Description
Technical field
The utility model relates to shifting vehicle gearbox technical field, is specifically related to a kind of ATM based on forced maneuver formula speed changer automobile and emulates operating mechanism.
Background technique
Automatic transmission except AMT, also have AT[hydraulic automatic speed variator], CVT[stepless speed variator] and DCT[double-clutch automatic gearbox] etc. various ways, from technical standpoint consideration, AT complicated structure, cost is higher; CVT, by the restriction of transmitting torque, is also difficult to application on heavy trucks the driver according to current technology; DCT is a kind of up-to-date technology, does not still have heavy truck to adopt the precedent of DCT in the world; And AMT refers to automatic mechanical transmission, also claiming auto-manual variable transmissions, is a kind of speed change gear combining hand gear and automatic speed changing function.Domestic original manual transmission manufacturing mechanism and technology can retain and continue to use.So in general, China Heavy-duty Truck Market automatic transmission technology path adopts AMT the most reasonably to select.
ATM[Automatic Mechanical Transmission] be the abbreviation of Automated Mechanical Trans mission, also auto-manual transmission is become, this combine with technique advantage of automatic transmission and manual transmission, decreases the power loss of speed variator system to greatest extent.First this manual/auto speed variator system is released in its 911 vehicle by professional high performance sports car manufacturer of Germany Porsche, is referred to as Tiptronic.As the work shouldering ancient cooking vessel of Porsche, from appearance since 7 years, with its high stability and leading science and technology, worldwide extensively praise by each side.
And domestic heavy truck overload is serious, do car load timing signal, just can not according to appraising and deciding gross mass to do, and to exceed a lot, even more than one times, therefore ATM mates work with car load is technological difficulties, the enterprise road of domestic many heavy trucks research and development AMT is tried for many years, form industrialization not yet, also rarely have application on heavy trucks the driver, this is one of important reason.And the manual gear speed changer of China has completely solved this problem.
The application installs the further upgrading and improvement that a set of automatical control system does additional based on a kind of control mechanism of numerically-controlltransmission transmission of the applicant's publication number 103453132A, the main difficult technical faced is the problem of " clutch synchronization ": no matter be use stepper motor or the applicant's disclosed gearshift multiposition cylinder and block selecting multiposition cylinder to promote clutch shifter at present, make clutch separation or joint, all no problem during clutch separation, if but do not consider the matching relationship between the rotating speed of motor and clutch rotational speed, all can occur when clutch engages in conjunction with time alter car, rub the impact phenomenons such as car with the hands, noise is also very high.This is because in whole shift process, no matter add gear or subtract gear, having the rotating speed at two places to need in transmission system synchronous: a place is that the rotating speed of the inner gear to be engaged of speed changer needs synchronous, and it is completed by synchronizer, need not we worry about; Another place's motor also needs synchronous with the rotating speed between clutch plate, i.e. " clutch synchronization ", driver oneself must be depended on control in manual gear manipulator, need to solve in the utility model and how grasped various driving skills incorporate having the old driver enriching driving experience wherein.
Summary of the invention
The purpose of this utility model there is the problems referred to above and the market demand for prior art, jump out of the hedge of complete machine research and development, develop a kind of based on very ripe manual transmission, plug-in independently manipulation module, thus avoid the technical barrier that ATM mates with car load, thus realize a kind ofly having complete ATM effect, but the AMT being different from AMT speed changer complete machine emulates operating mechanism.
For realizing this object, disclosed in the utility model, technological scheme is:
A kind of ATM based on forced maneuver formula speed changer automobile emulates operating mechanism, comprise command signal unit, information process unit, Electromagnetic Control unit, performance element, unlike the prior art: described command signal unit comprises gear Joystick 1, gear on-off 2, each gear on-off 2 is connected with information process unit, and the control of engine speed unit that information process unit and Electromagnetic Control unit, motor carry is connected, and Electromagnetic Control unit is connected with performance element; Described performance element comprises gearshift multiposition cylinder 30 and block selecting multiposition cylinder 40, gearshift multiposition cylinder 30 and the end wall of each cavity both sides of block selecting multiposition cylinder 40 all arrange contact-type location switch 3, and described location switch 3 is connected with information process unit respectively.Adopt this technological scheme, former manual gear driving model can be converted to auto-manual driving model.
Further, also comprise the intelligent speed-regulating cylinder be connected with Electromagnetic Control unit, described intelligent speed-regulating cylinder comprises a double-acting cylinder 50, the affixed gas pedal of piston rod of double-acting cylinder 50, the affixed engine throttle pull bar of cylinder body, two gas ports of double-acting cylinder 50 is arranged respectively the first one-way throttle valve 5 and the second one-way throttle valve 6 that a cut-off direction is contrary.Adopt this technological scheme, can ensure that selected gear one fixes on optimum oil consumption region, the gearshift opportunity in the best is necessarily selected in gearshift opportunity.And the randomness that manual gear operates due to people, and the difference of artificial judgment, be then difficult to ensure above-mentioned 2 points always.So this emulation AMT can accomplish more fuel-efficient than manual transmission, have simultaneously natural and smooth as driving experience.
Further, also be included in the unidirectional controlled sequence valve 7 arranged between Electromagnetic Control unit and former automobile clutch sub-pump cylinder, described unidirectional controlled sequence valve 7 comprises one-way throttle valve 73, with the one-way valve 72 of one-way throttle valve 73 parallel connection, in parallel with one-way throttle valve 73 and contrary with one-way valve 72 conducting direction unidirectional adjustable pressure valve 71.Adopt this technological scheme, thorough when making clutch separation, steady and smooth during joint.
Further, described Joystick 1 also arranges fast lifting position switch 4, and fast lifting position switch 4 is connected with information process unit.Adopt this technological scheme can realize increase and decrease gear fast.
Further, described information process unit is the one in single-chip microcomputer, single board computer, PLC, PC, ECU.
Compared with prior art, the utility model universality is strong, can realize modularization, integrated production, and without the need to considering the design of transmission control when car replacement is regenerated, Installation and Debugging are simple and convenient.Avoid the technical barrier that ATM mates with car load, thus realize a kind of there is complete ATM effect, but the AMT being different from AMT speed changer complete machine emulates operating mechanism.
