The Kawasaki KR250 was a racing motorcycle built by Kawasaki from 1975 to 1982 for the 250 cc class of Grand Prix motorcycle racing.It was powered by a two-stroke "tandem twin" engine [1] [2] The motorcycle won four world championships, in 1978 and 1979 with Kork Ballington and in 1980 and 1981 with Anton Mang.
Chains are often narrower than belts, and this can make it easier to shift them to larger or smaller gears in order to vary the gear ratio. Multi-speed bicycles with derailleurs make use of this. Also, the more positive meshing of a chain can make it easier to build gears that can increase or shrink in diameter, again altering the gear ratio.
The transmission debuted on the E 350 BlueTEC in 2013, [1] and successively replaced both the 7-speed 7G-Tronic (PLUS) transmission and the 5-speed 5G-Tronic transmission. It includes versions for a maximum input torque of 1,000 N⋅m (738 lb⋅ft). [2] After the 5G- and 7G-Tronic, this is the 3rd generation of modern automatic transmissions.
Mercedes-AMG developed the 7-speed MCT "Multi Clutch Technology" planetary automatic transmission. The MCT transmission is essentially the 7G-Tronic automatic transmission without a torque converter. Instead of a torque converter, it uses a compact wet startup clutch to launch the car from a stop and also supports computer-controlled double ...
1950–1973 Powerglide — 2-speed Chevrolet (also used by Pontiac, Holden, Vauxhall and Opel). 1953-1955 Twin Turbine Dynaflow : the 1st redesign w/ 2 turbines & single stator. 1956-1957 Twin Turbine 2 Dynaflow : the 2nd redesign w/ 2 turbines & variable-pitch stator.
Even the latest 4-speed transmissions are not Simpson; they have only two planetary sets, while a Simpson transmission needs three planetary sets to get four speeds, the third planetary being an integrated overdrive. Nevertheless, it is still possible to find new automatic transmissions based on the Simpson gearset.
Driving with chains reduces fuel efficiency, and can reduce the allowable speed of the automobile to approximately 50 km/h (30 mph), but increase traction and braking on snowy or icy surfaces. Some regions require chains to be used under some weather conditions, but other areas prohibit the use of chains, as they can damage road surfaces.
Blue Star multiple working equipment on a Class 40 locomotive A Class 73 and a Class 33 locomotive being coupled for multiple working. On the rail network in Great Britain, multiple working is where two or more traction units (locomotives, diesel multiple units or electric multiple units) are coupled together in such a way that they are all under the control of one driver (multiple-unit train ...
