Vehicle Powertrain Mounting Assembly with Locating Pin Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting assemblies for vehicle powertrains lack efficient alignment and stress distribution mechanisms, leading to potential misalignment and uneven load distribution during assembly and operation.
Innovation Solution
A mounting assembly comprising a first assembly portion with a bracket and locating pin, and a second assembly portion with a base plate and bushing, which aligns and positions the powertrain relative to the vehicle frame using a locating pin and bushing system, distributing stress evenly across components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional mounting assemblies are used without a locating pin system, then the assembly structure is simpler, but misalignment and positioning errors occur during assembly
Solution Approach 1:
The locating pin acts as an intermediary element between the powertrain and vehicle frame, providing precise alignment and positioning. The pin fits into corresponding bores in both components, serving as a mediator that ensures accurate relative positioning without requiring complex adjustment mechanisms.
Solution Approach 2:
The locating pin system performs preliminary alignment action before final fastening. By inserting the locating pin into the bores of both components first, the correct position is established in advance, preventing misalignment during the subsequent fastening operations.
2Strength
If conventional mounting assemblies without stress distribution features are used, then the structure is simpler, but uneven load distribution causes stress concentration and potential failure
Solution Approach 1:
The mounting assembly is segmented into multiple load-bearing elements including the locating pin, base plate, and multiple fastening points. This segmentation distributes the overall load across several discrete components rather than concentrating it at a single point, reducing stress concentration on any individual element.
Solution Approach 2:
The base plate incorporates localized reinforcement and varying thickness profiles to distribute stress evenly across different regions. Areas experiencing higher loads are thickened or reinforced, while less stressed areas remain thinner, optimizing the stress distribution pattern throughout the mounting assembly.
3Stability of the object's composition
If rigid mounting assemblies are used, then structural stability is better, but the assembly cannot accommodate dynamic movements and vibrations during vehicle operation
Solution Approach 1:
The mounting assembly incorporates dynamic characteristics through the locating pin system that allows controlled movement. The pin fits loosely enough in the bores to permit thermal expansion and vibration-induced movements, while maintaining sufficient constraint to prevent misalignment under normal operating conditions.

AI summary
A mounting assembly is provided. The mounting assembly includes a first assembly portion coupled to a first component and a second assembly portion coupled to a second component. The first assembly portion includes a first bracket and a locating pin. The first bracket has a first surface, a second surface, and defines a first bracket protrusion having a first bracket bore therein. The locating pin has a first end, a second end, and an exterior surface. The first end of the locating pin is fixedly mounted within the first bracket bore. The second assembly portion includes a base plate that has a base plate first surface and a base plate second surface and defines a base plate protrusion portion having a protrusion bore therein. The locating pin is configured to be inserted into the protrusion bore in order to position the first component with respect to the second component.
