Definitions

  • the invention relates to a straightening bench for the frame and the body of a vehicle.
  • the invention also relates to fastening means for fixing the vehicle to a straightening bench.
  • the document is also known WO2009 / 095533 describing a straightening bench also comprising a lifting spider but also plans for accommodating the wheels of the vehicle once it raised.
  • the vehicle can therefore rest on its wheels once raised and work other than straightening the chassis and bodywork may be performed on the vehicle.
  • the presence of the lift brace under the straightening table limits the possibilities of working on the vehicle and generates a footprint that prevents the use of certain devices such as ultrasonic chassis meters that requires the presence of a ruler under the vehicle.
  • An object of the invention is to provide a straightening bench for performing both the straightening operations in themselves and also to measure the effect of said straightening operations on the vehicle chassis without having to move the vehicle.
  • Another object of the invention is to provide an apparatus for carrying out any type of work on a vehicle: straightening of the vehicle, mechanical work, adjustment of the headlights, measurement of the chassis and geometry of the vehicle.
  • the straightening bench according to the invention can therefore be used as a conventional four-post lift once the wheels of the vehicle placed on the longitudinal beams. This makes it possible to carry out any type of mechanical work, since the mechanic has an optimal working space under the vehicle, once the latter is raised thanks to the lifting columns of the apparatus.
  • the work space underneath the vehicle allows to set up an ultrasonic chassis measuring device.
  • straightening and measuring work on the vehicle chassis can be carried out concomitantly without having to move the vehicle to another device.
  • the straightening bench according to the invention makes it possible to perform multiple tasks in one and the same place, without changing the vehicle's position.
  • the straightening bench according to the invention comprises means for varying the distance between the longitudinal beams.
  • Such means advantageously comprise rails on the transverse beams on which the longitudinal beams can slide.
  • This embodiment advantageously makes it possible to adapt the spacing between the longitudinal beams to the dimensions of the vehicle to be repaired.
  • vehicles of variable width can be repaired on the same straightening bench.
  • said straightening bracket is attached to said beam by means of removable fastening means.
  • the straightening bracket can indeed be moved to different places on the straightening bench beams, which will move it depending on the areas of the chassis or the body to straighten.
  • the beams of the straightening bench according to the invention are I-beams, the central part of said beams having a width sufficient to allow the rolling of a tire of said vehicle and the side parts being pierced with holes. at regular intervals.
  • the holes constitute practical fastening means for the straightening brackets and for any other tools or instruments to be used in combination with the straightening bench.
  • the removable fastening means of the straightening bracket comprise rods inserted into the holes of one of said I-beams.
  • rails are fixed on said I-beams, the straightening brackets being able to slide on said rails.
  • the straightening brackets can be moved along the beams of the straightening bench and therefore be positioned optimally according to the specificity of the straightening work to be performed.
  • the straightening bench according to the invention comprises a hydraulic jack fixed on one of said four beams, said jack being able to exert a vertical force on a vehicle point included in the perimeter defined by said four beams.
  • the straightening bench according to the invention comprises a rule for the calibration of an ultrasonic vehicle chassis measurement system fixed between said longitudinal beams by means of transverse beams connecting the longitudinal beams two by two. .
  • This embodiment therefore combines the straightening and measuring functions of the chassis in a single device, which offers optimal working conditions because the vehicle must not be moved to another device to evaluate the effect of the straightening work. This results in ease of use and considerable time savings for the bodybuilder.
  • the straightening bench according to the invention comprises a system for measuring the geometry of the wheels of the integrated vehicle on said longitudinal beams of the straightening bench.
  • a system can be directly integrated into the straightening bench according to the invention because the vehicle is placed on its wheels on the longitudinal beams.
  • the innovative approach of the straightening bench according to the invention which consists in keeping the vehicle on its wheels under all circumstances thus offers the possibility of carrying out any type of mechanical work on the vehicle without having to move the latter on other apparatus.
