Definitions
- the present invention relates to the field of tools useful for assembling and maintaining suspensions motor vehicles.
- Motor vehicle shocks include coil springs that need to be compressed to separate them from the damper organ properly said or to extract the damped suspension unit of a vehicle.
- compressors are known from springs provided for this purpose: All have a cylinder (mechanical, electrical, hydraulic or pneumatic) including at least two telescopically movable elements relative to each other with, linked to each element, a gripping member for cooperating with the spring (a turn portion of it for each organ) to compress it.
- a cylinder mechanical, electrical, hydraulic or pneumatic
- gripping member for cooperating with the spring (a turn portion of it for each organ) to compress it.
- the cups offer a spring support on a line of contact along which the burden is better distributed than in the case of claws where at best three point areas are in contact spring, with high concentrations in these areas constraints.
- the cups are geometry fixed and impose to have several sets of cups to treat the different dimensions of springs who meet on the market while claws, because of the articulation of the arms, can embrace with the same game a greater dimensional variety of springs.
- Cups like claws are often badly adapted to grip the turns of suspension springs which are close to the plates of their end support.
- the present invention is intended to combine the benefits of claws and cups while removing most disadvantages, with the added advantage to have to use only a set of jaws for work on the vast majority of suspension springs present on the market.
- the invention therefore relates to a compressor of springs comprising a jack with a body and a telescopically movable rod one with respect to the other and two jaws each comprising a part attachment to the cylinder and a work piece intended for to come into engagement with a coil of a helical spring.
- the working part of each jaw has first and second pieces, the first piece being connected to the attachment part and defining a section of track for the support of a portion of a spring turn, provided along its inner edge of a retaining rim of the spire and the second piece being in the form of an arm, articulated either to the first piece is at the attachment part swim from one end of the runway section around an axis substantially perpendicular to the surface of the runway and forming at its free end a zone of support a spring turn that can be cradle-shaped or gutter or that may include a hook or rim of radial retention of the coil of the spring.
- the jaw thus formed presents a bulk very inferior to known cups while offering an important contact with the coil of the spring in taken at the level of the track section.
- this jaw is more resistant than a jawbone that has two joints through which almost all the effort of compression, joints that are the places mechanically the most fragile of a claw jaw.
- the upper surface of the track may be substantially circular ring sector shape flat and inclined relative to the axis of the attachment part an angle that corresponds substantially to the angle propeller that makes each coil of spring. She can also be helically shaped. It can furthermore be orientable around an axis perpendicular to the axis of the attachment part to take into account the variation the pitch of the spring's propeller during its compression or decompression.
- the claw arm is articulated around an axis (substantially perpendicular to the runway) whose orientation in space and in relation to the surface track section will be determined in such a way that the cradle or end gutter of that arm is roughly speaking in the circular extension of the track surface so that the support points belong substantially to a congruent surface with that of the spring portion in contact with which they are when the jaw is in engagement.
- the shape of the arm itself will be studied to give it the most maneuverability possible.
- a bisecting plane of the spring turn portion embraced by the working part of the jaw is located on the side of the arm relative to a plane passing through the center or axis of the spring and the center or axis of the attachment part from the jaw to the jack.
- the jaw 1 represented in FIG. attachment part 2 to a compressor cylinder of spring and a work part 3 connected to the part attachment 2 and intended to be engaged with a turn of the spring to compress.
- Work part 3 is in two pieces.
- a first piece 4, here in one piece with the attachment part 2 defines a section Track 5 circular, planar or helical. At one of its ends 5a, the narrowest, the track 5 is overhung by a leg 6 which forms a hook under which a spring coil can be slid.
- This tab 6 is from the inner edge 5b of track 5 which has a flange or bib 7 retaining the coil of the spring.
- This flap 7 extends to the figure all along the internal edge 5b of the track.
- this bib can occupy only the central part of this inner edge.
- the section of track is dug (reference 5d) or beveled so that the thickness of the wall of the room 4 which forms the track at this point is gradually diminished.
- This bevel allows to accommodate the end 5a from the end of the runway to the furthest point in the angle formed by a coil of spring leaving its end plate.
- the other end 5c of the runway section 5 is wider that the end 5a (in its dimension taken radially), which allows it to be able to accommodate such springs only 8, 9 of different winding diameter.
- the piece 4 bearing the runway section 5 has an articulation clevis 10 with an axis 11 on the outside of the runway, for a arm 12 which forms the second piece of the work part of the jaw and whose free end includes two edges 13 and 14 which define with the arm a cradle or gutter taking over the spire spring 8 or 9.
- the cradle 13, 14 of this arm can be replaced by an end possessing, as the end 5a of the section of runway, a leg overhanging a surface of taking charge of a spring coil.
- the end of the arm 12 can, also like the stretch of track, be of a diminished thickness gradually.
- the axis 11 is oriented so as to be substantially perpendicular on the surface of runway section 5 so that the end cradle of the arm 12 is substantially in the extension of the upper surface of the section runway 5.
- FIG. 3 is a sectional view along the line III-III of Figure 1 of the articulation of the arm 12 to the piece 4. We find in this figure the elements described previously with the same references.
- the end 5a of the track section and the end of the arm 12 is very largely circumferentially displaced by compared to a plan such as P3 that would go through the center spring and the center of the attachment part.
