2-axis 8-speed transmission mechanism of an automatic transmission for a vehicle

摘要

More specifically, the present invention relates to an automatic transmission for a vehicle, and more particularly, to a planetary gear set, a wet type multi-plate clutch and a multi-plate brake, which are capable of obtaining various speed ratios of two forward speeds and eight forward speeds, Speed automatic transmission in which a reduction in impact upon a shift is improved and a ride quality is improved, a conventional four-speed automatic transmission has a reliability and durability corresponding to the power performance of a high output engine due to a limited reduction ratio. And it was impossible to drive with low fuel consumption and low noise. SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and it is an object of the present invention to provide a speed change device capable of improving the fuel economy, acceleration performance, Thereby providing a transmission device.
