Embodiment Construction

[0020] Referring to the drawings, a motorized wheel according to the invention is indicated generally by the reference numeral 10 .

[0021] The motorized wheel 10 is of the type comprising an electric motor 11 , for example but not exclusively a direct current motor, supported by a fixed support 12 and adapted to be driven by rotation rate reducing means 13 , and an internal hollow wheel 14 . Supported in rotation, the inner hollow wheel is profiled to partially house the electric motor 11 and the rotation rate reducing means 13 .

[0022] The electric motor 11 comprises a stator housing 15, for example but not exclusively, which supports a plurality of permanent magnets, and a dome 16, such as a brush holder dome, and a rotor, which is located in said stator housing. 15, only the shaft 17 of the rotor is shown for the sake of simplicity.

[0023] The motorized wheel 10 according to the invention is characterized in that the stator casing 15 is inserted into a corresponding ...

Abstract

The invention relates to a motorized wheel (10) comprising an electric motor (11) and a hollow internal A motorized wheel of the type of wheel (14), the electric motor being supported by a fixed bracket (12) and adapted to be rotatably supported by a rotation rate reducing means (13), the internal hollow wheel profile being configured to at least partially accommodate said An electric motor (11) and said rotation rate reducing device (13), said electric motor (11) comprising a stator housing (15), a dome (16) and a rotor located inside the stator housing (15), the stator housing (15) is inserted into a corresponding complementary shaped annular portion (18) extending from the bracket (12) and secured thereto by an interference fit. The motorized wheel of the present invention is easy to assemble, can significantly reduce assembly time, and allows controlling the radius of curvature of the motorized wheel in a very flexible manner.

Description

technical field [0001] The invention relates to a motorized wheel. Background technique [0002] Currently, floor scrubbing machines, industrial sweepers, electric trucks for transporting goods in warehouses are usually provided with a plurality of so-called motorized wheels. [0003] figure 1 is a cross-sectional view of a conventional motorized wheel, designated by the reference letter A. [0004] The motorized wheel A comprises an electric motor B, for example but not exclusively a DC motor, supported by a fixed bracket C for securing the motorized wheel to a truck or scrubber Or the structure of another machine comprising the motorized wheel; the electric motor B is adapted to be rotated by a rotation rate reducing device D, the internal hollow wheel E being contoured to at least partially house said electric motor B and the rotation rate reducing device D; As known, the electric motor B comprises a stator housing F supporting a plurality of permanent magnets, a brush...
