文档介绍：摘要
本设计是一款轻型货车的转向器。通过有关资料对转向器的分类,结构性能,工作
原理,发展方向做一系列的调查了解,决定本设计的转向器,主要是根据汽车的类型、
前轴负荷、使用条件等来决定,并要考虑其效率特性、角传动比变化特性等对使用条
件的适应性以及转向器的其他性能、寿命、制造工艺等。
设计的主要内容包括总体设计方案的确定、主要性能参数的确定、齿轮齿条转向
器的尺寸计算和齿轮齿条的几何传动关系计算,对齿轮齿条进行了设计计算并进行了
校核,其中着重对主动小齿轮的齿根弯曲强度进行了校核。最后查阅有关资料对其进
行动力辅助液压装置的相关设计,主要对液压动力缸直径的计算,分配阀和反作用阀
有关参数的确定,油罐容积和油泵排量的设计等,根据计算利用 AutoCAD 画出装配图
和零件图。

Abstract
This design is a light wagon steering gear. Through the relevant material to the
classification of steering gear, structure performance, principle of work, doing a series of
development direction, decided to investigate the design of steering gear, mainly based on
the type, front axle load, use conditions to decide, and should consider its efficiency
characteristics, Angle changes to use characteristics of transmission ratio of the conditions
of the adaptability and other properties, life the products, manufacturing process, etc.
Design of the main content including overall design scheme, the main property
parameter determination of the determination of the size of the steering gear, gear rack
calculation and super-modulus gear geometry calculation of gear transmission relations, the
designing calculation rack and checks, which focuses on the initiative of the small gear
tooth root bending strength check. Finally consult relevant material to the auxiliary power of
hydraulic equipment related design, mainly to the hydraulic power cylinder the diameter of
the calculation, and adverse effect on distributing valve valve of parameters, volume and oil
pump oil tank displacement of design, according to the calculated using AutoCAD draw
assembly drawings and drawing.
Keywords: Vans, Redirector; Rack-and pinion; Steering system.
