Vehicular front axle powertrain which uses an electric motor with an external rotor

A process used by the vehicular front axle powertrain, the process:

• which uses an electric motor (1) with an external rotor marked by the external rotor or rotor extension (1.2) driving an internal joint (4), a shaft (5), an external homokinetic joint (6) and a hub shaft (6.2) to which a wheel of the vehicle is attached without any mechanical losses and is also driven by same mentioned elements when braking with the electric motor (1) which transmits braking kinetic energy into electric energy and accumulates this energy in a plurality of batteries;
• braking is also arranged to be carried out by a disc brake (3.1) mounted directly on an external part (3.Z) of a safety clutch (3), or by both principles together when braking torque exceeds 800 Nm which regulates a modem (M);
• the external rotor or rotor extension (1.2) is cooled through cooling fins (1.R) by water and by air and that heating energy is used to heat a vehicle cabin, for heating an internal combustion engine and the plurality of batteries;
• in case of crashing/blocking of the electric motor (1) and when the safety clutch (3) torque exceeds 800 Nm the safety clutch (3) disconnects the internal joint (4) from the electric motor (1);
• disconnection occurs due to torque in the safety clutch (3) which forces by pre-pressed steel balls (3.K) of a spring (3.V) of the safety clutch (3) to move out of a spherical bore (3.N.2) of the safety clutch (3) to the surface of the bore (3.N.2) causing a disconnect between an internal part (3.N) and the external part (3.Z) of the safety clutch (3);
• by reducing the torque in the safety clutch (3) the steel balls (3.K) slide back to the bore (3.N.2) and the connection is restored;
• the internal joint (4) allows the shaft (5) movement relative to the vehicle or stator (1.1) in a directions (SB) by an angle of (BK) in directions around the midline to the right (SD) and left (SL) while at the same time transmitting torques in the (SD) and (SL) directions;
• and
• an external pivot center (6.1) installed in the external homokinetic joint (6) enables the motion of the hub shaft (6.2) relative to the shaft (5) in a direction (SA) by an angle of (AK), while at the same time transmitting torques in the directions (SD) and (SL).
