4.04.2017

In 1996, the release of the car Kia Sportyj began. At that time in model row The brands did not have such machines, and the crossover market, in fact, did not exist. However, the company has already clearly felt new trends that began to influence the automotive industry in Europe and Asia. Due to the rapid development of world car industry, the high continuity of brands and the transition of cars in a wide mainstream, demand conjuncture changed, the need to introduce a new type passenger carswhich would satisfy earlier seemed incompatible requirements. Large and powerful all-wheel drive SUVs were roads in operation and maintenance. Their use for personal goals, especially in cities, turned out to be uncomfortable. The class of sedans and universal possessed limited features For spaciousness and pavement in areas with imperfect road surface and volatile weather conditions. Against this background, Kia's specialists decided to take part of the emerging and, as it turned out, a very promising niche, creating a modern capacious car With good handling, comfort level, high ground clearance and, most importantly, full-wheel drive.

Kia Sportage 2017 with full drive and diesel engine 2.0 CRDI

First generation

Kia Sportage of the first generation was still under the influence of the peculiarities that the SUVs of a more utilitarian class possess the framework of the body, in its running part and the transmission, some decisions were prevented from those who were his predecessor. But with the drive system, it was necessary to solve something. Constant four-wheel drive For all four wheels for Sportage, it was no longer needed, since there was not so much permeability into priority as the balance of opportunities, convenience and economy. Therefore, the crossover drive was implemented according to the part-time system. In this drive design rear axle Connected constantly, and front can be connected temporarily if necessary. Kia Sportage 1 with this type of full drive showed itself on a light off-road, possessed a low fuel consumption and decent handling despite the high clearance. Due to enough soft suspension In the conditions of the city, the crossover possessed a good level of comfort. The disadvantages include:

• PART-TIME system feature - you can not move along dry and solid coating in the full drive mode;
• The low reliability of the hubs of the front wheels, they sometimes fail front-wheel drive ceases to turn on;
• The need to connect the front-wheel drive in manual mode;
• Lack of locks, which reduces the possibilities of the car on off-road;

New cars Kia Sportyj are equipped with a modern all-wheel drive system called Dynamax. This advanced installation automatically traces and analyzes driving conditions, predicting the requirements for drives. The transmission of the car is configured in advance, depending on the complexity of the road surface. A four-wheel drive at Kia Sportage is different from other systems that react to the conditions that have already developed. Let's figure out how a four-wheel drive works at Kia Sportage.

The Dynamax setting consists of an intelligent control unit that is constantly analyzing the data coming from controllers. The block adjusts the torque using the coupling of the electro-hydraulic structure. Application at Kia Sporty new system Dynamax made it possible to make the process of changing the car's work, depending on the road surfaces, intuitive and transparent.

The crossovers of this model with full drive are manufactured both with gasoline and with diesel engine. If we consider in detail how a full-wheel drive is working on Kia, to start learning the system from the electronic unit located on the panel from the left side under the facing material. The block collects data, including information about the current load on the motor (sensor throttle valve), the frequency of rotation of all the wheels of the car, the degree rotation of the wheels. Also the electronic unit Gets information from the block that is responsible for the anti-lock system. Rear-wheel drive in Kia Sportage is connected by means of an electromagnetic clutch, located in front of the rear axle differential.

IN this car There are two all-wheel drive modes consisting of an automatic version and blocking mode. With automatic mode, the rear axle is connected only if the ECU is needed. While riding on a normal road, Kia Sportyj works like a classic front-wheel drive car. The special switch activates the lock mode. The button, depending on the year of release of the car, is located on the control panel, to the left of the steering wheel, or in the center of the central tunnel, near the gear lever.

When at Kia Sportage turns on the constant four-wheel drive, the warning lamp on dashboard lights up orange. Lock mode transmits half of the torque on rear wheels. Its inclusion is possible at a speed not exceeding forty kilometers per hour. When the car begins to go with a speed of thirty kilometers per hour, there is a phased shutdown of the rear axle. With an increase in speed, not ten kilometers, the rear axle turns off completely.

