AI Technical Summary

Technical Problem

In the context of large feeding volume, high-power and high-end development, the existing harvester gearbox has insufficient transmission power and gear shifting comfort, poor power, poor operating performance, poor durability, and complex driving brake and parking brake systems. It takes up a large space, has high manufacturing cost, and has limited adaptability to the differential lock function, resulting in insufficient ability to escape.

Method used

Using electro-hydraulic control wet multi-plate clutch, differential lock and brake, it realizes no-power interruption shifting and non-stop differential locking, simplifies the operation of getting stuck in the car, improves ground adaptability and passing performance, reduces brake space volume, and improves structure Compactness and integration.

Benefits of technology

It realizes shifting without power interruption during operation, improves adaptability and operating performance, improves braking comfort and service life, is suitable for long-distance driving and heavy-duty work, has high adaptability to road conditions, and strong handling and durability.

Abstract

A power shift gearbox of a harvester comprises a box body, an input shaft arranged in the box body, an intermediate shaft parallel to the input shaft, a differential mechanism connected with the intermediate shaft, and a half shaft connected with a half shaft gear spline of the differential mechanism and parallel to the intermediate shaft, a second-gear clutch and a third-gear clutch are arranged on the input shaft, and a first-gear clutch is arranged on the intermediate shaft. The transmission is characterized in that the two half shafts are respectively provided with a brake which is fixedly connected with the box body, one half shaft is provided with a differential lock which is fixedly connected with the differential mechanism, the second-gear clutch, the third-gear clutch and the first-gear clutch are both wet-type multi-disc clutches which are controlled in an electro-hydraulic mode, and the second-gear clutch, the third-gear clutch and the first-gear clutch are arranged on the box body. The brake is a wet-type multi-disc brake which is electrically and hydraulically controlled and adopts a running and parking integrated mode, and the differential lock is a wet-type multi-disc differential lock which is electrically and hydraulically controlled. The invention is suitable for long-distance driving and heavy-load work, and has the advantages of strong durability and high adaptability to road conditions.
