Description

Technical Field

[0001] This invention relates to the field of engine testing technology, and more specifically to a mounting bracket for the transmission mounting end face of an automobile engine. Background Technology

[0002] Before leaving the factory, engines typically undergo bench testing, and only those that pass the test can be put into use. Bench testing mainly involves mounting the engine on a bench and, by setting up a suitable bench, ensuring that the engine's posture is as consistent as possible with its posture when mounted on the vehicle body, thereby guaranteeing the accuracy of the simulated operating data.

[0003] In existing technology, the test bench includes multiple support columns. When fixing the engine to the support columns, since some areas of the engine lack support points, a tooling bracket is first fixed to the engine with bolts, and then the tooling bracket is fixedly connected to the support columns to achieve the fixation of the engine by the support columns. For example, the installation mechanism described in the Chinese patent [Publication No.: CN115326405B] for an engine testing lifting bracket.

[0004] However, due to the different bolt hole positions on the transmission mounting face of different engine models, different engines require the production of matching tooling brackets, making it difficult to achieve the universality of tooling brackets. Furthermore, the time spent on custom tooling brackets is relatively long, which seriously reduces work efficiency. Summary of the Invention

[0005] One of the objectives of this invention is to provide a mounting bracket for the transmission mounting end face of an automobile engine, in order to solve the problem in the prior art that different engines require the production of matching tooling brackets, making it difficult to achieve the universality of tooling brackets.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A mounting bracket for an automotive engine and transmission is provided. The mounting bracket is installed on multiple threaded holes on the mounting surface of the engine and transmission for connection to a support column of a test bench. The bracket assembly includes a mounting base and a support arm. The mounting base is provided with a first mounting point, a second mounting point, and a third mounting point. The mounting base is connected to the mounting surface of the engine and transmission via the first mounting point. One end of the support arm is connected to the mounting surface of the engine and transmission, and the other end is rotatably connected to the second mounting point. The mounting base is fixedly connected to the support column via the third mounting point.

[0008] Furthermore, the support arm includes a first connector, a second connector, and an adjusting cylinder. The first connector and the second connector are respectively connected to the two ends of the adjusting cylinder. The positions of the first connector and the second connector can be adjusted along the axial direction of the adjusting cylinder. The free end of the first connector is rotatably connected to the second mounting point, and the free end of the second connector is connected to the engine and transmission mounting end face.

[0009] Furthermore, both ends of the adjusting cylinder are provided with internal threads, and the first connector and the second connector are respectively threaded to the two ends of the adjusting cylinder.

[0010] Furthermore, the mounting base is provided with a connecting lug, the second mounting point is a second mounting hole, the second mounting hole is opened on the connecting lug, the first connecting head is provided with a connecting groove, the connecting lug is inserted into the connecting groove, the first connecting head is provided with a first bolt, the first bolt passes through the first connecting head and the second mounting hole, and a first nut for locking the first connecting head and the connecting lug is screwed onto the first bolt.

[0011] Furthermore, the second connector is provided with a second double-ended stud, one end of which passes through the second connector and the other end is threadedly connected to the threaded hole on the engine and transmission mounting face. A second nut for locking the second double-ended stud and the second connector is screwed onto the second double-ended stud.

[0012] Furthermore, one end of the mounting base is provided with a mounting post, the first mounting point is a first mounting hole, the first mounting hole is opened on the mounting post, a first double-ended stud is inserted into the first mounting hole, one end of the first double-ended stud is threadedly connected to the threaded hole on the mounting end face of the engine and transmission, and the other end passes through the mounting post, and a third nut for locking the mounting post and the first double-ended stud is screwed onto the first double-ended stud.

[0013] Furthermore, two support arms are provided, which are respectively connected to the upper and lower sides of the mounting base, and form a triangular fixing area between the two support arms and the mounting base.

[0014] Furthermore, the bracket assembly is provided in two sets, and the mounting bases of the two sets of bracket assemblies are located on the same plane.

[0015] The beneficial effects of this invention are:

[0016] 1. The present invention improves the versatility of the fixed bracket by setting a mounting base and a support arm, the position of which is adjustable, so that the support arm can be connected to threaded holes in different positions.

[0017] 2. By configuring the support arm as a first connector, a second connector, and an adjusting cylinder, the length of the support arm can be adjusted by rotating the adjusting cylinder, so that the support arm can connect to threaded holes at different positions within a wider range, further improving the versatility of the fixed bracket.

[0018] 3. By setting a first double-ended stud and a second double-ended stud, when the size of the bolt hole on the gearbox mounting end face also changes, only the model of the first double-ended stud and the second double-ended stud needs to be changed.

[0019] 4. This invention improves the support strength of the fixed bracket by setting support arms on both sides of the mounting base, so that the two support arms and the mounting base form a triangular fixing area.

[0020] 5. By setting two sets of bracket assemblies, the present invention can further improve the stability of the fixed bracket, and by changing the tilt angle of the two mounting seats, the tilt state of the engine can be adjusted so that the engine posture is as consistent as possible with the posture when it is installed on the vehicle body, thereby ensuring the accuracy of the simulated operation data.

