AI Technical Summary

Technical Problem

Traditional agricultural tractor chassis have shortcomings in steering and shifting, resulting in large turning radii, cumbersome operation, and high labor intensity, making it difficult to meet the needs of flexible operation in narrow environments and complex terrains.

Method used

Employing a hydraulic wet clutch and hydraulic control system, it achieves power shifting and tank turn functions. The hydraulic control system controls the rotation of gears in the gearbox to achieve automatic gear switching and independent drive wheel power transmission, reducing the driver's workload and allowing the tractor to steer flexibly in narrow environments.

Benefits of technology

It enables tractors to maneuver flexibly in confined spaces, reduces the driver's workload, improves work efficiency and quality, and expands the scope of work scenarios.

Abstract

This utility model discloses a power-shift agricultural tractor chassis with tank-like turning function, including a front axle. A left front drive and a right front drive are respectively located on the left and right sides of the front axle. A gearbox is located behind the front axle. Space is provided between the gearbox and the front axle for installing an engine, allowing the engine to connect to the gearbox and the front axle for power transmission. Hydraulic wet clutches are located on both sides inside the gearbox. These hydraulic wet clutches, in conjunction with the tractor's hydraulic control system, can control the rotation of different gears, thereby achieving power shifting. A left rear drive and a right rear drive are respectively located on the left and right sides of the rear end of the gearbox. One hydraulic wet clutch is responsible for power transmission to the left rear drive, and the other hydraulic wet clutch controls power transmission to the right rear drive.
