[0042] The specific implementation of the present invention will be further explained in detail below by describing the optimal embodiment with reference to the accompanying drawings.

[0043] The present invention discloses a suspension power generation assembly, including a wheel hub power generation assembly and a spring power generation assembly; in the present invention, the wheel hub power generation assembly is used to recover wheel kinetic energy, and the spring power generation assembly is used to recover energy when the suspension spring 901 vibrates.

[0044] The wheel hub power generation assembly includes a motor 6 connected to the wheel hub assembly 4; the motor 6 is connected to the wheel hub assembly 4 through a transmission assembly; the present invention, through the arrangement of the wheel hub power generation assembly, enables the present invention to recover part of the vehicle power when in use, especially when the vehicle is going downhill, the kinetic energy of the wheels can be partially recovered, thereby reducing the vehicle's kinetic energy loss.

[0045] The wheel hub power generation assembly 1-9 disclosed in the present invention is mainly arranged on the sub-frame 5 in the suspension system. The wheel hub power generation assembly 1-9 disclosed in the present invention is mainly used for reusing the kinetic energy when the vehicle wheels are running.

[0046] The wheel hub power generation assembly 1-9 disclosed in the present invention mainly includes a motor 6. During normal use, the motor 6 of the present invention is mainly used as a generator 6. In the present invention, the motor 6 is connected to the wheel hub assembly 4 through a transmission assembly; the transmission assembly plays a role of connecting the transmission, facilitating the transmission of the rotation power of the wheel hub assembly 4 to the motor 6, thereby realizing the power generation operation of the motor 6, and then realizing the recovery of the wheel kinetic energy to a certain extent.

[0047] In addition, the spring power generation assembly described in the present invention includes a permanent magnet 904 arranged in the suspension spring 901; the spring power generation assembly disclosed in the present invention mainly includes a permanent magnet 904 and a suspension spring 901, one end of the suspension spring 901 is connected to the lower control arm 902, and the other end is connected to the vehicle body 903. In the present invention, the permanent magnet 904 is fixed on the vehicle body 903 and is arranged coaxially with the suspension spring 901.

[0048] The body 903 is the main part of the whole device and carries other components.

[0049] In the present invention, the permanent magnets 904 can be placed at the upper and lower ends of the suspension spring 901 and fixed to the vehicle body 903 or the lower control arm 902 .

[0050] The suspension spring 901 is used for buffering and shock absorption to ensure riding comfort; at the same time, the suspension spring 901 is connected to a charger 905, which is responsible for storing and managing the generated electrical energy.

[0051] When a car is driving, the suspension system is constantly affected by bumps and vibrations on the road.

[0052] This vibration causes the suspension spring 901 to move up and down, generating relative motion with the permanent magnet 904 fixed to the vehicle body 903 and the frame.

[0053] According to the principle of electromagnetic induction, this relative movement causes an induced electromotive force to be generated in the suspension spring 901, thereby generating electrical energy.

[0054] The generated electric energy is transmitted to the charger 905 through the wiring harness, and the charger 905 performs rectification, filtering and voltage stabilization on the electric energy before storing it in the power storage unit.

[0055] The power storage unit can be a battery or other energy storage device used to provide power support for the vehicle's electrical system.

[0056] It is particularly noted that the lower control arm 902 plays a connecting and supporting role in the suspension system, and works together with the suspension spring 901 and other components to ensure the normal operation of the suspension and the stability of the vehicle.

[0057] In general, the working principle of the invention is to convert the kinetic energy of suspension vibration into electrical energy, and store and manage it through the charger 905. This innovative design not only improves the energy utilization efficiency of new energy vehicles and extends the driving range, but also reduces the dependence on traditional energy, and has significant environmental protection and energy-saving effects.

[0058] At the same time, the components of this invention are simple in design and easy to install and maintain, bringing new opportunities and challenges to the development of new energy vehicles.

[0059] When the vehicle is running, the suspension spring 901 will reciprocate up and down as stimulated by the road surface.

[0060] The permanent magnet 904 generates magnetic induction lines.

[0061] As the suspension spring 901 moves up and down, it continuously cuts the magnetic induction lines generated by the permanent magnet 904 .

[0062] According to the phenomenon of electromagnetic induction, this will generate current in the spring; the bumpier the working conditions, the greater the vibration amplitude of the suspension spring 901, the faster the frequency, and the more current will be generated.

