Problems solved by technology

In addition, there is a large speed difference between the active and passive gears in the combined state, resulting in inevitable system impact
The entire gear shift process of the prior art, which lasts several hundred milliseconds, seriously affects the power performance and system life. The clutch is combined due to frequent impacts, resulting in early damage to the entire transmission system and the clutch.

Abstract

The invention relates to a vehicle automatic synchronous shift device, which is characterized in that: it comprises a speed variable device, an engine, and a clutch as the controlled system, and an electric controller and variable sensors. The frame of engine flywheel is fixed with an open electromagnetic brake; therefore, the automatic shift device controlled by microprocessor can shift without separating the clutch. The invention can improve the shift speed to reduce the impact of clutch most. Therefore, the clutch can avoid be replaced in the whole life of vehicle.

Description

technical field [0001] The invention relates to an automatic synchronous shifting device for automobiles. Background technique [0002] Vehicle automatic transmission is an important part of automobile electronic control technology. There are currently three types of automotive automatic transmissions: electronically controlled hydraulic mechanical automatic transmission (abbreviated as AT), electromechanical automatic transmission (abbreviated as AMT), and continuously variable ratio automatic transmission (abbreviated as CVT). Electromechanical automatic transmission is a system composed of microcomputer control and hydraulic control device on the basis of manual transmission system composed of dry clutch and fixed shaft gear type stepped mechanical transmission. Compared with AT, it has the characteristics of high transmission efficiency, good fuel economy, simple structure, relatively lower cost than AT, and is suitable for various models, but the smoothness of shifting...
