A drive axle assembly has at least one axle arm portion extending from a differential housing to a shoulder structure that is unitary with the outboard end of the axle arm portion. The shoulder structure houses a first bevel bear and a second bevel gear. Openings adjacent the bevel gears are selectively closed with covers.
1. A drive axle assembly, comprising:
at least one axle arm portion extending from a differential housing to a shoulder structure that is unitary with an outboard end of said axle arm portion;
a substantially horizontal drive shaft located within said at least one axle arm portion connected at an inboard end to a differential in said differential housing and having a first bevel gear on an outboard end; and
a non-horizontal driven shaft mounted for rotation within said shoulder structure, said driven shaft having a second bevel gear meshed in driving engagement with said first bevel gear on said drive shaft;
wherein said shoulder structure, directly above said second bevel gear consists of, in order, a bearing, a snap ring, and a selectively closable opening solely closed with a cover with two parallel and planar inner and outer surfaces for access thereto.
2. The assembly of claim 1 , further comprising a second selectively closeably opening is axially aligned with said substantially horizontal drive shaft located outboard from said second bevel gear and substantially perpendicular to said drive shaft.
3. The assembly of claim 1 , wherein said selectively closable opening is oriented substantially perpendicular to said driven shaft.
4. The assembly of claim 1 , wherein said second bevel gear is meshed with an upper portion of said first bevel gear.
5. The assembly of claim 1 , wherein said cover is a stamped metallic press-fit cover within said selectively closable opening.
6. A drive axle assembly, comprising:
at least one axle arm portion extending from a differential housing to a shoulder structure that is unitary with an outboard end of said axle arm portion;
a substantially horizontal drive shaft located within said at least one axle arm portion connected at an inboard end to a differential in said differential housing and having a first bevel gear on an outboard end; and
a non-horizontal driven shaft mounted for rotation within said shoulder structure, said driven shaft having a second bevel gear meshed in driving engagement with said first bevel gear on said drive shaft, wherein said first bevel gear is disposed above said second bevel gear;
wherein said shoulder structure is provided with an upper selectively closable opening about both said meshed first and second bevel gears, said upper selectively closeable opening located entirely axially outboard of said first bevel gear and solely closed with a cover with two parallel and planar inner and outer surfaces for access thereto.
7. The assembly of claim 6 , wherein said first bevel gear is meshed with an upper portion of said second bevel gear.
8. The assembly of claim 6 , wherein said selectively closeable cover is a stamped metallic press-fit cover within said selectively closeable opening.
