Description
Technical field
The utility model belongs to automobile machinery automatic transmission case technical field, particularly a kind of novel automatic transmission case final controlling element.
Background technique
Along with the fast development of automobile pollution and the rapid increase of amateur driver's quantity, automatic gearbox is just presenting fast development trend.Present automatic gearbox mainly contains hydraulic mechanical type automatic transmission (AT), stepless speed variator (CVT), and three kinds of electric control mechanical type automatic speed variators (AMT).
Realizing on automobile that the self-shifting speed changer is the hydraulic mechanical type automatic transmission, be called for short AT, also is present most widely used automatic gearbox.It does not cut off power shfit, has starting, gear shift is smooth-going, but resisting moment is changed advantage such as self adaption.But shortcomings such as it also has complex structure simultaneously, and difficulty is made, and transmission efficiency is low.
Manually fixedly the shaft type gear-shift transmission is the step change driving mechanism, and its advantage is the efficient height, and cost is low, and mature production technology is widely used in China at present.Shortcoming is the gear shift difficulty, and power interruption during gear shift requires pilot control skilled, so people expect that it can realize automation.Computer Control Technology makes this gear realize that automaitc shfit becomes possibility.Electric control mechanical type automatic speed variator (AMT) is exactly the product that makes the fixed shaft transmission automation by microcomputer control.It kept original gear speed changer transmission efficiency height, installing space compactness, in light weight, cost is low, easy manufacturing, safeguard advantages such as easy; And realized the automation of starting, gearshift procedure, in handiness, possessed the advantage of AT.AMT with its economy, easy to usely, simple and safe have better travelling comfort again and favored; and it also has the advantage that the existing manual transmission of the desired high fuel economy of present automobile industry development, low emission and protection is produced investment; therefore be subjected to the attention of each big automobile factory, become the new automobile automatic transmission of suitable China's national situation.
AMT is on the basis of conventional fixed axis transmission and dry clutch, application electric technology and automatic speed changing theory, with electronic control unit (ECU) is core, separation by the actuating mechanism controls clutch with engage, select gear-change operation and the fuel feeding by electronic equipment control motor, realize starting to walk, the automatic manipulation of gear shift.The basic thought of AMT control is: according to driver's the intention (accelerator pedal, brake petal, Joystick etc.) and the state (engine speed, input shaft rotating speed, the speed of a motor vehicle, gear) of vehicle, according to suitable control law (process of power shift, clutch rule etc.), the Power Train (motor, clutch, speed changer) of vehicle is carried out united control by means of corresponding actuator's (clutch actuating mechanism, gear-selecting and shifting executing mechanism) and electronic equipment (engine oil control electronic equipment).
ECU (Electrical Control Unit) (TCU) is shouldered collection, processing and the control decision of multichannel input signal and sending of execution command in real time, online according to software program; Then according to the instruction of TCU, control electromagnetic valve makes actuator automatically finish clutch separation, joint and actions such as speed changer choosing, gear shift to operating control mechanism, and gearshift procedure is finished automatically.
But, in this control system,, need further investigation control device and control strategy on the one hand if want to make the performance of system to reach desirable condition, improve the control effect; On the other hand, then need to excavate by the dynamic performance of control elements as far as possible, make the cooperation of whole system perform to perfect degree.This is because if the uncontrollable words of controlled device, control system cisco unity malfunction then, and the height of controlled device performance have also influenced the performance of whole system significantly.
In the AMT system, for there are two solution routes the time that shortens power interruption: the one, the speed of response of raising controlled device, the 2nd, the structure of change controlled device.The present invention sets about from above-mentioned two aspects exactly, shortens the power interruption time of system by structure optimization.
Summary of the invention
At above-mentioned situation, the utility model purpose be for a kind of work of electric control mechanical type automatic speed variator (AMT) design accurately and reliably, the fast a kind of novel automatic transmission case final controlling element of speed of response.
The technical solution of the utility model is achieved in that
A kind of novel automatic transmission case final controlling element, it is characterized by: it is by hydraulic oil source, shifting final controlling element and clutch actuator are formed, motor in the hydraulic oil source links to each other with oil hydraulic pump, one-way valve a is installed on the oil hydraulic pump, one-way valve b, proportional electromagnetic valve d and selector valve also are installed, wherein one-way valve a is connected with accumulator, strainer and secondary filter are installed between oil hydraulic pump and fuel tank, hydraulic oil source links to each other with clutch actuator by one-way valve a, link to each other with the shifting final controlling element with proportional electromagnetic valve d by selector valve, clutch actuator and shifting final controlling element also are connected with fuel tank in the hydraulic oil source, the shifting final controlling element is made up of one group of oil cylinder arranged side by side, oil cylinder has two filler openings, two filler openings are connected respectively at a two-bit triplet gear shift solenoid valve, clutch actuator is made up of an oil cylinder, and flow-off is arranged on the oil cylinder, and proportional electromagnetic valve c and clutch position sensor also are installed.
Thereby advantage of the present invention can be by embodying to the raising of vehicle performance with to reduction by two aspects that the complexity of simplifying gear-selecting and shifting executing mechanism reduces the automatic transmission cost of production.
At first, because utilize the electric control mechanical automatic gearbox gear shifting mechanism of the designed exploitation of the present invention, cancelled the gear selecting action, speed is very fast, and shift time is short, so vehicle has good power character.
Secondly, cut down finished cost by the complexity of simplifying actuator.Can reach a conclusion from the working principle of gearbox, gearshift power and the gearshift time of gearbox on each gear is different.For same gearbox, its upshift power is less than downshift power, and the gearshift power of low gear is greater than the gearshift power of high gear.If therefore the principal pressure of system is unadjustable in shift process, for optimizing the output gearshift power of final controlling element, must change the size of each oil cylinder of final controlling element, if the size difference of each oil cylinder, at first can increase the difficulty of processing of final controlling element, secondly each oil cylinder associated components does not have interchangeability, will inevitably cause the increase of the cost of final controlling element like this when producing in enormous quantities.If the inlet pressure of shifting final controlling element is adjustable, just can realize the same size of a plurality of oil cylinders, realize different ouput forces by the pressure of adjust system.Therefore used four or more three position oil cylinders arranged side by side in the present invention, the structure of three position oil cylinders is identical, and conformity of production is good, and is simple in structure, so cost of production is low.
