The DC/AC inverter (integrated with the motor controller) reverses the DC bus
power supply into three-phase AC power supply for fast start and variable
speed operation of the oil pump motor.
» In order to ensure the smooth operation and long service life of the hydraulic
steering pump, only mineral hydraulic oil can be used.
» Check whether the oil level is proper when refueling.
» After connecting the motor circuit, check whether the rotation direction of the
motor is correct (pulse current with a maximum of 1~2 seconds) by running for
a short time. If the rotation direction is wrong, stop the machine immediately
and correct the rotation direction by adjusting any two phase lines in the three-
phase input, otherwise the motor will be damaged.
» Regularly check the steering oil level in the power steering system.
» After a few hours of initial use, check whether the oil return filter screen is
smooth, and check the pollution level of hydraulic oil.
» Regularly clean the inside of the oil tank, and generally replace the hydraulic
oil after 600~800 hours.
» In heavy load or harsh working environment, check and replace hydraulic oil,
and regularly check the circuit connection of motor, solenoid valve and other
electronic accessories.
» The operating temperature range of hydraulic oil is 5~176 ℉ (- 15~80 ℃ ).
• When it is not powered on under the high voltage, the power steering system
does not work. At this time, it requires a relatively large force to operate the
steering wheel. When towing the vehicle, pay special attention not to power
off the high-pressure system during driving (if the power steering system is
normal).
• When towing, do not turn the steering wheel frequently. Otherwise, the
power steering pump may fail due to lack of lubrication.
· Electric vehicle powertrain
The battery electric vehicle power system is powered by the power battery
assembly, and the driving motor and AMT system output the driving force to
the wheel to drive the vehicle. This vehicle uses the battery electric AMT system.
The shift process is automatically controlled by the electronic control system,
which can significantly reduce the driver's labor intensity and significantly
