Belt Driven CVT – Hybrid Transmission
Patent validity till 2037
This invention is a first of its kind belt driven hybrid transmission incorporating three pulleys instead of two pulley system. Two out of three pulleys connect to two independent power sources i.e., fuel engine and electric motor while the third is the output pulley that drives the vehicle. This allows for adding up the torque and power from fuel engine and electric motor while applying the gears independently to fuel engine and electric motor. These power sources can be driven at different RPMs to enable them to simultaneously deliver their peak power/efficiency.
This transmission mechanically combines the maximum torque from fuel engine and maximum torque from electric motor simultaneously even at lower speeds providing a much higher overall torque as well as fuel efficiency.
Another advantage of this system is the AWD capability. The pulley that draws power from electric motor, also acts as output pulley, and hence it becomes input-output dual purpose pulley. This way the dedicated output pulley connects to the first differential connected to one axle while the input-output dual purpose pulley connects with second differential which further connects to second axle. The designated clutch mechanisms on either side of the transmission allow the vehicle to switch between normal driving mode and AWD driving mode. These various aspects of transmission’s capabilities are described in detail in the patent.
