[0004] Replacement part, replacement part device with such a replacement part and method for inserting a replacement part

[0005] The invention relates to a replacement part, a replacement part device with a housing and a replacement part that can be arranged interchangeably in the housing, and a method for inserting a replacement part into a housing.

[0006] These types of exchangeable parts are designed to be inserted into a housing and removed from it – either at a predetermined replacement interval or as needed. For example, such an exchangeable part could be a filter that is changed either at regular intervals or depending on the actual load. Typically, these exchangeable parts are inserted into the housing using a combined translational and rotational insertion motion. In the final phase of this motion, they are pivoted into their final position, where a safety mechanism, pre-tensioned during insertion, engages a notch in the housing to secure the exchangeable part. To remove the exchangeable part, the safety mechanism is manually released from the notch.This design is problematic in two respects: Firstly, there is a risk that a seal of the replacement part may become jammed due to the rotational component of the insertion movement, potentially causing damage or preventing it from reaching its correct position in the predetermined end position; secondly, the grid recess protrudes unfavorably into the interior of the housing, where it forms a disruptive geometry that can, for example, impede the flow of a medium to be filtered.

[0007] The invention is therefore based on the objective of providing a replacement part, a replacement part device with a housing and a replacement part that can be arranged interchangeably in the housing, as well as a method for inserting a replacement part into a housing, wherein the aforementioned disadvantages are at least partially avoided, preferably avoided. 2024P00498WG

[0009] October 24, 2025

[0010] The problem is solved by providing the present technical teaching, in particular the teaching of the independent claims as well as the preferred embodiments disclosed in the dependent claims and the description.

[0011] The problem is solved, particularly in a first aspect, by creating an interchangeable part for insertion and fixing in a housing. A locking bar for fixing the interchangeable part in the housing is pivotably arranged on a base body of the interchangeable part about a pivot axis, and the locking bar projects from the base body. Advantageously, unlike the known safety mechanism pre-tensioned during insertion, the locking bar can be pivoted about the pivot axis before or during insertion to such an extent that the interchangeable part can be inserted into the housing in a purely translational insertion motion, without tilting or jamming. Once the interchangeable part reaches its predetermined end position, the locking bar can be rotated—especially manually—into a locking position, in which it secures the interchangeable part in the housing.For removal, the locking tab can again be rotated out of the locked position – preferably manually – and the replacement part can then be removed from the housing in a purely translational removal motion. This advantageously prevents the seal of the replacement part from becoming jammed, allowing it to be removed undamaged from its sealing end position. Alternatively or additionally, securing the locking tab, particularly for providing the locking position, does not require a protruding notch in the housing, so the housing is free of any interfering geometry and / or has an advantageously small installation space.

[0012] If the replacement part is manufactured at least partially by foaming, a further advantage is that it can be removed vertically from a foaming tool.

[0013] In one embodiment, the insertion movement of the replacement part comprises a first translational component and a second translational component, wherein the second translational component is preferably perpendicular to the first translational component, and wherein the second translational component follows the first translational component in time. The components thus do not form a superimposed movement, but are realized sequentially. In particular, the replacement part is first inserted into the housing along a first direction and then moved into its final position along a second direction, which is particularly perpendicular to the first direction. (See 2024P00498WG.)

[0014] Daimler Truck AG 3 Dr. Britta Riege

[0015] October 24, 2025

[0016] Insertion movement preferably free of any rotating component; in particular, the replacement part is not rotated or tilted.

[0017] The pivot axis preferably extends perpendicular to a longitudinal direction of the replacement part. A longitudinal direction of the replacement part is preferably understood to be the direction of its longest extension or extent.

[0018] The locking bar is movable, in particular in a pivoting circumferential direction around the pivot axis, wherein the pivoting circumferential direction is everywhere perpendicular to the pivot axis and at least locally perpendicular to the longitudinal direction of the replacement part.

[0019] In one embodiment, the locking bar is pivotally connected to the base body of the replacement part about the pivot axis.

[0020] The locking bar can be formed in one piece, particularly of a single material, with at least one area of ​​the base body of the replacement part, especially if the pivot axis is formed by a film hinge. Alternatively, the locking bar can be formed in multiple parts with the base body, for example, clipped to it or otherwise positively, frictionally, or materially bonded.

[0021] In particular, the locking bar is designed to fix the replacement part in the housing.

