US 2001/0018382 A1 · Lubricating oil supply system for infinitely variable transmission

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. The oil pump which is driven by the transmission shaft is located on the wall section.
