Abstract :
In the article researches of increase of strength of motionless connections of wheeled and caterpillar cars due to use of cylindrical landings with a contour connection of details are resulted. The technique of designing and technological support of the connections possessing a number of operational advantages is developed. It has been shown by calculation and experimentation on a concrete example that a loop connection can significantly increase the strength compared to standard types with an interference fit.
