ABSTRACT
In the process of travelling, steering is the most basic movement. We operate and control the automobile through the steering wheel, thus to achieve our intention of driving. On the modern automobile, the steering system is one of the most basic systems, it is also a essential unit which affect the automobile’s initiative secure. How to design the steering characteristic of automobile, enable the automobile to have good handling quality, which is always an important topic to various automobiles factory and the scientific research institution. Especially at the time ing to high speed, drivers ing personnel amateur, stream of vehicles crowded today, in view of the different crowd of driving, the design of automobile appears especially importantly.
This article mainly introduc automobile position and function system, and uses the correlate data to carry on the design which based on mechanical type rotation gear, carriy on the analysis to each kind of mechanical diverter advantages, designs the corresponding steering gear. Analysising the advantages and defect of different kind of streeing machinery,and carry on designing the whole and part on cad roof.
Key words:Drive; Steering System; Diverter; Design; Calculate