[0063] The generated current is transmitted to the charger 905 through the line, and the charger 905 charges the current into the car battery to charge it.

[0064] As long as the car is moving, the suspension spring 901 will continue to vibrate, thereby continuously generating electrical energy and charging the battery, which improves the driving efficiency to a certain extent.

[0065] Even when driving on a very flat road, the suspension spring 901 still works well. Small bumps will cause the suspension to contract and continuously provide power to the generator.

[0066] As the travel is repeated, the suspension spring 901 continuously cuts the permanent magnet 904 to generate continuous electricity, thereby achieving an ideal working state of continuously charging the battery during driving.

[0067] In addition, in order to increase the scope of application of the present invention, the motor 6 in the present invention can also function as a starter, so that in subsequent use, the motor 6 can provide driving force for the wheels, which can not only be used for vehicle acceleration, but also assist in achieving the vehicle's escape from trouble.

[0068] Furthermore, in the present invention, the motor 6 is connected to the subframe 5 in the suspension system through the mounting bracket 8; the setting of the mounting bracket 8 plays a bridging role, which facilitates the installation and connection of the motor 6 on the subframe 5. In addition, in the present invention, the mounting bracket 8 includes a motor bracket 82 and a hanging bracket 81; the motor 6 is connected to the hanging bracket 81 through the motor bracket 82; the hanging bracket 81 is connected to the subframe 5; in the present invention, the motor bracket 82 is connected to the motor 6, and the hanging bracket 81 is connected to the subframe 5, and the motor bracket 82 and the hanging bracket 81 are connected to each other, thereby realizing the installation and connection of the motor 6 on the subframe 5.

[0069] In the present invention, the connecting bracket and the auxiliary frame 5 can be movably connected, for example, by bolts or the like, or can be connected by welding; the specific connection can be selected according to needs.

[0070] During assembly, the motor bracket 82 is first connected to the motor 6, and the hanging bracket 81 is connected to the sub-frame 5. Subsequently, the motor 6 is connected to the hanging bracket 81 through the motor bracket 82. This installation method facilitates the installation of the motor 6 on the sub-frame 5 and reduces the existence of interference problems.

[0071] At the same time, in the present invention, the height of the lower edge of the hanging bracket 81 from the horizontal plane is less than the height of the lowest edge of the motor 6 from the horizontal plane. With this arrangement, the hanging bracket 81 also plays a certain protective role and reduces the probability of damage to the motor 6.

[0072] Furthermore, the transmission assembly in the present invention includes a transmission shaft 102, and the transmission shaft 102 is connected to the wheel hub assembly 4 through a ball cage structure 7, and the transmission shaft 102 is connected to the motor 6 through a tripod-type constant velocity universal joint 101; the transmission shaft 102 plays a role in transmitting torque. In the present invention, the ball cage structure 7 and the tripod-type constant velocity universal joint 101 both enable the transmission assembly to have a certain floating effect, which is convenient for the lateral rotation of the wheel without affecting the operating interference between the motor 6 and the wheel hub assembly 4.

[0073] In the present invention, the tripod type constant velocity universal joint 101 mainly includes a movable joint housing 713, in which a tripod bearing assembly 1-1 is arranged; the tripod bearing assembly 1-1 includes a tripod frame 2, on which a journal 21 is arranged; each journal 21 is provided with a needle roller bearing 1; the needle roller bearing 1 includes a bearing outer ring 11, a bearing inner ring 15, a needle roller 14 and a limit retaining ring 16; the bearing outer ring 11 includes an outer ring body; an assembly through hole 13 is arranged on the outer ring body; a limit ring rib 18 is arranged at the edge of the assembly through hole 13; the limit ring rib 18 and the limit retaining ring 16 are distributed at both ends of the assembly through hole 13; one end of the limit ring rib 18 is connected to the inner wall of the assembly through hole 13, and the other end extends to the side close to the central axis of the bearing outer ring 11.

[0074] The tripod-type constant velocity universal joint 101 using the needle roller bearing 1 eliminates the axial limit ring on one side of the traditional needle roller bearing 1; it can not only reduce the friction pair inside the bearing, reduce the temperature rise of the universal joint operation, improve the transmission efficiency of the universal joint, and reduce the axial derived force, but also reduce or optimize the NVH problems of the whole vehicle caused by the drive shaft: such as low-speed yaw and high-speed jitter.

