Torque Support Bearing Core Deformation for Engine Roll Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing torque supports for drive motors in vehicles require larger openings in the vehicle chassis, which weakens the structure, increases weight, and production costs due to multiple components, and complicates assembly.
Innovation Solution
A torque support design using a single-piece bearing core with a recess and notch, allowing resilient or plastic deformation for improved clamping and reduced component count, simplifying assembly and reducing engine roll.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a torque support uses multiple bearing cores and bearing bushes, then the clamping action is improved, but the device complexity increases and assembly time increases
Solution Approach 1:
The patent combines multiple bearing cores and bearing bushes into a single integrated bearing unit. The bearing unit comprises a single bearing core with multiple bearing bushes arranged around it, eliminating the need for separate bearing cores and reducing the total number of components while maintaining the clamping function through the resilient deformation of the bearing bushes.
Solution Approach 2:
The bearing core is designed with multiple bearing bushes that can deform independently, allowing each bush to contribute to the clamping action on different sides of the support member. This segmentation of the bearing function within a single core maintains effective clamping while reducing overall device complexity.
2Strength
If a torque support uses multiple bearing cores, then the clamping action is improved, but the assembly time increases
Solution Approach 1:
By integrating multiple bearing bushes around a single bearing core, the patent reduces the number of separate components that need to be positioned and assembled. The single bearing unit can be installed as one piece, significantly reducing assembly time compared to assembling multiple separate bearing cores and bushes.
Solution Approach 2:
The bearing bushes are pre-positioned around the bearing core during manufacturing, creating a pre-assembled bearing unit. This preliminary arrangement of components eliminates the need for complex on-site assembly of multiple bearing parts, reducing assembly time while maintaining the multi-directional clamping capability.
3Adaptability or versatility
If larger openings are used in the vehicle chassis for torque support, then the torque support can be accommodated, but the vehicle structure is weakened
Solution Approach 1:
The patent employs resilient bearing bushes that deform in multiple directions to accommodate the support member. This multi-dimensional deformation capability allows the bearing unit to adapt to the support member without requiring large openings in the vehicle chassis, thereby maintaining structural integrity while providing necessary accommodation.

AI summary
A system for an engine torque support is described comprising a support member connected to a vehicle structure at a first end via a bearing comprising a bearing core surrounded by a bearing bush. The bearing bush has a recess, and the bearing core includes a receiving channel for a connector, a notch extending transversely relative to the receiving channel, and a connection web formed in a plane of the notch creating a first core portion, and a second core portion of the bearing core. The second core portion is spaced apart from the first core portion by the notch, and the second core portion is displaced relative to the first core portion via resilient deformation of the connection web and/or via breaking of the connection web.
