It is integrally formed.
Flange part on the end cap of this wheel hub electric motor of electric vehicle is corresponding with thread head of the prior art, is different from existing skill
Flange part on flywheel and end cap is designed as integral structure by art, this end cap by way of casting or die casting so that end cap
The internal diameter design of the seal mounting hole in flange part is not influenceed by the design thickness of thread head in the prior art, so that oil sealing
Hole internal diameter can do increase design, with the bigger oil sealing of installation dimension specification, and then can improve the sealing property of motor.
In the end cap of above-mentioned wheel hub electric motor of electric vehicle, the internal diameter of the seal mounting hole is 30mm~50mm.Existing
Have in technology, limited by end cap thread head, the oil sealing external diameter of the maximum specification that can be selected is 28mm, and more than the application passes through
Design, can select the larger oil sealing of outside dimension, and such as external diameter is the oil sealing of 35mm, 40mm, 45mm, so as to improve same specification
The sealing property of lower motor shaft.
In the end cap of above-mentioned wheel hub electric motor of electric vehicle, flywheel fluted disc shape in a ring, the outer rim of the flywheel is equal
Some sprockets are furnished with, the quantity of the sprocket is 11~20.Preferably, the quantity of sprocket can select 16.
In the end cap of above-mentioned wheel hub electric motor of electric vehicle, the inner face of the flange part has bearing mounting hole.Pass through
Bearing is installed in bearing mounting hole and realizes that end cap is connected with the rotation of motor shaft.
A kind of wheel hub electric motor of electric vehicle, including motor shaft and the oil sealing being set on motor shaft, it is characterised in that also include
Above-mentioned end cap, the motor shaft is arranged in seal mounting hole through the flange part and the oil sealing on above-mentioned end cap.Above-mentioned
In wheel hub motor, the end cap at least side of its both sides is using the end cap in above-mentioned technical proposal.
Compared with prior art, the end cap of this wheel hub electric motor of electric vehicle has advantages below：This end cap uses one with flywheel
Body formed design so that seal mounting hole internal diameter can do increasing design such that it is able to accommodate the oil sealing of bigger specification, enter
And it is improved the sealing property of electric vehicle motor；Meanwhile, electric motor car manufacture and assembling procedure are reduced, save and be produced into
This, improves production efficiency.
