Description

METHODS FOR MANUFACTURING A CHASSIS COMPONENT}

The present invention

A joint receptacle is formed in the structural part,

A joint cartridge is inserted into the joint receptacle,

The structural part is fixedly coupled with the joint cartridge,

The joint cartridge is assembled into a joint,

One or several other joints are fixedly coupled with the structural part,

A method for manufacturing a chassis component.

Chassis components generally include structural components and one or more joints associated with the structural components. For example, such chassis parts form two-point links, three-point links or flange joints, which joints are generally integrated into the structural parts by press-fitting, screwing or nivetting. It is also possible to integrate the joint into an integral structural component housing. Such chassis parts have the following disadvantages in particular: large assembly space requirements, large fluctuations in joint property values, large weights, large numbers of individual parts, corrosive areas (eg, rolling edges of joints), large inventory of semi-finished products and large logistic cost.

In DE 603 04 709 T2 a wheel suspension arm for an automobile is known which comprises a body formed of stamped sheet metal, which is connected to the wheel carrier by a ball joint and to the vehicle body by two bearings. The ball joint includes a lower holder and a cover. The lower holder is inserted into the housing formed into the body and lies on the side edge of the housing by side projections. The cover is placed on the lower holder and joined to the surface of the body by laser welding.

In the wheel suspension arm, tolerances can be added undesirably while the lower holder and cover are assembled to the body. In addition, after the body, the lower holder and optionally the cover have been cleaned after assembly, a protective coating must be provided on the parts. Providing different coatings to the body, the lower holder and optionally the cover is costly.

On the basis of this prior art, the object of the present invention is to enable the integration of joints in structural parts with a high degree of accuracy in the chassis parts of the aforementioned manner.

The problem is solved by the method according to claim 1 according to the invention. Preferred embodiments of the invention are set forth in the dependent claims.

The manufacturing method of the chassis component according to the present invention

Forming a joint receptacle in the structural part,

Inserting a joint cartridge into the joint receptacle,

Fixedly coupling said structural component with said joint cartridge,

Assembling the joint cartridge into a joint,

Prior to forming the joint receptacle in the structural part, securely coupling one or a plurality of other joints with the structural part.

The joint receptacle is formed only after one or a number of other joints are fixedly coupled with the structural part, so that the position of each other joint is known. As such, information about the position of the other joint (s) can be used to form the joint receptacle. In particular, the point at which the joint receptacle is formed in the structural part is determined in accordance with the position (s) of the other joint (s) in fixed engagement with the structural part. Due to this, high accuracy of the joint position can be obtained. In particular, high accuracy can be achieved in comparison with conventional chassis parts in which the joint receptacle is already formed before the joining of the structural part with one or a number of other joints, since the assembly of each of the other joints involves positional inaccuracy. to be. Thus, a clear improvement over the prior art is possible from a kinematic point of view.

Said positions or each of said positions is preferably indicated or formed by the kinematic points of each other joint. Thus, the point at which the joint receptacle is formed in the structural part is determined in accordance with the kinematic point (s) of the other joint (s) in fixed engagement with the structural part.

The other joint (s) form or include a rubber or elastomer bearing, ball joint or ball and socket joint. Preferably the other joint (s) comprise or form one or more rubber bearings.

The structural part is permanently fixedly coupled to the joint cartridge by means of a materially bonded joint method. The material-bonded joint method may be referred to as a heat-coupled material-bonded joint method, for example because it includes or includes a thermally-coupled joint method. Preferably the material bonded joint method comprises beam welding, in particular laser beam welding. Due to this, the joining of the structural part and the joint cartridge can be achieved with very low tolerances.

The structural part is permanently fixedly coupled to the joint cartridge by means of a materially bonded joint, which is formed in particular by a materially bonded joint method. Material bonded bonding includes, for example, one or multiple welding seams.

