Abstract

The invention provides a mechanical continuously variable transmission method involving a dual planetary mechanism and a continuously variable transmission mechanism. The continuously variable transmission mechanism comprises two planetary groups which are connected together in series. Through the multi-gear or multi-chain connection, the pure mechanical continuously variable transmission can be achieved; through the series connection between the two planetary groups, the output torque and speed can be automatically regulated at any time according to changes in the external resistance torque,and then the perfect mechanical intelligent continuously variable transmission can be achieved; a gear drive mode is adopted by the mechanical continuously variable transmission method, and the mechanical continuously variable transmission method has the advantages that the noise is low, the durability is high, the cost is low, and the efficiency is high; and furthermore, a one-way clutch is connected between the two planetary groups, so that the internal rotation can be prevented.

Description

technical field [0001] The invention relates to the field of continuously variable transmission, in particular to a mechanical continuously variable transmission method composed of a double planetary mechanism and a continuously variable transmission mechanism. Background technique [0002] At present, transmissions are commonly used in lathes, automobiles, and other mechanical devices and equipment that require variable speeds. For example, in a car, the transmission is one of the necessary components for the operation of the car. The car changes the torque on the crankshaft of the engine through the transmission, thereby changing the speed of the car and adapting to different driving conditions. [0003] At present, a large number of transmissions are used in various industries, especially in the automotive industry, there are various transmission solutions, such as MT, AMT, AT, CVT, DCT, etc., each of which has its advantages and disadvantages. [0004] all kind...
