Transmission gear for agricultural tractor

Abstract

Abstract PURPOSE:To prevent exposure of charge pump or oil path from the gear mission by containing a charge pump in a partitioned wall section while making an oil path through said wall section. CONSTITUTION:A charge pump 18 is fitted in an assembling hole made in perpendicular direction against a rotary shaft 16a to be supported through the partition wall section 3a of gear mission 16 onto the partition wall section 3a. The greater part of an oil path 21 communicating between the charge pump 18 and the containing space of gear mission 16 and an oil path 23 communicating between the charge pump 18 and a stepless speed changer 12 are made through said wall section 3a. Consequently, the charge pump 18 or the oil paths 21, 23 will never expose from the gear mission case 3 resulting in reduction of the overall size of mission.
