The previous releases of this regulation are. --- JJG 1014-2006. Verification Regulations for Special Shaft (Wheel) Weight Apparatus for Motor Vehicle Inspection1 ScopeThis regulation applies to the first inspection of the axle (wheel) weight instrument for motor vehicle inspection [hereinafter referred to as the axle (wheel) weight instrument] Inspection, follow-up inspection and inspection in use.2 Reference documentsThis regulation refers to the following documents. JJG 99 weight JJG 555 General Verification Regulations for Non-Automatic Scales GB 7258 Motor vehicle operating safety technical conditions GB 21861 Motor vehicle safety technical inspection items and methods For dated references, only the dated versions are applicable to this Regulation; for those without dates The latest version (including all amendments) is applicable to this regulation.3 Terms and units of measurement3.1 Terminology 3.1.1 Loadreceptor It is used to accept the load (such as load table), when adding or removing load on it, the shaft (wheel) The balance of the instrument will change. 3.1.2 Axle (wheel) load scales for kerb weight measuring That is, a special axle (wheel) weight meter for testing motor vehicle curb quality. Note. This type of axle (wheel) weight meter has sufficient effective measurement length, which can withstand the double-side and triple-side of the motor vehicle and install the same-side wheels on the shaft At the same time loaded on a carrier. 3.1.3 Axle (wheel) load measuring device loadingmethodautomobilebraketesters That is, the part of the measuring equipment used to detect the load quality of the automobile axle (wheel). 3.2 Unit of measurement The unit of measurement used by the axle (wheel) weight meter. kilograms (kg).4 OverviewAxle (wheel) weight meter is a kind of weighing vehicle axle load (or wheel load) to determine the motor vehicle Instruments for the distribution of axle loads (or wheel loads) can be divided into axle load gauges and wheel load gauges. The axle (wheel) weight gauge is generally made up of Carrier, weighing sensor, weighing display and other components. The load of the shaft (or wheel) on the carrier, through The load cell is converted into an electrical signal, and the weighing result is displayed on the load display. Axle (wheel) weight meter also includes loading brake Inspection table shaft (wheel) load measuring device, curb weight shaft (wheel) weight meter, motorcycle wheel weight meter. ...... |