The joint cartridge is assembled into the joint, in particular by the joint internal parts being inserted into the joint cartridge and movably supported within the joint cartridge. Preferably the joint internal part extends from the joint cartridge. In particular, the joint internal part extends from the joint cartridge through the joint cartridge opening.

Preferably the joint cartridge is preassembled into a joint. For this purpose, in particular, after the joint internal part is inserted into the joint cartridge and is movably supported in the joint cartridge, the joint cartridge may be inserted into the receiving part or combined with the structural part, and at the same time the joint cartridge is inserted into the receiving part Sometimes combined with Thus, the joints are manufactured with high accuracy regardless of the structural parts.

Preferably the joint cartridge is coated, in particular precoated. To this end, a coating may be provided to the joint cartridge, in particular before the joint cartridge is inserted into the receptacle or before the structural part is joined with the joint cartridge, and at the same time before the joint cartridge is inserted into the receptacle, the structural part is jointed. The coating is provided before being combined with the cartridge. Preferably the structural parts are coated, in particular precoated. To this end, a coating is provided on the structural article, in particular before the joint cartridge is inserted into the receptacle or before the structural part is joined with the joint cartridge. Preferably the coating of the joint cartridge and the structural part is different. In particular, the joint cartridge and the structural part are provided with coatings independently of one another. Preferably the joint cartridge and the structural part are coated by different coating methods. Coatings are used in particular to protect joint cartridges or structural parts from environmental influences such as contamination and moisture. The coating is preferably a protective coating. Preferably the joint cartridge is coated and then preassembled into the joint.

The structural part is preferably coated by dip coating, in particular cathode dip coating. For example, the structural part is coated with a lacquer comprising, for example, an organic material. The joint cartridge is preferably galvanically coated. For example, a zinc-iron coating is provided on the joint cartridge.

Preferably, the structural part precoated on the outer surface is permanently fixed by means of a material-bonded joint method with a joint cartridge precoated on the outer surface and preassembled into the joint. Since the joint cartridge already preassembled with the joint is combined with the structural part, the assembly of the individual parts of the joint to the structural part is omitted. As a result, when incorporating a joint into a structural part, a tolerance reduction can be achieved compared to DE 603 04 709 T2. In addition, since the joint cartridge is joined with the structural part by the material-bonded joint method, the joining process of the joint cartridge and the structural part can be made with a low tolerance. Due to this, higher accuracy can be obtained than by press-fitting, screwing or niveting the joint in or on the structural part. Finally, since the joint cartridge and the structural part are already precoated, different coatings of the joint cartridge and the structural part are possible in a simple way, since the joint cartridge and the structural part can be precoated independently of each other. In addition, the handling of the parts to be joined together is simplified, since the assembler does not hesitate to contact the joint cartridge and structural parts without having to perform cleaning of the parts, which may be necessary because of contamination due to contact before the coating process. This can be fixed.

The precoated structural part and the precoated joint cartridge are preferably pretreated for the material bonded joint method. In particular, precoated structural parts and joint cartridges precoated with precoated joints are pretreated for the material bonded joint method. Preferably the precoating of the joint cartridge, in particular of the joint cartridge pre-assembled with the joint, is partially removed prior to the implementation of the material-bonded joint method, resulting in uncoated areas of the joint cartridge. Preferably the coating removal area of the joint cartridge is joined with the structural part by a material bonded joint method. Partial removal of the precoating of the joint cartridge is preferably done by laser coating removal or other coating removal method.

In particular, since the precoating of the structural part is partially removed prior to the implementation of the material bonded joint method, an uncoated area is formed in the structural part. Preferably the uncoated area of the structural part is joined with the joint cartridge by a material bonded joint method. It has been shown that partial coating removal of precoated joint cartridges and precoated structural parts can be carried out at lower cost than material bonded joints of uncoated joint cartridges and uncoated structural parts. This is because uncoated parts generally have to be cleaned and coated after bonding.

