Abstract

The invention refers to an electromagnetic system that ensures the operation of trailers coupled to various types of vehicles, in any road conditions. The system is made up of a coupling axle (1) and a connecting axle for the braking cable (10), adjustment of these two being done by means of some clamping bushes (7), safety bushes (9), resistance bushes (8), a nut (4), a counter-nut (5) and a spring (6). The system is controlled by an electric circuit that supplies an electromagnetic coil (11) positioned between the safety bushes (9) and the connecting axle. The invention ensures safety and ease in operating vehicle trailers (10).

Description

Invenția se referă la un sistem electromagnetic ce asigură funcționarea în orice regim de mers a remorcilor cuplate la diverse autovehicule.The invention relates to an electromagnetic system that ensures the operation in any driving regime of trailers coupled to various vehicles.

Sunt cunoscute diverse mecanisme și sisteme mecanice de tractare a remorcilor, ele prezentând dezavantajul unei exploatări greoaie atât la mers normal, cât și la mersul înapoi, caz în care se solicită intervenția repetată a conducătorului auto.Various mechanisms and mechanical systems for towing trailers are known, presenting the disadvantage of cumbersome operation at both normal and reverse speeds, in which case the repeated intervention of the driver is required.

Sistemul electromagnetic, conform invenției, înlătură dezavantajele soluției cunoscute prin aceea că este format dintrun ax de cuplare filetat exterior, pe care se montează o bucșă cu filet interior, cele două piese fiind introduse în corpul dispozitivului, care reprezintă ansamblul, unde cu ajutorul unei piulițe și contrapiulițe se stabilește reglajul față de axul de legătură al cablului de frânare. Reglajul se realizează și cu ajutorul unui arc aflat între axul de cuplare și axul de legătură și a unor bucși de fixare, de rezistență și de asigurare remorcă, fixate împreună cu o bobină electromagnetică pe axul de legătură a cablului de frânare, realizând blocarea acestui ax și frânarea prin autoinerție.The electromagnetic system, according to the invention, removes the disadvantages of the solution known by the fact that it consists of an outer threaded coupling shaft, on which is mounted an inner threaded bush, the two parts being inserted into the body of the device, which represents the assembly, where by means of a nut and the nuts and bolts are set to the braking cable connection shaft. The adjustment is also made by means of a spring located between the coupling shaft and the connecting shaft and of the fastening, resistance and trailer bushings, fixed together with an electromagnetic coil on the connecting axis of the brake cable, blocking this axis. and braking by self-injection.

Sistemul electromagnetic, conform invenției, prezintîă următoarele avantaje:The electromagnetic system, according to the invention, has the following advantages:

- construcție robustă și asigură în exploatare;- robust construction and ensures in operation;

- asigură ușurință de exploatare a remorcilor;- ensures ease of operation of trailers;

- împiedică modificarea poziției remorcii fără acordul proprietarului.- prevents the trailer position from being changed without the owner's consent.

Se dă în continuare un exemplu de realizare a sistemului electromagnetic conform invenției, în legătură cu figura ce reprezintă schița sistemului.The following is an example of an embodiment of the electromagnetic system according to the invention, in connection with the figure representing the system sketch.

Aceasta cuprinde axul de cuplare 1, filetat exterior, ce se fixează la cârligul de remorcare al autovehiculului, pe care se montează o bucșă 2 (2 buc.) ce asigură prinderea dispozitivului pe remorcă, cele două bucși fiind introduse în corpul unui dispozitiv 3, axul 1, fiind prevăzut și cu o piuliță de reglaj 4 și o contrapiuliță 5, cu ajutorul cărora se face reglajul față de axul de legătură a cablului de frânare 10. Reglajul se face și prin intermediul unui arc 6, fixat pe axul de cuplare 1 și pe axul cablului de frânare 10 și totodată și prin intermediul unei bucși de fixare 7, a unei bucși de rezistență 8 și a unei bucși de asigurare 9, toate aceste bucși fiind montate pe axul de legătură 10, între bucșa de asigurare 9 și axul de legătură 10, fiind montată o bobină electromagnetică 11.This comprises the coupling shaft 1, outer thread, which is fixed to the towing hook of the vehicle, on which is mounted a bushing 2 (2 pcs.) Which ensures the attachment of the device to the trailer, the two bushes being inserted into the body of a device 3, the shaft 1, being also provided with an adjusting nut 4 and a lock nut 5, by means of which the adjustment is made with respect to the connecting axis of the brake cable 10. The adjustment is also made by means of a spring 6, fixed on the coupling shaft 1 and on the shaft of the brake cable 10 and also by means of a fastening bush 7, a resistance bush 8 and a bushing 9, all these bushes being mounted on the connecting shaft 10, between the bushing bushing 9 and the shaft connection 10, an electromagnetic coil 11 being mounted.

Funcționarea sistemului se realizează prin alimentarea bobinei electromagnetice 11, prin intermediul unui circuit electric, comandat din cabina autovehiculului printr-un contact electric, fiind cuplat la priza electrică pentru remorcă. Astfel se asigură blocarea și deblocarea frânei de la remorcă. Din momentul decuplării contactului, nu se mai asigură alimentarea bobinei 11, Blocarea statică asigurându-se prin intermediul bucși filetate de asigurare9, care se poate regia normal în funcție de necesități.The operation of the system is accomplished by supplying the electromagnetic coil 11, by means of an electric circuit, controlled from the cab of the vehicle by an electrical contact, being connected to the electrical socket for the trailer. This ensures that the brake on the trailer is locked and unlocked. Since the contact is switched off, the supply of the coil 11 is no longer ensured, the static locking being ensured by means of threaded bushings 9, which can be adjusted normally according to the needs.
