Definitions
- the invention relates to a jack bracket according to the preamble of claim 1 and a method for its production according to the preamble of claim 18.
- a generic console or a generic method is known from DE 195 28 309 C2.
- the console described there is formed from a sheet metal shell construction and has connection areas via which it is attached to a lower sill area by means of spot welding.
- the welded shell construction has an opening into which a plastic plug is fitted, which has an indentation into which a pin of a jack can be inserted.
- the shell construction of the console is relatively complex in terms of process engineering and apparatus because of its multipart nature.
- its construction is to be specially adapted in a complex manner to the introduction of force into the console when lifting the car, so that buckling of the construction due to overload is avoided.
- the invention has for its object a generic console and a generic To further develop methods in such a way that the manufacture and design of the console is simplified without sacrificing stability.
- the console By designing the console as a hollow profile, which is provided at one end with a cover having the opening for receiving a jack, the use of a complex shell construction can be omitted.
- the circumferentially closed hollow profile which can easily be created from a drawn tube, a rolled and then longitudinally welded sheet metal blank or an extruded profile, has a high level of bending and torsional rigidity, which means that the console is subject to high mechanical loads such as those encountered when lifting wagons can stand further.
- the hollow profile only has to be joined with the lid, for which a variety of joining techniques that can be carried out without great effort, such as resistance spot welding, laser welding, gluing, riveting or a combination of these processes, can be used.
- the hollow profile is formed by an internal high-pressure formed part.
- the hollow profile is formed from a tubular blank that is bulged by means of internal high-pressure forming.
- the hollow profile can be ideally adapted to the periphery of the console by means of the internal high pressure forming, these adaptations being expressed in bulges which can be represented in a simple manner in the internal high pressure forming process due to the relatively low degrees of deformation.
- the connecting flanges are formed from wall parts of the hollow profile. This means that there is no need for additional separate flange plates, which keeps the number of components low, and there is no need to attach them to the hollow profile, which saves unnecessary joining effort.
- the one-piece design of the flanges with the hollow profile improves the stability of the bracket against mechanical loads.
- a corresponding especially preferred further development of the method according to the invention represents claim 23 with regard to the design of the flanges.
- wall sections are notched or cut out in a simple manner at the end of the hollow profile remote from the cover. Due to the missing wall sections, the weight of the hollow profile is reduced, which is beneficial for the lightweight construction of the motor vehicle.
- Notching or trimming can be carried out in a process-economical manner after the hollow profile has been formed by means of internal high pressure with existing internal high pressure in the same internal high-pressure forming tool. Furthermore, at least a part of the wall parts forming the remaining flanges, which are spaced apart from one another by the resulting gap, is angled, which takes place outside the internal high-pressure forming tool.
- the connection of the hollow profile to the position of the connection surfaces of the sill area and other adjoining body areas is adapted as well as possible by means of a suitable angling, in order to be able to join the console with these areas quickly and durably.
- a connection method such as resistance spot welding, laser welding, soldering or clinching is advantageously used.
- large-area flanges can be designed in a "garden fence" manner, for example by notching. However, here the effort for the seam sealing to be applied to avoid crevice and edge corrosion is greater.
- the cover has a sleeve-like extension, by means of which the cover is plugged onto the hollow profile.
- the lid can easily be on the hollow profile be positioned without having to provide any holding device.
- the hollow profile is given a higher rigidity due to the overlap of the hollow profile and cover in the plug-in area.
- a sheet metal blank is used to produce the cover, which is deep-drawn to a cap-like cover with very little effort. The cover thus produced is preferably perforated in the center, in particular punched, which can be done in the deep-drawing tool while reducing the outlay on equipment.
- a progressive tool can be used to improve economic production.
- the cap-like perforated cover is placed on the hollow profile and then connected, preferably welded, to the hollow profile around the area of the end face of its cylindrical edge which forms the above-mentioned sleeve-like extension. Because of the plug-in connection, it is possible to connect the cover and the hollow profile in a particularly durable and non-detachable manner by means of a fillet weld which is very simple to carry out in terms of process engineering around the end face of the edge. In addition to fillet welding, there are conceivable alternative and easy-to-carry out joining techniques, for example in clinching and spot welding.
