Forklift Transmission Charging Pump
Transmission oil supply pump: provides hydraulic power: provides the necessary hydraulic power to operate the control valve and clutch.
Ration supply of gear oil: ensure that the gear oil in the transmission and differential box is replenished with an appropriate amount.
Cyclic heat dissipation: Send the transmission oil to the cooler for cyclic heat dissipation to prevent oil temperature from being too high
The transmission oil supply pump is usually installed behind the hydraulic torque converter and is driven by the shaft sleeve at the rear end of the torque converter. Its working principle is as follows:
When the engine is running, the shaft sleeve at the rear end of the torque converter housing drives the outer gear and the inner gear to run together.
In the oil absorption chamber, due to the continuous withdrawal of the external gear and the internal gear, the volume increases, forming a local vacuum, and sucking the hydraulic oil from the oil pan.
As the gear rotates, the hydraulic oil between the teeth is brought to the pressure oil chamber and the volume continues to increase, generating vacuum suction, and continuing to suck the hydraulic oil into the pump.
When the wheel teeth enter the end of the meggation, the volume continues to decrease, the oil pressure increases, and finally the oil is pressed out of the oil pump.
