MOTOR-REDUCER WITH INTEGRATED BRAKE AND INVERTER FOR DIRECT TRANSMISSION TO THE WHEEL OF AN ELECTRICALLY DRIVEN VEHICLE

摘要

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

1. Gear-motor with integrated brake for direct drive to the driving-wheel of an electric-traction vehicle where a traction motor is integrated with a gear-reducing device connectable to said driving-wheel of said electric-traction vehicle in correspondence with a hub, where said gear-reducing device is housed into a structural supporting box connectable to said electric-traction vehicle by means of fixing holes, said traction motor having its own supporting shell which is fixed as a cover to said box, said box and said cover constituting a single structural supporting casing of said gear-motor, said cover covering and encompassing said gear-reducing device within said box, the opening of said cover allowing the free access to said gear-reducing device on one side and to said motor at the opposite side characterised in that said traction motor is a motor whose transmission shaft is coupled in correspondence of a first pinion of said gear-reducing device or it is integral with said first pinion of said gear-reducing device and further characterised in that it includes an inverter intended to control said motor, said inverter being housed at the closing head of said motor, the driving and control wiring between said inverter and said motor having a minimum length which is given by the small distance between said motor and said inverter which is housed at the closing head of said motor, the driving and control wiring of said gear-motor by means of controls coming from said electric-traction vehicle comprising power supply cables for said inverter connected to feeding connectors and a control cable connected to a data line connector of said inverter.
