Problems solved by technology

[0007] A lubrication system 2 with such an expensive bevel gear 50 has the disadvantage that the vehicle transmission 60 must be extended by more than half the length of the transmission to ensure that the lubrication system
This means higher production and cost expenditures and, moreover, a greater space requirement which is often not available in the engine compartment of a motor vehicle

Embodiment Construction

[0025] figure 1 A partially cutaway perspective view of a vehicle transmission 3 with a lubrication system 1 according to an embodiment of the invention is shown schematically. For the vehicle transmission 3 only the outline of the transmission housing 47 is shown as well as a plurality of lubricant guide elements 40 for conveying lubricant from the lower lubricant collection volume 49 via lubricant guide channels 51 to the upper lubricant collection. flow volume 53 in. Starting from the upper lubricant collection volume 53 , the various transmission shafts and transmission gears are supplied with lubricant by means of the lubricant's gravity and flow velocity.

[0026] The outline of a transmission housing flange 67 is shown for the transmission housing 47 , which can engage with a corresponding clutch flange. The ring gear 50 with the smaller outer diameter is immersed in the lower lubricant collecting volume 49 and conveys lubricant from the lower lubricant collecting vo...

Abstract

The invention relates to a lubricating system (1) used in automobile transmission (3). The automobile transmission is provided with shaft bearings (4 to 9); gear hub bearings (10 to 15) of intermeshed change-speed gear pairs (29 to 34), anti-torsion axially-movable supporting structures for tooth rings (16 to 27) and synchronous clutch elements (35, 36, 37). The lubricant is kept in a loop (38) supported by a gravity and lubricant guiding member (40). a first, a second and a third lubricant groove (44, 45, 46) each provided with a droplet hole (39) are disposed for a first, a second and a third lubrication region (41, 42, 43) respectively; the droplet holes are arranged on the lubrication regions (41, 42, 43) respectively under the lubricant grooves. a disc gear (50) is inserted into a lubricant collection volume (49); and a lubricant guiding channel (51) is extended from the circumference (48) of the disc gear (50) up to a lubricant collection volume (53).

Description

technical field [0001] The invention relates to a lubrication system for a motor vehicle transmission comprising a shaft bearing, a gear hub bearing of an intermeshing transmission gear pair and a torsion-resistant, axially displaceable support structure for a ring gear and a synchronizing clutch element. Lubricant is maintained in a circuit supported by gravity and lubricant guide members. Background technique [0002] Such a lubrication system for a motor vehicle transmission is known from publication US 7,513,172 B2, which comprises a transmission housing in which a shaft is arranged, wherein a rotating part arranged in an end section of the housing serves to ensure a lubricating oil circuit. The rotating part is designed in such a way that it lifts the lubricating oil in order to deliver the lubricating oil into the region of the end section remote from the housing interior. For this purpose, an oil groove is arranged in the transmission housing along the axial directio...
