ATV Brake Modulator Mounting for Maintenance Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing all-terrain vehicles (ATVs) lack an efficient and accessible brake system design that allows for easy maintenance and optimal positioning for both front and rear wheels, compromising braking performance and accessibility.
Innovation Solution
The design incorporates a brake system with a brake modulator mounted to the front frame part and a master brake cylinder positioned on a lateral side, coupled with a non-boosted brake system featuring disc brakes for both front and rear wheels, and a method of assembly that includes separate tubular frame parts connected via frame joints, allowing for efficient coupling of wheels to the engine via drive units and strategic mounting of brake components for ease of access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the brake system components are mounted in a conventional centralized location, then the structural simplicity is maintained, but the accessibility for maintenance and optimal positioning for front and rear wheels is compromised
Solution Approach 1:
The brake system is segmented into separate mounting locations - the master brake cylinder is mounted on the frame near the driver for easy access, while the brake modulator is positioned to optimally serve both front and rear wheels. This segmentation allows each component to be positioned independently for optimal maintenance accessibility and functional performance.
2Reliability
If the brake modulator is positioned to optimize braking performance for all wheels, then braking performance is improved, but the accessibility for maintenance may be compromised
Solution Approach 1:
The brake modulator serves as an intermediary component positioned centrally to distribute brake fluid to all four wheels optimally, ensuring balanced braking performance. Meanwhile, the master brake cylinder is positioned as a separate accessible component near the driver, allowing maintenance personnel to easily service the system without compromising either performance or accessibility.
3Device complexity
If a non-boosted brake system is used to simplify the system, then the device complexity is reduced, but the braking power may be insufficient
Solution Approach 1:
The non-boosted brake system utilizes hydraulic pressure generated by the master brake cylinder to actuate the brake modulator, which in turn distributes pressure to all four wheel brakes. This hydraulic system provides sufficient braking force without requiring complex mechanical or vacuum boost mechanisms, maintaining system simplicity while achieving adequate stopping power.

AI summary
An all-terrain vehicle includes a frame including a front frame part and a separate rear frame part connected to the front frame part via frame joints. A surface is supported by one of the front frame part and the rear frame part. An engine is supported by the rear frame part and is positioned behind the seating surface. Front wheels operably coupled to the front frame part are drivingly coupled to the engine via a front drive unit. Rear wheels operably coupled to the rear frame part are drivingly coupled to the engine via a rear drive unit. A brake system is mounted to the frame and includes front wheel brakes and rear wheel brakes. The brake system further includes a brake modulator and a master brake cylinder operably connected to the brake modulator. The brake modulator is mounted to the front frame part.
