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 adhesion weight of the self-propelled vehiclevehicle.

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 according to 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 field of application of traction devices with automatic regulation of drive wheel pressure on the rail have shown that mechanisms with elastic slip 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.).

As a result of the study of traction devices, a new, most appropriate design of a peripheral drive for pulp thickeners has been developed.
