[0002] An active hydraulic suspension system is an advanced suspension system based on hydraulic technology. It can adjust suspension performance parameters (such as stiffness, damping, and vehicle height) in real time according to road conditions, driving states, and driver needs to improve driving comfort, enhance vehicle handling and stability, and enable the vehicle to adapt to different driving conditions. The suspension hydraulic pump is one of the core components of the active hydraulic suspension system. Its main purpose is to provide high-pressure hydraulic oil to the system, driving hydraulic actuators (such as hydraulic cylinders) to achieve dynamic adjustment of the suspension.

[0003] Currently, vehicle suspension hydraulic pumps are generally bolted to the subframe, creating a rigid connection. However, these pumps generate vibration and noise during operation, which can be transmitted to other parts of the vehicle, affecting driving stability and passenger comfort. This vibration and noise are particularly pronounced when driving on bumpy roads, and may even damage the suspension hydraulic pump. Utility Model Content

[0025] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0026] Please see Figures 1 to 4It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the disclosed technical content. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0027] To provide a detailed description of this utility model, the following will specifically describe a powertrain and vehicle integrating a suspension hydraulic pump. It should be noted that in this application, the position of the crankcase 302 is considered "upper," the position of the oil pan 301 is considered "lower," and the height direction of the crankcase 302 is the direction from top to bottom of the powertrain body 3.

[0028] Please combine Figures 1 to 4 As shown, this utility model provides a powertrain integrating a suspension hydraulic pump, including a powertrain main body 3, a suspension system, and a suspension hydraulic assembly 1. The powertrain main body 3 has a suspension placement position and a suspension hydraulic pump mounting position, with the suspension hydraulic pump mounting position located outside the suspension placement position, meaning there is no overlapping area between the suspension hydraulic pump mounting position and the suspension placement position. The suspension system is disposed on the suspension placement position. The suspension hydraulic assembly 1 includes a suspension hydraulic pump and is disposed on the suspension hydraulic pump mounting position. By integrating the suspension hydraulic assembly 1 with the powertrain main body 3, the suspension system of the powertrain can effectively absorb the vibration generated when the suspension hydraulic assembly 1 is working, preventing the vibration from being transmitted to the vehicle body and affecting the overall driving experience. It can also prevent the vibration from generating noise, thereby improving the overall driving comfort of the vehicle. The suspension hydraulic assembly 1 is mounted on the powertrain main body 3, which can make full use of the space in the powertrain compartment. The suspension hydraulic assembly 1 does not require a separate suspension system, which reduces the overall vehicle weight, vehicle manufacturing cost, and the interior space required for the aforementioned suspension system layout, and also makes the overall vehicle layout more compact.

[0029] In this embodiment, the powertrain unit 3 is a reciprocating internal combustion engine. In some embodiments, the powertrain unit 3 may also be a rotary engine or an electric motor. The placement of the suspension hydraulic pump on different types of powertrain units 3 can be adjusted according to the actual structure of the powertrain unit 3.

[0030] The powertrain unit 3 includes a crankcase 302 and an oil pan 301, which are connected. The suspension hydraulic pump mounting position is at least partially located on the crankcase 302. In this embodiment, the powertrain unit 3 is an engine. Since the crankcase 302 of the engine needs to house key components such as the crankshaft, the crankshaft is subjected to enormous torque, bending moment, and other forces during engine operation. For example, when the crankshaft in a car engine rotates at high speed, a large pressure is generated between the connecting rod journal and the connecting rod big end bearing. These forces are transmitted to the crankcase wall. If the crankcase 302 is not strong enough, it may deform, thereby affecting the normal operation of the crankshaft, or even causing collision damage between the crankshaft and the crankcase 302. Therefore, the crankcase 302 in an engine generally has high strength. By mounting the suspension hydraulic assembly 1 on the crankcase 302, its high strength can be utilized to improve the stability of the suspension hydraulic assembly 1 mounted on the powertrain unit 3.

[0031] Specifically, the crankcase 302 has an air conditioning compressor mounting position, and the suspension hydraulic pump mounting position is at least partially located above the suspension hydraulic pump mounting position. The air conditioning compressor 2 is installed on the air conditioning compressor mounting position. By arranging the suspension hydraulic assembly 1 between the air conditioning compressor 2 and the oil pan 301, the space in the powertrain compartment can be rationally utilized, making the layout in the powertrain compartment more compact and improving the utilization rate of the powertrain compartment space.

[0032] like Figure 3 and Figure 4 As shown, the suspension hydraulic assembly 1 has a first connecting lug 4 and a second connecting lug 5 on the side near the air conditioning compressor mounting position. The suspension hydraulic assembly 1 is connected to the crankcase 302 through the first connecting lug 4 and the second connecting lug 5. The air conditioning compressor mounting position is at least partially sandwiched between the first connecting lug 4 and the second connecting lug 5. This facilitates the installation of the suspension hydraulic assembly 1 on the crankcase 302 and also reduces the distance between the air conditioning compressor 2 and the suspension hydraulic assembly 1, so as to reduce the installation space occupied by the suspension hydraulic assembly 1 and the air conditioning compressor 2 while ensuring a reasonable interval between them.

