Description

A new type of front subframe

technical field

The invention relates to the technical field of auto parts, in particular to a novel front subframe.

Background technique

The front subframe is an important component of the front suspension of the vehicle chassis system, mainly including the main body of the front subframe and the connection structure connected with the body, suspension and other parts. In addition to supporting the above parts, the front subframe can also block vibration and noise and reduce its direct entry into the car, so it mostly appears on luxury cars and off-road vehicles. The front subframe is a key structural part of the car chassis, and its own quality The lightweight of the whole vehicle is of great significance. Due to the safety requirements of the whole vehicle, its rigidity, modal and other performance requirements are extremely demanding. Therefore, how to use a more reasonable and excellent structure to achieve the ultimate lightweight while meeting the requirements has become extremely important. It is a subject of research significance. For this reason, we propose a new structure of the front subframe to achieve this goal.

The steering gear, an important assembly part of the existing front subframe, is an important component of the steering system, and its function is to actively change the traveling direction during the traveling process of the vehicle. The Y-direction rigidity requirement of the steering gear assembly point on the front subframe is very critical. The existing structure is relatively limited in improving the Y-direction rigidity of the front subframe steering gear installation point, thereby limiting the lightweight propulsion of the front subframe.
