AI Technical Summary

Technical Problem

Conventional high-roof structures in trucks face challenges in distributing load evenly, leading to deformation of the cab body due to concentrated loads on the rear portion, especially when the roof panel is inclined to reduce air resistance.

Method used

A truck high-roof structure with a sloping roof panel and reinforced frames, including rear side frames with weaker sections, bracing rods, and additional frames to distribute loads evenly across the front and rear side frames, ensuring balanced load distribution and resistance.

Benefits of technology

The solution effectively suppresses cab body deformation by distributing loads evenly, ensuring robust resistance against overhead loads, thereby enhancing structural integrity.

Abstract

To provide a high roof structure for a truck, the structure suppressing deformation of a cab body against load from an upper side.SOLUTION: A high roof structure 1 for a truck is attached to an upper side of a cab body 10 having an open ceiling part. The high roof structure 1 comprises a pair of front side frames 2 and a pair of rear side frames 3 that support a roof panel inclined such that the vehicle height gradually increases from the front toward the rear. The front side frames 2 are installed upright from a pair of side wall parts 15 disposed at a position spaced apart in the vehicle width direction D2 on the cab body 10. The rear side frames 3 are installed upright behind the front side frames 2 so as to be higher than the front side frames 2 from the pair of side wall parts 15. At least one of the rear side frames 3 is provided with a fragile part 40 formed to have a lower strength than an adjacent site in a vehicle height direction D3.SELECTED DRAWING: Figure 2
