Geltungsbereich und Anwendbarkeit
This standard specifies the braking performance requirements and testing methods for motorcycles and mopeds. It is applicable to various categories of L-class vehicles, including two-wheeled and three-wheeled types. This standard does not apply to vehicles designed for disabled individuals. It serves as a mandatory regulation for manufacturers targeting the Chinese market.
Technische Anforderungen
The standard outlines the functional and characteristic requirements for different braking systems, including service braking systems, secondary braking systems, and parking braking systems. It mandates specific configurations based on vehicle categories, such as independent, combined (CBS), or split service braking systems. Manufacturers must ensure that vehicles meet the specific system configurations required for their vehicle class. For certain high-displacement two-wheeled motorcycles (L3 category), the standard mandates the installation of Anti-lock Braking Systems (ABS) or Combined Braking Systems (CBS). Specifically, motorcycles with an engine displacement greater than 250mL must be equipped with ABS on both front and rear wheels. This requirement is a critical compliance point for high-performance motorcycle manufacturers. The standard also sets strict requirements for brake master cylinders, warning lights, and friction linings. For instance, friction lining materials must not contain asbestos, and warning lights must be installed to indicate ABS or split braking system failures. These component-level requirements ensure long-term safety and reliability. Performance requirements are detailed across various scenarios, including dry, wet, and high-speed braking conditions, as well as system failure modes. The standard specifies limits for stopping distance and mean fully developed deceleration (MFDD) under these conditions. Compliance with these performance metrics is mandatory for type approval.
Prüfverfahren
The standard defines a comprehensive series of testing procedures, including: - Dry braking tests: Conducted with both single and simultaneous control manipulation. - High-speed braking tests: For vehicles with a maximum speed exceeding 125 km/h. - Wet braking tests: Evaluating performance under continuous water spray. - Parking braking system tests: Assessing stability on an 18% gradient. - ABS tests: Including high/low friction surface tests and transition tests. - Failure tests: For split, power-assisted, and combined braking systems. - Fade tests: Evaluating braking performance after repeated thermal stress. - Peak Braking Coefficient (PBC) determination: Methods to assess road surface friction.
Häufige Fragen
What products are regulated under GB 20073-2018?
GB 20073-2018 regulates the braking performance and testing methods for motorcycles and mopeds, covering various L-category vehicles. This standard does not apply to vehicles designed for disabled individuals.
Are there mandatory ABS requirements under this standard?
Yes, for two-wheeled motorcycles (L3 category) with an engine displacement greater than 150mL, ABS or CBS is mandatory. For displacements over 250mL, ABS must be installed on both front and rear wheels. This requirement has a specific implementation transition period ending in 2020.
What are the key implementation dates for GB 20073-2018?
New type approvals must comply from July 1, 2018. From July 1, 2019, all new and previously approved models must meet the standard. Specific ABS requirements for L3 vehicles have a transition period until July 1, 2020.
