The time-sharing synchronous four-driving force assembly (hereinafter referred to as the four-driving force assembly) applies three core technologies, filling the gap in the time-sharing synchronous four-driving force in the field of pure electric vehicles at home and abroad.
One of the core technologies, automatic clutch:
Independent research and development, the world's first, adopts isometric cam centrifugal two-way automatic clutch technology, and is made through advanced precision manufacturing technology. Its key technology is dry environmental protection, positive and negative two-way, automatic clutch, which is the core component of the powertrain. Ensure that there is zero failure when driving 20W kilometers.

The second core technology, permanent magnet synchronous motor:
Adopting innovative research and development, domestic leading bidirectional V-shaped slanted groove permanent magnet technology, the radial and axial V-shaped arrangement between the stator and the rotor through the permanent magnet material, generating axial and radial magnetic flux, eliminating the axial resistance of the rotor , To realize the smooth running of the motor, improve the stability of torque output at high speed, and ensure the effective driving force of the vehicle at high speed.
|rated power(kW)||Peak power(kW)||Peak power density(kW/kg）||Peak torque(N·m)|
|Effective material quality(kg)||Efficient area（%）||Highest efficiency（%）||Weight(Kg)|
The third core technology, integrated structure, time-sharing synchronization:
The above-mentioned two input and output clutches and two motors of different powers are combined into an integrated structure powertrain, which can realize the flexible loading of front, middle and rear, and the switch between dual drive and four drive mode. ...
Mechanical synchronization realizes that the two motors coaxially output the same power, the same speed, and the same torque of the highly synchronized four-wheel drive power. The four-wheel synchronization can be guaranteed under any complicated road conditions. ...
Only a set of liquid cooling system is used, the layout is compact and reasonable, the installation cost is saved, and the maintenance is convenient.
