Title:
油水二重冷却の電気駆動アセンブリ及び新エネルギー自動車
Document Type and Number:
Japanese Patent JP7366245
Kind Code:
B2
Abstract:
An electric drive assembly with oil/water dual cooling and a new energy vehicle are disclosed, which solve the heat dissipation problem when the gearbox of the new energy vehicle operates at high speed constantly. The electric drive assembly comprises a motor module, a gearbox module, a water cooling module and an oil cooling module. The oil cooling module in the present disclosure has three oil cooling passages, and can introduce the lubricating oil in the gearbox into the front and rear windings of the motor, thereby improving the cooling performance of the motor, eliminating the need for a motor shaft (22) oil seal, reducing the cost of the drive assembly and improving the transmission efficiency. The water cooling module in the present disclosure cools the motor housing through the motor water jacket (1), and cools the lubricating oil in the gearbox housing (6) through the heat sink (13) at the bottom of the gearbox, thereby solving the heat dissipation problem when the gearbox of the new energy vehicle operates at high speed constantly, and thus improving the service life and reliability of the gear and bearing.
