Electrified Vehicle Suspension Linkage Layout for Battery Rail Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional suspension assemblies in vehicles limit the space available for mounting batteries by extending into the space between frame rails, preventing the installation of larger or more batteries.
Innovation Solution
A suspension assembly design with linkage rods that extend laterally outwardly from the central longitudinal axis, creating additional space between frame rails for mounting batteries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If conventional suspension assemblies extend into the space between frame rails, then suspension function is maintained, but space for mounting batteries is reduced
Solution Approach 1:
The linkage rods are arranged at angles relative to the central longitudinal axis, extending laterally outwardly from the axis. This angular arrangement in a different dimensional orientation creates clearance between the linkage rods and the centerline, thereby increasing the available space between frame rails for battery mounting while preserving suspension functionality.
2Area of stationary object
If linkage rods are arranged at an angle laterally outwardly, then space for batteries is increased, but structural complexity of suspension assembly increases
Solution Approach 1:
The linkage rods are positioned asymmetrically at angles relative to the central longitudinal axis rather than symmetrically along the axis. This asymmetric angular arrangement optimizes the use of available space by directing linkage rods laterally outwardly, creating an uneven distribution that maximizes central space for battery installation.
3Quantity of substance
If suspension assembly uses traditional configuration, then manufacturing is simpler, but energy storage capacity is limited
Solution Approach 1:
By arranging linkage rods at angles laterally outwardly from the central longitudinal axis rather than in a traditional linear configuration, the design opens up additional three-dimensional space between the frame rails. This dimensional reconfiguration allows for increased battery capacity without adding complex mechanical components or manufacturing steps.

AI summary
A suspension assembly for an electrified vehicle includes a first linkage rod coupled to a first bracket and a second linkage rod coupled to a second bracket. The first linkage rod is arranged at an angle relative to a central longitudinal axis so that as the first linkage rod extends from the axle housing toward the first bracket, the first linkage rod angles laterally outwardly and away from the central longitudinal axis. The second linkage rod is arranged at an angle relative to the central longitudinal axis so that as the second linkage rod extends from the axle housing toward the second bracket, the second linkage rod angles laterally outwardly and away from the central longitudinal axis.
