Abstract

DC60 (31/03/42) Consistently variable powertrain lubrication structure. The parts that will have to be lubricated of the continuously variable transmission parts with a structure that Simple and with less number of parts, 79 transmission chambers for containing variable transmission parts. Continuously, T is separated from the interior of the crankcase 14, the main transmission shaft 21 of the continuously variable transmission section, T passes through the cover 50 of the transmission 79, and the oil pump 81 is located at The end of the main transmission shaft 21, protruding from the cover 50, the oil pump 81, draws lubricant up from the sump 89 in the lower part of the transmission 79 through the oil pass 41 built into the case. 1 The lubricant is supplied to the transmission chamber 79 through the oil passages 211 and 212 made into the main transmission shaft 21 to lubricate the required parts. Continuously variable powertrain lubrication due to the transmission lubrication system Continuously variable power T is separated from the lubrication system for the E engine, it is possible to lubricate continuously variable powertrain T with the ideal amount of lubricant. Additionally, since the oil pump 81 is located at the end of the main transmission shaft 21, it is possible to bring the oil pump 81 closer to the continuously variable transmission T and thus the length Of the passage of lubricant is shortened Constructed for lubrication, continuously variable transmission sections can be lubricated.
