Disengaging the clutch for each shift out of, and then into, each gear is double clutching or declutching. [4] Due to the absence of a neutral spacing, double-clutching is impossible for sequential gear changes, as with a fully sequential gearbox used in motorcycles and racecars. The double-clutching technique involves the following steps:
A dual-clutch transmission (DCT) (sometimes referred to as a twin-clutch transmission) is a type of multi-speed vehicle transmission system, that uses two separate clutches for odd and even gear sets. [1] The design is often similar to two separate manual transmissions with their respective clutches contained within one housing, and working as ...
All hail the Foaminator! From bumper blaster to banana foamer, an automatic carwash is a drive-through Rube Goldberg machine.
Instead of a sprag or roller clutch, Honda's older transmissions rely on pressure circuits to modulate line pressure to change gears. [3] Honda was forced to invent their new system due to the vast array of patents on automatic transmission technology held by BorgWarner and others.
The Honda Passport is a line of sport utility vehicles (SUV) from the Japanese automaker Honda. Originally, it was a rebadged version of the Isuzu Rodeo, a mid-size SUV sold between 1993 and 2002. It was introduced in 1993 for the 1994 model year as Honda's first entry into the growing SUV market of the 1990s in the United States.
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 average manual car driver takes between 500 ms and 1 s to perform vertical gear changes (i.e. 1st-2nd, 3rd-4th, 5th-6th) and 1 - 2 s to perform horizontal gear changes (i.e. 2nd-3rd, 4th-5th). Shift time is also dependent on gear throws (distance between gears), ease of movement, ergonomics of the gear stick , and gearbox condition.
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.
