ARRANGEMENT FOR ATTACHING A CONTROL DEVICE TO THE BODY OF AN AGRICULTURAL MACHINE

Description

[0001] The present application relates to an arrangement for attaching a control unit to a body of an agricultural machine, in particular a tractor, according to the preamble of independent claim 1, and to an agricultural machine, in particular a tractor, with a control unit and such an arrangement for attaching a control unit to a body of an agricultural machine according to claim 13.

[0002] Agricultural machinery includes one or more control units that process various data necessary for carrying out a work order, enabling the appropriate control of the machine's working units. These control units—also known as electronic control units (ECUs)—are subjected to considerable stress during operation. When performing agricultural tasks on uneven terrain or farmyards, the machinery is subjected to significant forces that can cause the control units to experience shocks, resulting in relative movement between the control unit and the machine.

[0003] To prevent such relative movements between the control units and the agricultural machinery, the control units are typically mounted to the machinery. Generally, they are bolted or anchored to body components of the agricultural machinery to avoid such movement. A challenge associated with mounting the control units to body components is that this method can lead to excessive vibrations of the control units due to the vehicle's movements. This is especially true when the control units are located on or near a component of the agricultural machinery that causes vibrations, such as a drive motor.When mounting control units, they must be secured in such a way that they cannot come loose and can withstand the vibrations that occur. It is particularly important to note that control units are especially sensitive to vibrations, so a mounting method is necessary that decouples the control unit, at least to a large extent, from these vibrations.

[0004] Therefore, a multi-part mounting system with vibration-damping or -reducing elements is often used for the installation of control units in order to decouple the control unit, at least to a large extent, from the vibrations or oscillations occurring during the operation of the agricultural machinery and also to counteract the influence of shocks on the control units caused by the operation of the agricultural machinery during the execution of work orders.

[0005] For example, US Patent 9,771,030 B1 discloses such a multi-part fastening system for attaching a control unit, in particular an engine control unit, to a vehicle. The fastening system comprises a first fastening element, a second fastening element, and a third fastening element, which is connected to the first and second fastening elements by a plurality of first insulating elements and by a plurality of first fastening means. The third fastening element comprises a base section with a first and a second end. The base section is connected to the control unit by at least one second insulating element and by at least one second fastening means. The third fastening element comprises a first leg that is connected to the first fastening element.The third fastening element further comprises a second leg which is connected to the second fastening element.

[0006] A disadvantage of such well-known multi-part mounting systems for control units in a vehicle is that they comprise a significant number of individual components, all of which must be individually fastened together using a multitude of fasteners. Due to the arrangement of the various fasteners on different levels, it is extremely time-consuming for a technician to install or remove such a mounting system for maintenance purposes, as the fasteners are located on different planes. Furthermore, access to the control unit is limited by the multi-part design of the mounting system or by the vehicle structures surrounding the mounting system, so that the installation of the control unit, and especially its removal for maintenance work, can prove to be very labor-intensive and complex.Accessibility may be further restricted, particularly with agricultural machinery, due to a different vehicle architecture and the presence of specific working units.

[0007] Other fastening systems are known from US 2020 / 047694 A1, CN 110 816 438 B and DE 21 2015 000078 U1.

[0008] Based on this, the object of the present invention is therefore to provide an arrangement for attaching a control unit to the body of an agricultural machine, in particular a tractor, which allows good accessibility to the control unit as well as uncomplicated assembly and disassembly of the control unit on the body of the agricultural machine, while simultaneously achieving sufficient decoupling of the control unit from vibrations and oscillations occurring during the operation of the agricultural machine.

[0009] This problem is solved according to the invention by the features of independent claim 1, wherein advantageous further developments of the arrangement according to the invention are the subject of the corresponding dependent claims 2 to 12.

