if you know some geometry then it is very easy for you to start with understanding steering mechanism.here you can do it by only seeing how does it work and then closing your eyes for thinking about that for a while.and for the sight of view to confirm the best learning for you,i describe here the wheeled vehicle steering process here.though,there are even more steering phenomena left (e.g. war craft steering,hovercraft steering, thrust steering e.t.c).
look at the first 3-D figure,and be familiar with some components.
here,
1=steering wheel,
2=steering column,
3=rack and pinion,
4=tie rod,
5=kingpin.
we faced here some obvious terms those can be understood on due terminology.you could hear the name 'steering gear box' in past may be,then look at the point 3.here the gear goes for rotating the shaft connecting the two wheels.it's okay.but,think different,you might see that some trucks,lorries or buses and absolutely modern flexible cars have the steering wheel situated in the comfortable position to the driver.that connecting rod turns for different angles many times.something like a 'zigzag rod' i want to mean.you might also see the roller,huge carrier vehicles e.t.c. which have their driver space lots apart from the forward wheel and in height from driving surface.so,we frequently can't use a straight connecting rod there.we have to make it as like a shape as we want.and also we want to make the rod interact the axle rotating the wheel with a 90 degrees angle or sometimes with the shaft due to get the maximum power and torque.that's why we use a steering box here.and that looks like this picture below:
in the concerning figure positioned here,the first one shows the connection of 3 and 4 from the previous picture.just imagine what will happen if we turns the steering wheel clockwise?the steering column remains fixed in it's position and delivers power and torque to these the axle (not present in the first picture) make its displacements from right to left (or from the point of tire to the point where the tire is absent).and now our car make a 'right turn'. reverse tuning of steering wheel cause vice versa.if you want to know a more little about the steering box then analyze your concepts in the third figure by zooming it out.
here,
A=tie-rod ball joint
B=boot
C=steering column
D=steering joints
E=pinion shaft grommet
F=tie-rod locknut
G=ball joint boot
H=steering gearbox
this stuffs are for today.please warn me for my mistakes towards mhmmrm at gmail.com.
this page is under development,keep it on your right click daily.thanks.
