Abstract
The utility model relates to a double-clutch type automatic gearbox middle plate assembly which is characterized in that a middle shaft assembly is fixed on a middle plate through an output shaft pressing plate, an odd gear input shaft assembly and an even gear input shaft assembly are of a shaft sleeve structure, namely, the odd gear input shaft assembly is installed in an inner hole of the even gear input shaft assembly, the odd gear input shaft assembly and the even gear input shaft assembly are fixed on the middle plate through an input shaft pressing plate, and the odd-gear input shaft assembly and the even-gear input shaft assembly transmit power to a middle shaft assembly through gears at all gears. The double-clutch type automatic gearbox middle plate assembly is low in occupied space, simple in structure, large in borne axial force and reliable in fixing.
Description
Technical field
The utility model relates to plate assembly in a kind of double-clutch automatic transmission, 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.
The plate assembly plays the effect of axial restraint transmission countershaft assembly and odd number shelves even number shelves input shaft assembly in double-clutch automatic transmission (DCT), and it need to meet and bears axial force great ﹑ and meet strength and stiffness requirement and accurate positioning.
Summary of the invention
The purpose of this utility model is to provide plate assembly in a kind of double-clutch automatic transmission, and its little ﹑ that takes up room is simple in structure, it is fixing reliable to bear axial force great ﹑.
The technical solution of the utility model is achieved in that plate assembly in double-clutch automatic transmission, it is characterized in that: countershaft assembly is fixed on middle plate by the output shaft pressing plate, odd number shelves input shaft assembly and even number shelves input shaft assembly adopt cover axle construction, be that odd number shelves input shaft assembly is arranged in even number shelves input shaft assembly endoporus, and, odd number shelves input shaft assembly and even number shelves input shaft assembly are fixed on middle plate by the input shaft pressing plate, odd number shelves input shaft assembly and the even number shelves input shaft assembly gear by each gear by transmission of power to countershaft assembly.
The utility model good effect is the characteristics such as to have the axial force of bearing a great ﹑ fixedly Ke Kao ﹑ is simple in structure.
The accompanying drawing explanation
Fig. 1 is the utility model structural drawing.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described: as shown in Figure 1, plate assembly in a kind of double-clutch automatic transmission, it is characterized in that: countershaft assembly 6 is fixed on middle plate 5 by output shaft pressing plate 4, odd number shelves input shaft assembly 1 and even number shelves input shaft assembly 2 adopt cover axle construction, be that odd number shelves input shaft assembly 1 is arranged in even number shelves input shaft assembly 2 endoporus, and, odd number shelves input shaft assembly 1 is fixed on middle plate by input shaft pressing plate 3 with even number shelves input shaft assembly 2, the gear of odd number shelves input shaft assembly 1 and even number shelves input shaft assembly 2 by each gear by transmission of power to countershaft assembly 6.
Input shaft pressing plate 3 has limited moving axially of odd number shelves input shaft assembly 1, and output shaft pressing plate 4 has limited moving axially of countershaft assembly 6.
