Axle Guide Lifting Device Console Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lifting devices for vehicle axles face high mechanical stress due to permanent connection to the chassis, and require adaptable dimensions to accommodate different vehicle types and driving heights, which is not efficiently addressed by current designs.
Innovation Solution
A lifting device with a pressure pickup on a separate console that can be easily attached to the axle link via plug-in or hook connections and screw/bolt connections, allowing for adjustable positioning and reduced mechanical stress by decoupling the force element from the wishbone during non-operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the force element is permanently connected to the wishbone, then the lifting device provides stable support, but high mechanical stress accumulates on the lifting device and its parts during chassis deflection
Solution Approach 1:
The lifting device is divided into two mechanically separate main components: a force member (membrane cylinder) fastened under the support, and a pressure absorber arranged on the wishbone. The pressure transmission acts as a movable connector between them, allowing the force member to be decoupled from the wishbone during non-operation while maintaining stable support during lifting.
2Adaptability or versatility
If the same wishbones are combined with supports of different heights and air bags with different offsets, then different vehicle types and driving heights are accommodated, but the pivoting range varies and requires adaptable lifting device dimensions
Solution Approach 1:
The console with the pressure absorber is designed to be pivotably mounted on the wishbone rather than rigidly fixed. This dynamic mounting allows the console to automatically adjust its position and orientation to accommodate different vehicle types, driving heights, and pivoting ranges without requiring different lifting device dimensions.
Solution Approach 2:
The lifting device is designed with universal dimensions and geometry that can accommodate different vehicle types and driving heights. The pivotable console and standardized force member design allow the same lifting device to function across multiple applications without requiring dimensional adaptations.
3Strength
If the pressure absorber is integrated into the wishbone structure, then the lifting forces are directly transmitted, but the lifting device cannot be easily adapted to different geometries
Solution Approach 1:
The pressure absorber is separated from the wishbone structure and placed on a dedicated console that can be pivotably mounted. This segmentation allows the lifting forces to be safely transmitted through the console while maintaining the ability to easily adapt the console's position and orientation to different geometries.

AI summary
The lifting device has a pressure housing (15A) formed on a bracket (15) that is fastened to an axle guide (5), where a free end of a pressure transmission (18,20) is formed by a roller. The fastening of the bracket is divided into a one plug-in or hook connection and another connection, particularly screw-, bolt and latching connection. The bracket is adjusted in two different positions relative to the axle guide, where the bracket is comprised of an adjusting element, on which the pressure housing and multiple locking structures are formed. An independent claim is provided for an axle guide with a bore.
