Dana torque converter How do you choose?
It is typically located between the engine’s flexible coupling and the transmission. In a manual transmission, the equivalent component is the mechanical clutch. The torque converter performs functions such as torque multiplication and lock-up. When the torque converter is in operation, it tends to generate heat. So, Dana torque converter How do you choose?
Dana torque converter How do you choose?
1. When selecting a hydraulic torque converter for a loader, first check the transmission fluid level, using any leakage from the fluid-level switch on the right side of the transmission as your reference. Next, engage the parking brake to bring the loader to a stop, install a three‑way fitting over the torque converter’s temperature‑check port, and connect a thermometer and an oil‑pressure gauge. This is the procedure for choosing a hydraulic torque converter for a loader.
2. The efficiency of the hydraulic torque converter directly affects the operating efficiency of the loader, and it is influenced by a variety of factors. The installation positions of the pump impeller, stator, and turbine must comply with specifications; the smaller the clearance, the higher the efficiency. However, no matter how high the product quality, all components will eventually wear out or fail.
3. Check the transmission fluid level, using leakage from the fluid-level switch on the right side of the transmission as the reference. Then, operate the parking brake lever to bring the loader to a stop. Install the three-way fitting onto the torque converter’s temperature‑check port, and connect the thermometer and oil pressure gauge.
4. To check the clutch hydraulic pressure, first remove the blockage from the hydraulic control valve’s pressure‑regulating valve, install a pressure gauge, and mount a thermometer at the torque converter oil‑temperature measurement point. After engaging the mechanical brake, run the diesel engine at 1,000 rpm. When the oil temperature reaches 80–90°C, shift the transmission selector lever into high gear and verify that the pressure gauge reading falls within the normal range of 1.078–1.470 MPa.
Dana torque converter What is the difference between a hydraulic coupling and a torque converter?
1. Different energy mechanisms: In a torque converter, the input energy is converted into the kinetic energy and pressure head of the working fluid via centrifugal force, enabling the turbine to perform work. In a fluid coupling, the energy is directly transmitted from the power source.
2. Different applications: Torque converters are widely used as transmission devices between various power machines and working machinery. Hydraulic couplings can be employed in metallurgical equipment, mining machinery, electrical equipment, chemical processing, and a variety of construction machinery.
3. Different operating principles: When the engine is running, the torque converter drives both the converter housing and the pump impeller to rotate together. Under the action of centrifugal force, the hydraulic oil in the pump impeller is thrown from the outer edge of the impeller blades toward the turbine, flows along the turbine blades into the stator, and then returns via the stator blades to the inner edge of the pump impeller blades, forming a circulating fluid flow. A fluid coupling transmits torque by means of changes in angular momentum resulting from the interaction between the fluid and the blades of the pump and turbine.