- the jaw according to the invention has all the advantages of the jaw deported being the subject of the French patent FR 2,674,167 in the name of the applicant.
- Figure 2 illustrates by a diagram on which represented in dotted line in addition to the jaw 1, a jaw 1 'in its working position when is hitched to the spring compression cylinder, for example to the rod of this cylinder while the jaw 1 is hitched to the body of it.
- the jaw 1 ' is, in the case of the figure, identical to the jaw 1 but returned so that both active surfaces of the jaws 1 and 1 'face each other.
- the spring 9 is caught between these two jaws so very enveloping, the angle A in the center of the spring 9, corresponding to the extent of the angular arches of the spring kissed by each jaw, being superior to 180 °.
- the spring thus compressed no longer tends to bend during compression.
- the invention offers increased ease of implementation of the compressor on the spring, thanks to the arm that at the time of assembly, one can first move away from the spring around its articulation then bring it closer after having correctly put in place - particularly towards the support base - one of the sections of track.
- an attachment part 2 of the jaw which is in the general form of a sleeve 20 whose central recess 21 is U-shaped open laterally on the opposite side to the work area 3 of the jaw.
- the sleeve 20 has at its end turned on the side of the back side of the working part, a countersink 22 whose inside diameter, greater to the width of the central recess 21, centered on the half-cylindrical part of the U-shaped recess 21 corresponds to the outer diameter of a body collar 101 100 of a compression cylinder (see Figure 8) while the width of the U-shaped opening 21 corresponds to the diameter of part 102 of this body 100 immediately adjacent at this collar 101.
- Exhibit 4 of the working part of the jaw according to the invention is not in one piece with the attachment part 2. Indeed the connection between part 4 and the part attachment 2 is effected by a T-slot 23 of this part of attachment that receives with play a head of link 24 complementary complementary form of the piece 4. Attachment part 2 and part 4 are furthermore connected to each other by an axis 25 which makes it possible to render indissociable these two elements while leaving a possibility to the room 4 to oscillate with respect to the part attachment 2 with a deflection that will function of the game left between the groove 23 and the head 24. The part of work 3 is then said to be pallet with respect to the Attachment part 2 of the jaw. This possibility swiveling or tilting of the working part allows to the jaw to take into account the variation of the angle spring propeller during compression.
- the attachment part 2 of the jaw who has a T-head 26 while piece 4 of the working part of the jaw part defining the track section 5, has an opening 27 capable to welcome with play the head 26.
- the lifting of this part 4 with respect to part 2 is performed as described in French patent FR 2,653,051, by the possible pivoting of the piece 4 on the foot 26a of the head 26 thanks to the lateral opening 27a in shape U of the opening 27.
- the arm 12 of the working part is articulated in a clevis 28 that is carried by the attachment part 2 of the jaw.
- the lifting is, in this variant embodiment, limited to piece that carries the section of track, which allows to improve the contact between this track and the coil of the spring.
- FIG. 6 there is shown a leg of force of a motor vehicle suspension which comprises known, a damper body provided with a plate 31, a damper rod 32, partially shown for the clarity of the drawing and which also carries a plate 33 and a spring 34 compressed between the two Plates 31 and 33.
- a damper body provided with a plate 31, a damper rod 32, partially shown for the clarity of the drawing and which also carries a plate 33 and a spring 34 compressed between the two Plates 31 and 33.
- two jaws 1 and 1 'of a compressor spring coupled to a cylinder 35.
- the area where the spring 34 leaves its support on the plate 31 is noted 36.
- the spring 34 leaves the plate 33 in the zone 37.
- the turn portions of spring 34 embraced by the jaws 1 and 1 'are respectively denoted 38 and 39 and their drawing is woven.
- Jaw 1 has been shown in its position where the end 5a is housed as close to the zone 36. It is found that the same end 5a of the jaw 1 ' is far from zone 37 which may be a slight inconvenience when compressing the spring but which has the advantage of leaving the compressor 35 a great angular latitude of setting up around the spring 34. This advantage is significant when it comes to under the vehicle that is to say in a space very cluttered around the plate 33 where often alone a small angular window is available to accept the cylinder.
- Figure 7 illustrates the use of a jaw 1 " at the level of plate 33 which is not identical to the jaw 1 but which is symmetrical with respect to a plane passing through the axis of his attachment part and by the axis of the springs to grasp (the plane P3 of Figure 1).
- This jaw 1 "allows to seize the spring closer of the zone 37 that the jaw 1 '(by the free end of his arm 12) but the wrapping of the spring by the compressor is less important.
- FIG 8 there is shown a cylinder body 100 having two collars 101 defining two possible positions of a jaw according to the invention along this body.
- Part 102 which overcomes each of the collars 101 has a threaded portion 103 which cooperates with a nut 104a, 104b for clamping the attachment portion of the cup against the corresponding flange 101.
- the realization of this cylinder body 100 is to achieve the threaded sections 103 before or after reporting the flange 101 farthest from the rod 110 by any suitable fastening means (welding, brazing, hooping ).
- the nut 104b is then reported on the thread 103 closest to this collar by having it previously split to make him pass the 102 zone no Threaded closest to the rod 110.
- the closure is carried out of its slot by a weld 105. We then put in place like the previous the second collar 101 and it is reported then the nut 104a.
