The Role of a Transfer Case in a Car

Lots of automobiles come equipped with a four-wheel or all-wheel drive system. These drive systems employ a lot of mechanical components so they can operate proficiently. One particular part is the transfer case. A transfer case, identified as a transfer gearbox or transfer box, is a casing device that blends with the transmission in four-wheel drive and all-wheel drive automobiles.

The transfer case links to the transmission and front and rear car axles via drive shafts. Drive shafts are mechanical elements allowing rotation and transmit torque, or the force of momentum, to attached components. The transfer case is given power by the transmission and delivers that power to the front and rear axles through the shafts. It will help enable all 4 wheels to obtain torque concurrently.

A transfer case could be gear driven or chain driven. Chain-driven transfer cases employ a chain to safely move one axle, but can sometimes move the two axles. Chain-driven transfer cases work with separate roller chains, or chains made from pin links and chain links, to manage the front axle and the rear axle, therefore permitting the case to move the two axles or one on their own. Gear-driven transfer cases employ gear sets to transfer power to either the front drive shaft, or both front and rear drive shafts. Nevertheless, most up-to-date transfer cases actually are chain driven.

Transfer cases typically contain a minimum of one set of low-range gears. These gears are driven by a shifter or switch, and are meant to accelerate torque, or the force of motion, to the axles while decreasing the car. Low-range gears are often meant for such uses as load-pulling and rock crawling, or off-road driving on coarse or raised terrain.

Car owners can keep control of the operation of the transfer case by having a gear stick lever. This lever makes it possible for the driver to set the transfer case into 2-wheel drive or four-wheel drive. Some other automobiles make use of an electronic switch as opposed to a shifter.
