一、概述在拖拉机、联合收割机、建筑筑路机械,起重运输机械、工程机械等行走机械的转向系统中,广泛应用着摆线转阀式全液压转向器沟成的液压转向系统。这种转向系统结构紧凑,方向盘操纵力矩小,转向有力感,转向缸的移动距离和速度完全跟随方向盘的转角和转速。大型、重型行走机械的转向系统,国内外大致有下列几种方式: 1、助力式转向系统这种系统零部件多,结构不紧凑,布置困难,操纵力大,装拆维修困难,行走时容易出现蛇行现象。 I. Overview In the steering system of tractors, combine harvesters, construction road machinery, hoisting and transport machinery, construction machinery and other traveling machinery, the steering system of the cycloidal rotary valve type full hydraulic steering gear is widely used. This steering system has a compact structure, a small steering wheel steering torque, a strong steering feel, and a steering cylinder moving distance and speed that completely follows the steering wheel rotation angle and speed. Large, heavy-duty mobile steering system, at home and abroad generally have the following ways: 1, power steering system This system components and more, the structure is not compact, difficult to set up, the manipulation of large, difficult assembly and disassembly, easy walking Snake phenomenon appears.
