The differential planetary gasket has a full radian, which has stronger wear resistance.(7) The composite material copper sleeve protects the gear and cross shaft more effectively, and effectively prevents the gear from burning.(8) The original nut is used, and the thread has stronger hardness. Anaerobic thread-locking adhesive is applied to prevent the nut from falling off.(9) The differential cross shaft adopts 22CrMnMo mechanical strength, which better strengthens the fatigue resistance of the cross shaft, and the plane structure of the shaft body makes the lubricating oil smoother.Factory Show Brand CulturePackaging & ShippingWorking PrincipleWorking principle of interaxle differential assembly1. When turning, due to the sliding drag of the outer wheel and the sliding rotation of the inner wheel, the two driving wheels will produce additional forces in opposite directions, resulting in different speeds of the wheels on both sides, which destroys the balance relationship between the three, and is reflected on the half shaft gear through the half shaft, forcing the planetary gear to rotate and slowing down the speed of the inner half shaft, The speed of the outer half axle is accelerated, so as to realize the difference of wheel speed on both sides. If the drive wheels on both sides of the drive axle are rigidly connected with a whole shaft, the two wheels can only rotate at the same angle. In this way, when the vehicle turns to travel, because the outer wheel moves a larger distance than the inner wheel, the outer wheel will slip while rolling, while the inner wheel will slip while rolling. Even if the vehicle runs in a straight line, it will cause wheel sliding due to uneven road surface or unequal tire rolling radius (tire manufacturing error, different wear, uneven load or unequal air pressure), which will not only aggravate tire wear, increase power and fuel consumption, but also make the vehicle difficult to turn and poor braking performance. In order to prevent the wheel from sliding as much as possible, the structure must ensure that each wheel can rotate at different angles.2. When the vehicle goes straight, the resistance of the left and right wheels is equal. The planetary gears in the differential housing only revolve with the housing rather than rotate.3. When the vehicle turns, the inner wheel will produce greater resistance. Different forces on the half shafts on both sides will make the middle planetary gear rotate, and there will be speed difference between the half shafts on both sides. The outside wheel turns faster than the inside wheel, so that the vehicle can turn smoothly. Composition structure of differential assembly1.The automobile differential assembly can make the left and right (or front and rear) drive wheels rotate at different speeds. It is mainly composed of left and right half shaft gears, two planetary gears and gear carrier. Ordinary differential assembly is composed of planetary gear, planetary carrier (differential housing), half shaft gear and other parts.2. The power of the engine enters the differential mechanism through the transmission shaft, directly drives the planetary gear carrier, and then the planetary gear drives the left and right half shafts to drive the left and right wheels respectively. The design requirements of differential mechanism meet: (left half shaft speed) + (right half shaft speed) = 2 (planet carrier speed). When the car goes straight, the speeds of the left and right wheels and the planetary carrier are equal and in a balanced state. When the car turns, the balance state of the three is destroyed, resulting in the decrease of the speed of the inner wheel and the increase of the speed of the outer wheel.The function of differential assembly1.Differential assembly is a differential transmission mechanism, which is used to distribute torque between the two output shafts and ensure that the two output shafts may rotate at different angular speeds. It is used to ensure the power transmission of each driving wheel under various motion conditions and avoid slipping between th
