Differential Case Product Overview
Differentials are fundamental to a car’s ability to turn.
In short, they transfer an engine’s torque to the wheels, splitting the power to enable them to spin at different speeds (rpm).
Without this arrangement, vehicles will be reliant on wheels locked to a single axle – limiting a driver’s ability to steer.
All of MAT Foundry Group’s transmission components, including differential cases, are specially cast and machined to meet the high-quality standards and tolerances that OEMs require.
How Do Differentials and Differential Cases Work?
There are various types of differential but the most common remains the Open Differential.
This setup sees two wheels mounted onto separate axles, supported by a single frame which allows them to revolve freely at different speeds.
Spokes are added to the inner end of both axles, allowing the wheels to spin separately when turned.
A crosspiece is introduced between the two which does allow for the pair to rotate straight and at the same speed where required.
A further support piece re-enforces this but prevents one tyre spinning faster than the other. It’s only when a pivot is introduced that this issue is resolved, and one wheel can be turned while the other is stopped.
How Do Differentials and Differential Cases Create Movement?
Another crossbar, and further spokes, are added to ensure it won’t turn too far. Extra spokes plug the gaps and allow for a smoother transition.
Over time gears were made thicker and stronger for automobiles. Their edges were cut in such a way as to fit together more easily and move silently.
A larger gear is also needed, one connected to a smaller gear which is itself attached to the power source – otherwise known as the drivetrain.
When turning inwards, we rely on inside wheels slowing and outside wheels speeding up. The differential system allows for this movement.
Differential Case Facts
The MAT Foundry Group produce approximately 6.3 million diff cases a year
The earliest automobiles were built minus differentials and powered one wheel on an independent axle
The open differential was the first of its kind
