When the all-terrain vehicle works, the power source connected with the input shaft 3 drives the input shaft 3 to rotate, and the input crank arm 18 and the epicyclic shaft 15 drive the epicyclic 14 to rotate around the input shaft 3; the sliding main shaft 13 and the sliding auxiliary shaft 16 perform two linear reciprocating motions of up and down, left and right in the cross-shaped slide 1701 along with the circumferential rotation of the epicyclic under the limiting action of the cross-shaped slide 1701, so that the epicyclic also performs the rotation while rotating around the circumference of the input shaft 3. When the epicyclic rotates for one circle around the input shaft 3, the epicyclic can rotate for two circles along the reverse direction; meanwhile, the sliding main shaft completes one up-and-down linear reciprocating motion in the cross-shaped slide way, and the sliding auxiliary shaft 16 completes one left-and-right linear reciprocating motion in the cross-shaped slide way.
As shown in fig. 3-6, under the action of the circumferential rotation of the epicyclic, one up-and-down linear reciprocating motion of the sliding main shaft in the cross slideway is divided into four actions of pulling down, pushing down, pulling up and pushing up. The method comprises the following specific steps:
1. and (3) pull-down action: the epicyclic wheel rotates along the anticlockwise direction under the drive of the circular motion of the epicyclic wheel shaft 15, and when the sliding main shaft moves to the top dead center of the cross-shaped slideway, the sliding auxiliary shaft 16 moves to the central point of the cross-shaped slideway; with the continuous rotation of the epicyclic wheel, the sliding main shaft is driven by the epicyclic wheel to move linearly downwards from the upper dead point of the cross slideway; meanwhile, the sliding auxiliary shaft 16 moves leftwards in a straight line from the central point of the cross-shaped slideway under the pushing of the epicyclic wheel.
2. Push-down action: when the sliding auxiliary shaft 16 runs to the left dead center of the cross-shaped slideway, the sliding main shaft runs to the central point of the cross-shaped slideway; along with the continuous rotation of the epicyclic wheel, the sliding auxiliary shaft 16 plays a fulcrum role at the left dead center of the cross-shaped slideway, so that the sliding main shaft is driven by the epicyclic wheel to continue to move linearly downwards through the central point of the cross-shaped slideway; meanwhile, the sliding auxiliary shaft 16 starts to move linearly to the right from the left dead point of the cross-shaped slideway under the pulling of the epicyclic wheel;
3. upward pulling: when the sliding main shaft moves to the bottom dead center of the cross-shaped slideway, the sliding auxiliary shaft 16 moves to the central point of the cross-shaped slideway again; along with the continuous rotation of the epicyclic wheel around the input shaft, the sliding main shaft is driven by the epicyclic wheel to move linearly upwards from the lower dead point of the cross slideway; meanwhile, the sliding auxiliary shaft 16 continues to move linearly rightwards from the central point of the cross slide under the pulling of the epicyclic wheel;
4. the upper pushing action is as follows: when the sliding auxiliary shaft 16 runs to the right dead point of the cross-shaped slideway, the sliding main shaft runs to the central point of the cross-shaped slideway again; along with the continuous rotation of the epicyclic wheel, the sliding auxiliary shaft 16 plays a fulcrum role at the right dead point of the cross-shaped slideway, so that the sliding main shaft is driven by the epicyclic wheel to move upwards continuously and linearly through the central point of the cross-shaped slideway; meanwhile, the sliding auxiliary shaft 16 starts to move leftwards in a straight line from the right dead center of the cross-shaped slideway under the pulling of the epicyclic wheel.
When the sliding main shaft runs to the top dead center of the cross-shaped slideway again, the sliding auxiliary shaft 16 returns to the center point of the cross-shaped slideway again. The epicycle wheel moves around the input shaft 3 in a circle, so that the sliding main shaft linearly reciprocates up and down in the cross-shaped slideway, the linear reciprocating acting force of the sliding main shaft is transmitted to the power output crankshaft through the connecting rod 12, and the output crank arm 11 drives the output shaft 10 to rotate to output torque.
Under the lever principle, the power input crankshaft is a labor-consuming lever as a whole. A power arm is arranged between the shaft wall of the power input crankshaft input shaft 3 and the shaft center of the power input crankshaft input shaft, the shaft center of the input shaft 3 is a fulcrum, and the shaft wall is a power point. The effective arm of force between the axis of the power input crankshaft input shaft 3 and the axis of the epicyclic shaft 15, i.e. the input crank arm 18, is the resistance arm, and the axis of the epicyclic shaft 15 is the resistance point.
The power output crankshaft is a labor-saving lever as a whole. The effective arm of force between the axle center of the power output crankshaft output shaft 10 and the axle center of the connecting rod shaft 9, namely the output crank arm 11 is a power arm, and the axle center of the connecting rod shaft 9 is a power point. A resistance arm is arranged between the axis of the output shaft 10 and the wall of the output shaft, the axis is a fulcrum, and the wall of the output shaft is a resistance point.
The resistance of the axis of the epicyclic shaft is the power of the axis of the connecting rod shaft 9. Because the effective arm length of the output crank arm 11 is twice as long as that of the input crank arm 18, the resistance of the power output crank shaft, namely the output torque force, is twice as much as the power of the power input crank shaft and is also twice as much as the input torque force under the lever balance formula. The power loss caused by friction is eliminated, and the output torque can also reach 1.5 to 2 times of the input torque.