According to an improvement of the present invention, a joint accommodating part is formed in a precoated structural part, and a joint cartridge precoated in the joint accommodating part and preassembled into a joint is inserted. In particular, a joint receptacle is formed in the precoated structural part, and within the joint receptacle, a joint cartridge precoated and preassembled into a joint is inserted before the execution of the material-bonded joint method. Preferably the joint cartridge is inserted into the joint receptacle in the axial direction. Partial removal of the precoating of the structural part is preferably made during formation of the joint receptacle.

Preferably the joint receptacle is formed by beam cutting, in particular laser beam melt cutting. Since beam cutting can be carried out with very small tolerances, the formation and positioning of the joint receptacle in the structural part is made with high accuracy.

Preferably the joint cartridge is inserted into the joint receptacle in the axial direction. The joint receptacle is preferably formed with a rounded, unrounded, rectangular, rectangular or polygonal circumferential contour. This contour may in particular be an inner circumferential contour surrounding the joint cartridge after the joint cartridge has been inserted into the joint receptacle. The circumferential contour of the joint receptacle is preferably matched to the outer circumferential contour of the joint cartridge. Thus, the joint cartridge is also preferably formed in a rounded, unrounded, rectangular, rectangular or polygonal circumferential contour. By being formed with a non-round or polygonal circumferential contour, shape-fitting rotation prevention can be realized in addition to material-bonded joining. Further, with the polygonal circumferential contour, the rotational position of the joint cartridge with respect to the axial direction can be given in advance. In contrast, the rounded circumferential contour has the advantage that the assembler can insert the joint cartridge into the joint receptacle at any rotational position relative to the axial direction. The engagement between the joint cartridge and the structural part, preferably formed by the material-bonded joint method, is strong enough to form sufficient anti-rotation.

The joint receptacle preferably comprises a recess into which the joint cartridge is inserted. According to an improvement of the invention, the joint receptacle comprises a hole extending through the structural part or forms the hole, in which a joint cartridge is inserted. The recess in the joint receptacle is in particular formed in a hole. Preferably the hole extends through the structural part in the axial direction. Continuous holes can be formed with high accuracy by the beam cutting method described above in a simple manner.

The joint cartridge preferably has a radial shoulder and the shoulder rests on the structural part when the joint cartridge is inserted into the joint receptacle in the axial direction. The shoulder is in particular in contact with the edge of the joint receptacle. Preferably the shoulder has a longer length in the radial direction than the joint receptacle or hole. By placing the shoulder on the structural part, a positioning aid is formed when the joint cartridge is inserted into the joint receptacle in the axial direction. The shoulder is especially the outer shoulder. Preferably the shoulder is an annular shoulder. Preferably the joint cartridge has an annular collar on its outer circumferential surface and a shoulder is formed on the collar. The expression "radiation direction" especially refers to any direction extending perpendicular to the axial direction.

According to an improvement of the invention, the outer circumferential surface of the joint cartridge is formed at least partially tapered in the axial direction. For example, the outer peripheral surface is at least partially formed conical in the axial direction. The tapered or conical design of the outer circumferential surface of the joint cartridge is preferably used for centering the joint cartridge during insertion of the joint cartridge into the joint receptacle. Thus, possible tolerances can be compensated for, for example, in the diameter of the joint receptacle.

The joint is in particular a ball joint or forms a ball joint. Preferably the joint internal part forms a ball pin with a ball, the ball of which is inserted into the joint cartridge and movably supported in the joint cartridge prior to the engagement of the structural part with the joint cartridge. The ball of the ball pin is in particular rotatably and / or pivotally supported in the joint cartridge. Preferably the ball pin extends from the joint cartridge through the joint cartridge opening. According to an improvement of the invention, the ball pin is slidably supported in the bearing shell, which bearing shell is inserted into the joint cartridge and is preferably made of plastic.

