Cars can be moody animals. They go through periods of being perfectly at ease with you, and then there are other times when they become whiny and resistant. There's something called a drivetrain that this is true of, and before you look for drivetrain repair in Sandy Springs, here's an explanation of what the drivetrain is, what it isn't, and phrases that it can be easily confused with. What is a Drivetrain? A drivetrain is a combination of parts that work together to power the vehicle's wheels forward. It's composed of a driveshaft, CV joints, the differential, the axle shafts, and the U-joints. A U-joint is another way of saying "universal joint." It is a flexible pivot point for the driveshaft to deliver power at varying angles. CV joints are, in full, called constant-velocity joints, and are joints in the driveshaft that turn the drive wheels at a constant velocity while being able to bend in any direction. The differential is where the power stops just before it starts spinning the wheel axles on the vehicle, and the axle shaft is a single shaft that rotates on either side of the differential to deliver that spinning power to the drive wheels. What It's Not The term driveshaft gets confused with drivetrain, but the driveshaft is actually just a component included in a drivetrain. The driveline refers to the chain that travels from the engine to the drive wheels, up to but not including the transmission. A drivetrain excludes the engine, but if it is included, then that system of parts is referred to instead as a powertrain. What's with the Transmission? It's common for people to get confused about this fact, so listen closely and you'll be a sudden vehicle expert: The drivetrain and the transmission are actually two separate concepts. The transmission is what keeps the engine churning in synch with the wheels, but essentially the drivetrain is what communicates the power from that transmission turning directly to the wheels. Technically speaking, the transmission is its own system apart from the drivetrain that just happens to sync up with it as it moves your vehicle. Now you know what a drivetrain is and isn't, and have a better idea of the parts that are involved in repairs and maintenance specific to the drivetrain as you continue your search for drivetrain repair in Sandy Springs, GA.
