摘要： [Problem] To provide a hybrid work vehicle which is simple in configuration, good in ease of mounting on a vehicle and capable of efficiently transmitting motive power. [Solution] The hybrid work vehicle includes: an engine (1); a hydraulic pump (4) which is driven by the engine; a work device (5) which is disposed at the front of the vehicle and performs work using the hydraulic pump as a drive source; a motor/generator (6) which generates electric power by use of the torque of the engine; and a travel drive device which causes the vehicle to travel by rotating and driving wheels by use of the electric power generated by the motor/generator. The hybrid work vehicle is steered while the vehicle bends by way of a center joint (15). The travel drive device includes: a plurality of electric motors (21 and 22) ; and a propeller shaft (8) which is linked with the plurality of electric motors and transmits motive power from the plurality of electric motors to the wheels. The plurality of electric motors are disposed at the front and rear sides of the center joint with the center joint being disposed therebetween.

摘要： A hybrid wheel loader is provided, the hybrid wheel loader achieving high work efficiency even with a short supply of power to be output relative to a vehicle power requirement. The hybrid wheel loader includes a motor generator 6 connected to an engine (1), a hydraulic pump (4) connected to the motor generator, a hydraulic actuator (51, 52, 53) driven by hydraulic oil supplied from the hydraulic pump, a travel electric motor (9) for driving wheels (61), and an electrical storage device (11) connected to each of the motor generator and the electrical storage device via respective inverters (7, 10). When a total requirement power value is greater than a hybrid output upper limit value, either one of a hydraulic requirement power value Pf and a travel requirement power value Prun is limited according to an operation of the wheel loader to thereby set the total requirement power value to a value equal to, or less than, the hybrid output upper limit value.