As shown in fig. 7, in the operation of the power input crankshaft and epicyclic gear integrated mechanism, when the sliding main shaft receives a rotational movement force from the left side of the epicycle gear shaft at the top dead center, the sliding main shaft keeps the original tension force from the epicycle gear shaft unchanged under the limit of the cross slideway and slides downwards in the cross slideway; when the sliding main shaft slides to the connecting line A, B to form a ninety-degree included angle with the connecting line B, D, the sliding auxiliary shaft becomes a fulcrum sliding leftwards in the cross slideway. When the sliding auxiliary shaft becomes a fulcrum, the link action of the A, C connecting line also plays a role of leverage, the sliding main shaft can obtain a reaction force from the fulcrum of the sliding auxiliary shaft lever, and at this time, the sliding main shaft can be subjected to two acting forces: firstly, the tension of the revolving wheel shaft to the sliding main shaft; the second is the lever reaction force from the sliding attached shaft. When the angle formed by the A, B connecting line and the B, D connecting line is smaller than ninety degrees under the continuous rotation of the epicyclic shaft, the downward pulling force of the epicyclic shaft on the sliding main shaft is reduced, but under the reaction force of the lever fulcrum of the sliding auxiliary shaft and the pulling force of the epicyclic shaft, the pulling force of the sliding main shaft can still continuously maintain the original pulling force of the epicyclic shaft until the included angle between the A, B connecting line and the B, D connecting line reaches fifty degrees.
When the included angle between the A, B connecting line and the B, D connecting line is gradually reduced from fifty degrees, the pulling force of the sliding main shaft is gradually smaller than the original pulling force of the revolving wheel shaft under the condition that the reaction force from the sliding auxiliary shaft lever is kept; when the A, B connecting line and the B, D connecting line are overlapped on the left horizontal line, the pulling force of the revolving wheel shaft to the sliding main shaft is completely eliminated, the sliding main shaft only has the reaction force from the sliding auxiliary shaft lever, and under the labor-consuming lever principle of A, C connecting line, the stress of the sliding main shaft is only half of the downward pulling force of the revolving wheel shaft.
Under the action of the fulcrum of the sliding auxiliary shaft and the continuous downward rotation of the epicyclic shaft, the sliding main shaft can also move downward; when the angle formed by the A, B connecting line and the B, D connecting line is gradually increased, the thrust of the rotating wheel shaft borne by the sliding main shaft is also gradually increased; when the A, B connecting line is separated from the B, D connecting line by an angle of fifty degrees; the thrust borne by the sliding main shaft is consistent with the thrust of the epicyclic wheel shaft; until the sliding spindle reaches bottom dead center.
The pull-up action and the pull-down action have the same working principle, and the push-up action and the push-down action have the same working principle. The sliding main shaft can basically keep the original force from the epicycle shaft when the input crankshaft and the epicycle integral mechanism run continuously, which is the integral stress process of the epicycle shaft to the sliding main shaft.
When the power input crankshaft and the epicyclic wheel integral mechanism operate, the sliding main shaft can slide towards the axis of the input shaft when the sliding main shaft receives the rotating motion force from the epicycle wheel in the axial left direction at the top dead center; the AB connecting line and the BD connecting line take the revolving wheel shaft as an axis to realize the downward telescopic motion of the A, B connecting line and the B, D connecting line in a stackable way; when the sliding auxiliary shaft runs to the left dead center, the A, B connecting line is overlapped with the B, D connecting line on the horizontal line at the left, and the sliding main shaft is also overlapped with the shaft center D of the input shaft. When the sliding main shaft runs towards the bottom dead center on the axis of the input shaft, the AB connecting line and the BD connecting line stretch downwards; when the sliding main shaft runs to the bottom dead center, the A, B connecting line and the B, D connecting line are completely unfolded, and the A, B connecting line and the B, D connecting line are superposed on the vertical line below; meanwhile, the B, C connecting line and the B, D connecting line are overlapped on the vertical line below. When the sliding main shaft runs to the axis of the input shaft again at the bottom dead center, the A, B connecting line and the B, D connecting line run to the axis of the input shaft by upward contraction movement; when the sliding auxiliary shaft runs to the right dead center, the A, B connecting line and the B, D connecting line are overlapped on the right horizontal line again, and the sliding main shaft is overlapped with the revolving wheel shaft again. When the sliding main shaft moves far towards the top dead center on the axis of the input shaft, the A, B connecting line and the B, D connecting line move towards the top dead center in an upward unfolding motion; when the sliding main shaft runs to the upper stop point, the A, B connecting line is vertically arranged on the upper B, D connecting line and vertically arranged on the upper vertical line; at the same time, the B, C connection and B, D connection will again overlap in the upper vertical line. When the connecting line of A, B and B, D takes B as the axis D as the rotatable central fixed point, and the sliding main shaft makes a contraction movement from the top dead center to the axis of the input shaft, and the connecting line of A, B and B, D are overlapped on the horizontal line, the stroke distance from the sliding main shaft to the axis of the input shaft is twice as long as that of the BD connecting line, namely the effective arm of the input crank arm. When the sliding main shaft reaches the bottom dead center at the axis of the input shaft in the unfolding motion, twice the effective length of the B, D connecting line is obtained again. Namely, when the sliding main shaft and the axis of the input shaft respectively complete one motion in a contraction motion and an expansion motion, the effective length of the up-and-down reciprocating stroke distance of the sliding main shaft is four times of the effective length of the B, D connecting line and twice of the effective arm length of the output crank arm, so that the lever principle is utilized to achieve the purpose of boosting.
