Oil Supply Device

Abstract

An oil supply device for a motor vehicle transmission ( 2 ) with gear wheels provided on shafts, with bearings in which gearwheels and shafts are pivoted, and with synchronization devices ( 10 ), which can be moved into the desired shifting positions by actuation of a shifting lever via selector shafts and shifting forks, wherein a shaft ( 4 ) has an axially extending central borehole ( 6 ) and at least one transverse borehole ( 8 ) for oil supply, has boreholes ( 14 ) in a synchronous element ( 12 ) of the synchronization device ( 10 ) as well as a retaining plate ( 16 ) with a sickle-shaped recess ( 18 ).

1 - 4 . (canceled)  
     
     
         5 . A device for supplying oil to a motor vehicle transmission ( 2 ) having gear wheels disposed on shafts, bearings which rotationally support the gear wheels and the shafts, and synchronization devices ( 10 ) which are displaced into desired shifting positions by actuation of a shifting lever via one or more of selector shafts and shifting forks, the device comprising a shaft ( 4 ) having an axially extending central borehole ( 6 ) and at least one radially extending borehole ( 8 ) for directing an oil supply, a synchronous element ( 12 ) of the synchronization device ( 10 ) having boreholes ( 14 ), a retaining plate ( 16 ) located between the synchronization device ( 10 ) and a bearing ( 28 ), the retaining plate ( 16 ) having a sickle-shaped recess ( 18 ), and the synchronous element ( 12 ) having grooves ( 30 ) in which lugs ( 32 ) of an insert ( 34 ) are braced.  
     
     
         6 . The oil supply device according to  claim 5 , wherein the synchronous element ( 12 ) is axially closed at a first end opposed to a second end adjacent a bearing ( 20 ), with a plate.  
     
     
         7 . The oil supply device according to  claim 5 , wherein the shaft ( 4 ) has at least one radially extending borehole ( 22 ) in a region of a running surface ( 24 ) of the gear wheel ( 26 ).  
     
     
         8 . The oil supply according to  claim 5 , wherein a thrust washer ( 36 ) is located between a first gearwheel ( 26 ) and a second gearwheel ( 38 ), and has grooves ( 40 ).  
     
     
         9 . A device for supplying oil to a motor vehicle transmission ( 2 ), the transmission having a plurality of gear wheels disposed at least one shaft, a plurality of bearings which rotationally support the gear wheels and the at least one shaft, and at least one synchronization device ( 10 ) which is displaced into desired shifting position, by actuating a shifting lever via one or more of selector shafts and shifting forks, the device comprising: 
 a shaft ( 4 ) having an axially extending central borehole ( 6 ) and at least one radial borehole ( 8 ) for directing an oil supply, the at least one radial borehole extending radially between the central borehole and an exterior of the shaft to a running surface ( 24 ) of a first gear wheel ( 26 );    a synchronous element ( 12 ) of the synchronization device ( 10 ) having at least one axially extending boreholes ( 14 ) for directing the oil supply, and a plurality of grooves ( 30 ) in which lugs ( 32 ) of an insert ( 34 ) are braced;    a retaining plate ( 16 ) located between the synchronization device ( 10 ) and a first bearing ( 28 ), the retaining plate ( 16 ) having a sickle-shaped recess ( 18 );    the synchronous element ( 12 ) being axially closed by a plate on a first end opposed to a second end adjacent a bearing ( 20 ); and    a thrust washer ( 36 ) is located between the first gear wheel ( 26 ) and a second gear wheel ( 38 ) and has grooves ( 40 ).