- the lid has a bottom area which is largely flat. This will make it easier to coordinate the installation of the holder on the cover possible, with the uniform system achieved achieving better force transmission into the console. Furthermore, the mounting of the receptacle is made easier, since the simple contact contour provides a well-defined stop for the receptacle.
- the cover is aligned parallel to the roadway over the entire floor area in the installed position of the jack console in the motor vehicle. This prevents cumbersome and unsafe positioning of the jack on the jack bracket.
- the content of claim 7 represents a further preferred development.
- the cover has beads in the base area, which give the cover and thus the console an improved rigidity.
- the cover has positioning holes in the base region for an assembly device.
- the cover is precisely fixed via these holes, after which it always assumes the correct relative position when assembled with the hollow profile.
- the fixation enables a defined feed of the assembled and joined console to the sill, so that the connecting flanges lie precisely against this and in the desired position. The consequence of this is that the connection between the console and the sill can be carried out reliably, which guarantees the durability of the connection during driving.
- Another advantage of the formation of the positioning holes is that the liquid in the cathodic dip painting process and the liquid entering the Driving operations such as water or oil can run out of the console, so that on the one hand the holder can be installed without hindrance and on the other hand the risk of corrosion of the console is minimized.
- the content of claim 9 relates to the different size of the positioning holes. This eliminates the risk of the console position being mixed up by the worker, since otherwise an identical rotational position of the cover of the console by 180 ° would also be possible with regard to the positioning holes.
- a further particularly preferred embodiment of the invention according to claim 10 shows that the central opening of the cover is delimited by a collar set towards the hollow profile.
- the collar increases the rigidity of the cover and thus the bracket on the one hand and on the other hand simplifies the connection of the receptacle to the cover, which can be pressed into the cover opening to form the connection, for example, by a central pin of the receptacle.
- the connection by means of clipping is particularly advantageous and secure.
- the central openings of the cover can also be used advantageously for the production process of the motor vehicle in the suspension or skid conveyance. This is because the openings consistently form receiving points of an identical position, which, because of the simplified referencing of the position of the vehicle, benefits the mostly tolerance-sensitive station production, such as, for example, axle assembly.
- the inclusion of one Plug formed which is preferably made of plastic.
- the stopper has at least one clip element on its side facing the cover, which interacts with the central opening of the cover.
- the circumferential outside of the stopper in the fastening position is flush with the cylindrical edge of the cover or is set back from it. This guarantees a safe introduction of force into the console, preventing the plug from kinking when subjected to impact, which would occur if the plug protrudes beyond the edge of the cover.
- the cover and the stopper as well as the connection cross section of the hollow profile to the cover can have any cross-sectional shape.
- the end of the stopper facing away from the cover is offset downward from surrounding damage-critical components of the motor vehicle.
- Vehicle such as the rear axle, exhaust system, aggregates, side members and cross members of the body due to excessive mechanical shock, for example when the vehicle sits on the curb in the course of the curb ascent and descent prevented.
- the console according to the invention thus serves not only for attaching a jack when changing a wheel, but also advantageously as impact or shock protection for the vehicle components mentioned.
- the contour of the connecting flange-forming wall parts of the hollow profile and the contour of the sill in the attachment area of the bracket are designed in a manner corresponding to one another, so that a secure connection of the bracket to the sill results in a simple manner ensures a durable connection.
- a further preferred development of the invention according to claim 16 consists in that the brackets on the sill in front of the rear wheel and behind the front wheel of the motor vehicle are designed identically. As a result, the manufacturing process is simplified due to the minimization of the outlay on equipment.
- the console is located outside the component separation between a rocker panel and an underbody panel of the motor vehicle, the console projecting through an opening in the underbody panel.
