Abstract

The invention provides a sub-frame structure compatible with various hanging supports. The sub-frame structure includes a hanging support and a sub-frame; the hanging support includes a swinging arm; the sub-frame includes a sub-frame body and a swinging installation support which is separately fixed on the sub-frame body; and the swinging arm installation support and the swinging arm are connected through bolt assemblies. According to the sub-frame structure compatible with various hanging supports, the sub-frame is divided into the sub-frame body and the swinging installation support is separately fixed on the sub-frame body, and the swinging installation support and the swinging arm of the vehicle hanging support are connected through the bolt assemblies, and in this way, when the size of the swinging arm changes or a swinging arm of a different hanging support is used, the swinging arm installation support can be changed so as to adapt to a design change of the hanging support without redesigning a whole sub-frame.

Description

technical field [0001] The invention belongs to the technical field of automobile chassis, in particular to a sub-frame structure compatible with various suspensions. Background technique [0002] The subframe is the skeleton of the front and rear axles. The front and rear suspensions can be assembled on the subframe first to form an assembly, and then the assembly is installed on the body together. For today's large-scale application of automotive platforms, the subframe changes the complex suspension system from parts to assemblies. The same suspension assembly can be installed on different bodies. At the same time, it is no longer necessary to develop a matching suspension for the body, but the assembly can be directly installed, and a good match can be achieved with a little adjustment. This assembly type axle can reduce the cost very well and improve the technical utilization rate. [0003] However, if the design of the hard point of the suspension changes (for examp...
