the chain 20 is mounted on the first sprocket 5 and the second sprocket 6.
Further, the motor further comprises a first motor 24, wherein the first motor 24 is connected with one end of the double-sided rack 15, and the first motor 24 drives the double-sided rack 15 to reciprocate.
Further, the device also comprises a second engine 25, the second engine 25 is connected with the other end of the double-sided rack 15, and the first engine 24 and the second engine 25 jointly drive the double-sided rack 15 to reciprocate.
Further, the first engine 24 and the second engine 25 are four-stroke engines.
Further, the rack further comprises a first magnet 26 and a second magnet 27, wherein the first magnet 26 is fixed at one end of the double-sided rack 15, and the second magnet 27 is fixed on the rack 16 at the corresponding side of the first magnet 26.
Further, the rack further comprises a third magnet 28 and a fourth magnet 29, wherein the third magnet 28 is fixed to the other end of the double-sided rack 15, and the fourth magnet 29 is fixed to the rack 16 on the side corresponding to the third magnet 28.

Further, the first rotating shaft 9 or the second rotating shaft 10 is connected with the wheel.
Taking the perspective of fig. 1 and 2 as an example, assume that the locking direction of the first one-way bearing 11 is counterclockwise, the locking direction of the second one-way bearing 12 is counterclockwise, the locking direction of the third one-way bearing 13 is counterclockwise, and the locking direction of the fourth one-way bearing 14 is clockwise.
When the double-sided racks move rightwards in fig. 1, the third gear rotates anticlockwise, so that the outer ring and the inner ring of the first unidirectional bearing are locked, and the first rotating shaft is driven to rotate anticlockwise; at this time, the fourth gear rotates clockwise, the second one-way bearing is in a non-locking state, and the rotation of the outer ring of the second one-way bearing does not affect the inner ring, so that the second rotating shaft is not moved. The first rotating shaft drives the inner ring of the third one-way bearing to rotate anticlockwise while rotating anticlockwise, and the inner ring of the third one-way bearing does not drive the outer ring to rotate, so that the outer ring also does not drive the chain to rotate. The overall result is that the movement of the double sided rack to the right brings the first shaft to a counterclockwise movement.
When the double-sided rack moves leftwards in fig. 1, the third gear rotates clockwise, so that the outer ring of the first one-way bearing rotates clockwise and does not drive the inner ring of the first one-way bearing to rotate. At this time, the fourth gear rotates anticlockwise, the outer ring of the second unidirectional bearing drives the inner ring to rotate anticlockwise, and the inner ring drives the second rotating shaft to rotate anticlockwise. The second rotating shaft drives the inner ring of the fourth one-way bearing to rotate reversely and clockwise, so that the outer ring of the fourth one-way bearing is locked, the inner ring drives the outer ring to rotate anticlockwise, the outer ring drives the chain to rotate anticlockwise, the chain drives the outer ring of the third one-way bearing to rotate anticlockwise through the first sprocket, the inner ring of the third one-way bearing is locked, the inner ring of the third one-way bearing drives the first rotating shaft to rotate anticlockwise, the first rotating shaft drives the inner ring of the first one-way bearing to rotate anticlockwise, and acting force does not occur between the inner ring of the first one-way bearing and the outer ring. The overall result is that the double sided rack moves to the left to move the first shaft counterclockwise.
In summary, the left and right movement of the double-sided rack drives the first rotating shaft to move anticlockwise.
The first gear 1 and the second gear 2 are used as auxiliary, so that the double-sided rack motion is stable.
The locking direction of the first one-way bearing 11 being counterclockwise means that the outer race can only rotate clockwise while the inner race of the first one-way bearing is stationary, whereas the outer race cannot move counterclockwise.
The first magnet 26 is a permanent magnet, the second magnet 27 is an electromagnet, and the south and north poles of the electromagnet are periodically changed by computer control. And attractive force and repulsive force are periodically generated between the electromagnet and the permanent magnet, so that the double-side racks are pushed to reciprocate.
