Tarasov Y. The improvement of working character istics of motor-cars by the improvement of the brake block choice method

The Object of the study: track record of car braking and processes, occurring on the surface of friction of front and back brake mechanism of passenger cars under different combination of friction pairs. The purpose of the study: the improvement of passenger car active safety on account of improvement of friction pair choice methods in the process of usage. Methods of study and equipment: theoretical and experimental methods of study have been applied in the given work. Theoretical and practical results: methods of distribution of brake power between axises of the car with provision for transmission revolving masses have been offered; the analysis of influence of brake bracket combinations with different characteristics on front and back axises of passenger car on brake power distribution; methods of rational choice of friction pair of front and back car brake according to temperature features has been developed. Actual value: the intercoupling between friction features of friction materials, brakepower distribution between the axises and brake characteristics of the car under round-robin brakings has been determined; physical model, allowing to realize the choice of friction pair of front and back brake mechanisms according to their thermalphysic feature has been designed; statistical features of emergency process of car braking, allowing to determine the distribution of brake power and braking efficiency have been obtained. Introduction degree: department of Machine Institute and Minprompolicy systems and NAS of Ukraine; Kharkov SDI of judicial expert after Bokarius. The Range of usage: car transport and car industry.
