Four-wheel drive axle assembly for harvester

Abstract

The invention belongs to the technical field of a wheel type full-feeding combine harvester, and in particular relates to a four-wheel drive axle assembly for travelling of the wheel type full-feeding combine harvester. After a shifting slide gear positioned in the middle of a central transmission driving gear shaft of a speed changing box of a front axle is meshed with a two-stage straight toothed spur gear, a pair of spiral bevel gears with the transmission ratio of 1:1 are used for steering; an output shaft after steering is connected with one end of a universal transmission shaft; the other end of the universal transmission shaft is connected with an input end of a horizontal transmission shaft; an output end of the horizontal transmission shaft is connected with an input shaft of a transmission box; an input shaft of the transmission box is steered by a middle shaft and then drives an output shaft for raising a ground clearance to rotate; the output shaft is connected with a steering drive axle; and the front drive axle, the transmission box and the steering drive axle are connected with a stand of a vehicle. The invention has good trafficability and high reliability, and is suitable for various types of harvesters.

Description

Technical field: [0001] The invention belongs to the technical field of wheeled full-feed combine harvesters, in particular to a four-wheel drive axle assembly for walking of the wheel-type full-feed combine harvester. Background technique: [0002] The wheeled full-feed combine harvester is a harvesting machine for harvesting wheat, soybean, rice, corn and other crops, and is one of the important equipments of modern agriculture. With the advancement of science and technology, the technical level of the wheel-type full-feed combine harvester is also increasing, but the traditional wheel-type full-feed combine harvester has the following shortcomings: one is the traditional wheel-type full-feed combine The harvester is generally front-wheel drive, and the steering wheel is driven. When passing through a plot with poor adhesion in the field, the driving wheel will slip, the steering will not be flexible, and even the harvesting operation will not be completed. For example, t...

AI Technical Summary

Problems solved by technology

Due to the limitations of the original two-wheel drive axle structure and the steering drive axle, the angle between the universal joint transmission shaft and the input shaft of the steering drive axle is relatively large, the transmission shaft vibrates, the transmission efficiency is low, and the cross shaft of the universal joint transmission shaft is broken or broken. Needle roller bearing wear phenomenon; no protective cover is installed, weeds are often entangled on the drive shaft during harvesting operations, causing the harvester to stop working; in view of two-wheel drive, modified four-wheel drive, crawler-type full-feeding combined The shortcomings and defects of the harvester, the market needs to develop a four-wheel drive axle assembly for the full-feed combine harvester
