LUBRICATING DEVICE OF A DIFFERENTIAL GEAR OF A COMMERCIAL VEHICLE TO PREVENT THE DAMAGE OR STACKING OF AN INTER DEEPER GEAR, A SPIDER, AND A BEARING THROUGH SUPPLYING AND PUMPING BY A LUBRICATING PUMP BY FORCE

摘要

PURPOSE: A lubricating device of a differential gear of a commercial vehicle is provided to improve the abrasion resistance and heat resistance of a differential gear operated frequently under sever differential conditions such as an uphill road or a rough road through lubricating an inter differential gear, a spider, and a bearing.;CONSTITUTION: A lubricating device of a differential gear of a commercial vehicle comprises an input shaft(1), an output shaft(4), and an inter deeper gear. The input shaft receives power from an engine. The output shaft receives power from the input shaft and transfers the power to a rear differential gear. The inter deeper gear includes a rotation member between front and rear differential gears. The lubricating pump(10) of the lubricating device of a differential gear is installed between the input shaft and the output shaft. The lubricating pump transfers the input shaft to the inter deeper gear through being driven by the rotation member and pumping up lubricating oil.;COPYRIGHT KIPO 2012
