Abstract

The invention discloses an electronic control hydraulic automatic gear shifting which comprises a power unit, a hydraulic integrating block, a gear-shifting control module and a clutch control module, wherein the power unit is connected with a one-way valve and a high-pressure filter through a high-pressure oil pipe for pressurizing an energy storage on the hydraulic integrating block, wherein the energy storage is connected with two gear-shifting electromagnetic valves for controlling the gear-shifting control module, two gear-shifting electromagnetic valves for controlling a gear-shifting oil cylinder and a clutch switching electromagnetic valve set through an oil pressure total electromagnetic valve; and the clutch switching electromagnetic valve set is connected with a runner plate for controlling rapid and slow integration of a clutch. The electronic control hydraulic automatic gear shifting effectively solves the problem of difficult matching of the same type of different manual and mechanical gear shifting, simplifies the complexity of control software, and improves the accuracy and the reliability of the clutch control.

Description

technical field [0001] The invention relates to an automobile transmission, in particular to an electronically controlled hydraulic automatic transmission system. Background technique [0002] The AMT system, without changing the integration of the main structure of the original manual mechanical gearbox, replaces the separation and engagement of the clutch and the gear selection and shifting actions of the transmission that were previously completed manually by installing an automatic device controlled by a microcomputer. Realize the automation of the whole process of gear shifting. [0003] There are mainly three types of AMT control methods currently developed: [0004] (1) Electronically controlled electric: refers to the automatic control of the clutch and shifting by adding an electric system controlled by a motor to the clutch and shifting part of the manual mechanical transmission. The advantage is that the driving system is simple, the manufacturing cost is low an...
