Abstract
The invention relates to a novel arrangement structure for assembling double-clutch type automatic transmission reverse gear idler wheel eccentric. The arrangement structure is composed of a reverse gear idler wheel cover, a reverse gear idler wheel, an idler shaft, a front antifriction gasket and a rear antifriction gasket; the arrangement structure is characterized in that the front antifriction gasket is arranged on the front end of a reverse gear idler shaft and fixed on the idler wheel cover through a spring pin; the reverse gear idler wheel is arranged on the idler shaft so as to form an idler wheel cover assembly, and the rear antifriction gasket is arranged on the rear end of the idler shaft arranged in a transmission shell; and the reverse gear idler wheel cover is arranged at the inner side of the transmission shell, a mating installation centre of the reverse gear idler wheel cover and the shell and a rotation center of the reversing shaft are not concentric. The arrangement structure provided by the invention has the advantages of reducing the possibility of cooling lubricating oil leakage, reducing the sealing difficulty of the shell, guaranteeing the torsion transferring accuracy of the back gear and the load distribution uniformity.
Description
Technical field:
The present invention relates to the eccentric assembling of a kind of novel double-clutch automatic transmission reverse idler gear layout, belong 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 that efficient is high, and cost is low, and mature production technology is widely used in China at present.Shortcoming is a 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 high, the many advantages such as installing space is compact, in light weight, low price of manual transmission transmission efficiency; 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 by strange, even number gear respectively with input shaft on two clutch C1, C2 being provided be connected, clutch C1, C2 replace transferring power to realize gear switch.
During DCT work, with certain gear operation, electrical control unit of automatic transmission (TCU) is judged next gear that is about to the work of getting into according to the signal of related sensor to vehicle earlier; 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; The clutch separation that only need will work simultaneously with another clutch, then makes automobile go with next gear.In gearshift procedure, the power of motor constantly is passed to wheel all the time, so the gearshift procedure of accomplishing like this is a power shfit.Vehicle implementation timing, will improve the gear shift travelling comfort greatly, simultaneously guarantee that also vehicle has good and economic, aspects such as vehicle oil consumption and discharging are made moderate progress.
Summary of the invention:
The object of the present invention is to provide the eccentric assembling of a kind of novel double-clutch automatic transmission reverse idler gear layout; 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.
Technological scheme of the present invention is achieved in that the eccentric assembling of a kind of novel double-clutch automatic transmission reverse idler gear layout, by the reverse idler gear lid, and spring pin, the idle pulley that reverses gear, idler shaft, preceding anti-attrition pad is formed with back anti-attrition pad; 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 invention is that its layout is compact, and case of transmission rigidity and bending intensity are high, 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.

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 present invention is done further description:
As shown in Figure 1, the eccentric assembling of a kind of novel double-clutch automatic transmission reverse idler gear layout, by reverse idler gear lid 2, spring pin 3, the idle pulley 5 that reverses gear, idler shaft 6, preceding anti-attrition pad 4 is formed with back anti-attrition pad 7; 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; Earlier with the preceding anti-attrition pad 4 reverse idler gear axle 6 of packing into, the back is fixed on the idle pulley lid 2 through 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.
