[0031] Referring to Figure 1 and Figure 4 , a steam locomotive transmission simulation device provided in an exemplary embodiment of the present disclosure includes:

[0032] A vehicle body 1, which has a driven wheel 11, a driving wheel 12, a driving component 13 for driving the driving wheel 12 to rotate, an upper simulation sliding rod 4 for simulating sliding, and a lower simulation sliding rod 41 for simulating sliding;

[0033] The unilateral synchronous connecting rod 2 is disposed on both sides of the vehicle body 1. The unilateral synchronous connecting rod 2 is eccentrically arranged with the driving wheel 12 and the driven wheel 11 at the same time. The unilateral synchronous connecting rod 2 is rotatably connected with the driving wheel 12 and the driven wheel 11 at the same time, and the unilateral synchronous connecting rod 2 always maintains a straight posture;

The lower sliding rod connecting rod 3 is rotatably connected with the unilateral synchronous connecting rod 2 coaxially, and the lower sliding rod connecting rod 3 is rotatably connected with the lower simulation sliding rod 41 coaxially;

[0035] The opposite-side transition connecting rod 5 is disposed on both sides of the vehicle body 1, and includes an upper sliding rod connecting rod 51 eccentrically arranged and rotatably connected with the unilateral synchronous connecting rod 2, a first transition connecting rod 52 rotatably connected with the upper sliding rod connecting rod 51 coaxially, and a second transition connecting rod 53 rotatably connected with the first transition connecting rod 52 coaxially. The second transition connecting rod 53 is rotatably connected with the upper simulation sliding rod 4 coaxially;

[0036] The opposite-side synchronous connecting rod 6 is arranged along the axis direction of the driving wheel 12. The opposite-side synchronous connecting rod 6 is fixedly connected with the first transition connecting rods 52 disposed on both sides of the vehicle body 1 at the same time, and the opposite-side synchronous connecting rod 6 only rotates about its own axis.

[0037] Exemplarily, referring to Figure 3 and Figure 4 , the driving wheel 12, the driven wheel 11, the upper simulation sliding rod 4 and the lower simulation sliding rod 41 are evenly disposed on both sides of the vehicle body 1.

The upper simulation sliding rod 4 and the lower simulation sliding rod 41 are both inserted into the vehicle body 1, and the vehicle body 1 provides a sliding path for the upper simulation sliding rod 4 and the lower simulation sliding rod 41 in the horizontal direction.

[0038] The driving wheel 12 includes a wheel body 122 and a wheel shaft 121. The outer peripheral wall of the wheel shaft 121 has protrusions inwardly and / or outwardly. A through hole adapted to the wheel shaft 121 is provided at the center of the wheel body 122. The wheel shaft 121 is inserted into and interference-fitted with the wheel body 122, so that the wheel body 122 can be detachably mounted on the wheel shaft 121 and is circumferentially clamped relative to the wheel shaft 121. Similarly, the driven wheel 11 also includes a wheel body 122 and a wheel shaft 121, and the wheel body 122 and the wheel shaft 121 of the driven wheel 11 have the same structure as the aforementioned driving wheel 12.

[0039] The single-sided synchronous link 2 is rotatably connected to the driving wheel 12 through a shaft body. Similarly, the single-sided synchronous link 2 is rotatably connected to the driven wheel 11 through a shaft body. When the driving wheel 12 rotates around its own central fixed axis under the action of the driving component 13 fixed inside the vehicle body 1, the single-sided synchronous link 2 hinged at an eccentric position on the driving wheel 12 through the shaft body rotates following it under the action of its own connecting shaft 75 body. At the same time, the single-sided synchronous link 2 will generate displacements in the vertical and horizontal directions, that is, it can be regarded as the single-sided synchronous link 2 rotating around its own shaft body while revolving around the rotating shaft of the driving wheel 12. Similarly, the single-sided synchronous link 2 also rotates around its own shaft body while revolving around the rotating shaft of the driven wheel 11.

[0040] One end of the lower slide bar link 3 is hinged to the single-sided synchronous link 2 through a shaft body, and the other end is hinged to the lower simulation slide bar 41 through a shaft body. The end of the lower slide bar link 3 is hinged to the hinged position of the single-sided synchronous link 2 and the driving wheel 12, and the lower slide bar link 3 and the single-sided synchronous link 2 share a shaft body. When the driving component 13 drives the driving wheel 12 to rotate, the lower slide bar link 3 is driven to rotate synchronously through the shaft body connected with the single-sided synchronous link 2, that is, it can be regarded as the lower slide bar link 3 rotating around its own axis while revolving around the rotating shaft of the driving wheel 12.

The aforementioned first distal end and second distal end are eccentrically arranged, and the included angle between the eccentric directions of the upper slide bar link 51 and the single-sided synchronous link 2 is set. The shaft body of the upper slide bar link 51 is circumferentially clamped with the shaft body of the single-sided synchronous link 2 on the driving wheel 12.

