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 ...
A park by wire system engages the parking pawl of a transmission using electrical means, without the traditional mechanical system which involves linkages between the gear shifter and the transmission. Park-by-wire can be considered a part of a shift by wire system, as it shifts the transmission into park mode. [1]
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 ...
An automatic transmission with a manumatic function provides a greater level of control by allowing the driver to request an upshift or downshift at a specific time. This is usually achieved using "+" and "-" positions on the gear selector or with paddle-shifters mounted beside the steering wheel.
The Ford PowerShift are 6 and 7-speed dual-clutch automatic transmissions, produced for the Ford Motor Company. [1] The 6 speed PowerShift gearboxes were built by Getrag Ford Transmissions, a joint-venture with Getrag,. [2] PowerShift improves fuel efficiency by as much as 10 percent when compared to a conventional automatic transmission. [1]
Standard planetary automatic transmissions have caught up to DCT transmission shift times by also utilizing clutch to clutch shifts. For older transmissions, using a freewheel may reduce shift time, as it may not be necessary to use the clutch. A shift kit is also intended to reduce the shift time of a manual vehicle.
A direct-shift gearbox (DSG, German: Direktschaltgetriebe [1]) [2] [3] is an electronically controlled, dual-clutch, [2] 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 [2] or semi-manual gear selection.
The parking pawl locks the transmission's output shaft to the transmission casing by engaging a pawl (a pin) that engages in a notched wheel on the shaft, stopping it (and thus the driven wheels) from rotating. The main components of a parking pawl mechanism are the parking gear, parking pawl, actuator rod, cam collar, cam plate, pivot pin, and ...