[0010] The present invention relates to an arrangement for attaching a control unit to the body of an agricultural machine, in particular a tractor. The arrangement comprises a retaining element, which can be attached to or is attached to the body of the agricultural machine, and a support element, on which the control unit can be or is attached. The arrangement is characterized in that the retaining element comprises at least one mounting web. The support element comprises at least one first buffer element and at least one second buffer element, wherein the first buffer element and the second buffer element are arranged on two different sides of the support element. To attach the support element to the retaining element, the first buffer element can be connected to the mounting web and the second buffer element can be connected to the retaining element by means of a fastening device.

[0011] The attachment of the support element to the mounting element via a mounting bracket and the use of a single fastener allows for easy mounting and dismounting of the assembly or control unit from the body of the agricultural machine, requiring access from only one side. By tightening or loosening the fastener, the support element can be easily attached to or removed from the mounting element. The mounting bracket on the mounting element enables secure attachment of the control unit to the body of the agricultural machine using only one fastener.Because the buffer elements are involved in attaching the support element to the mounting element, the control unit is additionally decoupled from any vibrations or oscillations induced by shocks during the movement of the agricultural machinery or by the operation of its implements. At the same time, the number of individual parts is reduced compared to conventional mounting systems, as only two load-bearing elements, the mounting element and the support element, are required to attach the control unit to the body of the agricultural machinery via buffer elements and a combination of a mounting bracket and a fastener.

[0012] The arrangement is particularly suitable for attaching an engine control unit to a body element of the agricultural machinery that serves as a support for the engine hood of the agricultural machinery.

[0013] The arrangement according to the invention is particularly advantageous when attaching an engine control unit to the body element serving as the mounting for the engine hood of the agricultural machinery, since on the one hand, access is very limited due to cables, hoses and various auxiliary units associated with the drive motor, and on the other hand, there is a risk of significant vibrations or oscillations due to the operation of the drive motor.

[0014] According to an advantageous embodiment of the invention, the support element is U-shaped. The support element comprises a first cheek and a second cheek, which are connected to each other by means of a connecting web. The first buffer element is arranged on the first cheek and the second buffer element is arranged on the second cheek.

[0015] The U-shaped design of the support element with two cheeks and a connecting web linking the cheeks ensures a particularly space-saving design of the arrangement, which at the same time creates a connection option for the control unit and allows the integration of buffer elements to reduce or eliminate vibrations.

[0016] Preferably, the first cheek comprises at least one recess, in particular a bore, in which the first buffer element is arranged, and the second cheek comprises at least one recess, in particular a bore, in which the second buffer element is arranged.

[0017] The recesses incorporated into the cheeks provide a particularly simple way to position and attach the buffer elements to the support element. By inserting the buffer elements into the recesses, they can be securely fastened to the support element in such a way that they cannot detach unintentionally. In particular, the arrangement of the buffer elements within the recesses creates a positive-locking connection between the support element and the respective buffer element, thus eliminating the need for additional fasteners and / or adhesives.

[0018] Preferably, the first buffer element and the second buffer element are each arranged in the respective recess of the first cheek and the second cheek such that a recess formed in the first buffer element and a recess formed in the second buffer element for receiving the fastening web or fastening means points away from the connecting web connecting the first cheek and the second cheek.

[0019] This arrangement of the buffer elements allows for good accessibility to the recesses in the buffer elements, enabling the mounting flange or fastener to engage the support element with the retaining element in a particularly straightforward manner. Furthermore, the space between the first and second buffer elements is not used for attaching the support element to the retaining element, so it can be used for connecting or mounting the control unit.

[0020] According to the invention, the retaining element is U-shaped. The retaining element comprises a first cheek and a second cheek, which are connected to each other by means of a connecting web, preferably two connecting webs. The connecting web is formed on the first cheek, and the second cheek comprises at least one recess, in particular a bore, for receiving the fastening element.

[0021] The U-shaped design of the mounting element, with two sides and at least one connecting web linking the two sides, creates a design that is essentially complementary to the support element. This complementary design of the mounting element and support element reduces the installation space required for the assembly, including the control unit.

