• What is a transfer case?

Transfer case is an intermediate gearbox that transfers power from the transmission of a motor vehicle to the driven axles of four-wheel-drive, all-wheel-drive, and other multi-axled on- and off-road machines.  A part of the vehicle's drivetrain, it employs drive shafts to mechanically deliver motive power.  The transfer case also synchronizes the difference between the rotation of the front and rear wheels (only high-speed 4wd-Awd systems), and may contain one or more sets of low range gears for off-road use.

• What are the three types of transfer cases?

The transfer case differential is just like the differential in the axles.  It allows one output to spin at a different rate than the other to avoid driveline bind on hard surfaces.The three basic types of transfer cases are part-time 4WD, full-time 4WD, and active 4WD.

• What is the function of a transfer case ?

The transfer gearbox (a secondary transmission system) receives power from the transmission and sends it to both the front and rear axles, or just one (usually the rear.) This can be done with gears, hydraulics, or chain drive. On some vehicles, such as four-wheel-drive trucks or vehicles intended for off-road use, this feature is controlled by the driver. The driver can put the transfer case into either "two-wheel-drive" or "four-wheel-drive" mode. This was traditionally accomplished by means of a shifter, similar to that in a manual transmission. Increasingly it is electronically operated by a dashboard, center console, or shift lever switch.

A transfer case that allows alternating between 2-wheel drive and 4-wheel drive modes but lacks a center differential for coordinating axle speeds is known as "part-time". Some vehicles, such as all-wheel-drive (AWD) sports cars, have transfer cases that are not selectable, known as "full-time". Such a transfer case is permanently "locked" into AWD mode. In recent decades hybrids have been developed that share properties of each.
