[0002] Generally, large vehicles such as new energy commercial vehicles adopt a non-independent suspension structure, and use a thrust rod to guide and transmit the rod force.

[0003] In the prior art, during the assembly of such vehicles, the two ends of the longitudinal thrust rod need to be respectively connected to the front axle end and the frame end. The longitudinal thrust rod includes a first thrust rod and a second thrust rod. However, since the ball joints at the ends of the first thrust rod and the second thrust rod are rubber elastic parts, they will have a certain deformation and rotation under the action of gravity, resulting in that after one end of the first thrust rod and the second thrust rod are both assembled to the frame end or the front axle end, when the other ends of the first thrust rod and the second thrust rod are assembled together with the front axle end or the frame end, the distance between the first thrust rod and the second thrust rod cannot be controlled, the assembly difficulty is large, the efficiency is low, and there are also safety hazards in manual assembly.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without creative efforts shall fall within the protection scope of the present invention.

[0068] The following will, with reference to the accompanying drawings, elaborate on the technical solutions provided by each embodiment of this specification in detail.

[0069] Figure 1 It is a schematic structural diagram of a longitudinal thrust rod assembly limiting structure in this specification. As Figure 1 shown, this longitudinal thrust rod assembly limiting structure includes a first limiting member 1, a second limiting member 2, and a bolt connecting member 3.

[0070] Preferably, this longitudinal thrust rod includes a first thrust rod 51 and a second thrust rod 52.

[0074] Figure 2 It is a schematic structural diagram of the first limiting member 1 provided by an embodiment of this specification. As Figure 2 shown, the first limiting member 1 includes a first arc end 11 and a first connecting plate 12, and a plurality of first serrated members 13 are arranged on the first surface of the first connecting plate 12. The first connecting plate 12 is also configured with a connecting through hole 14.

[0075] Preferably, the second limiting member 2 is configured with a second arc end 21 and a second connecting plate 22.

[0076] Preferably, the inner wall of the second arc end 21 can be in close contact with the second thrust rod 52.

[0077] It should be noted that the inner wall of the first arc end 11 can also be in close contact with the second thrust rod 52, and the inner wall of the second arc end 21 can also be in close contact with the first thrust rod 51. This specification does not make any restrictions here.

[0078] Preferably, the second connecting plate 22 is also a plate-like structure, and a plurality of second serrated members 23 are arranged on the second surface of the second connecting plate 22. The second connecting plate 22 is also configured with a connecting through slot.

[0079] Among them, the first serrated member 13 is adapted to the second serrated member 23. The sizes of the bolt connecting member 3, the connecting through hole 14, and the connecting through groove are adapted to each other, and the bolt connecting member 3 can pass through the connecting through hole 14 and the connecting through groove to connect and fix the first connecting plate 12 and the second connecting plate 22. It should be emphasized that when the first connecting plate 12 and the second connecting plate 22 are connected and fixed by the bolt connecting member 3, the first surface of the first connecting plate 12 is in close contact with the second surface of the second connecting plate 22, and the plurality of first serrated members 13 and the plurality of second serrated members 23 mesh with each other.

[0080] It should be emphasized that the first surface and the second surface have no special meaning. The first surface of the first connecting plate 12 and the second surface of the second connecting plate 22 are only different in naming and have no other meaning. The position of the first surface on the first connecting plate 12 can be the same as or opposite to the position of the second surface on the second connecting plate 22, and this specification does not limit this here.

[0081] Preferably, the first connecting plate 12 can be connected to the second connecting plate 22 by the bolt connecting member 3.

[0082] Preferably, when the first connecting plate 12 is connected to the second connecting plate 22, the opening direction of the arc structure of the first arc end 11 is the same as the opening direction of the arc structure of the second arc end 21.

[0083] Preferably, when the first connecting plate 12 is connected to the second connecting plate 22, the opening direction of the arc structure of the first arc end 11 is opposite to the opening direction of the arc structure of the second arc end 21.

