Disc Brake Support Segmentation for Pad Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In large-sized vehicles and industrial machines, the disc brake apparatus requires a high axial force for effective braking, leading to a heavy caliper body and complex, dangerous operations for pad replacement due to the need to remove and rotate the caliper body.
Innovation Solution
A disc brake apparatus with a support structure featuring torque receiving parts that can be divided, allowing for brake pad replacement without disassembling the caliper body, including a pad hold frame and a body hold frame arranged in a frame-like shape, enabling the caliper body to be held and the brake pads to be inserted or removed while maintaining the assembled state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the caliper body is upsized and an actuator is added to provide high axial force for high braking force, then the braking force is improved, but the weight of the apparatus increases
Solution Approach 1:
The support is divided into a first support part and a second support part that can be separated from each other. The brake pad is held between these two separable support parts, allowing the brake pad to be accessed and replaced without removing the entire caliper body. This segmentation enables maintenance access while keeping the heavy caliper body in place.
2Ease of repair
If the caliper body is removed and rotated to replace the brake pad, then the brake pad can be replaced, but the operations become complex and dangerous
Solution Approach 1:
The support is segmented into separable first and second support parts that can be moved relative to each other. This allows the brake pad to be accessed by separating the support parts while the caliper body remains in place, eliminating the need for complex removal and rotation operations.
Solution Approach 2:
The support parts are designed to be movable and reconfigurable. The first and second support parts can be separated and repositioned to provide access to the brake pad, then reassembled to maintain the caliper body's assembled state. This dynamic reconfiguration simplifies maintenance operations.
3Ease of repair
If the caliper body is removed for brake pad replacement, then the brake pad can be accessed, but the caliper body assembly state is disrupted
Solution Approach 1:
The support structure is segmented into separable first and second support parts that hold the brake pad. By separating only these support parts rather than the entire caliper body, the brake pad becomes accessible while the caliper body's overall assembly state is maintained.

AI summary
A disc brake apparatus that holds brake pads (46) and is capable of holding a caliper body (30) in a part of the support is provided with a support in which pairs of torque receiving parts (16, 18) provided in both sides in a braking force tangential direction and connecting parts (20) respectively connecting together the torque receiving parts (16, 18) are provided in both sides in an axial-direction of a rotor. In the support, at least one of the torque receiving parts (16, 18) is capable of being divided. The support (12) includes an open part capable of inserting and removing the brake pads (46) in the braking force tangential direction by dividing the torque receiving parts.
