Rear-Axle Frame Receptacle Layout for Battery Space and Vibration Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing frame support structures for commercial vehicles face challenges in optimizing installation space for components like high-voltage batteries and fuel tanks due to limited space and off-center stress, which affects axle load distribution and vibration stability.
Innovation Solution
A frame support structure with a receptacle positioned behind the rear axle, allowing alternative use of space in front for other components, featuring a crash protection structure and damping elements to ensure even load distribution and reduce vibration impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the receptacle is mounted on the outside of the longitudinal member, then the installation space is utilized, but off-center loading occurs causing vibration excitation
Solution Approach 1:
The receptacle is positioned asymmetrically within the longitudinal member rather than on the outside, creating balanced load distribution that prevents off-center loading and reduces vibration excitation during vehicle operation
2Volume of moving object
If the receiving box occupies installation space in front of the rear axle, then the battery can be housed, but space for other components (e.g., fuel tank) is reduced
Solution Approach 1:
The receptacle is repositioned to the rear of the longitudinal member behind the rear axle, utilizing previously unused space in the rear dimension. This dimensional relocation allows the front installation space to be allocated to other components such as fuel tanks, thereby increasing overall vehicle configuration flexibility
3Quantity of substance
If a larger receiving box is provided for larger battery, then the battery capacity increases, but the mounting space constraints are violated
Solution Approach 1:
By relocating the receptacle to the rear dimension behind the rear axle, the patent creates additional mounting space that can accommodate larger batteries or multiple batteries without compromising the vehicle's front space requirements, thus resolving the space-capacity conflict

AI summary
The invention relates to a frame support structure (100), preferably a chassis, for a commercial vehicle, preferably a truck, in particular a semi-trailer truck. The frame support structure (100) comprises at least one receiving container (1) for at least one commercial vehicle component, two longitudinal beam structures (2) which are expediently spaced apart from each other in the transverse direction (Q) of the frame support structure (100), a rear axle (HA) for the commercial vehicle, and a rear cross member (3) which is preferably arranged behind the rear axle (HA). The frame support structure (100) is characterized in particular by the fact that the receiving container (1) is arranged behind the rear axle (HA).
