When a traction device operates on a circular rail, there is a more complex relationship of external and internal forces associated with the geometric parameters of the mechanism. ...
In the creation of efficient and economical vehicles for the mining industry, a significant place is given to traction devices that automatically adjust the pressure of the drive wheels on the rail depending on the realized traction force. One of the main advantages of these mechanisms is that the traction force in the interaction of the wheels with a smooth rail is created independently of the coupling weight of the self-propelled crew.
In order to ensure the optimal mode of operation under any conditions, traction devices with unstable transmission ratio are equipped with a relay tracking system, which operates on the deviation of the set angle and maintains the calculated value of the transmission ratio. It consists of a control object and an automatic regulator.
Studies of the application area of traction vehicles with automatic regulation of drive wheel pressure on the rail showed that mechanisms with elastic sliding can be used not only in the creation of vehicles (self-propelled skips and locomotives), but also in the design and construction of new friction drives for rotating parts of large units (cement kilns, mills, scrubbers, reactors, etc.).