[0042] The outer wall of the opposite-side synchronous connecting rod 6 is in an uneven and non-smooth shape. For example, the end face of the opposite-side synchronous connecting rod 6 is in a cross shape. The two ends of the opposite-side synchronous connecting rod 6 respectively penetrate through two opposite side walls of the vehicle body 1 and then penetrate through the first transition connecting rods 52 on both sides of the vehicle body 1. Circular through holes with an inner diameter consistent with the outer diameter of the opposite-side synchronous connecting rod 6 are provided on the vehicle body 1. Through holes for accommodating the opposite-side synchronous connecting rod 6 are provided on the first transition connecting rods 52, and the first transition connecting rods 52 and the opposite-side synchronous connecting rod 6 are in interference fit. When the driving assembly 13 drives the driving wheel 12 to rotate, the rotation of the driving wheel 12 can drive the unilateral synchronous connecting rod 2 on the shaft body of the driving wheel 12, and then drive the upper sliding rod connecting rod 51 to rotate around its own shaft body and also revolve around the shaft body of the unilateral synchronous connecting rod 2. The first transition connecting rod 52 deflects under the action of the upper sliding rod connecting rod 51, and then drives the second transition connecting rod 53 to rotate, realizing the reciprocating linear motion of the upper simulated sliding rod 4; while the second transition connecting rod 53 rotates, the opposite-side synchronous connecting rod 6 rotates around its own axis, and then assists in driving the first transition connecting rods 52, the second transition connecting rods 53, the upper sliding rod connecting rods 51, the lower sliding rod connecting rods 3, and the unilateral synchronous connecting rods 2 on the other side of the vehicle body 1 to rotate, assisting the upper simulated sliding rod 4 and the lower simulated sliding rod 41 on the other side of the vehicle body 1 to perform reciprocating linear motion.

[0043] In this embodiment, the driving assembly 13 drives the driving wheel 12 to rotate. The driving wheel 12 drives the driven wheel 11 to rotate through the unilateral synchronous connecting rod 2. The lower sliding rod connecting rod 3 rotates synchronously with the unilateral synchronous connecting rod 2. The lower simulated sliding rod 41 realizes reciprocating linear motion under the rotation of the lower sliding rod connecting rod 3 and the limit of the vehicle body 1; the upper sliding rod connecting rod 51 rotates synchronously with the unilateral synchronous connecting rod 2, and then drives the first transition connecting rod 52 and the second transition connecting rod 53 to rotate synchronously. The upper simulated sliding rod 4 realizes reciprocating linear motion under the rotation of the second transition connecting rod 53 and the limit of the vehicle body 1; while the first transition connecting rod 52 rotates, the opposite-side synchronous connecting rod 6 rotates synchronously, and then realizes the reciprocating linear motion of the upper simulated sliding rod 4 and the lower simulated sliding rod 41 on the other side of the vehicle body 1.

[0044] In an exemplary embodiment of the present disclosure, referring to Figure 2 and Figure 3 , the wheel shaft 121 and the driving connector 7 are axially inserted. A driving connector 7 that rotates synchronously with the driving wheel 12 and extends towards the edge of the driving wheel 12 is fixed on the driving wheel 12. The unilateral synchronous connecting rod 2, the lower sliding rod connecting rod 3, and the upper sliding rod connecting rod 51 are all fixed on the driving connector 7.

[0045] Exemplarily, referring to Figure 2 and Figure 4The active connector 7 includes a wheel-side mounting block 71 for sleeved and circumferentially clamped with the wheel axle 121, a mounting rod 72 axially plugged and circumferentially clamped with the wheel-side mounting block 71, and a rod-side mounting block 73 fixed on the mounting rod 72 and synchronously rotated with the mounting rod 72, and the rod-side mounting block 73 is set at an angle with the wheel-side mounting block 71. The wheel-side mounting block 71 is integrally formed on the side of the driving wheel 12 away from the vehicle body 1, one end of the wheel-side mounting block 71 is located at the center of the driving wheel 12 and is provided with a through hole adapted to the shape of the wheel axle 121, and the other end extends to the edge of the driving wheel 12. The outer wall of the mounting rod 72 is in an undulating non-smooth shape, for example, the end face of the mounting rod 72 is in a cross shape, one end of the mounting rod 72 is plugged into the end of the wheel-side mounting rod 72 away from the center of the wheel body 122, and the other end of the mounting rod 72 extends in a direction away from the wheel body 122. One end of the rod side mounting block 73 is provided with a through hole adapted to the contour of the mounting rod 72 and is sleeved on the end of the mounting rod 72 away from the wheel body 122. The other end of the mounting rod 72 is provided with a through hole adapted to the shaft body of the upper slide rod connecting rod 51 and is hinged to the upper slide rod connecting rod 51 through the shaft body.

[0046] In this embodiment, refer to Figure 2 and Figure 4 The wheel body 122 of the driving wheel 12 is provided with a through hole extending along the direction of its own rotation axis and matching the profile of the mounting rod 72. The end of the mounting rod 72 facing the vehicle body 1 penetrates the wheel side mounting block 71 and the wheel body 122 of the driving wheel 12, so that the mounting rod 72 is plugged into the driving wheel 12. The mounting rod 72 bears the torsional pressure on the wheel axle 121 when the driving wheel 12 rotates, thereby extending the service life of the wheel axle 121 of the driving wheel 12. The mounting rod 72 is coaxially plugged with a bearing 74 for carrying the unilateral synchronous link 2 and the lower slide link 3. The bearings 74 have through holes matching the profile of the mounting rod 72. The bearings 74 are sleeved on the mounting rod 72 and are interference fit.
