  2. Gear train - Wikipedia

    en.wikipedia.org/wiki/Gear_train

    For the wide-ratio transmission, the first gear ratio is 4:1 or 4, and in second gear it is 2:1 or 2, so the progression is equal to ⁠ 4 / 2 ⁠ = 2 (or 200%). For the close-ratio transmission, first gear has a 4:1 ratio or 4, and second gear has a ratio of 3:1 or 3, so the progression between gears is ⁠ 4 / 3 ⁠, or 133%. Since 133% is ...

  3. Bicycle gearing - Wikipedia

    en.wikipedia.org/wiki/Bicycle_gearing

    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 ...

  4. Toyota U transmission - Wikipedia

    en.wikipedia.org/wiki/Toyota_U_transmission

    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 ...

  5. Continuously variable transmission - Wikipedia

    en.wikipedia.org/wiki/Continuously_variable...

    A continuously variable transmission (CVT) is an automated transmission that can change through a continuous range of gear ratios.This contrasts with other transmissions that provide a limited number of gear ratios in fixed steps.

  6. Transmission (mechanical device) - Wikipedia

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

    A continuously variable transmission (CVT) can change seamlessly through a continuous range of gear ratios. This contrasts with other transmissions that provide a limited number of gear ratios in fixed steps. The flexibility of a CVT with suitable control may allow the engine to operate at a constant RPM while the vehicle moves at varying speeds.

  7. Close-ratio transmission - Wikipedia

    en.wikipedia.org/wiki/Close-ratio_transmission

    The designation of wide versus close ratio affected the lowest gear ratio; [7] for example, the four-speed Muncie transmissions offered in General Motors performance vehicles included the M20 "wide ratio" transmission, which had a first gear ratio of 2.52 or 2.56:1, while the M21 and M22 "close ratio" transmissions had a first gear ratio of 2. ...

  8. Crawl ratio - Wikipedia

    en.wikipedia.org/wiki/Crawl_ratio

    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 ...

  9. List of Subaru transmissions - Wikipedia

    en.wikipedia.org/wiki/List_of_Subaru_transmissions

    After its introduction in 1984, the Justy was also available with 4WD and thus a different gearbox. The gear ratios for this gearbox were altered slightly. In 1994 the normal/FWD gearbox was dropped; one could only get a 4WD gearbox by then. Gear ratios: 1st 3.071 2nd 1.695 3rd 1.137 4th .771 5th .631, Rev 3.461 Final 5.200
