Description

Technical Field

[0001] This application relates to the field of active vehicle suspension technology, and in particular to a hybrid vehicle front compartment structure and vehicle equipped with fully active suspension. Background Technology

[0002] With the continuous development of the automotive industry, market customers are increasingly demanding smoothness and handling from their vehicles. In the field of vehicle suspension technology, traditional shock absorbers, due to their poor vibration filtering performance, struggle to meet users' needs for ride comfort. To improve this situation, semi-active suspensions have emerged, offering continuously adjustable damping and representing a performance improvement over traditional shock absorbers. However, semi-active suspensions still lag significantly behind active suspensions in terms of adjustment precision and response speed.

[0003] Active suspension, as a superior technical solution, is gradually becoming the mainstream in the market. In an active suspension system, the electric pump assembly is one of the key components, and the electric motor is an important and indispensable power element within the electric pump assembly. A high-performance electric motor can drive a four-quadrant internal gear pump and supports forward and reverse rotation, thereby continuously supplying high-pressure oil to the shock absorbers. This achieves a wider adjustment bandwidth and faster response speed for the suspension, truly improving vehicle smoothness and handling, and providing passengers with a better driving experience.

[0004] However, active suspension requires four additional electric pump assemblies to control the four active shock absorbers corresponding to the four wheels, and these electric pump assemblies are both relatively heavy and bulky. The front compartment layout of PHEV hybrid vehicles is more complex than that of traditional gasoline vehicles and pure electric vehicles; currently, all models on the market equipped with fully active suspension systems are either traditional gasoline vehicles or pure electric vehicles. How to arrange the electric pump assemblies for active suspension within the limited front compartment environment while meeting the performance requirements of various systems and the entire vehicle is an urgent problem to be solved.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] This application provides a hybrid vehicle front compartment structure and vehicle with a fully active suspension, which can solve the problem in the related technology that the front compartment space of PHEV hybrid vehicles is limited, and it is difficult to meet the performance requirements of various systems and the whole vehicle when arranging the electric pump assembly of the active suspension in the limited front compartment environment.

[0023] See Figure 1 and Figure 2As shown, the first aspect of this application provides a hybrid vehicle front compartment structure configured with fully active suspension, including: The front subframe 1 is a full-frame aluminum alloy subframe, comprising a left sub-longitudinal beam 11 and a right sub-longitudinal beam 12, and a front crossbeam 13 and a rear crossbeam 14 connected between the left and right sub-longitudinal beams 11 and 12 and spaced apart from front to back. The front subframe is a crucial component of the PHEV hybrid vehicle chassis, supporting the hybrid powertrain, suspension system, and other functional parts.

[0024] Cooling module 2 is fixed to the front end of the front subframe 1. It is located above the front subframe 1 and gradually slopes upwards towards the rear end of the front subframe 1. The cooling module 2 includes a radiator, condenser, and fan arranged sequentially from front to back. The front active suspension motor pump 3 is also positioned at the front end of the front subframe 1, providing space for its installation.

[0025] The front active suspension motor pump 3 is located above the front subframe 1 and behind the cooling module 2, and is fixed to the front crossbeam 13 via a suspension damping structure. The front active suspension motor pump 3 supplies high-pressure oil to the active dampers to achieve a wider adjustment bandwidth and faster response speed of the suspension, thereby truly improving the vehicle's smoothness and handling, and providing passengers with a better driving experience.

[0026] In order to accommodate the front active suspension motor pump 3 within the compact space of the hybrid vehicle's front compartment, the front compartment structure of the hybrid vehicle with fully active suspension in this application embodiment fixes the cooling module 2 to the front end of the front subframe 1. The cooling module 2 is located above the front subframe 1 and gradually tilts from bottom to top towards the rear end of the front subframe 1, providing space for the front active suspension motor pump 3 to be fixed above the front subframe.

[0027] Because the front subframe 1 itself has good structural rigidity, the front active suspension motor pump 3 is fixed to the front subframe 1, providing a stable mounting base for the front active suspension motor pump 3. The front active suspension motor pump 3 is fixed to the front crossbeam 13 through the suspension damping structure, ensuring that the front active suspension motor pump 3 meets NVH performance requirements. This application provides space for the front active suspension motor pump 3 to be arranged in the front compartment, and realizes the fully active suspension configuration of the hybrid vehicle through the front subframe 1 and the suspension damping structure, while ensuring the performance requirements of the front active suspension motor pump and the entire vehicle.

