Description
Technical field
The utility model belongs to transmission-like, specifically is a kind of three dual-clutch transmissions.
Background technique
Dual-clutch transmission switches by the coupling of two clutches realizes the gearshift action, and gearshift rapidly steadily.In shift process, the power of motor constantly is passed on the wheel all the time, realizes power gear shifting, guarantees that vehicle has good acceleration performance.Double-clutch speed changer is based on parallel-axis type manual transmission development and comes, and it has inherited many advantages such as manual transmission transmission efficiency height, installing space compactness, light weight, price are low.
The dual-clutch transmission structure mainly contains three kinds at present: the output of double clutch single shaft, the output of combined clutch single shaft and the output of combined clutch twin shaft.Three kinds of structures cut both ways:
The output of double clutch single shaft has utilized existing equipment and technology to greatest extent, and is suitable with manual transmission component machining difficulty, effectively reduced development cost.Compare this structure with manual transmission and can make transmission shaft to shorten length, system stiffness improves, and still, the height of speed changer increases, and requires to reserve big relatively arrangement space into speed changer.
Combined clutch single shaft export structure compactness, footprint is little, is applicable to the speed changer that arrangement space is limited.But, also need solve technical problems such as the cooperation of combined assembly and heat radiation simultaneously to the accuracy of manufacturing and the life requirements height of combined clutch and driving-shaft assembly component.The basic utilization ratio of original MT component is restricted, so development cost is higher relatively.
Combined clutch twin shaft output shortening speed changer axial length, improve system stiffness effectively, be applicable to the complete machine structure that the axial dimension requirement is less, identical with double clutch single shaft export structure, also exist technological difficulties and the high development cost same with the coaxial output of double clutch.The same with double clutch single shaft export structure, require to reserve big relatively arrangement space into speed changer.
The double clutch system of existing dual-clutch transmission mainly contains dry clutch and two kinds of forms of wet clutch.Dry type diaphragm spring single plate clutch have the secondary part rotary inertia little, simple in structure, easy to adjust, separate thoroughly, torque overload protection, efficient height, cost are lower, do not need advantage such as auxiliary power; dry clutch absorbs big heat by pressing plate and flywheel; the speed that sliding wear is produced heat is insensitive; but the air heat radiation is slower; heat is difficult for distributing at short notice, so it is subjected to the total heat quantitative limitation of sliding wear generation.
Wet clutch has controllability and controlling performance preferably, and structure is more single, have pressure distribution evenly, wearing and tearing are little and even, the transmitting torque capacity big, need not adjust characteristics such as friction plate gap specially.Because it forces cooling with hydraulic oil, skid for a long time when allowing starting and high gear starting and can scaling loss lining face, be widely used on the clutch of Hyundai Motor automatic transmission.But be between the driving and driven friction plate of the multidisc clutch in the separated state because of trackslipping mutually, produce bigger surface friction drag, make the corresponding reduction of transmission efficiency of speed changer through lubricant oil.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, and three dual-clutch transmissions of the no idle pulley of a kind of dual input shaft, compact structure, reliable performance, good economy performance are provided.
The utility model is realized by following technical proposal:
A kind of three dual-clutch transmissions, it is characterized in that: comprise two clutches, two input shafts and an output shaft, power by motor with gear transmission or the band transmission mode drive two clutches, two clutches link to each other with two input shafts respectively, wherein arrange odd number retaining driving tooth wheels on an input shaft, arrange even number retaining driving tooth wheels on another root input shaft, connect by synchronizer between driving gear; Arrange the driven tooth wheels on the output shaft, two shared corresponding driven gears of input shaft driving gear, the driving gear that reverses gear is arranged on the input shaft, the driven gear that reverses gear is arranged on another root input shaft, output power by corresponding retaining driving gear and the driven gear engagement that is connected with it, realize reversing gear.
Arrange two synchronizers on each input shaft of the utility model, be connected with each retaining driving gear respectively.
The driven gear corresponding on the shared output shaft of the driving gear of correspondence difference on two input shafts of the utility model with it, reduce the driven gear number on the output shaft, shortened the axial length of speed changer effectively, the ingenious characteristics of having utilized three of the utility model, saved idler shaft, make the designs simplification of gearbox, make speed changer compacter.
The utility model adopts dual input shaft to press certain distance and arranges, and does not use expensive concentric shafts, has utilized existing equipment and technology to greatest extent, has effectively reduced cost of production; And the axial length of speed changer is shortened, and system stiffness improves, and reliability increases.
