METHOD OF INCREASING ADHESION OF RAIL VEHICLE TO CANVAS BY CHANGING CONDITIONS OF CERTAIN AXIS (AXES) Russian patent published in 2020 - IPC B60T8/17 

FIELD: rail vehicles.

SUBSTANCE: present invention relates to a method of increasing the adhesion of a rail vehicle to a web by varying the conditions of a certain axis (axes), involving the following steps: - determination of possibility to provide increase in total braking force (F_Sum_B) (state A) by changing the steering wheel clamping value at least of unit (I) from actual initial wheel spinning (slp1) to forced wheel stubbing (slpFcd), and when detecting this possibility: - change in wheel bulldoging, at least on unit (I) from actual initial slippage (slp1) to forced slippage (slpFcd) by adjustment of controlled value of tightening force on this assembly (I), which changes friction between wheel and rail in subsequent units (II, III), - adjustment of the controlled value of the tightening force at the subsequent units (II, III) in order to establish the wheel clamping in these units (II, III), also changed due to change of the friction nature, again to the invariable control value of the initial slippage (slp1), wherein it provides in units (I, II, III) optimized braking forces (Fbr_I*, Fbr_II*, Fbr_III*), wherein is sum (F_Sum_B) of optimized braking forces (Fbr_I*, Fbr_II*, Fbr_III*) in nodes (I, II, III) after preceding stages of method (state B) is greater than sum (F_Sum_A) of previous braking forces (Fbr_I, Fbr_II, Fbr_III).

EFFECT: higher adhesion of rail vehicle with web.
