[0033] Reference below Figure 1-Figure 11 A suspension connection structure according to an embodiment of the present utility model is described.

[0034] In the related art, a stud is usually provided on the inner core, and the stud passes through the suspension bracket and is screwed with a nut to achieve the connection between the suspension bracket and the suspension. Long-term driving of the vehicle under harsh working conditions will lead to fatigue failure of the suspension structure.

[0035] Therefore, the utility model proposes a new suspension connection structure.

[0036] like Figure 1-Figure 4 As shown, the suspension connection structure includes: a suspension bracket 1 , an inner core 201 and a reinforcement member 202 .

[0037] The suspension bracket 1 is provided with a receiving space 101, and the inner core 201 is provided with a connecting end 2011, which is inserted into the receiving space 101. In addition, a connecting hole 2021 is formed in the connecting end 2011 of the reinforcement member 202, and the suspension bracket 1 is connected to the connecting end 2011 through the connecting hole 2021 provided by the connecting member 3.

[0038] The suspension connection structure of this embodiment improves the connection strength between the suspension bracket 1 and the suspension 2 by embedding the reinforcement 202 in the connection end 2011 and allowing the suspension bracket 1 to pass through the connection hole 2021 on the reinforcement 202 via the connection member 3 and be fixedly connected to the connection end 2011. In addition, the powertrain is installed on the suspension 2 of the vehicle body through the suspension bracket 1, so that the bottom of the connection hole 2021 is subjected to the pressure of the connection member 3, and the reinforcement 202 can improve the local surface compression strength, thereby extending the fatigue service life of the suspension connection structure.

[0039] In addition, since there is generally a large operating space in the length direction of the vehicle, the reinforcement member 202 can be embedded in the connection end 2011 along the length direction of the vehicle, which can facilitate the connection between the inner core 201 and the suspension bracket 1. Of course, the reinforcement member 202 can also be embedded in the connection end 2011 along the width direction of the vehicle, and there is no specific limitation on this.

[0040] In addition, by providing the accommodation space 101 and inserting the connecting end 2011 into the accommodation space 101, it is possible to prevent external impurities from contaminating the connecting member 3, thereby facilitating subsequent disassembly and maintenance.

[0041] In the embodiment disclosed in the present utility model, the connection hole 2021 is a threaded hole, the connection member 3 is a bolt, and the connection member 3 is threadedly connected to the connection hole 2021 .

[0042] According to a further embodiment of the utility model, the suspension bracket 1 is provided with a plurality of mounting holes 107, the mounting holes 107 are arranged at intervals from the accommodation space 101, and the mounting holes 107 are penetrated by fasteners for fixed connection with the engine assembly. Specifically, the plurality of mounting holes 107 are arranged along the height direction and / or the length direction and / or the width direction of the vehicle to ensure reliable connection with the engine assembly.

[0043] According to a further embodiment of the present utility model, a plurality of through holes 108 are provided on the suspension bracket 1 , and the through holes 108 are spaced apart from the accommodating space 101 for arranging wiring harnesses and / or pipelines.

[0044] Therefore, according to the suspension connection structure of the utility model, by embedding the reinforcement member 202 in the connection end 2011, the suspension bracket 1 is fixedly connected to the connection end 2011 through the connection member 3 through the connection hole 2021 on the reinforcement member 202, thereby improving the connection strength between the suspension bracket 1 and the suspension 2, thereby improving the fatigue service life of the suspension connection structure. In addition, by embedding the reinforcement member 202 in the connection end 2011, the connection between the inner core 201 and the suspension bracket 1 can be facilitated, and it is convenient for later disassembly and maintenance.

[0045] Furthermore, a tooth-shaped structure 2022 is provided on the outer side of the reinforcement member 202 , and the tooth-shaped structure 2022 is connected and matched with the connection end 2011 .

[0046] refer to Figure 5 and Figure 6 As shown, a circle of tooth-shaped structure 2022 is provided around the outer side surface of the reinforcement member 202, which increases the contact area with the connection end 2011 and improves the friction between the reinforcement member 202 and the connection end 2011, thereby effectively improving the connection strength.

[0047] In an embodiment disclosed in the present invention, the tooth-shaped structure 2022 is teeth of the same size, which is convenient to manufacture.

[0048] Exemplarily, the reinforcement member 202 is a cylindrical structure.

[0049] Alternatively, the reinforcement member 202 may also be a polygonal structure, but is not limited thereto.

[0050] Furthermore, the connection end 2011 is provided with at least one stepped through hole 2012 , the reinforcement member 202 is embedded in the stepped through hole 2012 , and one end of the reinforcement member 202 abuts against the step surface of the stepped through hole 2012 .

In the embodiment disclosed in the utility model, a stepped through hole 2012 is provided at the connection end 2011, so that a reinforcement member 202 is embedded in the connection end 2011.

[0056] Further, the strength and / or hardness of the first metal material piece is higher than the strength and / or hardness of the second metal material piece.

[0057] Thus, the strength and / or hardness of the reinforcing member 202 is higher than that of the inner core 201 , so as to improve the strength and / or hardness of the connecting end 2011 of the inner core 201 , thereby improving the connection strength between the suspension bracket 1 and the suspension 2 .

[0058] Furthermore, the reinforcement member 202 and the inner core 201 are an integrally formed structural member.

In addition, the circular tube portion 2042 is matched with the through hole 2031 of the inner core 201 and the outer tube 203, which can limit the radial movement of the inner core 201 and ensure that the inner core 201 moves up and down in the height direction. In addition, it plays a protective role for both the inner core 201 and the outer tube 203.

[0067] Furthermore, a step structure 2043 is formed on the inner wall of the circular tube portion 2042.