[0028] In some alternative embodiments: see Figure 1 and Figure 2As shown, this application embodiment provides a hybrid vehicle front compartment structure with a fully active suspension. The front active suspension motor pump 3 of the hybrid vehicle front compartment structure includes a pump housing assembly 31, a drive motor 32 integrated in the pump housing assembly 31, and two sets of hydraulic pumps 33 located in the pump housing assembly 31 and respectively connected to the two ends of the drive motor 32. The pump housing assembly 31 is also provided with a control circuit board 34 connected to the drive motor 32.

[0029] In this embodiment, the front active suspension motor pump 3 integrates a drive motor 32 within the pump housing assembly 31, and two sets of hydraulic pumps 33 are rotatably connected to both ends of the drive motor 32. The pump housing assembly 31 also has a control circuit board 34 connected to the drive motor 32, which greatly reduces the structural volume of the front active suspension motor pump 3 and reduces its occupation of the internal space of the front compartment structure of the hybrid vehicle.

[0030] During use, the control circuit board 34 controls the drive motor 32 to drive two sets of hydraulic pumps 33 to supply oil to the active shock absorbers on both sides of the active suspension, so as to realize the rapid and stable adjustment of the active shock absorbers on both sides of the car suspension. The performance is stable and reliable, which can ensure the driving stability of the vehicle.

[0031] In some alternative embodiments: see Figure 1 and Figure 2 As shown in the figure, this application embodiment provides a hybrid vehicle front compartment structure configured with fully active suspension. The length direction of the front active suspension motor pump 3 of this hybrid vehicle front compartment structure is parallel to the width direction of the front subframe 1, and it is fixed to the front crossbeam 13 along the width direction of the front subframe 1. The front crossbeam 13 includes a first front crossbeam 15 and a second front crossbeam 16 that are parallel to each other and spaced apart. Both the first front crossbeam 15 and the second front crossbeam 16 are provided with mounting brackets for connecting the suspension damping structure.

[0032] The suspension damping structure includes transition brackets 38 located at both ends of the front active suspension motor pump 3. The transition brackets 38 are made of aluminum alloy or steel casting. The top of the transition bracket 38 has an upper suspension mounting hole, and an upper suspension rubber sleeve 39 is vulcanized and connected in the upper suspension mounting hole. An upper suspension inner sleeve for connecting the front active suspension motor pump 3 is vulcanized and connected in the upper suspension rubber sleeve 39. The upper suspension inner sleeve is fixedly connected to the front active suspension motor pump 3 by bolts.

[0033] The transition bracket 38 has lower suspension mounting holes at both ends of its bottom. The line connecting the two lower suspension mounting holes and one upper suspension mounting hole on the transition bracket 38 forms an isosceles triangle structure. A lower suspension rubber sleeve 40 is vulcanized and connected inside the lower suspension mounting hole. A lower suspension inner sleeve for connecting the mounting bracket is vulcanized and connected inside the lower suspension rubber sleeve 40. The lower suspension inner sleeve is fixedly connected to the mounting bracket by bolts.

[0034] The suspension damping structure of this embodiment has an upper suspension mounting hole at the top of the transition bracket 38 and lower suspension mounting holes at both ends of the bottom of the transition bracket 38. An upper suspension sleeve 39 is vulcanized and connected within the upper suspension mounting hole, and an upper suspension inner sleeve for connecting the front active suspension motor pump 3 is vulcanized and connected within the upper suspension sleeve 39. A lower suspension sleeve 40 is vulcanized and connected within the lower suspension mounting hole, and an upper suspension inner sleeve for connecting the mounting bracket is vulcanized and connected within the lower suspension sleeve 40.

[0035] When the active suspension motor pump 3 is started, the vibration generated by the active suspension motor pump 3 itself will be damped and filtered by the upper suspension bushing 39 and the lower suspension bushing 40 before being transmitted to the front crossbeam 13. This avoids the vibration generated by the active suspension motor pump 3 being directly transmitted to the front subframe 1, thereby improving the vehicle's NVH performance and preventing the vibration generated by the hybrid powertrain 6 installed on the front subframe 1 from interfering with the normal operation of the active suspension motor pump 3.

