Description

TECHNICAL FIELD

[0001] The present specification relates to the technical field of new energy commercial vehicle assembly, and particularly relates to a longitudinal thrust rod assembly limiting structure and a new energy commercial vehicle assembly system. BACKGROUND

[0002] Generally, large vehicles such as new energy commercial vehicles adopt a non-independent suspension structure, and a thrust rod is used 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 are respectively connected with the front axle end and the vehicle frame end. The longitudinal thrust rod includes a first thrust rod and a second thrust rod. However, since the ball hinge at the end of the first thrust rod and the second thrust rod is a rubber elastic element, it will be deformed and rotated under the action of gravity, resulting in that after the one end of the first thrust rod and the second thrust rod is assembled with the vehicle frame end or the front axle end, the distance between the first thrust rod and the second thrust rod cannot be controlled when the other end of the first thrust rod and the second thrust rod is assembled with the front axle end or the vehicle frame end, which increases the difficulty of assembly, reduces the efficiency, and also has safety hazards in manual assembly.

[0101] Wherein, L1 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, and c is the first meshing length marked on the first sawtooth member 13 in the meshing state and closest to the first arc-shaped end 11, or c is the second meshing length marked on the second sawtooth member 23 in the meshing state and closest to the second arc-shaped end 21.

[0102] Preferably, the size of the first sawtooth member 13 and the second sawtooth member 23 is a 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 adjustment index value can be determined by the following formula:

[0104] s=Pcosθ

[0105] Wherein, s is the index value, P is the first size value, and θ is the included 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] With 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 the plurality of first sawtooth members 13 and the plurality of second sawtooth members 23.
