Many car owners think that they never have to face such a problem in life as replacing the steering wheel in the car - this node seems unshakable and reliable. But often there are often malfunctions associated with wear of fasteners, bearing or electronic components that are installed inside the steering wheel. In addition, many motorists change the steering wheel on a non-standard product in order to increase the comfort of vehicle or improving manageability. One way or another, the replacement of the steering wheel is a rather difficult event. To prevent breakdowns and do everything correctly, you need to accurately follow the instructions. About this further in the article.

Auto-power - device, principle of operation

Steering of a modern car with a hydraulic agent:

Steering Tower (1), longitudinal steering (2), steering mechanism (3), suction hose (4), drain hose (5), tank (6), right side steering (7), right pendulum lever (8) , cross steering (9), steering (10) entrance shaft (10), bottom cardan hinge (11), cardan shaft (12), top cardan hinge (13), shaft steering column (14), steering wheel (15), left Pendulator lever (16), left side traction tip (17), tip of the adjusting tube (18), left lever steering trapezium (19), hinge cover (20), tip left side traction (21), hinge (22), discharge hose (23), hydraulic power pump (24).

Most modern cars are equipped with steering amplifiers - electrical or hydraulic. The steering wheel amplifier is designed for comfortable control of the vehicle, as well as to reduce the effort on the steering wheel and hold the car after a sharp maneuver. The steering amplifier enters the basic configuration of almost every modern car.

The basis of the steering is the steering mechanism that performs the following functions:

• Spontaneously returns the steering wheel into a neutral position in the removal conditions.
• Transfers the force steering wheel.
• Increases the effort attached to the steering wheel.

Actually, the steering mechanism is a gearbox (mechanical transmission), therefore its main parameter is a gear ratio. Depending on the type of mechanical gear, there are such types of steering mechanisms: screw, worm, wheels.

Consider the principle of operation of the roll steering mechanism (it is most often installed on passenger cars): when rotating the steering wheel, the rail moves to the left or right, and while the rail drive attached to it is moving to it, which rotate the controlled wheels.

Constructive features of the author

The roll steering mechanism is characterized by simplicity of design, respectively, high efficiency, as well as high rigidity. However, along with this, this type of steering mechanism prone to vibrations and sensitive to shock loads from irregularities on the roads. Due to the peculiarities of its design, the roll steering mechanism is mounted on cars with front-wheel drive and independent suspension controlled wheels.

The screw steering mechanism consists of such structural elements: steering thawed on the shaft of the sector, screw on the steering shaft, nut, moving along the screw, gear rail, sliced \u200b\u200bon the nut, and the toothed sector, which is connected to the rail. The peculiarity of the screw mechanism is the connection of the nut and the screw with the help of balls, which makes it possible to achieve smaller friction and pair wear. This type of steering mechanism is mounted on some executive class cars, heavy trucks and buses.

The worm wheel mechanism combines the following structural components: a global worm (worm with variable diameter) connected to a steering shaft, and a roller. The roller shaft outside the wheel of the steering mechanism is mounted, the lever (tha), which is associated with the steering rods. The worm steering mechanism is less sensitive to shock loads and provides better car maneuverability. But it is expensive due to the complexity in the manufacture. Steering with a similar mechanism has a large number of compounds, therefore requires systematic adjustment.

The worm wheel mechanism is used on passenger transport with increased patency and dependent suspension, easy cargo transport and buses. Previously, this type of steering mechanism was mounted on the "domestic" classic.

For all models of steering, common design features are characteristic:

1. In the middle of the steering wheel, there is a hub in its inside, with which this device is attached to the steering column.
2. External rim - managing part of the entire device. The driver keeps precisely for him and, affecting the external rim, transmits the torque of the steering column, and through it - right on the steering thrust.
3. The hub and the external rim are connected with the help of spokes that may look like a pin or plates, and four, three or two there are them.

Steering wheel, from what depends the size of the steering wheel

The size of the steering wheel installed on the vehicle is substantially depends on whether the hydraulic hydraulic is mounted or an electric steering amplifier. In addition, the steering wheel size largely depends on the effort on it. There are certain requirements for limiting effort on the steering wheel in an amplifier failure. The torque that is required to rotate the steering shaft is equal to the work of the force (which the motorist is attached) on the shoulder (radius of the steering wheel). Therefore, the smaller the steering wheel, the more difficult it will turn it. The buses and trucks are heavier to rotate the wheels, so the steering wheel is large and costs more horizontally. In passenger cars, it can be done less.

The modern steering wheel of a modern car, which is derived to the steering wheel

On the modern steering wheels of many cars, the control buttons are displayed from various car systems. An integral attribute of this device is a beep, differently only placing the control of this signal. In fact, in all models of cars, the switches of turns, switching of wipers and light are mounted with the wheel. Therefore, when replacing the steering wheel, there is a need for dismantling and data of accessories. It is worth noting that in old models of vehicles, especially American, actually right in the steering wheel, the gear lever was installed.