[0025] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0026] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0027] like Figures 1-3 As shown, this embodiment proposes a mounting bracket for an automotive engine and transmission. The bracket is installed on the engine and transmission mounting surface 1, which has multiple threaded holes 11. The bracket includes two sets of bracket assemblies, which effectively improve the stability of the bracket. Each bracket assembly includes a mounting base 2 and two support arms 3 located on both sides of the mounting base 2. The two support arms 3 and the mounting base 2 form a triangular fixing area, effectively improving the support strength of the bracket.

[0028] In this embodiment, the mounting base 2 is provided with a first mounting point, a second mounting point, and a third mounting point. Specifically,

[0029] One end of the mounting base 2 is provided with a mounting post 21, and the first mounting point is a first mounting hole 211. The first mounting hole 211 is formed on the mounting post 21, and a first double-ended stud 4 is inserted into the first mounting hole 211. One end of the first double-ended stud 4 is threaded to the threaded hole 11 on the transmission mounting end face, and the other end passes through the mounting post 21. A third nut 41 for locking the mounting post 21 and the first double-ended stud 4 is screwed onto the first double-ended stud 4, thereby achieving a fixed connection between the mounting base 2 and the engine transmission mounting end face 1. Furthermore, by providing the first double-ended stud 4, changing the model of the first double-ended stud 4 can adapt to threaded holes 11 of different diameters.

[0030] The mounting base 2 is provided with a connecting ear 22, and the second mounting point is a second mounting hole 221. The second mounting hole 221 is formed on the connecting ear 22. One end of the support arm 3 is connected to the connecting ear 22, and the other end is connected to the threaded hole 11 in the engine and transmission mounting end face 1, thereby connecting the mounting base 2 and the support arm 3. Moreover, the position between the support arm 3 and the mounting base 2 is adjustable, so that the support arm 3 can be connected to the threaded hole 11 in different positions, improving the versatility of the fixing bracket.

[0031] Mounting bracket 2 is fixedly connected to the support column via a third mounting point, thus achieving a fixed connection between the engine and the support column via a fixed bracket. This embodiment does not impose specific limitations on the structure of the third mounting point; conventional techniques from the prior art, such as bolted connections or clamped connections, are sufficient. It should be noted that the mounting brackets 2 of the two bracket assemblies are located on the same plane. During installation, by changing the tilt angle of the two mounting brackets 2, the tilt state of the engine can be adjusted, ensuring that the engine's posture is as consistent as possible with its posture when installed on the vehicle body, thereby guaranteeing the accuracy of the simulated operating data.

[0032] In this embodiment, the support arm 3 includes a first connector 31, a second connector 32, and an adjusting cylinder 33. Both ends of the adjusting cylinder 33 are provided with internal threads. The first connector 31 and the second connector 32 are respectively threaded to both ends of the adjusting cylinder 33. By rotating the adjusting cylinder 33, the length of the support arm 3 can be adjusted, allowing the support arm 3 to connect to threaded holes 11 at different positions within a wider range, further improving the versatility of the fixing bracket. It should be noted that the adjusting cylinder 33 in this embodiment is provided with hexagonal protrusions. When it is necessary to rotate the adjusting cylinder 33, the hexagonal protrusions can be turned with a wrench to achieve the purpose of rotating the adjusting cylinder 33.

[0033] In this embodiment, the first connector 31 has a connecting groove 311, and the connecting lug 22 is inserted into the connecting groove 311. The first connector 31 is provided with a first bolt 61, which passes through the first connector 31 and the second mounting hole 221. A first nut for locking the first connector and the connecting lug is screwed onto the first bolt. Tightening the first nut 62 can fix the mounting base 2 to the support arm 3, and loosening the first nut 62 can adjust the position of the support arm 3 to adapt to the threaded hole 11 in different positions.

[0034] In this embodiment, a second double-ended stud 5 is provided on the second connector 32. One end of the second double-ended stud 5 passes through the second connector 32 and is connected to a second nut 51, while the other end is threadedly connected to the threaded hole 11 on the engine and transmission mounting face 1. A second nut 51 for locking the second double-ended stud 5 and the second connector 32 is screwed onto the second double-ended stud 5. The connection between the support arm 3 and the engine and transmission mounting face 1 is achieved through the second double-ended stud 5, and different diameter threaded holes 11 can be adapted by changing the model of the second double-ended stud 5.

[0035] The method of using this invention is as follows:

[0036] First, select the appropriate first double-ended stud 4 and second double-ended stud 5 according to the engine model, and thread one end of the first double-ended stud 4 and one end of the second double-ended stud 5 into the appropriate threaded hole 11 on the engine and transmission mounting face 1 respectively.

[0037] Subsequently, the mounting base 2 is installed on the first double-ended stud 4 via the mounting post 21 and the third nut 41, and the tilt angle of the mounting base 2 is adjusted as needed during installation. The mounting base 2 of the other bracket assembly is then secured using the same method.

[0038] Then, the second connector 32 of the support arm 3 is put onto the second double-ended stud 5, and the adjusting cylinder 33 is rotated to change the length of the support arm 3 until the first connector 31 of the support arm 3 is engaged with the mounting ear and the first bolt 61 can be inserted into the second mounting hole 221.

[0039] Finally, the first connector 31 is fixed to the mounting base 2 by the first nut 62, and the remaining three support arms 3 are fixed in the same way.

[0040] The above embodiments are merely preferred embodiments provided to fully illustrate the present invention, and the scope of protection of the present invention is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present invention are all within the scope of protection of the present invention.
