[0022] Reference Figure 2The reversing mechanism 9 includes a connecting rod 91, a motor 92 is connected to the top of the connecting rod 91, a chassis 93 is connected to the top of the motor 92, an output end of the motor 92 passes through the connecting rod 91 and is rotatably connected to the outer side of the rotating base 10, and the connecting rod 92 is driven by the motor 92 to tilt the inclined end cover 8 to a certain angle.
[0023] Reference Figure 2 The rotating base 10 is provided with a connecting oil circuit corresponding to the oil pipe 1 11 and the oil pipe 2 12, and the oil distribution plate 17 is provided with non-connecting oil circuits corresponding to the oil pipe 1 14 and the oil pipe 2 15, so as to change the rotation direction of the output shaft 195 through different oil inlet and outlet directions.
[0024] Reference Figure 1 The rotating mechanism 19 includes a rotating cylinder body 191, a cavity is opened inside the rotating cylinder body 191, a plunger rod 192 is slidably connected in the cavity, one end of the plunger rod 192 is movably connected to a movable connecting rod 193, one end of the rotating cylinder body 191 is provided with an output shaft 194, one end of the output shaft 194 extends through and extends to the outside of the sealed cabin 16 and is provided with a bevel gear plate 195. The rotating cylinder body 191 is used to convert hydraulic energy into rotational mechanical energy through the cooperation of the plunger rod 192 and the inclined plate 18.
[0025] Reference Figure 1 One end of the movable connecting rod 193 is slidably connected to the swash plate 18, so that the rotating cylinder body 191 moves along the swash plate 18.
[0026] Reference Figure 3 The tilting end cover 8 is provided with a movable hole, and one end of the connecting shaft 4 passes through the movable hole and is connected to the rotating block 5 to prevent the tilting end cover 8 from hindering the movement of the connecting shaft 4 during the tilting process.
[0027] The implementation principle of the optimization control device of the loader transmission mechanism of the embodiment of the present application is as follows: during operation, the transmission shaft 1 increases the power of the connecting shaft 4 through the transmission gear 2 and the driven gear 3 to rotate the rotating block 5. During the rotation of the rotating block 5, the movable connecting rod 7 connected to one end of the piston block 6 is driven to slide along the inclined end cover 8. The starting motor 92 drives the connecting rod 91 to tilt the inclined end cover 8 at a certain angle. Under the restriction of the movable connecting rod 7 and the rotation of the rotating block 5, the piston block 6 performs a linear reciprocating motion in the cavity of the rotating block 5. Due to the inclination of the inclined end cover 8, the strokes of the piston blocks 6 on both sides of the rotating block 5 are different, which leads to different compression degrees of the hydraulic oil, so that the oil circuits in the rotating base 10 have different pressure differences. The movement of the piston block 6 on the side where the inclined end cover 8 is tilted The stroke is short, and the pressure of the hydraulic oil is high when it passes through this place, so the hydraulic oil is output to the outside. At this time, the hydraulic oil is output through the oil pipe 11 and input into the oil distribution plate 17 through the oil pipe 14, and cooperates with the inclined plate 18 and the rotating mechanism 19 to convert the hydraulic energy into rotational mechanical energy. From this principle, it can be seen that when the inclined end cover 8 tilts to the other side, the hydraulic oil enters through the oil pipe 11, and the oil pipe 2 12 is output through the oil pipe 2 15 to enter the oil distribution plate 17, thereby changing the rotation direction of the mechanical energy. When the inclined end cover 8 is no longer tilted, since the pressure on both sides of the rotating block 5 is equal, the hydraulic oil circulates between the oil pipe 11, the oil pipe 2 12 and the three-phase four-way solenoid valve 13, and the rotating mechanism 19 is no longer subjected to force and stops rotating. The bevel gear plate 195 is fixed by the ear plate 20 to better output power to the outside.
