Abstract
A working vehicle includes a hydraulic transmission chamber to accommodate a hydraulic pump and a hydraulic motor driven by fluid delivered from the hydraulic pump, and a primary transmission casing to accommodate a primary transmission that includes an input gear to receive power from a prime mover and a transmission gear to transmit the power transmitted from the input gear to the hydraulic pump. The primary transmission casing is adjacent to the hydraulic transmission chamber. An interior of the primary transmission casing is separated from the hydraulic transmission chamber.
Claims7
A working vehicle comprising:
- a hydraulic transmission chamber to accommodate a hydraulic pump and a hydraulic motor driven by fluid delivered from the hydraulic pump;
- a primary transmission casing to accommodate a primary transmission including an input gear to receive power from a prime mover and a transmission gear to transmit power from the input gear to the hydraulic pump, the primary transmission casing being adjacent to the hydraulic transmission chamber;
- and
- an orifice to allow the hydraulic transmission chamber and an interior of the primary transmission casing to communicate with each other, wherein
- the interior of the primary transmission casing is separated from the hydraulic transmission chamber;
- and
- the hydraulic transmission chamber and the interior of the primary transmission casing are separated from each other such that fluid in the hydraulic transmission chamber does not flow into the primary transmission casing through or in any portion except for the orifice.
