No need to read through manuals as thick as a brick to understand the components that make up your car. From 1930s black-and-white clips outlining the basics of your intermission to modern graphics explaining complicated transmissions, these videos will teach you more than you ever knew virtually how cars are made.

The leaf leap is the oldest and simplest suspension. Several long, thin steel leaves are bound together in a pack by clamps. One finish of the pack is connected to the vehicle's frame vis a bushing. The other terminate uses a shackle that tin can move for and aft. Combined with the flexing of the leaf pack itself, that provides the suspension motion and cushions the ride.

Most modernistic pickup trucks still use this setup for their rear suspension because of its simplicity and durability. The Chevrolet video from the 1930s shows how the intermission works and outlines its drawbacks for passenger auto use.

2 The manual transmission

The old-school manual might be an endangered species, but y'all should learn to drive you—and learn how it works. Manual transmissions provide a straight connection to the machine—one that makes the whole experience of driving a more rewarding activity.

The job of the manual transmission is to transmit the engine's torque from the input shaft, through various gearsets to the output and on to the axle and driven wheels. Those gearsets in the transmission combine with the gears in the axle to multiply the torque of the engine and get the car moving. This basic animation shows how the gears are selected, and what these gears actually practise when you move the shifter.

Back in the 1930s, a vacuum sleeping room added a new level of ease for shifting when the manual gearshift lever was moved to the column to free up floor space. Make sure to watch until the very end, when, only as the announcer proclaims "greater safety for all!" we see a mom place her child right on the front demote seat side by side to her with no visible seatbelt. Yikes.

This incredible animation by Toyota outlines the process by which an engine produces power. It covers the typical cylinder configurations also equally basic terms like compression ratio, displacement, and the differences between single and double overhead cam engines. The video as well explains some of today'south newer engine technologies, like variable valve timing. It's worth watching more than once.

A clutch let the driver smoothly couple and de-couple the engine from gearbox so that power can menstruation from one to the other without stalling the engine or damaging to other components. Every fourth dimension you push the clutch pedal, the pressure plate releases pressure level from the clutch disc, separating it from the engine'south flywheel. Releasing the clutch pedal (after a new gear is selected, for example) creates friction between the disc and flywheel, which connects the transmission to the engine once more, sending ability to the wheels.

Dorsum in the mid-1930s, Chevrolet developed what must have been some expensive and time-consuming films to explain in detail how automotive systems worked. The narrative in this one likens the squeaks and rattles in an outdated car frame to those in old houses. Cars at this time used torso-on-frame construction like pickups still do today, though many of our modernistic trucks skip the engineering fixes outlined here because they use ultra-loftier-force steel alloys that make them far more than robust and much lighter than these earlier designs.

Can you lot imagine having to creepo-outset the car every time yous need to run an errand? In the early days of driving, people would have to start vehicles with a hand crank, an unpredictable science that sometimes resulted in a cleaved arm if the crank kicked dorsum. Not fun. Although electric starters began to appear on cars in the 1910s, cars like the VW Beetle even so included a crank upwards until the 1950s. This 1957 US Army film explains the wonder of electrical starter motors. Interestingly, these old military trucks withal used a starter switch. Modern cars and trucks accept them integrated with the ignition.

Perchance more than any other automotive component, the automated transmission became so ubiquitous then apace that most people don't even detect it's in that location. Really, that'southward the automatic'south job: to shift gears without drawing attention to itself. But there's plenty going on behind the scenes, and this video demonstrates.

The automatic was invented dorsum in 1921; today's most advanced version have up to 9 speeds and manual shift control.

Continuously Variable Transmissions (CVT) have gained popularity as carmakers hunt for fuel economy gains anywhere they tin find them. Dissimilar a conventional manual or automatic transmission, a CVT has no fixed gears within the manual instance. Instead, CVTs use 2 adjustable pulleys with a chain in between to modify ratios.

