QLN tractors are with advanced technology in double clutch. And now, let us together to learn what the exact double clutch technology is.

Double clutching (also called double declutching) is a method of shifting gears used primarily for vehicles with an unsynchronized manual transmission, such as commercial trucks and specialty vehicles. Double clutching is not necessary in a vehicle that has a synchronized manual transmission.

With this method, instead of pushing the clutch in once and shifting directly to another gear, the driver first engages the transmission in neutral before shifting to the next gear. The clutch is pressed and released with each change.

Technique

The double clutching technique involves the following steps:

The throttle (accelerator) is released, the clutch pedal is pressed, and the gearbox is shifted into neutral.

The clutch pedal is then released, the driver matches the engine RPM to the gear RPM either using the throttle (accelerator) (when changing to a lower gear) or waiting for RPM to decrease (when changing to a higher gear) until they are at a level suitable for shifting into the next gear.

At the moment when the revs between engine and gear are closely matched, the driver then instantly presses the clutch again to shift into the next gear. The result should be a very smooth gear change.

Manual transmission shifting

In a gearbox with neutral between each gear, a typical shift actually involves two gear changes, once into neutral, and again into the next gear. During any shift, disconnecting drive components via a clutch properly unloads the engine and transmission of undue pressure applied by the opposing components.

Fully utilizing the clutch for each shift out of, and then into each gear is double (de)clutching. Due to the absence of a neutral spacing, double clutching is ill-advised for sequential gear changes, as in a fully sequential gearbox such as a typical motorcycle.
