Leaf spring mounts are commonly secured to the inside of a vehicle frame as an important load bearing component in a vehicle suspension system for mounting and supporting the leaf spring assembly for load transfer and cushioning purposes. While the steering wheel bracket is used as a mounting base of the steering system and is usually arranged on the outer side of the frame to connect the steering mechanism. To avoid spatial interference during installation of the two, conventional assembly procedures require that the steering wheel bracket be preferentially installed on the outside of the frame, and then the leaf spring mounting seat be assembled on the inside of the frame.

However, when a part of special vehicle types need to adjust the assembly sequence due to layout requirements, for example, the inside leaf spring mounting seat is preferentially mounted, because the overlapping area exists between the leaf spring mounting seat and the connecting piece (such as a bolt, a reinforcing rib or a welding boss) of the steering wheel bracket in space, the two parts will interfere rigidly, so that the steering wheel bracket cannot be normally mounted to a preset position.

From the above, the flexibility of the assembly process in the actual production process is insufficient due to the limitation of the assembly sequence, and especially, the problems of complicated assembly process, increased working hours and the like may be caused under the condition that the frame structure is compact or other accessory parts are interfered.

Therefore, how to improve the structure of the spring mounting seat to realize the compatibility of the spring mounting seat and the mounting sequence of the steering wheel bracket is a technical problem to be solved in the field.

In view of the above, the embodiment of the utility model provides a leaf spring mounting seat, a vehicle chassis and an automobile, wherein an avoidance notch matched with the outline of a connecting piece (such as a bolt head and a welding part) of a steering wheel bracket is arranged on a side plate, when the leaf spring mounting seat is preferentially mounted on the inner side of a frame, the avoidance notch can accommodate a local bulge or an extension part of the connecting piece, and the physical interference of the connecting piece and the side plate in the vertical direction and the horizontal direction is eliminated, so that the degree of freedom of the mounting sequence of the vehicle chassis is improved, the leaf spring mounting seat is allowed to be mounted firstly, then the steering wheel bracket is mounted, the reverse assembly requirement under special working conditions is met, and the assembly flexibility of the vehicle chassis is improved.
