The Manumatic was installed in cars with a manual transmission, allowing them to be driven without needing to use a clutch pedal. [2] According to the modern use of the term it would be classified as an automated manual transmission and not as a manumatic transmission.
The clutch brake not only slows or stops the idle gear axis but can also prevent shifting into gear until the clutch pedal is released a few centimetres (or inches) off the floor. In order to shift into gear, the clutch must be halfway off the floor, otherwise, the clutch brake will prevent the transmission from being shifted into or out of gear.
The best-known is the fluid flywheel, used for touring cars such as the Daimler (Armstrong Siddeley used a centrifugal clutch). [2] Sports cars used a Newton centrifugal clutch. [2] This was a multiple plate dry clutch, similar to racing manual clutches of the time, but with the pressure plate centrifugally actuated to engage at around 600rpm. [17]
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 ...
The 1941 Chrysler M4 Vacamatic transmission was a two-speed manual transmission with an integral underdrive unit, a traditional manual clutch, and a fluid coupling between the engine and the clutch. [51] [52] [53] The two-speed transmission had "high" and "low" ranges, and the clutch was used when the driver wanted to switch between ranges. For ...
Float shifting can reduce clutch wear because it is used so much less (only for starting from a standstill). Conversely, improper engagement of a gear (when the engine and transmission speeds aren't matched) can cause wear on the synchros and lockouts, and damage the gears by physically grinding them together due to a difference in speed.
Cars with a Saxomat clutch did not have a clutch pedal. The Saxomat consisted of two independent systems: the centrifugal clutch, and the servo clutch. The centrifugal clutch was engaged above a certain engine speed by centrifugal force acting on spinning weights inside the clutch, similar to a centrifugal governor .
In manual transmission cars, the dead pedal is designed to promote a smoother actuation of the clutch by keeping the driver's foot in the same plane as the pedal. [1] Automatic transmission cars can also benefit from the dead pedal because it prevents fatigue by offering a stable inclined surface on which the driver can place their foot. Even ...
