ABSTRACT:

The present invention relates to the field of assembly and adjustment, particularly in the field of mounting components on motor vehicles.
More specifically, the invention relates in particular to an assembly device of the type comprising: an attachment bar having, over a given length, a partially circular cross section including at least one flat and having a minimum dimension and a maximum dimension; and a clamping collar comprising two lugs which can be brought closer together by tightening a screw which passes through them, the lugs before the screw is tightened being spaced apart by a distance greater than the minimum dimension and less than the maximum dimension, it thus being possible for the clamping collar to be mounted on the bar before the screw is inserted, by a transverse movement with respect to this bar.
BACKGROUND OF THE INVENTION
Devices of this type are well known in the prior art in various fields and are used in particular to allow the springs of brake-pressure equalizing devices to be attached to the vehicle.
One problem encountered, in this application in particular, lies in the fact that the assembly devices currently used offer no possibility of rotating the clamping collar about the bar and therefore no means of adjusting the length of the spring and in consequence no means of adjusting the tension of the latter either.
SUMMARY OF THE INVENTION
The invention falls within this context and its object is to propose a simple solution to this problem.
To this end, the assembly device of the invention, which in other respects is in accordance with the definition given in the above preamble, is essentially characterized in that the clamping collar comprises an open and deformable ring which is extended to form the two clamping lugs, this ring offering a substantially circular internal housing of diameter greater than the maximum dimension, and in that the device further comprises a profiled insert piece which has an internal profile shaped to at least partially mate with the cross section of the bar and an external profile shaped to at least partially mate with the internal housing of the ring, it thus being possible for this profiled piece to be inserted between the bar and the ring by a longitudinal movement with respect to the bar.
The bar may have two flats, in which case the profiled piece has a U-shaped cross section.
In all cases, the external profile of the profiled piece is preferably at least partially ridged.
The invention also relates to a method for attaching to a vehicle a spring of a brake-pressure equalizing device, this method employing a device as previously defined and essentially characterized in that it comprises the operations that consist in fitting the clamping collar around an anti-roll bar of the vehicle, this bar being used to act as an attachment bar; attaching the spring to one lug of the clamping collar; rotating the clamping collar about the bar until a final rotated position of the collar is obtained in which the spring is stretched to a predetermined length; and tightening the clamping collar in its final rotated position, using the screw.
