Dacia Easy-R
The Dacia Easy-R is an automated manual transmission used by Renault and Dacia that uses electro-mechanical actuation (rather than electro-hydraulic actuation) to automate the gear shifts. The ''Easy-R'' uses a traditional manual gearbox with a computer-controlled, electronic clutch; the gear shifts are automatic, and the need for a clutch pedal is eliminated. The number of parts has been reduced by a quarter, ensuring better reliability and simplified maintenance. ''Easy-R'' was available in the Logan, Logan MCV, and Sandero models. It was also available in the Duster and currently it is still available in the Renault Kwid and Renault Triber. There are two versions: the 5-speed ''JS3'' used in petrol engines and the 6-speed ''TS4 001'' used in diesel engines. The ''Dacia Easy-R'' gearbox was a resounding failure, and now Dacia has switched to using CVT gearboxes on its new models. Operation The ''Easy-R'' transmission has the following gears: ''R'', ''N'', ''D'', ''M+'', ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Automated Manual Transmission
The automated manual transmission (AMT) is a type of transmission for motor vehicles. It is essentially a conventional manual transmission but uses automatic actuation to operate the clutch and/or shift between gears. Many early versions of these transmissions that are semi-automatic in operation, such as ''Autostick'', which automatically control only the clutch — often using various forms of clutch actuation, such as electro-mechanical, hydraulic, pneumatic, or vacuum actuationhttp://hudsonterraplane.com/tech/other/DrivemasterServiceInformation.pdf — but still require the driver's manual input and full control to initiate gear changes by hand. These systems that require manual shifting are also referred to as clutchless manual systems. Modern versions of these systems that are fully automatic in operation, such as ''Selespeed'' and ''Easytronic'', can control both the clutch operation and the gear shifts automatically, by means of an ECU, therefore requiring no manu ...

Renault Triber
The Renault Triber is a mini MPV with three-row seating produced by the French car manufacturer Renault through its Indian subsidiary Renault India. It was introduced in India on 19 June 2019 and went on sale in August 2019. Development Developed under the body code "RBC", the Triber is built on top of the CMF-A platform like the Kwid. Despite that, the car is built with over 90% dedicated parts not shared with other Renault and Nissan vehicles since it is a larger and wider car in the CMF-A family. Laurens van den Acker, Corporate Design of Groupe Renault said the interior of the car is a "miracle" and refers to it as "a bit of a Leonardo da Vinci" as it offers three-row seating in a sub-four metre length. This was achieved by making the bonnet and engine bay as short as possible, making it not possible to fit a diesel engine or any larger petrol engine to the car. The car's width is spanning at to maximize cabin space, especially in the second row where three people had t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tiptronic
The modern usage of the automotive term manumatic denotes an automatic transmission that allows the driver to select a specific gear, typically using paddle-shifters, steering wheel-mounted push-buttons, or "+" and "-" controls on the gear selector. In the 1950s, the ''Automotive Products'' company in the United Kingdom produced an automated clutch system for automobiles called the ''Manumatic''. This system was installed in cars with a manual transmission, allowing them to be driven without needing to use a clutch pedal. Automatic transmissions Since the popularization of the hydraulic automatic transmission in the 1940s, many automatic transmissions have allowed indirect control of the gear selection, usually in the form of locking out higher gears. This was provided to allow engine braking on downhills or prevent the use of overdrive gears when towing and was typically achieved using positions such as "3", "2", and "1" on the gear selector. An automatic transmission with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semi-automatic Transmission
A semi-automatic transmission is a "theoretical" multiple-speed transmission where part of its operation is automated (typically the actuation of the clutch), but the driver's input would be required to launch the vehicle from a standstill and to manually change gears. Semi-automatic transmissions were exclusively used in motorcycles and are based on conventional manual transmissions or sequential manual transmissions, but use an automatic clutch system. But some semi-automatic transmissions have also been based on standard hydraulic automatic transmissions with torque converters and planetary gearsets. Names for specific types of semi-automatic transmissions include ''clutchless manual'', ''auto-manual'', ''auto-clutch manual'', and ''paddle-shift'' transmissions. These systems facilitate gear shifts for the driver by operating the clutch system automatically, usually via switches that trigger an actuator or servo, while still requiring the driver to manually shift gears.

