Motorcycle ABS Module Placement Above Crankcase
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional motorcycle ABS modules are vulnerable to damage from mud, stones, and road collisions, and their placement below the radiator can degrade cooling performance by requiring a reduction in radiator volume.
Innovation Solution
The ABS module is positioned below the suction pipe and fuel supply device, behind the engine's cylinder assembly, and above the crankcase, allowing it to be protected from shocks while maintaining a compact and slim body design without reducing the fuel tank or radiator volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the ABS module is disposed at the front lower portion of the vehicle body, then it is protected from road surface collision, but mud and stones bounced up by the front wheel may damage the ABS module
Solution Approach 1:
The patent relocates the ABS module from the conventional front lower position to a new spatial position above the crankcase and behind the cylinder assembly. This dimensional relocation in the vertical and longitudinal axes removes the module from the direct path of mud and stone projection while maintaining protection from road surface collision through the engine structure.
2Volume of moving object
If the ABS module is disposed below the radiator, then space utilization is improved, but the radiator volume must be reduced which degrades cooling performance
Solution Approach 1:
The patent utilizes the vertical space above the crankcase and behind the cylinder assembly, a dimension that was previously underutilized. This allows the ABS module to be positioned without encroaching on the radiator's horizontal space, thereby maintaining full radiator volume and cooling performance while achieving compact overall vehicle dimensions.
3Ease of manufacture
If the ABS module is positioned in the conventional location, then installation is simplified, but the motorcycle body cannot achieve compact and slim design
Solution Approach 1:
By positioning the ABS module in the vertical space above the crankcase rather than in the conventional front lower horizontal space, the patent enables a compact and slim motorcycle body profile without complicating the installation process, as the new location provides adequate mounting surfaces on the engine structure.

AI summary
A motorcycle includes a front frame configured by connecting a head pipe, frame, down frame, and lower frame in a loop shape. The motorcycle also includes a rear frame, an engine disposed inside the front frame, an air cleaner disposed inside the rear frame, a suction pipe and fuel supply device connected to the air cleaner and supply gas to the engine, an ABS module controlling locking of wheels at the time of braking, and a cross member bridged between the right and left main frames at the rear portion of the front frame. The suction pipe and the fuel supply device are provided to pass on the upper side of the cross member; the ABS module is disposed below the suction pipe and the fuel supply device is disposed behind a cylinder assembly of the engine and above the rear portion of the crankcase.
