Brake Caliper Self-Aligning Module Prevents Push Arm Fracture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional brake calipers suffer from angular misalignment issues between the push member and the side seat, leading to interference and potential fracture of components.
Innovation Solution
Incorporation of a self-aligning module with a self-aligning joint, such as a ball stud and socket, or a self-aligning bearing with an inner and outer ring, to allow for misalignment without interference between the extension tube and the axle through hole, preventing fractures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional brake caliper structure is used without self-aligning features, then the structure is simple and easy to manufacture, but angular misalignment between the push member and side seat causes interference and component fracture
Solution Approach 1:
A self-aligning module is introduced as an intermediary component between the push member and the side seat. This module includes a connection hole with a non-circular cross-section that matches a corresponding non-circular connection portion, serving as a mediator that accommodates angular misalignment while maintaining reliable mechanical connection, thereby preventing component fracture without significantly complicating the overall structure
Solution Approach 2:
The connection hole is designed with a non-circular cross-section rather than a conventional circular one. This parameter change in the geometric shape allows the connection to accommodate angular misalignment between the push member and side seat, enabling the connection to adapt to varying alignment conditions while maintaining structural integrity and preventing fracture
2Ease of operation
If rigid alignment between push member extension tube and side seat axle through hole is enforced, then manufacturing precision can be controlled, but any angular misalignment causes interference and fracture
Solution Approach 1:
The self-aligning module introduces dynamic adaptability to the previously static rigid connection. The non-circular connection hole and corresponding portion allow relative rotational movement and angular adjustment, enabling the connection to dynamically adapt to misalignment conditions during assembly and operation, thereby improving ease of operation while maintaining adequate manufacturing precision

AI summary
A brake caliper (100) includes a main body unit (10), a braking unit (30) and an actuating unit (40). The main body unit (10) includes interconnected first and second side seats (11, 12). Thebrakingunit (30) includes first and second push arm assemblies (31, 32) respectively mounted to the first and second side seats (11, 12). The actuating unit (40) is for moving at least a portion of the first push arm assembly (31). The first push arm assembly (31) includes a self-aligning module (60) including at least one self-aligning joint, so that misalignment between the first side seat (11) and a portion of the first push arm assembly (31) without interference between the first push arm assembly (31) and the first side seat (11) is permitted.
