[0007] Beneficial effects of the embodiments of the present application: The axle provided by the present application is composed of multiple crossbeams and multiple longitudinal beams, and each crossbeam and each longitudinal beam encloses a frame structure. The frame structure is realized by integrated molding processes such as one-piece casting, one-piece CNC machining, and one-piece powder molding. Compared with the axle connected by welding, the connection points of the one-piece axle are stronger, and the connection points on each crossbeam and each longitudinal beam are more accurate.

[0017] By adopting the above technical solution, the steering gear is installed on the second mounting structure of the front axle mechanism, and the opposite ends of the steering gear are respectively penetrated through the through-hole structures on each longitudinal beam to achieve more stable fixation. In addition, the third side of the second cross beam is connected to the installation method of each longitudinal beam, which can avoid drilling holes on the second cross beam, and the installation process is simpler, thereby improving the installation accuracy of the steering gear on the front axle mechanism.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0038] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] The axles in a vehicle can be divided into front axles and rear axles. The front axles are installed at the front end of the vehicle chassis, and the rear axles are installed at the rear end of the vehicle chassis. They are used for assembly of complete sets of equipment and auxiliary equipment. For example, the front axle is used for installation of steering gear, front balance bar, lower straight arm and lower curved arm, etc., or the rear axle is used for installation of various connecting rods, rear balance bar, tray and shock absorber, etc.

[0040] However, traditional axles are formed by welding various beam structures together. The manufacturing process is relatively simple, but the overall structural strength is relatively low, making it difficult to support the assembly requirements of various equipment.

[0041] In view of this, an embodiment of the present application provides a vehicle axle, including at least two cross beams and at least two longitudinal beams, and at the same time, each cross beam and each longitudinal beam encloses to form a frame structure, and the frame structure is manufactured by an integrated molding method, for example, it can be integrated by sand casting, or it can also be formed by milling on a whole piece of material by a CNC milling center to form an integrated structure, etc. In this way, the material consistency of the connection between each cross beam and each longitudinal beam is higher, and therefore, a vehicle axle with higher structural strength can be obtained.

[0042] Please combine Figures 1 to 4 , the structure of the axle is described below through specific embodiments.

[0043] The vehicle axle of the present application comprises at least two cross beams 10 and at least two longitudinal beams 20. Each cross beam 10 and each longitudinal beam 20 encloses and forms a frame structure, and the frame structure is an integrally formed structure.

[0044] Here, the cross beam 10 and the longitudinal beam 20 are beam structures with different settings, which can be used to limit the direction in which the vehicle body moves forward or backward. For example, the beam structure with the same setting direction as the vehicle's forward or backward direction is the longitudinal beam 20, and the beam structure with a setting direction perpendicular to the vehicle's forward or backward direction is the cross beam 10.

[0045] Meanwhile, the frame structure formed by the cross beams 10 and the longitudinal beams 20 may be similar to a closed structure, for example, two cross beams 10 are arranged at intervals, and two longitudinal beams 20 are also arranged at intervals, and then the cross beams 10 and the longitudinal beams 20 are connected end to end to form a closed frame structure. Of course, on this basis, a certain number of longitudinal beams 20 may be further installed between the two cross beams 10, or a certain number of cross beams 10 may be installed between the two longitudinal beams 20. Alternatively, two frame structures are formed by the cross beams 10 and the longitudinal beams 20, and the two frame structures are connected by a corresponding number of longitudinal beams 20.

[0046] Furthermore, the frame structure is made by an integrated molding process. For example, it can be integrally cast by a sand mold, or formed by milling a whole piece of material by a milling center; or integrally molded by a powder metallurgy process. In this way, the material consistency of the connection between each cross beam 10 and each longitudinal beam 20 is better, and the structural strength is higher.

[0047] The axle provided in the present application is composed of a plurality of cross beams 10 and a plurality of longitudinal beams 20, and each cross beam 10 and each longitudinal beam 20 encloses a frame structure. The frame structure is realized by integrated molding processes such as integral casting, integrated CNC machining, and integrated powder molding. Compared with the axle connected by welding, the connection points of the integrally molded axle have higher strength, and the connection points on each cross beam 10 and each longitudinal beam 20 are more accurate. The integrated frame structure can also reduce the volume, and provide a more accurate connection position for subsequent connection of other equipment.

