Acceleration was minimal and smoothed in the use of strain accumulator and aid valves Found in between the pump and motor, to avoid the unexpected variations in speed feasible with direct hydraulic coupling. Subsequent variations incorporated fastened swash plate motors and ball pumps.[citation desired]
Signs or symptoms: A recognizable hold off when shifting gears or even the auto not going promptly following shifting.
In a typical CVT, there is an enter pulley that's linked to the engine crankshaft via a torque converter (or clutch pack) and an output pulley that sends energy into the wheels.
