Abstract
Summary. Existing theoretical calculations speeds in areas of horizontal and vertical curves designed for the needs of construction and calculation of cars and can not be used for valuation. When calculating the value of the coefficient of friction velocity determined at full wheel lock that does not correspond to the actual conditions of braking stability conditions of the car within its lane. The article proposes to calculate the permissible vehicle speed for the sites of horizontal and vertical curves on forest roads from the requirement car stop within the zone of visibility without buckling considering assumptions: during braking movement remains manageable, the driver keeps the car in the outside lane; magnitude of the angular velocity of the steering wheel is small; fully utilized inhibitory properties least loaded wheel; cornering power coefficient of resistance of tires depends little on the change of loads on the bus; low rolling resistance. Studied are normal reactions to the vehicle wheels when braking, namely found that if the friction coefficient on the road for less than the calculated optimal braking, the restriction on the braking occurs danger of losing control of the car skidding due to the front wheels. If the coefficient of friction on the road more than the calculated optimal braking, the braking force limitation occurs for blocking the rear axle. When comparing full stopping distance with the existing area of visibility is determined permissible speed.
