大马力拖拉机底盘控制液压系统介绍及优化设计

Introduction and Optimization Design of Hydraulic Systemfor Chassis Control of High horsepower Tractors

介绍了一例大马力拖拉机底盘控制系统,针对拖拉机在使用过程中出现的液压系统震动大、噪声大、管路压力损失大、管路布置复杂等问题,提出了一种底盘液压控制系统集成化设计的解决方案。该方案把分散的多种阀块集成化设计为一种阀组,优化了管路设计,通过装机后田间验证,解决了震动、噪声等问题,为拖拉机底盘液压系设计提供了一种可靠的思路及方法。

This article introduces the chassis control system of a high horsepower tractor and proposes a solution for the integrated design of the chassis hydraulic control system in response to the problems of high hydraulic system vibration,high noise,large pipeline pressure loss,and complex pipeline layout that occur during the use of the tractor.This scheme integrates multiple dispersed valve blocks into a valve group,optimizes pipeline design,and solves problems such as vibration and noise through field verification during installation.This provides a reliable approach and method for designing the hydraulic system of tractor chassis.