[0084] Figure 3 And Figure 4 Both are schematic diagrams of the connection structure between the first limiting member 1 and the second limiting member 2 provided by an embodiment of this specification. As Figure 3 shown, the opening direction of the arc structure of the first arc end 11 is the same as the opening direction of the arc structure of the second arc end 21. As Figure 4 shown, the opening direction of the arc structure of the first arc end 11 is opposite to the opening direction of the arc structure of the second arc end 21.

[0085] Preferably, when the inner wall of the first arc end 11 is in close contact with the first thrust rod 51 and the inner wall of the second arc end 21 is in close contact with the second thrust rod 52, the longitudinal thrust rod assembly limiting structure can limit the relative movement of the first thrust rod 51 and the second thrust rod 52.

[0086] Specifically, the longitudinal thrust rod assembly limiting structure can limit the relative movement of the first thrust rod 51 and the second thrust rod 52 in the direction of approaching or separating from each other.

[0087] Figure 5 The following is a schematic diagram of the application of the longitudinal thrust rod assembly limiting structure provided in an embodiment of this specification. As Figure 5 shown, the first arc end 11 and the second arc end 21 are respectively in close contact with the first thrust rod 51 and the second thrust rod 52 of the longitudinal thrust rod. The longitudinal thrust rod assembly limiting structure fixes the relative distance between the first thrust rod 51 and the second thrust rod 52, making it difficult for the first thrust rod 51 and the second thrust rod 52 to move relatively in the direction of approaching or separating from each other.

[0088] According to the above embodiment, the longitudinal thrust rod assembly limiting structure includes a first limiting member 1, a second limiting member 2, and a bolt connecting member 3. Among them, the first limiting member 1 is configured with a first arc end 11 and a first connecting plate 12. The inner wall of the first arc end 11 can be in close contact with the first thrust rod 51 of the longitudinal thrust rod, and the first surface of the first connecting plate 12 is provided with a plurality of first serrated members 13, and the first connecting plate 12 is also provided with a connecting through hole 14. Similarly, the second limiting member 2 is configured with a second arc end 21 and a second connecting plate 22. The inner wall of the second arc end 21 can be in close contact with the second thrust rod 52 of the longitudinal thrust rod, and the second surface of the second connecting plate 22 is provided with a plurality of second serrated members 23, and the second connecting plate 22 is also provided with a connecting through groove. And, the size of the second serrated member 23 is adapted to that of the first serrated member 13. The bolt connecting member 3 can pass through the connecting through hole 14 and the connecting through groove to connect and fix the first limiting member 1 and the second limiting member 2, and the first surface of the first connecting plate 12 is in close contact with the second surface of the second connecting plate 22, and the plurality of first serrated members 13 are engaged with the plurality of second serrated members 23. The longitudinal thrust rod assembly limiting structure is used to limit the relative movement of the first thrust rod 51 and the second thrust rod 52 through the first arc end 11 and the second arc end 21.

[0089] It can be seen from the above that the longitudinal thrust rod assembly limiting structure can fix the relative positions of the first thrust rod 51 and the second thrust rod 52 by the first arc end 11 and the second arc end 21 being respectively in close contact with the first thrust rod 51 and the second thrust rod 52, limit the relative movement of the first thrust rod 51 and the second thrust rod 52, improve the assembly efficiency, and improve the safety.

[0090] Preferably, the surfaces of the first limiting member 1 and the second limiting member 2 can also be marked with scales to improve the use efficiency.

[0091] Specifically, the surface of the first limiting member 1 is marked with a first total length 61, and the first total length 61 represents the preset length of the first limiting member 1. The surface of the second limiting member 2 is marked with a second total length 62, and the second total length 62 represents the preset length of the second limiting member 2.

