Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydraulic bearings for securing vehicle units like engines and transmissions to vehicle structures face challenges due to their structural height, which limits their use in spaces with insufficient structural space.
Innovation Solution
A vehicle unit fastening subassembly that includes a unit-side first carrier element and a vehicle-side second carrier element connected by a vibration damper with a hydraulic unit arranged beside it, reducing the structural height and allowing for more flexible integration into various structural spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If hydraulic bearings are used to support vehicle units in a vibratory manner, then vibration decoupling is achieved, but structural height increases due to the hydraulic unit
Solution Approach 1:
The patent transitions from a vertical stacking arrangement to a horizontal side-by-side arrangement of the vibration damper and hydraulic unit. This dimensional change allows both components to coexist without increasing structural height in the axial direction, while maintaining effective vibration decoupling through the vibration damper's suspension spring and bearing core.
2Object-affected harmful factors
If sufficient structural space is available for hydraulic bearings, then vibration decoupling is effective, but integration becomes difficult in regions with limited space such as engine and transmission areas
Solution Approach 1:
By arranging the vibration damper and hydraulic unit side-by-side in a horizontal configuration rather than stacking them vertically, the patent creates a compact assembly that adapts to limited structural spaces in engine and transmission regions while preserving vibration decoupling functionality.
3Length of stationary object
If the vibration damper and hydraulic unit are arranged side by side, then structural height is reduced, but flow channel connection complexity increases
Solution Approach 1:
The patent introduces a flow channel as an intermediary connection between the vibration damper and hydraulic unit. This flow channel enables hydraulic fluid communication between the two components arranged side-by-side, managing the complexity of connecting them horizontally while maintaining the reduced structural height benefit.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution reduces the structural height of the fastening subassembly, enabling easier integration into spaces with limited vertical clearance, while effectively transmitting bearing forces and damping vibrations to secure the vehicle unit.

AI summary
A vehicle unit fastening subassembly for vibratory fastening of a vehicle unit, in particular of a motor and/or transmission, to a vehicle structure of a motor vehicle, has at least one first carrier element on the unit side and a second carrier element on the vehicle side. The first carrier element and the second carrier element are connected to each other by a vibration damper, which is arranged at least in part in the first carrier element or in the second carrier element. The vibration damper is fluidically connected to a hydraulic unit by a flow channel, which is arranged adjacent to the vibration damper in a plan view of the vibration damper. A modular system is provided having a vibration damper and a hydraulic unit, wherein the vibration damper is usable either together with the hydraulic unit as a hydraulic vibration damper or without the hydraulic unit as a conventional bearing.
