[0002] Large mining trucks are core equipment in mine transportation, and their operational efficiency and safety directly affect mine production benefits. In recent years, unmanned mining truck technology has developed rapidly due to its core advantages of safety, efficiency, and low carbon emissions. However, the technology is not yet fully mature, and in some special situations, it is necessary to switch to manned driving mode to operate the vehicle.

Then, the bolt 43 passes through the groove and connects to the small groove 411 on the steering pump 41, so that the steering pump 41 and the connector 44 are installed together. The connecting plate 42 is installed on the base plate of the mining truck cab 10 through the bolt 43.

[0031] In this embodiment, as Figure 6-8As shown, the steering column 3 includes a housing 31, a mounting bracket 32, and a drive bracket 30.

The four fasteners 23 pass through the U-shaped groove 211 and the three screw holes 212 respectively, abutting against the bracket wall of the second drive bracket 34, thus fixing the ring 21 onto the second drive bracket 34. The fasteners 23 are determined by whether the U-shaped groove 211 is engaged with the second drive bracket. The limiting protrusion on the side wall of 34 is used to determine whether the ring 21 is installed in place and to adjust the axial height of the ring 21 installation; the support plate 22 includes a ring base plate 221, a bent plate 222 and a long plate 223. The bent plate 222 is "S" shaped. One end of the bent plate 222 is connected to the ring base plate 221 and the other end is connected to the long plate 223. The bottom of the ring base plate 221 is welded to the top of the ring 21 to form an integral shape. The long plate 223 has elongated holes 2231 on both sides. The stud 24 passes through the elongated holes 2231 and is connected to the steering wheel assembly 1 to fix the steering wheel assembly 1.

The first base 12 has a round hole 14 in the middle and several small holes 15 at its edge. The inner wall of the round hole 14 is threaded. One end of the rotor 13 is inserted into the round hole 14 and screwed into the thread, and the other end is inserted into the through hole 341 at the top of the second drive bracket 34. The stud 24 passes through the elongated hole 2231 and the small holes 15 to connect the first base 12 to the long plate, thereby fixing the first base 12 to the support plate 22 to fix the steering wheel assembly 1.

[0034] The working process of the unmanned steering wheel mechanism 100 in this embodiment is as follows: When the mining truck needs to be switched to unmanned driving, simply press the switch button on the dashboard, the motor starts to provide electric drive force for the steering wheel 11 to rotate, the steering wheel 11 rotates, the steering wheel 11 rotates and drives the rotor 13 to rotate, the rotor 13 drives the drive bracket in the steering column 3 to rotate, thereby starting the connected steering pump assembly 4, automatically steering, and realizing unmanned driving.

[0035] This embodiment provides an unmanned driving steering wheel mechanism 100. The unmanned driving steering wheel mechanism 100 connects the unmanned driving steering wheel assembly 1 to the drive bracket of the steering column 3 of a mining truck via an installation component 2, reducing modifications to the steering column 2. The installation component 2 has a simple, small, and low-cost structure. The installation accuracy of the ring 21 is determined by whether it engages with the limiting protrusion 342 on the second drive bracket 34. If not properly installed, the radial height can be adjusted via the U-shaped groove 211, adjusting according to assembly errors. Finally, the first base 12 of the steering wheel assembly 1 is fixed using fasteners 23 and studs 24, achieving multi-point fixing, simple and reliable installation, and precise installation of the unmanned driving steering wheel assembly 1.
