In above-mentioned oil sealing dustproof cover, the perforative mounting hole of axis is arranged in center in the dust cover body.Peace
Dress hole can be passed through with power supply machine, so that motor installation is stablized.
In above-mentioned oil sealing dustproof cover, the dust cover body is made of nitrile rubber or silicon rubber.The material has
Enough structural strengths and elasticity can preferably form rock-steady structure on mounting structure.
A kind of wheel hub electric motor of electric vehicle, the end cap passed through including motor shaft and power supply arbor, which is characterized in that the motor
Oil sealing dustproof cover as described in the above technical scheme is installed on axis, the flange part of annular, the oil sealing are set on the end cap
Dustproof cover is located in flange part, and blocking portion and dustproof lip are clearance fit with flange part inner wall.Using the structure of flange part,
Stablize convenient for motor shaft and oil sealing dustproof cover and install, can also be sealed convenient for being formed to cover internal.
In above-mentioned wheel hub electric motor of electric vehicle, it is provided on the flange part and the consistent contraposition of blocking portion outer profile
Face.It is consistent with blocking portion outer profile structure to plane, it can allow between dustproof cover and flange part form more uniform row in this way
Aquaporin is convenient for silt steady flow, avoids the occurrence of blocking.
In above-mentioned wheel hub electric motor of electric vehicle, the flange part outer wall is equipped with the water dumping slot of at least one annular.Water dumping
The structure of slot can allow hub motor to be less prone to the residual of water flow during the work time.
Compared with prior art, the utility model has the advantage that
1, between oil sealing dustproof cover and flange part formed bending structure channel, and then can effectively stop extraneous silt into
Enter to inside motor cavity.
2, additional to add dust discharging grooves and silt effectively be stopped, while the silt of entrance can also be arranged
Out, this structure can effectively keep the cleannes of internal dustproof lip itself, and then guarantee service life.
