In the article local repair automobile tires expediency by vulcanization means in mechanical damage carcass case is shown. It has been established that analytical and experimental data on determining the required temperature of the heating element have a significant discrepancy. It was found that on the vulcanization degree among all factors temperature and pressure on the welding surfaces are the most influential. After processing the experimental data and using the static methods, mathematical dependence of the temperature on the welding surface from the heating element temperature and on the welding surfaces as a second-degree polynomial is obtained. In order to verify the research results reliability, the control welding of the automobile tires with cord lateral rupture was conducted, which gave positive results.
Influence streamlined elements located on the roof of the tractor main train such as the efficiency of the vehicle with installed no bonnet on it an advanced roof rack, which has the ability to adjust to any trailed warehouse. It has been assumed that it provides high levels of accuracy with respect to analogues due to the possibility of choosing the appropriate geometric parameters, provides ease of use and the ability to adjust the cushion during vehicle movement, prevents probable malfunctions during strong winds or hurricanes due to the strength of the drive management and modern electronic systems mechanical design. On the basis of theoretical studies of the main motor trains various tractors flow, the dependences of power and fuel consumption on the air traffic vehicle coefficient have been established at its movement speeds. It has been proven that it is advisable to use an advanced racing hub on precision drum trucks with small and medium-height cabs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
