GB/T 15704-2025 Road vehicles - Light alloy wheels - Impact test method English, Anglais, Englisch, Inglés, えいご
1 Scope
This document specifies a laboratory test procedure to evaluate the axial (lateral) kerb impact collision properties of a wheel manufactured either wholly or partly of light alloys.
It is intended for passenger car applications, and special vehicle applications where there is a possibility of the wheel impacting the kerb.
2 Normative references
The following normative documents contain provisions which, through reference in this text, constitute provisions of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
ISO 3911 Wheels and rims for pneumatic tyres - Vocabulary, designation and marking
Note: GB/T 2933-2009 Wheels and rims for pneumatic tyres - Vocabulary, designation and marking (ISO 3911:2004, IDT)
3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 3911 and the following apply.
4 Test equipment
4.1 New wheels, fully processed, representative of wheels intended for vehicle application, fitted with a tyre. Tyres and wheels used in the tests should not be used subsequently on a vehicle.
4.2 Impact loading test machine with a vertically acting steel striker having an impacting face, in accordance with Figure 1. The striker mass, m, within a tolerance of ±2 %, expressed in kilograms, shall be as follows:
m=0.6W+180 (1)
where,
m - the mass of the striker, kg;
W - the maximum vertical static load which is specified by the wheel or the vehicle manufacturer, expressed in kilograms. In the absence of such specification, the largest value of the load rating of the tyre which can be applied to the wheel for the application.
4.3 Mass of 1000 kg.
5 Calibration
Ensure, by means of a test calibration adapter, that the 1000 kg mass applied vertically to the centre of the wheel fixing as shown in Figure 2 causes a deflection of 7.5 mm±0.75 mm when measured at the centre of the beam.