Saab 900
The Saab 900 is a mid-sized automobile which was produced by Saab from 1978 until 1998 in two generations; the first from 1978 to 1993, and the second from 1994 to 1998. The first-generation car was based on the Saab 99 chassis, though with a longer front end . The 900 was produced in 2- and 4-door sedan, and 3- and 5-door hatchback configurations and, from 1986, as a cabriolet (convertible) model. There were single- and twin-Zenith carburettor; fuel injected, and turbocharged engines, including both Full Pressure Turbo (FPT), and, in European models during the early 1990s, Low Pressure Turbos (LPT). Saab 900 "Classic" Overview The Saab 900 is a front-engine, front-wheel-drive mid-size car with a longitudinally mounted, 45-degree slanted, inline four-cylinder engine, double wishbone front suspension and beam-axle rear suspension.

Direct-Shift Gearbox
A direct-shift gearbox (DSG, german: Direktschaltgetriebe) is an electronically-controlled, dual-clutch, multiple-shaft, automatic gearbox, in either a transaxle or traditional transmission layout (depending on engine/drive configuration), with automated clutch operation, and with fully-automatic or semi-manual gear selection. The first dual-clutch transmissions were derived from Porsche in-house development for the Porsche 962 in the 1980s. In simple terms, a DSG automates two separate "manual" gearboxes (and clutches) contained within one housing and working as one unit. It was designed by BorgWarner and is licensed to the Volkswagen Group, with support by IAV GmbH. By using two independent clutches, a DSG can achieve faster shift times and eliminates the torque converter of a conventional epicyclic automatic transmission. Overview Transverse DSG At the time of launch in 2003, it became the world's first automated dual-clutch transmission in a series-production car, i ...

Automatic Transmission
An automatic transmission (sometimes abbreviated to auto or AT) is a multi-speed transmission used in internal combustion engine-based motor vehicles that does not require any input from the driver to change forward gears under normal driving conditions. It typically includes a transmission, axle, and differential in one integrated assembly, thus technically becoming a transaxle. The most common type of automatic transmission is the hydraulic automatic, which uses a planetary gearset, hydraulic controls, and a torque converter. Other types of automatic transmissions include continuously variable transmissions (CVT), automated manual transmissions (AMT), and dual-clutch transmissions (DCT). An electronic automatic transmission (EAT) may also be called an electronically controlled transmission (ECT), or electronic automatic transaxle (EATX). A hydraulic automatic transmission may also colloquially called a " slushbox" or simply a "torque converter", although the latter term c ...

Torque Converter
A torque converter is a type of fluid coupling that transfers rotating power from a prime mover, like an internal combustion engine, to a rotating driven load. In a vehicle with an automatic transmission, the torque converter connects the power source to the load. It is usually located between the engine's flexplate and the transmission. The equivalent location in a manual transmission would be the mechanical clutch. The main characteristic of a torque converter is its ability to increase torque when the output rotational speed is so low that it allows the fluid coming off the curved vanes of the turbine to be deflected off the stator while it is locked against its one-way clutch, thus providing the equivalent of a reduction gear. This is a feature beyond that of the simple fluid coupling, which can match rotational speed but does not multiply torque and thus reduces power. Hydraulic systems By far the most common form of torque converter in automobile transmissions is the hydr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Continuously Variable Transmission
A continuously variable transmission (CVT) is an automatic transmission that 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. CVTs are used in cars, tractors, side-by-sides, motor scooters, snowmobiles, bicycles, and earthmoving equipment. The most common type of CVT uses two pulleys connected by a belt or chain; however, several other designs have also been used at times. Types Pulley-based The most common type of CVT uses a V-belt which runs between two variable-diameter pulleys. The pulleys consist of two cone-shaped halves that move together and apart. The V-belt runs between these two-halves, so the effective diameter of the pulley is dependent on the distance between the two-halves of the pulley. The V-shape ...
