How a Torque Converter Works
Apr 01, †Ј The housing of the torque converter is bolted to the flywheel of the engine, so it turns at whatever speed the engine is running at. The fins that make up the pump of the torque converter are attached to the housing, so they also turn at the same speed as the engine. The cutaway below shows how everything is connected inside the torque nicefreedatingall.com: Karim Nice. Sep 26, †Ј How does a torque converter work? There are three main parts in a torque converter. 1. Impeller. The first part of the torque converter assembly is called the impeller, also known as the pump. It is filled with fluid and it spins with the engine crankshaft. The faster it spins, the more force is created as the fluid flows through it faster and.
Manual transmission cars use a clutch that disconnects the engine from the transmission. Automatic transmissions use a torque converter. When the engine is idling, such as at a stop light, the amount of torque going through the torque converter is small, but still enough to require some pressure on the brake pedal to stop the car from creeping. When you release the brake and torwue on the gas, the engine speeds up and pumps more fluid into the torque converter, causing more power torque to be transmitted to the wheels.
The first part of the torque converter assembly is called the impelleralso known as the pump. It is filled with fluid and it spins with the engine crankshaft. The faster it spins, the more force is created as the fluid flows through it faster and harder. The impeller forces the fluid into an assembly of blades woros the turbine. The turbine sits opposite the impeller and rotates as how to reset hp printer cartridge chips fluid from the impeller hits its blades.
As the fluid flows through the turbine, it is repeatedly transferred from the outer section to the inner section of the turbine, then returned to the convetter. The stator reverses the fluid and sends it back to the impeller, thereby slowing the fluid. As the transmission fluid returns to the impeller to keep the cycle going is where the torque is created. At this point the fluid is flowing worls a different direction than it was originally as it came out of the impeller.
This is where the stator comes in. The stator is another series of fins located between the two turbines on the transmission shaft. Its blades are angled so that when the transmission fluid flows into them, it reverses direction and gets channeled back to the impeller. The vehicle does not move, but it does not stall. Acceleration occurs when the driver takes his foot off the brake and steps on the gas pedal. The impeller starts rotating faster, and there is a large difference between the impeller and turbine speed.
This creates torque, and the converter produces torque multiplication, which is necessary for acceleration. As the vehicle reaches cruising speed, the turbine rotates at about the same rate as the impeller, and torque buildup stops. At this stage the torque converter is just a fluid coupling. This eliminates power loss and keeps the car moving smoothly. Because the impeller is mounted to the torque converter housing, and the converter is connected to the engine, the impeller gets its power from the engine.
The turbine is connected to the output shaft, which sends power to the transmission. This why you might experience shaking or shuddering when something goes wrong with the torque converter. An accurate Vehicle Courtesy Check by a trained, honest transmission technician will tell you what the problem is and what repairs you need.
It might just be a fluid leak, or something else altogether Ч our transmission inspection and Vehicle Courtesy Check help us find the problems and recommend the how to write a written agreement services.
If your car shakes and shudders, it might mean the lockup clutch is failing or needs adjustment. If your car overheats regularly, it might be a sign the transmission fluid is low. Additionally, low fluid can cause the torque converter to malfunction.
This results in poor acceleration and excessive wear and tear on the transmission. A damaged fin in the torque converter can cause faltering in the transmission as it shifts, or the transmission to totally slip out of gear. This is due to the engine torque not being converted into the hydraulic pressure the transmission needs to shift gears.
Slipping can also wprks caused by too little or too much fluid in the transmission. A malfunctioning or failing torque converter will cause the transmission worrks longer to engage with the engine.
This results in high stall speeds. Any weird sounds such as clicking, revving, clunking, or whining indicate possible problems with the torque converter Ч or the transmission. Even a poorly built transmission will suffer from poor maintenance.
Things such as wrong fluid types or incorrect amounts of fluid can cause a lot of damage to a transmission. Incorrect fluid levels usually result from a poor or nonexistent maintenance schedule, as well as ignorance of what is required to effectively maintain a car.
If you check the fluid yourself, be aware of not only the levels, but the colors. Neglecting to be aware of the simple things that can help or hinder your transmission will speed its demise.

Automatic Transmission Torque Converters
Jan 02, †Ј nicefreedatingall.com torque converter is often seen as the most complicated part in vehicles of today. It is, however, a very impo. Jul 07, †Ј How Does a Torque Converter Work? To understand how a torque converter works, start by picturing two fans sitting face-to-face. One fan, the impeller, is powered because itТs connected to the engine. The other fan, the turbine, is not plugged in because itТs connected to the transmission. The torque converter is placed between the internal combustion engine and the gearbox. An automatic transmission, inside its case, contains three main parts: the torque converter, the epicyclic (planetary) gearbox and the electro-hydraulic control module.
Imagine you have two fans facing each other. Turn one fan on, and it will blow air over the blades of the second fan, causing it to spin. But if you hold the second fan still, the first fan will keep right on spinning. The other fan, the turbine, is connected to the transmission input shaft. Unless the transmission is in neutral or park, any motion of the turbine will move the vehicle. Instead of using air, the torque converter uses a liquid medium, which cannot be compressed Ч oil, otherwise known as transmission fluid.
Automatic transmission cars use a torque converter. This article will discuss why automatic transmission cars need a torque converter and how a torque converter works. The torque converter in an automatic transmission serves the same purpose as the clutch in a manual transmission.
The engine needs to be connected to the rear wheels so the vehicle will move, and disconnected so the engine can continue to run when the vehicle is stopped. One way to do this is to use a device that physically connects and disconnects the engine and the transmission Ч a clutch. Another method is to use some type of fluid coupling, such as a torque converter, which is located between the engine and the transmission.
There are three components inside the very strong housing of the torque converter which work together to transmit power to the transmission:. The pump inside a torque converter is a type of centrifugal pump. As it spins, fluid is flung to the outside, much as the spin cycle of a washing machine flings water and clothes to the outside of the wash tub.
As fluid is flung to the outside, a vacuum is created that draws more fluid in at the center. The fluid then enters the blades of the turbine , which is connected to the transmission the spline in the middle is where it connects to the transmission. The turbine causes the transmission to spin, which basically moves your car. The blades of the turbine are curved so that the fluid, which enters the turbine from the outside, has to change direction before it exits the center of the turbine.
It is this directional change that causes the turbine to spin. As the turbine causes the fluid to change direction, the fluid causes the turbine to spin. The fluid exits the turbine at the center, moving in a different direction than when it entered. The fluid exits the turbine moving opposite the direction that the pump and engine are turning. If the fluid were allowed to hit the pump, it would slow the engine down, wasting power.
This is why a torque converter has a stator. 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. In brief, the torque converter is a type of fluid coupling, which allows the engine to spin somewhat independently of the transmission.
It is responsible for pressurizing automatic transmission fluid, a pressurization that supplies the force necessary to shift transmission gears. A worn or dysfunctional torque converter can prevent transmission fluid from being properly pressurized, which in turn negatively impacts transmission gear function and operation.
A systematic checkup by a professional is the best way to isolate the cause of the operating problems and recommend the most effective solution. Want to know more? Visite one of our locations! The evolution of transmissions has made these machines and systems increasingly complex.
When transmission repairs are required, determining the cause and cure for what ails can be tricky. Just as you have other parts of your car serviced, your transmission needs maintenance to ensure a long life and avoid transmission problems.
