We\u2019ve been taking you on a comprehensive journey through the commercial motor vehicle (CMV). With so much ground already covered, we are continuing on through some of the most vital components of a CMV.<\/p>\n

Large commercial trucks are technologically advanced vehicles<\/a>. But even as the digital age brings change to legacy components, it\u2019s still important to have a good working knowledge of the basics of how a CMV operates.<\/p>\n\n\n\n

In our last installment, we were taking a look at the electrical system. Today we will finish with the electrical system and start in on the real power behind a CMV: The drive train. So, let\u2019s dive right in!<\/p>\n

Electrical Circuits<\/strong><\/p>\n

Finishing out the electrical system includes covering the various circuits. First up is the cranking circuit. This is the circuit that moves electricity from the battery to a starter motor. You start the process by depressing a starter switch inside the vehicle.<\/p>\n

Next up is the ignition circuit. The ignition circuit provides the sparks for each cylinder. The spark ignites the fuel and air mixture within the engine itself. For diesel engines, an ignition circuit is not needed.<\/p>\n

Finally, you\u2019ll have to consider lighting and accessory circuits. These circuits provide electricity for the CMV\u2019s horn, lights, instruments, wipers and more.<\/p>\n

The Drive Train<\/strong><\/p>\n

Well, with the electrical system in our review mirror, it\u2019s time to move on to the drive train<\/a>. This is the part of the CMV that powers everything from the belly of the beast. The drive train is essentially a series of connected mechanical parts which convert power generated by the engine into torque and applies it to power the vehicle\u2019s wheels.<\/p>\n

There are several basic components of a typical drive train setup:<\/p>\n
