1. axle load distribution
axis load distribution (Distribution of Axle Load) is the ratio of the mass of cars assigned to the front and rear axles, generally expressed as a percentage, it is divided into two sets of full load and data. It is divided into two sets of data load and full load. Axle load distribution has been determined in the car after the shaping, the value which would normally be found in the manual.
axis load distribution in the vehicle design process generally take into account the following three aspects: uniform wear of the tire force, the main properties of the needs of the automobile, but also take into account the arrangement of the car.
theoretically ideal axle load distribution ratio of 50:50, the axle load distribution ratio to facilitate uniform tire wear, to ensure the car has better cornering characteristics and driving stability. Rear-drive (FR) vehicle due to the engine and the drive means are located at the front and rear part of the automobile, more easy to achieve load distribution shaft 50:50. Pre-precursor (FF) cars, the front axle axle load is preferably 55% or more, in order to ensure sufficient driving force uphill. The rear axle is twin 4×2 truck, a total of six tires, front and rear axle axle load should be the total mass of 1/3 and 2/3, respectively. After the rear-drive (RR) of the car, the rear axle shaft when loaded with more than 59 percentage charge should avoid overloading and tire uphill tipping backwards.
according to our requirements, equal to or less than the number of seats 9 passenger car, regardless of load and full load, axle load of the steering shaft which is not less than 30 percentage of the steering wheel in order to ensure a sufficient adhesion weight of the automobile maintain the stability of steering.
