Torque Rod Mounting Bracket for Thermal Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing torque rod systems face challenges in securely and compactly mounting an antivibration mass body, as high-temperature components like exhaust pipes cause rubber deterioration, making it difficult to maintain the mass body's attachment and affecting the torque rod's space requirements in narrow engine rooms.
Innovation Solution
A driving source support structure featuring an annular first end part with a projection part for mounting the mass body, a coupling part connecting the end parts, and a mounting bracket that shields the mass body and elastic bushes from high-temperature components, using a fastening member and rotation stoppers to secure the mass body and prevent thermal deterioration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mass body is mounted on the rubber member by vulcanization bonding, then the mass body is securely attached, but the heat from high-temperature members causes deterioration of the rubber member, making the mass body fall off
Solution Approach 1:
The patent introduces a mounting bracket as an intermediary component between the mass body and the torque rod. The bracket includes a shield that blocks heat from high-temperature members (exhaust pipes) from reaching the rubber member, thereby protecting the vulcanization bond from thermal deterioration while maintaining secure attachment of the mass body
Solution Approach 2:
The mounting structure is segmented into multiple functional components: the mounting bracket that provides structural support and shielding, the rubber member that provides vibration isolation, and the mass body that provides dynamic damping. This segmentation allows the shield to specifically address thermal protection without compromising the bonding function
2Object-affected harmful factors
If the mass body is mechanically fastened to the end part of the torque rod, then thermal deterioration is prevented, but it becomes difficult to secure space to dispose the torque rod in the narrow engine room
Solution Approach 1:
The mounting bracket merges multiple functions into a single component: it provides mechanical fastening to prevent thermal deterioration, supports the mass body, and includes integrated shielding against heat. This consolidation reduces the overall space required compared to separate components
3Volume of moving object
If the mass body is mounted compactly on the torque rod, then space is saved in the engine room, but it becomes difficult to securely fasten the mass body
Solution Approach 1:
The mounting bracket extends in multiple dimensions to provide secure fastening within compact constraints. The shield portion extends perpendicular to the torque rod axis to block heat, while the bracket structure provides multi-point attachment for the mass body, achieving both compactness and reliable fastening through three-dimensional spatial arrangement
