Torque converter components (1) Torque converter housing (2) Impeller (3) Pump drive gear (4) Inlet port (5) Output shaft (6) Outlet port (7) Carrier (8) Stator (9) TurbineThe torque converter connects the engine to the planetary transmission through the main drive shaft. The connection between the engine and the transmission is a hydraulic connection. There is no direct mechanical connection between the engine and the transmission.The torque converter uses oil to multiply the torque to the transmission. When the machine works against a low load, the torque multiplication is low. When the machine works against a high load, the torque multiplication is higher. A higher torque can then be sent to the transmission during high load conditions. During no load conditions, the torque converter cannot multiply the torque from the engine.The components of the torque converter are the housing (1), impeller (2), turbine (9), and stator (8) .Housing (1) is connected to the engine flywheel by splines. Impeller (2) and pump drive gear (3) are connected to housing (1). Turbine (9) is connected to output shaft (5). Stator (8) is connected to carrier (7). The stator cannot turn.