[0036] In some alternative embodiments: see Figures 1 to 3 As shown, this application embodiment provides a hybrid vehicle front compartment structure with fully active suspension. The pump housing assembly 31 of the hybrid vehicle front compartment structure integrates a liquid cooling plate 35 for cooling the drive motor 32 and the control circuit board 34. The liquid cooling plate 35 is sandwiched between the drive motor 32 and the control circuit board 34. The pump housing assembly 31 is provided with a cooling water inlet pipe 36 and a coolant outlet pipe 37 connecting the liquid cooling plate 35.

[0037] A hybrid powertrain 6 is mounted on the front subframe 1. The cooling module 2 includes a radiator, which is connected to the hybrid powertrain 6 via a circulating water pump 9. The hybrid powertrain 6 is connected to the coolant outlet pipe 37, and the coolant inlet pipe 36 is connected to the radiator. A liquid cooling plate 35 is used to cool the drive motor 32 and the control circuit board 34, ensuring that the drive motor 32 and the control circuit board 34 operate stably at a suitable temperature.

[0038] To maintain the temperature of the coolant within the liquid cooling plate 35 at a set temperature, the cooling water inlet pipe 36 and the coolant outlet pipe 37 of the liquid cooling plate 35 are respectively connected to the hybrid powertrain 6 and the radiator. The hybrid powertrain 6 and the radiator are connected, forming the first cooling circulation loop. After being cooled by the radiator, the coolant first enters the liquid cooling plate 35 to cool the drive motor 32 and the control circuit board 34. Then, it flows out of the liquid cooling plate 35 and enters the hybrid powertrain 6 to cool the engine and the front drive motor. Finally, it flows back to the radiator for heat dissipation. The circulating water pump 9 keeps the coolant in a circulating state.

[0039] In some alternative embodiments: see Figure 1As shown in the embodiment of this application, a hybrid vehicle front compartment structure with a fully active suspension is provided. The left sub-longitudinal beam 11 of the hybrid vehicle front compartment structure includes a left front sub-longitudinal beam 17 and a left rear sub-longitudinal beam 18 that are welded together. The right sub-longitudinal beam 12 includes a right front sub-longitudinal beam 19 and a right rear sub-longitudinal beam 20 that are welded together. The left front sub-longitudinal beam 17 and the right front sub-longitudinal beam 19 are integrally cast with the front crossbeam 13, and the left rear sub-longitudinal beam 18 and the right rear sub-longitudinal beam 20 are integrally cast with the rear crossbeam 14.

[0040] In this embodiment, the left secondary longitudinal beam 11 is composed of a left front secondary longitudinal beam 17 and a left rear secondary longitudinal beam 18 welded together, and the right secondary longitudinal beam 12 is composed of a right front secondary longitudinal beam 19 and a right rear secondary longitudinal beam 20 welded together. The left front secondary longitudinal beam 17 and the right front secondary longitudinal beam 19 are integrally cast with the front crossbeam 13, and the left rear secondary longitudinal beam 18 and the right rear secondary longitudinal beam 20 are integrally cast with the rear crossbeam 14.

[0041] Furthermore, the front subframe 1 of this application can be selectively assembled depending on whether the vehicle is equipped with a hybrid powertrain 6 or a front electric drive assembly. When the vehicle is equipped with a hybrid powertrain 6, the left sub-longitudinal beam 11 consists of a left front sub-longitudinal beam 17 and a left rear sub-longitudinal beam 18 welded together, and the right sub-longitudinal beam 12 consists of a right front sub-longitudinal beam 19 and a right rear sub-longitudinal beam 20 welded together. When the vehicle is equipped with a front electric drive assembly, the front subframe 1 is integrally cast with the left rear sub-longitudinal beam 18 and the right rear sub-longitudinal beam 20 and the rear crossbeam 14, excluding the left front sub-longitudinal beam 17, the right front sub-longitudinal beam 19, and the front crossbeam 13.

[0042] In some alternative embodiments: see Figure 1 As shown, this application embodiment provides a hybrid vehicle front compartment structure with a fully active suspension. The hybrid vehicle front compartment structure also includes an air conditioning compressor 4, which is fixed on the front crossbeam 13. The air conditioning compressor 4 and the front active suspension motor pump 3 are spaced apart along the width direction of the front subframe 1 and staggered from each other in the lateral direction of the vehicle, thereby reducing the encroachment on the energy absorption space of the front compartment.