[0022] According to a further development of the invention, the locking bar is arranged on the base body so as to be pivotable about the pivot axis without any preload. This particularly allows for smooth, purely translational insertion of the replacement part into the housing. "Without preload" here means, in particular, that the locking bar is neither preloaded into a predetermined position nor preloaded during or by the insertion movement. Specifically, the locking bar has a spring constant that is at most negligible, preferably non-existent, in the area of ​​its connection with the base body, especially in the area of ​​the pivot axis; that is, the locking bar is not resiliently attached to the base body.

[0023] According to a further development of the invention, the locking bar is hinged to the base body. This represents an advantageous and reliable design for hinged the locking bar to the base body. 2024P00498WG

[0024] Daimler Truck AG 4 Dr. Britta Riege

[0025] October 24, 2025

[0026] In one embodiment, the hinge is designed as a film hinge. In this configuration, the replacement part is particularly inexpensive to manufacture. Preferably, the locking bar is a single piece in this case, and in particular, it is formed from a single material, at least with a portion of the base body.

[0027] Alternatively, the hinge can be designed as a fork hinge. In this configuration, the replacement part can be particularly robust. Preferably, the locking bar is formed in multiple parts with the base body, so that the base body and the locking bar can be easily optimized with regard to their respective functions.

[0028] According to a further development of the invention, the locking bar is engaged with a detent geometry on a counter-detent geometry of the base body, the detent geometry and the counter-detent geometry together forming the hinge. This represents a design that is easy to manufacture and assemble, yet very reliable in its function.

[0029] According to a further development of the invention, the replacement part has a seal on a first end face for tight contact with a sealing housing wall of the housing, with the locking rib being arranged on a second end face opposite the first end face. Particularly in this case, damage to the seal due to tilting can be advantageously avoided, and / or it can be ensured that the seal reliably reaches its final position. The second end face is located opposite the first end face along the longitudinal direction of the replacement part. The seal can be manufactured, for example, by foaming.

[0030] According to a further development of the invention, the replacement part is designed as a filter. This particularly realizes the advantages already mentioned.

[0031] According to a further development of the invention, a flow-permeable filter wall of the filter extends along the longitudinal direction between the first end face and the second end face. The medium to be filtered preferably enters the filter laterally, between the end faces, through the flow-permeable filter wall.

[0032] Preferably, the filter wall is closed in the circumferential direction. In particular, it encloses a hollow interior of the base body. Specifically, the substance to be filtered (2024P00498WG)

[0033] Daimler Truck AG 5 Dr. Britta Riege

[0034] October 24, 2025

[0035] The medium flows along the circumference of the exchange part, through the filter wall, and into the hollow interior of the base body. Preferably, the filter wall forms a filter material body between the end faces, which are designed as end plates.

[0036] The replacement part, designed as a filter, in particular as a filter element, comprises in one embodiment a hollow cylindrical filter body formed from the filter wall and two end plates forming the first and second end faces. The first end plate has a filter opening with which the replacement part can be tightly fitted onto a clean air port of the housing. The locking rib is pivotably arranged on the second end plate about the pivot axis, in particular either integrally formed with the second end plate, preferably of the same material, or attached to the second end plate. The end plates, in particular the first end plate with the seal, can be manufactured, for example, by foaming.

[0037] The problem is also solved in a second aspect by creating an exchangeable part device comprising a housing and an exchangeable part according to the invention, or an exchangeable part according to one or more of the previously described embodiments, which can be arranged interchangeably in the housing. The housing has a locking recess, wherein the locking bar and the locking recess are aligned such that the locking bar engages in the locking recess and can thus fix the exchangeable part in the housing when the exchangeable part is arranged in the housing. The exchangeable part device offers, in particular, those advantages that have already been explained in connection with the exchangeable part.

[0038] In one embodiment, the locking recess is arranged in a locking housing wall.

[0039] Preferably, the resting recess is formed in the resting housing wall.

[0040] The housing preferably has a maintenance closure, in particular a cover, which is designed to open or close a maintenance opening in the housing as needed. With the maintenance opening open, the replacement part can be removed from the housing and inserted into the housing, i.e., generally, replaced.

[0041] The locking housing wall preferably lies opposite the sealing housing wall of the housing along the longitudinal direction. The sealing housing wall is configured as follows: 2024P00498WG

[0042] Daimler Truck AG 6 Dr. Britta Riege

[0043] 24.10.2025 that the seal of the replacement part can be in a sealing position against the seal housing wall when the replacement part is inserted into the housing and fixed by means of the locking bar.

