Description
Technical field
The present invention relates to mechanical transmission fields, more particularly to a kind of free wheel construction of loading machine torque-converters.
Background technology
Fluid torque-converter is the Hydraulic Machinery for being widely used in automobile, fork truck, engineering machinery and defence equipment.Fluid power
Torque-converters uses fluid as working media, not only delivers moment of torsion but also increased moment of torsion with multiplying power, realizes engine soft
Start, the tractive force and speed of main frame adapt to the change of load and road automatically.As shown in figure 1, traditional torque-converters it is main by
Pump impeller 1 ', turbine 2 ', the element of guide wheel 3 ' three composition, the flywheel of engine are coupled by elastic plate, the gear-box of load with
The axle of turbine 2 ' is connected, and guide wheel 3 ' is integral plugged on wheel stand 4 '.
The pump impeller 1 ' of fluid torque-converter is driven to rotate together with therewith when engine is operated, the hydraulic oil in pump impeller 1 ' is in centrifugation
In the presence of power, first turbine 21 ', two-stage turbine 22 ' are rushed at by the blade outer rim of pump impeller 1 ', and along the blade flow of turbine 2 ' to guide wheel
3 ', then through the vane inside edge of guide wheel 3 ', form the liquid stream of circulation.The effect of guide wheel 3 ' is to change the output torque on turbine 2 '.By
Still have sizable impulsive force in the hydraulic oil that guide wheel 3 ' is flowed to from the blade lower edge of turbine 2 ', if by pump impeller 1 ', turbine 2 ' and
The blade design of guide wheel 3 ' is into certain shape and angle, it is possible to which the output that turbine 2 ' is improved using above-mentioned impulsive force is turned round
Square.When vehicle is before starting, the rotating speed of turbine 2 ' is 0, and engine drives pump impeller 1 ' to rotate by elastic plate, and hydraulic oil is produced
A raw size is the moment of torsion of Mp, and the moment of torsion is the input torque of fluid torque-converter.Promotion of the hydraulic oil in the blade of pump impeller 1 '
Under, with certain speed, the blade at the upper limb of turbine 2 ' is rushed at, impulsive torque is produced to turbine 2 ', the moment of torsion is fluid power change
The output torque of square device.The now transfixion of turbine 2 ', the hydraulic oil for rushing at turbine 2 ' flows to the lower edge of turbine 2 ' along blade, in whirlpool
2 ' lower edges of wheel rush at guide wheel 3 ', to guide wheel 3 ' with certain speed along with the lower edge of turbine 2 ' exit blade identical direction
Also an impact moment is produced, and pump impeller 1 ' is flowed back to along the fixed blade of guide wheel 3 '.When hydraulic oil is to turbine 2 ' and guide wheel
During 3 ' generation impulsive torque, turbine 2 ' and guide wheel 3 ' are also equal in magnitude with impulsive torque, in opposite direction to hydraulic oil generation one
Reaction turn round Mt and Ms;, the wherein direction of Mt is in opposite direction with Mp, and the direction of Ms is identical with the direction of Mp.According to liquid
Force feed stress balance principle, can obtain： Mt=Mp+Ms.Reaction due to turbine 2 ' to hydraulic oil, moment of torsion Mt is with hydraulic oil to whirlpool
The impulsive torque of wheel 2 '（That is the output torque of torque-converters）It is equal in magnitude, in the opposite direction, thus, it can be known that the output of fluid torque-converter
Moment of torsion is numerically equal to the reaction torque sum of input torque and guide wheel 3 ' to hydraulic oil.Obvious this moment of torsion is greater than defeated
Entering moment of torsion, i.e. fluid torque-converter has the effect of increase moment of torsion.The part of fluid torque-converter output torque increase is to be fixed not
The opplied moment of hydraulic oil of the dynamic guide wheel 3 ' to circulating, its numerical value depends not only on the liquid that guide wheel 3 ' is rushed at by turbine 2 '
Flow velocity degree, also depends on the angle between liquid flow path direction and the blade of guide wheel 3 '.When flow stream velocity is constant, the folder of blade and liquid stream
Angle is bigger, and the moment of reaction is also bigger, and the increasing torsion effect of fluid torque-converter is also just bigger.Due to guide wheel 3 ' be it is fixed,
When vehicle in the presence of fluid torque-converter output torque after starting to walk, the turbine 2 ' being connected with driving wheel also begins to rotate, its
Rotating speed is continuously increased with the acceleration of vehicle.At this moment the hydraulic oil of turbine 2 ' is rushed at by pump impeller 1 ' except along the blade flow of turbine 2 '
Outside dynamic, also together to be rotated with turbine 2 ' so that the direction of the hydraulic oil of guide wheel 3 ' is rushed at by the lower edge of turbine 2 ' exit
Change, no longer the direction with the exit of turbine 2 ' blade is identical, but the direction deflection forward rotated along turbine 2 '
One angle, makes the angle rushed between the liquid flow path direction of guide wheel 3 ' and the blade of guide wheel 3 ' diminish, suffered on guide wheel 3 ' to rush
Hit torque also to reduce, the increasing torsion effect of fluid torque-converter also reduces therewith.Speed is higher, and the rotating speed of turbine 2 ' is bigger, rushes at guide wheel
3 ' hydraulic oil direction is just smaller with the angle of the blade of guide wheel 3 ', and the increasing torsion effect of fluid torque-converter is also smaller；Conversely, speed heals
Low, the increasing torsion effect of fluid torque-converter is just bigger.Therefore, compared with fluid coupling, fluid torque-converter is in low vehicle speeds
When have larger output torque, in vehicle start, when going up a slope or running into larger running resistance, driving wheel can be made to obtain larger drive
Kinetic moment.When the rotating speed of turbine 2 ' is when the raising of speed increases to a certain numerical value, rush at guide wheel 3 ' hydraulic oil direction with
Angle between the blade of guide wheel 3 ' is reduced to 0, and at this moment guide wheel 3 ' will not receive the percussion of hydraulic oil, and fluid torque-converter loses increasing
Torsion effect, its output torque is equal to input torque；If the rotating speed of turbine 2 ' further increases, rush at the hydraulic oil direction of guide wheel 3 ' after
It is continuous oblique forward, hydraulic oil is impacted at the back side of the blade of guide wheel 3 ', at this moment side of the guide wheel 3 ' to the reaction torque Ms of hydraulic oil
To with pump impeller 1 ' to the in opposite direction of hydraulic oil moment of torsion Mp, so output torque on turbine 2 ' is the difference between the two, i.e. Mt=Mp-
Ms, the output torque of fluid torque-converter is smaller than input torque on the contrary, and its transmission efficiency also reduces therewith.Therefore it is solid using guide wheel 3 '
Fixed fluid torque-converter, when the rotating speed of turbine 2 ' is relatively low, the transmission efficiency of fluid torque-converter is imitated higher than the transmission of fluid coupling
Rate；When the rotating speed of turbine 2 ' increases to a certain numerical value, the transmission efficiency of fluid torque-converter is equal to the transmission effect of fluid coupling
Rate；After the rotating speed of turbine 2 ' continues to increase, the transmission efficiency of fluid torque-converter is by less than the transmission efficiency of fluid coupling, and its is defeated
Go out moment of torsion also to decline therewith；In order to overcome turbine 2 ' when high speed rotates, first turbine 21 ', two-stage turbine 22 ' are produced to it
Reaction force causes its transmission efficiency to reduce, and has the generation of this case then.
