Abstract
The utility model discloses a mechanical automatic transmission. A power input part transmits power to a power output part through a centrifugal clutch; when the rotating speed of the power output part is lower than or reaches a set value, the centrifugal clutch suffers from separation and reunion and is used for disconnecting or transmitting high gear power between the power input part and the power output part; and the power input part also transmits slow gear power to the power output part through a slow gear transmission component in a manner that a slow gear can be exceeded by a high gear. The mechanical automatic transmission has the beneficial effects that when the rotating speed of the power output part reaches the set value, the centrifugal clutch suffers from mesh transmission by utilizing the rotating speed of the power output part to carry out high gear transmission; when the resistance is larger, as the rotating speed of the power output part is reduced, the centrifugal clutch separates, and the low gear drives, therefore, when a vehicle is started on the flat ground and downhill or uphill, a starting gear is automatically set; and the mechanical automatic transmission has the timely and direct characteristics and is quickly switched to the high gear under the condition that the vehicle is started on the flat ground, and the traveling resistance is smaller, so that the effects of energy conservation and consumption reduction are better.
