propeller shaft will be attached lo the ring gear pinion shaft. When the propeller shaft turns the ring gear pinion, the pinion will turn the ring gear. The ring gear, in turn will revolve the differential case and pinion shaft. Tile axle side gears will still NOT TURN. By adding two differential pinion gears (the differential pinion shaft will pass through these gears) that mesh with the side gears, the revolving case will turn the axle side gears with it. DIFFERENTIAL ACTION The propeller shaft turns tile ring gear pinion shaft. The ring gear pinion turns the ring gear which, in turn, revolves the differential case. When the case turns, the differential pinion shaft turns with it. As the differential pinions are mounted on this shaft, they are forced to move with the case. Being meshed with the axle side gears, the pinions will pull the axle side gears along with them. When the car is moving in a straight line, the ring gear is spinning the case. The differential pinions and axle side gears arc moving around with the case, with no movement between the teeth of the pinions and axle side gears. The entire movement is like a solid rounding a turn, the case continues whirlingand pulling the pinions around on the shaft. As the outer wheel must turn faster, the outer axle side gear is now moving faster than the inner axle side gear. The whirIing pinions not only pull on both 7 axle sidegears, but now begin to rotate on their shaft. Auto Mechanics Fundamentals while walking in the axle side gears. This allows them to pull on both axle side gears, while at the same time, pensating for difference in speed by rotating around their shaft. You can see detail A, the car is moving in a straight line. The pinion is pulling both gears, but it is not turning. In B, the right side axle gear is moving faster than the left axle gear. The pinion gear is still moving at the same speed. It is still pulling on both gears, but has now started to turn on the pinion shaft. This turning action, added to the forward rotational speed of the shaft, has caused the righthand side gear to speed up and actually begin to pass the pinion shaft. Study Figs. 169 and 1610. The reversewalking effect on the lefthand side gear has caused it to slow down. The differential action adjusts itself to any axle speed variation. If one wheel begins to slip, the axle on firm ground will stand still. The case continues spinning the pinions, but they will merely walk around the stopped axle gear and impart the torque to the spinning axle. A special traction differential is often used to overe this tendency. It will be covered later in this chapter. DIFFERENTIAL CARRIER AND BEARINGS A heavy and rigid section is bolted to the housing. It contains the pinion gear, shaft, and bearings. This is termed the DIFFERENTIAL CARRIER. Two large bearing holders are provided to support the spinning differential case. These are termed CARRIER BEARINGS. In some applications, the carrier is made as a solid part of the axle housing. All the ponent parts of the axle housing, axles and differential SPECIAL TRACTION DIFFERENTIAL To avoid。
