulic Damping element is supported on the buffer sleeve.
  • gas-hydraulic buffer in which the gas-hydraulic damping device is integrated into the buffer, so no actual cartridge is used comes.
  • Such a known buffer has a on the rail vehicle to be attached buffer sleeve and a buffer ram with an external Pusher tube, an inner plunger tube and a buffer plate on. The pushrod becomes guided on the outside of the buffer sleeve.
  • Both the ram and the tube Plunger tube are in operative connection with the buffer plate.
  • the plunger tube is double-sided each closed by a flange. In its interior, the plunger tube forms a Gas space for receiving a pressure of approx. 10-20 bar Gas and a subset of the hydraulic medium.
  • the buffer sleeve is in the Buffer plate facing end portion provided with an annular groove in which a V-shaped seal is added. This seals the gap between the plunger tube and the buffer sleeve and thus also the oil space to the outside.
  • the buffer has a buffer sleeve (not shown) to be fastened to the rail vehicle 1 and a plunger assembly 2.
  • the latter consists of an outer one Pusher tube 3 with an attached buffer pad 4 and an inner plunger tube 5.
  • the plunger tube 5 is closed on both sides by a respective flange 6, 7.
  • a gas chamber 8 for receiving a below an overpressure of about 10-20 bar standing gas and a subset of Hydraulic medium.
  • an oil chamber 9 is formed in the interior of the buffer sleeve 1. In the rebounded state shown here, the gas space 8 to a Part filled with hydraulic oil while the oil chamber 9 is completely filled with hydraulic oil is.
  • the vehicle-side valve flange 7 forms together with a recorded therein Valve assembly 13, a gas-hydraulic control device 12, which the plunger assembly 2 endeavor to keep in the rest position shown here. moreover is acted upon by the gas-hydraulic control device 12 on the buffer plate 4 Shock forces the flow between the oil chamber 9 and the gas space 8 in Controlled dependence of the acting forces. Because the basic mode of action the control device 12 is known, will not be discussed in detail.
  • This wire 19 is used first Line as an assembly aid, by means of which the intermediate element 15 on the disc 10 and so that it is fixed to the plunger tube 5. Furthermore, the bracket 20 also serves as a positioning aid, which the angular position of the plunger tube 5 about the longitudinal central axis 22 in relation to the buffer plate 4 and thus determines the entire buffer.
  • the buffer sleeve 1 wrapped around the circumference plastic bands 27, which form a kind of plain bearing for the ram pipe 3.
  • the plunger tube 5 is largely parallel to Inserted longitudinal center axis 22 of the ram tube, as an eccentric deflection the buffer plate 4 of the "floating" between the buffer plate 4 and the Washer 10 mounted intermediate member 15 is received by facing each other the buffer plate 4 automatically centered in the radial direction.