[0048] Please refer to Figure 1 In some embodiments, there are two cross beams 10, each of which is arranged at an interval, and there are two longitudinal beams 20, each of which has a first end 20a and a second end 20b arranged opposite to the first end 20a. In addition, the two cross beams 10 are respectively defined as a first cross beam and a second cross beam for the convenience of subsequent related statements. The first cross beam has a first side 10a and a second side 10b arranged opposite to the first side 10a. The first end 20a of each longitudinal beam 20 is integrally formed with the first side 10a of the first cross beam, and the second side 10b of the first cross beam is used to connect to the chassis of the vehicle. The opposite ends of the second cross beam are connected to the corresponding longitudinal beams 20, and the second end 20b of each longitudinal beam 20 is used to connect to the anti-collision mechanism.

[0049] It can be understood that the two cross beams 10 and the two longitudinal beams 20 enclose a closed frame structure. Among them, the first end 20a of the longitudinal beam 20 is the end connected to the cross beam 10, and the second end 20b of the longitudinal beam 20 is the end away from the cross beam 10 connected to the first end 20a. For the convenience of explanation, the cross beam 10 connected to the first end 20a of the longitudinal beam 20 is called the first cross beam, and the cross beam 10 close to the second end 20b of the longitudinal beam 20 is called the second cross beam. The first cross beam is used to be integrally formed with the two longitudinal beams 20 to form a relatively stable initial shape structure, and the second cross beam is used to further improve the strength of the overall structure and is connected between the two longitudinal beams 20.

[0050] Furthermore, the first side 10a of the first cross beam is used to be connected to the two longitudinal beams 20, and the second side 10b is opposite to the first side 10a, and the second side 10b is used to be connected to the chassis of the vehicle. Therefore, the relative positional relationship between the first side 10a and the second side 10b is similar to the setting position of the longitudinal beam 20, that is, the first side 10a and the second side 10b are the two sides of the first cross beam that are relatively set along the forward or backward direction of the vehicle.

[0051] For example, corresponding fillets may be provided at the connection points between each longitudinal beam 20 and the first transverse beam to reduce stress concentration at the connection points and improve the connection strength at the connection points.

[0052] At the same time, the second side 10b of the first cross beam is used to connect to the chassis of the vehicle. Here, the length of the first cross beam is adapted to the width of the chassis, and the connection method between the first cross beam and the chassis of the vehicle includes but is not limited to welding, plug-in, clamping, threaded connection, etc.

[0053] Since the second cross beam is used to reinforce the two longitudinal beams 20 , the length of the second cross beam may be shorter than that of the first cross beam.

[0054] The connection method between the second end 20b of the longitudinal beam 20 and the anti-collision mechanism includes but is not limited to welding, plug-in, clamping, threaded connection, etc.

[0055] In this way, the axle has the advantage of simple structure while ensuring high structural strength and high dimensional accuracy.

[0056] Please refer to Figure 1 and Figure 3 In some embodiments, the vehicle axle includes a front axle mechanism 101 and a rear axle mechanism 102 .

[0057] It can be understood that, according to the requirements of the use scenario, the vehicle axle can be divided into a front axle mechanism 101 and a rear axle mechanism 102. Among them, the front axle mechanism 101 is used to be installed at the front end of the chassis of the vehicle, and the rear axle mechanism 102 is used to be installed at the rear end of the chassis of the vehicle.

[0058] Furthermore, the front axle mechanism 101 is mainly used for installing the shock absorbing device and the steering device of the vehicle, while the rear axle mechanism 102 is mainly used for installing the damping device and the connecting mechanism of the vehicle.

[0059] Please refer to Figure 1 and Figure 2 In some embodiments, the axle further includes a mounting shell structure 103 , which is at least partially integrally formed with the longitudinal beam 20 , and the mounting shell structure 103 is used to connect a shock absorbing mechanism or a damping mechanism.

[0060] It can be understood that the mounting shell structure 103 is a shell having an accommodating space therein, so that the weight of the entire axle can be reduced.