[0092] Those skilled in the art can understand that the distance between the first push rod 51 and the second push rod 52 generally refers to the distance between the centers of the first push rod 51 and the second push rod 52. Therefore, the preset length of the first limiting member 1 can represent the length of the entire structure of the first limiting member 1 in a certain direction, or can represent the distance between the center of the first arc member and the end of the first connecting plate 12. Of course, it can also represent the length of at least part of the components of the first limiting member 1 determined in other ways, which is not limited in this specification. Among them, the end refers to the end of the first connecting plate 12 that is not connected to the first arc member. Similarly, the preset length of the second limiting member 2 can also represent corresponding two or more lengths.

[0093] Moreover, the surface of at least one first serrated member 13 is marked with a first engagement length, and / or the surface of at least one second serrated member 23 is marked with a second engagement length. Among them, the first engagement length represents the overlapping length of the first connecting plate 12 and the second connecting plate 22 when its corresponding first serrated member 13 meshes with the second serrated member 23, and when the first serrated member 13 adjacent to and closer to the first arc end 11 does not mesh with the second serrated member 23. Similarly, the second engagement length represents the overlapping length of the first connecting plate 12 and the second connecting plate 22 when its corresponding second serrated member 23 meshes with the first serrated member 13, and when the second serrated member 23 adjacent to and closer to the second arc end 21 does not mesh with the first serrated member 13.

[0094] Among them, the first direction is parallel to the extending direction of the first connecting plate 12. It should be emphasized that the first direction includes both the direction along the first connecting plate 12 towards the first arc member and the direction along the first connecting plate 12 away from the first arc member.

[0095] Further preferably, the surface of each first serrated member 13 is marked with a first engagement length.

[0096] Further preferably, the surface of each second serrated member 23 is marked with a second engagement length.

[0097] Further preferably, the surface of each first serrated member 13 is marked with a first engagement length, and the surface of each second serrated member 23 is marked with a second engagement length.

[0098] Figure 6 The structural schematic diagram of the longitudinal thrust rod assembly limiting structure provided for an embodiment of this specification is as follows Figure 6 As shown, the surface of the first limiting member 1 is marked with a first total length 61, the surface of the second limiting member 2 is marked with a second total length 62, the surface of each first serrated member 13 is marked with a first meshing length, and the surface of each second serrated member 23 is marked with a second meshing length.

[0099] Furthermore, the actual length of the longitudinal thrust rod assembly limiting structure can be determined by the following formula:

[0100] L 1 = A + B - c

[0101] where, L 1 is the actual length of the longitudinal thrust rod assembly limiting structure, A is the first total length 61, B is the second total length 62, c is the first meshing length marked on the first serrated member 13 that is in the meshing state and closest to the first arc end 11, or c is the second meshing length marked on the second serrated member 23 that is in the meshing state and closest to the second arc end 21.

[0102] Preferably, the sizes of the first serrated member 13 and the second serrated member 23 are both the first size value.

[0103] Preferably, the relative position of the first limiting member 1 and the second limiting member 2 can be adjusted in the first direction, and the indexing value of the adjustment can be determined by the following formula:

[0104] s = Pcosθ

[0105] where, s is the indexing value, P is the first size value, and θ is the angle between the first direction and the Euclidean direction. The Euclidean direction is the direction corresponding to the Euclidean distance between the first thrust rod 51 and the second thrust rod 52.

[0106] Adopting the above structure, the longitudinal thrust rod assembly limiting structure can adjust the relative position of the first limiting member 1 and the second limiting member 2 through a plurality of first serrated members 13 and a plurality of second serrated members 23.

[0107] Preferably, the first connecting plate 12 is further provided with a sliding groove, and the second connecting plate 22 is further provided with a sliding member. The sliding member can be embedded in the sliding groove and can slide along the sliding groove.

[0108] Further preferably, after the sliding member slides to a specific position, it can also be removed from the sliding groove.

[0109] In the above manner, during the process of fixing the first connecting plate 12 and the second connecting plate 22 through the bolt connecting member 3, the movement or attitude change of the first limiting member 1 and the second limiting member 2 can be prevented, the efficiency can be improved, and the user experience can be enhanced.