[0075] In addition, the needle roller bearing 1 disclosed in the present invention can replace the limiting ring 16 on one side of the traditional needle roller bearing 1 by setting the limiting ring rib 18. Under the premise of ensuring the normal use of the needle roller bearing 1, the number of parts of the needle roller bearing 1 can be reduced, thereby simplifying the actual assembly process.

[0076] The needle roller bearing 1 disclosed in the present invention is mainly designed with an optimized structure of the bearing outer ring 11 .

[0077] The needle roller bearing 1 disclosed in the present invention mainly includes a bearing outer ring 11, a bearing inner ring 15, a needle roller 14 and a limit ring 16; the bearing inner ring 15 and the needle roller 14 can select existing conventional structures, and in the present invention, the bearing outer ring 11 includes an outer ring body; the outer ring body is set as the main structure of the bearing outer ring 11, and an assembly through hole 13 is provided on the outer ring body; the setting of the assembly through hole 13 facilitates the subsequent plug-in assembly of the bearing inner ring 15, the needle roller 14 and the subsequent shaft neck 21.

[0078] At the same time, a limiting ring rib 18 is provided at the edge of the assembly through hole 13 in the present invention; the limiting ring rib 18 and the limiting retaining ring 16 are distributed at both ends of the assembly through hole 13; one end of the limiting ring rib 18 is connected to the inner wall of the assembly through hole 13, and the other end extends to the side close to the central axis of the bearing outer ring 11; the limiting ring rib 18 of the present invention acts as a limiting member, which is convenient for supporting the needle roller 14 and the bearing inner ring 15 on one side during subsequent use. The subsequent setting of the limiting retaining ring 16 can achieve support and limitation of both ends of the needle roller 14 and the bearing inner ring 15, thereby achieving axial limitation of the needle roller 14 and the bearing.

[0079] The outer ring body and the limiting ring rib 18 disclosed in the present invention are an integrated structure. Based on such a configuration, the assembly process of the needle roller bearing 1 can be simplified during subsequent use.

[0080] Furthermore, in the present invention, an assembly recess 12 for assembling the needle roller 14 is provided in the assembly through hole 13; the assembly recess 12 is equivalent to providing a recess structure on the side of the assembly through hole 13, and the assembly recess 12 can be used to store the needle roller 14 structure. The axial limitation of the needle roller 14 is achieved through the assembly recess 12, thereby avoiding friction between the traditional retaining ring and the needle roller 14.

[0081] Furthermore, in the present invention, a snap-in groove 17 for installing a limit retaining ring 16 is provided on the outer ring body; the snap-in groove 17 is arranged at one end of the assembly groove 12 away from the limit ring rib 18; the snap-in groove 17 of the present invention plays a limiting and positioning role; it not only facilitates the assembly and positioning of the limit retaining ring 16 on the outer ring body, but also limits the position of the limit retaining ring 16 by the snap-in groove 17, thereby achieving the end limit of the bearing inner ring 15.

[0082] Furthermore, in the present invention, the outer side surface of the journal 21 is an arc-shaped surface; based on the above configuration, the present invention enables a smooth transition between the outer side surfaces of the journal 21, reduces or avoids the appearance of edges, and reduces the difficulty of assembly between the journal 21 and the needle roller bearing 1.

[0083] Furthermore, in the present invention, the movable joint housing 713 includes a housing 71 body, the interior of the housing 71 body is hollow to form a storage cavity 301, and the inner wall of the storage cavity 301 is provided with a bearing ball track 31; based on such a setting, it is convenient to install and place the tripod bearing assembly 1-1 in the movable joint housing 713; at the same time, in the present invention, the bearing ball track 31 is provided with an avoidance groove 32, and the avoidance groove 32 is used to avoid the shaft neck; the avoidance groove 32 is arranged at the center position of the bearing ball track 31, and the avoidance groove 32 is arranged at the bearing ball track 31 away from the center of the movable joint housing 713; the avoidance groove 32 plays a good avoidance role, avoiding the installation interference between the movable joint housing 713 and the shaft neck 21 during subsequent assembly.

[0084] The tripod-type constant velocity universal joint 101 disclosed in the present invention does not impose rigid requirements on the material and wall thickness of the inner and outer rings of the needle roller bearing 1 .

[0085] As shown in the figure, the tripod type constant velocity universal joint disclosed in the present invention mainly moves the joint housing 713 and the tripod bearing assembly 1-1.