The wall of the joint cartridge in the region of the joint cartridge opening is preferably deformed, in particular warped in the direction of the ball pin. In this case, the area to be deformed of the wall preferably does not have a precoating of the joint cartridge, because otherwise the precoating in this area may peel off. According to an alternative, the wall of the joint cartridge in the region of the joint cartridge opening may be preformed in the direction of the ball pin. According to another alternative, the joint cartridge opening may be covered with a closure ring, which closure ring is fixed to the joint cartridge, through which the ball pin extends. By deformation of the wall of the joint cartridge in the region of the joint cartridge opening, smaller tolerances can be obtained than by the closing ring, since no additional parts are needed. Since the preformed or deformed area of the closing ring or wall covers the joint ball, preferably in the axial direction, the ball pin is fixed to the joint cartridge in the axial direction and in particular may not be drawn out of the joint cartridge. The deformation of the wall of the joint cartridge in the area of the joint cartridge opening, or the fastening of the closing ring to the joint cartridge, is preferably made before the joining of the structural part and the joint cartridge.

According to an embodiment of the invention, the ball pin is inserted into the joint cartridge through the joint cartridge opening, in particular before the wall of the joint cartridge in the region of the joint cartridge opening is deformed in the direction of the ball pin or the closing ring is fixed to the joint cartridge. do.

According to another embodiment of the present invention, the joint cartridge has an assembly opening opposite the joint cartridge opening, through which the ball pin is inserted into the joint cartridge. This is especially the case when the wall of the joint cartridge in the region of the joint cartridge opening is preformed in the direction of the ball pin. After the ball pin is inserted into the joint cartridge, in particular before the structural part is engaged with the joint cartridge, the assembly opening is preferably closed with the housing cover.

Bonding areas formed by the material-joined joint method, in particular welding areas formed by welding, are preferably covered by sealing bellows. This has the advantage that the joining area or the welding area need not be protected by the coating for protection from environmental influences, so that the provision of such a coating can be omitted. The sealing bellows can preferably be in particular a sealing bellows of the joint which simultaneously seals the joint cartridge openings. Preferably the joint inner part extends through the sealing bellows, which in particular lies in a sealing manner in the joint inner part and in the joint cartridge or structural part. The sealing bellows may preferably be made of a flexible material. Preferably the sealing bellows consists of an elastomeric material, in particular rubber.

The structural part is preferably made of metal. The joint cartridge is also preferably made of metal.

According to an improvement of the invention, at least one further joint receptacle is formed in the structural part, and the further joint is inserted into the further joint receptacle and fixedly coupled with the structural part. Preferably after the joint or one other joint or a plurality of other joints is fixedly coupled with the structural part, an additional joint receptacle is formed in the structural part. In particular, the point at which the additional joint receptacle is formed in the structural part is determined in accordance with the position of the joint which is in fixed engagement with the structural part or in accordance with the position (s) of the other joint (s) in fixed engagement with the structural part. Thus, multiple joint receptacles can be positioned in the structural part with high accuracy.

 The additional joint receptacle can be formed in the same way as the joint receptacle. In particular, the further joint receptacle comprises or forms a hole extending through the structural part, and an additional joint is inserted into the hole.

By means of the invention, the integration of the joints in the structural part is achieved with high accuracy.

1 to 7 show several views of a chassis component 1 formed as a three point link, according to an embodiment of the invention, wherein the ball joint 2 is integrated into the structural component 3. The structural part 3 is fixedly engaged with two rubber bearings 27 and 28 used to connect the chassis part 1 to the vehicle body of the motor vehicle. The ball joint 2 is preferably used to connect the chassis component 1 to the wheel carrier.

The ball joint 2 comprises a joint cartridge 5 used as a joint housing (see FIG. 3), and the ball pin 6 is supported in the joint cartridge 5 so as to be rotatable and pivotable. The ball pin 6 extends from the joint cartridge 5 through the joint cartridge opening 7. The joint cartridge opening 7 is sealed by a sealing bellows 8, and the ball pin 6 extends through the sealing bellows 8. The longitudinal central axis 9 of the ball joint 2 extends in the axial direction 10. A cross-sectional view of the chassis component 1 along the longitudinal central axis 9 is shown in FIG. 7.

