The working principle of the invention realizes that rotary inertia reflects used under object rotary state using rotary inertia
Property：The angular speed of the big object of rotary inertia is more difficult to change.In the case where input torque and mass conservation, with rotary body
Radius increase, the rotary inertia of rotary body will increase, and the rotation speed of rotary body is smaller, and the angular speed of rotary body is more at this time
It is difficult to change；In the case where input torque and mass conservation, with the reduction of the radius of rotary body, the rotary inertia of rotary body
It will reduce, the rotation speed of rotary body is larger, and the angular speed of rotary body is easy to change at this time.
Propeller shaft sleeve is fixed by the first L-type plate in the present invention, and propeller shaft sleeve can be rotated around the axis of oneself；Output
Axis is fixed by total fixed plate, and output shaft can be rotated around the axis of oneself；Transmission gear drives the first rotation through propeller shaft sleeve
Change set rotation；Fixed ring is fixed by the first L-type plate, disk be fixed ring fix and disk can around oneself axis revolve
Turn.Driving motor drives driving gear rotation through the second axis；Reciprocating motor can drive reciprocating gear reciprocating rotary through first axle.
Reciprocating gear is meshed with the grinding tooth on disk, then the axis that reciprocating gear can drive disk to surround oneself is past
Multiple rotation.
The axis of output gear and the axis collinear of disk, the design that transition gear is meshed with output gear be, by
Be fixed on disk in transition gear by axis, during disk reciprocating rotary transition gear can around disk axis it is past
Physical pendulum is dynamic；Due to the axis of output gear and the axis collinear of disk, so transition gear is in the mistake for following disk reciprocally swinging
It can be meshed always with output gear in journey.
Transmission gear is respectively with transition gear and the effect that matches of driving gear：In the process of disk reciprocating rotary
In, disk drives the driving gear reciprocally swinging on transition gear and driving motor；When disc rotary to driving gear and transmitting
When gear is meshed, driving gear band moves transmission gear rotation；It is mutually nibbled when disk is reversely rotated to transition gear with transmission gear
When conjunction, transmission gear drives transition gear rotation, and then transition gear drives output gear rotation.
The effect of gear regulator in the present invention is：It is adjusted according to the travel speed of new energy vehicle and is moved down on connecting plate
It is dynamic, and then connecting plate is moved up and down through the dynamic second rotating ring set of the first annulus to adjust the length of R, the rotation of such transmission gear
Speed will be changed, so that the output revolving speed of output gear also changes, the final row for cooperating driving motor driving new energy vehicle
It sails.
When the distance between first rotation ring set and the second rotation ring set are farthest, the hinge of first connecting rod and corresponding second connecting rod
The distance of axis of contact to slide bar is R, and the length of R is most short.By the first rotation ring set, two first connecting rods, two second
Connecting rod and the second rotation ring set constitute stored energy mechanism.
When speed changer needs work, driving motor drives driving gear high speed rotation through the second axis；When reciprocating motor passes through
When first axle drives reciprocating gear to rotate clockwise, reciprocating gear drives disc counter-clockwise rotation, and disk drives driving gear inverse
Hour hands are swung；When driving gear to engage with transmission gear, driving gear drives the first rotating ring through transmission gear, propeller shaft sleeve
Cover high speed rotation；First rotation ring set drives the second rotation ring set high speed rotation through first connecting rod, second connecting rod.
When reciprocating motor drives reciprocating gear to rotate counterclockwise through first axle, reciprocating gear drives disk to revolve clockwise
Turn, disk drives driving gear clockwise oscillation, drives gear to be detached from the meshing relation with transmission gear at this time；Disk drove
Gear clockwise oscillation is crossed, when transition gear is engaged with transmission gear, transmission gear is moved output gear through transition gear band and revolved
Turn, output gear drives output shaft rotation.
Due to reciprocating motor high-frequency reciprocating rotary and stop certain time in engagement place so that driving gear can be with
The drive transmission gear of high frequency interval rotates, and then transmission gear can move output gear high frequency interval through transition gear band
Rotation, so output shaft nearly continuously rotates output under prolonged transmission.
When new energy vehicle needs to increase the output torque of speed changer during traveling, gear regulator adjustment connection
Plate moves up, and connecting plate is moved up through the dynamic second rotation ring set of the first annulus；The process that second rotation ring set moves up
In, the length of R will be progressively longer, and the rotary inertia of stored energy mechanism becomes larger, and the rotation speed of stored energy mechanism is also slower and slower
And the rotation speed of stored energy mechanism does not allow malleable.When connecting plate is moved to suitable position, stored energy mechanism energy under this state
More stable drives transmission gear rotation through propeller shaft sleeve；The transmission gear of rotation moves the rotation of output gear speed through transition gear band
Turn, output gear drives output shaft rotation, and the output torque of final output axis is matched with the traveling of new-energy automobile.Pass through shelves
Position adjuster adjusts the amount of moving up and down of connecting plate to adjust the torque of output shaft or output revolving speed：When adjustable plate moves up
When, the length of R, the rotation speed of stored energy mechanism reduces, and then the transmitting torque of transmission gear increases, output gear it is defeated
Torque also increases out；When adjustable plate moves down, the length of R shortens, and the rotation speed of stored energy mechanism becomes larger, and then transmits tooth
The rotation speed of wheel increases, and the output revolving speed of output gear also increases.
In speed changer in the present invention, realize that the gear of high strength drive only drives gear, transmission gear, transition tooth
Wheel and output gear, then namely only this four gears need high-intensitive and function admirable, so being compared to traditional electricity
The quantity of high-performance transmission gear in speed changer in electrical automobile will greatly reduce, and then save a large amount of cost；In addition
Smaller driving motor is mounted in speed changer of the invention, is still able to achieve by the adjusting of gear regulator big defeated
Torque and relatively quickly rotation output out, allow speed changer of the invention preferably to adapt to the electronic vapour under different road conditions
The traveling of vehicle.
Relative to traditional transmission technology, the present invention adjusts the amount of moving up and down of connecting plate by gear regulator to adjust
The torque or output revolving speed of whole output shaft, allow speed changer of the invention preferably to adapt to the electronic vapour under different road conditions
The traveling of vehicle；Only gear, transmission gear, transition gear and output gear is driven to need height additionally, due to speed changer of the invention
Intensity and function admirable, so the quantity of the high-performance transmission gear in the speed changer being compared in traditional electric car will be big
It is big to reduce, and then save a large amount of cost.The configuration of the present invention is simple has preferable using effect.
