تعريف differential gear في الإنجليزية الإنجليزية القاموس.
An arrangement of bevel gears permitting the rotation of two shafts at two different speeds whilst supplying the same torque; used on the rear axles of automobiles to aid cornering
a bevel gear that permits rotation of two shafts at different speeds; used on the rear axle of automobiles to allow wheels to rotate at different speeds on curves
An arrangement of gears in an epicyclic train permitting the rotation of two shafts at different speeds, used on the rear axle of automotive vehicles to allow different rates of wheel rotation on curves. an arrangement of gears that allows one back wheel of a car to turn faster than the other when the car goes around a corner. In automotive mechanics, a gear arrangement that transmits power from the engine to a pair of driving wheels, dividing the force equally between them but permitting them to follow paths of different lengths, as when turning a corner or traversing an uneven road. On a straight road the wheels rotate at the same speed; when turning a corner the outside wheel has farther to go and would turn faster than the inner wheel if unrestrained. The automobile differential was invented in 1827; originally used on steam-driven vehicles, it was well known when internal-combustion engines finally appeared
