Description
Technical field
The present invention relates to a kind of autosynchronous shifting arrangement for automobile.
Background technique
Automobile automatic gear is an important component part of automobile electrically-controlled technology.Automatic gearbox has 3 types at present: automatically controlled hydraulic machine automatic transmission (being called for short AT), electric control mechanical type automatic speed variator (being called for short AMT) and continuous variable velocity ratio automatic transmission (being called for short CVT).Electric control mechanical type automatic speed variator is the system that adopts microcomputer control and hydraulic control unit to form on the hand gear system-based that dry clutch and fixed axis gear formula are made up of the level mechanical transmission.Compare with AT, have: the transmission efficiency height, fuel economy is good, simple in structure, cost compare AT cheap, be fit to characteristics such as various vehicles, but shift smoothness is not as AT, more be owing to clutch, accelerator pedal in the gearshift procedure must just can make shift time the shortest with selecting the gear-change operation cooperation, and gear shift is steady, so the control difficulty is bigger than AT.Select different three kinds of hydraulic drive type, air pressure drive-type and the motor-drivens that are divided into of the maneuverability pattern of gear shift and clutch according to the electric-controlled mechanical automatic speed-changing system.Wherein, the motor-driven electric-controlled mechanical automatic speed transmission is to adopt direct current motor to drive to select gear shift machinery and clutch, belongs to electric driving mode, therefore, it simple in structure, cost can be cheaper.Motor-driven electric-controlled mechanical automatic transimission (AMT system) mainly is made up of three parts: controlled system, electronic controller (ECU) and various kinds of sensors.Controlled system comprises speed changer, clutch and motor.During gear shift, the adjusting of the gear-selecting-shifting mechanism of speed changer, the separation of clutch and joint, engine air throttle all needs to control automatically.Sensor comprises velocity transducer, shifter, gear position sensor, acceleration transducer etc.Electronic controller comprises each signal processing unit, microprocessor, program and data storage, drive circuit, display unit, self-diagnosis of trouble unit and working power etc.Said AMT system or non-automatic transmission vehicle, control procedure comprises Starting Control, gear shift control and clutch for clutch control.When no matter automobile is in the starting stage or needs the conversion speed of a motor vehicle in the process of moving, all need to carry out separation, joint and the gear-change operation of clutch.As everyone knows, clutch separation belongs to motor has torsion output to separate, because of separation has the stroke cycle, so its process reaches tens to the hundreds of millisecond.And bonding state master passive tooth all has very high speed difference, causes inevitable system shock.This whole gearshift procedure that reaches the hundreds of millisecond of prior art has had a strong impact on power performance and lifetime of system, and its clutch causes whole drive system and clutch to damage in early days because of the frequent impact combination.
Summary of the invention
The objective of the invention is, a kind of automatic transimission that need not to carry out clutch separation, splice program in the vehicle driving process during automatic speed changing gear shift is provided, can shorten the power interruption time in the gearshift procedure widely, improve the power performance of vehicle, reduce the impact of clutch to greatest extent, need not to change the target of clutch to realize the integeral vehicle life cycle preferably.
The technology technical conceive of the present invention of realizing above-mentioned purpose is: the same with existing motor-driven electric-controlled mechanical automatic transimission (AMT system), consist predominantly of the controlled system and electronic controller (ECU) and the various kinds of sensors that comprise speed changer, motor and clutch.Characteristics of the present invention are, be fixed with one and be in the electromagnetic brake of normally open with the flywheel outer rim on flywheel casing, and this electromagnetic brake is made up of solenoid, moving iron core, brake casing, brake shoe and return spring.Moving iron core is set in the volute that is located in the brake casing, and brake shoe is connected an end of moving iron core, and at the moving core ends overhead at this brake shoe rear position spring once.Said the present invention, when needs are shifted, only need the operation gas pedal, when the speed of a motor vehicle and engine speed reach setting value, microprocessor is promptly controlled electromagnetic brake engine flywheel is implemented braking, and the control speed changer implements to select the gear shift operation, when the gearbox microprocessor chooses institute gear shift position, calculate institute's gear shift speed ratio simultaneously, and according to the required synchronous speed of this speed ratio motor.By control throttle and electromagnetic brake, realize required rotating speed again, finish synchronous nothing and impact flexible gear shift.
Be further to improve not have and separate shifted speed, the present invention also can be provided with one with the throttle actuator of gas pedal associated.This throttle actuator is made up of pedal connecting rod, acceleration solenoid, deceleration solenoid, actuator housings, two-way moving iron core, throttle connecting rod and two return springs.Quicken solenoid and deceleration solenoid and be arranged on the actuator housings both sides, the centre is cut off by body wall, two-way moving iron core is set in the acceleration, deceleration solenoid simultaneously, and an end of this two-way moving iron core is connected with the throttle connecting rod, and the end of this end overhead once the position spring.The housing of the other end of two-way moving iron core is provided with the pedal connecting rod, can be connected with gas pedal, and be provided with another return spring between pedal connecting rod and this two-way moving iron core.Said throttle actuator like this, main effect is the reaction velocity that improves the rotating speed of motor, to reach quick tracking microprocessor given speed.
As mentioned above, the present invention need not cut-off clutch when making vehicle work together speed change in the process of moving, be that vehicle can be implemented automaitc shfit and does to move under not separation of clutch state, therefore can improve shifted speed greatly, thereby raising vehicles dynamic performance, and can reduce the impact of clutch to greatest extent, and improve the life-span of clutch, may realize promptly that also integeral vehicle life need not to change the target of clutch in the cycle.
