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
A torque tube system is a power transmission and braking technology that involves a stationary housing around the drive shaft, often used in automobiles with a front engine and rear drive.
Some areas of failure on this transmission include leaks in the oil filling tube by removing the cap incorrectly, damage to plastic internals due to fluid over-temperature conditions, leaks in the transmission oil cooler, internal fluid pressure leaks from torn piston diaphragms, worn piston bores for solenoids in aluminum valve body, and the resulting worn clutches and bands.
In an internal combustion engine, a head gasket provides the seal between the engine block and cylinder head(s). Its purpose is to seal the combustion gases within the cylinders and to avoid coolant or engine oil leaking into the cylinders. [1] Leaks in the head gasket can cause poor engine running and/or overheating.
Idle creep, sometimes called idle speed or just creep [citation needed] is the default speed that a vehicle with an automatic transmission will move either forward or in reverse when the change lever is in D for drive or R for reverse and the foot is taken off the brake pedal but the accelerator pedal is not depressed.
Since the late 1940s, the hydrodynamic torque converter has replaced the fluid coupling in automotive applications. In automotive applications, the pump typically is connected to the flywheel of the engine —in fact, the coupling's enclosure may be part of the flywheel proper, and thus is turned by the engine's crankshaft .
Due to vibration, temperature changes, and other factors such as spiral wound gasket stress relaxation, the bolt tension will gradually decrease, resulting in loss of torque, causing a leak. In general longer bolts and smaller diameters of bolt are better at preventing the loss of torque. A long thin bolt is an effective way to prevent torque loss.
Gaps can develop between the apex seal and trochoid housing in light-load operation when imbalances in centrifugal force and gas pressure occur. At low engine-rpm ranges, or under low-load conditions, the gas pressure in the combustion chamber can cause the seal to lift off the surface, resulting in combustion gas leaking into the next chamber.