[0086] Assembly sequence: first press the needle bearing 1 onto the journal 21 of the tripod 2, wherein the inner ring 15 of the needle bearing 1 and the journal 21 of the tripod 2 form a spherical pair, and then install the assembled whole into the bearing ball track 31 in the movable joint housing 713.

[0087] The bearing outer ring 11 and the bearing ball track 31 are in two-point contact.

[0088] The needle roller bearing 1 comprises a bearing outer ring 11, a needle roller 14, a bearing inner ring 15 and a fiber retaining ring; the assembly sequence is: first assemble the needle roller 14 into the assembly groove 12 of the bearing outer ring 11, then press the bearing inner ring 15 in, and finally assemble the upper axial limit retaining ring 16 into place for limiting.

[0089] The needle roller bearing 1 disclosed in the present invention reduces the outer ring width and adds a limiting ring rib 18 structure inside the outer ring body, which is equivalent to canceling the axial limiting retaining ring 16 on the lower side of the traditional bearing inner ring 15. The present invention uses the mutual cooperation of the limiting ring rib 18 and the limiting retaining ring 16 to limit the end face of the bearing inner ring 15.

[0090] Compared with the original needle roller bearing 1 design, the assembly process of the needle roller bearing 1 is simplified and the cost is reduced by eliminating the original axial retaining ring on the lower side. More importantly, on the one hand, the friction pair is reduced inside the needle roller bearing 1: for example, the friction pair between the bearing outer ring 11 and the axial retaining ring is reduced, thereby reducing the temperature rise during the operation of the constant velocity universal joint and improving the transmission efficiency. On the other hand, since the friction pair is reduced, when the universal joint has a swing angle, the force of the bearing inner ring 15 on the needle roller 14 and the bearing outer ring 11 is reduced, thereby reducing the axial derived force generated by the sliding of the tripod in the bearing ball track 31 of the movable joint housing 713, thereby reducing the risk of NVH problems such as low-speed yaw and high-speed jitter in the whole vehicle.

[0091] The present invention eliminates the axial retaining ring on the lower side of the needle roller bearing 1, thereby reducing the friction pair inside the bearing, reducing the temperature rise of the universal joint during operation, improving the transmission efficiency of the universal joint, and reducing the axial derivative force, thereby optimizing the NVH problems of the whole vehicle caused by the drive shaft, such as low-speed yaw and high-speed jitter.

[0092] When implementing:

[0093] Assembly sequence: first install all needle rollers 14 into the assembly groove 12 of the bearing outer ring 11, then press the inner ring in, and finally assemble the upper axial retaining ring into place for limiting, then press the assembled three needle roller bearings 1 onto the three journals 21 of the tripod 2, and finally install the assembled tripod bearing assembly 1-1 into the bearing ballway 31 of the movable joint housing 713.

[0094] Furthermore, in the present invention, the tripod-type constant velocity universal joint 101 is connected to the motor 6 via a coupling 10; the coupling 10 can realize torque transmission normally, and also has a good isolation effect to avoid excessive load on the motor 6 when overloaded; in the present invention, the coupling 10 can use a permanent magnet coupling 10.

[0095] Furthermore, in the present invention, the ball cage structure 7 can select the existing structure. The ball cage structure 7 of the present invention mainly includes a ball shell 701, and the ball shell 701 includes a shell 71. The shell 71 is provided with a connecting shaft 72. Here, the main part of the ball shell 701 is an existing structure, which will not be repeated here. The main improvement of the present invention is to optimize the structure of the connecting shaft 72. In the present invention, the ball cage structure 7 is connected to the hub shaft 42 in the hub assembly 4 through the connecting shaft 72; the hub shaft 42 and the connecting shaft 72 are connected through a spline; the present invention arranges a spline on the connecting shaft 72 so that the connecting shaft 72 can be connected following the hub shaft 42. In actual use, the hub shaft 42 is directly connected to the wheel hub. The connecting shaft 72 of the present invention is directly connected to the hub shaft 42. In subsequent use, the rotation of the hub shaft 42 will drive the ball cage structure 7 to rotate, thereby realizing the rotation of the motor 6, thereby realizing the power generation function.

