Definitions

  • Certain motor vehicles today are equipped with a device for distributing oil in relation to their drive shafts.
  • the oil is used for lubricating and cooling vehicle components which cooperate with drive shafts, e.g. a central gear and planetary gears associated with the vehicle's powered wheels.
  • the oil pipe runs between the gear housing and the cover and leads the oil from the gear housing to the cover in order therein to lubricate the planetary gear.
  • the oil pipe is configured in the shaft journal and runs in relation to the drive shaft.
  • the cover rotates when the vehicle is in motion, causing part of the oil present in the cover to be pressed against the inside of the cover and to form thereon an oil film.
  • a wiper fitted to shaft journal and situated in the cover comprises a blade which wipes oil off from the inside of the rotating cover.
  • the wiper comprises also a passage adapted to leading the wiped-off oil to the shaft journal.
  • the shaft journal is configured to lead the oil supplied by the wiper back to the oil bath in the gear housing.
  • Another object of the present invention is to propose a device for distributing lubricant which makes effective transfer of lubricant possible between a lubricant bath of a central gear and a planetary gear associated with the vehicle's powered wheels without involving modification of a shaft journal situated between them.
  • a further object of the present invention is to propose a robust device for distributing lubricant in relation to a motor vehicle's powered wheel shafts.
  • the lubricant is transferred by force of gravity from the lubricant bath to the cover, resulting in no need for a pump such as that described in prior art (see US 5,535,850).
  • the device according to the invention therefore represents a cost-effective solution to the above problem.
  • the device for distributing lubricant according to the invention may be installed in the vehicle during the manufacture of the vehicle.
  • a purchaser of the vehicle may thus have the option of choosing a vehicle with larger drive shafts and associated lubricant distribution devices.
  • the cover 240 rotates and the lubricant is pushed out by rotational force towards the inner surface of the cover 240.
  • the lubricant film thus formed is continuously wiped off by the wiper 270, which leads the lubricant through the duct 272 in the wiper to the space P2 between the shaft journal 230 and the sleeve 280.
  • the element 255 prevents the lubricant from the wiper 270 from being led from the space P2 into the space P1 in the cover 240 (see Figure 2). Instead, the lubricant runs from the space P2 back to the lubricant bath 205 (see arrows pointing left in Figure 2) via the outside of the sleeve 280 and the inside of the shaft journal 230.
  • the space P2 may be adapted to leading lubricating oil to the space P1 in the cover, in which case the space P3 will be used to lead lubricating oil back to the gear housing.

Abstract

L'invention porte sur un dispositif (299) pour véhicules, destiné à distribuer un lubrifiant d'un bain de lubrifiant (205), incorporé dans un carter d'engrenages (210), à un couvercle tournant (240) puis en retour au bain de lubrifiant (205), un arbre (260) entraîné par une couronne (215) s'étendant entre le carter (210) et le couvercle (240), et le lubrifiant devant être transféré dudit bain (205) aux moyens de distribution (220, 280) par la couronne (215). Les moyens de distribution (220, 280) comprennent un manchon (280) monté autour de l'arbre (260) et qui tourne dans une portée d'arbre (230) d'une roue entraînée (261, 262). Le manchon délimite des espaces (P2, P3) entre l'arbre d'entraînement (260) et la portée d'arbre (230) qui l'entoure, lesquels espaces (P2, P3) participent à la distribution du lubrifiant dudit bain (205) au couvercle (240) et en retour audit bain (205). L'invention porte aussi sur un véhicule à moteur (100; 110) comportant le dispositif (299).
