Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional attachment devices between trailing arms and track support beams in tracked vehicles are weak, complex, and costly, leading to reduced life expectancy and increased service needs, with inadequate suspension and structural strength.
Innovation Solution
A robust attachment device is designed with a solid part attached to the track support beam via a recess, featuring a pivotal attachment mechanism with a pin or ball joint, providing additional structural strength and stability by engaging the trailing arm parallel to the track support beam's longitudinal direction, and incorporating a torsion spring for resilient movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional attachment devices are used between trailing arms and track support beams, then the device complexity is reduced, but the structural strength and reliability deteriorate
Solution Approach 1:
The attachment device merges the trailing arm connection and the track support beam connection into a single integrated structure. The U-shaped attachment device has arms that connect to the trailing arm and a base that connects to the track support beam, combining multiple attachment functions into one unified component that provides both structural strength and suspension capability.
Solution Approach 2:
The attachment device utilizes composite construction with a U-shaped configuration that combines rigid connection points with flexible suspension elements. The structure integrates metal components with potential rubber or polymer elements to achieve both strength and resilience in a single attachment device.
2Ease of manufacture
If conventional attachment devices are used, then the manufacturing cost is reduced, but the life expectancy and service interval deteriorate
Solution Approach 1:
The attachment device is designed as a separable U-shaped component that can be manufactured independently and then installed on the track support beam. This segmentation allows for specialized manufacturing processes optimized for the attachment device geometry, improving both manufacturing efficiency and component durability through focused production techniques.
Solution Approach 2:
The attachment device is pre-configured with its U-shaped geometry and connection features during manufacturing, allowing for quality control and stress testing to be performed before installation. This preliminary preparation ensures the device meets strength requirements while maintaining manufacturing efficiency through standardized production processes.
3Device complexity
If conventional attachment devices are used, then the device simplicity is maintained, but the suspension capability and stability deteriorate
Solution Approach 1:
The attachment device incorporates dynamic suspension capability through its U-shaped configuration that allows controlled movement and rotation. The device can pivot and flex to accommodate track assembly movement while maintaining stable connection, providing both simplicity in structure and sophistication in movement capability.
Solution Approach 2:
The attachment device utilizes changes in geometric parameters during operation, allowing the U-shaped structure to flex and rotate within defined ranges. This parameter change capability enables the device to maintain stable connections while accommodating the dynamic movement of the track assembly, achieving both simplicity and stability.
