IMPROVING ABILITY OF ALL-WHEEL-DRIVING TRANSPORT FOR OVERCOMING OBSTACLES AS RECTANGULAR LEDGE
Are analyzed available in textbooks about the car-theory a formulas for calculation of the maximum height of the rectangular ledge overcome by wheels of the biaxial four-wheel drive vehicle and opportunity at some ratios of axial loads of overcoming is proved by front wheels of a threshold ledge which height will be equal to the radius of a wheel and even to surpass its radius. The conclusion that the major factor influencing abilities of a wheel (and a car axle) to overcoming of a single obstacle is weight load on this wheel (axle) is drawn.