[0061] At least a portion of the mounting shell structure 103 is integrally formed with the longitudinal beam 20 , which means that a portion or all of the mounting shell structure 103 is connected to the longitudinal beam 20 through an integral forming process.

[0062] For example, the mounting shell structure 103 may include a shell, and the shell and the longitudinal beam 20 may be integrally cast by sand casting or integrally milled to improve the connection stability between the shell and the longitudinal beam 20 .

[0063] At the same time, the mounting shell structure 103 may also include a connection position provided on the shell, which may be a mounting hole, a mounting boss, a mounting rib, etc., and the connection position is integrally formed on the shell. For example, when the connection position is a solid mounting structure such as a mounting boss, a mounting rib, etc., it can be formed on the shell by an integral casting method, that is, the entire structure of the mounting shell structure 103 is integrally formed on the longitudinal beam 20; or, the connection position can be provided on the shell by welding, threaded connection, riveting, etc., and then a part of the mounting shell structure 103 is integrally formed on the longitudinal beam 20.

[0064] Furthermore, the mounting shell structure 103 has different functions on different axle mechanisms. For example, the mounting shell structure 103 on the front axle mechanism 101 is used for connecting the shock absorbing mechanism of the vehicle, and the mounting shell structure 103 on the rear axle mechanism 102 is used for connecting the damping mechanism of the vehicle.

[0065] In this way, according to the use requirements of the axle, the mounting shell structure 103 arranged on the longitudinal beam 20 thereof can be used to connect with a shock absorbing mechanism or a damping mechanism. For example, when the axle is a front axle mechanism 101, the mounting shell structure 103 is used to connect with the shock absorbing mechanism, and when the axle is a rear axle mechanism 102, the mounting shell structure 103 is used to connect with the damping mechanism. At the same time, the mounting shell structure 103 is integrally formed with the longitudinal beam 20 to improve the connection strength between the mounting shell structure 103 and the longitudinal beam 20.

[0066] Please refer to Figure 1 and Figure 2 In some embodiments, the vehicle axle is a front axle mechanism 101, and a first mounting structure 104 is provided on the mounting shell structure 103, and the first mounting structure 104 is used for mounting an upper fork arm.

[0067] Here, the function of the upper fork arm of the vehicle is to offset the lateral force during the driving process of the vehicle, so as to reduce or eliminate the lateral force exerted on the shock absorbing device of the vehicle. In this way, the shock absorbing device only needs to deal with the up and down shaking of the wheel, and can have better directional stability.

[0068] The first mounting structure 104 may be a mounting column, a mounting rib, a mounting ear or the like, and the connection method between the first mounting structure 104 and the mounting shell structure 103 includes but is not limited to integral molding, welding, threaded connection, riveting or the like.

[0069] In this way, the upper fork arm can be set on the first mounting structure 104 of the front axle mechanism 101. Since the front axle mechanism 101 is formed by integral casting, the installation position accuracy of the first mounting structure 104 on the front axle mechanism 101 is higher, thereby improving the installation accuracy of the upper fork arm on the front axle mechanism 101.

[0070] For example, please refer to Figure 1 The first mounting structure 104 is two mounting ears that are integrally formed on the mounting shell structure 103 and are spaced apart from each other. The upper fork arm is connected to the two mounting ears by a hinged manner.

[0071] Please refer to Figure 1 and Figure 2 In some embodiments, the second cross beam has a third side 10c, the third side 10c of the second cross beam is connected to each longitudinal beam 20, a second mounting structure 105 is provided on the third side 10c, the second mounting structure 105 is used for the installation of the steering gear, and both longitudinal beams 20 are provided with a through hole structure 106 for the steering gear to pass through.

[0072] Here, referring to the previous description, the cross beam 10 close to the second end 20 b is called a second cross beam. The second cross beam is far away from the first end 20 a of the longitudinal beam 20 and close to the second end 20 b of the longitudinal beam 20 , and serves to enhance the structural strength of each longitudinal beam 20 .

[0073] And, the third side 10c of the second cross beam refers to a side of the second cross beam used for connecting with each longitudinal beam 20, and the third side 10c can be directly connected with each longitudinal beam, and can also be indirectly connected with each longitudinal beam.

