摘要： A hydraulic transmission apparatus having at least one declutchable hydraulic motor having radial pistons and connected via two motor ducts, and a casing duct connected to the inside of the casing. The apparatus further has clutching means that, in order to perform the clutching of the motor, are suitable for bringing a first one of the motor ducts to a “clutching” first pressure that is higher than the pressure in the casing while also making it possible to remove fluid via the casing duct. Disposed on the casing duct, the apparatus further has means for limiting the flow of fluid in said casing duct, in a manner such as to cause the pressure inside the casing to increase during the clutching operation. This apparatus enables clutching to take place gently.

摘要： A bi-directional pump connected to a motor by a pair of supply/discharge lines; a regulator changes the bi-directional pump tilting angle; and a controller controls the regulator based on a turning signal outputted from a turning operation valve. At the turning acceleration, at which the signal increases, the controller calculates a motor flow rate passing through the motor and an instruction flow rate determined based on the turning signal. If the instruction flow rate is greater than a reference flow rate obtained by adding a predetermined value to the motor flow rate, the controller controls the regulator so the bi-directional pump tilting angle is adjusted to a tilting angle realizing the reference flow rate. If the instruction flow rate is not greater than the reference flow rate, the controller controls the regulator so the bi-directional pump tilting angle is adjusted to a tilting angle realizing the instruction flow rate.

摘要： A hydraulic transmission comprising a variable displacement pump and motor, at least one having cylinders having valves which are controllable on each cycle of cylinder working volume to determine the net displacement of working fluid by the cylinder. The transmission has a valve control module which determines a displacement of the pump and the motor by specifying a displacement demand. The pump and/or motor valve control module determine the frequency of intensity peaks in the frequency spectrum of the pattern of cylinders carrying out active and inactive cycles of cylinder working volume using a first procedure and, if these will fall within disallowed frequency bands including the resonant frequency of components with which the transmission is in mechanical communication, the displacement demand, or another input, is periodically modified to suppress generation of those frequencies. The hydraulic transmission is useful for example in a wind turbine generator, or a vehicle.

摘要： A variable capacity hydraulic pump (10) drives a concrete agitating drum (1) via a hydraulic motor (81). A hydraulic actuator (14) regulates a discharge flow rate of the hydraulic pump (10) depending on an actuator driving pressure. A load sensing valve (40) generates the actuator driving pressure by reducing a discharge pressure of the hydraulic pump (10) according to a differential pressure between the discharge pressure and a load pressure acting on the hydraulic motor (81). A shut-off valve (20) shuts off supply of the pressurized oil discharged from the hydraulic pump (10) to the hydraulic motor (81). Due to this action, when the differential pressure increases beyond a predetermined differential pressure, an unload valve (30) drains the discharged oil, thereby preventing the hydraulic pump (10) from generating noise due to an excessive increase in the discharge pressure.

摘要： A hydrostatic transmission, comprising a housing, an interior space of the housing serving as a fluid sump; a center section disposed in the housing so as to be submerged In the fluid sump; a hydraulic pump mounted on the center section in the housing: a hydraulic motor mounted on the center section in the housing, and a pair of first and second fluid passages formed within the center section so as to fluidly connect the hydraulic pump with the hydraulic motor. The second fluid passage has an upwardly slant opening toward the fluid sump. A draining device including a relief valve is provided in the opening of the second fluid passage. When hydraulic pressure in the second fluid passage is not more than a predetermined value but not less than that in the first fluid passage, the relief valve is opened so as to drain fluid from the second fluid passage to the fluid sump, thereby keeping the hydrostatic transmission in neutral. When hydraulic pressure in the second fluid passage is more than the predetermined value or less than that in the first fluid passage, the relief valve is closed so as to shut out fluid in the second fluid passage from the fluid sump. The draining device comprises a ball check valve which closes the relief valve by its dead weight when the hydraulic pressure in the second fluid passage is less than the first fluid passage.

摘要： A hydrostatic transmission comprises a housing whose interior space serves as a fluid sump, a pair of first and second fluid passages disposed in the housing, the pair of first and second fluid passages interposed between the hydraulic pump and the hydraulic motor so as to constitute a closed fluid circuit of an HST. A charge fluid passage is disposed in the housing so as to be connected with each of the first and second fluid passages for supplying fluid from the fluid sump into the closed fluid circuit. A drain fluid passage including an orifice is disposed in the housing so as to be connected with at least one of the first and second fluid passages so that, when hydraulic pressure in the at least one of the first and second fluid passages is increased beyond its neutral level, excessive fluid in the at least one of the first and second fluid passages is drained through the drain fluid passage to the fluid sump, thereby expanding the neutral zone of the HST. The charge fluid passage and the drain fluid passage are open to the fluid sump while the charge fluid passage and the drain fluid passage being separated from each other, thereby preventing the closed fluid circuit from overheating. If a center section, which has a first and second side ends opposite to each other and forms the first and second fluid passages therein, is disposed in the housing, an opening of said charge fluid passage in communication with said fluid sump is disposed toward said first side end of said center section, and an opening of said drain fluid passage in communication with said fluid sump is disposed toward said second side end of said center section.

The hydraulic pressure is controlled by changing the inclination angle of a movable swash plate. The driving conditions which prompt the control system may include: (1) A signal voltage of a throttle sensor indicates the throttle opening is lower than a first threshold value; (2) A vehicle speed is over a second threshold value; (3) An acceleration is over a third threshold value; (4) An engine speed is below a fourth threshold value; and (5) Conditions (1) through (4) last for a predetermined period of time.
