Definitions
- the invention relates to a ventilation device for transmission with water-containing lubricant, which is connected to the transmission housing via a line, and having a pressure equalization opening leading into the environment.
- a vent is present, which allows for operational increase and decrease in temperature in the transmission pressure equalization with the environment and is usually equipped as a device with internals for retaining oil mist and to keep away dirt from the environment.
- WO 2007/098523 A1 discloses a water-containing lubricant which, together with a high proportion of water, contains a freezing-point depressant, for example glycol, and further additives or suspended solids. Further details and the advantages that can be achieved with such a lubricant can be found in the cited publication.
- DE Offenlegungsschrift 22 20 565 discloses a recirculating cooling system for oil lubricated reduction gears. A fan recirculates oil containing vapors from inside the transmission through a heat exchanger back into the transmission. The condensed oil is recycled separately. Pressure equalization with the environment does not take place.
- the venting device consists of at least one container which passes as a condenser to the evaporated water through the line and is provided with means for heat dissipation and from which the condensate passes back into the transmission.
- the device can also be arranged at the same height or lower than the transmission. Then the line leads at least in the container downwards and ends under the mirror of the condensate (claim 5). Thus, the condensate can be sucked back in case of pressure drop in the transmission.
- the device consists of two arranged in substantially the same geodetic height containers containing a liquid and their lowest points communicate with each other via a U-shaped channel, the line opens into one container and the other container above having the pressure equalization opening (claim 6).
- the two containers are connected together in the manner of a siphon. When pressure changes in the transmission, the liquid shifts in the siphon, wherein the liquid levels in the two containers apart move. Water vapor condenses in the liquid, part of which flows back into it when there is a sufficiently high level of liquid or falling pressure in the gearbox.
- the liquid in the siphon and in the two containers may be water (claim 8), a freezing point depressant, for example glycol, (claim 9) or a mixture of both. Depending on conditions and requirements, one or the other is preferable. If no temperatures are to be expected below freezing, water is preferable because it keeps the composition of the lubricating fluid in the transmission unchanged. Otherwise, the freezing point lowering agent is more advantageous.
- the liquid-filled space contains a porous material of high thermal conductivity (claim 10). This improves the heat transfer and the condensation and prevents oscillation of the liquid levels in the two containers. Has proven particularly useful as a porous material stainless steel wool (claim 11).
- Fig. 1 Schematic representation of the device according to the invention in a first embodiment
- Fig. 2 Schematic representation of the device according to the invention in a second embodiment, in the starting position
- Fig. 3 Like Fig. 2, when heating the transmission
- Fig. 4 As in Fig. 2, upon cooling of the transmission
- Fig. 5 Schematic representation of the device according to the invention in a third embodiment.
- a transmission is summarily with 1 and a ventilation device according to the invention denoted by 11.
- the transmission 1 contains here as a simplified example a driving shaft 6 with a gear 5 and a driven shaft 8 with a gear 7.
- a driving shaft 6 with a gear 5
- a driven shaft 8 with a gear 7.
- gearboxes such as storage and housing division is not discussed further. In practice, it may be any transmission, such as the manual transmission or the rear differential with a motor vehicle.
- a lubricating fluid 2 In the lower part of the transmission is a lubricating fluid 2 with the mirror 4.
- the gear 7 dips into the lubricating fluid 2 a.
- the transmission 1 In the upper region, the transmission 1 has an opening 9. Otherwise, it is closed, so has no flow connection to the environment.
- the lubricating fluid contains a significant amount of water and is described in more detail in WO 2007/098523 Al. From the opening 9 leads a line 10 steadily upwards to the ventilation device 11 according to the invention.
- This consists of a container 17, inside which a cooling coil 15 is located. It is traversed by a preferably liquid coolant. Alternatively or additionally, the container 17 may be externally provided with cooling fins 16. At its highest point, the container 17 has an opening 13 which protects against the ingress of dirt as a conventional vent with a hat 14.
- the venting device is formed by two containers, a first container 21 and a second container 22, both substantially at the same geodetic height, ie side by side.
- the rising from the transmission line 10 opens at a certain height (mouth 23) in the first container 21.
- the second container 22 has at its highest point a conventional vent that connects to the environment.
- the deepest points 25,26 of the two containers 21,22 are connected to each other via a U-shaped tube 27 so that they form communicating vessels for a liquid.
- the U-shaped tube 27 and the lower regions of the two containers 21,22 are filled with a liquid corresponding to the liquid levels 30,31.
- the space 28 or 29 above it contains air and water vapor.
- both mirrors 30, 31 are equally high.
- the mirror 30 is here slightly below the mouth 23 of the conduit 10.
- the liquid is one of the components of the lubricating fluid or the lubricating fluid itself or a mixture of their components.
- the U-shaped tube 27 and the lower regions of the two containers 21,22 still contain a filling 32 of a porous material that absorbs and conducts heat well. Although this filling 32 is intended to allow the flow of the liquid between the two containers 21, 22, but damp them. Above all, it has the task of absorbing and dissipating heat, see the functional description below. Stainless steel wool has proven to be particularly effective, not least because of its good thermal conductivity.
- the U-shaped tube 27 may be provided with cooling fins 33.
- the transmission heats up and with it the lubricating fluid, wherein the water contained therein begins to evaporate and the air / steam mixture begins to evaporate in the room above the lubricating fluid expands.
- This causes an increase of the mixture through the channel 10 into the space 28, in which it displaces the liquid present there first - causing a drop in the mirror 30 to 30 '- and in the sequence by the liquid in the U-shaped tube 27 pearls ,
- the water vapor - thanks to the contact with the filling 32 condenses very quickly - and the air reaches the second container 22.
- Fig. 5 differs from that of Fig. 1 in that the conduit 110 is guided in the container 117 so far down that its open end 123 is immersed in the water condensed 132. The end 123 is below the liquid level 130, so that when cooling the transmission condensate is sucked back into the transmission. As a result, there is great freedom in the arrangement of the container 117. It can be placed in the vehicle so that it is exposed to the wind, even near the ground.