[0074] The steering gear is used to achieve vehicle steering. The second mounting structure 105 can be a mounting column, a mounting rib, a mounting ear, etc., and the connection method between the second mounting structure 105 and the crossbeam 10 includes but is not limited to integral molding, welding, threaded connection, riveting, etc.

[0075] At the same time, in order to further obtain installation space and limit the space of the steering gear, a through hole structure 106 is opened on the corresponding longitudinal beam 20 for the steering gear to pass through and install. In addition, the third side 10c of the second cross beam is connected to each longitudinal beam 20, and each longitudinal beam 20 and the third side 10c of the second cross beam jointly enclose a space for the steering gear to be installed, which can avoid opening a hole on the second cross beam. The steering gear is also installed at the second installation structure 105 on the third side 10c, and the entire installation process is simpler and more efficient.

[0076] In this way, the steering gear is installed on the second mounting structure 105 of the front axle mechanism 101, and the opposite ends of the steering gear are respectively penetrated through the through-hole structures 106 on each longitudinal beam 20 to achieve more stable fixation. In this way, since the front axle mechanism 101 is formed by one-piece casting, the installation position accuracy of the second mounting structure 105 on the front axle mechanism 101 is higher, thereby improving the installation accuracy of the steering gear on the front axle mechanism 101.

[0077] Please refer to Figure 2 In some embodiments, a third mounting structure 107 is provided on the side of the longitudinal beam 20 that is opposite to the mounting shell structure 103, and the third mounting structure 107 is used for mounting the lower straight arm;

[0078] And / or, a fourth mounting structure 108 is provided on a side of the longitudinal beam 20 that is opposite to the mounting shell structure 103 , and the fourth mounting structure 108 is used for mounting the lower bent arm.

[0079] It can be understood that both the lower straight arm and the lower curved arm are part of the vehicle suspension system, and they can support the weight of the vehicle body, cushion the impact of the road, control the movement of the wheels, and adjust the suspension geometry parameters.

[0080] Taking the setting position of the mounting shell structure 103 on the longitudinal beam 20 as a reference system, the third mounting structure 107 and the fourth mounting structure 108 are both arranged opposite to the mounting shell structure 103, that is, the mounting shell structure 103 and the third mounting structure 107 and the fourth mounting structure 108 are respectively located on the opposite sides of the longitudinal beam 20. In particular, when the longitudinal beam 20 has a front and a back side for installation, it can be defined that the mounting shell structure 103 is on the front side of the longitudinal beam 20, and the third mounting structure 107 and the fourth mounting structure 108 are on the back side of the longitudinal beam 20.

[0081] The third mounting structure 107 may be a mounting column, a mounting rib, a mounting ear or the like, and the connection method between the third mounting structure 107 and the longitudinal beam 20 includes but is not limited to integral molding, welding, threaded connection, riveting or the like.

[0082] For example, the third mounting structure 107 is a mounting ear integrally formed on the longitudinal beam 20 , and the mounting ear has two free ends spaced apart from each other, and mounting holes are respectively provided on the two free ends to fix the lower straight arm between the two free ends.

[0083] The fourth mounting structure 108 may be a mounting column, a mounting rib, a mounting ear, or the like, and the connection method between the fourth mounting structure 108 and the longitudinal beam 20 includes but is not limited to integral molding, welding, threaded connection, riveting, or the like.

[0084] For example, the fourth mounting structure 108 is a mounting column integrally formed on the longitudinal beam 20 , and a mounting hole is provided on the mounting column for connecting the lower bent arm to the mounting column.

[0085] In this way, the lower straight arm is arranged on the third mounting structure 107 of the front axle mechanism 101, and the lower bent arm is arranged on the fourth mounting structure 108 of the front axle mechanism 101. Since the front axle mechanism 101 is formed by integral casting, the installation position accuracy of the third mounting structure 107 and the fourth mounting structure 108 on the front axle mechanism 101 is higher, thereby improving the installation accuracy of the lower straight arm and the lower bent arm on the front axle mechanism 101.

[0086] Of course, in other embodiments, multiple sets of fourth mounting structures 108 may be provided for connection with other rod-shaped structures, such as a balance rod mechanism.