The ball pin 6 comprises a ball 11 which forms an axial end of the ball pin 6 and is slidably supported in a bearing shell 12 which is preferably made of plastic. . The bearing shell 12 is placed in the inner chamber 13 of the joint cartridge 5 together with the ball 11 and does not rotate about the longitudinal central axis 9 in the joint cartridge 5. In addition, the wall 14 of the joint cartridge 5 defining the inner chamber 13 in the region of the joint cartridge opening 7 is deformed in the direction of the ball pin 6. Thus, the wall 14 covers the bearing shell 12 and the ball 11 in the axial direction 10 in the region of the joint cartridge opening 7 so that the ball pin 6 and the bearing shell 12 are joint cartridges. It is fixed in the axial direction 10 in (5). Far from the joint cartridge opening 7, the side of the bearing shell 12 contacts the wall 14.

The joint cartridge 5 lies in a joint receptacle 15 formed as a hole extending through the structural part 3 in the axial direction 10. The joint cartridge 5 comprises an annular radial collar 16 defining a radially outer shoulder 17 (see FIG. 5), the joint cartridge 5 being axially oriented by the radially outer shoulder 17. The structural part 3 is contacted with (10). Thus, the collar 16 secures the joint cartridge 5 to the structural component 3 in the axial direction 10. In addition, the joint cartridge 5 is welded with the structural part 3, the associated welding seam being indicated by reference numeral 18. The welding seam 18 is preferably formed in an annular shape. The weld seam is formed in a 360 ° annulus, but it is not necessary.

One axial end of the sealing bellows 8 surrounding the joint cartridge 5 is in sealing contact with the joint cartridge 5 and the structural part 3 and covers the weld seam 18. In addition, the other axial end of the sealing bellows 8 surrounding the ball pin 6 is in sealing contact with the ball pin 6. Thus, the joining area of the ball joint 2 and the structural part 3 is protected from environmental influences. The circumferential contour 19 (hole wall; see FIG. 5) of the structural part 3 defining the joint receptacle 15 contacts the joint cartridge 5 in the radial direction, so that the radially acting force is optimally viewed. It can be transferred from the joint 2 to the structural part 3 and vice versa.

Hereinafter, the manufacturing method of the chassis component 1 according to the present invention will be described. First, the structural part 3 and the ball joint 2 shown alone in FIG. 3 are manufactured independently of each other. The sealing bellows 8 is not yet mounted on the ball joint 2. Thereafter, the ball pin 6 of the ball joint 2 is first in the axial direction 10 until the shoulder 17 of the collar 16 contacts the structural component 3 in the axial direction 10, It is inserted into the joint receptacle 15. This state is shown in FIGS. 4 and 5 showing the ball joint 2 inserted into the joint receiving portion 15 before welding of the joint cartridge 5 and the structural part 3. 5 shows a partial cross-sectional view of the ball joint 2 along the longitudinal central axis 9.

