Abstract

The invention relates to a vehicle frame longitudinal beam assembly for improving the NVH performance. The assembly comprises a vehicle frame longitudinal beam body, an L-shaped safety belt nut plate,an L-shaped seat installation nut plate and a floor reinforcing plate. The vehicle frame longitudinal beam body is of a long groove structure with a U-shaped cross section, longitudinal beam body turned edges are arranged on two sides of the vehicle frame longitudinal beam body in the length direction, the L-shaped safety belt nut plate is welded to the outer side face of the vehicle frame longitudinal beam body, the L-shaped seat installation nut plate is welded to the inside of a groove in the vehicle frame longitudinal beam body, and the floor reinforcing plate is welded to the top of thevehicle frame longitudinal beam body; and the two ends of the vehicle frame longitudinal beam body are in lap joint with a front crossbeam, a rear crossbeam and a floor, and the vehicle frame longitudinal beam assembly is arranged near a load sensing proportional valve support. The vehicle frame longitudinal beam assembly has the beneficial effects that the NVH problem that ride comfort is affected by large floor vibration is solved; safety belt installation point law and regulation failure risks are reduced; and seat installation point law and regulation failure risks are reduced.

Description

technical field [0001] The invention belongs to the field of automobile manufacturing, and in particular relates to a frame longitudinal beam assembly for improving NVH performance. Background technique [0002] With the development of the automobile industry, the requirements for automobile safety and NVH performance are getting higher and higher. The implementation of the three-point safety belt regulations has brought challenges to the design of the automobile body installation structure; the improvement of customer comfort requirements, the solution to the problem of body vibration and noise is becoming more and more important. Particularly important. [0003] The current common body structure mainly has the following problems: [0004] 1. Vehicle performance problems: the floor near the load-sensing proportional valve support lacks effective support, and the local mode of the floor is low under the vehicle’s working condition. When excited by the load-sensing proportio...
