Another method of reducing load transfer is by increasing the wheel spacings. Some setup changes might apply, for example, CG might be lowered by reducing ride height, and track width might be increased by changing wheel offsets properly or using wheel hub spacers. The difference in height between the roll center and center of gravity of the sprung mass gives rise to a moment. Antiroll bars are generally added to the car to make it stiffer in roll without altering the ride characteristics. This will give: Now consider , the vertical load on the outer tyre in a corner, and , the vertical load on the inner tyre. This leads some to think that increasing roll centre heights will actually decrease weight transfer because it reduces roll. As we discussed, we should input consistent units into the equation to obtain meaningful results. Roll stiffness is defined as the resistance moment generated per unit of roll angle of the sprung mass, and it has SI units of Nm/rad. a Roll Stiffness & Weight Transfer - Balance Motorsport Weight transfer involves the actual (relatively small) movement of the vehicle CoM relative to the wheel axes due to displacement of the chassis as the suspension complies, or of cargo or liquids within the vehicle, which results in a redistribution of the total vehicle load between the individual tires. In a brief feedback after the first outing (a set of laps in a session) of the free practice session, the driver complains about excessive oversteer in these parts of the circuit. HOW MUCH IS ENOUGH? - Classic Motor Racing Club In order words, the goal would be to reduce lateral load transfer in the rear axle in comparison to the front axle. Racing Skills In 60 Seconds - Weight Transfer | Blayze The thing is, roll is only one part of the equation, and as the discussion on this post will show, increasing roll centre height might either increase or decrease the lateral load transfer, depending on other parameters. Trailer Towing Calculator: Weight Distribution Hitch When expanded it provides a list of search options that will switch the search inputs to match the current selection. Now do the same, but picking a front roll centre height and imagining a vertical line instead. Notice that this is just one possibility and other parameters might be investigated as well. How can weight shift when everything is in the car bolted in and strapped down? weight transfer - Everything2.com 26 Driving Techniques From The World's Best Race Car Drivers - HotCars If you hold rear roll rate distribution constant at 54 % and increase roll centre height, lateral load transfer will have no significant change.
