Which is more than the car having front wheel drive, so far as gradability is concerned. Or just dive right in and try it for free below Take your first step to. Watch this 2-minute video introduction to the Axle Weight Calculator now, or see more info about the app on our Axle Weight Calculator page. Forces acting on a vehicle moving up a gradient. Calculate axle weight distribution and check bridge law compliance. TruckScience’s Axle Weight Calculator program produces Mass Distribution Sheets, which are a legal requirement for Whole Vehicle Type Approval of heavy goods vehicles in Ireland. If the coefficient of friction on the high way is 0.6, calculate the advantage of having rear wheel drive rather than front wheel drive as far as gradiability is concerned, if engine power is not a limitation.Ĭonsidering the car moving at constant speed up a gradient of angle 9, the forces giving equilibrium are shown in Fig. The wheel base is 3 m and the height of centre of gravity above ground above is 0.55 m. A car weighing 21336.75 N has a static weight distribution on the axles of 50:50. Forces acting on four-wheeled vehicle at rest.Įxample 31.5. Let Rf and Rr be vertical reactions at front and rear wheel respectively,įig. the reactions on both rear wheels are equal and also on both front wheels. Thus the problem is simplified by considering it as a two-wheeled vehicle i.e.
In this case only three independent equations can be formed to take care of four unknown viz., four reactions at the wheels. Gross Axle Weight Rating is the maximum amount of weight one axle can support. Forces acting on a four-wheeled vehicle at rest are shown in Fig. To calculate your vehicles towing capacity, youll need to know the full.
