Differentials الجهاز الفرقى

Differential Operation

If both drive shafts are travelling at the same speed the bevel pinions will not be turning on their axes. The bevel pinions will simply rotate with the bevel gears. This can be best explained by imagining the bevel gears an bevel pinons have been welded together
If one half shaft is stopped the bevel pinions will start turning on their axes and begin orbiting around the stationary bevel gear at the same time providing drive out through the other half shaft.
Although necessary for cornering differentials have a major drawback within agricultural applications in that should one wheel begin to spin freely then the remaining drive wheel will stop rotating (as shown above) and the vehicle becomes stationary.  For this reason it is necessary to have a differential that limits the amount of wheel slip. Such differentials are referred to as limited slip differentials.
 An alternative solution commonly found within agricultural machines is to introduce a locking mechanism that will lock the complete differential
