[0027] Reference below Figure 1-Figure 4 The following describes a suspension bracket 100 according to an embodiment of the first aspect of the present invention.

[0028] like Figure 1-Figure 4 As shown, the suspension bracket 100 according to the embodiment of the first aspect of the present invention includes: two supporting parts 10 and two extending parts 20.

[0029] Specifically, the two support parts 10 are arranged along a first direction (eg, Figure 1 The two extension portions 20 are respectively arranged on the two support portions 10 in the second direction (for example, Figure 1 On the same side of the support portion 10 (the front-to-back direction in the figure), each extension portion 20 extends obliquely in a direction away from the support portion 10 in the second direction.

[0030] For example, in Figure 1-Figure 4In the example shown, two support portions 10 are positioned opposite each other along the thickness direction of the support portion 10. An extension portion 20 is provided at one end of each support portion 10 in the longitudinal direction. The extension portion 20 is located on one side of the width direction of the support portion 10 and extends upwardly and obliquely away from the support portion 10. A mounting hole 201 is formed at the end of each extension portion 20 away from the support portion 10. During installation, fasteners, such as bolts, are inserted through the mounting holes 201 to connect to the bottom of the cab. The other end of the support portion 10 in the longitudinal direction is connected to the longitudinal rail of the vehicle frame, thereby installing the suspension support between the cab and the longitudinal rail, thereby better supporting the cab.

[0031] Each support portion 10 includes a first support segment 103 and a second support segment 104 connected to each other, and the first support segment 103 and the second support segment 104 are connected along the third direction (for example, Figure 1 The first supporting segment 103 protrudes from the second supporting segment 104 in the first direction, and the first direction, the second direction and the third direction are orthogonal to each other.

[0032] Specifically, within the projection plane of the suspension bracket 100 along the second direction, the first support segment 103 and the second support segment 104 lie within two planes. That is, in the first direction, the distance between the two first support segments 103 of the two support portions 10 is greater than the distance between the two second support segments 104 of the two support portions 10. Part of the support portion 10 is recessed toward the opposing support portion 10 along the first direction to form the second support segment 104, while the remaining portion of the support portion 10 constitutes the first support portion 10. This creates a bending structure at the junction of the first support segment 103 and the second support segment 104. When the front of the cab is impacted, the suspension bracket 100 can be effectively bent under the guidance of the bending mechanism, thereby increasing the rearward displacement of the cab and reducing the impact energy absorbed by the cab. This, in turn, increases the survivability space (compared to existing vehicle body mounts, the survivability space can be increased by more than 15%), thereby improving the passive safety of the cab.

[0033] It should be noted that the first direction may be the thickness direction of the support portion 10 , the second direction may be the width direction of the support portion 10 , and the third direction may be the length direction of the support portion 10 , but the present invention is not limited thereto.

[0034] Optionally, the connection between the first support segment 103 and the second support segment 104 may be rounded to achieve a smooth transition between the first support segment 103 and the second support segment 104 .

[0035] According to the suspension bracket 100 of the embodiment of the present invention, by making the first support section 103 protrude from the second support section 104 in the first direction, a bending structure is formed at the connection between the first support section 103 and the second support section 104. When the front of the cab is hit, the suspension bracket 100 can be effectively bent under the guidance of the above-mentioned bending mechanism, thereby increasing the rearward displacement of the cab and reducing the impact energy absorbed by the cab, thereby increasing the living space and improving the passive safety of the cab.

[0036] According to some embodiments of the present invention, the width of each support portion 10 in the second direction gradually increases in the third direction away from the extension portion 20. That is, each support portion 10 has a smaller width at one end in the longitudinal direction and a larger width at the other end in the longitudinal direction. During installation, the smaller end of the support portion 10 is connected to the bottom of the cab, and the larger end of the support portion 10 is connected to the longitudinal rail of the vehicle frame.

[0037] Among them, since the stress of the suspension bracket 100 is mainly concentrated on the end of the suspension bracket 100 connected to the longitudinal beam when the front of the cab is hit, by adopting finite element simulation analysis of the whole vehicle, the width of one end of each support part 10 and the longitudinal beam of the frame is set to be larger, which can improve the connection strength between the suspension bracket 100 and the longitudinal beam and make the structure of the suspension bracket 100 more stable.

