AI Technical Summary

Technical Problem

Existing technologies cannot simultaneously meet the requirements of comfort in the driver's area and space in the rest area of ​​commercial vehicles. Conventional solutions cannot prevent vibrations from the driver's area from being transmitted to the rest area, thus encroaching on the rest area space.

Method used

Design a front-end module for a vehicle frame, including a driver's area and a rest area, which are connected by main longitudinal beams and main cross beams to form a strong frame structure. The main cross beam is located at the junction of the driver's area and the rest area, serving as a key barrier for the transmission of vibration energy, repeatedly transmitting and consuming vibration excitation, dispersing energy, and ensuring NVH performance.

Benefits of technology

The rigidity and modal frequency of the front-end module of the chassis have been improved, effectively dispersing vibration energy and ensuring the NVH performance of the driver's area. At the same time, a rest area has been left in the vertical direction to meet the driver's rest needs.

Abstract

This utility model belongs to the field of vehicle underbody structure, specifically providing a front-end module of a chassis, a chassis, and a vehicle. The module includes a driver's area and a rest area. The driver's area includes a front upper main longitudinal beam, a left front lower main longitudinal beam, and a right front lower main longitudinal beam. The left or right front lower main longitudinal beam is located directly below the front upper main longitudinal beam. The rear end of the front upper main longitudinal beam is connected to a main crossbeam. The rest area includes a left rear main longitudinal beam and a right rear main longitudinal beam. The left and right rear main longitudinal beams connect to the front axle module of the chassis. The main crossbeam is connected to a middle crossbeam via a left upper vertical beam and a right upper vertical beam. The left and right upper vertical beams are located in front of the left and right rear main longitudinal beams, respectively. The left front lower main longitudinal beam, right front lower main longitudinal beam, left rear main longitudinal beam, and right rear main longitudinal beam are all connected to the middle crossbeam. The chassis includes the above module. The vehicle includes the above chassis. This utility model, while meeting NVH performance requirements, retains a rest area to meet the driver's rest needs.
