The double piece flexible disk mechanism of the double-clutch automatic gearbox is characterized in that each two nuts are arranged at one of three corners of flexible disk bodies, that is, six nuts are arranged, the flexible disk bodies are overlaid by double layers, centers of the flexible disk bodies are fixedly connected through splined hubs, the two flexible disk bodies, the six nuts and the splined hubs form a double piece flexible disk assembly, the double piece flexible disk assembly is sleeved on double clutches through the splined hubs at the centers, the splined hubs are in interference fit with the double clutches, the double piece flexible disk assembly is located between the double clutches and an engine flywheel, and the engine flywheel is fixedly connected with the six nuts on the double piece flexible disk assembly through six bolts. The double piece flexible disk mechanism of the double-clutch automatic gearbox has the advantages that good dynamic property and vibration performance of a transmission system can be achieved, and impulsive loads and axial vibration transmitted to the clutches from an engine can be reduced.
Description
Technical field
The utility model relates to a kind of double-clutch automatic transmission biplate flexible disk mechanism, belongs to the Technology of Automatic Transmission for vehicle field of auto manufacturing.
Background technique
Along with the fast development of automobile pollution and the sharply increase of amateur driver's quantity, automatic gearbox is just presenting fast-developing trend.Present automatic gearbox mainly contains hydraulic mechanical type automatic transmission (AT), stepless speed variator (CVT) and double-clutch automatic transmission (DCT).
Realizing on automobile that the self-shifting speed changer is the hydraulic mechanical type automatic transmission, be called for short AT, is also current most widely used automatic gearbox.It does not cut off power shfit, has starting, gear shift is smooth-going, but resisting moment is changed to the advantage such as self adaption.But the shortcomings such as it also has complex structure simultaneously, and difficulty is manufactured, and transmission efficiency is low.
Manually fixedly the shaft type gear-shift transmission is the step change driving mechanism, and its advantage is that efficiency is high, 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.Double-clutch automatic transmission (DCT) is automatic mechanical transmission of new generation, many advantages such as it has inherited that the manual transmission transmission efficiency is high, installing space is compact, lightweight, low price, fundamentally solved the cut-out power shfit problem that electric control mechanical type automatic speed variator exists, greatly improved the gear shift travelling comfort, guaranteed that vehicle has good power character and shift characteristic.
In double-clutch automatic transmission, each gear driving gear of speed changer is connected with two clutch C1, C2 arranging on input shaft respectively by strange, even number gear, and clutch C1, C2 replace transferring power to realize gear switch.
During DCT work, vehicle is first with certain gear operation, electrical control unit of automatic transmission (TCU) is about to next gear of the work of entering according to the signal judgement of related sensor, because this gear clutch also separates not transferring power, therefore the instruction hydraulic pressure controlling solenoid valve is controlled gear-shifting actuating mechanism very easily, mesh in advance this gear, when vehicle operating reaches shift point, only need the clutch separation that will work, another clutch is engaged simultaneously, make automobile travel with next gear.In gearshift procedure, the power of motor constantly is passed to wheel all the time, so the gearshift procedure completed like this is power shfit.Vehicle has been realized timing, will improve greatly the gear shift travelling comfort, also guarantees that vehicle has good Economy, and the aspects such as vehicle oil consumption and discharge are made moderate progress simultaneously.
In the double-clutch automatic transmission structure, the flexible disk assembly is installed between engine flywheel and clutch, plays and reduces the axial and vibration radially that motor transmits, and the protection clutch is avoided the effect of impacting.At present, the general monolithic flexible disk structure that adopts of design, its shortcoming is intensity difference, and rigidity is large, and the effect of damping is bad, and this patent adopts the biplate structure greatly to mention elastic characteristic, is conducive to the work of clutch.
Summary of the invention
The purpose of this utility model is to provide a kind of double-clutch automatic transmission biplate flexible disk mechanism, and it has the power train of making and obtains good power character and vibration characteristics, reduces motor and is delivered to impulsive load and the axial vibration on clutch.
The technical solution of the utility model is achieved in that double-clutch automatic transmission biplate flexible disk mechanism, it is characterized in that: all there are two nuts at three angles of flexible disk disk body, nut amounts to six, and the flexible disk disk body is fixedly connected with by splined hub for double-deck stack center; Two flexible disk disk bodies, six nuts and splined hub form biplate flexible disk assembly, biplate flexible disk assembly is enclosed within on double clutch by the splined hub at center, splined hub and double clutch interference fit, biplate flexible disk assembly is between double clutch and engine flywheel, and engine flywheel is fixedly connected with six nuts on biplate flexible disk assembly by six bolts.
Good effect of the present utility model is that it has the power train of making and obtains good power character and vibration characteristics, reduces motor and is delivered to impulsive load and the axial vibration on clutch, and also Ju has the mono-﹑ good manufacturability of Jie structure Jian and the low characteristics of cost.
The accompanying drawing explanation
Fig. 1 is structural drawing of the present utility model.
Fig. 2 is flexible disk body structure figure of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described: as shown in Figure 1, 2, double-clutch automatic transmission biplate flexible disk mechanism, it is characterized in that: all there are two nuts 1 at three angles of flexible disk disk body 2, nut 1 amounts to six, and flexible disk disk body 2 is fixedly connected with by splined hub 3 for double-deck stack center; Adopt the Placements of welding after two flexible disk 2 are close to six nuts 1, and with splined hub 3 also by being welded to connect, biplate flexible disk assembly is enclosed within on double clutch 6 by the splined hub 3 at center; Two flexible disk disk bodies 2, six nuts 1 and splined hub 3 form biplate flexible disk assemblies, biplate flexible disk assembly is enclosed within on double clutch 6 by the splined hub 3 at center, splined hub 3 and double clutch 6 interference fit, biplate flexible disk assembly is between double clutch 6 and engine flywheel 4, engine flywheel 4 is fixedly connected with six nuts 1 on biplate flexible disk assembly by six bolts 5, has the effect that reduces motor impulsive load and vibration.
Biplate flexible disk assembly working procedure is that six bolts 5 by being connected with engine flywheel 4 pass to six nuts 1 and two flexible disk disk bodies 2 by the moment of torsion of motor, after internal spline by splined hub 3 moment of torsion is passed to double clutch 6, splined hub 3 adopts the spline interference fit with double clutch 6, and design guarantees that the flexible disk assembly is connected with double clutch 6 reliably like this; The function of biplate flexible disk assembly is to utilize the elastic characteristic of flexible disk disk body 2 to reduce the vibration that motor passes to double clutch 6, comprise the footpath torsional vibration made progress and the distortion axially above produced due to alignment error that produce in engine flywheel 4 rotary courses, reduce torsional impact and axial vibration to double clutch 6 generations.
