How does a CVT achieve reverse gear?

[SanFrancisco]

R gear is the reverse gear, and a CVT transmission has a planetary gear set placed at the input or output end of the continuously variable transmission mechanism. By controlling this planetary gear set, the switching between P, R, N, and D gears can be achieved, enabling reverse gear. Information about CVT is as follows: 1. CVT usually refers to a type of automotive transmission, also known as a continuously variable transmission. The difference between a CVT and a stepped transmission is that its gear ratio is not a series of discrete points but a continuous range of values, resulting in excellent fuel economy, power performance, and smooth driving experience, while also reducing emissions and costs. 2. In a CVT transmission system, traditional gears are replaced by a pair of pulleys and a steel belt. Each pulley is actually a V-shaped structure composed of two conical discs. The engine shaft connects to the small pulley, which drives the large pulley via the steel belt.