[0044] According to a further development of the invention, the housing has an inlet opening and an outlet opening for fluid flow, and the exchange part can be arranged in the housing such that the fluid flow passes through the exchange part from the inlet opening to the outlet opening. Preferably, a normal vector of the inlet opening and a normal vector of the outlet opening are oriented obliquely to each other, in particular they are perpendicular to each other.

[0045] In one embodiment, the housing – preferably designed as a filter housing – has an inlet opening through which a medium to be filtered can flow into the housing and an outlet opening through which the medium to be filtered can flow out of the housing, particularly when the replacement part is designed as a filter.

[0046] Preferably, the maintenance closure – which is designed in particular as a cover – has the inlet opening.

[0047] In one embodiment, the housing has the outflow opening on the sealing housing wall.

[0048] Preferably, the sealing housing wall has a clean air port that projects into the interior of the housing and is arranged and configured to penetrate the seal of the replacement part when the replacement part is positioned in the housing and secured by the locking bar. The seal then rests against the clean air port, particularly along a closed circumferential line. The clean air port forms a flow-related connection to the hollow interior of the replacement part, which is designed, in particular, as a filter. Simultaneously, the clean air port forms the outlet opening.

[0049] Preferably, the medium to be filtered can flow into the housing through the inlet opening, where it flows through the filter wall into the hollow interior of the exchange part designed as a filter, from where it can then flow out of the housing via the clean air nozzle and the outlet opening.

[0050] The problem is also solved in a third aspect by methods for inserting a replacement part according to the invention or a replacement part according to one or more of the previously 2024P00498WG

[0051] Daimler Truck AG 7 Dr. Britta Riege

[0052] The embodiments described in 24.10.2025 are created in a housing, in particular in a housing of an exchangeable part device according to the invention or an exchangeable part device according to one or more of the previously described embodiments, wherein the exchangeable part is inserted into the housing - purely translationally - in a position that is aligned parallel to a bottom surface of the housing connecting the locking housing wall and the sealing housing wall, wherein - simultaneously with this translational insertion movement along an insertion direction - the locking bar is guided along the locking housing wall in a rotated position, wherein the exchangeable part - subsequently, in particular after stopping at the bottom surface, i.e. when it rests against the bottom surface - is moved in the direction of the sealing housing wall, and wherein - again subsequently,especially when the seal of the replacement part rests against the sealing housing wall - the locking tab is turned into a locking position and inserted into the detent recess of the detent housing wall, in particular, it is engaged.

[0053] The fact that the replacement part is inserted into the housing in a position parallel to the bottom surface of the housing – purely translationally – means, in the context of the present technical teaching, in particular that the longitudinal direction of the replacement part is aligned parallel to the bottom surface while the replacement part is being inserted into the housing.

[0054] The term "rotated position" of the locking bar refers specifically to a position in which the locking bar is rotated around the pivot axis such that it protrudes less from the base body than in the locked position, thus reducing the longitudinal length of the replacement part, including the locking bar, compared to the locked position. In this rotated position of the locking bar, the replacement part can be inserted, in particular placed, or fitted into the housing without tilting or jamming.

[0055] When the replacement part is lying on the bottom surface, it is preferably moved perpendicular to the insertion direction - again translationally in a fixing direction - in the direction of the sealing housing wall, until the seal of the replacement part rests against the sealing housing wall.

[0056] The insertion movement thus consists of two successive, purely translational – and preferably perpendicular – displacements: an insertion movement along the insertion direction and a fixing movement along the fixing direction. 2024P00498WG

[0057] Daimler Truck AG 8 Dr. Britta Riege

[0058] October 24, 2025

[0059] The locking position of the locking lug is, in particular, a rotationally extended position compared to the engaged rotational position, in which the longitudinally measured length of the replacement part, including the locking lug, is longer than in the engaged rotational position; thus, the locking lug protrudes further from the base body. Preferably, the replacement part is pressed even further towards the seal housing wall by the rotation and engagement of the locking lug, so that the seal rests tightly against the seal housing wall when the locking lug engages in the locking recess.

[0060] Preferably, the locking bar is manually turned into the rotated position and also manually inserted into the locking recess. Since the locking bar is preferably not pre-tensioned, it does not enter the locking recess on its own or automatically.

[0061] In one embodiment, the maintenance closure, in particular the cover, is opened, then an optional replacement part already present in the housing is removed, subsequently the - new - replacement part is inserted into the housing as described, and then the maintenance closure is closed.

