Double Clutch

A double clutch (also called a double declutch) is a method of shifting gears primarily used for vehicles with an unsynchronized manual transmission, such as commercial trucks and specialty vehicles.

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

Famous quotes containing the words double and/or clutch:

    Well, I had gone and spoiled it again, made another mistake. A double one in fact. There were plenty of ways to get rid of that officer by some simple and plausible device, but no, I must pick out a picturesque one; it is the crying defect of my character.
    Mark Twain [Samuel Langhorne Clemens] (1835–1910)

    We have no participation in Being, because all human nature is ever midway between being born and dying, giving off only a vague image and shadow of itself, and a weak and uncertain opinion. And if you chance to fix your thoughts on trying to grasp its essence, it would be neither more nor less than if your tried to clutch water.
    Michel de Montaigne (1533–1592)
