The longitudinal beam connecting bracket 110 is used to connect with the longitudinal beam of the vehicle body, and the suspension shell 112 is installed on the front subframe 1065. The longitudinal beam connecting bracket 110 extends toward the outside of the suspension shell 112.

[0050] In the embodiment of the present invention, the longitudinal beam connecting bracket 110 is made of cast aluminum, which has low development difficulty and low cost, can be quickly mass-produced through molds, and has high anti-corrosion performance. Compared with traditional DC01 or SAPH440 materials, the anti-corrosion performance is effectively improved.

[0051] In the embodiment of the present invention, the suspension device is optimized into two parts, including a suspension housing 112 and a longitudinal beam connection bracket 110, and the suspension housing 112 and the longitudinal beam connection bracket 110 are not connected by bolts, and the longitudinal beam connection bracket 110 is directly press-fitted on the T-shaped mounting structure on the suspension housing 112. Compared with the solution of bolt connection in the prior art, the overall stability of the bracket is better, the passive lateral dynamic stiffness of the suspension is higher, and the vibration isolation performance and universality of the suspension are higher.

[0052] like Figures 13 to 16 As shown, the mounting structure includes a first connection portion 113 connected to the suspension housing 112 and a clamping portion connected to the first connection portion 113, the clamping portion is connected to the longitudinal beam connection bracket 110 and is embedded in the clamping slot 118, the clamping portion and the longitudinal beam connection bracket 110 are tightly matched, the shape of the clamping portion matches the shape of the clamping slot 118, and the clamping portion is a T-shaped structure. The clamping portion includes a second connection portion 114 connected to the first connection portion 113 and a third connection portion 115 connected to the second connection portion 114, the second connection portion 114 is located between the first connection portion 113 and the third connection portion 115, the width of the second connection portion 114 is smaller than the width of the third connection portion 115, the width directions of the first connection portion 113 and the second connection portion 114 are parallel to the width direction of the third connection portion 115, and the width directions of the first connection portion 113, the second connection portion 114 and the third connection portion 115 are parallel to the Z direction.

The length directions of the first connection part 113, the second connection part 114 and the third connection part 115 are parallel and the lengths of the first connection part 113, the second connection part 114 and the third connection part 115 are the same. The widths of the first connection part 113, the second connection part 114 and the third connection part 115 are the same. The length directions of the first connection part 113, the second connection part 114 and the third connection part 115 are parallel and perpendicular to their respective width directions.

[0058] like Figures 13 to 16As shown, the suspension housing 112 includes a base 121 and a protrusion disposed on the base 121. The base 121 is used to connect to the front subframe 1065. The protrusion is fixedly connected to the outer wall of the base 121, and the protrusion extends toward the outside of the base 121. The protrusion is located at the upper end of the base 121. The mounting structure is fixedly connected to the protrusion, and the protrusion is located between the first connecting portion 113 and the base 121. The protrusion is a trapezoidal block structure, and the outer surface of the protrusion includes a first surface 119 and a second surface 120. The first surface 119 and the second surface 120 are both provided with two, the two first surfaces 119 are distributed in a V shape, and the two second surfaces 120 are distributed in a V shape. The two ends of the two first surfaces 119 are connected to the two ends of the two second surfaces 120 respectively. The two first surfaces 119 are arranged in sequence along the height direction (Z direction) of the base 121, the first end of the first surface 119 is fixedly connected to the outer wall surface of the base 121, the second end of the first surface 119 is fixedly connected to a side edge of the first connecting portion 113, the distance between the first ends of the two first surfaces 119 is greater than the distance between the second ends of the two first surfaces 119, and the second ends of the two first surfaces 119 are fixedly connected to the upper and lower sides of the first connecting portion 113, respectively. The two second surfaces 120 are arranged in sequence along the length direction of the base 121 (the length direction of the base 121 is parallel to the length direction of the first connecting portion 113), the first end of the second surface 120 is fixedly connected to the outer wall surface of the base 121, the second end of the second surface 120 is fixedly connected to a side edge of the first connecting portion 113, the distance between the first ends of the two second surfaces 120 is greater than the distance between the second ends of the two second surfaces 120, the second ends of the two second surfaces 120 are respectively fixedly connected to the other two side edges of the first connecting portion 113, the first connecting portion 113 is a rectangular structure with four side edges, the two first surfaces 119 and the two second surfaces 120 are respectively connected to a side edge of the first connecting portion 113.

[0059] The protrusions of the trapezoidal block structure are connected to the mounting structure, providing additional support and stability, especially when subjected to dynamic loads. The V-shaped distribution of the first surface 119 and the second surface 120 and their fixed connection with the base 121 and the first connecting portion 113 form a solid triangular support structure, which enhances the overall rigidity and durability, helps to disperse and absorb vibration energy, and further improves the vibration isolation effect.

[0060] like Figures 13 to 16As shown, the suspension housing 112 also includes a reinforcing rib 111 fixedly arranged on the base 121. A plurality of reinforcing ribs 111 are provided, and all reinforcing ribs 111 are arranged in sequence along the width direction of the base 121. The width direction of the base 121 is parallel to the thickness direction of the first connection part 113 and the third connection part 115, and the thickness direction of the third connection part 115 is perpendicular to its length direction and width direction. The provision of the reinforcing rib 111 significantly improves the structural strength and rigidity of the suspension housing, especially in the base 121 area. This helps to resist stress caused by factors such as powertrain vibration and road unevenness, which helps to reduce deformation caused by vibration, thereby improving the performance of the suspension system.

[0061] The third front suspension assembly 1073 of the above structure has the following advantages:

[0062] 1. Improve the dynamic stiffness of the bracket and optimize the NVH performance of the vehicle;

[0063] 2. Cancel the bolt connection, simplify the assembly process, reduce costs, and the installation structure will not protrude above the longitudinal beam connection bracket, which can reduce the occupied Z-direction space;

[0064] 3. It only involves the suspension shell, with a small impact range, short development cycle and high degree of commonality, effectively improving the three levels of suspension.

[0065] The embodiment of the present invention further provides an assembly method of a third front suspension assembly 1073, comprising the following steps:

[0066] S1. Provide a suspension housing 112 and a longitudinal beam connecting bracket 110, wherein a mounting structure is provided on the suspension housing 112;

[0067] S2. Press-fit the longitudinal beam connecting bracket 110 onto the mounting structure.

[0068] In the above step S2, the longitudinal beam connecting bracket 110 is pressed onto the mounting structure provided on the suspension shell 112. The mounting structure and the suspension shell 112 are integrally formed, and the mounting structure is embedded in the slot 118 on the longitudinal beam connecting bracket 110. The two are tightly matched, and the assembly process is simple.
