The working principle of the invention is realized by utilizing the rotational inertia, and the rotational inertia reflects the inertia of an object in a rotating state: the angular velocity of an object with a large moment of inertia is more difficult to change. Under the condition that the input torque and the mass are not changed, the moment of inertia of the rotating body is increased along with the increase of the radius of the rotating body, the rotating speed of the rotating body is smaller, and the angular speed of the rotating body is more difficult to change; under the condition that the input torque and the mass are not changed, the moment of inertia of the rotating body is reduced along with the reduction of the radius of the rotating body, the rotating speed of the rotating body is larger, and the angular speed of the rotating body is easy to change.
The driving shaft sleeve is fixed by the first L-shaped plate and can rotate around the axis of the driving shaft sleeve; the output shaft is fixed by the general fixing plate and can rotate around the axis of the output shaft; the transmission gear drives the first rotating ring sleeve to rotate through the driving shaft sleeve; the fixing ring is fixed by the first L-shaped plate, the disk is fixed by the fixing ring and the disk can rotate around the axis of the disk. The driving motor drives the driving gear to rotate through the second shaft; the reciprocating motor can drive the reciprocating gear to rotate in a reciprocating mode through the first shaft.
The reciprocating gear is meshed with the teeth on the disc, so that the reciprocating gear can drive the disc to rotate around the axis of the reciprocating gear in a reciprocating mode.
The axis of the output gear is collinear with the axis of the disc, and the design that the transition gear is meshed with the output gear is that the transition gear is fixed on the disc through a shaft and can swing back and forth around the axis of the disc in the process of the back and forth rotation of the disc; because the axis of the output gear is collinear with the axis of the disc, the transition gear can be always meshed with the output gear in the process of reciprocating swing along with the disc.
The transmission gear is respectively matched with the transition gear and the driving gear and has the following functions: in the process of reciprocating rotation of the disc, the disc drives the transition gear and the driving gear on the driving motor to swing in a reciprocating manner; when the disc rotates to the position that the driving gear is meshed with the transmission gear, the driving gear drives the transmission gear to rotate; when the disk rotates reversely to the state that the transition gear is meshed with the transmission gear, the transmission gear drives the transition gear to rotate, and then the transition gear drives the output gear to rotate.
The gear adjuster in the invention has the following functions: the connecting plate is adjusted to move up and down according to the running speed of the new energy vehicle, the connecting plate drives the second rotating ring sleeve to move up and down through the first ring to adjust the length of the R, and therefore the rotating speed of the transmission gear is changed, the output rotating speed of the output gear is changed, and the new energy vehicle is finally driven to run by matching with the driving motor.
When the distance between the first rotating ring sleeve and the second rotating ring sleeve is the farthest, the distance from the hinge point of the first connecting rod and the corresponding second connecting rod to the axis of the sliding rod is R, and the length of R is the shortest. The energy storage mechanism is formed by a first rotating ring sleeve, two first connecting rods, two second connecting rods and a second rotating ring sleeve.
When the transmission needs to work, the driving motor drives the driving gear to rotate at a high speed through the second shaft; when the reciprocating motor drives the reciprocating gear to rotate clockwise through the first shaft, the reciprocating gear drives the disc to rotate anticlockwise, and the disc drives the driving gear to swing anticlockwise; when the driving gear is meshed with the transmission gear, the driving gear drives the first rotating ring sleeve to rotate at a high speed through the transmission gear and the driving shaft sleeve; the first rotating ring sleeve drives the second rotating ring sleeve to rotate at a high speed through the first connecting rod and the second connecting rod.
When the reciprocating motor drives the reciprocating gear to rotate anticlockwise through the first shaft, the reciprocating gear drives the disc to rotate clockwise, the disc drives the driving gear to swing clockwise, and at the moment, the driving gear is disengaged from the meshing relation with the transmission gear; the disk drives the transition gear to swing clockwise, when the transition gear is meshed with the transmission gear, the transmission gear drives the output gear to rotate through the transition gear, and the output gear drives the output shaft to rotate.
Due to the fact that the reciprocating motor rotates in a reciprocating mode at high frequency and stays at the meshing position for a certain time, the driving gear can drive the transmission gear to rotate in a high-frequency clearance mode, the transmission gear can drive the output gear to rotate in a high-frequency clearance mode through the transition gear, and therefore the output shaft rotates approximately and continuously to output under long-time transmission.
When the output torque of the transmission needs to be increased in the running process of the new energy vehicle, the gear adjuster adjusts the connecting plate to move upwards, and the connecting plate drives the second rotating ring sleeve to move upwards through the first ring; in the process that the second rotating ring sleeve moves upwards, the length of R is gradually increased, the rotational inertia of the energy storage mechanism is gradually increased, the rotating speed of the energy storage mechanism is also gradually reduced, and the rotating speed of the energy storage mechanism is not easy to change. When the connecting plate moves to a proper position, the energy storage mechanism in the state can stably drive the transmission gear to rotate through the driving shaft sleeve; the rotating transmission gear drives the output gear to rotate at a high speed through the transition gear, the output gear drives the output shaft to rotate, and finally the output torque of the output shaft is matched with the running of the new energy automobile. The torque or the output rotating speed of the output shaft is adjusted by adjusting the up-and-down movement amount of the connecting plate through the gear adjuster: when the adjusting plate moves upwards, the length of R is lengthened, the rotating speed of the energy storage mechanism is reduced, the transmission torque of the transmission gear is increased, and the output torque of the output gear is also increased; when the adjustment plate moves downward, the length of R becomes shorter, the rotational speed of the energy storage mechanism becomes greater, and further, the rotational speed of the transmission gear increases, and the output rotational speed of the output gear also increases.
In the transmission, the gears for realizing high-strength transmission only comprise the driving gear, the transmission gear, the transition gear and the output gear, namely, only the four gears need high strength and have excellent performance, so that the number of high-performance speed change gears in the transmission is greatly reduced compared with that in the traditional electric automobile, and a large amount of cost is saved; in addition, a smaller driving motor is arranged in the transmission, and large output torque and faster rotation output can still be realized through the adjustment of the gear adjuster, so that the transmission can be better suitable for the driving of electric automobiles under different road conditions.
Compared with the traditional transmission technology, the transmission can adjust the torque or the output rotating speed of the output shaft by adjusting the up-and-down movement amount of the connecting plate through the gear adjuster, so that the transmission can be better suitable for the running of electric automobiles under different road conditions; in addition, because only the driving gear, the transmission gear, the transition gear and the output gear of the transmission are required to have high strength and excellent performance, compared with the high-performance speed change gear in the transmission of the traditional electric automobile, the number of the high-performance speed change gears is greatly reduced, and further, a great amount of cost is saved. The invention has simple structure and better use effect.

The axis of the output gear 16 is collinear with the axis of the disc 19, and the design that the transition gear 34 is meshed with the output gear 16 is that, as the transition gear 34 is fixed on the disc 19 through a shaft, the transition gear 34 can swing back and forth around the axis of the disc 19 during the back and forth rotation of the disc 19; since the axis of the output gear 16 is collinear with the axis of the disc 19, the transition gear 34 can always mesh with the output gear 16 during the reciprocating oscillation following the disc 19.
