AI Technical Summary

Problems solved by technology

[0004] (1) The dual-motor system based on the planetary gear, the main rotation and the tilting motion are superimposed by the planetary gear, which has the characteristics of stable operation, uniform force on the slewing ring, and relatively high reliability; the mechanism is relatively complicated, and the planetary The gear bears a lot of force and wears seriously, so it is necessary to use dual motors for linkage. The driving power required for tilting is relatively large, and the energy consumption is relatively large.

[0005] (2) The differential-based dual-motor system uses dual motors to drive the main rotating slewing ring and the tilting slewing ring respectively, and the tilting is realized through the differential of the two slewing rings, which has high requirements for differential control and must be used Double motors are used for linkage, the driving power required for tilting is relatively large, and the energy consumption is relatively large

[0006] (3) For the lever-based slewing ring lifting system, the lifting movement of the tilting slewing ring can be driven by a motor or a hydraulic system, but a synchronization device or a control system is required to coordinate the lifting movement of the lowering slewing ring; Due to the limitation of vertical space, the stroke of the vertical movement of the lever is very limited, so the force on the lever is relatively large, the contact wear between the lever and the slewing ring is serious, and the operation is not stable; a dual power (dual motor) system is required for operation. The driving power is larger, and the energy consumption is larger

And the continuously variable transmission adopted relies on the metal belt friction between the fixed cone and the movable cone for transmission, which has low efficiency and the transmitted torque is limited. If the torque is too large, there is a possibility of slipping
