The operating conditions of automotive equipment, in particular, cargo semitrailers, on the roads of the former USSR are very significantly different from those in Western Europe, due to which the supporting structures experience significantly greater loads than those for which they are designed. It is also important that a significant part of the fleet of foreign-made semitrailers was purchased after the depletion of its resource on normal roads. Such conditions lead to the fact that welded and fastening joints of structural elements, and often the metal itself, are often destroyed.
increased dynamic loads when driving on uneven roads;
overloading often practiced by drivers (exceeding the rated carrying capacity);
active influence of aggressive media (salts, etc.), leading to accelerated corrosion;
a number of design features;
metal fatigue.
In addition to these natural causes, deformations and other kinds of damage occur as a result of road accidents, from which, unfortunately, no one is immune.
Most often, the negative impact of operating features leads to the following malfunctions:
breakage of the spring bracket (with mechanical suspension) or trailing arm (with pneumatic);
violation of the geometry of the rear gate portal;
detachment of attachment to the frame of the side struts;
cracks in the frame side members;
destruction of the connection of the traverses with the spar;
through corrosion of steel sides and gate leaves;
deformation of the underride guard.
Taking into account the specifics of the operation, quite often welding work on the repair of semi-trailers is carried out outside specialized technical centers - in small workshops, or at the enterprises' own repair base, often using homemade welding equipment.
For the suspension elements to work correctly, it is necessary not only to restore its attachment to the frame, but to achieve an exact correspondence to the previous position. For these purposes, experienced welders first fix the bracket with M16 bolts, thus ensuring accurate centering of the parts and the necessary pressing force of the bracket to the spar, and only then weld it with a continuous seam.
Often, in order to increase the reliability of the connection, additional reinforcing elements are installed from available materials - a corner or another profile.
Even the highest-quality welding is not able to ensure the reliability of the connection of these elements for a long time, due to which, after strengthening the side and rear struts, additional reinforcement is applied using homemade triangular metal parts - the so-called. "Kerchiefs", which are welded with straight sides to the spar and the strut on one or, more often, on both sides. This uncomplicated design greatly increases its rigidity and successfully withstands the inevitable effects of vibrations.
For the same purposes, "kerchiefs" are often strengthened by the racks even on new semitrailers.
An obvious mistake of inexperienced repairmen with such a malfunction is welding along the crack line. Such a solution is completely ineffective, since the weld is the zone of the highest stress concentration, and it breaks easily even under moderate enough loads.
The correct solution is to cut out a diamond-shaped window in place of the crack and insert a plate of the appropriate shape into it, welded with a continuous seam (the so-called "tambourine"); a change in the stress vector makes it possible to increase the strength of the structure many times over. To strengthen the spar in the area of its restoration, usually a plate, corner or channel is welded on top of the beam on "tacks".
Removing a stiffener between the flanges of the spar to install channel No. 22 1.4 m long.
Holes for electric rivets (4 pcs.) And tie bolts M16 (3 pcs.) Installing the beam on the frame:
Vertical installation of three channels # 20, length 336 mm, for tie bolts M16.
Pay attention to the correct techniques for finding suitable materials.
Safety instructions
Mastering the requirements for safety in nature.
Pay attention to the ability and skills to use tools.
To instill in students to nature, mutual understanding with the environment.
Allocation of places, territory, tools and responsibilities.
According to the structure of the program, the program is a table in the form of an algorithm for the teacher's actions to study and instill generalized skills, laid down in slots, where generalized skills are located vertically, tools, equipment and devices, materials are located horizontally.
Reading the algorithms of the teacher's actions for working with the program is simple. The main thing is to understand: which of the skills is being studied for a certain period of time, how to find them when planning the process of action.
Every year, the knowledge of schoolchildren expands and deepens in the calculation of planning, production output, sales and summing up. Thus, economic knowledge is laid down gradually as the generalized skills are mastered and become generalized polytechnical knowledge and skills.
Each of the generalized groups of skills cannot be studied and consolidated by practice separately, they are combined, grouped or studied, formed in combination with other skills, depending on the tools, equipment, devices used and the nature of the types of productive labor performed. The defining beginning of the action is the material with its inherent properties. The form of education from this material prompts actions with it.
Thus, all types of generalized skills are studied, practiced, polished only during the manufacture of a specific product. The product can be very simple or very complex. The complexity of the product design, the many technical and technological solutions and determines the complexity or simplicity, the method or technique of manufacturing. It also suggests what complex of generalized, specific and professional skills the one who decides to do this should possess. In practical work, the student implements those skills that are needed and necessary when performing a technological operation and in general the entire technological process. The nature of this approach is gradual and is ensured as you master the techniques for performing the work.
In a labor training lesson, students gain knowledge in the process of performing direct manual labor and in mastering production technology. It starts with the teacher. He is the organizer of the activities of students to gain knowledge about the methods of acquiring skills, the form of education and changing the type and design of products, the technological process. It is important that schoolchildren, when using hand and power tools, machine tools, know and master them in the process of controlling them, working on them:
workmanship of parts;
what parts they consist of, their connections;
the possibility of replacing others;
safe driving conditions.
