What are the impeller turbine and stator elements of?
Torque converters are comprised of five main components: the impeller, the turbine, the stator, a clutch, and the fluid. The stator is what makes a torque converter a torque converter; without the stator, it’s just the fluid coupling. The impeller is a piece with tilted blades that look somewhat like a fan.
What does the impeller do in a torque converter?
The torque converter casing connects to the flywheel, spinning at the same rate as the crankshaft, within the housing of the turbine. The impeller or centrifugal pump effectively flings the transmission fluid into the fins of the turbine that in turn spins or transmits the torque into the transmission.
What does the stator do to the oil as it leaves the turbine?
The job of the stator is to correct flow direction of fluid before reaching the impeller. As fluid exits the turbine it is turning the opposite direction of the impeller.
Which is better torque converter or CVT?
Torque converter transmissions offer big torque at low revs, but are generally less efficient than single and dual-clutch transmissions. CVTs offer nearly an infinite number of gear ratios, meaning your engine is always working at peak efficiency, regardless of speed.
What are the 4 parts of a torque converter?
Here are the four primary components worth looking at in industrial torque converter repair.
- Pump. One of the first components to investigate during industrial torque converter repair is the unit’s pump.
- Turbine.
- Stator.
- Transmission Fluid.
What is the stator connected to torque converter?
The stator resides in the very center of the torque converter. Its job is to redirect the fluid returning from the turbine before it hits the pump again. This dramatically increases the efficiency of the torque converter.
What is a stator and what does it do?
The stator is the coil of wire housed inside the engine case. A magnet on a shaft spins within the stator, creating alternating current (AC). That current travels along fairly heavy gauge wire through the case and into the rectifier/regulator which converts it to DC power, and at a consistent output.
Is CVT good for hills?
The L mode in CVT stands for “low gear” mode. In this mode, the transmission does not upshift by itself. Instead, it keeps running at a lower speed ratio to provide more power and torque when driving uphill. This balance makes CVT ideal for driving in the hills.
Which is better clutch or torque converter?
As torque converters handle low torque ranges more easily, they’re most commonly used on off-road go-karts. They perform better at lower speeds and are ideal for stop-and-go situations. Clutches on the other hand are snappier and perform better at high speeds.
How does a stator work in a torque converter?
The stator sends the fluid returning from the turbine to the pump. The stator resides in the very center of the torque converter. Its job is to redirect the fluid returning from the turbine before it hits the pump again. This dramatically increases the efficiency of the torque converter.
Is the stator attached to the turbine or impeller?
The stator is not attached to either the turbine or the impeller – it freewheels, but only in the same direction as the other parts of the converter (a one-way clutch ensures that it can only spin in one direction). When the impeller spins, the moving oil pushes against the fins of the stator.
Where is the stator on a torque converter?
The stator is a small finned wheel that sits between the impeller and the turbine. The stator is not attached to either the turbine or the impeller – it freewheels, but only in the same direction as the other parts of the converter (a one-way clutch ensures that it can only spin in one direction).
Why does oil flow back to the impeller when the turbine spins?
When the impeller spins, the moving oil pushes against the fins of the stator. The one-way clutch keeps the stator still, and the fins redirect the oil back to the impeller. As the turbine speeds up, oil begins to flow back to the impeller on its own (a combination of the turbine’s design and centrifugal force).
How does the impeller work in a torque converter?
The output shaft spins independent of the housing, as the housing and shaft typically rotate at different speeds. The impeller, also called the pump, is responsible for transferring the energy from the engine into the transmission oil, which the torque converter is completely full of.
