It separates and sets heat emission hole；By the first cooling fin towards radiating shell both ends, the axial gap between adjacent two cooling fin is gradually reduced.
The type of cooling of existing wheel hub motor is directly to have two holes in wheel hub motor upper end, and a hole is that oil inlet is logical
Another channel of road is oil discharge passage, plays the role of cooling motor by the cooling oil path of enclosure, needs the inspection of timing
It is whether clean and sufficient to look into cooling oil.The Comparision of maintaining is cumbersome；In addition, the shell of existing wheel hub motor is generally all

Corresponding, the cooling fin of the first cooling fin both sides is sequentially arranged symmetrically from high to low relative to the first cooling fin of two panels.When wheel hub electricity
In the heat transfer of machine to 2 first cooling fins, most of heat is taken away by air, and heat concentrates on 2 in order to prevent
It around piece cooling fin and prevents from forming vortex on 2 first cooling fins, is unfavorable for heat and distributes, on 2 first cooling fins
Heat emission hole opens up position and should correspond so that the heat inside wheel hub motor can continue to propagate forward, and be not easy to form whirlpool
Stream.
Further, 3 quantity of the cooling fin is 5~10.It can be according to the power and selection of speed of wheel hub motor
