How does the pump work in a torque converter?
The pump of the torque converter is made up of small fins that make the connection to the flywheel possible. They also serve to pump the transmission fluids to the outside of the mechanism. This creates a vacuum that in turn delivers more fluid to the central part of the device.
Why do you need a torque converter in your car?
For starters, torque converters allow for automatic transmission vehicles, which a majority of people agree are easier and more comfortable to drive. It also allows the car to do a full stop without stalling the engine, which makes driving a more efficient and pleasurable experience.
How can I tell if my torque converter is bad?
Make sure to check first if you have enough high-quality fluid running in your car’s system. Another telltale sign of a faulty torque converter is dirty transmission fluid. If there are black flecks present in the fluid, then you should replace that also. Doing so might just end up saving you a lot of money.
How much torque does a centrifugal pump need?
To overcome pump inertia and static friction, approximately 20% of full load torque is required. As the pump’s speed increases, the required torque gradually declines. For example, at about 15% full load speed the required torque typically is around 5% or 10% full load torque. As shown below, the pump torque-speed curve follows the square law:
What happens when the pump on a torque converter fails?
When the pump inside the torque converter fails, transmission fluid will not feed through the pump inside the converter. This will cause many different torque converter problems, so you should keep an eye out for the following symptoms:
How does a torque converter work in a car?
A torque converter uses power from the engine in an automatic transmission to change gears. Think of it as the clutch in a manual transmission. Each time you move between gears, you have to press down and slowly release the clutch. The blade assembly inside of a torque converter controls the flow of transmission fluid.
Locate your container near the oil dipstick. It typically has a coloured handle, making it easy to spot. Pull up the transmission fluid and check the dipstick. If the liquid seems low, that means you need to top off the transmission. Other signs of transmission slippage are a low fuel economy.
Why is long life of torque converter important?
If long torque converter life is an objective, it is extremely important that the fins of the impeller pump are adequately reinforced against fatigue and the outside housing does not distort under stress.
