2. Torque converter - Wikipedia

   en.wikipedia.org/wiki/Torque_converter

   A torque converter is a device, usually implemented as a type of fluid coupling, that transfers rotating power from a prime mover, like an internal combustion engine, to a rotating driven load. In a vehicle with an automatic transmission, the torque

3. Retarder (mechanical engineering) - Wikipedia

   en.wikipedia.org/wiki/Retarder_(mechanical...

   Exhaust brakes are simpler in operation than an engine brake.Essentially, the exhaust pipe of the vehicle is restricted by a valve.This raises the pressure in the exhaust system, forcing the engine to work harder on the exhaust stroke of its cylinders, so again the engine is acting as an air compressor, with the power required to compress the air being withheld from the exhaust pipe, retarding ...

4. Electromagnetic clutches and brakes - Wikipedia

   en.wikipedia.org/wiki/Electromagnetic_clutches...

   Usually the magnetic field is bolted to the machine frame (or uses a torque arm that can handle the torque of the brake). So when the armature is attracted to the field the stopping torque is transferred into the field housing and into the machine frame decelerating the load. This can happen very fast (.1-3sec).

5. Traction control system - Wikipedia

   It is often implemented with an electronic limited-slip differential, as well as other computerized controls of the engine and transmission. The spinning wheel is slowed with short applications of brakes, diverting more torque to the non-spinning wheel; this is the system adopted by Range Rover in 1993, for example. ABS brake-traction control ...

6. ZF 6HP transmission - Wikipedia

   There are also problems with the valve block and solenoids [citation needed] When this failure starts to occur, shift quality and speed, torque transfer and even loss of ability to engage gears can occur. These problems led Volkswagen Group to extend the warranty on all of their vehicles equipped with this transmission to 100,000 miles or 10 years.

7. Prony brake - Wikipedia

   Prony brake dynamometers at a tractor contest in 1910 Schematic of a Prony brake Actual Prony Brake built for testing 5HP Steam Engine. The Prony brake is a simple device invented by Gaspard de Prony in 1821 to measure the torque produced by an engine. The term "brake horsepower" is one measurement of power derived from this method of measuring ...