  • the straightening bench according to the invention is therefore in reality a multitasking apparatus whose design allows to gather in a single structure a set of tools and instruments that could not be used concomitantly in the prior art.
  • Another object of the invention is to provide means for attaching a vehicle to a straightening bench adapted to any type of body and vehicle chassis and is also easily and quickly implemented while offering important reliability.
  • the fastener for fixing a vehicle to a straightening bench comprises a rod, a groove being machined at one end of said rod, said groove dividing the end of said rod in two legs, each of the two legs including a through-hole, said two through-holes facing each other, and also includes a first jaw, said first jaw being inserted into said groove, said first jaw including a through hole facing the through-holes of legs of said rod, and a second C-jaw including a concave portion, a leg of said rod being inserted into the concave portion of the second jaw, said jaws including a plurality of through holes facing each other in pairs, bolts being inserted into said through holes to secure the first jaw to said rod and to secure the second jaw to the first m jaw.
  • cars having a tapered profile, and therefore non-parallel right and left spar reinforcements can be fixed without difficulty to a straightening bench using the fastening means according to the invention.
  • the possibility of varying the orientation of the jaws relative to the axis defined by the through holes drilled in the two legs of the rod makes it possible to maintain the attachment of the vehicle to the straightening bench even when the chassis of the vehicle is raised in one place.
  • said first and second jaws with their through holes facing each other can be brought closer to each other while remaining parallel thanks to screwing bolts and of nuts, which maximizes the area of the clamping zone and the clamping force between the two jaws and therefore the reliability of the fastener according to the invention. This effect is not observed for the fasteners of the prior art whose clamping zone results from a rotation and not from a translation of the first and second jaws.
  • the rod of the fastener according to the invention is threaded. Such threading will indeed allow easy attachment thereof to a beam of a straightening bench.
  • such fasteners are fixed to the longitudinal beams I of the straightening bench according to the invention by means of U-shaped pieces comprising a hole
  • fasteners can, however, be used directly only if the vehicle has appropriate reinforcements spar, that is to say, able to be firmly gripped by the jaws of the fastener. In the absence of such reinforcements of spars, said fasteners can not be used effectively.
  • Another object of the invention is to provide means to fix any type of vehicle to the straightening bench.
  • the chassis of a vehicle is in fact generally provided with holes drilled in its longitudinal members, generally protected by caches, intended to accommodate a jack when changing a wheel. Surprisingly, it has been found that these holes could be diverted from their primary function and used to attach the vehicle to the straightening bench. These holes are pierced in a very solid part of the chassis of the vehicle and therefore constitute an appropriate place to insert rods with anchor heads.
  • the anchor heads of the threaded rods must be designed so that they can be inserted into the jackhole holes while remaining anchored within them when positioned within them .
  • the anchoring head and therefore the rod must therefore be adapted to the particular model of the vehicle to be fixed to the straightening bench.
  • the beam advantageously comprises means for varying the distance between said two through holes, which allows it to be used for different vehicle models which therefore have a different spacing between their jack support holes.
  • the at least two rods of the anchoring kit are threaded and the fixing means of said rods to the beam comprise nuts.
  • the beam of the anchoring kit can be fixed to the vehicle by introducing the threaded rods into the through holes of the beam and fixing them with nuts.
  • the anchor rods are drilled with holes and pins are used to secure said rods to said beam once the anchor heads are introduced into the jack support holes.
  • the latter can be directly attached to the straightening bench using the previously exposed fasteners.
  • the invention therefore also relates to the use of vehicle jack support holes as means for fixing said vehicle to a straightening bench.
  • the Fig. 1 and Fig. 2 represent an embodiment of the straightening bench according to the invention.
  • the straightening bench comprises four lifting columns 1, two transverse beams 2b connected to the lifting columns 1, as well as two longitudinal beams 2a connected to the transverse beams 2b and intended to receive the wheels of the vehicle to be repaired.
  • Fastening means 4 of the vehicle longitudinal beams 2a of the straightening bench are present to immobilize the vehicle for straightening work.
