A kind of multi-shaft transmission and its automobile or aircraft

Abstract

The invention relates to a multi-shaft transmission which comprises an upper cover and a base, wherein a first gear shaft, a second gear shaft and a third gear shaft, which are distributed side by side, are mounted in a width W direction of the base; a sungear is arranged in the middle of the first gear shaft; the sun gear is in mesh connection to at least two planet gears; the left side of the sun gear is in coaxial sleeve connection to a planet gearconnecting base; the peripheral directions of the at least two planet gears are simultaneously meshed with a gear ring; the right side of the sun gear is in coaxial sleeve connection to a gear ring connecting frame; a first transmission gear and a second gear, which are convenient for mesh transmission of the planet gear connecting base and the second gear shaft, are arranged between the planet gearconnecting base and the second gear shaft; and a second transmission gear and a third gear, which are convenient for mesh transmission of the gear ring connecting frame and the third gear shaft, are arranged between the gear ring connecting frame and the third gear shaft. While the transmission is applied to a car or an aircraft, power input parts can be arranged at any positions ofthe left side and the right side of the first gear shaft, the second gear shaft and the third gear shaft, so that the power input parts are not required to be intensively arranged, and are changeable in arrangement.

Description

【Technical field】 [0001] The invention relates to transmission technology, in particular to a multi-shaft transmission and its automobile or aircraft. 【Background technique】 [0002] In the actual control process, different operating conditions often require that the driving force and operating speed can vary within a considerable range. In order to solve this problem, a transmission is set in the transmission system so that the power coupling can provide different operating speeds. . The main function of the transmission is to change the transmission ratio to meet different speed requirements. The power output by the engine is transferred to the main reducer through the transmission shaft after the torque and speed are changed by the transmission, and finally the power is transmitted to the drive shaft through the differential and the half shaft. [0003] However, most of the existing transmissions are single-power input, the structure is relatively complicated, the gear ...

AI Technical Summary

Problems solved by technology

[0003] However, most of the existing transmissions are single-power input, the structure is relatively complex, the gear ratio is relatively fixed and cannot be adjusted, and only one or several fixed gears can be used to change the speed, which cannot be adjusted flexibly; moreover, the existing transmissions are coaxially input through planetary gear components Output, high rigidity requirements on the shaft
