| 摘要 |
<p>The invention relates to an appliance for traction while sliding between two surfaces that are in contact along a path of displacement, characterised in that it comprises a sliding surface, a structure for supporting independent rotating means, independent rotating means, at least one surface for applying the load, a support and levelling chassis, at least one start area, at least one end area, at least one sliding path, cavities, and control means, the sliding surface and the independent rotating means together receiving and splitting the traction force, at least once simultaneously, between the friction force generated by the sliding surface and the torque generated by the independent rotating means. The traction force has a continuous traction profile along the sliding path from the beginning to the end, optimally generating a desired movement profile with the desired control conditions, for the use of the appliance.</p> |
