Definitions

  • the present invention relates to a hydraulic device for a rail vehicle according to the preamble of claim 1.
  • Generic hydraulic devices are used to control or regulate a hydraulic flow for different components of a rail vehicle.
  • Such hydraulic devices essentially consist of a liquid container or tank for storing a hydraulic liquid, a motor with a pump for conveying the hydraulic liquid from the liquid container into the control plate, a control plate and a control area.
  • the hydraulic device also has an aeration and venting unit for aerating and venting the liquid container.
  • the control plate itself accommodates the hydraulic circuit and the necessary components.
  • the control area and the liquid container are usually arranged on opposite sides of the control plate.
  • the air pressure in the liquid container must be within a permissible pressure range when the liquid, in particular hydraulic oil, is being supplied or removed during operation of the hydraulic system.
  • the liquid must not escape from the liquid container to the outside.
  • the aeration and ventilation unit is usually attached at the highest point of the liquid container.
  • the problem with this arrangement of the aeration and ventilation unit is that, when the aeration and ventilation unit is integrated into the control plate, space is required for the components required for this within the control plate.
  • the object of the present invention is to provide a hydraulic device that is compact in design and ensures reliable ventilation.
  • the hydraulic device according to the invention for a rail vehicle has a liquid container, a motor with a pump, a control plate, a control area and a ventilation unit for ventilation and ventilation of the liquid container.
  • the ventilation unit has a valve unit integrated into a wall of a housing of the liquid container and a channel labyrinth which is arranged in the liquid container and is connected to the valve unit.
  • the ventilation unit does not take up any space in the control panel.
  • the liquid container can be of compact construction, since the encapsulation of the valve unit in the liquid container can be constructed to save space than a ventilation unit connected to the liquid container outside of the liquid container.
  • the channel labyrinth is installed in an interior space of the housing of the liquid container which is enclosed by the housing.
  • the channel labyrinth is integrated into at least one wall of a housing of the liquid container.
  • At least one channel of the channel labyrinth opens into an interior space of the liquid container enclosed by the housing in the uppermost region of the housing when the liquid container is installed.
  • connection of the channel labyrinth to the valve unit thus enables the liquid container to be vented in a simple manner.
  • At least one channel of the channel labyrinth opens into an opening in a housing base of the housing that is open to an outer space of the liquid container that surrounds the housing.
  • This opening in the bottom of the housing and the labyrinth channel connected to it and opening into the valve unit allow the liquid container to be aerated in a simple manner.
  • At least one of the channels of the channel labyrinth is embedded in a wall reinforcement of a housing wall of the housing.
  • the valve unit has at least one check valve.
  • valve unit has at least one membrane valve, in particular with a semi-permeable membrane.
  • membrane valve in particular with a semi-permeable membrane.
  • sintered filter is also conceivable.
  • top, bottom, left, right, front, rear, etc. refer exclusively to the exemplary representation and position of the hydraulic device, the liquid container, the control plate, the control area, the loading and ventilation unit, the channel maze and the like. These terms are not to be understood as limiting, i.e. these references can change due to different working positions or the mirror-symmetrical design or the like.
  • the hydraulic device 1 essentially has a liquid container 2, a control plate 4 arranged on an outer surface of the liquid container 2 and a control area 3 arranged on the side of the control plate 4 facing away from the liquid container 2 Protective cap 7 is covered to the outside.
  • the hydraulic device 1 also has a motor, not shown here, with a pump, which serves to hydraulically stored in the liquid container 2 To pump liquid, for example a hydraulic oil, into the control plate 4.
  • a motor not shown here
  • a pump which serves to hydraulically stored in the liquid container 2
  • liquid for example a hydraulic oil
  • the liquid container 2 also has, as shown in FIGS Figures 5 - 7 is shown, a liquid inlet 29 and preferably two sight glasses 26 and 27 for checking the liquid in the liquid container.
  • the hydraulic device 1 also has a ventilation unit 5 for ventilation of the liquid container 2 .
  • This ventilation unit 5 has a valve unit 51 integrated into a wall 22 of a housing 21 of the liquid container 2 and a channel labyrinth 52 connected to the valve unit 51 .
  • the channel labyrinth 52 is integrated into at least one wall 22 of the housing 21 of the liquid container 2 .
  • the Figures 5 and 6 such a channel 53 in a rear wall 22 of the housing 21 of the liquid container 2. How well in 6 As can be seen, this channel 53 extends from a valve unit 51 built into the rear wall 22 near the bottom 23 of the liquid container 2 along the wall 22 of the housing 21 to an upper front edge of the housing 21.
  • Another channel 53 leads to an opening 54 that is open to an interior space 25 of the housing 21 of the liquid container 2.
  • channel labyrinth 52 is incorporated in a wall reinforcement 28 in the area of the base 23 of the housing 21 of the liquid container 2 and opens into an opening 55 in the housing base 23 of the housing 21.
  • This part of the channel labyrinth 52 which also opens into the valve unit 51, enables the liquid container 2 to be aerated when the valve unit 51 is switched accordingly.
  • the ventilation unit 5 has a first labyrinth of channels for ventilation and a second labyrinth of channels for ventilation.
  • the attachment of the channels 53 in the housing walls 22 shown here or in a wall reinforcement 24 of a housing wall 22, as in the Figures 5 and 6 shown is to be understood here as an example.
  • the channels 53 are introduced in different areas of the housing walls 22 or the housing base 23.
  • the valve unit 51 preferably has at least one check valve 57, as shown by way of example in 4 is shown.
  • the valve unit 51 preferably has two check valves connected in opposite directions.
  • Spring-loaded, seat-tight valves with an elastomer or metal sealing geometry, such as a ball or conical seat, are preferably used as check valves.
  • An elastomer membrane, for example, is used as the elastomer.
  • valve unit 51 as a diaphragm valve, in particular with a semi-permeable diaphragm, is also conceivable.
  • the use of sintered filters is also conceivable.
  • valve unit 51 When the valve unit 51 is used as a membrane filter, the air pressure in the interior 25 of the liquid container 2 is adjusted to ambient air pressure.
  • valve unit 51 designed as a membrane or sintered filter, but not the larger molecules of the liquid stored in the liquid container 2, in particular oil molecules.
  • liquid container 2 in several parts, with a universal container with a first housing, which is adapted to a required minimum volume of liquid and air and, if necessary, can be supplemented by one or more housing constructions.
  • the channels 53 of the channel labyrinth 52 can be designed as cavities in the housing 21 or also as tubes.
