Estimating the term…
The present invention relates to a coating and a frame for wheels. The coating has a hollow cylindrical configuration and extends radially between inner and outer portions. The outer portion acts as a tread element and confers the ability to maintain, in use, contact with the ground, to such coating. The inner portion defines a plurality of engagement elements. The frame comprises a hub, a crown and a supporting element which operates in connection between the hub and the crown. The crown is arranged peripherally with respect to the hub and acts as a support element for the coating when the coating is applied to the frame so as to externally encircle the crown. The crown defines a plurality of engagement elements. The engagement elements of the coating and the crown create an interference-type coupling between the coating and the frame, generating forces in the tangential direction.
A coating for wheels, said coating having a hollow cylindrical configuration and extending radially between an inner portion and an outer portion, said outer portion being configured to act as a tread element and conferring to said coating the ability to maintain, in use, contact with the ground, wherein said inner portion is configured to define a plurality of engagement elements, said engagement elements being configured to make an interference-type coupling between said coating and an element of a frame for wheels, such as to generate, between said coating and said element of said frame, forces in at least partially tangential direction.
A frame for wheels, comprising a hub, a crown and at least one supporting element, said hub being configured to be coupled to an axle of a traction system, said crown being configured to act as a support element for a coating for wheels when said coating is applied to said frame so as to externally encircle said crown, said crown being arranged peripherally with respect to said hub, said supporting element operating in connection between said hub and said crown and being configured to confer structural strength to said frame, wherein said crown is configured to define a plurality of engagement elements, said engagement elements being configured to make an interference-type coupling between said frame and said coating, such as to generate, between said frame and said coating, forces in at least partially tangential direction.
A mobile device configured to support and manage at least one payload, said at least one payload being rigidly and removably constrained to said mobile device, said payload being a cutting plate, wherein said mobile device comprises at least one wheel assembly, said at least one wheel assembly being rotatably constrained to an axle of a traction system of said mobile device, a bearing being interposed between said axle of said traction system and said hub of said wheel assembly,