In addition, in our time there are so-called multifunctional steering wheels (multi-steering wheel), which can display the audio system, telephone, onboard computer, navigation system, voice control system, cruise control, air recycling.

How to buy a new steering wheel to pay attention to

Before changing the steering wheel, the car owner should seriously think what type of steering wheel is needed. Many drivers prefer sporting rugs. Of course, the appearance of a similar device attracts attention. Thickened, small in diameter, with curly excavations that make the capture of the steering wheel comfortable. Most often, it is made of elastic materials and pleasant to the touch. Nevertheless, this is not always a wise decision.

By car without a hydraulic device while driving around the city most conveniently use the steering wheel of a large diameter. As mentioned above, rotating such a steering wheel, the motorist has to make much less effort when making a complex maneuver.

In addition, there is an important condition that should be observed when purchasing a new steering wheel. You need to check the place where the new device is attached to the vehicle steering column on which the steering wheel is replaced. This design is not rarely manufactured only for a specific vehicle model and does not have a unified compound.

As for cars with multifunctional steering wheels, which are mentioned above, only unique devices are suitable for them, since it is very difficult to redo the control circuit of the automotive systems. When choosing a new steering wheel, it should be represented as well as convenient it will be located in the cabin and will not be a driver of a hindrance. The perfect option is the selection of the steering wheel on the manufacturer's recommendation - such steering wheel have compliance certificates and have the corresponding marks on the package.

Choosing a workplace

All work on the replacement of the steering wheel should be carried out on a flat horizontal surface. The vehicle, while fixed with the help of a manual brake and the first transmission turned on when the motor is not working.

Safety technique

For insurance under the wheels it is better to install mechanical stops. In mandatory de-erase automotive systems, removing the terminal with the battery.

Tools, fixtures, consumables

1. Cross and flat screwdriver.
2. Spanners.
3. Mechanical stops.
4. Gorotok for the central nut.
5. Directly steering wheel itself.

Preparatory work (step by step)

• First of all, it is necessary to dismantle the outer coil of the steering wheel, under which the electronics, fastening and airbag unit are located. It is necessary to do everything extremely gently, as the risk of damage to important elements of the steering wheel is quite large. For this event, a flat screwdriver is used, with which you need to pose fasteners of the casing.
  
• Now you will see in front of yourself "insides" of the steering wheel - the first thing is neatly retrieved airbags and block blocks that should be put aside.
• Then take the cross screwdriver and dismantle the electrical contacts from the steering wheel - you turn on the wiring of ordinary pieces for entries so that you do not confuse them when replacing them.

How to remove the steering wheel and install a new one (step by step)

1. To replace the steering wheel, it is successful, it is necessary to check it for the presence of clamps - for this, you must inspect the back side of the hub using the mirror or make a photo using the phone. As a rule, they are represented by insignificant thickens of the steering wheel shaft with slots, which are open in the extreme position.
2. If there are clamps, you need to remove them alternately, for which the steering wheel turns to the left and right, respectively, and then screwdriver in the mentioned holes. Slightly by clicking on it, you will hear a click, and you will also feel that a small space has arisen between the steering column and the steering wheel.
   
3. Having done such an event with the second retainer, proceed to the dismantling of the central nut.
4. Such a procedure is carried out, as a rule, with a turn with a head M12, since the nut is often recessed quite deeply into the cavity of the steering wheel. In the process of dismantling the nut with one hand, you need to hold the steering wheel, without letting it be able to rotate freely.
   
5. When the process is over, we carefully pull the steering wheel, controlling the procedure with a look at the side.
6. When replacing the steering wheel, it is extremely important not to damage the electrical contacts and wires - you will have to monitor their tension.
7. Carefully release the tensioning wires, and then finally remove the old steering wheel.
8. If you need to use an adapter to replace the steering wheel, then you should start from its installation. Carefully check how tightly the detail sits on the shaft, and only then put on it the steering wheel.
   
9. Lowering the steering wheel to approximately the middle, the sale of the wires through special holes and try not to damage them by mounting a new steering wheel in place.
10. After that, we collect everything in the reverse order - this step of replacing the steering wheel begins with connecting electrical contacts to sensors and buttons. When everything is ready, mount the signal blocks and airbags.
11. When you double the integrity of the wires and tighten all the connections, you can mount the casing - replacing the steering wheel is completed.

Council Prof.

At the last stage, it should be verified for which it is necessary to shift the steering wheel to the side and pull it on. In addition, it should be carefully listened to its feelings when driving the first few kilometers. If you notice that installed the steering wheel is incorrect, contact the service center immediately, to avoid problems in the future.

At first glance, there is nothing complicated. But it is worth starting the procedure for replacing the steering wheel to understand that each action requires accuracy and attentiveness. The entire procedure for experienced masters takes no less than an hour, and unprepared beginners can spend on it up to several hours.
