Automatic gear using centrifugal force

摘要

The automatic gear has a driven shaft (2), an oil pipe, and a coil (7) and valve unit (3) with rod assemblies (8). A spring (7) electrically pre-tensions the coil in conjunction with the valve unit. The rod assemblies rotate together with the drive shaft and transform the centrifugal force dependent on the rotational speed of the driven shaft into a linear movement, so that the coil moves against the spring tension and according to the linear direction of movement. The valve unit is positioned at one end of the driven shaft and rotates with it. The rod assembly consists of a first rod part (9) one end of which is joined to the coil`s outer end. At least two rod parts (12,12`) have one end joined to the outer end of the first rod part, and their outer end possessing a weight (11,11`).
