They are of similar design, but a fluid coupling simply transmits torque (with some frictional loss), while a torque converter amplifies torque, similar to a reduction gear.
no
yes,i think so.
i don't know actually
It is a fluid coupling using a viscous (thicker type) fluid, similar to the coupling between the drive and driven impeller of an automatic transmission in a car.
Fluid couplings offer several advantages over torque converters, primarily in their simplicity and efficiency. They provide smooth power transmission without the complexity of gear changes, which can lead to less wear and maintenance. Additionally, fluid couplings can transmit torque efficiently at low speeds, making them ideal for applications like industrial machinery. However, they do not provide the same level of torque multiplication as torque converters, which can be a disadvantage in some scenarios.
Breather is provided where the oil tends to give out fumes after getting heated. in a fluid coupling the fluid is not heated upto that temperature hence not required
It does not connect to the head. The torque converter connects directly to the crankshaft of the engine. IA torque converter is a modified form of fluid coupling that is used to transfer rotating power from an internal combustion engine or electric motor, to a rotating driven load. Like a basic fluid coupling, the torque converter normally takes the place of a mechanical clutch. In a torque converter there are at least three rotating elements: the pump, which is mechanically driven by the engine; the turbine, which drives the load; and the stator, which is interposed between the pump and turbine so that it can alter oil flow returning from the turbine to the pump.
resilient plate is used to protect fluid coupling from damages and takes the overload acting on the device ,
You can empty it out and change the fluid if there is nothing wrong with it and the stock stall speed will still work with the engine you will be putting in front of it. It's basically a fluid coupling. Since it's full of fluid and the fluid does most of the work, there is very, VERY little wear inside a converter. The only exception is if you have a lockup torque converter. The clutches inside lockup converters DO wear out and ultimately fail.
The Torque Converter uses the same fluid as the transmission. The transmission has a filter. So, in effect...the answer is "Yes" torque converter fluid is filtered. However, the torque converter has no special fluid of its own.
The lockup solenoid does not control OD shift. The lockup solenoid controls torque convertor lockup. Torque converter lockup isn't a gear at all, but a fuel saving function that kicks in when you are cruising, which is a clutch in the torque converter that locks down and overrides the fluid coupling so you dont loose engine engine torque due to the normal fluid coupling of the torque converter. In effect, it overrides the torque converter completely, and provides a direct drive from the engine to the input shaft of the transmission. TC lockup does occur in OD, but it is a separate function. OD is achieved in the AX4N when the OD band holds the front planetary sun gear stationary. This is done by the OD servo and piston assembly, when fluid is directed there through a valve in the valve body. You could have a problem in any of those areas causing you not to have OD.