[0022] According to an advantageous embodiment of the invention, it is provided that the first cheek and the second cheek of the support element and / or the first cheek and the second cheek of the retaining element are arranged on opposite sides of the respective connecting web connecting the two cheeks.

[0023] In principle, this clamps the support element and the retaining element together during assembly by placing the support element between the cheeks of the retaining element, thus ensuring that there is sufficient space for connecting the control unit to the support element and that access to the control unit remains guaranteed even when the control unit is attached to the body of the agricultural machine.

[0024] According to the invention, the mounting bracket is a bolt with a conically shaped bolt head. The first buffer element can be snapped into or is already connected to the mounting bracket.

[0025] During the tightening or loosening of the fastener for mounting or dismounting the carrier element with the retaining element, the locking mechanism ensures that the carrier element, with or without the control unit, does not immediately detach completely from the retaining element and fall off. The mounting or dismounting process can therefore be carried out easily without the risk of accidentally damaging the control unit.

[0026] According to an advantageous embodiment of the invention, it is provided that the second buffer element can be connected to or is connected to the retaining element by means of a screw.

[0027] According to an advantageous embodiment of the invention, it is provided that the first buffer element and / or the second buffer element is designed to dampen vibrations.

[0028] This achieves a particularly high degree of elimination or reduction of vibrations and oscillations, thus protecting the inherently sensitive control unit from potential damage and premature replacement.

[0029] According to an advantageous embodiment of the invention, the first buffer element and / or the second buffer element is designed in a bushing shape.

[0030] This design means that the mounting bracket or fastening element is completely absorbed by the buffer element in the connection area, thus preventing vibrations and oscillations of the fastening element or the mounting bracket from being transmitted to the support element and therefore to the control unit, at least to a large extent.

[0031] According to an advantageous embodiment of the invention, the support element comprises two first buffer elements and two second buffer elements, and the retaining element comprises two fastening webs. To fasten the support element to the retaining element, each first buffer element with a fastening web and each second buffer element can be connected to the retaining element by means of a fastening element.

[0032] This results in a particularly stable connection between the elements. Any twisting of the retaining element and the support element relative to each other due to...

[0033] Vibrations, oscillations and / or shocks can thus be eliminated, thereby preventing unwanted stress states acting on the control unit. According to an advantageous embodiment of the invention, the retaining element is designed to be positively, force-, and / or materially connected to the body of the agricultural machine.

[0034] According to an advantageous embodiment of the invention, the support element can be attached to the control unit by means of force-fit, form-fit, and / or material-fit, or is already attached. Alternatively, the support element is formed integrally with the control unit.

[0035] According to an advantageous further invention, it is provided that the support element comprises cooling fins on a side facing away from the side used for attaching the control unit.

[0036] This gives the support element, in addition to its function of mounting the control unit, the function of dissipating heat generated during the operation of the control unit.

[0037] The problem according to the invention is further solved by an agricultural machine, in particular a tractor, according to claim 13, wherein an advantageous further development of the agricultural machine according to the invention is the subject of the corresponding dependent claim 14.

[0038] Accordingly, the present invention further relates to an agricultural machine, in particular a tractor, with a control unit. The agricultural machine is characterized in that it comprises a previously described arrangement for attaching a control unit to a body of the agricultural machine, by means of which the control unit is attached to the body of the agricultural machine.

[0039] Preferably, the control unit is an engine control unit that is attached by means of the arrangement to a body element of the agricultural machinery serving as a support for the engine hood of the agricultural machinery. The present invention is described in more detail below with reference to the embodiments illustrated in the figures.

The agricultural machine 1 trained as a tractor 2 includes, among other things, a body 3, soil infiltration devices 4, a cabin 5 mounted on the body 3, and - in FIG. 1 Not shown - working units.

