Invention content：
The present invention relates to a kind of novel hydraulic torque converter, structure includes mainly：Pump impeller BL, driven disc CP, coupling differential
Device YO, wherein the input shaft of the pump impeller BL and the novel hydraulic torque converter are connected, surfaces of revolution view is circle, axial plane
Sectional view is semicircular arc, and has radial strut blade；
The output shaft of the driven disc CP and the novel hydraulic torque converter are connected, and surfaces of revolution view is circle, axis
Face sectional view is semicircular arc, and has radial strut blade, and work is full of between pump impeller BL and driven disc CP and between blade
Liquid；
The coupling differential mechanism YO is made of annulus cylinder body GT, spiral rib plate LJ, rotating disc P and couple rotor C, wherein round
Ring cylinder body GT is a cylinder body for having annular cavity, and the axial plane sectional view of annular cavity is round；The spiral rib plate LJ
It in the annular cavity, is distributed along arc-shaped surface, and combine as a whole with the annulus cylinder body GT, forms annulus duct cylinder
Body；Annulus duct cylinder body is provided with cylinder body annular groove along annular cavity, and the rotating disc P is located in cylinder body annular groove；
The couple rotor C is mounted on rotating disc P, is located in annular cavity, the radial outer edge and circle of couple rotor C
Toroidal cavity inner surface is in contact, and pivot center is vertical with the pivot center of rotating disc P, and with the annulus axle of annular cavity
Line is tangent；
The couple rotor C is provided with coupling slot along radial direction, and spiral rib plate LJ can pass through coupling slot, work as couple rotor
When C and rotating disc P and annulus duct cylinder body relatively rotate, the promotion that slidably engages of spiral rib plate LJ and coupling slot couple turn
Sub- C surrounds own rotation axis rotation；
The spiral rib plate LJ along the annular cavity arc-shaped surface be distributed so that couple rotor C with rotating disc P with
Annulus duct cylinder body generates relative rotation, and when with uniform rotational speed, cunnings of the couple rotor C because of coupling slot and spiral rib plate LJ
It moves engagement and surrounds own rotation axis with uniform rotating speed rotation；
The initiating terminal of the spiral rib plate LJ is located at the side of rotating disc P, and starts to slide with the coupling slot of couple rotor C
Engagement, with the relative rotation between rotating disc P and annulus duct cylinder body, thrusts of the couple rotor C in spiral rib plate LJ
Lower rotation reaches the clearing end of the spiral rib plate LJ of the other sides rotating disc P, then spiral rib plate LJ is disengaged from coupling slot, and
It is rotated further, returns to the initiating terminal side of spiral rib plate LJ, and start next slidably engage；
Position of the annulus duct cylinder body near the initiating terminal and clearing end of the both sides rotating disc P spiral rib plate LJ, is opened
There is working solution entrance, when rotating disc P and couple rotor C produces relative rotation with annulus duct cylinder body, working solution is by going out
Entrance flows into and out coupling differential mechanism YO；
Driven disc CP installations opposite with the pump impeller BL, the coupling differential mechanism YO are located at pump impeller BL and driven disc
It is separated into higher-pressure region and low-pressure area between CP and by the outer edge area between pump impeller BL and driven disc CP.
Working solution, the annulus duct cylinder body and rotating disc of the coupling differential mechanism YO are full of in the novel hydraulic torque converter
P is linked with pump impeller BL or driven disc CP respectively, and the working solution entrance of the both sides rotating disc P is located at higher-pressure region and low pressure
Area, pump impeller BL is rotated by the pressure official post driven disc CP of higher-pressure region and low-pressure area, to drive output shaft output torque.
When pump impeller BL is driven by the engine rotation, working solution by the blade of pump impeller BL with rotation, and centrifugation force effect
Under, flowed from the inner edge of blade to outer rim, working solution is got rid of by pump impeller BL to outer rim, pump impeller BL outer rims with couple differential mechanism YO
Between region formed high-pressure area.
The outer rim of driven disc CP is less than the rotation half of high-pressure area with the region between differential mechanism YO, the radius of gyration is coupled
Diameter, therefore it is referred to as low-pressure area.The working solution entrance of the sides rotating disc P of coupling differential mechanism YO is located at higher-pressure region, rotating disc P
The working solution entrance of the other side is located at low-pressure area.
At the initial stage of starting, the rotating speed of driven disc CP is much smaller than the rotating speed of pump impeller BL, therefore, the annulus cylinder of coupling differential mechanism YO
Relative rotation speed between body GT and couple rotor C is very big, and a large amount of working solution will overcome the pressure between higher-pressure region and low-pressure area
Difference, after being discharged from low-pressure area to higher-pressure region, the recirculation zone inner edge area circulating reflux between pump impeller BL and driven disc CP, because
This, the speed discrepancy between driven disc CP and pump impeller BL is bigger, and the torque suffered by driven disc CP is bigger, and what is provided to output shaft turns
Square is also bigger.
It is continuously improved with the rotating speed of driven disc CP, flows through what coupling differential mechanism YO was discharged to higher-pressure region again from low-pressure area
Working solution is constantly reduced, and until driven disc CP and pump impeller BL are synchronized, then working solution stops flowing, and the pressure of higher-pressure region at this time
Power is still more than the pressure of low-pressure area, when this pressure difference is enough to make working solution to overcome the resistance of coupling differential mechanism YO, and passes through
When coupling differential mechanism YO is flowed to low-pressure area, then the rotating speed of driven disc CP will be greater than the rotating speed of pump impeller BL, until turning for output shaft
Speed, which increases to suffered resistance and constantly increases, makes the pressure difference of itself and higher-pressure region and low-pressure area balance each other, then the rotating speed of driven disc CP
It will no longer increase, this is the biggest advantage of the present invention compared with prior art, when running at a low speed, is capable of providing big torsion
Square when running at high speed, is capable of providing big rotating speed.
