Description

Technical Field

[0001] The utility model relates to the technical field of commercial vehicles, in particular to a commercial vehicle. Background Art

[0002] At present, due to the large size of commercial vehicle doors and the characteristics of the structure and installation of the left and right exterior mirrors, the upper installation points of the left and right exterior mirrors are often selected on the doors (near the intersection of the A-pillar and the cab ceiling), which will increase the load on the doors at the upper installation points of the exterior mirrors. Therefore, the product consistency, installation process and precision of commercial vehicle doors are relatively high. At the same time, the design should also consider the modal distribution of the doors, the modal distribution of the left and right exterior mirrors, the vibration isolation performance of the soft pad of the cab suspension system, the vibration isolation performance of the powertrain suspension system and the unsprung frequency deviation of the suspension system, that is, to avoid the coupling between the power system excitation frequency and the unsprung frequency deviation of the suspension system under the common working conditions of the vehicle and the first two modes of the left and right exterior mirrors, and to match the vibration isolation performance of each vibration reduction system.

[0003] In the prior art, there is a phenomenon of doors flashing outwards in commercial vehicle models when the vehicle is traveling at a speed of 60km / h or above. The greater the road excitation and the higher the wind speed, the more obvious the door flashing outwards phenomenon is. At the same time, the exterior rearview mirrors will also be affected to cause different degrees of shaking, increased noise inside the car, reduced voice clarity inside the car and other NVH problems, resulting in a decrease in the vehicle's NVH performance and reducing the vehicle's practicality.
