Problems solved by technology

[0006] The existing gearbox cannot meet the requirements of 8 forward gears. For special machinery such as motor graders, 8 forward gears are required to meet the needs of different working conditions
In addition, in the existing gearboxes, the adjustment range of the gear speed ratio can only be realized in the range of 0.6 to 6.

Abstract

The invention relates to a modular design gearbox and a gear realization method. The gearbox includes a box body and a drive shaft arranged in the box body, 7 intermediate shafts and an output shaft, and fixed gears are arranged on the drive shaft and the output shaft , each intermediate shaft is provided with a fixed gear and a floating gear is installed through a clutch. The gearbox can achieve the highest forward 8-speed and reverse 4-speed mode, which meets the needs of special machinery for 8 forward gears. At the same time, it can control the combination of different clutches and can be adjusted to forward 7 speeds, reverse 3 speeds, forward 6 speeds and backward 3 speeds, etc. Different engine requirements; in addition, without changing the transmission route, the speed ratio of each gear of the gearbox can be flexibly adjusted; secondly, the gearbox can realize different speed ratios by changing or deleting some parts without changing the box body and gear requirements; keep the gearbox box unchanged, realize the modular design of the gearbox, increase the universalization rate of gearbox parts, and reduce the production cost of the gearbox.

Description

technical field [0001] The invention relates to the technical field of gearboxes, in particular to a modular design gearbox and a gear realization method. Background technique [0002] At present, construction machinery gearboxes can be divided into two types: coaxial type and balance shaft type according to the arrangement of transmission shafts. The coaxial gearbox is mainly the coaxial input shaft and output shaft of the gearbox, which is mainly used in engineering vehicles where the axis of the engine output end and the axis of the input end of the drive axle are in the same plane; There is a height difference between them, and it is mainly used in engineering vehicles with a certain axle drop between the engine output shaft and the drive axle input axis. [0003] The coaxial gearbox mostly adopts a planetary gear structure for power transmission and gear switching. The gearbox with this structure has a compact structure and requires less space, but the structure is mor...