[0096] Similarly, when the wheels are in a snowy or muddy pit, it is very easy for the wheels to slip or spin, making the vehicle unable to drive. At this time, relying solely on the car's own strength to climb out, it is easy for the car to slide sideways or sink deeper and deeper, not only making the entire vehicle unable to drive, but also long-term operation will reduce the service life of the tires; the above-mentioned power generation assembly of the present invention may not perform power generation operations, but may draw power from the vehicle's power supply or vehicle battery pack, so that the motor 6 can be used as a starter, and can supply power to the corresponding wheels, thereby assisting the vehicle to get out of the pit.

[0097] At the same time, a nut assembly 73 is provided at the end of the connecting shaft 72 in the present invention, and the nut includes a nut body, and a limiting flange is provided at the edge of the nut body; in the present invention, the nut assembly 73 mainly plays a locking role, which is beneficial to ensure the stability of the assembly of the connecting shaft 72 on the hub shaft 42. At the same time, a limiting edge groove is provided at the end of the connecting shaft 72 in the present invention; when in use, the limiting flange is bent to make it embedded in the limiting edge groove; the limiting flange of the present invention is bent and embedded in the limiting edge groove, and the limiting flange here acts as a latch structure, which well ensures the stability of the connection of the nut assembly 73 on the connecting shaft 72 and increases the difficulty of disengaging the nut assembly 73 from the connecting shaft 72.

[0098] Furthermore, in the present invention, the nut assembly 73 and the shell 71 in the ball shell 701 are respectively squeezed on the two ends of the hub shaft 42; the nut assembly 73 and the ball shell 701 of the present invention act as limiters and blocking members at both ends of the hub shaft 42, one function is to ensure the stability of the connection between the connecting shaft 72 and the hub shaft 42, and another function is that the ball shell 701 of the present invention also acts as a protective cover to reduce the probability of external debris entering the hub shaft 42 bearing.

[0099] A suspension assembly includes a subframe 5, wherein the subframe 5 is connected to wheel hub assemblies 4 on both sides; at least one side of the wheel hub assembly 4 is connected to the wheel hub power generation assembly 1-9; the present invention provides the wheel hub power generation assembly 1-9; so that a vehicle using the suspension assembly 9 disclosed in the present invention has a wheel kinetic energy recovery device, especially when the vehicle is going downhill, partial recovery of wheel kinetic energy can be achieved, thereby reducing the vehicle's kinetic energy loss.

[0100] In the present invention, the wheel hub assembly 4 includes a wheel hub shaft 43 , a brake disc 41 and a wheel hub bearing 43 , wherein the wheel hub shaft 43 is connected to the brake disc 41 via the wheel hub bearing 43 .

[0101] At the same time, the suspension assembly 9 with the power generation assembly, in addition to the function of recovering energy, the power generation assembly disclosed in the present invention can also serve as a driving end, making it easier for the vehicle with the suspension assembly 9 to escape from a pit.

[0102] During specific connection, one end of the hub power generation assembly 1-9 described in the present invention is connected to the subframe 5, and the other end is connected to the hub assembly 4; in addition, in the present invention, the hub assemblies 4 on both sides of the suspension assembly 9 can be connected to the hub power generation assembly 1-9, or only one side can be connected to the power generation assembly, and the specific selection can be made according to needs.

[0103] Furthermore, the motor 6 in the wheel hub power generation assembly 1-9 described in the present invention is arranged centrally on the subframe 5; based on such a configuration, the dynamic balance of the suspension system can be ensured, and the motor 6 also acts as a counterweight unit to ensure the stable operation of the vehicle.

[0104] In the present invention, the motor 6 shaft of the motor 6 is coaxially arranged with the wheel hub assemblies 4 on both sides of the suspension assembly 9; such an arrangement can realize that one motor 6 is connected to two wheel hub assemblies 4 through two transmission assemblies, thereby reducing the number of motors 6 used. Of course, if the independence of the device is to be ensured, one motor 6 can be selected to be matched with a transmission assembly and connected to a wheel hub assembly 4.

[0105] Furthermore, the motor 6 in the wheel hub power generation assembly 1-9 described in the present invention can be used to generate electricity and / or drive the wheels to rotate; based on the above design, the motor 6 and the wheel hub power generation assembly 1-9 disclosed in the present invention can be used as energy receiving components to facilitate the recovery of wheel kinetic energy, and can also be used as driving components to facilitate the provision of driving force to the corresponding wheels, which can not only facilitate vehicle acceleration, but also assist in realizing the wheel's escape operation.
