<p>A hydraulic unit to be applied to a power apparatus which produces power by utilizing a hydraulic pressure generated by a hydraulic pump (7). The hydraulic pump (7) has a pump main part (9a) and a rotary shaft (10) which protrudes from both the sides of the pump main part (9a) and is driven to rotate in a predetermined direction. Unidirectional clutches (15 and 16) are linked with both the ends (11 and 12) of the rotary shaft. One (15) of the unidirectional clutches is linked with an engine (13) and the other (16) is linked with an electric motor (14). At the time of low speed traveling, the hydraulic pump (7) is driven by the motor (14) only. At the time of high speed traveling, the hydraulic pump (7) is driven by the engine (13) only.</p> |
