Description

Technical Field

[0001] The utility model relates to the technical field of engines, and in particular to an engine support component, an engine system and a vehicle. Background Art

[0002] The engine bracket is a device used to fix and support the engine body, and is used to bear the weight of the engine body as well as various loads and moments applied to the engine body; the engine bracket generally includes a rigid bracket, an elastic bracket, and a hybrid structure bracket.

[0003] As for the rigid bracket, it has good bearing capacity and anti-vibration performance, and is usually suitable for vehicles with harsh working environments such as tractors. The rigid bracket is usually installed on the engine body and the oil pan at the same time. Due to the height difference between the rigid bracket body mounting surface and the rigid bracket oil pan mounting surface, and the processing errors of each structure, after the rigid bracket is tightened relative to the engine body by bolts, it will generate assembly stress without external force, thus affecting the overall strength of the rigid bracket.

[0004] Therefore, how to design an engine rigid bracket that can reduce the assembly stress generated during assembly while ensuring the load-bearing capacity and seismic resistance has become a technical problem that needs to be solved urgently in this field. Utility Model Content

[0032] Figure 1 A schematic diagram of the structure of the engine support assembly provided by an embodiment of the utility model at a viewing angle; Figure 2 A schematic diagram of the structure of the engine support assembly provided by the embodiment of the utility model from another perspective; Figure 1 and Figure 2 As shown, an embodiment of the utility model provides an engine support assembly 100 for fixing and supporting a body of an engine, the engine support assembly 100 comprising: a bracket (not shown in the figure); a rigid bracket 1 having a first mounting surface 11, the first mounting surface 11 being detachably connected to the bracket; a connecting mechanism for detachably connecting the rigid bracket 1 to the body; and an oil pan 2, spaced apart from the rigid bracket 1 along a first direction, the oil pan 2 having a second mounting surface 21, the second mounting surface 21 being detachably connected to the bracket, and the second mounting surface 21 and the first mounting surface 11 being in the same plane.

[0033] In this embodiment, when the engine support assembly 100 is assembled, the engine support assembly 100 is first adjusted to the assembly station, that is, the second mounting surface 21 and the first mounting surface 11 are in the same plane, and then the first mounting surface 11 is connected to the bracket, and the second mounting surface 21 is connected to the bracket, and the assembly of the engine support assembly 100 is completed. Finally, the body is connected to the rigid bracket 1 through the connecting mechanism, and the assembly of the engine support assembly 100 and the body is completed.

[0034] That is to say, there is no direct connection between the rigid bracket 1 and the oil pan 2 , and no assembly stress will be generated during assembly due to a height difference between the oil pan 2 mounting surface of the rigid bracket 1 and the engine body mounting surface.

[0035] Therefore, the engine support assembly 100 can reduce the assembly stress generated during assembly; in addition, since the bracket in the engine support assembly 100 is still the rigid bracket 1, the overall load-bearing capacity and anti-seismic performance of the engine support assembly 100 can also be guaranteed.

[0036] refer to Figure 1 According to an optional embodiment of the present application, the engine support assembly 100 further includes a limiting mechanism 3, which is used to limit the relative displacement between the rigid support 1 and the oil pan 2 along a second direction, and the second direction is perpendicular to the first direction.

[0037] In this embodiment, when assembling the engine support assembly 100, due to the presence of the limiting mechanism 3, the relative displacement between the rigid bracket 1 and the oil pan 2 along the second direction can be limited, that is, the limiting mechanism 3 can conveniently ensure that when the engine support assembly 100 is connected to the vehicle bracket, the second mounting surface 21 and the first mounting surface 11 are in the same plane.

[0038] It is easy to understand that if the engine support assembly 100 is not provided with a limiting mechanism 3, then when assembling the engine support assembly 100, it is necessary to use an external leveling device (such as a flat plate) to ensure that the second mounting surface 21 and the first mounting surface 11 are in the same plane to ensure that the engine support assembly 100 can be in the assembly position, and then the leveling device needs to be disassembled and removed, which is cumbersome.

[0039] Therefore, the provision of the limiting mechanism 3 can improve the assembly efficiency of the engine support assembly 100.

[0040] Among them, along the first direction, a card slot can be set at one end of the oil pan 2 close to the rigid bracket 1, and a card block that is engaged with the card slot is set at one end of the rigid bracket 1 close to the oil pan 2, and the card block and the card slot constitute a limiting mechanism 3. The position of the card slot is set to meet: when the card block is inserted into the card slot, the second mounting surface 21 and the first mounting surface 11 are in the same plane. In this way, when assembling, the card block is inserted into the card slot to adjust the engine support assembly 100 to the assembly position.

[0041] Continue to refer Figure 1 According to an optional embodiment of the present application, along the first direction, a first boss 12 is provided at one end of the rigid bracket 1 close to the oil pan 2, and a second boss 22 is provided at one end of the oil pan 2 close to the rigid bracket 1. The first boss 12 and the second boss 22 are arranged along the second direction, the first boss 12 abuts against the boss, and the first boss 12 and the second boss 22 constitute a limiting mechanism 3.

[0042] In this embodiment, when assembling the engine support assembly 100, the engine support assembly 100 is first adjusted to the assembly position, that is, the first mounting surface 11 and the second mounting surface 21 are in the same plane; Figure 1 , when the engine support assembly 100 is in the assembly station, the first boss is located on the side of the second boss away from the first mounting surface 11 in the first direction as an example for explanation:

[0043] When the engine support assembly 100 is in the assembly station, due to the presence of the first boss 21 and the second boss 22, the rigid bracket 1 cannot move in the first direction toward the side close to the first mounting surface 11, and the oil pan 2 cannot move in the first direction toward the side away from the second mounting surface 21, thereby achieving the positioning of the rigid bracket 1 and the oil pan 2 in the second direction.

