複合モード油圧変速装置
Document Type and Number:
Japanese Patent JP3596992
Kind Code:
B2
Abstract:
A combined mode hydrostatic transmission comprises a differential hydraulic motor and a variable capacity hydraulic pump for supplying this motor with pressurized oil. The differential hydraulic motor comprises a swash plate connected to an output shaft and a cylinder block joined to an input shaft. Further provided are a brake which selectively brakes the rotation of the cylinder block and a clutch which selectively interrupts the input rotation to the cylinder block. When the brake is operated and fluid is supplied from the variable capacity hydraulic pump with the clutch disengaged, the differential hydraulic motor functions in a HST mode. When the brake is released, the clutch is connected and fluid is supplied from the variable capacity hydraulic pump, the differential hydraulic motor functions in a HMT mode.
