Description

Technical Field

[0001] This utility model relates to the field of steering device technology, specifically a steering device with a sliding collar structure. Background Technology

[0002] In reality, all vehicles need to turn. When agricultural machines and tractors are used on farmland, they need to control the direction of rotation. When turning on farmland, the traditional meshing steering method is used. When turning, the gears must be completely disengaged. After disengagement, the huge torque between the gear and the gear sleeve makes it difficult to disengage the gear, increasing the difficulty of operation for the operator and resulting in poor steering effect. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a steering device with a sliding collar structure, which solves the problem that traditional meshing steering methods are used when turning on farmland. During steering, the gears must be completely disengaged. After disengagement, the huge torque between the gear and the sleeve makes disengaging the gear difficult, increases the operator's difficulty, and results in poor steering performance.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a steering device with a sliding collar structure, including a housing, an operating mechanism is provided inside the housing, the operating mechanism extends to the outside of the housing, and half shafts are provided on both sides of the bottom end of the housing, and the half shafts are rotatably connected to the housing.

[0005] The operating mechanism includes a connecting rod. One end of the connecting rod has a vertical rod, and the top of the vertical rod has a steering rod. The other end of the connecting rod has a round rod, which is fixedly connected to the outer casing. The outer casing contains a gear, and two annular plates are fixedly mounted on both sides of the gear. Each annular plate has a groove on its surface, and there are two sets of grooves, with 2-20 grooves in each set. A collar is mounted on the outer side of the annular plate, and the collar contacts both the gear and the annular plate. One end of the half-shaft passes through the collar, and the surface of the half-shaft near the collar has a groove. A limiting medium is disposed inside the groove.

[0006] Preferably, a connecting spring is provided on the side of the collar away from the gear. The connecting spring is arranged around the outside of the half shaft. By placing the connecting spring on one side of the collar, the automatic separation of the collar from the gear can be reduced, and the automatic reset of the collar can be facilitated when the connecting spring is squeezed.

[0007] Preferably, the collar is slidably connected to the half-shaft, and an adjusting rod is provided at the bottom of the round rod.

[0008] Preferably, the outer circumferential surface of the collar is provided with a circular groove, and a fork is provided inside the circular groove. The fork is located in the circular groove on the surface of the collar, and the collar can be moved by the fork, allowing the collar to move along the half-axis.

[0009] Preferably, the limiting medium is either a ball or a roller, and the inside of the collar is configured with a large hole and a small hole.

[0010] Beneficial effects

[0011] This invention provides a steering device with a sliding collar structure. Compared with the prior art, it has the following advantages:

[0012] 1. This steering device with a sliding collar structure allows the adjusting rod to move and the shift fork to rotate via the movement of the connecting rod. At this time, the two ends of the shift fork are located in the circular grooves on the surface of the collar. The rotation of the shift fork allows the collar to move along the half-shaft. The collar is separated from the groove by the balls or rollers at the collar, so that the left half-shaft does not rotate, and only the right half-shaft can rotate. Conversely, the left half-shaft rotates, thereby cutting off the power transmission of one half-shaft to achieve tank-like steering with good steering effect.

[0013] 2. The steering device with a sliding collar structure has a connecting spring located on one side of the collar. The connecting spring can reduce the automatic separation of the collar from the gear, and facilitates the automatic reset of the collar when the connecting spring is squeezed.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 5. This utility model provides a technical solution: a steering device with a sliding collar structure, including a housing 1, an operating mechanism 2 is provided inside the housing 1, the operating mechanism 2 extends to the outside of the housing 1, and half shafts 3 are provided on both sides of the bottom end of the housing 1, and the half shafts 3 are rotatably connected to the housing 1.

[0022] The operating mechanism 2 includes a connecting rod 201. One end of the connecting rod 201 is provided with a vertical rod 202, and the top end of the vertical rod 202 is provided with a steering rod 203. The other end of the connecting rod 201 is provided with a round rod 204, which is fixedly connected to the outer casing 1. The outer casing 1 is provided with a gear 205. Both sides of the gear 205 are fixedly provided with annular plates 206. There are two annular plates 206. The surface of each annular plate 206 is provided with a hole groove 207. There are two sets of hole grooves 207, and each set has 2-20 hole grooves 207. A collar 208 is provided on the outer side of the annular plate 206. The collar 208 contacts the gear 205 and the annular plate 206 respectively. One end of the half shaft 3 passes through the collar 208, and the surface of the half shaft 3 near the collar 208 is provided with a groove 209. The groove 207 is provided with a limiting medium 215.

[0023] The collar 208 is slidably connected to the half shaft 3. An adjusting rod 211 is provided at the bottom of the round rod 204. A round groove 212 is provided on the outer circumference of the collar 208. A shift fork 213 is provided inside the round groove 212. The limiting medium 215 is either a ball or a roller. The inside of the collar 208 is provided with a large hole and a small hole.

[0024] Please see Figure 1-4 A connecting spring 210 is provided on the side of the collar 208 away from the gear 205. The connecting spring 210 is arranged around the outside of the half shaft 3. By placing the connecting spring 210 on one side of the collar 208, the automatic separation of the collar 208 from the gear 205 can be reduced, and the automatic reset of the collar 208 can be facilitated when the connecting spring 210 is squeezed.

[0025] During operation, the rotation of gear 205 causes the simultaneous rotation of the annular plates 206 on both sides and the simultaneous rotation of the half-shafts 3 on both sides. During steering, the left steering rod 203 rotates, causing the left vertical rod 202 to rotate simultaneously, improving work efficiency. When the vertical rod 202 rotates, since it is connected to the connecting rod 201, its rotation drives the rotation of the connecting rod 201, causing the connecting rod 201 to move along with the rotating rod. No manual operation is required. The end of the connecting rod 201 is connected to the adjusting rod 211, and its rotation causes the adjusting rod 211 to move. Because the top of the adjusting rod 211 is rotatably connected to the round rod 204, the rotation of the adjusting rod 211 is not affected. Furthermore, the rotation of the adjusting rod 211 causes the shift fork 213 to rotate, improving work efficiency. During the rotation of the shift fork 213... The end of the shift fork 213 is located in the circular groove 212 on the surface of the collar 208. The rotation of the shift fork 213 allows the collar 208 to move. Since the collar 208 is on the outside of the half-shaft 3, it can move along the half-shaft 3 and compress the connecting spring 210 at the collar 208, causing the connecting spring 210 to be in a deformed state. When the collar 208 does not move, the limiting medium 215 is located at the connection between the hole groove 207 and the groove 209. Between them, the movement of the collar 208 allows the limiting medium 215 to jump out. Since the limiting medium 215 is either a ball or a roller, it separates the ball or roller from the groove 207. After separation, the collar 208 will not rotate with the gear 205, so that the left half shaft 3 will not rotate, and only the right half shaft 3 will rotate, thereby cutting off the power transmission of one half shaft to achieve tank-like steering. Conversely, it will make the left half shaft 3 rotate, and the right half shaft 3 will be cut off from rotation.

[0026] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
