Description

Auxiliary frame assembly behind car Technical Field The utility model relates to the technical field of frame assemblies, in particular to an automobile rear auxiliary frame assembly. Background The subframe may be considered as the backbone of the front and rear axles, which are integral parts of the front and rear axles. The subframe is not a complete frame, but is simply a bracket that supports the front and rear axles, and the suspension, through which the axles, suspension are then connected to the "positive frame", conventionally referred to as the "subframe". The sub-frame is used for blocking vibration and noise and reducing the noise from directly entering the carriage, so that the sub-frame is mostly arranged on luxury cars and off-road vehicles, and some cars are also provided with the sub-frame for the engine. The conventional load-bearing vehicle body without a subframe has a suspension directly connected to the steel plate of the vehicle body. The front and rear axles are thus all part and not an assembly. After the subframe is produced, the front and rear suspensions can be assembled on the subframe to form an axle assembly, and then the assembly is mounted on the vehicle body together. At present, the existing automobile rear auxiliary frame is mostly formed by welding, in the welding process, the welding is usually carried out along the edge of the frame splicing, and the welding of the front cross beam, the rear cross beam, the left longitudinal beam and the right longitudinal beam is difficult to ensure in place, so that cracks are easily formed in the welded positions of the frame in the later use process, the strength of the frame is not ensured, and the safety of the vehicle is reduced.
