Description
A kind of permanent torque type hydrostatic pressure torque-converters that is connected with float element in the pure mechanical planet seat (row) with the input shaft of external parts pump and the pure mechanical planet row's of rear portion band permanent torque type hydrostatic pressure mechanical torque converter thereof; The input shaft of external parts pump is connected with float element in machine, the component coenosarc of liquid planetary static pressure motor and provides the constant power type hydrostatic pressure torque-converters of high pressure oil and the hydrostatic pressure mechanical torque converter of the pure mechanical planet seat of rear portion band (row) thereof by pump to machine, component coenosarc of liquid motor; The input shaft of the pump of machine, component coenosarc of liquid planet seat (row) formula is connected with float element in machine, component coenosarc of liquid planet seat (row) the formula motor, and the planetary mechanical torque converter of machine, component coenosarc of liquid of the pure mechanical planet seat of constant power type machine, component coenosarc of liquid formula static pressure torque converter and rear portion band thereof (row) of high pressure oil is provided to machine, component coenosarc of liquid motor by pump; Machine, the input shaft and the machine of component coenosarc of liquid planet seat (row) formula pump, float element in component coenosarc of liquid planet seat (row) the formula motor is connected, the high-pressure oil passage of pump is only made throttle grverning, the motor in planet seat (row) does not provide the machine of high pressure oil, the permanent torque type static pressure torque converter of planetary permanent torque type static pressure torque converter of component coenosarc of liquid and the pure mechanical planet seat of rear portion band (row) thereof is characterized by: the oil hydraulic pump by various external parts (contains vane pump, profile of tooth is the interior external gear pump of involute and linear conjugated tooth, Gerotor pump, plunger pump, screw pump, ball piston pump) input shaft and all kinds have in the planet seat (row) of pure machinery of float element and are that the circumferential float element of circumferential movement braking force is connected with the counterpressure of said pump, circumferentially float element can be a sun gear, ring gear, planet carrier, profile of tooth in the planet seat (row) can be an involute, cycloid, circle-arc tooth, linear conjugated tooth, in being connected of said pump and float element can be direct, indirectly, vertically, connect abreast, also can multi-plate friction clutch that links to each other with static element in parallel, and lean on the flow control valve of pump to carry out Flow-rate adjustment, realize the infinite variable speed hydrostatic pressure torque-converters and the hydrostatic pressure mechanical torque converter thereof of permanent torque type.Mechanical part in the hydrostatic pressure mechanical torque converter can be the planet seat (row) of pure internal tooth engagement, can be other forms of planet seats (row) such as NGW, also can be the planet wheel seat and the parallel axes external tooth meshing part of parallel axes.
The input shaft and the machine of above-mentioned various external parts oil hydraulic pumps (the pump structure type is the same), circumferential float element in all kinds of planet pumps (motor) seats (row) of component coenosarc of liquid is connected, counterpressure with external parts pump is the circumferential movement braking force of circumferential float element, circumferentially float element can be a sun gear, planet carrier, ring gear, profile of tooth can be an involute, cycloid, circle-arc tooth, linear conjugated tooth, in being connected of said pump and float element can be direct, indirectly, vertically, connect abreast, also can multi-plate friction clutch that links to each other with static element in parallel, rely on external parts delivery side of pump flow control valve to carry out Flow-rate adjustment realizing stepless change, and with the hydraulic oil of pump to machine, constant power type hydrostatic pressure torque-converters and hydrostatic pressure mechanical torque converter thereof that the planet motor fuel feeding of component coenosarc of liquid forms.With the back pressure brake of external parts pump hydraulic oil, the circumferential float element in the component coenosarc of liquid motor, carry out throttle grverning, its hydraulic oil is not to the constant force square parts of machine, component coenosarc of liquid motor fuel feeding.Mechanical part in the hydrostatic pressure mechanical torque converter can be pure interior engagement planet seat (row), can be other forms of planet seats (row) such as NGW, also can be parallel axes planet wheel seat and parallel axes external tooth meshing part.
Fluid coupling, fluid torque converter are meant that the dynamic pressure with liquid is a power in the prior art, respectively by pump impeller and worm gear; The parts that pump impeller, guide wheel and worm gear are formed, (seeing Xu Hao for details edits and all kinds of planet seats of fluid torque converter rear portion band (row) parts system is referred to as the hydraulic machine torque-converters; Chapter 1 was to chapter 4 during the mechanical design handbook the 5th that China Machine Press publishes December nineteen ninety-five was rolled up the 39th piece).
The present invention seeks to the static pressure torque converter little with volume, that efficient is high and replace big, inefficient fluid torque converter of volume of the prior art and variable speed fluid coupling.In the prior art, fluid torque converter is the kinetic pressure transmitting torque with fluid power, the only about 5～8kg/cm of its pressure maximum
2So when its transmission power often only reached 20% left and right sides of original machine power, being about to pump impeller and worm gear locking was that one (sees Xu Hao chief editor mechanical design handbook the 5th volume table 39-3-1 for details; Product type, specification, the technical parameter of the centrifugal worm gear fluid torque converter of single-phase single-grade).
The startup shock-absorbing capacity of the dry type coupling that the medium and heavy vehicle of prior art adopts is very little, but not the speed sliding difference of variable speed fluid coupling only is about 3%, so its transmission device often needs 7～9 gears just can reach maximum travel speed.
Principle of the present invention is: can utilize the hydraulic pressure back pressure of pump impeller that float element braking and promotion output element are advanced when starting when the input shaft of the float element of planet seat and external parts oil hydraulic pump links, and the speed of float element can the mat pump impeller fluid flow regulate and realize the stepless change operation, and for the planet wheel seat with machine, component coenosarc of liquid (planet motor), then the high pressure oil of oil hydraulic pump can be provided with driving the planet motor running again, the operation of the constant output characteristic of realization machine, the stack of liquid element moment makes its transmission efficiency higher.Not to machine, component coenosarc of liquid motor fuel feeding, only the circumferential float element in planetary then forms constant force square parts with the back pressure braking as the pressure oil of said pump.
Implementing optimum scheme of the present invention is: link with the float element in the planetary oil hydraulic motor of the input shaft of various oil hydraulic pumps and machine, component coenosarc of liquid, and the high pressure oil of external pump can be to the motor oil pocket fuel feeding of planet seat, so that realize permanent power operation.
