Abstract
The utility model relates to the controller of an automatic gear shifting system for cars, comprising an electronically controlled dry friction clutch and a synchronous gearbox. The utility model has the advantages of high fuel economy, simple structure and simple operation like the common automatic gearbox. The utility model adopts an electronic control unit ECV to pass through a sensor, a clutch actuator, a shift actuator and a hydraulic system and organized according to the practical performance of experienced drivers driving stick shift cars; a shift program realizes the automatic gear shifting.
Description
The utility model is a kind of control system that adopts the automatic speed-changing system of electronically controlled dry friction clutch or turbine transformer and synchronized gear transmission composition.
At present, the automatic transmission with hydraulic torque converter that turbine transformer that automobile adopted and planetary transmission are formed, it utilizes the liquid transfer moment of torsion by pump impeller, turbine and guide wheel, therefore needs cooling system.Several groups of friction clutches in the hydraulic efficiency servo control planetary transmission and brake collar make planetary transmission form different speed ratio gears, reach the self-shifting purpose.Must right this system can increase moment of torsion, but efficient is very low during low-speed running, complex structure, manufacture difficulty is big, debug difficulties, the domestic batch manufacturing of incompatibility.
The purpose of this utility model provides a kind of automatic transmission with hydraulic torque converter of Vehicle Electronic Control, and it can not only be according to the automatic conversion gear of the operation conditions of road conditions and driving engine, and automatic guidance clutch operating simultaneously.
The utility model is a kind of device of electromechanical integration, and it is by electronic control unit, riding manipulation select lever and acceleration pedal, and the sensor of mode of operations such as reflection driving engine, the electromagnetic valve hydraulic actuator of power-transfer clutch and change-speed box is formed.The gearshift program of system according to the most experienced driver driving hand-operated transmission automobile practical operation work out.Thereby tangible oil-saving effect arranged.Change-speed box is converted by common full hand-operated transmission synchronously, but block selecting and gearshift finished by the electromagnetic valve hydraulic actuator, also can be manual.The electromagnetic valve hydraulic actuator is made of the body of actuator block selecting oil cylinder and shift gears oil cylinder and clutch oil cylinder.On body, directly assemble electromagnetic valve, to form the integral body of a compactness.Block selecting oil cylinder and gearshift oil cylinder all are beidirectionals.On valve piston suit the transportable big piston of relative valve piston, oil cylinder is divided equally and is size two partly, block selecting and gearshift oil cylinder have three definite positions.Thereby avoided adopting complicated servomechanism and registration device, reached the pinpoint purpose of every retaining.Clutch oil cylinder adopts the unidirectional action structure.Spring is adopted in the answer of piston, and the control that helps clutch engagement like this makes designs simplification by pulse width modulation.The fuel feeding of this actuator partly is made up of oil pump and accumulator, and gear type pump is by the driving engine direct drive.
Because adopt such scheme, this automatic transmission with hydraulic torque converter can be accomplished simple in structure, debugging is easy to handle and have higher fuel efficiency easily.
Description of drawings: Fig. 1 is the cutaway view of electromagnetic valve hydraulic actuator.
Fig. 2 is the cutaway view along Figure 1A-A arrow direction.
Fig. 3 is the clutch control transmission diagram.
Fig. 4 is the fluid control schematic diagram.
As shown in Figure 3, diaphragm spring dry friction clutch (9) promotes lever system by clutch control oil cylinder (8), and lever system (11) promotes release thrust bearing (10) and controls.As shown in Figure 2, the manipulation oil cylinder of power-transfer clutch and change-speed box is fitted together, clutch stroke sensor (7) is contained on the clutch control oil cylinder (8), and block selecting oil cylinder (6) and gearshift oil cylinder (1) all have three positions, and they constitute the body of electromagnetic valve hydraulic actuator.
Power-transfer clutch actuator as shown in Figure 2 is by three two-position two-way solenoid valve controls shown in Figure 4, two-position two-way solenoid valve among Fig. 4 (15) control oil-feed, two-position two-way solenoid valve (16) and (19) control unloading, when electromagnetic valve (15) is opened, electromagnetic valve (16) and (14) are when closing, high pressure oil flows to oil cylinder (8), and power-transfer clutch among Fig. 3 (9) separates.Close when electromagnetic valve (15), electromagnetic valve (16) and (19) are also closed, and then power-transfer clutch (9) still keeps separating.Have only when electromagnetic valve (16) and (19) and also open and electromagnetic valve (15) when closing, fluid flows back to fuel tank (12) under the spring force effect, and power-transfer clutch (9) engages.Valve (19) channel diameter in two electromagnetic unloading valves is big, and electromagnetic valve (16) channel diameter is little, can make power-transfer clutch (9) smooth engagement.Power-transfer clutch (9) engaging speed is controlled by pulse width modulation.Clutch stroke sensor (7) determines that by electronic control unit pulse width modulation is to obtain desired power-transfer clutch speed again partly engaging signal passes to electronic control unit.
Fig. 1, change-speed box actuator shown in Figure 2 partly are made up of block selecting oil cylinder (6) and gearshift oil cylinder (1) two.The axis of oil cylinder (1), (6) should be corresponding vertical.The handing-over fulcrum of gear level (2) is on the piston rod (5) of block selecting oil cylinder (6).With Fig. 1, shown in Figure 2, be pulled to the shift fork position of corresponding power shift gear when gear level (2) after, gear level moves the shift fork in the change-speed box, finishes gearshift.Block selecting oil cylinder (6) and gearshift oil cylinder (1) all are beidirectionals.With connecting rod (5) or (25) be above the single-piece valve piston suit a transportable big piston of relative valve piston (22) or (24).As shown in Figure 4, a two-position three way magnetic valve all is equipped with in every chamber.Electromagnetic valve (18) and (21) are the electromagnetic valves of block selecting oil cylinder (6).Electromagnetic valve (17) and (18) are the electromagnetic valves of gearshift oil cylinder (1).When two electromagnetic valves of an actuator hlydro-cylinder all during cut-in pressure oil, the piston both sides stop at midway location under the equipressure effect, and the gearshift actuator is in neutral gear position.If electromagnetic valve makes a chamber oil-feed, and during the oil return of another chamber, piston moves to an end, thereby has realized block selecting and gearshift.At Fig. 1, on block selecting shown in Figure 2 and the gearshift actuator piston rod travel switch (3) and (4) are housed all, make electronic control unit measure the control position of actuator and the performance of block selecting gearshift action.
Electronic control unit obtains feedback signal from each actuator, and obtains driver's the driving intention and the motoring condition of automobile from each sensor.
Among Fig. 4, oil pump (13) is directly driven by driving engine.Two-position two-way solenoid valve (14) is a main valve.Gear signal (26) expression drive range.