[0062] The invention will be explained in more detail below with reference to the drawing. The drawing shows:

[0063] Figure 1 shows a representation of a first embodiment of a replacement part;

[0064] Figure 2 shows a detailed representation of a second embodiment of a replacement part;

[0068] Replacement part into a housing of a replacement part device.

[0069] Figure 1 shows a representation of a first embodiment of a replacement part 1 in a longitudinal section.

[0070] The replacement part 1 is designed to be inserted into a housing 3 – see Figure 4 – and fixed in the housing 3. It has a base body 5 on which a locking bar 7, designed to fix the replacement part 1 in the housing 3, is pivotably arranged about a pivot axis A, the locking bar 7 projecting from the base body 5. The pivot axis A preferably extends perpendicular to a longitudinal direction L of the replacement part 1. The locking bar 7 is, in particular, pivotable in a circumferential direction U about the 2024P00498WG

[0071] Daimler Truck AG 9 Dr. Britta Riege

[0072] October 24, 2025

[0073] Swivel axis A is movable, being oriented everywhere perpendicular to the swivel axis A and at least locally perpendicular to the longitudinal direction L of the exchange part 1.

[0074] The locking web 7 is preferably pivotally connected to the base body 5 about the pivot axis A without preload. In particular, the locking web 7 has a spring constant that is at most negligible, preferably non-existent, in the area of ​​its connection with the base body 5, i.e., in the area of ​​the pivot axis A; that is, the locking web 7 is not resiliently arranged on the base body 5.

[0075] The replacement part 1 is preferably designed as a filter, in particular as a filter element. The base body 5 is preferably formed from a hollow cylindrical filter material body 8, which forms a flow-permeable filter wall 9 closed in the circumferential direction and extends between two end plates 11 opposite each other in the longitudinal direction L, namely a first end plate 11.1 and a second end plate 11.2. The first end plate 11.1 forms a first end face 13.1 of two end faces 13, which has a seal 15 and a filter opening 17. The barrier 7 is arranged on a second end face 13.2 of the two end faces 13 formed by the second end plate 11.2.

[0076] In the first embodiment, the locking web 7 is formed in one piece, in particular of a single material, with at least one area of ​​the base body 5, in particular with the second end plate 11.2. The pivot axis A is formed by a hinge 21, here designed as a film hinge 19.

[0077] The filter body 8 is preferably supported and held by a perforated support structure 20.

[0078] Figure 2 shows a representation of a second embodiment of the replacement part 1.

[0079] Identical and functionally equivalent elements are provided with the same reference symbols in all figures, so that reference is made to the preceding description in each case.

[0080] In the second embodiment, the locking bar 7 is formed in multiple parts with the base body 5, in particular clipped to it. The hinge 21 is designed as a fork hinge 22. The locking bar 7 has a detent geometry 23, which is cylindrical in this case, and engages with a counter-detent geometry 25 of the 2024P00498WG, which is designed as a fork.

[0081] Daimler Truck AG 10 Dr. Britta Riege

[0082] October 24, 2025

[0083] The base body 5 can be locked in place, with the locking geometry 23 and the counter-locking geometry 25 together forming the hinge 21.

[0084] Figure 3 shows a representation of a third embodiment of the exchange part 1.

[0085] In the third embodiment, the locking bar 7 is also formed in multiple parts with the base body 5, in particular clipped to it. Here too, the hinge 21 is designed as a fork hinge 22. However, the locking bar 7 has the detent geometry 23, which is now designed as a fork and can be engaged with the cylindrically designed counter-detent geometry 25 of the base body 5, with the detent geometry 23 and the counter-detent geometry 25 together forming the hinge 21.

[0086] Figure 4 shows an embodiment of an exchangeable part device 27.

[0087] This includes the housing 3 and the interchangeable part 1 which can be arranged in the housing 3 according to one of the previously described embodiments - here as specifically shown according to the first embodiment.

[0088] In a) an exploded view of the exchange part device 27 is shown, in b) a longitudinal section of the housing 3.

[0089] The housing 3 has a locking recess 29, wherein the locking rib 7 and the locking recess 29 are aligned such that the locking rib 7 engages in the locking recess 29 and can thus secure the replacement part 1 in the housing 3 when the replacement part 1 is arranged in the housing 3. The locking recess 29 is preferably arranged in a locking housing wall 31, and is particularly well designed in this configuration.

