Definitions

  • the present invention relates to a housing for a hydraulically assisted rack and pinion steering gear for vehicles, comprising a rohrformigen cylinder and with a Zitzelventilgehause and with hydraulic channels for supplying hydraulic fluid in and out of the working spaces of the cylinder, wherein the housing has a top and a bottom.
  • the object of the present invention is to provide an alternative system in which the gases in the hydraulic medium can at least partly accumulate outside the tubular cylinder.
  • the inventive housing is advantageously characterized by the fact that only one hole must be introduced into the housing.
  • a channel part is inserted, which is secured captive in the housing.
  • the bore or the channel part form a space that is above or above. higher than the highest point of the cylinder resp. is disposed of the respective working space, so that located in the idle state of the system in the hydraulic medium gases can accumulate there.
  • the discharged Olstrom will then draw the gases accumulated in the room with out of the housing, whereby a sufficient ventilation of the system is ensured.
  • the shape of the space, which is formed above the cylinder can be adjusted by the design of the channel part or an additional part which rests between the bottom of the blind bore and the channel part as desired. It is optionally possible, the additional part of the channel part z.
  • the channel part can be made of metal or plastic.
  • Fig. 1 A cross-sectional view through the housing according to the invention without inserted channel part;
  • Fig. 2 section through a first embodiment of the channel part for use in a housing acc. Fig. 1 ;
  • Fig. 3 fully assembled housing acc. Fig. 1 with channel part gem. Fig. 2; Fig. 4: second embodiment;
  • FIG. 1 shows a first embodiment of a housing 1, which with its housing wall forms a cylinder 2 in which a piston rod 3 rests.
  • the cylinder 2 forms with its inner wall 5 together with the piston, not shown, at least two working spaces, in the hydraulic medium by channels and can be brought out.
  • the housing 1 is formed thickened at its right upper side 7, so that a bore 6 in the housing 1 can be introduced.
  • the housing 1 has an upper side 1a and a lower side 1b.
  • the cylindrical wall 5 of the cylinder 2 is pierced by the bore 6, which is designed as a blind bore, whereby a connection between the bore 6 and the cylinder 2 is formed, which is referred to below as the window-like opening 2a.
  • the bore 6 can more or less cut the cylinder.
  • the diameter of the bore 6 determines the maximum cross section of the supply and discharge channel.
  • the housing 1 has, in the region of the bore 6, a bore 8 with a larger diameter, the inner wall of which can be provided with an internal thread for screwing in a coupling part.
  • the channel part 10 (FIG. 2) is designed as a rod-shaped part which has an axially extending channel 13 which exits the channel part 10 through the one end face 16. At its one end, the channel part 10 has an end wall 14. The other end has an outwardly directed collar 15.
  • the cylindrical wall 11 of the channel part 10 further has a window-like opening 12, which is in communication with the channel 13 and forms a space IIa.
  • FIG. 3 shows the housing 1 with the channel part 10 mounted thereon.
  • the channel part 10 should, if possible, fit exactly into the bore 6 fit, so that hydraulic medium between the channel part 10 and the inner wall of the bore can not penetrate. E- ventuell additional seals (not shown) are provided. By the collar 15 of the channel part 10, this can be securely held by a screwed into the bore 8 Ankoppelteil in the housing in position.
  • the channel part ver ⁇ closes the window-like opening 2a with its cylindrical wall 11 in the lower region, and extends to Mög ⁇ probability at least up to the top point 17 of the cylinder 2.
  • the window-like opening 12 of the channel part adjacent to the uppermost dot 17 at so that it is ensured that the gases collecting at the top point can pass through the opening 12 into the space IIa.
  • the channel member 10 can not rotate about its axis of rotation, whereby the window-like opening 12 evtl. no longer communicates with the interior of the cylinder 2, a rotation is recommended.
  • This can, for. B. be ensured by a positive engagement, which is formed by the corresponding configuration of the outer contour of the channel part and the inner contour of the housing.
  • the housing 1 is almost identical to the housing of the above-described figures. Only the bore 6 ends just as far above the uppermost point 17 of the cylinder 2, that it is ensured that the gases collecting at the highest point reach the bore 6.
  • the channel part 10 is shorter than the channel part acc. Figure 2, so that it forms the collecting space 6a together with the bore 6.
  • the duct part is a tubular part resp. formed as a sleeve which has an axial channel 13 which emerges at the end face 18a.
  • the wall 11 of the channel part closes the broken by the bore 6 cylinder wall only in the lower region and, together with the cylinder inner wall 5, an opening 18 which connects the cylinder interior with the plenum 6a.
