Another difficult repair truck frame fell to the lot of our "surgeons".

Repair frames trucks and trailers

The frame is load bearing element transpotrtnogo means mounted on the frame and body (avtonadstroyka) and the chassis, so the frame has very high standards of safety.

There are two types of deformations of frame:
- natural (during operation of the vehicle);
- artificial (emergency).

Natural strain - it is such a strain frame, which is the operation of the vehicle.

For example: Our company is engaged in manufacturing covers. In some semi-long frame is so weak that the geometry changes after loading frame (frame appears vertical deflection up to 50 mm) and made us a new tent is not suitable (grommets not get on side brackets), since changing the geometry of the framework.

Another example is the natural twisting of the frame:
Everyone knows that the right turn "cooler" of the left (right turn path is less than the trajectory of the left turn), so that on the long side on the vehicle deformation frame to the right. Due to the different trajectories (radius) of the right and left turns are uneven tire wear (the inside of the wheel relative to the outside, the left front wheel, relative to right, especially when turning on the minimum turning radius)..

Here's another example of the natural deformation of the frame - this torsion (screw) of the frame. This car has a mileage of 3000 km, there was no overdrive, but the frame is deformed by 75 mm screw. This frame set only one transverse cross member. The contour of the frame is not closed, that "walk" spars with each other.

Torsion Frame 75 mm

The cause of the natural deformation of the frame is not only metal fatigue over time, but the design flaws:

In the selection of the steel grade;

The thickness and size of the walls, shelves, corbels, Langeron and traverse frame;

Constructive frame (number of cross traverse, their location, how the constituent compounds of the frame);

Saving the factory on materials and labor (for some light-duty trucks do not put stretchers, although the subframe (subframe) and adds strength frame, semi trailers do not strengthen the "goose", etc.);

Universality frame (extendable frame by increasing the individual elements for other frame sizes body).

Just three frames on the factory compound of two meters length

Now consider the artificial (emergency) deformation frame. There are various defects emergency frame:

changing the geometry of the frame (vertical deflection, torsion, lateral deformation, deviation from the vertical position, buhtinovatost, dioganalnoe longitudinal displacement);
fractures of the frame;
cracks, bends;
variation in wall thickness (raznoploskostnost);

Emergency deformation occurs due to several reasons:

motor vehicle accident;
excess of the allowable loads (overload the vehicle);
violation of the rules of operation of the vehicle (non-uniform distribution of the load on the load platform, operation of the vehicle at a faulty coil non-horizontal production truck during unloading);

Truck repair frames - it tives science. This is not the Autobody - a combination of sciences such as strength of materials (resistance mterialov) and metal technology.

Edit and repair the deformed frame - this is a very complex technical process that requires high qualification of specialists in the repair frames.

The company "RADAR" certified repair truck frames and has a wealth of experience in such works. Some examples of our work.
