So This Is Christmas

Merry Christmas is such an infectious feeling I like to feel that way all year around.

So if you are visiting just before Christmas, just after Christmas or even here on Christmas day I am sure you will find something of interest for you and in the spirit of Christmas.

It may be said that Christmas is no longer a celebration but this must be spoken by people that have never had trouble closing their eyes on Christmas Eve in an expectation of what maybe left for them on the carpet under the tree.

I continue to look forward to the surprise on my Grandchild's faces to this day at Christmas events.

Merry Christmas - Merry Christmas - Merry Christmas

Function of a Transfer Case

By Fred Gagnon


Masses of vehicles are loaded with a four-wheel or all-wheel drive system. These drive systems utilize a number of mechanical components to help run correctly. One single part is the transfer case. A transfer case, often known as a transfer gearbox or transfer box, is a casing device that works together with the transmission in four-wheel drive and all-wheel drive autos.

The transfer case links to the transmission and front and rear car axles via drive shafts. Drive shafts are physical parts that permit rotation and deliver torque, or the force of momentum, to attached elements. The transfer case takes power out of the transmission and sends out that power to the front and rear axles using the shafts. It will help enable all 4 wheels to get torque concurrently.

A transfer case is typically gear driven or chain driven. Chain-driven transfer cases make use of a chain to safely move one axle, but can also move the 2 axles. Chain-driven transfer cases make use of specific roller chains, or chains built from pin links and chain links, to handle the front axle and the rear axle, hence permitting the case to move either both axles or one separately. Gear-driven transfer cases employ gear sets to transfer power to either the front drive shaft, or both front and rear drive shafts. Even so, newest transfer cases are chain driven.

Transfer cases frequently contain a minimum of one set of low-range gears. These gears are managed by a shifter or switch, and are intended to accelerate torque, or the force of motion, to the axles while retarding the automobile. Low-range gears are usually employed for such uses as load-pulling and rock crawling, or off-road running across coarse or higher terrain.

Motorists can handle the functionality of the transfer case by having a gear stick lever. This lever makes it possible for the driver to position the transfer case into two-wheel drive or four-wheel drive. Some other automobiles make use of an electronic switch instead of a shifter.
