Document Type and Number:
Japanese Patent JP3479743
Kind Code:
B2
Abstract:
A clutchless automatic transmission comprises a hyper-overdrive for connecting first and second drive transmitting members, and a planetary transmission for varying the speed and direction of the output shaft with respect to the second drive transmitting member. The planetary transmission includes (1) multiple forward transmitting gearsets for changing the speed transmitted by the second drive transmitting member into a speed ratio of at least three, (2) a backward transmitting gearset for changing the direction of rotation, (3) plural hydraulically driven brake members for selectively braking a carrier of the forward transmitting gearset or a carrier of the backward transmitting gearset, and (4) a transmission lever for driving the brake members based upon an electric signal. The planetary transmission meshes continuously with the input power source without a clutch. The configuration is simple and compact. A speed change can be accomplished easily with an electric signal.
