The pulley method in the CVT is made of two pulleys, a single connected to the engine and the other to the transmission. The 2 pulleys are related by a belt or chain. The pulleys are shaped like cones, and their diameters is often altered to change the gear ratio.
CVT transmissions can final just given that classic transmissions If they're properly managed. On the other hand, they are often more expensive to maintenance if a thing goes Improper.
Not like typical CVTs, Daihatsu’s D-CVT doesn’t just depend upon belt drive, but introduces break up gears in to the blend.