The possibility of such achievement of children's learning ability is provided by the student's creative attitude to labor, performing, productive activities in the skillful areas of the teacher, research, studying the approaches of students to their labor and educational activities. Here communication, the teacher's attitude is built on the basis of an explicit (explaining, explaining norms of behavior, cognitively directed) approach.
At the head of the general educational tasks for the development of the system of labor training of schoolchildren during the transition to market relations is the change in the structure of the content of labor training subjects and bringing them in line with the life orientation of graduates of incomplete and complete secondary schools.Now the life orientations of young people have changed in favor of personal interests, the educational policy of the state must take this into account. In this formulation of the issue of education, the orientation of the school curriculum towards satisfying personal interests (only not mercantile), aimed at strengthening the personal function of self-regulation, self-education of the child, also presupposes a change in the content of labor education in accordance with the changing life of society.
The content of the program should set the task of merging the processes of labor and learning within one subject. The unifying functions of these processes are generalized skills that functionally integrate the vision of the mode of action with the mental image of the flow of the technological process and control the mental activity of children during execution, i.e. in the implementation of this task. Thus, the subject of labor training is designed to increase the intellect of the child, to promote the development of mental abilities inherent in nature more effectively, more objectively, more effectively, since the child sees the result of his successes with his eyes, feels with his hands, takes a soul or worries and worries that suddenly his work is not will be confirmed by objective data. Therefore, he searches, investigates in order to find the right action.
Our choice of the object of training coincides with this scheme. In our choice, we put forward in the first place generalized skills as functional features of any technique, technology and proposed the task of mastering these functions. The program posed for the children the problem of mastering generalized skills in the logic of the development of activity as a special tool for the necessary and sufficient provision of opportunities to achieve the goal. The child's thinking should be directed in such a way that the means provided to him decide how best to master the skills and use them to solve other problems.
The preserved traditional methods and techniques are further developed with the introduction of the "Fishing Tackle" circle, which raises the educational process for the labor training of schoolchildren to a higher level in the light of modern requirements.
Thus, for any technique, tool, machine, and above all, the question is posed: cuts, saws, planes, hollows, embroiders, sews, beats. - that is, the definition of the functional purpose of the object through which the generalized polytechnic skill is processed. What corresponds to this or that object? After that, the exploitation of technology, the tool becomes the mechanism through which the mastery of functions - generalized skills - is formed, perfected. Learning in this way shifts back the study of the structure of the technique itself. Its management, as the beginning of the functioning of an object, must be shown reproductively in compliance with safety measures and taking into account the age of the children. Here it is important to know not the details of the object, but to be able to control its functions. Due to such objective reasons, proven and practically confirmed theories of polytechnic knowledge, the principle of the object study scheme was abandoned in the curriculum for the subject of study: device - principle of action - operation - functions.
Providing children with the opportunity to practically solve the problems of labor education will make the subject accessible, make the impossible possible, and far from "goals" - the subject of action. The process of cognition begins with the properties of the material used, the features of the functions of the tools used, etc. To change and obtain a new objective form through action, not simple, but creative. In this regard, it is appropriate to quote the statement of M.N. Skatkin, who, analyzing the function as a teaching tool, writes: “The function has mobility. A function is a specific activity, and an activity is an alternation of realized skills.Function mobility is nothing more than the transfer of skills from one situation to another. "
here is my branch where I repaired the frame.
my car is running on a daily basis now. everything works well there are no comments on the repair of the frame. It's a good idea to wrap the old frame with a new one that fits. you still need to start such a repair with sandblasting god help.
Fig-behold, what frame should you pay attention to? Which one is closer to “us” or which is all in rhombuses? How does Kyzya miss such a thing?

Yes, about ZIL, I'm also interested?
the one that is closer, I sold them a half-cut, they will splic it with their tail (by the way, it is from zil).
and here are the last photos of my zilka
[QUOTE = Dzenz; 1151760895] The frame broke on both sides. Broken at the attachment point of the rear ladders. I was looking for something similar on the forum did not find it. Looking for advice on how BEST to brew? Can someone help with a material? I would be grateful for any useful advice.
Low loader trawls are widely used in modern cargo transportation, having a number of advantages over their standard counterparts. The main feature of the trailer lies in the low location of the platform, which makes it possible to transport goods under power transmission towers, bridges and other obstacles. Unfortunately, such a design feature also determines the most vulnerable spots, which is why the repair of low-loader trawls is periodically required. With the highest level of efficiency and at a low price, it will be carried out by the specialists of the "Trakservice Perm" company!
These trailers are quite complex structures, and therefore, when working with them, it is necessary to solve a set of tasks:
It should be noted that the repair process may involve not just the return of the functions lost by the trailer or the restoration of its working capacity. The specialists of our company are ready to take on the improvement of structures. So, welding of special stops is in high demand, making it possible to firmly fix flashing beacons that increase the visibility of the vehicle on the road, markings and other details.
Repair of low loader trawls is carried out in full compliance with the following rules:
