[0031] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0032] See the figure below for reference Figure 1-Figure 7 The power system 100 according to the embodiment of the present invention is described. The power system 100 according to the embodiment of the present invention can be applied to a vehicle.

[0033] Combination Figure 1-Figure 4 As shown, the power system 100 according to the embodiment of the utility model can mainly include: a power assembly 10 and a suspension assembly 20. The suspension assembly 20 includes a suspension body 21 and a connecting arm 22 connected to each other, the suspension body 21 is connected to the power assembly 10, and the connecting arm 22 is suitable for connecting to the vehicle body frame 200.

[0034] Specifically, the power assembly 10 is connected to the wheels by transmission, so that the power assembly 10 transmits driving force to the wheels, thereby rotating the wheels and allowing the vehicle to travel normally. During the daily driving of the vehicle, the uneven road surface will excite the wheels, and this excitation will be transmitted to the power assembly 10 in the form of vibration. The power assembly 10 is connected to the body frame 200, and then transmitted to the cabin through the body frame 200. The suspension assembly 20 is arranged between the power assembly 10 and the body frame 200, so that the power system 100 can move independently of the vehicle body, effectively reduce the vibration and noise of the engine and the vehicle, and at the same time improve the safety and stability of the vehicle. The suspension assembly 20 includes a suspension body 21 and a connecting bracket 22 that are connected to each other. The suspension body 21 is used to absorb and isolate vibration, and the connecting bracket 22 can be used to connect and fix the suspension assembly 20.

[0035] In related technologies, the design of the suspension system is usually based on the powertrain torque axis arrangement. The torque axis is also called TRA (Torque Reactive Axis), which is a theoretical axis that defines the free torsional vibration of the powertrain (including components such as the engine and transmission) around a certain axis in its own coordinate system when subjected to external torque. This concept is particularly important in the vibration control and powertrain suspension system design of automobiles and other vehicles.

[0036] In the suspension design of the powertrain, the elastic center of the suspension is arranged as much as possible on the torque axis, so that when the powertrain is stimulated by uneven road surface, it will mainly vibrate along this axis, reducing translation and rotation in other directions, thereby achieving the best vibration isolation effect. Therefore, determining and utilizing the position of the torque axis is of great significance for optimizing the installation position of the powertrain and improving the NVH (noise, vibration, and harshness) performance of the vehicle.

[0037] In conventional suspension designs, the main structure is arranged on the longitudinal beam of the vehicle body and connected to the powertrain through a bracket. When the suspension assembly matches the longitudinal beam of the vehicle body of different models or replaces different powertrains, in order to ensure that the elastic center of the suspension body is arranged on the torque axis of the powertrain as much as possible, it is necessary to readjust the position of the suspension body structure relative to the powertrain and the connection position between the suspension body structure and the powertrain. This will limit the platformization of the power system, prolong the product development cycle, and is not conducive to reducing product development costs.

[0038] In an embodiment of the utility model, the suspension body 21 is arranged on the power assembly 10. When the suspension assembly 20 and the power assembly 10 are assembled, the elastic center of the suspension assembly 20 can be arranged on the torque axis of the power assembly 10. After adjustment, a power system 100 can be formed, and the connecting arm 22 of the suspension assembly 20 can be used to connect the vehicle body frame 200.

[0039] With such a configuration, when the connecting bracket 22 is connected to the vehicle body frame, it is only necessary to connect the connecting bracket 22 to the vehicle body frame 200 by common means, without considering the relationship between the elastic center of the suspension assembly 20 and the torque axis of the power assembly 10. When the power system 100 of the utility model is matched with different vehicle models, only the structure of the connecting bracket 22 can be adjusted to connect the connecting bracket 22 to the vehicle body frame 200 of different vehicle models, so that the power system 100 of the utility model is adapted to the vehicle body frame 200 of different vehicle models, without adjusting the suspension assembly 20 and the power assembly 10, which can make the power system 100 of the utility model easy to use as a platform, thereby facilitating the product development cycle of new vehicle models and reducing the design, production and procurement costs of new vehicle models.

[0040] Combination Figure 2 , Figure 4 and Figure 5 As shown, the suspension body 21 includes a bracket 212 and an elastic connector 213. The bracket 212 is connected to the power assembly 10, and the elastic connector 213 is arranged in the bracket 212 and connected to the connecting bracket 22. Specifically, the bracket 212 of the suspension body 21 has a certain structural strength, and the elastic connector 213 has a certain elastic deformation ability. The elastic connector 213 is arranged in the bracket 212, so that the bracket 212 can provide a stable and reliable setting position for the elastic connector 213, and can ensure the reliability of force transmission between the bracket 212 and the elastic connector 213, thereby ensuring the vibration isolation effect of the suspension assembly 20.

[0041] Furthermore, the bracket member 212 is connected to the power assembly 10, so that when the road excitation is transmitted to the power assembly 10 through the wheels, the vibration on the power assembly 10 can be transmitted to the bracket member 212, and then transmitted to the elastic connecting member 213. The elastic connecting member 213 is squeezed and reset reciprocatingly. During the reciprocating motion of the elastic connecting member 213, the force can be gradually consumed, so that the suspension assembly 20 can absorb part of the vibration.

[0042] Furthermore, the elastic connector 213 is connected to the connecting support arm 22, so that the force after vibration isolation by the elastic connector 213 is transmitted to the connecting support arm 22, so that the vibration transmitted to the connecting support arm 22 is reduced compared to the excitation of the road surface on the wheel. In this way, the suspension assembly 20 can play a role in blocking the transmission of vibration between the powertrain 10 and the vehicle body frame 200, thereby reducing the vibration and noise transmitted to the cabin, which is beneficial to improving the comfort of the vehicle.

[0043] Combination Figure 2As shown, a first through hole 211 is provided on the suspension body 21, and a second through hole 11 is provided on the power assembly 10. The first through hole 211 corresponds to the second through hole 11 and is connected and fixed by a first fastener. Specifically, the structure of the first through hole 211 is simple, and it can be convenient to open it on the suspension body 21. The structural member of the second through hole 11 can be conveniently opened on the power assembly 10. When connecting the suspension body 21 and the power assembly 10, the first through hole 211 and the second through hole 11 are made to correspond, and then the first fastener is sequentially passed through the first through hole 211 and the second through hole 11 and tightened, so that the suspension body 21 and the power assembly 10 can be easily connected and fixed to ensure the connection reliability between the suspension body 21 and the power assembly 10, so that the installation operation of the suspension body 21 and the power assembly 10 can be simplified.

[0044] In the embodiment of the utility model, the position of the first through hole 211 on the suspension body 21 needs to satisfy that the elastic center of the suspension assembly 20 passes through the torque axis of the power assembly 10, and the position of the second through hole 11 on the power assembly 10 needs to satisfy that the elastic center of the suspension assembly 20 passes through the torque axis of the power assembly 10, so that after the first fastener passes through the first through hole 211 and the second through hole 11 in sequence to connect and fix the suspension body 21 to the power assembly 10, it can be ensured that the elastic center of the suspension body 21 passes through the torque axis of the power assembly 10. Such a setting can make the power assembly 10 vibrate mainly along this axis when it is excited by the uneven road surface, and reduce the translation and rotation in other directions. The elastic center of the suspension body 21 vibrates synchronously on the torque axis of the power assembly 10, so that most of the vibration of the power assembly 10 can be directly transmitted to the suspension body 21, so that the vibration of the power assembly 10 can be absorbed by the suspension body 21 as much as possible, thereby achieving the best vibration isolation effect.

[0045] According to an embodiment of the present invention, the elastic connector 213 is a rubber member, and the rubber member is elastically vulcanized and connected to the connecting bracket 22. Specifically, the use of a rubber member as the elastic connector 213 of the suspension assembly 20 in the embodiment of the present invention can improve the corrosion resistance and durability of the elastic connector 213. The rubber member is bonded and connected to the connecting bracket 22 by vulcanization, which can not only simplify the installation process of the elastic connector 213 and the connecting bracket 22, but also ensure the connection reliability of the elastic connector 213 and the connecting bracket 22, thereby ensuring the structural reliability of the suspension assembly 20, so as to ensure the stability and reliability of the power system 100 of the embodiment of the present invention after platformization, so as to meet the requirements of different vehicle models for NVH performance.

[0046] Combination Figure 2 , Figure 6 and Figure 7As shown, the connecting support arm 22 includes a support arm body 221 and a sleeve 222. One end of the support arm body 221 is suitable for connecting to the vehicle body frame 200, and the other end is press-fitted into the sleeve 222. The sleeve 222 is connected to the elastic connector 213. Specifically, the support arm body 221 is connected to the vehicle body frame 200, so that the suspension assembly 20 can be connected to the vehicle body frame 200, and then the platform-type power system 100 in the embodiment of the utility model can be connected to the vehicle body frame 200, so that the power system 100 of the utility model can be connected to the vehicle body frame 200 of different models.

[0047] Furthermore, the other end of the support arm body 221 away from the vehicle body frame 200 is connected to the sleeve 222 by pressing, so that the other end of the support arm body 221 is suitable for being connected to the elastic connecting piece 213, and the pressing of the support arm body 221 and the sleeve 222 can ensure the connection reliability between the support arm body 221 and the sleeve 222 to prevent the support arm body 221 from detaching from the sleeve 222.

[0048] Furthermore, the sleeve 222 is suitable for being bonded and connected to the elastic connector 213 by vulcanization of the elastic connector 213. In this way, the connection reliability of the sleeve 222 and the elastic connector 213 can be ensured, and the structural reliability of the other end of the support arm body 221 in the elastic connector 213 can be ensured, thereby ensuring the connection reliability of the support arm 22 and the elastic connector 213, and the structural reliability of the suspension assembly 20 can be ensured.

[0049] According to some embodiments of the present invention, Figure 2 , Figure 4 and Figure 5 As shown, the bracket member 212 includes a first bracket member 2121 and a second bracket member 2122, and the first bracket member 2121 and the second bracket member 2122 are arranged opposite to each other in the up-down direction and are connected and fixed. Specifically, in the embodiment of the utility model, the bracket member 212 can be divided into two upper and lower parts, one of which is the first bracket member 2121 and the other is the second bracket member 2122. The first bracket member 2121 and the second bracket member 2122 are arranged opposite to each other to form the overall structure of the bracket member 212. The suspension body 21 is located between the first bracket member 2121 and the second bracket member 2122 in the up-down direction, and the first bracket member 2121 and the second bracket member 2122 are connected, so that not only the structural reliability of the bracket member 212 can be ensured, but also the first bracket member 2121 and the second bracket member 2122 can be connected to the elastic connecting member 213, so that the structural stability of the elastic connecting member 213 in the bracket member 212 can be ensured, and then the vibration isolation effect of the suspension assembly 20 can be ensured. In the embodiment of the present invention, the connection method between the first bracket member 2121 and the second bracket includes but is not limited to riveting, screwing, welding and bonding.

[0050] According to some embodiments of the present invention, when the first bracket member 2121 and the second bracket member 2122 are fixed by screw connection, threaded holes can be respectively opened on the sides of the first bracket member 2121 and the second bracket member 2122 to connect and fix the first bracket member 2121 and the second bracket member 2122 by fasteners. In an embodiment of the present invention, the number of threaded holes on the bracket member 212 is at least two.

[0051] According to other embodiments of the present invention, when the first bracket member 2121 and the second bracket member 2122 are fixed by screw connection, the fastener can pass through the bracket member 212, the sleeve 222 and the elastic connector 213 from the middle position of the bracket member 212 from top to bottom in sequence to fix the bracket member 212, the sleeve 222 and the elastic connector 213 at the same time, thereby further enhancing the structural reliability of the suspension assembly 20. In the embodiment of the present invention, the number of threaded holes on the bracket member 212 is at least two.

[0052] According to other embodiments of the present invention, the bracket member 212 is an integrally formed structural member. Specifically, in the embodiments of the present invention, the bracket member 212 can be an integrally formed structural member. Such a bracket member 212 not only has a simple production process and does not require assembly, but also has good structural strength. A through hole is provided inside the integrally formed bracket member 212 to facilitate the arrangement of the elastic connector 213.

[0053] Combination Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the connecting bracket 22 is disposed on one side of the suspension body 21. Specifically, after the connecting bracket 22 is connected to the elastic connector 213, it extends from the elastic connector 213 toward the side of the vehicle body frame 200, so as to facilitate the connecting bracket 22 to be connected to the vehicle body frame 200. During the driving process of the vehicle, the power assembly 10 may move toward the vehicle body frame 200 along the connecting bracket 22. If the power assembly 10 is in direct contact with the vehicle body frame 200, the force on the power assembly 10 will be directly transmitted to the vehicle body frame 200, affecting the vibration isolation effect of the suspension assembly 20.

[0054] In the embodiment of the present utility model, combined with Figure 2 , Figure 4 and Figure 5 As shown, the support arm body 221 includes a first support arm portion 2211, a second support arm portion 2212 and a third support arm portion, wherein the third support arm portion is press-fitted with the sleeve 222, the first support arm portion 2211 is connected to the vehicle body frame 200, and the second support arm portion 2212 is located between the first support arm portion 2211 and the third support arm portion.

[0055] Combination Figure 4As shown, when the first support arm portion 2211 and the second support arm portion 2212 are arranged horizontally, the second support arm portion 2212 is parallel to the first support arm portion 2211 and the third support arm portion. At this time, the third support arm portion and the first support arm portion 2211 have the same height in the vertical direction, and the size of the second support arm portion 2212 can be adjusted to make the power system 100 of the embodiment of the utility model match the frames of different models.

[0056] Combination Figure 5 As shown, when the first support arm portion 2211 and the third support arm portion have different heights in the up and down directions, the second support arm portion 2212 can be tilted to connect the first support arm portion 2211 and the third support arm portion, thereby ensuring that the powertrain 10 in the embodiment of the utility model is adapted to the body frames 200 of different vehicle models.

[0057] Combination Figure 2 As shown, the third through hole 223 is disposed on the first bracket portion 2211, and the number of the third through holes 223 is multiple, and the multiple third through holes 223 are spaced apart on the first bracket portion 2211. In the embodiment of the utility model, the number of the third through holes 223 can be set according to the vehicle body frame 200 of different models to ensure the connection reliability between the bracket 22 and the vehicle body frame 200 of different models.

[0058] In the embodiment of the utility model, a limiting member 214 is provided on one side of the suspension body 21 corresponding to the connecting bracket 22, and the limiting member 214 is suitable for abutting against the body frame 200 for limiting position. In this way, when the power assembly 10 moves toward the body frame 200, the limiting member 214 can move toward the body frame 200 together with the power assembly 10, and the limiting member 214 is always located between the body frame 200 and the power assembly 10, so that when the power assembly 10 moves to the point where the limiting member 214 abuts against the body frame 200, the body frame 200 can prevent the power assembly 10 from continuing to move toward the body frame 200. In the embodiment of the utility model, the limit member 214 is connected to the elastic connecting member 213, and both are rubber members. In this way, when the limit member 214 abuts against the vehicle body frame 200, the force on the power assembly 10 will be transmitted to the elastic connecting member 213 located in the bracket member 212 through the limit member 214 to prevent the vibration from being directly transmitted to the vehicle body frame 200 and then transmitted to the cabin to affect the vehicle comfort, thereby ensuring the NVH performance of the entire vehicle.

[0059] According to some embodiments of the present invention, the limiter 214 can be fixed on the bracket 212, and selectively abut against the body frame 200, and the fixing methods of the limiter 214 include but are not limited to vulcanization and bonding. According to other embodiments of the present invention, the limiter 214 can be fixed on the powertrain 10, and selectively abut against the body frame 200, and the fixing methods of the limiter 214 include but are not limited to vulcanization and bonding. According to still other embodiments of the present invention, the limiter 214 can be fixed on the body frame 200, and selectively abut against the powertrain 10, and the fixing methods of the limiter 214 include but are not limited to vulcanization and bonding.

[0060] In the embodiment of the present invention, a protrusion 12 is disposed at the upper end of the power assembly 10 , and the protrusion 12 corresponds to the stopper 214 , so as to support the stopper 214 when the stopper 214 abuts against the vehicle body frame 200 for stoppering.

[0061] According to other embodiments of the present invention, the side of the bracket member 212 away from the vehicle body frame 200 can be selectively closed, which can limit the elastic connecting member 213 inside the bracket member 212 and prevent the elastic connecting member 213 from escaping from the bracket member 212, so as to enhance the structural reliability of the suspension assembly 20.

[0062] Combination Figure 2 As shown, the connecting bracket 22 is provided with a third through hole 223, which is suitable for corresponding to the fourth through hole 2001 on the vehicle body frame 200 and connected and fixed by the second fastener. Specifically, the third through hole 223 has a simple structure and can be easily opened on the connecting bracket 22. The structural member of the fourth through hole 2001 can be easily opened on the vehicle body frame 200. When installing the connecting bracket 22 and the vehicle body frame 200, the third through hole 223 and the fourth through hole 2001 are aligned, and then the second fastener is sequentially passed through the third through hole 223 and the fourth through hole 2001 and tightened, so that the connecting bracket 22 and the vehicle body frame 200 can be easily connected and fixed to ensure the connection reliability of the connecting bracket 22 and the vehicle body frame 200, so that the installation operation of the connecting bracket 22 and the vehicle body frame 200 can be simplified.

[0063] According to an embodiment of the utility model, a vehicle includes a power system 100 in an embodiment of the utility model. The power system 100 of the utility model arranges the suspension body of the suspension assembly 20 on the power assembly 10, so as to first determine that the elastic center of the suspension assembly 20 passes through the torque axis of the power assembly 10, thereby making the suspension assembly 20 platform-like, and making the power system 100 of the utility model adaptable to the vehicle body frame 200 of different vehicle models. In actual applications, the elastic center of the suspension assembly 20 passing through the torque axis of the power assembly 10 may have a certain tolerance.

[0064] For the vehicle body frame 200, the suspension assembly 20 and the power assembly 10 in the power system 100 of the utility model are platform-based shared structures, which can reduce the cost of vehicle design, production and procurement, and the platform-based shared structure can be mass-produced, with unit costs reduced, while reducing the complexity of inventory management and logistics. In addition, the platform-based shared structure has been rigorously tested and verified by the platform, which can ensure the stability and reliability of the power system 100 of the utility model in new models, which is conducive to improving product quality.

[0065] Furthermore, after adopting the platform-based power system 100 in vehicle manufacturing, there is no need to design each component from scratch, which is conducive to accelerating the development cycle of new models.