[0042] In addition to these components, the tractor 2 also includes at least one control unit 6, which is used to process data for controlling the tractor 2's working units. FIG. 2 One such control unit 6 is shown, which is attached to the body 3 of the tractor 2. In the case of the FIG. 2 The control unit 6 shown is an engine control unit, which serves to control a drive motor 7 of the tractor 2. The engine control unit is mounted on one of the brackets of a - in FIG. 1 The depicted engine hood 8 of the tractor 2 is attached to the body element 9.

[0043] Referring to the FIGs. 3 bis 5 An embodiment according to the invention of such an arrangement 10 for attaching a control unit 6 to the body 3 of an agricultural work machine 1, here and preferably a tractor 2, is described below.

[0044] Although the arrangement 10 according to the invention is described below in the context of an agricultural machine 1 designed as a tractor 2, the arrangement 10 can equally be used in the context of other agricultural machines 1, such as a combine harvester or a forage harvester. The same applies to the design of the control unit 6. Even though the control unit described in the FIGs. 2 bis 4 Since the control unit 6 shown is an engine control unit, the arrangement 10 is not only suitable for mounting engine control units, but equally suitable for mounting other control units of an agricultural machine 1 or a tractor 2. Furthermore, the tractor 2 can comprise not just one control unit 6, but a plurality of control units 6, which serve to control various working units of the tractor 2, each of the plurality of control units 6 being attachable or mounted on the body 3 of the tractor 2 by means of an arrangement 10 according to the invention.

[0045] FIG. 3 Figure 1 shows an embodiment of the arrangement 10 according to the invention. The arrangement 10 comprises a retaining element 11, which can be attached to or is attached to the body 3 of the tractor 2. The attachment of the retaining element 11 to the body 3 of the tractor 3 can optionally be by positive locking, force locking, and / or material locking. Preferably, the retaining element 11 is screwed to the body 3 of the tractor 2. In addition to the retaining element 11, the arrangement 10 further comprises a support element 12, on which the control unit 6 can be arranged or is arranged. The connection of the control unit 6 to the support element 12 can optionally be by force locking, positive locking, and / or material locking. Preferably, the control unit 6 is screwed to the support element 12, here and preferably, as shown in Figure 1. FIG. 4 As shown, a screw-nut combination is used for fastening. Alternatively, the support element 12 can also form a component of the control unit 6. In other words, the support element 12 and the control unit 6 are integrally formed in this configuration. The retaining element 11 comprises two mounting lugs 13, and the support element 12 comprises two first buffer elements 14 and two second buffer elements 15. Although the FIGS. show two mounting lugs 13 and two first buffer elements 14 and two second buffer elements 15, an embodiment of the arrangement 10 according to the invention with only one mounting lug 13 and with only one first buffer element 14 and one second buffer element 15 is equally possible.

[0046] The first buffer elements 14 and the second buffer elements 15 are arranged on two different sides of the support element 12. In the embodiment shown in the FIGS., with two mounting webs 13, two first buffer elements 14 and two second buffer elements 15, the two mounting webs 13 are arranged on the same side of the support element 12.

[0047] To attach the support element 12 to the retaining element 11, a first buffer element 14 can be connected to a corresponding mounting web 13 of the retaining element 11, and a second buffer element 15 can be connected directly to the retaining element 11 by means of a fastening element 16. Therefore, when the retaining element 11 is mounted to the support element 12, or when the assembly 10 is mounted on the tractor 2, a first buffer element 14 is connected to a corresponding mounting web 13 of the retaining element 11, and a second buffer element 15 is connected directly to the retaining element 11 by means of a fastening element 16.

