Description

Technical Field

[0001] The present invention relates to the technical field of control devices, and in particular to a power control device. Background Art

[0002] In mechanical transmission systems, power control devices are widely used. In the existing technologies, in most power control devices, the rotational power of the power input shaft is equal to the rotational power of the power output shaft. If the power of the power input shaft is large, the power of the power output shaft is also large. In this case, it is difficult to control the change of the power input shaft power by controlling the change of the power output shaft power. Summary of the invention

[0003] In view of the above-mentioned deficiencies of the prior art, the object of the present invention is to provide a power control device in which the rotational power of the power output shaft can be greatly reduced from the rotational power of the power input shaft. The power control device can control the change of the rotational power of the power input shaft with a large ratio by controlling the change of the rotational power of the power output shaft with a small ratio.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] A power control device comprises a set of planetary gear mechanisms, a power input shaft, a power output shaft, gear 1, gear 2, gear 3 and gear 4, wherein gear 1 and gear 2 are fixedly mounted on the power input shaft respectively, gear 3 is fixedly mounted on the planet carrier shaft in the planetary gear mechanism, gear 4 is fixedly mounted on the ring gear shaft in the planetary gear mechanism, the sun gear shaft and the power output shaft in the planetary gear mechanism are coaxial, gear 1 and gear 3 are meshed with each other, and gear 2 and gear 4 are meshed with each other.

[0006] A power control device comprises a set of planetary gear mechanisms, a power input shaft, a power output shaft, gear 1, gear 2, gear 3 and gear 4, wherein gear 1 and gear 2 are fixedly mounted on the power input shaft respectively, gear 3 is fixedly mounted on the ring gear shaft in the planetary gear mechanism, gear 4 is fixedly mounted on the planet carrier shaft in the planetary gear mechanism, the sun gear shaft and the power output shaft in the planetary gear mechanism are coaxial, gear 1 and gear 3 are meshed with each other, and gear 2 and gear 4 are meshed with each other.

[0007] Compared with the existing technology, the beneficial effect of the present invention is that the power output shaft rotational power of the power control device of this structure is smaller than the rotational power of the power input shaft, and the change of the large-proportion power input shaft rotational power can be controlled by controlling the change of the small-proportion power output shaft rotational power.

[0008] Since the planetary gear mechanism includes planetary gears and sun gears having the same function, the planetary gear mechanism described in the present invention includes a differential and various deformed planetary gear structures. BRIEF DESCRIPTION OF THE DRAWINGS
