Abstract

The invention concerns a towing device (1) for a vehicle, especially private vehicles, which involves a weight-bearing tow-bar (3) with a towing ball (2), and a cross-bar divided into two parts (4, 5) with a square cross-section, whereby each cross-bar section (4, 5), at its own end, retains a traction device (6, 7) for connection to the vehicle. The two parts of the cross-bar (4, 5) adjoining each other are joined to the tow-bar (3) via a removable clamping device (10), which has two clamp units (11, 12). One clamp unit (11) is rigidly connected to the tow-bar (3), and is designed so that it connects with the underside of the cross-bar parts (4, 5) and with the sides of the cross-bar parts (4, 5) facing towards the towing ball (2). The other clamp unit (12) is adjustable and joined to the clamp unit (11) via a connector (17, 18) on the exterior of the cross-bar parts (4, 5), and it is so designed that it lies against the cross-bars' parts (4, 5) square cross-section which is unaffected by the permanent clamp unit (11)<IMAGE>

Description

15 20 p- 8203710-2 2 för fästorgan, vilka exempelvis_utgöres av skruvar 17 och mutt- rar 18. Tvärbalksdelarna 4,5 uppvisar var sin styrklack 19 respektive 20. Styrklackarna 19,20 säkerställer att klämdelen 11 blir riktigt monterad relativt tvärbalksdelarna 4,5. For fasteners, which for example consist of screws 17 and nuts 18. The crossbeam parts 4,5 each have their own guide lug 19 and 20, respectively. The guide lugs 19,20 ensure that the clamping part 11 is correctly mounted relative to the crossbeam parts 4,5 .

Det är vidare lämpligt att tillverka klämdelarna 11,12 så att de uppvisar en vinkel G som är något mindre än mot- svarande vinkel hos tvärbalksdelarnas 4,5 fyrkantiga tvärsnitt.It is furthermore suitable to manufacture the clamping parts 11,12 so that they have an angle G which is slightly smaller than the corresponding angle of the square cross-section of the cross-beam parts 4,5.

Därigenom säkerställes i monterat tillstånd en fullgod anligg- ning mellan klämdelarna 11,12 och tvärbalksdelarna 4,5.In this way, in the assembled condition, a satisfactory abutment is ensured between the clamping parts 11,12 and the cross-beam parts 4,5.

Montering av en draganordning enligt uppfinningen på ett fordon tillgår lämpligen så att.de två tvärbalksdelarna 4,5 först fastskruvas vid fordonet utan att tvärbalksdelarnas fäst- skruvar helt åtdrages, varefter dragbalken 3 anbringas vid tvärbalksdelarna 4,5 utan att klämanordningens 10 fästorgan 17,18 helt åtdrages. Därefter sker slutlig åtdragning av tvär- balksdelarnas fästskruvar och klämanordningens fästorgan i nämnd ordning. Härigenom uppnås även den fördelen att de drag- kraftupptagande anordningarna 6,7 erhåller en bättre anliggning mot hos fordonet belägna motsvarande anliggningsytor än vad som skulle vara fallet om tvärbalken bestod av endast en del.Mounting of a towing device according to the invention on a vehicle is suitably done so that the two crossbeam parts 4,5 are first screwed to the vehicle without the crossbeam parts' fixing screws being fully tightened, after which the towing beam 3 is applied to the crossbeams 4,5 without the clamping device 10, 18 fully tightened. Thereafter, the tightening screws of the cross-beam parts and the fastening members of the clamping device are finally tightened in the order mentioned. This also achieves the advantage that the traction-receiving devices 6,7 obtain a better abutment against the corresponding abutment surfaces located in the vehicle than would be the case if the crossbeam consisted of only a part.