- At least two axially spaced, bulged sections are formed from the blank by the internal high pressure, which are then separated into separate hollow profiles by a separation process.
- several hollow profiles can be formed at the same time with a single shaping process by means of the subsequent separation process, which is carried out economically in the internal high-pressure forming tool, which mass production of the console with a short work cycle provides positive feed.
- Claim 21 represents a further particularly preferred embodiment of the method according to the invention.
- the blank is accordingly separated after the shaping between the bulged sections transversely to the longitudinal axis of the blank to form individual blank sections, which are then approximately in the middle by a further separation process which takes place transversely to the axial extension of the blank section two hollow sections are separated.
- the bulging of the sections of the blank is used to create absolutely identical double parts in a simple manner by means of a symmetrical separating cut, whereby on the one hand the forming tool is utilized to a particularly high degree and on the other hand the mass production is increased and the Work cycle for manufacturing the console can be accelerated.
- the separation process can take place within the internal high-pressure forming tool, but this limits the variety of possible uses for different processes. Mechanical separation methods such as punching or cutting using a rotating knife are practically practicable there. Likewise, it is conceivable to have the separation following the hydroforming process outside the forming tool. This enables further separation processes to be used. Laser cutting or plasma cutting are also possible.
- the non-bulged ends of the blank are cut off after the shaping.
- this end unnecessarily extends the hollow profile and its shape is not adapted to the installation environment. Furthermore, such an end means completely unnecessary additional weight. To avoid these drawbacks, the ends are cut off.
- the notching takes place during or after the internal high pressure forming of the hollow profile in the case of existing internal high pressure in the Internal high-pressure forming tool, which is particularly economical from the process of avoiding sink marks which undesirably change the shape of the flanges.
- FIGS. 1-4 in a perspective view continuously one stage at a time of the manufacturing progress of a console according to the invention
- FIG. 5 is a perspective view of a cover and a hollow profile before assembly to a console according to the invention
- FIG. 6 is a cross-sectional view of a jack bracket according to the invention in the installed position on a motor vehicle
- Fig. 7 is a perspective view of a bulged tubular blank with notches.
- FIG. 1 shows an elongated tubular blank 1 which has been bulged by means of internal high-pressure forming and has a plurality (here: four) of bulging sections 2 which are axially spaced apart.
- the blank 1 has non-bulged short sections 3 between the sections 2.
- the shaped blank 1 After the shaped blank 1 has been removed from the internal high-pressure forming tool, its undeformed, non-bulged ends 4 are cut off. At the same time or subsequently, the blank 1 is in place the short sections 3 separated transversely to the longitudinal axis 5 of the blank to form individual blank sections. These blank sections are then separated into two hollow profiles 6 approximately in the middle by a further separation process which takes place transversely to the axial extent of the blank section, of which a single one can be seen in FIG. 2. At the end 7 of the hollow profile 6, which is closed at the periphery, the wall sections are notched or cut out, leaving gaps 8.
- a part 9a of the remaining wall parts 9, which are spaced apart in the circumferential direction by the resulting gaps 8 and form the flanges of the bracket 12, are now angled to accommodate the adaptation to the connecting surfaces of the sill area and the surrounding body area, so that the bracket 12 can be joined in a simple manner to the connection surfaces with the sill and surrounding body parts.
- the bracket 12 At the end 10 of the hollow profile 6 near the cover, the latter has an almost circular peripheral region 11, onto which a cover to be joined can be attached (FIG. 3). The formation of the peripheral region 11 serves to facilitate the attachment of the cover.
- a cap-like cover 13 is plugged onto the peripheral region 11 of the hollow profile 6, which is deep-drawn from a sheet metal blank and perforated in the middle to form an opening 16 for the receptacle to which the jack can be attached, was especially punched.
- this was connected to the hollow profile 6, preferably welded.
