Escape angle • Fall • Convergence ⚙️ Vrom.ro

You asked for your problem What is the angle of escape, How can it be regulated, where it is done and, perhaps, how much does it cost? In this case, read to discover everything you are interested, directly by the specialists.

The angle of escape: what is it?

The flight angle is a name used by mechanics. This term refers to the geometry of the management orientation mechanism.

Guide geometry has three corners:

The convergence angle

• It defines the position of the steering wheels at rest seen from above.
• The wheels are not parallel and the convergence angle is made by the extension of the axes.
• This corner is required in the corners.

The fall angle

• The position of the steering wheels observed in the front or rear – the fall angle is formed by the axis of the vertical wheel.

The angle of escape

• It is visible when we look at the guide wheel on the side.
• It is measured in degrees between the pin axis and a perpendicular to the ground.
• If the flight angle is negative, then the car has a light and unsafe direction (the car runs slightly to the left – on the right: hence the name of escape angle).
• If the corner is positive, the car has a right trajectory.

Price that regulates the angle of escape

The flight angle adjustment prices differ from one service station to another. The differences are generally provided by applied technology, as well as other adjustments that can occur during the course. Sometimes even the vehicle brand can contribute to the price setting.

For example, the price for the adjustment of the flight angle, only on the front, for a logan can be 80. At the same time, for a Mercedes reaches 150 she. It also depends on the number of adjustments that can occur or on the time necessary to perform them.

When is the corner of the flight?

When you feel strong vibrations in the steering wheel, accompanied by non -compliance with the direction of the car (the car pulls on one side), the regulation of the geometry of the wheel is essential.

The «geometry of the wheels» is a common term, which drivers usually replace with the idea of ​​»alignment».

The flight angle is corrected together with the entire geometry of the wheels. If the three corners are not in contrast, then and the wheels suffer because they are instruments in a non -uniform way, leading to their much faster and dangerous deterioration.

When do you adapt the angle of escape? The most common cases are as follows:

• The car is managed with difficulty.
• The wear of the tires is visible and irregular.
• There is a potential insufficient maneuverability.
• Lack of stability.
• Increase in fuel consumption.
• Additional braking.
• DERAP when cornering.

The regulation of the geometry of the wheel is also required in the following cases:

• After repairing the frame, respectively with the replacement of the suspension arms, the spherical joints, the pendulum lever and the tips of the steering.
• After carrying out the works relating to the ruling height regulation: by mounting the distances, the replacement of the shock absorbers or springs with the longer or shorter ones, depending on the situation.
• After changing the car wheels. The control of the alignment of the wheels is particularly important if the tires have been kept inappropriately (stretched on one side).
• After hitting an obstacle or following an accident.
• After purchasing a used vehicle.

Where is the angle of escape?

The management adjustment and the escape angle is performed in specialized service units, by specialists. They use the right equipment, which have the opportunity to adjust all three corners so that the car can have right behavior and can take fairs without events. The adaptation of the escape angle at home is totally contraindicated.

Disturbed angle symptoms

In violation of the parameters of the flight angle it is easy to recognize, if you consider the following symptoms:

• The car runs to the side, the steering wheel vibrates when the car moves in a straight line.
• The car does not keep the road, which is why you have to keep the steering wheel.
• On the slippery road, the car slipped not controlled.
• The reaction behind the wheel is slow.
• The tires are quickly worn out.
• The steering wheel no longer returns to the initial position.

As you can see, the violation of the geometry of the wheels negatively affects the maneuverability and the stability of the vehicle on the road.

Fall corner: What is it?

The car has no perfectly vertical wheels. They have a vertical inclination and the angle formed by the axis of the vertical wheel is called falling angle.

When this corner is too large, the irregular wear of the wheels appears.

The fall angle can be:

• Positive – When the upper part of the wheel is slightly included towards the outside of the car. If this is too large, it appears on the external parts of the tires.
• Negative – When the upper part of the wheel is slightly included inside the car. A negative corner too large leads to cutting inside the wheels.

Adjustment of the corner of front/rear fall

The alignment of the wheels has stopped being a problem for drivers. Almost every service station has adjustment equipment.

The modern stands on which they regulate are of different types:

• With laser.
• Calculator.
• Optics.

These equipment offer quick and precise adjustment of the corners, in a few minutes.

There are also older methods, practiced by some old fashion mechanics. These involve the use of a telescopic rule and a lead.

