It was a novelty for the domestic auto industry to use front-wheel drive in the design of cars. But the success of the eights and nines amazed the designers. These cars surpassed the classics in all respects. This applies to comfort, speed and reliability.

Step 1
Front-wheel drive cars at one time gained popularity in our country. When the first eights and nines appeared on the roads, many appreciated them. Of course, they were better than cents and sixes, but these improvements are associated not only with the use of front-wheel drive. It should be borne in mind that the car was completely new for those times. The ignition system, the gas distribution mechanism, the layout of the engine, the design of it and the gearbox, all this was completely new, previously it was not used in the domestic automotive industry. It is also worth paying attention to a more streamlined body shape, a spacious interior, and many more details that improve ride comfort.
Step 2
Front-wheel drive vehicles have both longitudinal and transverse engine locations. The second is most typical for small cars, because the engine and all auxiliary equipment can be placed in a relatively small engine compartment. Of course, the layout is such that there is very little space under the hood, and sometimes there is none at all.
Step 3
The engine transmits torque to the clutch basket, which houses the driven disc. The input shaft of the gearbox is installed on the driven disc. Particular attention should be paid to the design of the gearbox. If we compare it with the gearbox of a rear-wheel drive car, we can see that a gearbox and a drive axle with a differential are combined in one unit. This is quite reasonable, but during repair it causes some difficulties that relate to removing the box, since it weighs a lot.
Step 4
A differential is needed to make the drive wheels rotate at different speeds. If you make a direct transfer of torque when the wheels rotate in the same way, it is impossible to turn on such a car. For example, when turning to the right, the right wheel will rotate more slowly than the left, because the turning radius of the left wheel is larger, its path will be longer.
Step 5
The transmission of motion to the wheels is carried out using CV joints, popularly called them grenades. These are shafts with ball joints at the ends. One limb is installed in the gearbox, and the second in the hub. And the most important thing in front-wheel drive cars is the suspension. As a rule, it is a MacPherson-type suspension. It uses a shock absorber strut that is attached to the body through a thrust bearing. It allows the rack to rotate when pivoting.
Step 6
The rack has a steering knuckle to which the steering link is attached. And from below, the shock absorber strut is mounted on the suspension arm with a ball joint. It is also worth paying attention to the steering. Unlike rear-wheel drive vehicles, a rack is used here, which has greater reliability. A car with a steering rack is much easier to drive. And on the rail, you can easily install both a hydraulic and an electric amplifier.
