Title:
COMBINE HARVESTER
Document Type and Number:
WIPO Patent Application WO/2015/045437
Kind Code:
A1
Abstract:
A combine harvester provided with a speed-changing/power-transmitting device that comprises: a hydrostatic stepless speed-change unit into which the drive force from an engine is input and which changes the speed of the drive force; and a planetary power-transmission unit which combines the drive force from the engine and the output of the stepless speed-change unit and outputs the combined drive force to a travel device, wherein the weight of a power-transmission case can be inexpensively reduced. In this combine harvester, a stepless speed-change case section (95) of a power-transmission case (35), said stepless speed-change case section (95) housing a stepless speed-change unit (40), is integratedly formed with a planetary power-transmission case section (96) of the power-transmission case (35), said planetary power-transmission case section (96) housing a planetary power-transmission unit (50). The power-transmission case (35) has provided therein a partition wall (97) for separating a stepless speed-change chamber (95A) of the stepless speed-change case section (95), said stepless speed-change chamber (95A) housing the stepless speed-change unit (40), and a planetary power-transmission chamber (96A) of the planetary power-transmission case section (96), said planetary power-transmission chamber (96A) housing the planetary power-transmission unit (50).