[0044] Therefore, the first boss 12 and the second boss 22 can conveniently place the engine support assembly 100 in the assembly position, thereby improving the assembly efficiency of the engine support assembly 100.

[0045] It should be noted that this embodiment is only based on Figure 1 Take the case as an example, under actual working conditions, the second boss in the second direction may be located on the side of the first boss away from the second mounting surface 21, and the positions of the first boss 12 and the second boss 22 in the second direction are not limited, and are subject to actual needs, as long as the first mounting surface 21 and the second mounting surface 22 can be in the same plane.

[0046] like Figure 1 and Figure 2 As shown, according to an optional embodiment of the present application, the connecting mechanism includes a bolt 4 .

[0047] In this embodiment, the bolt 4 connection method has a simple structure and is simple and convenient to operate. While ensuring the reliability of the connection between the rigid bracket 1 and the body, it can also improve the efficiency of assembly and disassembly.

[0048] Among them, there can be multiple bolts 4, and multiple bolts 4 are arranged at intervals to improve the stability of the connection; in addition, the bolts 4 can be selected as hexagonal flange bolts 4, which have good steel plasticity, high strength, strong torque resistance and shear resistance, and can further ensure the reliability of the connection.

[0049] refer to Figure 1 and Figure 2 According to an optional embodiment of the present application, the first mounting surface 11 is provided with a first mounting hole 111 for mounting the bracket, and the second mounting surface 21 is provided with a second mounting hole 211 for mounting the bracket.

[0050] In this embodiment, the bracket can be connected to the first mounting hole 111 on the first mounting surface 11 through a connecting rod to achieve the connection between the bracket and the rigid support 1; similarly, the bracket can also be connected to the second mounting hole 211 on the second mounting surface 21 through a connecting rod to achieve the connection between the bracket and the oil pan 2.

[0051] The first mounting hole 111 and the second mounting hole 211 can both be threaded holes, and the connecting rod is a screw rod, and the rigid support 1 and the oil pan 2 are respectively connected to the bracket by threaded connection.

[0052] In addition, to ensure the connection stability, the first mounting hole 111 and the second mounting hole 211 can be provided in plurality, such as Figure 1 and Figure 2 As shown, a plurality of second mounting holes 211 are provided.

[0053] Continue to refer Figure 1 and Figure 2 According to an optional embodiment of the present application, the first mounting hole 111 and the second mounting hole 211 are arranged at intervals along the first direction.

[0054] In this embodiment, the first mounting hole 111 and the second mounting hole 211 are located on the same straight line in the same plane, so that the rigid bracket 1 and the oil pan 2 can be subjected to uniform force.

[0055] like Figure 1 and Figure 2 As shown, according to an optional embodiment of the present application, there are two rigid brackets 1, and the two rigid brackets 1 are arranged at intervals along a third direction, the third direction is perpendicular to the first direction, and the third direction is perpendicular to the second direction; along the third direction, an accommodating space 5 for installing the body is formed between the two rigid brackets 1.

[0056] In this embodiment, the connection method and beneficial effects of any one of the two rigid brackets 1 are the same as those described above, and will not be described again.

[0057] It should be noted that in this embodiment, two rigid brackets 1 are arranged at intervals along the third direction, and the body is placed in the accommodating space 5 during assembly. In this way, when the two rigid brackets 1 are respectively connected to the two sides of the body, the force on the body can be evenly distributed, and the reliability of the connection between the engine support assembly 100 and the body is further improved.

[0058] refer to Figure 1 and Figure 2According to an optional embodiment of the present application, the oil pan 2 has two second mounting surfaces 21, the two second mounting surfaces 21 are arranged at intervals along the third direction, and the two second mounting surfaces 21 are arranged one-to-one with the two first mounting surfaces 11; when the engine support assembly 100 is in the assembly station, in a group of corresponding first mounting surfaces 11 and second mounting surfaces 21, the first mounting surfaces 11 and the second mounting surfaces 21 are in the same plane.

[0059] In this embodiment, similarly, the positional relationship between each first mounting surface 11 and the corresponding second mounting surface 21 is the same as described above and will not be described in detail.

[0060] It should be noted that when the engine support assembly 100 is in the assembly station, the two first mounting surfaces 11 can also be in the same plane, and the two second mounting surfaces 21 can also be in the same plane; that is, the two first mounting surfaces 11 and the two second mounting surfaces 21 are all in the same plane. In this way, when the engine support assembly 100 is connected to the bracket, the connection position of the engine support assembly 100 and the bracket is relatively more stable, which further ensures the connection reliability and improves the convenience of assembly to a certain extent.

[0061] The embodiment of the utility model further provides an engine system, which includes an engine body and any one of the above-mentioned engine support assemblies 100 , wherein the engine body is detachably connected to the rigid bracket 1 of the engine support assembly 100 via a connecting mechanism.

[0062] In this embodiment, the beneficial effects of the engine system are the same as those of any of the above-mentioned engine support assemblies 100 , which are to reduce the assembly stress generated during assembly while ensuring the bearing capacity and anti-seismic performance, and the details will not be repeated.

[0063] An embodiment of the utility model further provides a vehicle, which includes a vehicle body and the above-mentioned engine system, and a bracket is fixedly connected to the vehicle body.

[0064] In this embodiment, the beneficial effects of the vehicle are the same as the beneficial effects of the above-mentioned engine system and will not be described in detail.

[0065] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model.