- the cover 13 has a base region 17 which is largely flat. Furthermore, the cover 13 has beads 18 in the base region 17, which are arranged offset in the circumferential direction of the circular base region 17 in the manner of a five-pointed star by 72 ° in each case. In addition, positioning holes 19 for a mounting device are formed in the bottom region 17, which are of different sizes. Furthermore, the cover 13 has a collar 20 which is set toward the hollow profile 6 and which delimits the central opening 16 of the cover 13 formed in the base region 17.
- the circumferential region 11 of the hollow profile 6 is inserted into the cover 13, bearing against its edge 15, and connected to it, preferably welded, glued or enforced, but it is also conceivable that that cover 13 and hollow profile 6 are dimensioned such that the cover 13 is inserted with its edge 15 into the through opening 29 of the hollow profile 6 and then firmly connected to the peripheral region 11. 5, the wall parts 9 of the hollow profile 6, or the later jack console 12, which form the fastening flanges, can be seen particularly clearly.

- the cover 13 of the bracket 12 is aligned parallel to the roadway over the entire floor area 17.
- the console 12 am Sills 26 in front of the rear wheel and behind the front wheel of motor vehicle 30 have the same design.
- the contour of the connecting flange-forming wall parts 9 of the hollow profile 6 and the contour of the sill 26 in the attachment region of the bracket 12 are designed in a manner corresponding to one another, so that a gap-free contact with one another and thus a particularly durable connection result.
- the receptacle of the console 12 is formed by a stopper 21, which is preferably made of plastic and the circumferential outer side 24 of which is set back from the cylindrical edge 15 of the cover 13 in the fastening position.
- the stopper 21 of the stopper 21 lies on the underside 31 of the cover 13 without a gap.
- the plug 21 also has a central through bore 32, which is penetrated by a clip element 23.
- the clip element 23 is hollow and has at its end 33 remote from the cover an annular collar 34 with which the clip element 23 abuts a stepped shoulder 35 of the through hole 32.
- a plug 37 is pressed into the cavity 36 of the clip element 23, which secures the clip element 23 in the through-bore 32 of the plug 21 and, in contact with the annular collar 34, covers it from the outside.
- the plug 37 is additionally secured by a locking ring 38 in the through hole 32, which is embedded in a receiving groove 41 formed on the circumference 39 of the head 40 of the plug 37.
- the head 40 of the stopper 37 is flush with the end 25 of the stopper 21 facing away from the cover.
- the end face 25 of the stopper 21 facing away from the cover is offset downwards from surrounding damage-critical components of the motor vehicle 30.
- the clip element 23 is on his End 42 near the cover is designed in the form of a circumferential anchor hook which extends through the central opening 16 of the cover 13 and engages around the circumferential collar 20 there and thus fixes the stopper 21 to the cover 13.
- the plug 37 is hollow over the length of the hook, so that the hook is given sufficient elasticity to be able to retract radially inward when inserted into the cover opening 16 and to spring back behind the collar 20 into the securing position.
- the clip element 23 thus interacts with the central opening 16 of the cover 13.
- the plug 21 also has a hollow, central, short neck 43 which is inserted into the opening 16 and bears on the inside of the collar 20.
- the hook of the clip element 23 includes the neck 43 in the installed position with the collar 20. The positive and frictional connection of the stopper 21 to the cover 13 with the stopper 21 provides a particularly good hold on the cover 13.
- the console 12 is outside the component separation between a rocker panel 27 and one
- Underbody cladding 2 of the motor vehicle 30 is located and protrudes with the receptacle, i.e. the plug 21 has an opening 44 in the underbody panel 28.
- FIG. 7 shows a hollow profile blank 1 before the separation into the hollow profiles 6 forming the brackets 12, the blank 1 having sections 2 that are already bulged.
- notches 45 are produced by means of appropriate stamps, which form the gaps 8 after the separation (see FIG. 2).
- the separation takes place by separating cuts transversely to the longitudinal extent of the blank 1, which on the one hand run centrally in the bulged section 2 and on the other hand between the notches 45a and 45b which are axially separated from one another in pairs by a web 46.
- the mentioned web 46 is completely removed during the separating cut.
