As described in the background art, in the conventional front wheel mounting assembly, when the front wheel is impacted from the front, the mounting end connected with the front wheel receives a first acting force from the front, the first acting force can be decomposed into a first component force towards the disengaging direction of the disengaging end and a second component force perpendicular to the disengaging direction of the disengaging end, the first component force and the second component force are transmitted to the disengaging end along with the swing arm, the disengaging end can only depend on the action of the first acting force, and the condition that the disengaging end can be disengaged from the front subframe under the action of the first component force needs to be ensured. Because the magnitude of the first component force decomposed by the first acting force is limited, if the connection strength of the disconnection end and the front subframe is too high, the disconnection end cannot be disconnected by the first component force, so that the disconnection end can be disconnected from the front subframe only by weakening the strength of the connection part of the disconnection end and the front subframe when the front wheel is impacted from the front, the fatigue resistance and the durability of the connection part of the disconnection end and the front subframe are reduced, and the design contradiction between the fatigue resistance and the durability of the front wheel assembly and the collision safety performance is raised.
In order to solve the technical problem, the inventor of the scheme constructs the swing arm of the front wheel mounting assembly into a structure that when a mounting end receives a first acting force which is from the front and is larger than a preset threshold value, a first arm section deforms towards a front auxiliary frame and presses the front auxiliary frame, when the first arm section deforms and presses the front auxiliary frame, the front auxiliary frame generates a second acting force which is equal to and opposite to the contact pressure of the first arm section to the front auxiliary frame on the first arm section, the second acting force can be decomposed into a third component force facing a disengaging direction of the disengaging end and a fourth component force perpendicular to the disengaging direction of the disengaging end, the third component force and the fourth component force are transmitted to the disengaging end along with the swing arm, and the third component force and a first component force facing the disengaging direction and resolved from the first acting force transmitted to the disengaging end along with the swing arm form a disengaging force for disengaging the disengaging end. When the front wheel mounting assembly is impacted to generate first acting force with the same degree, the action of second acting force generated by the front auxiliary frame is added at the release end, the release force borne by the release end is obviously increased, the release end can still be released when the connection strength of the release end and the front auxiliary frame is higher, the release end can be released without weakening the strength of the connection part of the release end and the front auxiliary frame, the connection strength of the release end and the front auxiliary frame can be higher, the improvement of the fatigue resistance and the durability of the connection part of the release end and the front auxiliary frame is facilitated, and the design contradiction between the fatigue resistance and the durability of the front wheel mounting assembly and the collision safety performance is solved.
The front wheel mounting assembly and the automobile provided by the application are described in detail with reference to specific embodiments.

In some possible embodiments, the bending strength of at least part of first arm segment 210 is less than the bending strength of second arm segment 220.
With this arrangement, the second arm section 220 can be bent first to press the front subframe 100 while maintaining the shape of the first arm section 210. The first arm section 210 is bent when the mounting end 221 is acted by the first acting force by adjusting the strength of each part of the swing arm 200, and the structure is simple, the manufacture is convenient and the cost is low.
