Three-stage wet rear axle assembly

Abstract

A three-stage wet rear axle assembly comprises a rear axle housing (2), a rear axle shaft (7), a large bevel gear (8), -left and right clutches (4), left and right brakes (3); the rear axle housing (2) is fixed with left and right partition plates (10) which deives the inner cavity into a wet central area and left and right wet clutch brake area communiting with each other;A rear axle shaft (7) isprovided on the left and right partitions (10), A left and right clutch (4) and a left and right brake (3) are correspondingly installed in a left and right wet clutch brake area, The left and rightclutches (4) are connected to both ends of the rear axle shaft (7), the output end of the rear axle housing (2) is provided with a long inner and outer ring gear (21), the left and right brakes (3) are sleeved on the long inner and outer ring gear (21) and fixed with the rear axle housing (2), and the left and right brakes (3) are connected to the corresponding left and right clutches (4). The structure has the advantages of modular design, simple and reasonable structure, convenient disassembly and repair, labor-saving and labor-saving, good clutch and braking effect, small wear and tear, long service life and the like.

Description

Technical field [0001] The invention relates to the technical field of rear axles of agricultural and forestry machinery, in particular to a three-section wet rear axle assembly with convenient disassembly and repair and good heat dissipation effect. Background technique [0002] In the rear axle design of the existing agricultural and forestry machinery, the central transmission space in the middle section is a wet design, but the design of the two sides of the coupling and the design of the brake are both dry design, so that the friction plate of the clutch and the brake friction The disc is easy to wear, and the friction disc must be replaced after a period of time, otherwise it is easy to malfunction of the clutch and brake, which may cause accidents. Every time the friction lining of the clutch and brake is replaced, the whole machine must be opened. After a lot of time and energy disassembly process, the rear axle is hoisted down by a crane or crane to make the rear axle co...

AI Technical Summary

Problems solved by technology

Since the whole machine is in the hands of the user, and most of them cannot be done, the whole machine has to be shipped back to the company for update and replacement, and then the company sends the whole machine with replaced parts to the user. The whole process requires It consumes a lot of manpower, material resources and financial resources

[0004] At the same time, the original dry design of the rear axle will generate a very high temperature, and the rear axle that is too high will produce thick white smoke, which will shorten the service life of the vulnerable parts inside the rear axle

[0005] In response to the above problems, many manufacturers and people of insight have carried out research and development on the above problems, but so far no more reasonable products have come out
