Shifting in this manner is also used with synchronous manual transmissions, particularly after a clutch failure, to prevent destroying the synchromeshes with the power of the engine. Drivers can shift non-synchronous transmissions without using the clutch by bringing the engine to exactly the right RPM in neutral before attempting to complete a ...
In 1891, the French Panhard et Levassor automobile used a three-speed manual transmission and is considered to have set the template for multi-speed manual transmissions in motor vehicles. [3] [4] This transmission used a sliding-gear design without any form of speed synchronization, causing frequent grinding of the gear teeth during gear ...
A manual transmission (MT), also known as manual gearbox, standard transmission (in Canada, the United Kingdom and the United States), or stick shift (in the United States), is a multi-speed motor vehicle transmission system where gear changes require the driver to manually select the gears by operating a gear stick and clutch (which is usually ...
In other cases, the internal clutch actuator may be completely electric, where the main clutch actuator is powered by an electric motor or solenoid, or even pneumatic, where the main clutch actuator is a pneumatic actuator that disengages the clutch. A clutchless manual system, named the Autostick, was a semi-automatic transmission introduced ...
1931 Bugatti Type 51 cockpit, with Wilson preselector gearbox. The most common type of pre-selector gearbox was the Wilson, which used an epicyclic design. [5] [6] A precursor to the Wilson gearbox was the manually-controlled epicyclic gearbox used in the 1901–1904 Wilson-Pilcher cars built in the United Kingdom.
Automated manual transmissions can be semi-automatic or fully-automatic in operation. Several different systems to automate the clutch and/or shifting have been used over the years, but they will generally use one of the following methods of actuation for the clutch and/or shifting: hydraulic or electro-hydraulic actuation, [12] electro-mechanical, [13] pneumatic, [6] [14] [15] electromagnetic ...
Gear shift lever on a motorcycle (above the toe of the rider's boot) A sequential manual transmission is unsynchronized, and allows the driver to select either the next gear (e.g. shifting from first gear to second gear) or the previous gear (e.g., shifting from third gear to second gear), operated either via electronic paddle-shifters mounted behind the steering wheel or with a sequential ...
It was a hybrid manual transmission equipped with a torque converter, like an automatic. Although Hy-Drive cars had a clutch pedal like a traditional manual transmission, it was only used to put the car in gear. Once underway, the driver could upshift and downshift using the gear shift without using the clutch or even lifting off the accelerator.
