Description

Novel steel frame type rear auxiliary frame
[ technical field ]
The utility model belongs to the technical field of the automobile parts technique and specifically relates to a novel steel frame back sub vehicle frame.
[ background art ]
The auxiliary frame is a framework of the front axle and the rear axle and is a constituent part of the front axle and the rear axle. The subframe is not a complete frame, but merely a bracket that supports the front and rear axles and the suspension, through which the axles and suspension are again connected to the "right frame", conventionally referred to as the "subframe". The sub-frame has the functions of isolating vibration and noise and reducing direct entering of the sub-frame into a carriage, so that the sub-frame is mostly arranged on luxury cars and off-road vehicles, and the sub-frame is also arranged on an engine of some vehicles. In the conventional vehicle body without the subframe, the suspension is directly connected with the steel plate of the vehicle body, so that the suspension rocker mechanisms of the front axle and the rear axle are both parts and not assemblies.
After the subframe is produced, the front and rear suspensions may be assembled to the subframe to form an axle assembly, which is then mounted to the vehicle body.
