Brake Caliper Guide Layout to Prevent Inclination During Braking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional brake caliper devices are prone to inclination due to the weight of the positioning frame and brake pads, leading to a less smooth or nonfunctional braking process.
Innovation Solution
The brake caliper device features a positioning unit with upper and lower guiding members that maintain axial stability, a main body unit with movable seats, and an actuating unit using hydraulic pistons to generate a counterforce, ensuring the main body unit moves stably and prevents inclination during braking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the positioning frame extends through the upper portion of the first seat, then the brake caliper can be mounted to the vehicle body, but the positioning frame becomes easily inclined due to its own weight and the weights of the brake pads
Solution Approach 1:
The patent transitions from a single guiding member configuration to a multi-dimensional guiding system with upper and lower guiding members positioned at different vertical levels. This spatial arrangement creates a stable triangular support structure that prevents the positioning frame from inclining under gravitational load, thereby resolving the contradiction between mounting capability and stability.
Solution Approach 2:
The lower guiding member acts as an intermediary support element that mediates between the positioning frame and the vehicle body. By introducing this intermediate support point, the system distributes the gravitational load more effectively and prevents the positioning frame from becoming inclined, thus maintaining braking reliability while improving stability.
2Ease of operation
If the positioning frame is fixed to the vehicle body with guiding members, then the brake caliper can be positioned, but the braking process becomes less smooth or nonfunctional when the frame inclines
Solution Approach 1:
By adding the lower guiding member at a different vertical dimension, the system creates a rigid spatial framework that maintains the correct orientation of the brake caliper during braking operations. This prevents inclination-induced operational issues and ensures smooth, reliable braking performance.

AI summary
A brake caliper device (100) adapted to be used with a brake disk (2) includes a positioning unit (10), a main body unit (20), a lining unit (30), and an actuating unit (40). The positioning unit (10) includes a positioning member (11) that is adapted to be fixed to a vehicle body (1), two upper guiding members (12) and a lower guiding member (13) that is lower than the upper guiding members (12). The upper and lower guiding members (12, 13) are connected to the positioning member (11) and extend along an axial direction parallel to a central axis (L) of the brake disk (2) . The main body unit (20) is movably connected to the upper and lower guiding members (12, 13). The actuating unit (40) is operable to move the main body unit (20), thereby driving the lining unit (30) to clamp the brake disk (2).
