Oil duct connects, and described left shell is provided with the second circulation oil duct, and output axocoel is connected by described second circulation oil duct with collection chamber,
Described middle shell is provided with the 3rd circulation oil duct, and the lubricating oil in described collection chamber is by described 3rd circulation oil duct lubrication output
Axle bearing.
Further, described left shell is provided with the first sealing strip, and described first sealing strip is provided with breach, described breach
Cooperatively forming the first circulation oil duct with middle shell, described second circulation oil duct is located on the first sealing strip.
Further, described middle shell is provided with the second sealing strip, and described 3rd circulation oil duct is located on the second sealing strip.
Further, described second sealing strip is additionally provided with oil scupper.
Further, described left shell is positioned at power shaft intracavity and is provided with reinforcement.
This utility model electric bridge electric machine casing lubricant passage way left shell and fixing formation of middle shell input axocoel, jackshaft
Chamber, collection chamber and trapped fuel chamber, be provided with the first sealing strip on left shell, is provided with the second sealing strip on middle shell, and first seals
Limit and the second sealing strip cooperatively form airtight collection chamber, be provided with breach and cooperatively form first with middle shell on the first sealing strip
Circulation oil duct, connects collection chamber with trapped fuel chamber, is provided with the second circulation oil duct so that it is the profit in collection chamber on the second sealing strip
The bearing of oil lubrication power shaft.The oil circuit of its design is simple, it is simple to safeguard or easy to maintenance.Set on the second sealing strip simultaneously
There is oil scupper, when bridge-operative, collection chamber can be carried out pressure release.

Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figures 1 to 4, the better embodiment of this utility model electric bridge electric machine casing lubricant passage way includes left shell
1 and middle shell 2, left shell 1 and middle shell 2 is fixing forms input axocoel 5, middle axocoel 6, collection chamber 3 and trapped fuel chamber 4.Described
Input axocoel 5 is used for installing power shaft, described middle axocoel 6, is provided with Driven Gear of Final Reduction Gear in described trapped fuel chamber 4.Described trapped fuel
Chamber 4 is connected by the first circulation oil duct with collection chamber 3, and described left shell 1 is provided with the second circulation oil duct, described second recycle oil
Output axocoel is connected by road with collection chamber 3, and described middle shell 2 is provided with the 3rd circulation oil duct, the lubricating oil in described collection chamber 3
By described 3rd circulation oil duct lubrication output shaft bearing.
Specifically, described left shell 1 is provided with the first sealing strip 11, and described first sealing strip 11 is provided with breach 111
With perforation 112, described breach 111 cooperatively forms the first circulation oil duct with middle shell 2, and described perforation 112 is the second circulation oil duct,
Collection chamber 3 is connected by described perforation 112 with input axocoel 5.It is positioned at power shaft chamber 5 on described left shell 1 and is provided with reinforcement 12,
Described reinforcement 12 is for increasing the intensity of power shaft axis hole 13.Described middle shell 2 is provided with the second sealing strip 21, described second close
Edge sealing 21 coordinates fixing formation to input axocoel 5, middle axocoel 6 and trapped fuel chamber 4 with the first sealing strip 11.Described second sealing strip
21 are provided with through hole 211 and oil scupper 212, and described through hole 211 is the 3rd circulation oil duct；Described oil scupper 212 is at electric bridge
The pressure in collection chamber 3 is reduced, to increase the service life during work.
When bridge-operative, the lubricating oil in trapped fuel chamber 4 is stirred by final gear, flows into oil-collecting from the first oil leab
Chamber 3, the lubricating oil in collection chamber 3 flows into input axocoel 5 by the second oil leab, and the lubricating oil in collection chamber 3 is the most logical simultaneously
Cross the 3rd oil leab the bearing of power shaft is lubricated, and collection chamber 3 is reduced pressure by oil scupper 212, prevents pressure
