Abstract
A working vehicle includes a first device chamber and a second device chamber in front and rear portions of a vehicle body and a first partition and a second partition partitioning the first device chamber and the second device chamber from surroundings inside the vehicle body, the first device chamber includes devices, e.g., a hydraulic pump, an electric motor, and an inverter, generating heat and becoming relatively high temperature or having relatively high heat resistance, the second device chamber includes devices, e.g., an on-board charger, a battery pack, a converter, and a controller, generating heat and not becoming relatively high temperature or having relatively low heat resistance, and the first device chamber and the second device chamber are separately cooled by cooling fans.
Claims4
A working vehicle having:
- a vehicle body;
- a travel unit;
- a working unit working by a hydraulic pressure;
- and
- an electric motor that serves as a drive source for the travel unit or the working unit, wherein
- the working vehicle comprises:
- a first device chamber provided in a front portion of the vehicle body;
- a second device chamber provided in a rear portion of the vehicle body;
- a first partition that partitions the first device chamber from surroundings inside the vehicle body;
- and
- a second partition that partitions the second device chamber from the surroundings inside the vehicle body, wherein
- the first device chamber comprises
- devices that generate heat and that become relatively high temperature or have relatively high heat resistance, the device including:
- a hydraulic pump that supplies hydraulic oil to the travel unit or the working unit;
- an electric motor that drives the hydraulic pump;
- and
- an inverter that controls a driving voltage of the electric motor, wherein
- the second device chamber comprises
- devices that generate heat and that do not become relatively high temperature or have relatively low heat resistance, the device including:
- an on-board charger that supplies electric power for driving the electric motor;
- a battery pack having a rechargeable battery that stores the electric power supplied from the on-board charger;
- a converter that converts an output voltage of the battery pack;
- and
- a controller, and wherein
- the first device chamber and the second device chamber are separately cooled by different fans, respectively,
- wherein the first device chamber has a first air inlet in the front portion of the vehicle body and a first air outlet in one side portion of the vehicle body.
