Description

The invention relates to a further improvement in the patent 818731 protected towline for motor vehicles. The application of the towline for trucks by reinforcement and the use of steel wire ropes certain modifications made possible by the invention described below.

The trucks consistently have facilities for towing and being towed, so this must be taken into account. Since towing lines made of fiber take on unwieldy dimensions, steel wire ropes have so far been used almost exclusively. This has Eigensichaften who have a number of disadvantages for the towing. The rod wire rope rusts easily; it is too stiff and therefore unwieldy and bulky; it tends to kink and thus creates places of particular weakness for the break; Individual wires break easily around the circumference, injuring the hands of the operators; in the event of any tearing, the flapping ends pose a threat to people standing nearby. In winter the steel wire rope is icy cold and thus hinders the. Attachment and removal. All of these disadvantages are eliminated by the invention. .

Instead of the steel wire rope, h-anfum-spun wire strands, which are stranded together, are used. Such tagu work is known and is used in sea fishing. The following:. The properties of the cordage make this in-connection =, g with the spring-loaded coupling, particularly suitable for a truck tow line. Its elasticity is several times greater than that of steel wire lines; it has no tendency to kink formation; rusting is excluded; there is no tearing of individual wires, endangering the operation; - The operation is as pleasant as with fiber rope. If the line tears completely, there is diminished; Danger for people in the vicinity . The lack of bulkiness allows it to be easily stowed on or in the vehicle.

In the drawing, the invention is shown b, eisp.i, # elweise.

Fig. I shows the, attachment of tow rope i and fastening strap 3; Fig. 7. shows the modification: on the safety coupling 2.

In order to absorb the large intermittent loads occurring in trucks and to keep the spring in the coupling as short as possible, a second spring 21 is arranged according to the invention above the existing spring 7 and, in addition, one of the two springs is kept shorter to ensure soft tightening . In order to achieve better control of the towed wagon, the fastening strap is kept for 3 sio long so that it can be attached to two hooks i # q and 20 or digl. can be placed on the towed vehicle, pulling it like an elastic double drawbar.

The eye 4 of the tow rope i is pushed through the Schleppbelzens 18 am, tugboat arrested.

Fig. I shows that the design of the towline ensures easy attachment and removal. -

Claims (1)

PATENT CLAIM: i. Tow rope for motor vehicles according to patent 818734, especially for trucks, characterized in that the strands attached to the safety coupling (2), namely tow rope (i) and attachment strap (3), consist of hemp-spun steel wire strands which are twisted together to form a rope 2 S.dfleppleinie - are ' according to claim 1, characterized in that a second compression spring (2 1) is arranged in the safety coupling (2) above the one compression spring (7). 3. tow line according to claim 2, characterized in that one of the two springs (7 or 21) is kept shorter to achieve a soft suit. 4. tow line according to claim i, characterized in that in order to achieve good control of the towed car of the Bef-e'stiguD9sstrOPP (3) . two points (19, 20) is placed outside the center of the towed vehicle and thus forms an elastic -double drawbar.