Working solution is full of between pump impeller BL and driven disc CP, the area that working solution flows between pump impeller BL and driven disc CP
The blade of worm gear WL, the worm gear WL is installed with rotation direction in domain into angle so that when worm gear WL rotations, worm gear WL blades
Treatment fluid flow is pushed to the directions pump impeller BL.
Worm gear WL is directly coupled with pump impeller BL, or is coupled with pump impeller BL by planetary gear mechanism XC, the planet tooth
Wheel mechanism XC is made of sun gear T, gear ring R, planet carrier S and planetary gear u, and planetary gear u is installed on the planet of planet carrier S
It on gear shaft, is engaged with both gear ring R and sun gear T, planetary gear u can both surround planetary gear shaft rotation, can also be
Walking is around sun gear T revolution in gear ring R.Worm gear WL is coupled with sun gear T, and pump impeller BL is coupled with planet carrier S, and gear ring R is fixed.
The annulus duct cylinder body of coupling differential mechanism YO can both be coupled with pump impeller BL, can also be coupled with driven disc CP, phase
It is corresponding, be：Rotating disc P is coupled with driven disc CP or is coupled with pump impeller BL, the sides rotating disc P of coupling differential mechanism YO
Inlet and outlet are located at the regions pump impeller BL, that is, higher-pressure region, and the working solution inlet and outlet of the other sides rotating disc P are located at the areas driven disc CP
Domain, that is, low-pressure area.
It can be single spiral rib plate LJ to couple differential mechanism YO, can also be a plurality of spiral rib plate LJ, the blade of pump impeller BL
It can be that radial direction is linearly unfolded, can also be unfolded from inside to outside with curve form, the blade of driven disc CP can be half
Diameter direction is linearly unfolded, and can also be unfolded from inside to outside with curve form.
Couple rotor C can be monomer structure, can also be multi-disc composite structure.
No matter the novel hydraulic torque converter designed in this way starts initial stage driven disc CP due to the effect of worm gear WL blades
Slow-speed of revolution stage or later stage driven disc CP in the high rotating speed stage, worm gear WL all by working solution to the regions pump impeller BL push,
Which increases the pressure of higher-pressure region, reduce the pressure of low-pressure area, and driven disc CP will be by exporting axial gearbox transmission
Higher torque, especially worm gear WL are combined by planetary gear mechanism XC and pump impeller BL, and the rotating speed of worm gear WL will compare pump impeller
The rotating speed of BL is high, increases the pressure difference of higher-pressure region and low-pressure area, high speed when driving, the rotating speed for making driven disc CP is being pumped
The effect of speedup is more preferable on the basis of wheel BL rotating speeds.
When pump impeller BL and driven disc CP uses the blade of curve form, the pressure of higher-pressure region and low-pressure area is equally increased
Difference, when rotated, pump impeller BL curve of the blade is applied with one from the inner edges pump impeller BL to pump impeller BL outer rims to pump impeller BL to working solution
Pushing force, this will improve the pressure of higher-pressure region, while driven disc CP uses the song opposite with pump impeller BL blade curve expansion directions
Line blade, when rotated, blade is applied with a pushing force from outer rim to inner edge to driven disc CP to working solution, this will offset or
Partial offset centrifugal force and the pressure for reducing low-pressure area, it can thus be seen that high speed when driving, driven disc CP speedups
Effect is equally apparent.

If annulus cylinder body GT is linked with pump impeller BL, rotating disc P is linked with driven disc CP, then when spiral shell as shown in the figure
When rotation gusset LJ turns left, then pump impeller BL is located at the underside area of annulus cylinder body GT, and driven disc CP is located at annulus cylinder body GT's
Upper-side area.At the initial stage of starting, output shaft speed is low less than drive shaft speed, that is, the speed of rotating disc P and couple rotor C
In the speed of annulus cylinder body GT and spiral rib plate LJ.Working solution is sucked from the entrance in the regions driven disc CP, in the regions pump impeller BL
Entrance discharge, and the speed of pump impeller BL is far above the speed of driven disc CP, that is, the regions pump impeller BL entrances at this time
Pressure is more than the pressure of the regions driven disc CP entrance, the movement resistance which increases couple rotor C in annulus cylinder body GT
Power, pump impeller BL and the speed difference of driven disc CP are bigger, then couple rotor C resistances of relative motion in annulus cylinder body GT are got over
Greatly, the torque that output shaft provides is bigger.

In pump impeller BL outer rims and the radius of gyration for coupling the region between differential mechanism YO, therefore, pump impeller BL is produced when rotating at high speed
The low pressure zone of the high-pressure zone and driven disc CP outer edge areas of pump impeller BL outer edge areas.
At the initial stage of starting, because the rotating speed of driven disc CP is much smaller than the rotating speed of pump impeller BL, therefore, a large amount of working solution is coupled
Differential mechanism YO pushes the regions pump impeller BL to higher-pressure region from the regions driven disc CP of low-pressure area, when between higher-pressure region and low-pressure area
Pressure official post driven disc CP rotating speeds are stepped up and when close to the rotating speeds of pump impeller BL, then working solution is from the coupled differential mechanism of low-pressure area
The flow of YO to higher-pressure region gradually reduce stopping flowing, if the pressure difference between higher-pressure region and low-pressure area be enough to overcome it is driven
The resistance that disk CP is subjected to, then the coupled differential mechanism YO of working solution flow to low-pressure area from higher-pressure region, the rotating speed of driven disc CP at this time
The rotating speed of pump impeller BL will be gradually higher than, until the rotating speed of output shaft incrementally increases, resistance is made constantly to be increased to and higher-pressure region and low
