During any shift, disconnecting drive components via a clutch unloads the force from the opposing components from the engine and transmission. 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 ...
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 ...
Shift time refers to the time interval between gear changes in a transmission. This interval is the time in which power delivery is transferred to the next selected gear, and engine speed is reduced or increased to synchronize the speed of the next gear. Shift time is usually in reference to motor vehicles, but can apply to any gearbox.
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.
Clutch control is the controlling of the speed of a manual transmission vehicle by partially engaging the clutch plate, using the clutch pedal instead of (or in conjunction with) the accelerator pedal. The purpose of a clutch is in part to allow such control; in particular, a clutch provides transfer of torque between shafts spinning at ...
When the clutch pedal is depressed, the system waits for the user to either move the shifter to a different position or to re-engage the clutch. If a new gear is never selected but the clutch has been depressed long enough for the engine to lose speed, the system will bring the engine back to speed for the same gear if the driver begins to ...
Unlike during a normal gear change, in a powershift the driver does not let off the accelerator. The clutch is briefly depressed while the shift lever is rapidly shifted into a higher gear, keeping the engine in its power band (unlike speed-shifting, where the throttle is let off very quickly, simultaneously depressing the clutch and shifting ...
