Abstract

The invention provides a vehicle axle load determining method and a vehicle axle load determining device. The vehicle axle load determining method comprises the following steps: a step of acquiring a vehicle total weight M, a complete vehicle curb weight G, a vehicle inside full weight G1, a distance X between a barycenter of a driver and a central line of front wheels, a distance L between the front wheels and a center of a container, a wheel base D, and a no-load rear axle load Fr1; and a rear axle load determining step, namely a step of determining the rear axle load Fr during the full load of the vehicle according to the vehicle total weight M, the complete vehicle curb weight G, the vehicle inside full weight G1, the distance X between the barycenter of the driver and the central line of front wheels, the distance L between the front wheels and the center of the container, the wheel base D, and the no-load rear axle load Fr1. The vehicle axle load determining method is advantageous in that the rear axle load Fr during the full load of the vehicle can be determined according to the measurable parameters of the vehicle during the designing phase of the vehicle; by comparing with the prior art, the calculating method is simple, and the error rate is small; the rear suspension, the rear axle, and the tires, which are capable of satisfying the design requirements much better, can be selected accurately, and therefore the development time can be reduced, and the development costs can be saved.

Description

technical field [0001] The present invention relates to the technical field of vehicles, in particular to a method and device for determining the axle load of a vehicle. Background technique [0002] In order to meet the loading requirements of the vehicle design, it is necessary to calculate and distribute the rear axle load of the vehicle in the vehicle design stage, so as to select the rear suspension, rear axle and tires that meet the loading requirements. At present, in the design stage of the vehicle, the axle load of the rear axle of the vehicle under full load is generally determined by the following method: first determine the center of mass of the vehicle through the test method, and then calculate the axle load of the rear axle of the vehicle based on the determined center of mass of the vehicle ; but this method has the following defects: the error of the center of mass of the vehicle determined by the test method is relatively large, and the error of the axle lo...
