Control and promotion of vertical stiffness of door
The door is the key moving part of the body, and is also one of the most frequently used systems of the whole vehicle. The role of the door of modern automobile has gone beyond the role of "door", and become a symbol of the automobile. The quality of the door is directly related to the comfort and safety of the vehicle. If the doors are of low performance, poor quality or poorly made, it will increase the noise and vibration inside the car, making passengers uncomfortable or even unsafe. Therefore, in the development of automotive products, attention should be paid to the development and design of the door, to ensure that the performance of the door not only meet the technical standards of the enterprise, but also meet the requirements of customers.
The vertical stiffness of the door is an important content of the door stiffness, and is one of the most important criteria to measure the performance of the door. Therefore, attention must be paid to the control and improvement of the vertical stiffness performance of the door, and strict control and check should be carried out in the whole process of the door system development. At the same time, in the process of door vertical stiffness control and upgrading, the relationship between door stiffness performance and door weight and cost must be coordinated.
2. Increase the lower arm limit within a certain range to make the lower arm limit work earlier in the process of vehicle jumping, so as to avoid the hard contact between the tire and the leaf plate often.
