In order to conduct lubricating characteristic analysis on automobile continuously variable transmission, this paper divides overall model of transmission on the basis of the idea of blocking simulation. Then it generates shed oil model of differential mechanism and oil gathering model of oil groove. Set monitoring surface at the position of reverse gear shaft catcher groove in shed oil model of differential mechanism and oil groove in oil gathering model of oil groove to monitor its conditions of oil-taking. Consider the received flow from the two monitoring surfaces in simulation process as evaluation index of effects of transmission lubrication system, as well as conduct quantitative evaluation on lubricating effects of transmission lubrication system. The results show that all of working condition with second gear 1500rpm, reverse gear shaft and oil groove have comparative ideal lubrication effects on input axis.

Energy-saving and emission reduction has become the theme of the world. The wheel loader has a harsh working environment, complicated working conditions, and drastic changes in load, and the performance of the engine cannot be fully utilized. Therefore, the variable speed transmission of vehicles plays a vital role in improving the efficiency and performance of the vehicle. This paper establishes the general characteristic equations for the input coupling type of hydro-mechanical continuously variable transmission (HMCVT) based on the wheel loader and determines reasonable structural forms for connection of working conditions. It establishes the general efficiency equation for the reasonable structural form for efficiency analysis and presents a method of co-validation of the simulation and test for making the results of efficiency more accurate. Through this method, the transmission performance is more accurately analyzed, which provides an important guiding role and validation for the early design of HMCVT. Eventually, it gets reasonably optimized products and reduces the design cost and cycle.
