planetary gears to combine their outputs instead of a belt used in traditional CVTs. A notable example is the Toyota Hybrid Synergy Drive. Friction-disk transmissions
variable transmissions or capable of acting as such as well. They include the pendulum-based Constantinesco torque converter, the Lambertfrictiongearing disk
further with drive-train technology, and devised the Lambertfrictiongearingdiskdrivetransmission, which became a key feature on all of his future automobiles
or a rotor to create friction. There are two basic types of brake pad friction mechanisms: abrasive friction and adherent friction. This action slows the
