Integrated Torque Roll Restrictor Damper Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicles require separate torque roll restrictors and dampers, which occupy space and increase assembly and maintenance costs due to their distinct components.
Innovation Solution
A torque roll restrictor assembly with an integrated damper, featuring a first member connected to the vehicle body, a second member connected to the powertrain, and a damper within the assembly, utilizing bushings and a friction material for damping, allowing for articulation and reduced component count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate torque roll restrictors and dampers are used, then each component can be optimized for its specific function, but the vehicle requires more space and incurs higher assembly and maintenance costs
Solution Approach 1:
The patent combines the torque roll restrictor and damper into a single integrated assembly where the restrictor housing forms the damper mounting structure. The restrictor body serves as both the torque management component and the structural housing for the damper, eliminating the need for separate mounting brackets and fasteners while maintaining the functional independence of both components
Solution Approach 2:
The restrictor housing performs multiple functions: it contains the torque restrictor mechanism, provides structural support, and serves as the mounting structure for the damper. This multi-functional design reduces the overall component count while maintaining the specialized functions of each element
2Ease of repair
If separate torque roll restrictors and dampers are installed, then each component can be independently maintained, but assembly and maintenance costs increase
Solution Approach 1:
The integrated assembly is designed with modular segments where the torque restrictor and damper can be independently accessed and removed. The restrictor can be detached from the housing, and the damper can be removed from its mounting structure, allowing separate maintenance of each component while benefiting from the space-saving integrated design
3Reliability
If multiple separate components are used, then each component can be optimized for its specific operation, but the space required in the vehicle increases
Solution Approach 1:
The damper is nested within the restrictor housing structure, with the damper body positioned inside the hollow cavity of the restrictor assembly. This nesting arrangement allows the damper to utilize the internal space of the restrictor housing, significantly reducing the overall volume occupied by the combined components

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 integrated design minimizes space requirements and reduces assembly and maintenance costs while effectively managing load and impulse events through enhanced damping and articulation capabilities.
Implementation Method 1
The friction material may be configured to engage with an inner surface of the cylindrical wall to provide a damping effect
Implementation Method 2
a damper connected to the first member. A first member may include at least one bushing disposed between the inner wall and the outer wall

AI summary
A torque roll restrictor assembly for a vehicle includes a first member configured for connection with a body of a vehicle, a second member rotatably connected to the first member and configured for connection with a powertrain of said vehicle, and a damper connected to the first member. A first member may include a first portion, a second portion to which the second member may be rotatably connected, and a third portion connecting the first portion and the second portion. A first portion of the first member may include an outer wall, an inner wall defining a channel, at least one bushing disposed between the inner wall and the outer wall, and a connector configured to connect the first member to said body of said vehicle. A connector may be at least partially disposed within the channel.
