Description

[0001] The present invention belongs to the technical field of reversing a forward-moving rotating disc, and more specifically, relates to a passive reversing device for a forward-moving rotating disc. Background Art

[0002] A passive reversing device with a forward rotating disc is a special type of steering system, typically used in heavy machinery or special-purpose vehicles, such as agricultural machinery, construction vehicles or certain types of military vehicles. The system is designed to improve the maneuverability and stability of the vehicle in complex or dynamic conditions, especially in applications that require operation in confined spaces or on uneven terrain.

[0003] However, common reversing devices still have the following disadvantages:

[0004] 1. If the passive reversing device only has a certain steering angle and cannot meet the needs of use, it may be difficult to adapt to changing terrain conditions, especially on uneven or irregular ground, thereby limiting the vehicle's operating range.

The limiting ring 33 moves together with the limiting ring 33, and the extension rod 30 is connected to the positioning ring 32 provided on the limiting ring 33 through the slider 31 fixed thereon. The overall smooth design of the slider 31 ensures the limitation without affecting the rotation of the limiting ring 33. The limiting ring 33 will be engaged with the connecting ring 19 during the upward movement, and at this time it will be disengaged from the engaging limit with the spur gear 15. The limiting rod 18 fixed on the output shaft of the starting motor 2 will drive the limiting ring 33 to rotate. The limiting ring 33 will drive the connecting ring 19 engaged with it to rotate during the rotation process.

The two bevel gears 24 above drive the two spur gears 25 to rotate together through the fixedly connected round rod 1 26 during the rotation. The two spur gears 25 will be respectively engaged with the two fixed bars 12 during the rotation. The two fixed bars 12 are movably engaged in the connecting seat 1. At this time, as the two spur gears 25 rotate, the driving device as a whole will be moved. In addition, by adjusting the position of the reversing device, it can help distribute the weight of the vehicle and improve the balance and stability of the vehicle.

[0030] Working principle:

[0031] The first step is that in the agricultural production process, the vehicle needs to flexibly adjust the direction according to the road conditions. First, the steering operation is performed through the steering wheel. The rotation of the steering wheel is transmitted to the steering gear 9 through the steering gear 9 input shaft. The mechanical components inside the steering gear 9 receive the rotational motion of the input shaft and convert it into linear motion. The linear motion generated by the steering gear 9 is transmitted through the tie rod 5. One end of the tie rod 5 is connected to the tie rod end 10. This component connects the tie rod 5 and the steering arm. The tie rod end 10 is connected to the steering arm. The steering arm is directly connected to the wheel. The movement of the steering arm causes the wheel to rotate, realizing the steering of the vehicle. The two pairs of dust covers 7 protect the steering system connection points, prevent dust and moisture from intruding, and extend the life of the components, while the two pairs of rubber fixing pads 6 provide flexible connections, reduce vibration and noise, and allow a certain degree of flexible movement to adapt to different road conditions, thereby ensuring better maneuverability and stability in complex terrain and different operating conditions.

[0032] In the second step, in actual applications, steering at a certain angle cannot meet the needs of use. Two fixing bars 12 are provided in the connecting seat 1. Two pairs of fixing plates 11 provided on the fixing bar 12 are connected and fixed to the agricultural machinery. By starting the motor 2, its output shaft will drive the limiting rod 18 fixed thereto to rotate together. During the rotation process, the limiting rod 18 will drive the limiting ring 33 engaged therewith to rotate together. During the rotation process, the limiting ring 33 will drive the spur gear 15 engaged therewith to rotate. The spur gear 15 is arranged as a whole in the protective shell 13 and the connecting seat 1, and is limited by the blocking ring 17 fixed under the connecting seat 1 to ensure stability during the rotation process. The spur gear 15 will drive the entire device to rotate together during the rotation process. The adjustment of the rotation angle can improve the flexibility of the overall steering. In agricultural or industrial applications, vehicles with flexible steering can complete turns and adjust directions faster, thereby improving work efficiency.

[0033] The third step is to start the electric push rod 3 and its output shaft will drive the extension rod 30 fixed thereto to move upward. The extension rod 30 will drive the limit ring 33 connected thereto to move together during the upward movement. The extension rod 30 is connected to the positioning ring 32 provided on the limit ring 33 through the slider 31 fixed thereon. The overall smooth design of the slider 31 ensures that the limit does not affect the rotation of the limit ring 33 while the limit ring 33 is engaged with the connecting ring 19 during the upward movement. At this time, it will be disengaged from the engagement limit with the spur gear 15. The starting motor 2 and the limit rod 18 fixed on its output shaft will drive the limit ring 33 to rotate. During the rotation, the limit ring 33 will drive the connecting ring 19 connected thereto to rotate together. The connecting ring 19 will drive the fixed ring 20 fixed thereto to rotate during the rotation. During the rotation, the set of tooth grooves 24 provided on the fixed ring 20 will drive the two connected spur gears 3 29 to rotate. The round rod 28 fixedly connected to the spur gear 3 29 is connected to the fixed ring 20. The connecting block 27 connected to it for rotation is set on the inner wall of the connecting seat 1. As the two round rods 28 rotate, the bevel gear 24 fixed thereon will be driven to rotate. The two bevel gears 24 will engage with the other two bevel gears 24 above during the rotation. The two bevel gears 24 above are oriented in the same direction to ensure the consistency of the direction of the subsequent drive fixed bar 12. The two bevel gears 24 above drive the two spur gears 25 to rotate together through the fixedly connected round rod 1 26 during the rotation. The two spur gears 25 will be respectively engaged with the two fixed bars 12 during the rotation. The two fixed bars 12 are movably engaged in the connecting seat 1. At this time, as the two spur gears 25 rotate, the driving device as a whole will be moved. When special operations are required or when working in a space-constrained environment, the movable reversing position can make it easier for the vehicle to be accurately positioned and operated. In addition, by adjusting the position of the reversing device, it can help distribute the weight of the vehicle and improve the balance and stability of the vehicle.

Many modifications and variations will be apparent to those skilled in the art.