All operations are performed in a garage, which saves money and nerves. The disadvantage is a large measurement error (1 mm) between direction and another.

When is the fall angle made?

The falling angle must be adjusted when cutting the wheels inside or outside is evident.

However, this is not the only sign of alarm. For this reason, specialists recommend that you present you in a director regulatory center and in one of the following situations:

• When you hit the wheel for a hard obstacle.
• When the tires are very worn.
• When the car has a tendency to move laterally during the walk on a dry road.
• When after the turn the steering wheel does not reposition.
• When you have made repairs to the transmission or management.
• When replacing the tires with some used.

Where is the fall angle made?

As I specified, the adjustment of the fall angle is carried out in a service center authorized by specialists in the diagnosis and regulation of the management.

Symptoms of the fall corner

The negative values ​​of the fall angle reduce the stability of the car, when driving on the right path. However, pay attention to the fact that they tend to improve in turn.

With positive positive values, the opposite is true: it moves well in a straight line, but skin.

How much does the corner fit?

As in the case of adjustment of the flight angle, the price for the adjustment of the fall corner varies according to several factors. Generic, the average value is between 100-200 she.

However, keep in mind that the geometry of the wheels will not be necessary a single adjustment.

Convergence corner: what is it?

The convergence angle is the angle formed between the direction of the movement and the rotation plane of the wheel. Very often there is talk of the total convergence of two wheels on the same axis. In some converging machines it can be regulated by the front and rear.

The convergence regulated incorrectly is the main cause (but not the only one) of the accelerated wear of the tires. With a convergence of 5 mm or more, the tire will be completely canceled in less than 1000 km.

Regulation of the convergence angle

Of all the corners mentioned, this is the only one that can be regulated without the need for special auxiliary devices.

And this time we can talk about a positive convergence corner: when there is greater closeness to the previous parts of the wheels. The car does not become satisfactory and the tires will be cut.

In the case of a negative convergence angle, the proximity is greater in the rear parts. Consequently you will see an overview in the curves and wear between the interior outwards.

When is the convergence corner made?

Producers’ recommendations for installation of wheels should be taken into consideration with responsibility. For each model, the recommendations differ. The regulation of these corners offers the best stability and performance of maneuverability, as well as minimum wear of tires.

Periodically, during the operation of a car (after 30,000 km, it is useful to make a revision of these wheels alignment angles. Furthermore, if on the car, individual suspension elements have been replaced or this has undergone a greater impact, then it is essential to present itself to a service to perform the operation.

It should be known that the adjustment of the corners of the directional wheels is the final operation of the repair of suspension, frame and management.

Where is the convergence angle produced?

The convergence is regulated in authorized service centers, on special equipment, where corners must correspond to standard shares.

• fall corner 0 ° ± 30 ‘.
• Convergence 0 ° 00 ‘± 10’ (0 ± 1 mm).
• Rotation angle 1 ° 30 ‘± 30’.

The corners of alignment of the vehicle wheels in the travel order:

• The fall angle 0 ° 30 ‘± 30’.
• Convergence 0 ° 15 ‘± 10’ (1.5 ± 1 mm).
• Rotation corner 0 ° 20 ‘± 30’.

Symptoms of the convergence angle

There are two types of convergence as I have already said: positive and negative.

It is easy to determine: it is necessary to draw two straight lines along the car wheels.

If these lines intersect in front of the car, the convergence is positive and if they intersect in the rear, it is negative.

In the situation in which convergence is positive, so the car enters the shift and also acquires further women. In addition, it will be more stable when driving in a straight line.

In the opposite situation, in which convergence is negative, therefore the car moves inappropriately, on the one hand and on the other.

How much does the convergence corner cost?

The price differs according to the vehicle. The geometry on the face costs between 95-125 she, while on the back it is about 80-95 she.

For SUV /vehicles, the alignment of the front wheel costs about 150-160 she and on the back 80-100 she.

Specialist advice:

Also check a new car. Purchase of a car from the showroom, receive a car with all the necessary settings. But after a time there is a reduction by performing all the parts, from which these corners are changed.

In the case of repair or replacement of the suspension elements, it is recommended to check and adjust the geometry of the wheels. The only thing that does not affect this parameter is the installation of new stabilizers.

A change in the geomerry of the wheel occurs when the wheels are hit as high edges or are exceeded certain pits.