[0048] The support element 12 of the arrangement 10 is U-shaped. The support element 12 comprises a first cheek 17 and a second cheek 18, which are connected to each other by means of a connecting web 19. The connecting web 19 serves to attach or connect the control unit 6. The first buffer elements 14 are arranged on the first cheek 17 and the second buffer elements 15 on the second cheek 18. For this purpose, the first cheek 17 comprises two recesses, which are designed in particular as bores, with a first buffer element 14 arranged in each recess. The second cheek 18 correspondingly comprises two recesses, which are also designed in particular as bores, with a second buffer element 15 arranged in each recess.The first buffer elements 14 and the second buffer elements 15 are arranged in their respective recesses in one of the cheeks 17, 18 such that a recess 20 formed in each first buffer element 14 and each second buffer element 15, which is particularly in . FIG. 4 shown, is oriented to receive a fastening web 13 or a fastening means 16 such that it points away from the connecting web 19 which connects the first and second cheek 17, 18 of the support element 12.

[0049] The first buffer elements 14 and the second buffer elements 15 are preferably designed in a bushing shape, so that either the fastening web 13 or the fastening means 16 engages in the bushing-shaped buffer elements 14, 15 when the retaining element 11 is fastened to the support element 12, thereby being completely received or surrounded by the respective buffer element 14, 15 in the connection area.

[0050] Preferably, the first and second buffer elements 14, 15 are designed to dampen vibrations, so that vibrations acting on the retaining element 11 are prevented from being transmitted to the support element 12 and thus to the control unit 6. In other words, the buffer elements 14, 15 reduce or eliminate any vibrations that may occur and thus protect the control unit 6 during operation of the tractor 2. The first and second buffer elements 14, 15 are particularly preferably made of an elastomeric plastic.

[0051] The fastening webs 13 are, as shown in the isolated partial representation of the retaining element 11 according to FIG. 5 The first buffer elements 14 and the fastening webs 13, which engage with each other when the retaining element 11 is fastened to the support element 12, form a snap-fit ​​connection with the fastening web 13 in this configuration, which provides a certain degree of security against unintentional detachment of the support element 12 from the retaining element 11 during an assembly or disassembly process of the arrangement 10.

[0052] Furthermore, it is preferably provided that the fastening means 16 are each designed as a screw, so that the second buffer element 15 can be connected to the retaining element 11 via a screw connection. However, other configurations of the fastening means 16 are equally possible.

[0053] Corresponding to the support element 12, the retaining element 11 of the arrangement 10 is also U-shaped, so that the support element 12 and the retaining element 11 are at least substantially complementary. Accordingly, the retaining element 11 also comprises a first cheek 21 and a second cheek 22, which are connected to each other by means of two connecting webs 23. Instead of two connecting webs 23, a connection of the cheeks 21 and 22 via only one connecting web 23 is also possible. The fastening webs 13 are formed on the first cheek 21. The second cheek 22 comprises two recesses 24, which are located in FIG. 4 shown, which are designed in particular as bores and serve to accommodate the fastening means 16.

[0054] In both the retaining element 11 and the support element 12, it is provided that the first cheek 17, 21 and the second cheek 18, 22 are arranged on opposite sides of the connecting web 19, 23 connecting the two cheeks 17, 18; 21, 22.

[0055] In a mounted state of the retaining element 11 on the body 3 of the tractor 2, both the first cheek 21 and the second cheek 22 of the retaining element 11 point away from the body 3 of the tractor 2. The support element 12, on the other hand, can optionally be oriented in a state attached to the retaining element 11 such that the first and second cheeks 17, 18 of the support element 12 point away from the retaining element 11, as shown in FIG. 3 shown, or point in the direction of the retaining element 11, as shown in FIG. 4 depicted.

[0056] The support element 12 can, as the FIG. 4As can be seen, in addition to the mounting function for the control unit 6, an optional further function can be provided. Cooling fins 25 can be formed on a side facing away from the side on which the control unit 6 is located. The heat generated during operation of the control unit 6 can be efficiently dissipated via the cooling fins 25 of the support element 12.

[0057] Finally, it should be noted that the embodiments described above serve only to describe the claimed teaching, but are by no means to be regarded as limiting or exhaustive. Reference symbol list
