A wheel loader's hydraulic torque converter typically consists of a pump wheel, a first and second turbine group, a guide wheel, a guide wheel seat, a cover wheel, a torque converter casing, and sealing components. The first and second turbine groups are the key components.
The pump wheel is connected to the engine's crankshaft and is responsible for driving the hydraulic fluid inside the torque converter. As the pump wheel rotates, it creates a flow of fluid that is directed towards the first turbine group.
The first turbine group is connected to the pump wheel and is responsible for transferring the energy from the hydraulic fluid to the second turbine group. It consists of multiple blades that are designed to efficiently convert the fluid's energy into rotational motion.
The second turbine group is connected to the first turbine group and is responsible for transmitting the rotational motion to the transmission system of the wheel loader. It also consists of blades that are designed to maximize the torque output.
The guide wheel and guide wheel seat are positioned between the first and second turbine groups to control the flow of fluid and ensure efficient energy transfer. They help direct the fluid towards the second turbine group while minimizing losses.
The cover wheel is located at the outer end of the torque converter and is responsible for housing the pump wheel, first and second turbine groups, and the guide wheel. It provides protection and support to these components.
The torque converter casing encloses the entire torque converter assembly and provides structural integrity. It also helps in maintaining the fluid pressure and prevents leakage.
Sealing components, such as gaskets and O-rings, are used to prevent fluid leakage and maintain the integrity of the torque converter system.
In conclusion, the pump wheel, first and second turbine groups, guide wheel, guide wheel seat, cover wheel, torque converter casing, and sealing components together form the hydraulic torque converter of a wheel loader. The first and second turbine groups play a crucial role in transferring energy and torque from the hydraulic fluid to the transmission system.
