Although there are many "engineering male" in the automobile industry, Mazda is one of them, and its persistence in developing new technologies is worth learning. No, fuel engines have been out of fashion for two years, and motors have gradually replaced them. Mazda immediately followed the rhythm and applied for a patent for a hybrid vehicle including a capacitor-driven hub motor: "Who said that we can only study engines? Motors can also be used. "
The system will be installed on vehicles with front and rear drive layout. The new car is equipped with two hub motors on the front axle, which are powered by capacitors; Behind the engine where the traditional gearbox is located, Mazda also designed a third motor, which is powered by a small lithium-ion battery.
In fact, here, Mazda uses a relatively simple physical principle, using the characteristics of high capacitor voltage to make the motor output power at a lower current. Therefore, the volume and mass of the motor can be reduced, and the burden brought by the existence of the motor to the control can be reduced to the maximum extent. The third motor located behind the engine can assist or directly drive the rear wheel, which is composed of 48V? 3.5kW lithium-ion battery pack, Mazda also designed a rear drive axle to better optimize the front and rear counterweights of the vehicle.
In this way, all-wheel drive is realized by three motors, but at present, this patent has not been officially carried on Mazda's existing models, and it is expected to officially debut in the future RX-9 coupe. (Article picture from the network)
