This unit was an early semi-automatic transmission, based on the design of a conventional manual transmission, which used a servo-controlled vacuum-operated clutch system, with three different gear shifting modes, at the touch of a button; manual shifting and manual clutch operation (fully manual), manual shifting with automated clutch ...
The internal clutch actuator in a semi-automatic transmission can be powered by either hydraulic, pneumatic, or electric means. [6] [7] Later examples of clutchless manual transmissions used in road cars include the Saab Sensonic transmission, used in the 900 NG, and the Ferrari Valeo auto-manual transmission, used in the Mondial T.
Technically, it consists of the standard (manual) 6-speed gearbox with the standard clutch and adds an electronically controlled hydraulic (robotic) that actuates both gear and clutch. In its current incarnation, it can be operated via paddle-shifters from the steering wheel or via a "joystick" like a conventional sequential manual gearbox ...
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 ...
Automatic – once placed in drive (or any other 'automatic' selector position), it automatically selects the gear ratio dependent on engine speed and load; Basically there are two types of engine installation: In the longitudinal direction, the gearbox is usually designed separately from the final drive (including the differential). The ...
An automated manual transmission (AMT) is essentially a conventional manual transmission that uses automatic actuation to operate the clutch and/or shift between gears. Many early versions of these transmissions were semi-automatic in operation, such as Autostick , which automatically control only the clutch , but still require the driver's ...
The AP automatic transmission is a 4-speed automatic transmission unit developed by Automotive Products and the British Motor Corporation specifically for use in the Mini.. It was unique in that not only was it one of the first transverse mounted automatic transmission units tailored for front wheel drive, it was one of the smallest in order to be used in the transmission-in-sump installation ...
The 9HP is only 0.24 inches (6 mm) longer than, and weighs 16.5 lbs (7.5 kg) less than, the outgoing six-speed transmission. The compact packaging is achieved by using a number of innovative design features: a new compact hydraulic vane-type pump, two patented dog clutches, [3] which replace bulkier conventional clutch packs, and a nested gear set.
