All-wheel drive cars have a special transmission design, in which all the wheels are connected to the engine.
This increases the passability of the car, but at the same time makes its control more difficult.
Features of all-wheel drive vehicles
A four-wheel drive vehicle is called transportMeans with such a transmission mechanism, which allows to transfer the engine torque to all wheels. Simply put, in an all-wheel drive car, all four wheels are connected to the engine, so that they spin and drive the vehicle. There are also front-wheel and rear-wheel drive cars, in which the front or rear wheels spin, respectively, and the other two only rotate in the course of the car.
Initially, cars with four-wheel driveWere designed as off-road cars, but today they are widely distributed on domestic and foreign roads. In addition to high cross-country ability in various weather and relief conditions, such cars have a number of disadvantages:
- complexity in management-
- the high price of the car-
- high fuel consumption.
Complexity in management is characterized by the presenceVarious variants of implementations of the all-wheel drive: permanent all-wheel drive, manually-connected four-wheel drive, automatically connected all-wheel drive. Each of the transmission schemes has its own control features, which can be difficult to apply under extreme conditions.
Predominantly the acquisition of cars withAll-wheel drive transmission is associated with a hobby or driver's work, where there is a need for increased patency of transport. Class of all-wheel drive vehicles are VAZ-2121 "Niva", UAZ, SUVs. All-wheel drive vehicles make up to 10% of the model range of almost every car manufacturer.
Popular transmissions - with rear and front-wheel drive
In driving a rear-wheel drive carIt is necessary to pay special attention to the accuracy and speed of the steering and accuracy in the handling of the gas pedal. Sharp and too strong movements of the steering wheel and the accelerator pedal can cause the car to drift, especially on slippery roads. The movement is stabilized if the gas pedal is smoothly thrown off.
Rear-wheel drive cars are represented by models VAZ-2101-07, Moskvich-2140, Volga, Mercedes, BMW.
Cars with front-drive transmission schemeAre dynamically stable. They are less agile, less maneuverable than rear-wheel drive, resistant to drifts. The downside of such cars is their stability with linear motion on any surface. This means that the driver feels weak that the road may be slippery, and when turning the car, it can tear down.
Represent a class of front-wheel drive cars such as VAZ-2108-15, Moskvich-2141, Volkswagen, Audi, Opel, Nissan, Ford, Toyota, Honda, Volvo.
