전동 휠 모터 냉각 시스템은 냉각 및 윤활을 위하여 유압 유체를 사용하는 제 1 및 제 2 전동 휠 모터들 및 기어 감속기들을 포함한다. 각각의 전동 휠 모터 하우징들은 유압 유체 레저버로 유압 유체를 회수하기 위한 섬프 및 배유 펌프를 포함한다. 유압 유체 레저버와 상호 연결되는 멀리 떨어져 위치되는 제 1 및 제 2 배유 펌프들은 유압 모터들보다 높은 유체 유동률을 갖고 제 1 및 제 2 전동 휠 모터 하우징들로부터 오일이 제거되는 것을 보장하며 따라서 모터들 또는 기어들의 어떠한 교반 손실도 제거한다.
An electric wheel motor cooling system includes first and second electric wheel motors (104M, 105M) and gear reducers which use hydraulic fluid for cooling and lubrication. Each of the electric wheel motor housings (104, 105) includes a sump (104S, 105S) and a scavenge pump (204, 205) for return of hydraulic fluid to the hydraulic fluid reservoir (210). A remotely located hydraulic pump (201) interconnected with the hydraulic fluid reservoir supplies and powers first and second locally located hydraulic motors (202, 203) which supply the electric motors and gears with an equal flow of lubricating and cooling oil. The first and second hydraulic motors, in turn, drive a common output shaft which, in turn, drives first and second scavenge pumps. The first and second scavenge pumps have a higher fluid flow rate than the hydraulic motors ensuring that oil is removed from the first and second electric wheel motor housings thus eliminating any churning losses of the motors or gears.
