Several factors leading to high oil temperature of loader torque converter
2.1 Insufficient system oil intake pressure
According to the heat dissipation principle of the torque converter transmission system, the variable speed pump absorbs working oil from the transmission oil pan through the pressure regulating valve, all the way into the torque converter, after cooling by the radiator back to the oil pan; The other way into the transmission. If the system oil intake pressure is insufficient, the working oil pressure into the torque converter is too small, so that the oil intake is insufficient, the oil into the cooler is too little, so that the oil in the system can not be fully cooled, the oil temperature rises quickly and leads to the transmission temperature is too high. The main reasons for the insufficient oil intake pressure of the system are as follows:
(1) Improper system pressure. Pressure regulating valve is an important part of hydraulic transmission system. It controls the pressure of working oil entering the system. If the pressure regulating valve spool wear leakage or torque converter pressure valve failure, stuck, can not play the regulating role, will cause the torque converter oil supply shortage, pressure reduction.
(2) The wear of the variable speed pump causes the gap between the gear and the end cover to become larger, and the leakage seriously causes the shortage of oil supply; If the system pressure is too low, the amount of oil entering the torque converter is insufficient; If the variable speed pump inlet pipe leakage or oil pan oil level is too low, resulting in the pump suction air, will also cause its insufficient oil supply.
(3) Due to the excessive wear of the hydraulic piston seals in the transmission, the pressure of the hydraulic system drops, the clutch slides, and the oil temperature rises.
