Benefits of technology

The present invention provides an automatic manual transmission system for vehicles with a traditional hand-held transmission mechanism. This system allows for partial use of the transmission while still allowing for effective gear shifts without interrupting power supply or causing any issues like decreased gear shift feel due to increased friction between gears.

Problems solved by technology

This patent describes how an automated manual transmission (AMT) uses actuators to shift gears when it's driven by an engine. However, if there are sudden stops where power from the AMT goes through, the gears will stop moving due to reduced force caused by the interruptions. These temporary reductions cause the gears to become less responsive with each other, leading to decreased gear shift performance.

Abstract

An automated manual transmission for a vehicle may include an input shaft configured to receive rotating force from a power source, an output shaft disposed parallel to the input shaft so that power is output from the output shaft, and a plurality of shift gear trains each comprising external gears respectively provided on the input shaft and the output shaft in such a way that the external gears circumscribe each other, the external gears forming a pair that embodies one of a series of shift ratios. Among the external gears that form a shift gear train in the plurality of the shift gear trains that embodies at least two adjacent shift ratios, either of two external gears that forms each of the shift gear trains may be connected to the input shaft or the output shaft by a planetary gear device.
