What is curb force for a driven wheel?

When designing a new vehicle or a new powertrain and driveline, the ability of the vehicle to climb a curb (kerb) must be taken into account as initial requirement. Curb climbing is the ability of the vehicle to climb a curb, from standstill, with the wheel in contact with the curb. The case in which there is not traction force generate at the wheel, instead the wheel is pushed through the wheel hub; this is the case in which the vehicle is rear-wheel drive and the curb is climbed by the front wheel