[0033] The crankcase 302 has a first connecting flange 3023 for connecting to the oil pan 301. The suspension hydraulic assembly 1 has a third connecting lug 6 corresponding to the first connecting flange 3023, and the suspension hydraulic assembly 1 is connected to the crankcase 302 via the third connecting lug 6. The connection between the suspension hydraulic assembly 1 and the first connecting flange 3023 of the crankcase 302 ensures the stability of the suspension hydraulic assembly 1 mounted on the powertrain 3, while eliminating the need to increase the height of the crankcase 302 to match the suspension hydraulic assembly 1, thus saving on engine manufacturing material costs. Simultaneously, the first connecting flange 3023 of the crankcase 302 can distribute the weight of the suspension hydraulic assembly 1 along the height direction of the crankcase 302. In this embodiment, the suspension hydraulic assembly 1 is provided with two third connecting ears 6, which are respectively provided for the first connecting ear 4 and the second connecting ear 5. The first connecting ear 4, the second connecting ear 5 and the two third connecting ears 6 are respectively connected to the crankcase 302, so that the suspension hydraulic assembly 1 can be better fixed on the powertrain body 3.

[0034] In this embodiment, the suspension hydraulic assembly 1 includes two suspension hydraulic pumps, each corresponding to the suspension system of each front wheel of the vehicle. In some embodiments, the suspension hydraulic assembly 1 includes four suspension hydraulic pumps, each corresponding to the suspension system of each wheel of the vehicle.

[0035] Specifically, the oil pan 301 is bolted to the crankcase 302, and the suspension hydraulic assembly 1 is bolted to the crankcase 302. The oil pan 301 has a second connecting flange 3012 corresponding to the first connecting flange 3023. The bolt passes through the third connecting lug 6 and the second connecting flange 3012 before connecting to the first connecting flange 3023. This arrangement strengthens the tightness of the connection between the first threaded connecting flange 3023 and the second connecting flange 3012 without increasing the flange width of the first connecting flange 3023. In this embodiment, the bolt passes through the third connecting lug 6 and the second connecting flange 3012 before threadedly connecting to the first connecting flange 3023. The suspension hydraulic assembly 1 is bolted to the powertrain body 3, facilitating the installation and removal of the suspension hydraulic assembly 1 during maintenance and replacement. In some embodiments, the bolt passes through the third connecting lug 6 and the second connecting flange 3012 before connecting to the first connecting flange 3023 via a nut. The connection method between the suspension hydraulic assembly 1 and the crankcase 302 can be adjusted according to actual usage needs.

[0036] In detail, the first connecting flange 3023 has a first abutting surface and a first back surface disposed opposite to each other. The first abutting surface is used to abut against the second connecting flange 3012. A first connecting protrusion 3022 is provided on the first back surface corresponding to the third connecting lug 6. In this embodiment, the bolt passes through the third connecting lug 6 and the second connecting flange 3012 and is threadedly connected to the first connecting flange 3023 and the first connecting protrusion 3022. By providing the first connecting protrusion 3022, the area of ​​threaded connection between the bolt at the third connecting lug 6 and the first connecting flange 3023 can be increased, thereby improving the stability of the connection between the bolt at the third connecting lug 6 and the first connecting flange 3023. In this embodiment, a second connecting protrusion 3011 is provided on the side of the second connecting flange 3012 away from the first connecting flange 3023. This second connecting protrusion 3011 corresponds to the first connecting protrusion 3022. A through hole is provided on the second connecting protrusion 3011 for inserting a bolt. This through hole corresponds to the threaded hole on the first connecting flange 3023. In this embodiment, the third connecting lug 6 is provided on the side of the suspension hydraulic assembly 1 away from the air conditioning compressor 2. By providing the second connecting protrusion 3011, the gap between the third connecting lug 6 and the second connecting flange 3012 can be filled, so that the first connecting flange 3023 and the second connecting flange 3012 are tightly attached, thereby improving the tightness of the connection between the oil pan 301 and the crankcase 302.

[0037] In some embodiments, the bolt passes through the third connecting lug 6 and the second connecting flange 3012 and is threadedly connected to the first connecting flange 3023. In other embodiments, the bolt passes through the third connecting lug 6, the second connecting flange 3012, and the first connecting flange 3023 and is threadedly connected to the first connecting protrusion 3022. The threaded connection method between the bolt and the first connecting flange and the first connecting protrusion can be adjusted according to actual usage requirements.

[0038] Specifically, the suspension hydraulic pump mounting position of the powertrain unit 3 is provided with a reinforcing structure. By providing this reinforcing structure, the rigidity of the suspension hydraulic pump mounting position can be enhanced, improving the stability of the suspension hydraulic assembly 1. In this embodiment, the surface of the crankcase 302 where the suspension hydraulic pump is mounted is the mounting surface. The reinforcing structure includes multiple reinforcing ribs 3021, which are disposed on the mounting surface and extend along the height direction of the crankcase 302. The multiple reinforcing ribs 3021 are arranged in parallel. The reinforcing ribs 3021 have advantages such as flexible arrangement and good reinforcement effect. In some embodiments, the outer shell of the powertrain unit 3 at the suspension hydraulic pump mounting position is thicker than other parts to provide better support. In other embodiments, the material of the outer shell of the powertrain unit 3 at the suspension hydraulic pump mounting position is stronger than other parts to provide better support. The type of reinforcing structure can be adjusted according to the actual usage.

[0039] This utility model provides a vehicle, including a front subframe and a powertrain with an integrated suspension hydraulic pump as described above. The powertrain is connected to the front subframe via a powertrain mounting system.

[0040] In summary, by integrating the suspension hydraulic assembly 1 with the powertrain main body 3, the engine mounting system can effectively absorb the vibrations generated during the operation of the suspension hydraulic assembly 1, preventing these vibrations from being transmitted to the vehicle body and affecting the overall driving experience. It also prevents noise generated by these vibrations, thus improving the overall driving comfort. Since the suspension hydraulic assembly 1 is mounted on the powertrain main body 3, it makes full use of the powertrain compartment space. The suspension hydraulic assembly 1 does not require a separate mounting system, reducing vehicle weight, manufacturing costs, and the interior space required for the aforementioned mounting system, resulting in a more compact overall vehicle layout.
