Which of the four components is responsible for multiplying engine torque?

By directing fluid from the turbine back to the pump impeller, the stator is responsible for the stall speed and torque multiplication of the converter. In addition to those four components, lockup converters add a lockup piston to the mix, which enables the converter to lock up at cruising speed.

Which component in the torque converter allows multiplication of the torque?

the stator
The key to the torque converter’s ability to multiply torque lies in the stator.

What are the four components 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.

Which of these components multiplies the torque from the engine by running it through a number of different gear ratio?

Gear sets will multiply torque, but at a reduced speed. An idler gear allows the drive and driven gears to rotate in the same direction. To find the ratio, divide the driven gear by the drive gear.

How do you multiply torque?

1. Multiply the force acting on the first gear by the first gear’s radius.
2. Divide the second gear’s radius by the first gear’s.
3. Multiply the gear ratio by the input torque that you calculated in the first step: 2 x 1000 = 2,000 newton-meters.

How does torque multiplication occur?

The torque multiplication through the stator occurs when the converter is in ‘stall mode’ and during initial vehicle acceleration. As the vehicle accelerates, the torque multiplication decreases until it reaches a ratio of 1:1 with the crankshaft torque.

How is torque multiplied?

One of the characteristics of a torque converter is that it multiplies torque, by a factor of as much as two to two-and-a-half times or even more, depending on the design. Maximum torque multiplication occurs at rest, as the vehicle just starts moving. As speed increases, the torque multiplication decreases.

What does the torque converter do?

Your vehicle’s torque converter is the same as the clutch of a vehicle with a manual transmission. However, unlike a manual transmission vehicle, it uses fluid to transmit power to the transmission preventing your engine from stalling and allowing the transmission to change.

What are the components of torque?

In other words, torque is the cross product between the distance vector (the distance from the pivot point to the point where force is applied) and the force vector, ‘a’ being the angle between r and F.

Which of the following components can be used to transfer engine crankshaft torque to the torque converter assembly?

The flexplate is positioned between the engine crankshaft and the torque converter. The purpose of the flexplate is to transfer crankshaft rotational force to the shell of the torque converter assembly.

Which of the following torque converter components is attached to the engine flywheel?

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.

Why do we need torque multiplication from the torque convertor?

The multiplication factor is based on the speed difference between the turbine and impeller. At stall speed, the impeller is spinning at engine rpm and the turbine is stopped. This creates the greatest speed difference between the turbine and the impeller and therefore the maximum torque multiplication.
