For ease of fit in the curves of the track sections, these carts have 11 mm transverse stroke of the wheel pair
relative to the sidewall.
Adhesion is a phenomenon caused by the rolling wheel pair
subjected to a tangential traction, where the rolling pressure leads to deformation between the wheel and the rail as well as the continuous and stable contact surface between the wheel and the rail.
For a solution of the problem of dynamic interaction of wheel pair
and rail gauge, the authors have proposed a block construction of the wheel set, which main feature is an independent rotation all surfaces their wheels contacting with surfaces of track rail.
Drugs were laid in the cache, which was located in wheel pair
of the wagon, according to the press service.
Under such conditions, the wheel passes to compact contact with the rail and flange wear sharply slows down and takes place when both flange and the profile of the roll surface wear at the same time; mostly it gets to condemn the thickness of a wheel pair
of flange 'B'.
1:p of new wheels equals to 1:20, and 1:p reaches 1:100, 1:200 and even more as wheels wear; [rho] is the radius of the wheel rolling circle, R--the curve radius, c--distance between side edge of rail head to axis, a--the distance between internal wheel pair
flanges at altitude of where gauge width is measured and b--the flange thickness at altitude in the place where gauge width is measured.
To prevent spread of the weld pool and save welding consumables in surfacing, the wheel pair
was inclined at the angle not less than 5[degrees] to horizon in such way that the wheel profile to be parallel to horizon .
According to Russian railways, the whetting with primal inductive heating is already effective with the whet 2.5-3 thousand wheel pair
Here the design must provide for the formation of a contact between wear-prone surfaces, and the condition of the wheel pair
is difficult to predict.
