Abstract (en)
[origin: WO0000360A1] Enhanced traction control is provided in a modified 6x2 vehicle. An air suspension assembly is tied to the antilock/traction controller. Thus, in response to a differential traction control event, pressurized air to air bags associated with the suspension assembly is regulated to transfer greater vehicle load to the drive axle (10). This provides improved traction capability. If the drive axle is already at its rated maximum vehicle load, then no additional weight is transferred. In addition, isolation valves (72) are added to the brake lines associated with the non-drive axle (12). The isolation valves also communicate directly with the antilock/traction controller so that braking to the non-drive axle is isolated from the drive axle. This eliminates brake drag on the non-drive axle during a differential traction control event.
