Abstract
A method for speed control of railway transport facilities and a device to accomplish the method are used for deceleration and acceleration of transport vehicles in shunting yards. In the process of speed control a pressure element is introduced into an annular space cavity in a wheel, which cavity is formed by the disk hub and inner circular surface in the wheel rim, and is located on the inner or outer side of the wheel, said pressure element applies force action to any point located within one of the two inner circular wheel rim surface regions, located at both sides of an imaginary plane 'a-a', passing through the axle of the wheel and through the wheel-to-rail contact point B. The pressure element has a shape designed to provide free entrance of the element into said annular cavity, which pressure element is mounted on a carriage, the carriage being movable along the track. The value of the pressure element force in this solution will not be limited to the weight of a wagon.
