Analysis of Trailer Axle Load

Yang Beibei Kuang Liquan

Abstract：This article， through to the foreign well-known trailer axle company ADR product data analysis， puts forward a method of calculating trailer axle load analysis and a kind of trailer axle load calculation model and formulas. And by this method， the formula can be obtained under the condition of different specifications and axle speed accurately safety coefficient of axle load. At the same time， this paper also provides a series of different specifications of shaft tube load safety factors at the speed of 40km/h. The research and analysis of this paper can provide support for the design of trailer axles in the future and help improve the design ability.

Key words：trailer axle， safety coefficient， axle load
