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, ...
Toyota Motor Corporation's A family is a family of automatic FWD/RWD/4WD/AWD transmissions built by Aisin-Warner.They share much in common with Volvo's AW7* and Aisin-Warner's 03-71* transmissions, which are found in Suzukis, Mitsubishis, and other Asian vehicles.
The aluminum die-cast case is 10 % lighter, yet 30 % more rigid, even with two additional gears and a 22 % greater torque capacity the new transmission weighs 95 kg (209 lb) or 10 % more than the previous unit. With new micro-laser technology gear tooth production tolerances have been reduced 50 %.
The torsional deflection of a simple cylinder cannot radiate efficiently acoustic noise, but with particular boundary conditions the stator can radiate acoustic noise under torque ripple excitation. [8] Structure-borne noise can also be generated by torque ripple when rotor shaft line vibrations propagate to the frame [9] and shaft line.
Torsional vibration is a concern in the crankshafts of internal combustion engines because it could break the crankshaft itself; shear-off the flywheel; or cause driven belts, gears and attached components to fail, especially when the frequency of the vibration matches the torsional resonant frequency of the crankshaft.
The basis of the Turboglide's unique abilities was its five-element torque converter.Most automatic transmissions have a three-element torque converter, consisting of an impeller (an engine-driven pump); a turbine that rotates with the flywheel; a transmission-driven turbine that receives the energy of the oil propelled by the impeller, and a stator that redirects the recirculating oil so that ...
Schaeffler torque converter with centrifugal pendulum absorber. A centrifugal pendulum absorber is a type of tuned mass damper. It reduces the amplitude of a torsional vibration in drive trains that use a combustion engine.
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.
