The Transfer Case
If you have a vehicle with four or all-wheel drive, you have a transfer case. This device has been around since the early days of the automobile. Along the way, its appearance and development has changed dramatically. Yet, while its type and technology have advanced, its purpose has remained essentially the same.
What is a Transfer Case?
The term for transfer case may be transfer box, transfer gearbox, transfer gear case, jockey box or simply T-case. Whatever the name, this device is a system found in both all-wheel and four-wheel drive vehicles. It connects to the transmission as well as both front and rear axles through the use of drive shafts.
This device which splits the power between the front and rear axles, may contain gears or a chain-drive system. Overall the device has the ability to allow the driver to utilize a range of two-wheel and four-wheel capabilities – low range, high range and neutral.
Essential there are two types of transfer cases. These are
- Gear Driven – these use gear sets to drive the front shaft or to set into motion the front and rear shafts at the same time
- Chain Driven – this type uses a chain, separate roller chains or pin-link or chain-link chains to move a single axle or to move both front and rear axles simultaneously
Function of a Transfer Case
Basically, when you are trapped in mud, or up to your axles in muck, a transfer case allows you to get out of it. It forces both the rear and front axles to spin at equivalent speed. This gives the vehicle enough torque and traction to remove itself from its difficulty. It is also the transfer case that helps you have greater control when road conditions are adverse.