[0087] Please refer to Figure 3 and Figure 4 In some embodiments, the vehicle axle is a rear axle mechanism 102, and a fifth mounting structure 109 is provided on one side of the longitudinal beam 20 on which the mounting shell structure 103 is provided. The fifth mounting structure 109 is used for mounting the connecting rod mechanism.

[0088] It can be understood that the connecting rod mechanism includes a plurality of connecting rods connected in a linked manner, and the connecting rods are used to provide support for the automobile suspension device. The number of connecting rods can be increased or decreased according to actual use requirements.

[0089] The fifth mounting structure 109 may be a mounting column, a mounting rib, a mounting ear or the like, and the connection method between the fifth mounting structure 109 and the longitudinal beam 20 includes but is not limited to integral molding, welding, threaded connection, riveting or the like.

[0090] For example, the fifth mounting structure 109 is two mounting ears that are integrally formed on the longitudinal beam 20 and spaced apart from each other, and one end of the connecting rod mechanism is hinged to the two mounting ears.

[0091] In this way, the fifth mounting structure 109 and the mounting shell structure 103 are located on the same side of the longitudinal beam 20, and part of the connecting rod mechanism is arranged on the fifth mounting structure 109 of the longitudinal beam 20 of the rear axle mechanism 102. Since the rear axle mechanism 102 is formed by one-piece casting, the installation position accuracy of the fifth mounting structure 109 on the rear axle mechanism 102 is higher, thereby improving the installation accuracy of the connecting rod mechanism on the rear axle mechanism 102.

[0092] Please refer to Figure 3 and Figure 4 In some embodiments, a sixth mounting structure 110 is provided on a side of the longitudinal beam 20 that is opposite to the mounting shell structure 103 , and the sixth mounting structure 110 is used for mounting the connecting rod mechanism.

[0093] Similarly, taking the setting position of the mounting shell structure 103 on the longitudinal beam 20 as a reference system, the fifth mounting structure 109 and the mounting shell structure 103 are located on the same side of the longitudinal beam 20, and the sixth mounting structure 110 is arranged opposite to the mounting shell structure 103 and is located on the other side of the longitudinal beam 20. When the longitudinal beam 20 has a front and back side for installation, it can be defined that the mounting shell structure 103 and the fifth mounting structure 109 are on the front side of the longitudinal beam 20, and the sixth mounting structure 110 is on the back side of the longitudinal beam 20.

[0094] The connecting rod mechanism includes a plurality of connecting rods connected in a linked manner. The connecting rods are used to provide support for the automobile suspension device. The number of connecting rods can be increased or decreased according to actual use requirements.

[0095] The sixth mounting structure 110 may be a mounting column, a mounting rib, a mounting ear or the like, and the connection method between the sixth mounting structure 110 and the longitudinal beam 20 includes but is not limited to integral molding, welding, threaded connection, riveting or the like.

[0096] For example, the sixth mounting structure 110 is two mounting ears that are integrally formed on the longitudinal beam 20 and spaced apart from each other, and one end of the connecting rod is hinged to the two mounting ears.

[0097] In this way, the sixth mounting structure 110 and the mounting shell structure 103 are located on opposite sides of the longitudinal beam 20, and the remaining connecting rod mechanisms are arranged on the sixth mounting structure 110 of the longitudinal beam 20 of the rear axle mechanism 102. Since the rear axle mechanism 102 is formed by one-piece casting, the installation position accuracy of the sixth mounting structure 110 on the rear axle mechanism 102 is higher, thereby improving the installation accuracy of the connecting rod mechanism on the rear axle mechanism 102.

[0098] Of course, in other embodiments, multiple groups of sixth mounting structures 110 may be provided to provide other rod-shaped mechanism structures, such as a balance rod mechanism.

[0099] In a second aspect, the present application also provides a vehicle, comprising the above-mentioned axle and a shock absorbing mechanism, a damping mechanism, an upper fork arm, a steering gear, a lower straight arm, a lower curved arm and a connecting rod mechanism connected to the axle.

[0100] It can be understood that the beneficial effects of the second aspect mentioned above can be found in the relevant description of the first aspect mentioned above, and will not be repeated here.

[0101] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
