The technical solution adopted for the present invention to solve the technical problems is：In shell, two impellers are separately mounted to respectively
From impeller axle on, impeller axle is arranged on shell through bearing, and the blade of impeller or impeller is connected with SFC, two leaves
Wheel submergence is in a fluid.With the power input outside impeller connection impeller axle reception, (its impeller hereinafter referred to as inputs impeller, its leaf
Wheel shaft hereinafter referred to as input shaft).Impeller axle output power, (its impeller hereinafter referred to as output impeller, its impeller axle are connected with impeller
Hereinafter referred to as output shaft).Using fluid (its fluid is once referred to as power transmission body) between transmission input impeller and output impeller
Power.Hereinafter the inclusion input shaft and the output shaft that include inputting impeller and output impeller, only claim impeller axle of impeller are only claimed.
Described impeller includes axial wheel, centrifugal impeller and radial impeller, and it is mainly made up of blade, wheel disc, the leaf of following impeller
Piece is referred to as blade, and the wheel disc of impeller is referred to as wheel disc.The blade of impeller is arranged on its wheel disc activity, but its blade can only be
Activity in the range of setting.Blade is connected with SFC, and to SFC instruction action, its SFC just can be controlled
Make the activity of connected impeller or its blade.This variator is can arbitrarily change area or the blade angle of front side of vane
Degree, to realize the rotating ratio between the input impeller of this variator and output impeller and torque ratio, can be continuously and arbitrarily variable
Function, described blade angle is the angle of its leaf angle.Movable on wheel disc with blade, support its blade working
Face area or blade angle variable, support activity and the positioning of its blade with the SFC that blade is connected, with blade
Controller receives the power of gear-shift command action and its instruction action.Described blade can on its wheel disc activity it is possible to understand that
Become impeller on blade be can activity or have in impeller can activity blade.SFC includes gear bar seat, tooth
Wheel bar, master gear, blade gear, helicla flute sleeve, burial wheel disc, hydraulic press, hydraulic circuit pipe, bearing, SFC can
With the embodiment according to its variator, select gear bar seat, gear bar, master gear, blade gear, helicla flute sleeve, burial

This variator transmits the process of power, and input shaft have received the power of outside and rotates, and installs on this input shaft
Input impeller also with rotation, propulsion power transmission body is moved by the rotation inputting impeller to output impeller end, the moving of movement
Power transmission body will force output impeller to rotate, the power transmission body after output impeller, be back to input leaf through circulation canal
Wheel end, repetitive cycling.
Front side of vane of the present invention refers to：The power that impeller can be rotated passes to power transmission body, and energy
Make power transmit the acting surface of the blade of body movement, or the blade that the conversion of motion of fluid can be become this impeller rotary motion acts on
Face, this blade acting surface hereinafter referred to as blade face.
Described leaf angle can be two kinds of forms, and the first participates in the blade being formed with axial line or axial radii line
Angle, its two be with power transmit body movement track participate in formation leaf angle.
In axial wheel, with a blade blade face, two points (two point equal with its impeller axle vertical dimension
Hereafter referred to collectively as blade face basic point), there is more than 0.1 millimeter of distance between two points, the line hereinafter referred to as leaf between two points
Piece baseline.The axial line that can intersect with blade baseline, hereinafter referred to as axle parallel lines, described axial line is the axial direction of its impeller axle
Line, its axial line is parallel with impeller axle.The angle that blade baseline is formed after being intersected with axle parallel lines, its angle is described,
Participate in the leaf angle being formed with axial line or axial radii line.
In centrifugal impeller or radial impeller, axis centered on its impeller axle, the cross section of its center axis, it is transversal
Face compared to this impeller blade, on a blade blade face in its cross section, unequal with its impeller axle vertical dimension two
Point (two point is hereafter referred to collectively as blade face basic point), has more than 0.1 millimeter of distance, the line between two points between two points
Hereinafter referred to as blade baseline.The angle that blade baseline is formed after being intersected with its impeller axle radial alignment, its angle is described,
Participate in the leaf angle being formed with axial line or axial radii line, the length of described impeller axle radial alignment is prolonged as needed
Long, until can intersect and produce angle with described blade baseline.
In this transmission duty, by the power transmission body of movement between input impeller and output impeller, its movement
Track hereinafter referred to as power track, is formed its power track and can be understood as being passed with the power in a cubic unit space
Defeated body or transmit the mobile of certain molecule of body with power and formed, transmits body molecule and its molecule with a movement with power below
Form mapping and explanation.In impeller, the angle of formation after blade baseline and power intersection of locus, when its power track is not straight
During line, then take the straight line isometric with blade baseline, its straight line hereinafter referred to as track straight line, blade baseline and power intersection of locus
