Mercedes-Benz 4G-Tronic Transmission
The Mercedes-Benz 4G-Tronic transmission was produced from 1979 to 1996 in W4A 028, W4A 040 (both type 722.3), W4A 020 (type 722.4), and W5A 030 (type 722.5) variants. Abstract The 4G-Tronic transmission is a hydraulically operated four speed automatic without lock-up that replaced the similarly designed W3A 040, W3B 050, and W4B 025 family of automatic transmissions with the introduction of the W126 S-Class in 1979. In some models it is calibrated to move off in second gear to reduce "creeping" and provide a smoother ride, selecting 1st only if the selector is in "2" or in case of abrupt acceleration. Other calibrations have the transmission rest in 2nd gear and kick down to 1st as soon as the accelerator is touched but before the throttle is opened. In some V8 installations a small control unit activates the kick down solenoid when the brake pedal is released so that the car moves off in 1st gear. Other attributes of this transmission include ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mercedes-Benz First Series Automatic Transmission
The Mercedes-Benz first series of automatic transmission was produced from 1961 to 1983 in four- and three-speed variants for Mercedes-Benz passenger cars. In addition, variants for commercial vehicles were offered. Abstract The Mercedes-Benz first series of automatic transmission started off in 1961 with the K4A 025 (Kupplungs-4-Gang-Automatik bis 25 kpm Eingangsdrehmoment; clutch-4-gear-automatic with 181 ft·lb maximum input torque; without type designation) and was followed up by a family with a more reliable design. This started in 1964 with the K4B 050 (without type designation) and ended up in the K4C 025 and K4A 040 (type 722.2) as the four-speed automatic transmissions. Later, when the torque converter technique was fully established, the W3A 040 and W3B 050 (type 722.0) were launched as three-speed derivates for V8 engines. At the same time the fluid coupling for the smaller engines was replaced by a torque converter as well, which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Epicyclic Gearing
An epicyclic gear train (also known as a planetary gearset) consists of two gears mounted so that the center of one gear revolves around the center of the other. A carrier connects the centers of the two gears and rotates the planet and sun gears mesh so that their pitch circles roll without slip. A point on the pitch circle of the planet gear traces an epicycloid curve. In this simplified case, the sun gear is fixed and the planetary gear(s) roll around the sun gear. An epicyclic gear train can be assembled so the planet gear rolls on the inside of the pitch circle of a fixed, outer gear ring, or ring gear, sometimes called an ''annular gear''. In this case, the curve traced by a point on the pitch circle of the planet is a hypocycloid. The combination of epicycle gear trains with a planet engaging both a sun gear and a ring gear is called a ''planetary gear train''.J. J. Uicker, G. R. Pennock and J. E.

Mercedes-Benz W123
The Mercedes-Benz W123 is a range of executive cars produced by German manufacturer Mercedes-Benz from November 1975 to January 1986. The W123 models surpassed their predecessor, the Mercedes-Benz W114, as the most successful Mercedes, selling 2.7 million units before production ended in the autumn of 1985 for the saloon/sedan versions and January 1986 for coupés and estates/station wagons. Following a slow production build-up during the first year, customers who placed their orders faced a lengthy waiting period of nine to twelve months. A black market emerged for the customers who were willing to pay more for immediate delivery. The slightly used W123 commanded about 5,000 Deutsche Mark premium over its original sale price. Like its predecessors, the W123 gained the reputation of being well built and reliable. Many taxi companies chose the W123, and they were a common sight in Germany. Reaching 500,000 or 1,000,000 km with only minor mechanical issues was common with W123 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mercedes-Benz G-Class
The Mercedes-Benz G-Class, sometimes colloquially called the G-Wagen (as an abbreviation of Geländewagen) is a four-wheel drive automobile manufactured by Magna Steyr (formerly Steyr-Daimler-Puch) in Austria and sold by Mercedes-Benz. Originally developed as a military jeep, military off-roader, later more luxury car, luxurious models were added to the line. In certain markets, it has been sold under the Puch name as Puch G until 2000. The G-Wagen is characterised by its boxy styling and body-on-frame construction. It uses three fully locking differentials, one of the few passenger car vehicles to have such a feature.
