The gear ratio also determines the transmitted torque. The torque ratio TR AB of the gear train is defined as the ratio of its output torque to its input torque. Using the principle of virtual work, the gear train's torque ratio is equal to the gear ratio, or speed ratio, of the gear
In the fast reverse gear R2, this part of the Ravigneaux gearset is directly connected to the input (turbine) side. To reduce the shaft speed for an appropriate reverse gear R1, the input (turbine) is put through gearset 1 first. This reduction corresponds to the ratio of the 3rd gear.
One standard option for the Brompton folding bicycle is to use a 3-speed hub gear (roughly a 30% difference between gear ratios) in combination with a 2-speed derailleur gear (roughly a 15% difference) to give 6 distinct gear ratios; this is an example of half-step gearing. Some Brompton suppliers offer a 2-speed chainring 'Mountain Drive' as ...
A transmission (also called a gearbox) is a mechanical device which uses a gear set—two or more gears working together—to change the speed, direction of rotation, or torque multiplication/reduction in a machine. [1] [2] Transmissions can have a single fixed-gear ratio, multiple distinct gear ratios, or continuously variable ratios. Variable ...
Crawl ratio is a term used in the automotive world to describe the highest gear ratio that a vehicle is capable of. Note that gear ratio, also known as speed ratio, of a gear train is defined as the ratio of the angular velocity of the input gear to the angular velocity of the output gear, and thus a higher gear ratio implies a larger speed reduction, i.e. the input speed is reduced more at ...
There is therefore one specific gear ratio at which the car can achieve its maximum speed: the one that matches that engine speed with that travel speed. [1] At travel speeds below this maximum, there is a range of gear ratios that can match engine power to air resistance, and the most fuel efficient is the one that results in the lowest engine ...
The marketing name for the transmission is the "Direct Shift – 8AT 8-speed automatic transmission" [3] [4] Unlike the UB 80 transmission, which was developed for Toyota by Aisin AW, the UA 80 was developed in a joint venture between Toyota and Aisin AW. Due to global application, development was done in a global fashion involving engineering ...
The ZF S6-650 is a 6-speed manual transmission manufactured by ZF Friedrichshafen AG. It is designed for longitudinal engine applications, and is rated to handle up to 705 newton-metres (520 lbf⋅ft) of torque. General Motors used the S6 as RPO ML6. Gear ratios:
