Individual-powered dual CVT differential system with stabilizing device

A individual-powered dual CVT differential system with stabilizing device, which is structured by that for the common load body (L100), the motor (M100) is installed to drive the wheel group (W100) placed at the load through the continuous variable transmission (CVT100) and the transmission (T100), and the motor (M200) is installed to drive the wheel group (W200) placed at the load through the continuous variable transmission (CVT200) and the transmission (T200), and the stabilizing device constituted by the torque limited coupling device with sliding damping during sliding is installed between the loads individually driven by the two CVTs of the motors, if the wheel group (W100) and the wheel group (W200) placed at the load are driven with speed differential, the continuous variable transmission (CVT100) and the continuous variable transmission (CVT200) automatically regulate the speed ratio with the load variation to coordinate with rotation differential between the wheel group (W100) and the wheel group (W200) at the load, and the stabilizing device stabilizes the operation between the loads individually driven by the two CVTs, in which:

• motors (M100), (M200):
• constituted by rotary motors, which are AC or DC, brushless or brush, synchronous or non-synchronous, internal or external rotation type;
• continuous variable transmissions (CVT100), (CVT200):
• related to continuous variable transmissions, which can automatically change the speed ratio according to the load state, or change the speed ratio in receiving external manipulation, including a variety of types, such as rubber belt type, metal belt type, and chain type CVT, or the electronic continuous variable transmission (ECVT), or the friction disk type, or the conventional iso-axis continuous variable transmission;
• stabilizing device (SDT100):
• constituted by dual-end shaft coupling device with the functions of setting coupling torque and sliding damping when exceeding the torque, including the stabilizing device with dual-end shaft structure formed by fluid viscosity effect, fluid damping effect, mechanical friction effect, or electromagnetic eddy current effect or power generation anti-torque effect, in which the two revolution ends individually link between the loads of the continuous variable transmissions (CVT100) and (CVT200), if unstable operation is caused by the varied load at individual load side during driving operation, the stabilizing device (SDT100) installed between the loads operates to stabilize the system;
• transmission (T100):
• related to fixed speed ratio, variable speed ratio, or stepless speed variable transmission, which is constituted by mechanical gear unit, sprocket unit, pulley unit, or linkage group;
• and the transmission is selectable as needed;
• and
• electric control unit (ECU100):
• constituted by the electric machine and/or the solid state power element, and/or the electronic element, and/or the microprocessor, and/or related software, for receiving the control of the user interface (MI100) and/or the central control unit (CCU100), wherein a motor drive control circuit is installed within the electric control unit (ECU100) for manipulating rotational speed, torque, rotary direction, and current of the parallel connected motors (M100) and (M200);
• or motor drive control circuits individually equipped to the motors (M100) and (M200) are individually installed within the electric control unit (ECU100) for individually manipulating rotational speed, torque, rotary direction, and current of the motors (M100) and (M200), which do not involve the close loop or semi-close loop rotational speed control between the two motors to achieve the speed differential function;
• the speed differential operation between the loads is through the continuous variable transmission installed between the individual motor and the load to perform speed difference regulation.