[0038] According to some embodiments of the present invention, each support portion 10 is provided with a bending portion 30 on the other side of the second direction, the bending portion 30 is bent along the first direction toward the opposite support portion 10, and the bending portion 30 extends along the circumference of the support portion 10. Figure 1 and Figure 2 The bent portion 30 is provided on one side of the support portion 10 in the thickness direction and extends toward the opposite support portion 10. The bent portion 30 is also located on one side of the support portion 10 in the width direction. One end of the bent portion 30 extends to one end of the support portion 10 in the third direction, and the other end of the bent portion 30 extends to the other end of the support portion 10 in the third direction. Even if the direction of the bent portion 30 is consistent with that of the support portion 10, the bent portion 30 can bend along with the support portion 10 when the front of the cab is hit, ensuring that there is more survival space in the cab.

[0039] In some optional embodiments, the shape of the bent portion 30 is arc-shaped or wavy. Figure 1 what Figure 2 As shown, the shape of the bending portion 30 is wavy, that is, the trough of the bending portion 30 in the second direction is opposite to the connection between the first support section 103 and the second support section 104, which is conducive to effective bending of the suspension bracket 100 when subjected to force.

[0040] According to some specific embodiments of the present invention, the two bending portions 30 are respectively a bending portion 301 and a second bending portion 302. On the projection surface in the second direction, the first bending portion 301 blocks at least a portion of the second bending portion 302. The first bending portion 301 can block the entire second bending portion 302 on the projection surface in the second direction (not shown); or the first bending portion 301 can block a portion of the second bending portion 302 on the projection surface in the second direction (not shown). Figure 1 and Figure 2 As shown). With such an arrangement, the contact area of ​​the two bent portions 30 can be increased, thereby ensuring the connection reliability of the two bent portions 30, and the structure of the suspension bracket 100 is simple and easy to process.

[0041] According to some embodiments of the present invention, each bending portion 30 is formed with a notch 303 on a side away from the support portion 10 in the first direction, and the two notches 303 of the two bending portions 30 are opposite to each other in the first direction and jointly define a groove. Figure 1 、 Figure 2 and Figure 4 In the example, one side surface in the width direction of each bent portion 30 is recessed toward the support portion 10 to form a notch 303. In the first direction, the notch 303 is opposite the connection between the first support segment 103 and the second support segment 104. This reduces the weight of the suspension bracket 100 (for example, the weight of the existing vehicle body suspension is 8.84 kg, while the suspension bracket 100 of the present application weighs 7.32 kg, a 14% reduction), facilitating a lightweight design of the suspension assembly. Furthermore, it further weakens the structural strength of the connection between the first support segment 103 and the second support segment 104, facilitating effective bending of the suspension bracket 100 when subjected to force.

[0042] According to some embodiments of the present invention, a portion of the surface of the first support section 103 on one side in the third direction is recessed toward the center of the support portion 10 to form at least one recessed portion 101, and the extension portion 20 is connected to the corresponding second support section 104. Figure 1-Figure 3 As shown, the recessed portion 101 and the extension portion 20 are respectively provided on both sides of the support portion 10 in the third direction. There are two recessed portions 101, which are spaced apart along the second direction. One of the two recessed portions 101 is located in the middle of the first support segment 103, and the other end of the two recessed portions 101 is located at the end of the first support segment 103. Thus, while ensuring the structural strength of the end of the suspension bracket 100 connected to the longitudinal beam, the weight of the suspension bracket 100 can be further reduced, thereby reducing costs.

[0043] According to some embodiments of the present invention, at least one of the two support portions 10 is formed with a through hole 102, and the through hole 102 is located between the recessed portion 101 and the extension portion 20. In particular, both support portions 10 are formed with a through hole 102 (not shown); or, one of the two support portions 10 is formed with a through hole 102 (e.g., Figure 1 shown).

[0044] like Figure 1 As shown, a through hole 102 is formed on one of the two support parts 10. The through hole 102 is located between the connection between the first support section 103 and the second support section 104 and the recessed portion 101. A nut 40 is provided on the other of the two support parts 10. The nut 40 and the through hole 102 facilitate installation of the nut 40 through the through hole 102. This arrangement can further reduce the weight of the suspension bracket 100 and further reduce costs.

[0045] The suspension assembly (not shown) according to the embodiment of the second aspect of the present invention includes the suspension bracket 100 according to the embodiment of the first aspect of the present invention.

[0046] According to the suspension assembly of the embodiment of the present invention, by adopting the above-mentioned suspension bracket 100, the cost of the suspension assembly can be reduced, which is conducive to the lightweight design of the suspension assembly.

[0047] A vehicle (not shown) according to an embodiment of the third aspect of the present invention comprises a suspension assembly according to an embodiment of the second aspect of the present invention.

[0048] According to the vehicle of the embodiment of the present invention, by adopting the above-mentioned suspension assembly, it is possible to reduce the weight of the entire vehicle, reduce costs, and improve time competitiveness.
