Abstract

A lubricating oil supply system for an infinitely variable transmission wherein the infinitely variable transmission has a transmission shaft provided with a lubricating oil path and is rotatably mounted through the wall section of a casing. The infinitely variable transmission is housed in a transmission case partly defined by the wall section. An input rotary member is provided that is relatively unrotatably connected to the transmission shaft on the outside of the transmission case. An oil pump is provided for supplying lubricating oil to the lubricating oil path. The oil pump is located in the casing. In this infinitely variable transmission, the oil passage from the oil pump to the lubricated portion of the infinitely variable transmission is simplified in structure and the oil passage is substantially reduced in length, thereby enabling a decrease in the length of the transmission shaft.

Description

technical field [0001] The present invention relates to an improvement of a lubricating oil supply device for a continuously variable transmission, which has a transmission shaft that can freely rotate through a wall portion provided on a casing, is freely rotatably supported on the casing, and is provided with a lubricating oil passage The continuously variable transmission is accommodated in a transmission chamber defined by the above-mentioned wall part and formed on the above-mentioned case. Outside the above-mentioned transmission chamber, an input rotating member is connected to the transmission shaft in a non-rotatable manner on the case. Equipped with an oil pump that supplies lubricating oil to the aforementioned lubricating oil passage. Background technique [0002] Conventionally, such lubricating oil supply devices have been known in the art, for example, Japanese Patent Application Laid-Open No. 11-79054 and Japanese Patent Laid-Open No. 11-270641 disclose such ...
