Problems solved by technology

[0004] For some main engines such as loaders, they only perform the shoveling operation cycle of forward 2 gears, forward 1 gears and reverse 2 gears in a small area. Too many gears will lead to cumbersome operations and lower efficiency. There is a demand for fewer gears for the gearbox. If the multi-gear gearbox suppresses the combination of some clutches to achieve fewer gears, the actual number of parts will not be reduced, which will cause unnecessary waste.
Redesigning and developing a new structure of less-gear gearbox will not only increase the design cost, but also it is difficult to ensure the commonality with the original multi-gear gearbox components, resulting in increased production costs
[0005] On the other hand, gearboxes in the field of construction machinery are divided into two types: planetary gearboxes and fixed-shaft gearboxes according to the form of gear trains. The former planetary gearbox has a compact structure and requires less space, but has a complex structure and higher precision requirements. The fixed-shaft gearbox has a simple structure design and is easy to realize variable gear numbers and gear ratios. It has strong adaptability, is convenient to manufacture and maintain, and can meet The requirements for flexibility and modularization of construction machinery gearboxes are the development trend of the high-end market for construction machinery in the future

Abstract

The invention relates to a modular design gearbox and a gear realization method. The gearbox includes a box body, a drive shaft, four intermediate shafts and an output shaft. The gearbox has a layout of six shafts, wherein the drive shaft S1, the intermediate shaft S4, 2 clutch bags are installed on the intermediate shaft S5, and 1 clutch bag is installed on the intermediate shaft S2, such a structure has a short transmission path and better stability. The gearbox uses 6 shafts and 7 clutches to achieve a maximum forward speed of 8 speeds and a reverse speed of 4 speeds. The speed ratio range is wide and can be adjusted flexibly. By reducing some parts, it can realize a mode with fewer gears, realize modularization, and improve Versatility, reducing the production cost and use cost of the gearbox. At the same time, the forward gear is realized by the combination of two clutches and four gear meshes, and the reverse gear is realized by the combination of two clutches and three gear meshes. The transmission path is short and reliable. high.

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] There are many types of main engine products of construction machinery and the demand for a single type is relatively small. It is not realistic to design and develop gearboxes for various main engines. This requires that the gearboxes applied to construction machinery can cover a variety of products with similar power ranges. The working conditions of main engine products are complex, and the number of gears and transmission ratio requirements are also different, which puts forward higher requirements on the number of gears and the flexibility of gear ratios and the versatility of parts of construction machinery gearboxes. [0003] For the main engine with multi-gear requirements, customers have higher and higher requirements for product smoothness, which requires the gearbox to have more gea...
