  • Abstract Epicyclic-type automatic transmissions are used in automobiles widely. There
    are many advantages of epicyclic-type automatic transmissions. It is composed more
    densely, smaller and provide higher gear ratio. We can get different output speed by
    actuating different clutches or brakes. There are a lot of patents for epicyclic-type
    automatic transmissions, but most of them tends to be three degrees of freedom
    automatic transmissions or using embedded clutches or brakes and other complex
    constructions. It is a better choice if we could use relatively simple manufacturing and
    control of two degrees of freedom and external clutches and brakes in the same multi
    speeds, speed ratio of the same premise. Therefore, this study aims to propose a set
    of design process for two degrees of freedom parallel-connected epicyclic gear
    automatic transmissions and computerize the process. First, we established the lever
    diagram for eight-speed automatic transmissions. By decomposing lever diagrams to
    all possible three-point lines, then composing four different lines to get all possible
    eight-speed automatic transmission constructions. Then, we use direct-member
    -number method to get member number of all constructions. Determining the
    possibility of configuring clutches and brakes, excluding the construction
    which can’t configure the clutch and brake, establish the database can be configured.
    Finally, we determine a speed ratio for the eight-speed automatic
    transmissions, excluding the constructions doesn’t match the appropriate gear ratios.
    Drawing the diagram which comply the restriction for eight-speed automatic
    transmissions.
    Keywords: automatic transmission, lever diagram, direct-member-number method,