[0043] See Figures 1 to 3 As shown, a second aspect of this application provides a vehicle, including: a hybrid vehicle front compartment structure with fully active suspension as described in any of the above embodiments, and a rear electric drive assembly 8, a charger assembly 7, and a rear active suspension motor pump 5 located on the rear axle of the vehicle. The cooling pipes of the rear electric drive assembly 8, the charger assembly 7, and the rear active suspension motor pump 5 are connected in series and communicate with the cooling module 2.

[0044] This application, prior to the installation of the front active suspension motor pump 3 in the above embodiments, also includes the following design and testing scheme: 1. When the front active suspension motor pump 3 is located in the rear compartment: The front active suspension motor pump 3 needs to be connected to four active shock absorbers. If both the front active suspension motor pump 3 and the rear active suspension motor pump 5 are in the rear compartment, the oil pipes connecting to the front shock absorbers are too long, resulting in wasted costs, increased weight (oil + pipes), and occupation of the central tunnel space, leading to a poor human-machine experience. The significant difference in pipe length between the front active suspension motor pump 3 and the rear active suspension motor pump 5 and the front and rear active shock absorbers results in a significant difference in response time, affecting the functional experience of the fully active suspension.

[0045] II. When the front active suspension motor pump 3 is mounted on the front bumper: The front active suspension motor pump 3 is a vibrating component and has high requirements for NVH performance. Mounting the front active suspension motor pump 3 on the front bumper beam results in poor dynamic stiffness, failing to meet the required stiffness.

[0046] 3. When the front active suspension motor pump 3 is located behind the front bumper beam: For hybrid vehicles with a heat pump system, the heat pump system components are located here. If the front active suspension motor pump 3 is located here, it will be incompatible with the heat pump configuration. Hybrid vehicles typically have small low-temperature radiators mounted on the outer panels of the left and right longitudinal beams. If the front active suspension motor pump 3 is located behind these radiators, it will increase back pressure, affecting the thermal management air intake and failing to meet the temperature resistance requirements of the motor pump. IV. When the front active suspension motor pump 3 is positioned behind the hybrid powertrain between the hybrid vehicle and the battery pack: The steering gear of the hybrid vehicle is located behind the engine, and the existing hybrid vehicle's battery pack occupies a large volume in the X-direction, leaving no further space for arrangement between the engine and the battery pack. The space behind the engine is close to the passenger compartment, making it easy for the operating noise of the front active suspension motor pump 3 to be transmitted into the passenger compartment. Furthermore, there is an exhaust pipe behind the engine, and the exhaust pipe temperature is high, which cannot meet the temperature resistance requirements of the front active suspension motor pump 3 in the surrounding environment.

[0047] Working principle This application provides a hybrid vehicle front compartment structure and vehicle with fully active suspension. The hybrid vehicle front compartment structure with fully active suspension of this application is provided with a front subframe 1, which includes a left sub-longitudinal beam 11 and a right sub-longitudinal beam 12, and a front crossbeam 13 and a rear crossbeam 14 connected between the left sub-longitudinal beam 11 and the right sub-longitudinal beam 12 and arranged sequentially from front to back; a cooling module 2, which is fixed to the front end of the front subframe 1 and is located above the front subframe 1 and gradually tilted from bottom to top towards the rear end of the front subframe 1; and a front active suspension motor pump 3, which is located above the front subframe 1 and is fixed to the front crossbeam 13 by a suspension damping structure.

[0048] Therefore, in order to arrange the front active suspension motor pump 3 in the compact space of the hybrid vehicle front compartment, the cooling module 2 is fixed to the front end of the front subframe 1. The cooling module 2 is located above the front subframe 1 and gradually tilts from bottom to top towards the rear end of the front subframe 1, providing space for the front active suspension motor pump 3 to be fixed above the front subframe 1.

[0049] Because the front subframe 1 itself has good structural rigidity, the front active suspension motor pump 3 is fixed to the front subframe 1, providing a stable mounting base for the front active suspension motor pump 3. The front active suspension motor pump 3 is fixed to the front crossbeam 13 through the suspension damping structure, ensuring that the front active suspension motor pump 3 meets NVH performance requirements. This application provides space for the front active suspension motor pump 3 to be arranged in the front compartment, and realizes the fully active suspension configuration of the hybrid vehicle through the front subframe 1 and the suspension damping structure, while ensuring the performance requirements of the front active suspension motor pump and the entire vehicle.
