Abstract
The invention relates to a continuously variable automatic transmission that modifies the transmission ratio thereof by means of the accumulation and conversion of potential and kinetic energy. The transmission, which is functionally formed around a device accumulating elastic potential energy (6) with a controlled (7) output (2), has an inflow system (5) suitable for distributing the energy that is absorbed, and an outflow system (9) suitable for delivering the potential energy that has been absorbed and converting it into kinetic energy. The accumulator of elastic potential energy is formed around an elastic spiral spring, the inlet thereof being arranged so as to only allow the inflow of energy and the outlet thereof so as to control the energy delivery.
