Abstract

One technical solution employed in electric cars is the positioning of an electric drive motor in the rim cavity. This solution results in excessive rim fatigue, impacts on the outer parts of the motor, excessive transfer of the weight of the car onto the two front wheels, and dirt entering the motor and its bearings, all of which are prevented with this invention. The invention consists of a substantially cylindrical body containing the electric motor and having a surrounding surface and two covers, a connection box being provided on the surrounding surface. The motor is coupled to the steering system at the upper or lower part thereof by means of an opening aligned with the fully sealed cover.

State of the art.
Existen el mercado y por tanto pueden considerarse como estado de la técnica distintos tipos de medios de tracción de vehículos automóviles, principalmente mediante los llamados motores de explosión bien sea de gasolina o diesel, y más recientemente los motores eléctricos, los cuales transmiten el giro de su cigüeñal o eje de giro, en el caso de los motores eléctricos, a un diferencial que convierte este giro en giro de las ruedas, bien sea de las delanteras en los llamados vehículos de tracción delantera, o bien en las traseras en los vehículos de tracción trasera .  There are the market and therefore can be considered as a state of the art different types of means of traction of motor vehicles, mainly by means of the so-called explosion engines either gasoline or diesel, and more recently electric motors, which transmit the rotation of its crankshaft or axis of rotation, in the case of electric motors, to a differential that converts this rotation into rotation of the wheels, either from the front in the so-called front-wheel drive vehicles, or in the rear in the vehicles of rear wheel drive
Un diferencial según es ya conocido, contiene como elementos principales un árbol de transmisión en uno de cuyos extremos se incorpora un piñón de ataque de una corona, que por los medios adecuados hace girar unos palieres en uno de cuyos extremos se une a la rueda por medio de la correspondiente mangueta. Las ruedas giran locas angularmente merced a la mangueta, a la vez que la misma forma parte de un conjunto de mecanismos que son los encargados de convertir el giro del volante de la dirección que lleva a cabo el conductor, en el giro angular de las ruedas . A differential as it is already known, contains as main elements a transmission shaft at one of whose ends a pinion of attack of a crown is incorporated, which by means of suitable means rotates some bearings at one of whose ends are attached to the wheel by means of the corresponding sleeve. The wheels rotate madly angularly thanks to the sleeve, while it is part of a set of mechanisms that are responsible for converting the steering wheel rotation carried out by the driver, in the angular rotation of the wheels .
También se conoce la aplicación del motor de tracción en la propia rueda quedando el mismo en el hueco interior de la llanta, por ejemplo la firma Michelin incluye en dicho hueco un motor eléctrico, junto con los sistemas de suspensión y frenos, dicho sistema de ha denominado Active Wheel y es la base del concepto Venturi Volage, y también la del ILL, construido conjuntamente por la firma Heuliez, fabricante especializado.  It is also known the application of the traction motor in the wheel itself being the same in the inner hollow of the tire, for example the Michelin firm includes in said hollow an electric motor, together with the suspension and brake systems, said ha system called Active Wheel and is the basis of the Venturi Volage concept, and also that of the ILL, jointly built by the firm Heuliez, a specialized manufacturer.
Otras firmas como la alemana Siemens ha desarrollado el sistema "VDO e Córner", que incluye en el hueco de la llanta el motor eléctrico de tracción, el motor eléctrico para la dirección, con un sistema de suspensión activa y frenos eléctricos.  Other firms such as Germany's Siemens have developed the "VDO e Corner" system, which includes the electric traction motor, the electric steering engine, an active suspension system and electric brakes in the rim.
Finalidad de la Invención. Purpose of the Invention
Prescindir del diferencial como medio de transmitir el movimiento de un motor eléctrico directamente a una sola rueda, lo que implica una modificación de los sistemas de dirección y tracción hoy en día en uso, tanto para los vehículos equipados con motor de explosión como los equipados con motor eléctrico, de manera que el motor eléctrico va directamente aplicado al eje de giro de la rueda previsto en la mangueta. Otro de los fines de la invención es posicionar el motor de tracción fuera del hueco de la llanta, con el fin de evitar la suciedad producida por la pisada de la cubierta de la rueda, fatiga excesiva de la llanta e impactos, y una mejor de distribución de pesos en el eje de giro, que será a la vez de tracción. Dispense with the differential as a means of transmitting the movement of an electric motor directly to a single wheel, which implies a modification of the steering and traction systems in use today, both for vehicles equipped with an explosion engine and those equipped with electric motor, so that the electric motor is directly applied to the axis of rotation of the wheel provided in the sleeve. Another of the purposes of the invention is to position the traction motor out of the tire gap, in order to avoid dirt produced by the tread of the wheel cover, excessive tire fatigue and impacts, and better Weight distribution on the axis of rotation, which will be both traction.
