[0023] Example 1

[0024] AsFigure 1 and 2 As shown in the figure, the thrust bearing steering rotating assembly of the embodiment comprises a steering lever 1, a support frame 2, a rotating shaft 3, a locking structure 4 and two thrust bearings 5. The steering lever 1 is vertically arranged, and its lower end is connected with the upper end of the support frame 2. The rotating shaft 3 is horizontally arranged, and one end is fixedly connected with the support frame. The lower part of the support frame 2 is sleeved on the rotating shaft 3. The two thrust bearings 5 are respectively sleeved on the rotating shaft 3 and clamped on both sides of the lower end of the support frame 2. The locking structure 4 is arranged on the other end of the rotating shaft 3 and presses the thrust bearings 5, so that the thrust bearings 5 and the lower part of the support frame 2 are limited between the support frame and the locking structure 4.

[0025] In the thrust bearing steering rotating assembly of the embodiment, one thrust bearing 5 is clamped on each side of the lower part of the support frame 2. The stator part of the thrust bearing 5 is assembled on the rotating shaft 3, and the rotor part is tightly attached to both sides of the lower part of the support frame 2, and then locked by the locking structure 4. From the axial direction of the rotating shaft 3, the lower part of the support frame 2 is clamped and has good rotating performance. Therefore, during the forward and backward pushing and pulling operation of the steering lever 1, the rotor part of the thrust bearing 5 rotates with the lower part of the support frame 2 relative to the stator part (i.e. relative to the rotating shaft 3). Due to the rolling fit relationship between the rotor and the stator part of the thrust bearing 5, the friction is smaller compared with the traditional friction plate structure design. The overall structure design is simple and reasonable. The thrust bearing is self-sealed and can be maintained free of maintenance. The overall structure is simple and easy to assemble, which reduces the steering friction and makes the steering more labor-saving and convenient.

[0026] As a preferred embodiment, the support frame 2 is C-shaped in cross section, and an extension plate 21 is integrally arranged at the lower end of the support frame 2. The extension plate 21 is sleeved on the rotating shaft 3. The lower end of the steering lever 1 extends into the support frame 2 and is hingedly connected with the support frame 2.

[0027] In the above embodiment, the support frame 2 has a simple structure, and the extension plate 21, the rotating shaft 3 and the thrust bearing 5 are assembled well. At the same time, the C-shaped part of the support frame 2 can also be compactly assembled with the lower end of the steering lever 1.

[0028] As a preferred embodiment, the lower end of the steering lever 1 is vertically connected with a connecting rod 11. The two ends of the connecting rod 11 vertically penetrate through the two parallel plate surfaces of the support frame 2 and are rotatably connected with the support frame 2.

[0029] In the above embodiment, the lower end of the steering lever 1 is vertically connected with the connecting rod 11, which forms a vertical rotating assembly between the two parallel plate surfaces of the support frame 2. The structure design is compact, and the steering lever 1 can be rotated within a certain range relative to the support frame 2, which meets the gear conversion requirement of the steering lever 1.

[0030] In the embodiment, the two ends of the connecting rod 11 are respectively provided with a limiting member 12. The connecting rod 11 and the support frame 2 are assembled stably and are not easy to be separated by the limiting member 12.

[0031] In the embodiment, the two ends of the connecting rod 11 are respectively provided with a pin hole penetrating through the two ends along the radial direction, and the limiting member 12 is a pin penetrating through the pin hole. The assembly is convenient and simple.

[0032] As a preferred embodiment, the two parallel plate surfaces of the support frame 2 are provided with a limiting plate d, a torsion spring C is sleeved on the connecting rod 11, and the two feet of the torsion spring are respectively abutted against the support frame 2 and the limiting plate.

[0033] In the embodiment, the design of the torsion spring allows the operating lever 1 to rotate within a certain range relative to the support frame 2 during the gear engagement operation, and the operating lever 1 is reset by the torsion spring after the rotation occurs and the external force is removed.

[0034] In the embodiment, a soft shaft mounting hole is formed in the upper part of one plate surface of the support frame 2. The shaft head of the soft shaft B is inserted into the soft shaft mounting hole through a rod member, so that the shaft head of the soft shaft and the one plate surface of the support frame 2 are movably connected.

[0035] As a preferred embodiment, the locking structure 4 includes two locking nuts 41, and the other end of the rotating shaft 3 is provided with a thread, and the two locking nuts 41 are respectively screwed on the other end of the rotating shaft 3.

[0036] In the embodiment, the clamping cooperation of the thrust bearing 5 and the extension plate 21 can be achieved by screwing the two locking nuts 41.

[0037] In the embodiment, the locking structure 4 further includes a gasket 42, the gasket 42 is sleeved on the rotating shaft 3 and clamped between the locking nut 41 and the locking nut 41 close to it. The design of the gasket 42 makes the contact between the locking nut 41 and the thrust bearing 5 more closely, and the force transmission is more uniform and dispersed.
