The assembly structure lowers difficulty of casing sealing, and guarantees the accuracy of transmitting torque and uniformity of load distribution of the reverse gear.
Description
Technical field:
The utility model relates to the eccentric assembly structure of a kind of double-clutch automatic gearbox reverse idler gear, belongs to the automatic gearbox technical field of auto manufacturing.
Background technique:
Along with the fast development of automobile pollution and the rapid increase of amateur driver's quantity, automatic gearbox is just presenting fast development 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, also is present most widely used automatic gearbox.It does not cut off power shfit, has starting, gear shift is smooth-going, but resisting moment is changed advantage such as self adaption.But shortcomings such as it also has complex structure simultaneously, and difficulty is made, and transmission efficiency is low.
Manually fixedly the shaft type gear-shift transmission is the step change driving mechanism, and its advantage is the efficient height, 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 the automatic mechanical transmission of a new generation, it has inherited many advantages such as manual transmission transmission efficiency height, installing space compactness, in light weight, 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 being provided with on the input shaft respectively by strange, even number gear, and clutch C1, C2 replace transferring power to realize gear switch.
During DCT work, vehicle is earlier with certain gear operation, electrical control unit of automatic transmission (TCU) is judged next gear that is about to the work of entering according to the signal of related sensor, because of this gear clutch separation transferring power not also,, mesh this gear in advance so instruction hydraulic control solenoid valve is controlled gear-shifting actuating mechanism very easily, when vehicle operating reaches shift point, only the clutch separation that need will work simultaneously with another clutch, then makes automobile travel with next gear.In gearshift procedure, the power of motor constantly is passed to wheel all the time, so the gearshift procedure of finishing like this is a power shfit.Vehicle has been realized timing, will improve the gear shift travelling comfort greatly, guarantees that also vehicle has good and economic simultaneously, and aspects such as vehicle oil consumption and discharging are made moderate progress.
Summary of the invention:
The purpose of this utility model is to provide a kind of double-clutch automatic gearbox reverse idler gear eccentric assembly structure, because the mating face of idle pulley lid and housing is in speed changer, do not contact, reduced the possibility of cooling and lubricating oil leakage, reduced the difficulty of housing seal with the external world; The accuracy of reverse gear transmitting torque and the uniformity of load distribution have been guaranteed.
The technical solution of the utility model is achieved in that the eccentric assembly structure of a kind of double-clutch automatic gearbox reverse idler gear, by the reverse idler gear lid, and spring pin, the idle pulley that reverses gear, idler shaft, preceding anti-attrition pad and back anti-attrition pad are formed; It is characterized in that: preceding anti-wear gasket sheet is contained in reverse idler gear axle front end, is fixed on idle pulley with spring pin and covers, and reverse idler gear is installed in becomes the idle pulley cap assembly on the idler shaft, and back anti-wear gasket sheet is contained in the rear end of idler shaft in the case of transmission; The reverse idler gear lid is installed in the case of transmission inboard, and reverse idler gear covers the gyration center decentraction that cooperates mounting center and reverse gear shaft with housing.
Good effect of the present utility model is its layout compactness, and case of transmission rigidity and bending intensity height alleviate the advantage of speed changer weight; Because the mating face of idle pulley lid and housing does not contact with the external world in speed changer, has reduced the possibility of cooling and lubricating oil leakage, has reduced the difficulty of housing seal; The accuracy of reverse gear transmitting torque and the uniformity of load distribution have been guaranteed.
Description of drawings

Case of transmission 1, reverse idler gear lid 2, spring pin 3, preceding anti-attrition pad 4, the idle pulley 5 that reverses gear, idler shaft 6, back anti-attrition pad 7 among the figure
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, the eccentric assembly structure of a kind of double-clutch automatic gearbox reverse idler gear, by reverse idler gear lid 2, spring pin 3, the idle pulley 5 that reverses gear, idler shaft 6, preceding anti-attrition pad 4 and back anti-attrition pad 7 are formed; It is characterized in that: preceding anti-attrition pad 4 is contained in reverse idler gear axle 6 front ends, is fixed on the idle pulley lid 2 with spring pin 3, and reverse idler gear 5 is installed in becomes the idle pulley cap assembly on the idler shaft 6, and back anti-attrition pad 7 is contained in the rear end of idler shaft 6 in the case of transmission 1; Reverse idler gear lid 2 is installed in the case of transmission inboard.The gyration center decentraction that cooperates mounting center and reverse gear shaft 6 of reverse idler gear lid 2 and housing 1.
During installation, the reverse idler gear axle 6 of earlier preceding anti-attrition pad 4 being packed into, the back is fixed on the idle pulley lid 2 by spring pin 3, and reverse idler gear 5 is installed in becomes the idle pulley cap assembly again on the idler shaft 6, after will back anti-attrition pad 7 pack in the case of transmission 1, the idle pulley cap assembly is packed in the speed changer.
During work, transmission input shaft passes to reverse idler gear 5 with moment of torsion, and reverse idler gear 5 dallies on idler shaft 6, and gives the corresponding reverse gear of jack shaft with transmission of power, realizes the reverse gear function.
