| 20080271939 | Pump System And Axle-Driving System - A pump system includes a housing, an input shaft, a pump shaft; a hydraulic pump body, a PTO shaft, a power transmission gear train, and a PTO clutch mechanism. The housing has a narrow gear accommodating space surrounding a region including a mesh point between the first and second transmission gears of the power transmission gear train, a PTO clutch accommodating space which surrounds the PTO clutch mechanism and which is fluidly communicated with the gear accommodating space, and a pair of first and second suction/discharge ports which communicate the internal space of the housing with an outside of the housing. The first suction/discharge port is arranged within the gear accommodating space so as to be positioned in an opposite side to the PTO clutch accommodating space with the mesh point between the first and second transmission gears interposed therebetween. | 11-06-2008 |
| 20080314675 | HYDRAULIC WHEEL-DRIVE WORKING VEHICLE - A hydraulic wheel-drive working vehicle according to the present invention makes it possible to change a driving state by a driving-mode switching valve between a right-left differential-lock driving state in which a pair of driving wheels are driven in an independent manner to each other with hydraulic fluid discharged from a hydraulic pump and having respective amounts defined by a flow dividing/combining mechanism and a right-left differential driving state in which the pair of left and right driving wheels are driven in a hydraulically differential manner to each other, and also to supply the hydraulic fluid from the hydraulic pump to the pair of hydraulic motors without being subjected to fluid load of the flow dividing/combining mechanism at the right-left differential driving state, thereby enhancing transmission efficiency at the right-left differential driving state. | 12-25-2008 |
| 20090211834 | Hydraulic Four-Wheel-Drive Working Vehicle - A hydraulic four-wheel-drive working vehicle includes a hydraulic pump unit having a hydraulic pump main body of a variable displacement type, a pair of left and right first motor devices driving a left and right first driving wheels, and a pair of left and right second motor devices driving a left and right second driving wheels, wherein each of the pair of first motor devices and the pair of second motor devices includes a hydraulic motor main body forming an HST in cooperation with the hydraulic pump main body, a motor volume adjusting mechanism, and a hydraulic actuating mechanism that operates the motor volume adjusting mechanism, and the hydraulic actuating mechanisms in the pair of first motor devices and the pair of second motor devices are operated and controlled with use of hydraulic fluid from a single hydraulic pressure source. | 08-27-2009 |
| 20090301076 | Vehicle Transaxle System - A vehicle transaxle system includes a pair of right and left transaxle units equipped on a vehicle. The right transaxle unit supports a single right axle, and the left transaxle unit supports a single left axle. A variable displacement hydraulic pump is disposed in each of the right and left transaxle units so as to be driven by power from a prime mover of the vehicle. A variable displacement hydraulic motor is disposed in each of the right and left transaxle units and is fluidly connected to the corresponding hydraulic pump so as to drive the corresponding right or left axle. A movable motor displacement control member is provided in each of the transaxle unit so as to be moved to change the displacement of the corresponding hydraulic motor. An interlocking connection means is connected to both the movable motor displacement control members of the respective hydraulic motors. The vehicle is provided with a first manipulator for changing displacements of the hydraulic pumps, and is provided with a second manipulator for operating the interlocking connection means. The interlocking connection means is operated by operating the second manipulator so as to synchronously move both the movable motor displacement control members. | 12-10-2009 |
| 20110088545 | Hydraulic Actuator Unit - In the hydraulic actuator unit according to the present invention, a first electric motor assembly formed by mounting one of a pair of electric motors to one of a pair of electric motor covers is detachably mounted to a pump case so as to rotate a first control shaft around its axis line, and a second electric motor assembly formed by mounting the other one of the pair of electric motors to the other one of the pair of electric motor covers is detachably mounted to the pump case so as to rotate a second control shaft around its axis line.
