Advantages
•
Cooler mounting flexibility
•
Convenient chassis location
o
Direct mount on transmission
o
In radiator mounting
•
Not sensitive to vehicle speed
Disadvantages
•
Adds heat load to total motor cooling system
•
Requires coolant connection to radiator
•
Requires installation evaluation & lubrication check
Note: If this option is used, the coolant loop must NOT be in line with the e-motor and controller/inverter
coolant loop. The transmission coolant loop must be separate from the e-motor and MCU coolant
loop.
Note: Eaton OEM part 5586750 oil to water cooler is available in China

Air supply to the transmission
The transmission requires an air supply for shifting. The requirements for the air supply to the transmission are:
•
Operating pressure range at transmission to be within 7.5 bar to 8.3 bar. Minimum is 7 bar to support
High/Low or Low/High gear shifts.
•
High/Low and Low/High gear shifts will not be executed if the pressure is between 3.5 and 7 bar. The
system will maintain the gear that it is in when loss of pressure occurs until it is commanded to the
Neutral gear position.
•
Gear disengagement may occur at pressure ~3.5 bar. Below 7 bar, the system will attempt to maintain
gear engagement by applying the minimum torque required to prevent disengagement until it is
commanded to the Neutral gear position.
•
Flow 300 to 500 dm^3/min at pressure 7 bar.
•
Minimum flow through exhaust 8dm^3/sec.
•
Filter air contamination between 15 and 30 microns.
Note: 6.35mm (1/4”) tube OD push-to-connect fitting is installed on valve. To use 6mm tube, customer must
replace with compatible fitting for proper assembly.
The vehicle manufacturer is responsible for the air supply and the connections to the transmission