  • the straightening brackets include hydraulic cylinders to move in three dimensions of the space and thus allow the straightening of the frame or the body once provided with chains or cables.
  • the longitudinal beams 2a and 2b of the transverse straightening bench are I-beams.
  • the width of the central portion of the longitudinal beams 2a is sufficient to accommodate the tire of the vehicle to be repaired.
  • the lateral parts of I-beams are provided with through holes drilled at regular intervals. Such holes are used for fastening U-shaped pieces 40 to which the fasteners 4 are fastened, and also for fixing rails 5 on which the straightening brackets 3 slide.
  • the lifting columns 1 of the straightening bench are provided with worm.
  • the longitudinal beams 2a can slide along the transverse beams 2b, so as to adapt the spacing between the longitudinal beams 2a to the specific width of the vehicle to be repaired.
  • the Fig. 3 shows in detail an embodiment of the fastener used to secure the vehicle to the straightening bench.
  • the fastener comprises a rod 10 having a groove 11 machined at one of its ends.
  • the groove 11 divides the end of the rod 10 into two legs 12a and 12b, each of the two legs comprising a through hole 13a and 13b, the two through holes 13a and 13b facing each other.
  • the clip also includes a first jaw 14, said first jaw 14 being inserted into the groove 11 of the rod 10.
  • This first jaw is provided with a through-hole 15 which faces the through-hole holes 13a and 13b of the legs 12a and 12b of said rod 10.
  • the through holes 13a and 13b of the rod 10 and the hole 15 of the first jaw make it possible to fix the first jaw to the rod 10 by means of, for example, a nut and a bolt at adapted dimensions (not shown).
  • the fastener also comprises a second jaw 16 of C comprising a concave portion 17, a leg of said rod 12a being inserted in the concave portion 17 of the second jaw 16.
  • the jaws 14 and 16 further comprise a plurality of through holes 18 and 19 facing each other in pairs. These through holes 18 and 19 make it possible to fix the first jaw 14 to the second jaw 16 using, for example, nuts and bolts of appropriate dimensions (not shown).
  • the rod 10 is advantageously threaded (not shown). In this way it can be easily attached to an I-beam of the straightening bench according to the invention.
  • the U-shaped piece 40 shown in FIG. Fig. 4 can be easily attached to the I-beams of the straightening bench according to the invention with its side portions 41 provided with through holes 42.
  • the central portion 43 is in turn pierced by a slot, it can accommodate the rod 10 which there is fixed by a nut.
  • the Fig. 5 represents for its part the beam 50 of the anchoring kit according to the invention intended to cooperate with the anchor rods 60 and 70 shown in FIGS. Fig. 6 and 7 .
  • This beam thus has two holes 51 and 52 adapted to receive the anchor rods 60 and 70 after they have been introduced into the jack support holes of a vehicle.
  • the spacing D between the holes 51 and 52 must therefore correspond to the distance between the jack support holes of the vehicle. Since this distance varies from one vehicle model to another, the beam 50 of the anchoring kit according to the invention advantageously comprises means for varying the distance between the through holes 51 and 52.
  • the beam 50 consists of two beams 53 and 54 secured to each other by means of fasteners 55 and 56, for adjusting the length of the beam 50 by varying the portion of the beams 53 and 54 overlapping.
  • Other means could, however, be used to make the same beam 50 adaptable to different vehicle models, such as for example a beam 50 in one piece pierced with through holes at different intervals corresponding to the standard dimensions of the vehicles to be fixed to the test bench. straightening.
  • the Fig. 6 and Fig. 7 therefore represent two embodiments of the rods 60 and 70 used in the chassis anchoring kit of a vehicle according to the invention.
  • the rods 60 and 70 have different anchor heads 61 and 71 which correspond to different embodiments for different vehicle models. Indeed, all vehicle models do not have identical jack support holes and it is therefore necessary to produce rods with suitable anchor head.
