Embodiment Construction

[0040] Referring to the drawings, a geared motor with an integrated brake and inverter for direct drive wheels according to the present invention may comprise a single body comprising a gear reduction device (50), a motor (24), a brake (49), an inverse Transformer(32)( figure 1 , Figure 7 , Image 6 , Figure 5 ). A compact and resistant technical solution is thus obtained, with all the advantages offered by an integrated compact unit. Advantageously, the housing (34) of the geared motor comprises a first housing and a second housing formed in one piece, the first housing being the cover (16) and the second housing being the frame-like part (7); or the housing (34) containing the motor (24) and a gear reduction device (50) which becomes the main part of the transmission. This technical solution advantageously enables full access to the gear motor, since by removing the housing (34) the gear motor is easily opened in two parts, on the one hand showing the gear reduction d...

Abstract

Gear-motor (51) with integrated brake (49) for direct drive to the driving-wheel (27) of an electric - traction vehicle where a traction motor (24) is integrated with a gear- reducing device (50) connectable to the driving-wheel (27) of the electric - traction vehicle in correspondence with a hub (1), where the gear- reducing device (50) is housed into a structural supporting box (7) connectable to the vehicle by means of fixing holes (52), the traction motor (24) having a supporting casing fixed to the box as a cover (16), the box (7) and the cover (16) constituting a single structural supporting casing (34) of the gear-motor (51), where the traction motor (24) is a motor (24) whose transmission shaft is coupled in correspondence of a first pinion of the gear- reducing device (50) or is integral with it and where the motor control inverter (32) is housed in correspondence of the closure head of the motor (24).

Description

technical field [0001] The present invention relates to a geared motor with integrated brake and inverter with direct transmission to the wheels of an electric traction vehicle according to the features of the preamble of claim 1 . [0002] An electric traction vehicle with said geared motor with integrated brake and inverter is also part of the invention according to the features of the preamble of claim 22. Background technique [0003] In the field of motion transmission to the drive wheels of vehicles, especially industrial vehicles such as tractors, forklifts, or operating machines, electric or hydraulic motors are often used. [0004] The motor is usually associated with a mechanical gear reduction device that transmits motion to the wheels. [0005] These gear reduction devices, which exist in a compact structure, are called axles, which distribute the torque supplied by a single motor to the two wheels by distributing differential groups. Other axle configurations ...