When the speed decreases, the same process occurs in the reverse order. In the speed range from forty to thirty kilometers per hour, torque transmitted to rear axle, increases to the power on the full drive. Deactivation of the locking mode is performed by re-pressing the button.

On the instrument panel screen Kia Sportage, not only the control lamp, indicating the transition to the lock mode, but also a sensor that signals the presence of problems in the nodes of the all-wheel drive system. If there is a breakdown, a red light will turn around.

On the models Kia. Sportage contains 4WD system, consisting of a handouting box, a cardan shaft and an electromagnetic clutch. In such a system, the torque is distributed between the axes with the help of an electromagnetic coupling on which transfer case Transfers rotation by means of a cardan shaft.

Consist of outer 2 (Fig. 1) and internal 7 hinges of equal corner speeds (Sls) connected by shafts of drives 6 and 9.

Fig.1. Drives of the front wheels of the car Kia Rio.: 1-specifying ring of rotational speed sensor; 2- outer hinge of equal angular velocities; 3- large hinge cover clamp; 4th hinge case; 5- Small hint hint fastening clamp; 6 - the actuator shaft of the right front wheel; 7 - internal hinge of equal angular velocities; 8-stop ring; 9 - the actuator of the left front wheel; 10- Dynamic damper.

Outer hinge Provides the possibility of only the angular movements of the connected shafts. Internal hinge additionally to the corner provides axial shifts of shafts when turning the front wheels and the operation of the suspension. On the exterior hinge body, a specifying wheel of the wheel of the wheel rotation frequency sensor is pressed.

Birfield Outer hinge consists of a housing, separator, closure and six balls. In the hinge body and in the cable, grooves are made to accommodate balls. In the longitudinal plane, the grooves are made along the radius, which provides the desired angle of rotation of the outer hinge. The slot tip of the exterior hinge body is set in the hub of the front wheel and is attached to her nut.

Outdoor hinge rope is installed on the shaft slots and fixed on the shaft by a locking ring.

Internal hinge The drive of the front wheel type tripod consists of a housing and three rollers on needle bearings, attached to the trunky hub. In the hinge case, grooves are made for rollers. The three-sized hub is fixed on the shaft of the locking ring. Rollers allow the hub to move in the grooves of the hinge housing in the axial direction, so that the drive can be lengthened or shortening to compensate for the mutual movements of the suspension and power aggregate. The tip of the housing of the internal hinge with the outer slots is fixed in the semi-axle gear gearbox with a spring retaining ring installed in the shaft flow.

In the outer hinge, the balls of one sorting group are installed. All the details of the hinge are selectively selected to each other, so it is impossible to repair the hinge of the individual details. The spare parts supply only a hinge assembly, as well as a small Remkomplekt, consisting of a locking ring, cover, cover clamp clamps and in some cases lubrication.

The internal hinge is supplied to spare parts in the form of repair kits: a large, including all the details of the hinge, and a small, similar to a remaxer of the outer hinge.

For lubrication of hinges, a special lubricant with disulfide molybdenum is applied ( domestic analog - Shrus-4). The cavities of all hinges are protected from road dirt and water to rubber corrugated covers 4, fixed on hinges and drive shafts, respectively, large 3 and small 5 clamps.

Shaft drives differ in length, therefore the drives of the right and left wheels are non-violent. To reduce the vibration in the transmission on the shaft of the right drive, a dynamic damper 10 was installed, fixed by a clamp, similar to small clamps 5 covers 4.

HELPFUL ADVICE:

Hinges drives are very durable, their settlement resource is almost equal to the resource of the car. However, they change them or repaired quite often due to damage to protective covers. Such work is dear and time-consuming. To save seriously, regularly check the condition of the protective covers of hinges and immediately replace them with the slightest damage. If water or dust falls into the hinge through a damaged case, it will fail after a few hundred kilometers of the mileage. The hermetic hinge is wondering extremely slowly.
