  • Publication number: 20220289073
    Abstract: A working machine includes a battery unit; an electrical component; a radiator; an electrical-component cooling water channel along which cooling water delivered from an outflow port of the radiator is supplied to the electrical component and, after cooling the electrical component, circulates to an inflow port of the radiator; a switching unit provided on the electrical-component cooling water channel; and a battery cooling water channel along which the cooling water is supplied from the switching unit to the battery unit and, after cooling the battery unit, flows to the electrical-component cooling water channel. The switching unit is switchable between a first state of blocking a flow of the cooling water from the electrical-component cooling water channel to the battery cooling water channel and a second state of causing the cooling water to flow from the electrical-component cooling water channel to the battery cooling water channel.

  • Patent number: 10639983
    Abstract: A work vehicle includes an assist motor that is located opposite an engine with respect to a continuously variable transmission device. The assist motor has an output shaft that extends coaxially with a drive shaft of the continuously variable transmission device and is interlocked with the drive shaft. A motor support platform that supports the assist motor protrudes more outward than the continuously variable transmission device does in a lateral direction relative to a vehicle body. The motor support platform includes a slide movement mechanism, and the slide movement mechanism is configured to change the position at which the assist motor is attached, relative to the continuously variable transmission device, axially of the drive shaft, between a connected position and a disconnected position of the drive shaft and the output shaft.