[0090] The housing 3 preferably also has a maintenance closure 33, in particular a cover 35, which is designed to open or close a maintenance opening 37 of the housing 3 as needed. With the maintenance opening 37 open, the replacement part 1 can be removed from the housing 3 and inserted into the housing 3, i.e., generally exchanged.

[0091] The locking housing wall 31 preferably lies opposite a sealing housing wall 39 of the housing 3 along the longitudinal direction L. The sealing housing wall 39 is designed such that the seal 15 of the replacement part 1 seals against the sealing wall. 2024P00498WG

[0092] Daimler Truck AG 11 Dr. Britta Riege

[0093] October 24, 2025

[0094] housing wall 39 can be in contact when the replacement part 1 is inserted into the housing 3 and fixed by means of the locking bar 7.

[0095] Furthermore, the housing 3 – preferably designed as a filter housing – preferably has an inlet opening 41 and an outlet opening 43 for fluid flow, wherein the exchange part 1 can be arranged in the housing 3 such that the fluid flow passes from the inlet opening 41 to the outlet opening 43 through the exchange part 1. In the illustrated embodiment, a normal vector of the inlet opening 41 and a normal vector of the outlet opening 43 are perpendicular to each other, thus deflecting the fluid flow within the housing 3. In particular, the maintenance closure 33 has the inlet opening 41. The outlet opening 43 is formed on the sealing housing wall 39.

[0096] Furthermore, the sealing housing wall 39 preferably has a clean air port 45 that projects into the interior of the housing 3 and is arranged and configured to penetrate the seal 15 of the exchange part 1 when the exchange part 1 is arranged in the housing 3 and fixed by the locking bar 7. The seal 15 then seals against the clean air port 45. The clean air port 45 also forms a flow connection to a hollow interior of the exchange part 1. In addition, the clean air port 45 forms the outlet opening 43. The medium to be filtered can thus flow into the housing 3 through the inlet opening 41, where it is filtered by the filter wall 9 and flows into the hollow interior of the exchange part 1, from where it can again flow out of the housing 3 via the clean air port 45 and the outlet opening 43.

[0097] Figure 5 shows an embodiment of a method for inserting the replacement part 1 into the housing 3 of the replacement part device 27.

[0098] As shown in a), the replacement part 1 is inserted into the housing 3 – purely translationally – in a position parallel to a base surface 47 of the housing 3 connecting the locking housing wall 31 and the sealing housing wall 39, along an insertion direction – here vertically downwards – with the locking lug 7 – see also in b) – being guided along the locking housing wall 31 in a rotated position. The replacement part 1 is then – again purely translationally, see b) and c) – particularly once it has come into contact with the base surface 47, moved along a fixing direction perpendicular to the insertion direction towards the sealing housing wall 39, until the seal 15 of the replacement part 1 is against the sealing housing wall 39. 2024P00498WG

[0099] Daimler Truck AG 12 Dr. Britta Riege

[0100] 24.10.2025. When the seal 15 rests against the seal housing wall 39, the locking rib 7 is rotated into a locking position and inserted into the detent recess 29 of the detent housing wall 31, in particular, engaged. The insertion movement for the replacement part 1 consists of two purely translational displacements of the base body 5, namely an insertion movement along the insertion direction and a fixing movement along the fixing direction.

[0101] As shown in d) and e), the locking lug 7 is preferably inserted manually into the detent recess 29. In particular, the replacement part 1 is pushed even further towards the sealing housing wall 39 by rotating it into the locking position and engaging the locking lug 7, so that the seal 15 finally rests tightly against the sealing housing wall 39 when the locking lug 7 engages in the detent recess 29.

[0102] Preferably, the maintenance closure 33 is opened, then optionally a replacement part 1 already present in the housing 3 is removed via the maintenance opening 37, subsequently the new replacement part 1 is inserted into the housing 3 via the maintenance opening 37 as described, and then the maintenance closure 33 is closed again.

[0103] The insertion movement is, in particular, free of any rotational component; specifically, the replacement part 1 is neither rotated nor tilted. Since the seal 15 and the corresponding geometries of the housing 3 are thus aligned during the fixing movement, tilting of the seal 15 is advantageously avoided, allowing it to reach its sealing end position undamaged. Furthermore, no notch projecting into the interior of the housing 3 is required to secure the locking lug 7, so the housing 3 is free of any interfering geometry.
