Description
Technical field
The utility model relates to a kind of chain support block structure 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).
On automobile, realize self-shifting speed changer is hydraulic mechanical type automatic transmission, and being called for short AT, is also current most widely used automatic gearbox.It does not cut off power gear shifting, has starting, smooth gear shifting, can the advantage such as self adaption to resisting moment change.But it also has complex structure simultaneously, difficult manufacture, the shortcomings such as transmission efficiency is low.
Manually fixing shaft type gear-shift transmission is step change driving mechanism, and its advantage is that efficiency is high, and cost is low, mature production technology, is widely used at present in China.Shortcoming is gearshift difficulty, and power interruption during gearshift requires that pilot control is skilled, so people expect that it can realize automation.Computer Control Technology makes this gear realize self shifter becomes possibility.Double-clutch automatic transmission (DCT) is the automatic mechanical transmission of a new generation, many advantages such as it inherits that manual transmission transmission efficiency is high, installing space is compact, lightweight, low price, fundamentally solve the cut-out power gear shifting problem that electric control mechanical type automatic speed variator exists, drastically increase shifting comfort, ensure that vehicle has good power character and gear shifting characteristic.
In double-clutch automatic transmission, speed changer each gear driving gear is connected with two clutches C1, C2 that input shaft is arranged respectively by odd, even several gear, and clutch C1, C2 replace transferring power and switch to realize gear.
During DCT work, vehicle first runs with certain gear, electrical control unit of automatic transmission (TCU) judges according to the signal of related sensor next gear being about to the work of entering, because of this gear clutch separation also non-transferring power, therefore instruction hydraulic pressure controlling solenoid valve controls gear shifting actuating mechanism very easily, engages this gear in advance, when vehicle operating reaches shifting points, only need the clutch separation that will working, another clutch is engaged simultaneously, then make automobile travel with next gear.In shift process, the power of motor is constantly passed to wheel all the time, so the shift process completed like this is power gear shifting.Vehicle achieves power gear shifting process, will improve shifting comfort greatly, also ensures that vehicle has good Economy simultaneously, the aspect such as vehicle oil consumption and discharge is made moderate progress.
The chain support block of double-clutch automatic transmission mainly plays effect that is spacing and guiding, chain and sprocket wheel need certain pretightening force when assembling, when working under high rotating speed, high moment of torsion, chain can produce between adjacent two sprocket wheels beats, sprocket wheel spacing is larger, jerk value is larger, adopts chain support block structure effectively can avoid the problems referred to above.
Summary of the invention
The purpose of this utility model is to provide a kind of chain support block structure of double-clutch automatic transmission, and it has into this Di ﹑ Gong and makes the features such as Ke Kao ﹑ structure is simple.
The technical solution of the utility model is achieved in that a kind of chain support block structure of double-clutch automatic transmission, it is characterized in that: input sprocket is arranged in below double clutch, input sprocket and the concrete position of double clutch triangular in shape, chain is around on input sprocket and double clutch, chain support block totally three, chain support block end face is aluminum frame bottom surface is rubber surface, the rubber surface of chain support block is fixedly connected with case of transmission by bolt, the corresponding chain of end face of the aluminum frame of chain support block, concrete corresponding position is leg-of-mutton three limits that chain is formed around input sprocket and double clutch.
The utility model good effect is that Ju has the mono-﹑ of Jie structure Jian to be easy to the features such as this Di of An Zhuan ﹑ Cheng ﹑ reliable operation.
Accompanying drawing explanation
Fig. 1 is structural drawing of the present utility model.
Fig. 2 is chain support block structure figure of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described: as Fig. 1, shown in 2, a kind of chain support block structure of double-clutch automatic transmission, it is characterized in that: input sprocket 2 is arranged in below double clutch 1, input sprocket 2 is triangular in shape with the concrete position of double clutch 1, chain 3 is around on input sprocket 2 and double clutch 1, chain support block 4 totally three, chain support block 4 end face is aluminum frame A bottom surface is rubber surface B, the rubber surface B of chain support block 4 is fixedly connected with case of transmission by bolt 5, the corresponding chain 3 of end face of the aluminum frame A of chain support block 4, concrete corresponding position is leg-of-mutton three limits that chain 3 is formed around input sprocket 2 and double clutch 1.
Engine power is passed to double clutch 1 by chain 3 by input sprocket 2, and chain 3 can produce in the process of transmitting torque beats, and adopts three chain support block 4 structures spacing to chain 3, effectively can avoid the problems referred to above, ensures the smoothness that chain 3 operates.Chain support block 4 is fixed by bolt 5 and case of transmission, and chain support block is made up of aluminum frame A and rubber B, adopts sulfuration process.This design proposal Ju has the mono-﹑ of Jie structure Jian to be easy to the features such as this Di of An Zhuan ﹑ Cheng ﹑ reliable operation.
