Stepanov V. Reduction of the inequality of the braking torques on the wheels of a car

Research object: the processes that occur in brake mechanisms when both their parameters and control actions change, as well as an impact of the processes upon vehicle road holding while braking. Research objectives: to enhance the braking properties of a car; and to increase road holding during braking due to the decrease of the inequality of braking torques on one axis wheels. Research methods: the system analysis methods, the differential equations methods, the theory of similarity methods, methods of bench-top and full-scale experiments are used Theoretical and practical results: the given equations allow evaluating vehicle road-holding during braking, the application of the designed system allows advancing to a new level of car braking system development. Novelty: it is the first time when new relations have been fed into a physical model of front braking mechanisms. The further development of the physical model of a vehicle disturbed motion during braking is carried out. New relations between braking system constructive parameters, that provide effective operation of a braking torques inequality decrease system on front wheels, are calculated. Implementation: the developed in the dissertation method to decrease braking torques distribution inequality is accepted to be applied by the engineering department of the joint venture closed joint-stock company "Avtozaz-Deu" and the institute of machines and systems of Minprompolitika of Ukraine and the National Science Academy of Ukraine. Field of application: motor-car construction.