Picture a bicycle chain moving upward and down the sprocket gears in the back and from one of the large chain rings to a smaller one up front. As the diameter of these discs change, then does the ratio. That'south the principle behind the CVT. This curt blitheness is Subaru-specific but does a great job explaining the tech in simple terms.

After nigh two minutes of showing us skiers and ice skaters, the journalist finally gets effectually to explaining that skates and skis glide upon a thin layer of water on superlative of the ice. Information technology's a lubricant, and the video goes on to explain how lubricants piece of work in our everyday life. The well-nigh interesting part come halfway through, when they begin to explain why oil is needed as a lubricant between metal parts. A cut-away of an engine shows exactly how the oil is routed from the oil pump in the pan up through the diverse bearings, valves, rods, and pistons.

Like the clutch, the torque converter acts as a polish connection between a transmission manual and the engine. The torque convertor is a fluid coupling that's far more complex than the clutch but tin can be perfectly tailored to conform the ability and torque characteristics of a particular powertrain. The converter tin can multiply torque, acting as an extra gearbox of sorts for a brusque time equally a car leaves the line. Here'southward how this slick coupling works in concert with an automatic manual.

The turbo is back. What seemed like futuristic performance tech dorsum in the 1980s is now completely mainstream, cheers to automakers chasing better mpg. The industry has at present turbocharged the engines in practically every segment, from economy cars to full-size pickup trucks.

Why? Because turbos allow small engines to deed like larger ones when needed. Turbos take normally wasted frazzle gases and uses them to run a compressor, which pressurizes and feeds more than air to the engine. Let's let this video explain.

Car designers were experimenting with aerodynamics a century ago. At that fourth dimension information technology was called "streamlining," and by the 1930s American cars were beginning to look Fine art Deco and perform much improve equally they cut through the wind. Sadly, though the most advanced automobile of that time, the Chrysler Airflow, was largely a flop.

What this film shows more anything is how far nosotros've come. No, the globe of tomorrow didn't actually evangelize elevated highways that tin can back up 120 mph travel. But nosotros do accept big, roomy vehicles that cut through the air meliorate than the slipperiest sports cars did non that long agone.

Similar a turbo, the supercharger forces more air into the engine to boost horsepower. But it does so in a totally different fashion. Where turbochargers use frazzle gas to turn the compressor and pressurize air, superchargers are driven off the engine'due south crankshaft past a chugalug. In the old days, turbo engines suffered from lag—it took some fourth dimension for the exhaust gas to create boost. Superchargers never had this trouble because the boost is tied directly to engine speed. Most turbos today don't accept much lag, and then the playing field has been leveled between the 2 technologies.

This animation is clearly shows how a screw compressor supercharger works. This is the aforementioned style of supercharger used on today'southward 650-hp Corvette ZO6.

Air-cooled engines, like those in onetime VW Beetles or pre-1999 Porsche 911s, were rare even dorsum in the 1930s and 1940s. Like today, nigh cars were water-cooled. This 1936 film begins with a dramatic introduction to the value of a water male child to difficult workers in the field. It'south peradventure the most cinematic 3 minutes in any car tech film I've ever seen. Simply as the story progresses, at that place's a very straightforward animation of how exactly water circulates from the radiator through an engine and back to the radiator. Despite similarities to the systems we employ today, cars from that time routinely overheated—a trouble modern cars rarely suffer from.

Differentials help recoup for the differences in wheel speed betwixt the inside and outside wheels in a corner. Those exterior wheels need to spin more than apace, so without a differential, the tires would scrub, chirp, and wear prematurely—and the drivetrain could sustain impairment.

This video from Toyota illustrates exactly how power flows in a rear-wheel bulldoze truck, from the driveshaft to the rear differential and out to the wheels. Information technology also explains what differential gear ratios are and the types of differentials are bachelor.

