轻型货车转向系统设计
摘要
用来改变或保持汽车行驶和倒退方向的一系列装置被称为转向系统。汽车的转向系统是保证汽车够按照驾驶员的意愿在指定方向行驶的装置,因此它对于汽车的行驶安全性至关重要。
本设计是对一款轻型货车转向系统的设计。通过有关资料对转向器的分析,结构性能,工作原理,发展方向做了一系列的调查了解,最终根据汽车的类型,使用条件等方面选择了液压助力式的齿轮齿条转向系统。本次设计的主要内容包括转向系统的总体设计方案的确定、主要性能参数的确定以及齿轮齿条式转向器的尺寸计算和齿轮齿条的几何传动关系计算,并对齿轮齿条进行了校核。在这之后通过查阅相关资料进行了液压转向助力装置的相关设计,主要包括液压动力缸直径的计算,分配阀级反作用阀的相关参数确定等。除此之外对于转向操纵机构和转向传动机构(特别是转向梯形)的尺寸进行了设计。最后根据计算利用AutoCAD画出装配图和零件图。

Abstract
A series of devices, which are used to change or keep the direction of vehicle travel and backward, are called steering systems. Automobile steering system is a means to ensure that the car can be driven in the specified direction according to the wishes of driver, so it is very important for the safety of the vehicle.
This design is the design of a light truck steering system. through the analysis of the relevant information to the steering performance of structure, working principle, development direction did a series of investigation, finally according to the type of car, using conditions etc. Choose the hydraulic power steering gear and rack. This design mainly includes overall design scheme of steering system, the determination of main performance parameters and calculating the size of the gear rack type steering gear and gear rack and the geometric transmission relationship, and to check the gear and rack. After this through access to relevant data for the related design of the hydraulic steering device, mainly includes the calculation of hydraulic power cylinder diameter, grade distribution valve reaction valve related parameters. In addition to the steering mechanism and steering transmission mechanism (especially the steering trapezoid) the size of the design. According to the calculated using AutoCAD drawing assembly drawing and parts drawings.
