Description
Technical field
The invention belongs to transmission-like, specifically a kind of three axle 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 wheel all the time, realizes power gear shifting, guarantees that vehicle has good acceleration performance.Double-clutch speed changer develops based on the parallel-axis type manual transmission, and it has inherited many advantages such as the manual transmission transmission efficiency is high, installing space is compact, quality is light, price is 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.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 reduces 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 relatively large arrangement space into speed changer.
Combined clutch single shaft export structure is compact, and footprint is little, is applicable to the limited speed changer of arrangement space.But accuracy of manufacturing and life requirements to combined clutch and driving-shaft assembly component are high, also need solve simultaneously the technical problems such as the cooperation of combined assembly and heat radiation.The basic utilization ratio of original MT component is restricted, so development cost is relatively high.
The speed changer axial length has been shortened in the output of combined clutch twin shaft, effectively improve system stiffness, be applicable to the less complete machine structure of axial dimension requirement, 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 relatively large arrangement space into speed changer.
Double clutch system has 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, the torque overload protection, efficient is high, cost is lower, do not need the advantage such as auxiliary power.Dry clutch absorbs larger heat by pressing plate and flywheel, and the speed that sliding wear is produced heat is insensitive, but the air heat radiation is slower, and 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 preferably controllability and controls quality, and structure is more single, have pressure distribution evenly, wearing and tearing are little and even, the transmitting torque capacity large, need not adjust specially the characteristics such as friction plate gap.Because it is cooling with the hydraulic oil pressure, skid for a long time with the high gear starting when allowing starting and can scaling loss not serve as a contrast face, be widely used on the clutch of Modern Automotive Automatic Transmissions.But be between the driving and driven friction plate of the multidisc clutch in separated state because mutually trackslipping through lubricant oil, produce larger surface friction drag, make the corresponding reduction of transmission efficiency of speed changer.
Summary of the invention
Purpose of the present invention provides a kind of dual input shaft, compact structure, coordinates with the joint gear ring that casing is connected the three axle dual-clutch transmissions of realizing Parking without the synchronizer on the idle pulley that reverses gear, employing output shaft for the deficiencies in the prior art.
The present invention realizes by following technical proposal:
A kind of three axle dual-clutch transmissions, comprise two clutches, two input shafts, an output shaft, two clutches are connected with corresponding input shaft respectively, arrange odd number gear driving tooth wheels on an input shaft, arrange even number gear driving tooth wheels on another root input shaft; Arrange the driven tooth wheels on output shaft, the driving gear of two input shafts shares corresponding driven gear, and the driving gear that reverses gear is arranged on wherein on an input shaft, and the driven gear that reverses gear is arranged on another root input shaft, and driving gear meshes with reversing gear.
