The final drive casing of above-mentioned automobile drive axle, meeting on the requirement basis of housings support rigidity, reduces the bevel housing wall thickness and reduced final drive casing weight, thereby reduced the kinetic energy rejection of transmission system.
Preferably, be provided with oil duct and oil collecting structure in final drive casing, oil collecting structure comprises oil-collecting groove and end points, and end points comprises left end point, right endpoint.The oil-collecting groove is located on bearing support mounting hole lower wall circumferential surface, left and right end points sealing, and oil duct is positioned at the left and right end points of oil-collecting groove and with bearing support mounting hole sidewall, is communicated with.This structure improves the oil storage of oil duct and excessively oily ability greatly, thereby has improved the lubrication effect to bearing.
More preferably, the left and right end points tangent plane of oil collecting structure is trapezoidal, and during this structure, the oil storage of oil duct and excessively oily ability the best, best to the lubrication effect of bearing.
Preferably, be provided with graphic structure in housing outer surface, the graphic structure profile protrudes or is depressed in surface of shell, is positioned at inclination cambered surface housing or inclination cambered surface housing and angled section housing and seamlessly transits part, and this graphic structure can be the effect that word, pattern have vibration and noise reducing.
The utility model compared with prior art, by changing Cross section Design, weight and the chamber internal volume of final drive casing have been reduced, reduced the kinetic energy rejection of volume read-out and transmission system, design by oil duct and oil collecting structure has improved the lubrication effect to bearing, sign structure design by housing outer surface, reach the effect of vibration and noise reducing, by at bearing of pinion pilot mounting hole outer wall and bearing support mounting hole inwall, stiffening rib being set, guaranteed the rigid support to bevel gear, reduce simultaneously final drive casing weight, reduced the kinetic energy rejection of transmission system.
