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.
A commercial push-button-based electronic shift selector made by Allison Transmission. Shift-by-wire is an automotive concept or system that employs electrical or electronic connections that replace the mechanical connection between the driver's gearshift mechanism and the transmission.
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 ...
The blue valve body is visible in-line with the pipe. The valve actuator opens or closes the butterfly disc of the valve based on electrical signals sent to the actuator. Another valve actuator is visible in the background, with windows to indicate the valve position. A valve actuator is the mechanism for opening and closing a valve. Manually ...
Names for specific types of semi-automatic transmissions include clutchless manual, [3] auto-manual, [4] [5] auto-clutch manual, [6] [7] and paddle-shift transmissions. [ 8 ] [ 9 ] [ 10 ] These systems facilitate gear shifts for the driver by operating the clutch system automatically, usually via switches that trigger an actuator or servo ...
The piston or other reciprocating part is directly coupled to a sliding yoke with a slot that engages a pin on the rotating part. The location of the piston versus time is simple harmonic motion , i.e., a sine wave having constant amplitude and constant frequency, given a constant rotational speed .
The Ford unit is a six-speed with one clutch acting on reverse, first, third, and fifth gears, and the other used for second, fourth, sixth gears. As the first gear is engaged, the 2-4-6 clutch is disengaged and the second gear cogs are engaged. At the appropriate time, the R-1-3-5 clutch is disengaged and the 2-4-6 clutch is engaged.
A majority of North American-spec vehicles sold in the U.S. and Canada had a 3-speed column-mounted shifter—the first generation Chevrolet/GMC vans of 1964–70 vintage had an ultra-rare 4-speed column shifter. The column-mounted manual shifter disappeared in North America by the mid-1980s, last appearing in the 1987 Chevrolet pickup truck ...
