Definitions

  • the invention concerns first a procedure for the circulation of a quantity of oil in accord with the generic concept of patent claim 1 and second an oil circuit for a transmission in accord with the generic concept of claim 2 .
  • Oil which is in circulation in a motor vehicle transmission, exhibits temperature related viscosities, wherein a high viscosity at low temperatures leads to increased friction in the gear train, increased power consumption by the pump and a degradation of the efficiency of the drive action of the motor vehicle while the warm-up phase lasts.
  • the proposition has already been made to warm the oil more rapidly in an oil circulation system, in order the shorten the heating phase and to reach a more favorable efficiency.
  • the said porous medium can be optionally placed in the course of the circulation, but most favorably within the transmission housing and/or in the oil pan.
  • the advantage arises in connection with the invented storage medium, that an optionally given amount of cold oil is held out of circulation, until it has reached a sufficient temperature.
  • the porous storage mass can be in an optional shape, for example, placed in the oil pan on the bottom or on the sides and in that place fulfill its temporary, temperature conditioned, storage and retention functions for the oil.
  • the size of the pores is so selected, that the storage medium can accept “thick” oil easily. “Thinner” oil, i.e., heated oil, will be released from said porosity of the storage medium without significant resistance.
  • the storage medium can be made of various materials, which exhibit specific porosity or permeate retention. These materials could be, for example, foamed metal, or woven stranded metal, or a feltlike substance. Ceramic and plastic substances are also possible, directly as porous materials or again woven.
  • the storage medium can have an elevated hollow space portion, wherewith the advantage of a small internal reservoir, i.e., additional storage space is available.
  • the storage medium can undertake additional functions, namely those of an oil filter, heat insulation or body noise abatement.
  • the latter can especially be achieved, in that the oil pan and/or parts of the transmission housing can be internally lined with the said storage medium. With such a lining, the advantage of loss of heat during the heating-up phase and the emission of noise is still retained.
  • FIG. 1 exhibits an exemplary, partial component of a complete oil circulation system, the complete system not being shown.
  • an oil pan 1 this being a supply tank for refluxed oil.
  • the part of the complete system can be for an automatic transmission with a circulation system for oil serving both lubrication and hydraulic pressure purposes.
  • the oil pan 1 the oil is shown at an oil level 1 a.
  • the oil pan possesses a bottom 1 b and an oil exit line 2 extending therefrom.
  • the oil is removed from the exit line 2 by a pump 3 and injected into the additional circulation system 4 (not shown).
  • the oil is returned from a transmission exit through an oil return line 5 , thereby regaining its storage in the oil pan 1 .
  • a solid body made of a porous storage medium 6 is found in place, this being generally a foamed metal, which has a high effective space portion and is thus in a position to accept and store the incoming oil.
  • the storage medium 6 is here, as an example, depicted as a somewhat rectangular sided block and supports itself on two feet, namely 7 , 8 , on the bottom 1 b of the oil pan 1 .
  • the storage medium 6 lies, thus not directly on the bottom 1 b, but is available for oil contact on all sides, even with oil flowing therebeneath.
  • Another arrangement of the storage medium 6 could be considered, wherein an inner cladding of the oil pan 1 with a layer of the storage medium 6 material. Thereby, it is possible that both heat insulation of the oil pan 1 is acquired and noise radiation is prevented.
  • the function of the storage medium 6 is as follows: Upon a cold start of the internal combustion motor of the vehicle, cold viscous oil is found in the oil pan 1 , which flows only with difficulty. A part of all the oil, which is intended to be circulated, is found in the storage medium 6 .
  • the pump 3 transfers only that oil which is to be found outside of the storage medium 6 , that is to say, the pump moves a portion of the oil into the oil circulation system 4 , from which the portion returned, now at an elevated temperature, reenters the oil pan 1 through the return line 5 . In this way, the resident oil in the oil pan 1 is heated. This heat is then immediately transferred by conduction and convection to the oil in the storage medium 6 .
  • the oil in the storage medium 6 then becomes more fluid, which allows it to preferentially leave the storage medium 6 and enter into the supply of oil to the pump 3 to join the general circulation of oil. Thereby, successively, more and more of the oil retained in the storage medium 6 mixes into the circulating oil and is heated.
  • the respective oil, which has been circulating through the transmission thus reaches its operating temperature more rapidly, so that the transmission can operate earlier with a better efficiency.
  • the storage medium 6 is not only fully surrounded by the oil flow, but to a certain degree is subjected to a through-flow of oil, whereby it provides an oil filtering function simultaneously. That is to say, the contaminate particulate in the oil is retained by the porosity of the storage medium 6 .
