Forklift Gearbox Torque Converter
The hydraulic torque converter consists of a pump wheel, a turbine and a guide wheel. Installed between the engine and the transmission, with hydraulic oil (ATF) as the working medium, it plays the role of transmitting torque, torque change, variable speed and clutch. In addition to the important role of allowing the car to stop completely without stopping the engine, the hydraulic torque converter can also allow the car to obtain greater torque when accelerating from the parking state. The new hydraulic torque converter can increase the engine torque by 2-3 times.
The torque converter is composed of a turbine, a pump wheel, a guide wheel, a locking clutch assembly and a back cover.
(1) The role of the clutch. When the engine is running at idle speed, the torque converter is equivalent to an unjointed clutch between the engine and the gearbox.
(2) Increase the torsion effect. The combination of "high pump wheel speed" + "low turbine speed" is used to increase the torque, thus generating a large starting and driving torque.
(3) Hydraulic coupling. In non-idling or non-starting conditions, it is equivalent to a hydraulic coupler that transmits engine torque to the gearbox.
(4) Locking effect. When the turbine speed rises to the same speed as the pump wheel, the locking clutch is connected, and the torque converter transmits the engine power 1:1 to the gearbox.
