Motorcycle ABS Unit Mounting via Segmented Bracket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional motorcycle hydraulic braking systems face challenges in mass concentration and maintenance due to the placement of the ABS unit, which is often located away from the engine, making it difficult to detach and maintain, and the complexity of brake piping when valves and hydraulic pumps are distributed across different locations.
Innovation Solution
A motorcycle design featuring a two-divided bracket system that allows the hydraulic unit to be attached to the main frame via a main bracket member and a sub-bracket member, enabling easy detachment and improved mass concentration by placing the hydraulic unit near the engine, while maintaining compactness and protecting it from external damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the ABS unit is arranged in the rear portion of the vehicle away from the engine, then the heavy articles or parts for the vehicle are distributively arranged, but this results in inhibiting mass concentration
Solution Approach 1:
The bracket is divided into a main bracket member fixed to the frame and a sub-bracket member to which the ABS unit is attached. The sub-bracket member can be detached from the main bracket member, allowing the ABS unit to be removed without detaching the engine or other heavy components. This segmentation enables easy maintenance while maintaining proper mass distribution.
2Area of stationary object
If the ABS unit is arranged in the rear portion of the vehicle, then the space below the seat is occupied by the rear shock absorber, but this makes it difficult to secure the arranging space for the ABS unit and the detaching operation becomes difficult
Solution Approach 1:
The bracket is divided into a main bracket member fixed to the frame and a sub-bracket member to which the ABS unit is attached. The sub-bracket member can be detached from the main bracket member, allowing the ABS unit to be removed without detaching the engine or other heavy components. This segmentation enables easy maintenance while maintaining proper mass distribution.
Solution Approach 2:
The two-divided bracket structure acts as an intermediary between the frame and the ABS unit. It provides a mounting interface that allows the ABS unit to be securely attached when needed and easily detached for maintenance, mediating between the need for secure mounting and easy access.
3Device complexity
If the valves and the hydraulic pumps are distributively arranged in different locations, then the hydraulic braking device can be distributed, but this takes time to perform the attaching operation and the brake piping becomes complicated
Solution Approach 1:
The ABS unit integrates the hydraulic pump and valves into a single assembled unit. This merging of components reduces the complexity of brake piping connections and allows the entire ABS unit to be attached as one package, significantly reducing the time required for installation and maintenance operations compared to distributing components separately.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration simplifies maintenance by allowing the ABS unit to be detached without removing the engine, enhances supporting strength and rigidity, and reduces the complexity of brake piping, making the system more efficient and easier to maintain.
Implementation Method 1
A brake operational force transmitted from the master cylinders to the hydraulic unit is amplified by the hydraulic unit and is transmitted to calipers of the hydraulic disc braking devices

AI summary
A motorcycle includes a main frame (41) having a pair of right and left frame members (41a, 41a), an engine (15) arranged below the main frame (41), and a hydraulic braking device. The hydraulic braking device has a hydraulic unit which incorporates a pump, e.g., an ABS unit (10), and the ABS unit (10) is arranged between the main frame (41) and a crankcase (18) of the engine (15) in the vertical direction, is arranged near one end in the vehicle width direction within the range surrounded by an outermost end line in the vehicle width direction of the main frame (41), and is attached to the main frame (41) so as to be detachable in the vehicle width direction. A bracket 50 preferably is divided into two members, i.e. a main bracket member (51) and a sub-bracket member (52).
