Transmission Mount Stopper Integration for Lateral Displacement Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stopper structures for TM mounts in vehicles are inefficient in controlling lateral displacement, leading to handling performance issues and increased costs due to separate stoppers, which also cause abnormal noise and durability problems.
Innovation Solution
A stopper structure integrated into the TM mount, featuring a housing bracket, a lower plate connected to the vehicle body via a curling structure, an inner core with a bridge to control lateral displacement, and a reinforcing material with an inclined surface to manage lateral movement and improve rubber properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate stopper is mounted outside the TM mount to control lateral displacement, then handling performance is improved, but costs and weight increase
Solution Approach 1:
The patent merges the stopper function with the housing bracket by integrating a stopper protrusion directly into the housing bracket structure. This eliminates the need for a separate stopper component, reducing part count, weight, and manufacturing costs while maintaining the lateral displacement control function that improves handling performance.
2Ease of operation
If a separate stopper is mounted outside the TM mount to control lateral displacement, then handling performance is improved, but device complexity increases
Solution Approach 1:
The stopper protrusion is integrated into the housing bracket as a unified structure, eliminating the need for separate stopper components and their associated mounting operations. This reduces device complexity by consolidating the stopper function within the existing housing bracket geometry.
3Ease of operation
If a separate stopper is mounted outside the TM mount to control lateral displacement, then handling performance is improved, but durability deteriorates due to bonding weakness
Solution Approach 1:
The stopper protrusion is formed as an integral part of the housing bracket through injection molding or similar manufacturing processes. This eliminates bonding interfaces that were previously weak points, ensuring the stopper function is maintained with the same durability as the housing bracket itself.
4Ease of operation
If a separate stopper is mounted outside the TM mount to control lateral displacement, then handling performance is improved, but costs increase
Solution Approach 1:
The stopper protrusion is integrated into the housing bracket as a single molded part, eliminating the need for separate stopper components, bonding materials, and additional assembly steps. This consolidation reduces manufacturing costs while maintaining the lateral displacement control function that improves handling performance.
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
This solution reduces costs and weight by eliminating the separate stopper, enhances handling performance by improving rubber spring properties in the lateral direction, and addresses abnormal noise issues by performing the stopper function within the insulator, thereby improving vehicle handling and integrity.
Implementation Method 1
an insulator 5 made of a material (e.g., rubber or synthetic resin, etc.) having elasticity is coupled to a metallic inner core 6 and embedded, together with the inner core 6, in a housing bracket 4... the inner core 6 is fastened, by bolting, to the transmission bracket 2 coupled to the transmission 1, supports a load of the power train at the side of the transmission, and insulates vibration as the insulator 5 is elastically deformed
Implementation Method 2
a lower plate which is positioned at a lower end of the insulator and connected, together with the housing bracket, to a vehicle body through a curling structure
Implementation Method 3
a bridge which is installed at a lower side of the inner core so as to control a lateral displacement... a bridge that controls a lateral displacement by itself

AI summary
The present disclosure relates to a transmission (TM) mount that is capable of reducing costs and a weight by removing a separate stopper (component). The transmission (TM) mount improves handling performance taking advantage of elastic properties of a rubber component in a left/right direction (lateral direction). The stopper for a transmission (TM) mount includes a housing bracket into which an insulator is press-fitted, a lower plate which is positioned at a lower end of the insulator and connected, together with the housing bracket, to a vehicle body through a curling structure, an inner core which is disposed at a central portion of the insulator, and a bridge which is installed at a lower side of the inner core so as to control a lateral displacement. The bridge is tightly fixed to a fixing piece formed in the lower plate.
