Opis:: The concept of a rail running gear is presented, with a friction – drum drive of the rail running gear rollers, designed for use in road-rail vehicles. The structure of the system and the distribution of forces in the load-bearing elements of the structure are presented. Comparative analysis of existing solutions are carried out. Future research directions in this field are proposed.
Zaprezentowano koncepcję szynowego układu jezdnego z bębnowym, ciernym napędem rolek szynowego układu jezdnego, przeznaczonego do zastosowania w pojazdach szynowo – drogowych. Przedstawiono strukturę układu oraz rozkład sił w elementach nośnych konstrukcji. Przeprowadzono analizę porównawczą istniejących rozwiązań. Zaproponowano dalsze kierunki badań w tej dziedzinie.

Opis:: Wyoming has one of the highest crash rates in the United States and a higher fatality rate than the U.S. average. These high rates result from many factors such as the high traffic through I-80 and the mountainous areas of Wyoming. This study employed two approaches to study contributory factors to crashes in the most hazardous interstate, I-80, in Wyoming by employing crash and citation data sets. Different factors may contribute to different driver actions so it is important to consider these crash causes separately. Thus, multiple logistic regression models were used in this study to examine the differences in crash-contributing factors for three driver actions: driving too fast for conditions, improper lane change, and no improper driving. These driver actions account for about 70% of all the crash causes on this interstate. The same violations as the two driver actions, improper lane change and driving too fast for conditions, account for 42% of all the crashes. The literature has indicated that previous violations can be used to predict future violations, and consequently crashes. Therefore, these violations were identified to detect the groups that are at higher risk of involvement in crashes. The analyses indicated that there are substantial differences across different driver actions for crash and violation data. For instance, not-dry-surface conditions increased the estimated odds of driving too fast for conditions 33 times while it decreased the risk of no improper driving by an estimated 250%. Crash severity, number of vehicles, vehicle maneuver, point of impact, driver condition, and speed compliance also impacted different driver actions differently. The results of violation analyses revealed that the interaction between types of vehicle and various variables were significant. For instance, nonresident truck drivers were more likely to violate all types of risky violations, which increased the estimated odds of crashes, compared with resident truck drivers. Recommendations based on the results are provided for policy makers to reduce high crash rate in the state.

Opis:: The paper is focused on presenting BLDC motor drive dedicated to road vehicle drive. Electric drive must fulfill specified functions depending on its application. Road vehicle drive sets particular demands higher than in case of other drives. Apart from obvious requirements common to all types of drives (such as starting or coasting), road vehicle drive should be able to recuperate energy during braking and to operate In reverse mode. The constructed test stand represents basic vehicle drive structure. The basic goal kept in mind during construction of test stand was selection of supply circuit structure (electronic commutator with auxiliaries). The paper gives detailed description of test stand with particular emphasis laid on the supply system structure and peculiarities of road vehicle.

Opis:: The article presents the issues of energy recovery in the hybrid drive system of a vehicle. Road tests of a vehicle equipped with a hybrid powertrain were carried out in accordance with the recommendations of the RDE test. In these studies, measurements of braking energy recovery were carried out in urban, rural and motorway traffic conditions. The analysis of the obtained test results may constitute a premise for the creation of an appropriate strategy for the operation of the hybrid drive system in terms of meeting the requirements of the currently prepared Euro 7 standard.