17 Clutch-type limited-slip differential

Almost cars and trucks have an "open" style of differential driving the wheels. They operate smoothly, but take a major drawback: When the road is slick (or the dirt trail is muddy), an open diff volition ship ability to the wheel with the to the lowest degree traction. That normally leaves the vehicle motionless with one tire spinning uselessly. A limited-slip differential sends some of that torque to the wheel that has traction.

18 Torsen torque-sensing differential

Many original Hummer H1s came fitted from the factory with a version of the Torsen in both the front and rear differentials. And for many years, a Torsen was the center differential in Audi'south all-cycle drive, significant Audi'southward famous Quattro organisation had this differential to thank for its reputation for peachy traction.

A Torsen differential uses gears instead of clutch packs to divert torque across an axle. The upside is that when it "senses" a torque difference, it works nearly instantaneously, sending torque where information technology tin can be almost benign. The downside? It needs to sense some sort of resistance or friction. So when a tire is off the footing, the Torsen cannot send power across the beam.

xix Springs, shocks, steering and ventilation systems

This vintage clip (though information technology may reek of 1950s sexism) does do an excellent job of showing how some complex automotive systems worked on the new 1950s Chevy models, using easy-to-sympathise models and animations. Chevy customers at that time were plain more than concerned with ride quality than anything else. Today's cars, for the most office, all ride smoothly. If a picture show like that were made today, it would likely focus on efficiency, connectivity, and safety technologies.

It's non uncommon that when a car hits that giant pothole just right, it could begin pulling slightly to the left or right. So automakers build in a level of adaptability into the steering and suspension. This video shows but what these alignment points are, what components they touch on, and how they control vehicle behavior.

Although this is a Jeep-branded animation, the basics are the same for every old-school iv-bike drive system. Engine ability goes to the transmission and then on to a transfer instance. When 4WD is selected, the transfer case splits that power equally between the front and rear axles. Shift into Low Range and the vehicle's torque is filtered through another set of gears. In this case, it's a very aggressive 4:1 ratio. This ultra-low gearing allows the Jeep Wrangler Rubicon to crawl slowly and easily over rough terrain.

Typical hybrids use a conventional gasoline or diesel engine paired with an electric motor to drive the wheels. Energy from an on-board battery pack supplies the power for the electric motor or motors. When the bombardment pack is fully charged (through regenerative braking), hybrids can run on some efficient combination of engine and electric power. And well-nigh can run on pure electric ability for a short time, which boosts fuel economy. Newer hybrids have larger battery packs that tin can exist plugged in (PHEVs), allowing owners bulldoze further on electrical ability and utilise even less fuel. Hither'southward a adequately simple explanation of how information technology all works on a Toyota.

Anti-lock brake systems (ABS) are one of the greatest advancements in automotive safety. Before ABS, a commuter in a panic often slammed on the brakes and locked them up, causing a skid. That's why driving schools would teach students to pump the restriction pedal apace. ABS uses an on board reckoner, hydraulic pump and valves and sensors to proceed the brakes from locking upwardly. Then when the driver panic-brakes and pushes the pedal to the flooring, ABS essentially pumps the brakes for you lot, and far quicker than you could always do on your own. Here's how it works.

Engineers tap into the hardware of ABS to create traction and stability controls. Stability control systems utilise a calculator and sensors to apply the brakes at individual wheels if slipping is detected. Equally a auto begins to slide, say on an icy road, stability control can apply the braking system to correct that slide and go on the automobile on its intended path. Stability control cannot overcome the laws of physics, but the technology has led to a serious reduction in accidents. Here's a cool blitheness from automotive supplier Bosch.

There was a time when power steering wasn't the norm on cars. Early cars and trucks had skinny wheels and tires that were easier to plough, and the vehicles were relatively low-cal, too. Just that shortly changed. The starting time hydraulic steering system on a production passenger auto came in the 1950s, when cars began to really gain weight and tire size. In the mid 50s, the technology came to big, heavyweight military trucks. This caption may be a bit dry, just information technology'll evidence you how hydraulic power steering works in great detail.
