LUBRICATING APPARATUS FOR EXTENSION HOUSING

摘要

PURPOSE:To obtain the good lubrication with the simple constitution by supplying lubricating oil branched from a line-pressure oil passage through a pipe means onto the bearing part of an extension housing an devising the connection structure of the pipe means. CONSTITUTION:The captioned lubricating apparatus 1 for feeding the stable amount of lubricating oil into the bearing part 5 of the extension housing 4 of an automatic speed change gear 2 is installed in a transmission case 22 and is equipped with a line-pressure oil passage 12 for feeding the line pressure into a hydraulic servo not shown in the figure of a speed change gear 21 through an oil chamber 11 from a valve body 23. Further, the captioned apparatus is equipped with a lubricating-oil taking-out passage 13 which is branched midway from the oil passage 12 and has an orifice 13, and is equipped with a pipe 18 which connects the oil passage 13 with the oil hole 26A of a bearing 26. Further, the edge part of the taking-out oil passage 13 side of the pipe 18 is installed through a packing 16 onto a seal seat 15 installed onto the housing 4 side of the joint surface 10 between the case 22 and the housing 4.
