What is the purpose of the main sites of mechanisms units of the automobile?

We are accustomed to seeing cars that include 4 wheels, placed on the corners of a triangle. Even impossible to imagine that once the cars had a larger number of wheels. For example, experimental models have been created with 6 or 8 wheels. One such model, where the diamond-shaped arrangement of wheels - one wheel, front and rear, located in the center, and 2 sides. Here only those options too - it came to there the cars. But let's still talk about conventional cars, where the number of wheels does not exceed four. From this article you can learn how the appointment of the principal sites of mechanisms units of the automobile, their location, as well as directions for use. Accommodation steering wheel Many of the cars is a front, ie driven wheels are on the front of the car. When in a car driven wheels are located on the rear axle, its handling improved in some cases: At high speeds the rear wheels rotate synchronously with the front, but at a smaller angle - develops protivozanosnye properties; At the same low-speed rear wheels rotate in the opposite direction relative to the front - This enhances maneuverability. Also make all-wheel drive vehicles, such as SUVs or ATVs. Such control allows the vehicle wheels to prevent skids on the road. If sued, then when you turn the rear wheels on one corner to the front, but in the opposite direction, it would be reasonable. But such a scheme is unlikely to be suitable for good driving, to avoid the incident, such a scheme is used on slow moving vehicles (forklifts). Next, we consider each option separately. Classics of the genre (rear-drive vehicle location units) In this arrangement the main vehicle components are located in the following order: the engine took its place in front of the car (under the hood), the driving wheels, respectively, in the back. Auto Salon is located inside the wheelbase, the rear - trunk. Due to this separation transmission takes a simple form. The weight of the car is distributed evenly between the axles, but when you go uphill or develop greater speed increases the load on the rear axle - this is a win-win situation for the ride quality. But, as always, no minuses in any way - propeller shaft and rear axle is a certain part of space from the passenger compartment and trunk. Length (extension) transmission gives it more weight and improves the degree of vibration in the cabin. Once upon a time, this classic layout is one of the most profitable, but now its trying to get round. To date, most have placed the engine within the wheelbase, and to make the gearbox to the rear axle to improve weight distribution. Council under the skidding car: steering wheel to rotate in the direction of the skid, do not brake and do not squeeze the grip, increase fuel supply. The front-wheel assembly mechanisms cars in front wheel drive car engine, combined with the transmission in a single compact unit, and the driving wheels are in front. This location gives a great advantage: the lack of rear axle provides a more spacious luggage contents. Just cars this configuration is less susceptible to drift than zadneprivodnye. Here, transmission is more complicated because there is a need to transfer the rotation to the driven wheels. Ie when driving uphill and acceleration unloads the front axle, which contributes to the need for the distribution of vehicle weight in favor of the front axle to avoid slipping. Currently, this layout mechanisms used in all classes of cars, though earlier it was meant only for small cars. Council under the skidding car: fast, but gradually turn the wheel in the opposite direction of the skid, do not brake and do not squeeze the clutch, stopping the fuel supply. Full-drive layout of the main nodes in this layout engine can be located in three areas - front (such as Audi, Subaru), rear (Porsche and other sports cars), and the center (Lamborghini, Tommy Kaira). All wheel drive. Driving performance and throughput of these vehicles exceeded, because transmission is the most complex and difficult. So cars are inherent in transmission losses and negative impact on the passenger compartment and trunk. Tips for drift car: Do not let go and not press on the gas pedal, stepped on the gas if your car has not lost his grip. Rear-engine layout of the car combined with the transmission in a compact unit, with the leading and trailing wheels are separated, which facilitates primitivization design. This engine and drive wheels are located behind. The trunk is very small, because located in the front car, and most of it occupied a niche driven front wheels. Patency of such cars is increasing, but the level of drift increases, because all part of the burden falls on the rear axle. These rear-engined cars are available only auto manufacturer Porsche (Porsche). Tips for drift: Push the brake pedal with the same intensity as the degree of drift (ie the quality of adhesion to the road wheels) Do not turn the steering wheel in the direction of the skid. Mid-motor layout engine units located behind, but before the rear axle. This facilitates load balancing on two of the car. In addition, the reduced moment of inertia of rotating around a vertical axis, which improves maneuverability. This layout of the main units and mechanisms used in the manufacture of sports cars (two passengers), as this engine layout is a huge space in the cabin, as well as for racing cars (eg Formula 1 cars). If on minivans engine with horizontal cylinders located under the cabin, then this car may also be considered mid-motor layout.
