Overview
The JB-150 Motorcycle Brake Distance Marking System is a precision-engineered field-testing instrument designed to objectively quantify braking performance during motorcycle type approval and production line verification. It operates on the principle of synchronized optical marking and kinematic event capture: at the precise moment the brake actuation signal is detected (via pedal force transducer or hydraulic pressure sensor input), the system triggers a high-visibility, non-contact ink spray onto the roadway surface. A second mark is automatically generated upon full vehicle stop—enabling direct, traceable measurement of total stopping distance under standardized test conditions (e.g., ISO 7170, ECE R78, GB 17354). Unlike manual tape-based methods, the JB-150 eliminates human reaction latency and measurement parallax, delivering repeatable, auditable results essential for regulatory compliance and internal quality control.
Key Features
- Real-time dual-point marking: Simultaneous spray activation at brake initiation and vehicle standstill—ensuring temporal fidelity to ISO-defined braking event boundaries.
- Modular mounting architecture: Adaptable rail-and-clamp assembly compatible with standard motorcycle test rigs and open-road test tracks; no permanent vehicle modification required.
- Calibrated pneumatic ink delivery: Solvent-resistant, rapid-drying pigment formulation optimized for asphalt and concrete surfaces; consistent droplet size and impact geometry across environmental temperatures (−10 °C to +45 °C).
- Integrated trigger interface: Supports analog voltage (0–5 V) and digital TTL inputs from OEM brake sensors, ABS controllers, or third-party data acquisition systems (e.g., Dewesoft, National Instruments).
- Ruggedized aluminum housing: IP54-rated enclosure with shock-absorbing mounts; designed for repeated transport between factory test lanes and certification laboratories.
Sample Compatibility & Compliance
The JB-150 is validated for use with all two-wheeled motorcycles and mopeds with wheelbase lengths between 1.1 m and 1.6 m, including scooters, naked bikes, and lightweight off-road models. It complies with the physical test methodology requirements of GB 17354–2022 (Safety Requirements for Motorcycle Braking Systems), ISO 7170:2021 (Motorcycles — Braking Performance — Test Methods), and ECE Regulation No. 78 (Uniform Provisions Concerning the Approval of Motor Cycles with Regard to Braking). While the JB-150 itself is not a certified measuring instrument per OIML R 117, its output—when used in conjunction with NIST-traceable tape measures or laser distance meters—supports metrologically defensible reporting under ISO/IEC 17025-accredited testing protocols.
Software & Data Management
The JB-150 operates as a hardware trigger module without embedded firmware or onboard data storage. Its design prioritizes interoperability: raw trigger timestamps and status flags are output via RS-232 or opto-isolated digital I/O for integration into existing laboratory data acquisition environments. Users commonly synchronize JB-150 mark events with high-speed video (≥240 fps), inertial measurement units (IMUs), and brake line pressure loggers using common timebases (e.g., PTP IEEE 1588). All marking events are logged with UTC timestamps and annotated in CSV format for downstream statistical analysis in MATLAB, Python (Pandas), or Minitab—supporting trend analysis, SPC charting, and GLP-compliant audit trails when paired with validated LIMS platforms.
Applications
- Final assembly line brake verification prior to vehicle release.
- Brake pad compound development trials under controlled thermal load cycles.
- ABS calibration validation across varying road friction coefficients (μ = 0.3–0.9).
- Regulatory homologation testing for domestic and export markets (CNCA, JIS, DOT).
- Root cause analysis of brake fade during endurance testing (e.g., 10× stop-from-60 km/h cycles).
FAQ
Does the JB-150 require calibration certification?
No—calibration is performed externally using traceable length standards. The system’s accuracy specification (±1% F.S.) assumes user-provided measurement tools meet ISO 17025 requirements.
Can the JB-150 be used on wet or icy surfaces?
Yes—ink formulation adheres reliably to damp asphalt; however, stopping distance interpretation must follow ISO 7170 Annex B for low-friction conditions.
Is operator training required?
Minimal: Installation and trigger setup require <2 hours of guided instruction; no specialized certification is mandated.
What maintenance does the system require?
Quarterly nozzle cleaning with isopropyl alcohol; annual inspection of pneumatic seals and mounting hardware torque values.
Is the ink residue hazardous or difficult to remove?
No—the water-based, non-toxic pigment washes off with standard road cleaning equipment and leaves no permanent staining on cured asphalt or concrete.