While the ball joint 2 is inserted into the joint receptacle 15 of the structural part 3, the joint cartridge 5 is preferably radially centered by the curved area of the wall 14. The centering is shown schematically in FIG. 8, which is a cross sectional view of the ball joint 2 along the longitudinal central axis 9. In the region of the joint cartridge opening 7 the deformed region of the wall 14 extends to the region tapering in the axial direction 10 of the outer circumferential surface 20 of the joint cartridge 5 and the joint cartridge 5 opens in the joint cartridge opening. Since it is first inserted into the joint receptacle 15 of the structural part 3 into the area of the wall 14 defining (7), the joint cartridge 5 is formed by the interaction of the circumferential contour 19 and the outer circumferential surface 20. ) Radial centering is achieved. 8 shows the structural part 3 twice. In the first state I, the joint cartridge 5 is positioned in the joint cartridge 5 by the tapered area of the outer circumferential surface 20. As the joint cartridge 5 is further inserted into the joint accommodating portion 15 in the axial direction 10, the interaction between the circumferential contour 19 and the outer circumferential surface 20 is such that the joint cartridge 5 is connected to the joint accommodating portion 15. Until it is radially centered within. The joint cartridge 5 is inserted in the axial direction 10 into the joint receptacle 15 until the shoulder 17 contacts the collar 16 to the structural part 3. This state is indicated by II. In order to improve radial centering, the outer circumferential surface 20 of the joint cartridge 5 may further be formed partly conical in the axial direction 10, which shows a variant embodiment of the joint cartridge 5. 9 and FIG. 10. According to a variant embodiment, the outer circumferential surface 20 comprises a region 21 extending conically in the axial direction 10, which region 21 during insertion of the joint cartridge 5 into the joint receptacle 15. It is in contact with the circumferential contour 19. Because of this, since the joint cartridge 5 is fixed axially to the structural part 3, the radial collar 16 with the shoulder 17 can be omitted in accordance with a variant embodiment. FIG. 9 shows a state in which the joint cartridge 5 is only partially inserted into the joint accommodating part 15, while FIG. 10 shows a state in which the joint cartridge 5 is fully inserted into the joint accommodating part 15. .

After the joint cartridge 5 is fully inserted into the joint receiving portion 15 of the structural part 3, a welding seam 18 is formed by laser beam welding (see FIG. 6) and then the sealing bellows 8 Is mounted on the ball joint 2.

Prior to welding the structural part 3 and the joint cartridge 5, a coating 22 or 23 is provided on the outer surface of the structural part 3 and the joint cartridge 5, respectively, and the joint cartridge 5 and the structural part ( Prior to welding of 3), the coating 23 in the area 24 is removed again by laser coating removal. The coating 23 is provided on the outer surface of the joint cartridge 5 before insertion of the ball pin 6 into the joint cartridge 5, but in the axial end region of the joint cartridge 5 surrounding the joint cartridge opening 7. 25 is not provided with a coating 23. Since the end region 25 deforms after insertion of the bearing shell 12 and the ball 11, the coating in the region 25 may peel off during deformation. Also, before the joint receptacle 15 is formed, a coating 22 is provided to the structural part 3. After the coating 22 is provided to the structural part 3, the joint receptacle 15 is formed in the structural part 3 by laser beam cutting. This removes the coating 22 in the edge region 26 of the structural part 3 surrounding the joint receptacle 15. The parts 2 and 3 thus prepared can be inserted into each other as described above, after which the coating removal areas 24 and 26 are joined to each other under the formation of a welding seam 18 by laser beam welding. Can be. After mounting of the sealing bellows 8, the weld seams 18, the remaining portions of the areas 24 and 26 and the end area 25 are protected from environmental influences by the sealing bellows 8.

2 shows a plan view of the structural part 3, bearings 27 and 28 being fixedly coupled with the structural part 3. According to the invention only after the joining of the structural part 3 and the bearings 27 and 28, the joint receptacle 15 is formed. The point 29 at which the joint receptacle 15 is formed depends on the positions 30 and 31 of the rubber bearings 27 and 28 which are already fixedly coupled with the structural part 3. The positions 30 and 31 of the rubber bearings 27 and 28 are in particular marked by their kinematic points. In addition, the point 29 preferably represents the position of the kinematic point of the ball joint 2 in a fixed engagement with the structural part 3. In particular, the point 29 represents the center point of the joint receptacle 15. After the point 29 has been determined, the joint receptacle 15 is formed in the structural part 3 by laser beam cutting, and at the same time the area 26 in which the surface coating 22 of the structural part 3 surrounds the joint receptacle. Is removed).
