At present, the connection mode of fig. 1 and 2 is widely adopted for the V-shaped thrust rod bracket and the frame. As shown in fig. 1, the V-shaped thrust rod bracket 4 is connected with the cross beam 5 and the longitudinal beam 1 at the same time, and the connection mode has high requirements on the assembly accuracy of the frame system, and increases the manufacturing and installation cost. One approach to reducing the difficulty of installation is to increase the bolt hole and bolt size, such as with oblong holes, but this approach reduces the reliability of use and increases the cost. The other method is to weld the bracket 4 with the longitudinal beam 1 and bolt the bracket 4 with the transverse beam 5, but the method has high requirements on the welding process, otherwise, the reliability can not meet the use requirements, and the working procedure and the process cost are increased. As shown in fig. 2, the V-shaped thrust rod bracket 4 is only connected with the longitudinal beam 1, and the middle and rear axles can share one bracket, but the method requires that the cross beam 5 is provided with a large through hole at the connection part with the longitudinal beam 1, the structure can reduce the rigidity of the frame at the position, the frame deforms more when bearing load, the stress condition of the large bracket of the balanced suspension at the position is worse, and the reliability of the suspension system is reduced.
In summary, the existing connection between the V-shaped thrust rod support and the vehicle frame has the defects of high process requirement, high manufacturing cost and poor use reliability, so that the development of a novel connection mode between the V-shaped thrust rod support and the vehicle frame is urgently needed to overcome the defects of the connection mode in the prior art.
