Differential gear, in automotive mechanics, gear arrangement that permits power from the engine to be transmitted to a couple of driving wheels, dividing the force equally between them but permitting them to check out paths of different lengths, as when turning a corner or traversing an uneven road. On a straight street the tires rotate at the same swiftness; when turning a part the outside wheel has farther to go and can turn faster compared to the inner steering wheel if unrestrained.
The components of the Ever-Power differential are demonstrated in the Figure. The power from the tranny is sent to the bevel band equipment by the drive-shaft pinion, both of which are held in bearings in the rear-axle housing. The case is an open boxlike structure that is bolted to the ring gear and contains bearings to support a couple of pairs of diametrically opposite differential bevel pinions. Each wheel axle is attached to a differential side gear, which meshes with the differential pinions. On a straight road the wheels and the medial side gears rotate at the same speed, there is absolutely no relative motion between your differential part gears and pinions, and they all rotate as a device with the case and ring gear. If the vehicle turns to the left, the right-hand steering wheel will be forced to rotate faster than the left-hand wheel, and the side gears and the pinions will rotate in accordance with each other. The ring equipment rotates at a acceleration that is add up to the mean acceleration of the still left and right wheels. If the tires are jacked up with the transmission in neutral and one of the wheels is turned, the contrary wheel will turn in the opposite path at the same acceleration.
The torque (turning instant) transmitted to both wheels with the Ever-Power differential may be the same. Consequently, if one wheel slips, as in ice or mud, the torque to the other wheel is reduced. This disadvantage could be overcome relatively by the use of a limited-slip differential. In one version a Differential Gear clutch connects one of the axles and the band gear. When one steering wheel encounters low traction, its inclination to spin is resisted by the clutch, thus providing greater torque for the other wheel.
OPEN DIFFERENTIAL:
A differential in its most basic form comprises two halves of an axle with a equipment on each end, linked together by a third gear creating three sides of a sq .. This is usually supplemented by a fourth gear for added strength, completing the square.
