A wind-cooled hub motor drive assembly

Abstract

The utility model discloses a kind of air-cooled hub motor drive assembly, including wheel rim;The middle part of wheel rim is provided with driving motor;Front end axial flow fan is installed between driving motor and wheel rim;The utility model is rotated by wheel rim and drives front end axial flow fan synchronous rotation, so that front end axial flow fan can continuously discharge hot air in motor casing cooling air duct, and driving motor is preliminarily cooled down.Meanwhile, driving motor itself uses aluminium alloy material, this material has good thermal conductivity, can quickly conduct heat generated in motor interior, plus the heat dissipation fin of outer wall, greatly increase the heat dissipation area, so that heat can be more efficiently dissipated to surrounding environment, realized the function of natural heat dissipation.The synergistic effect of these two heat dissipation modes effectively reduces the temperature of driving motor when it is in normal operation, reduces the performance decline and damage risk caused by overheating.
