Description
Technical field
The utility model relates to a kind of idle pulley gasket construction that reverses gear being applied to double-clutch automatic transmission, belongs to the automatic gearbox 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.
Double-clutch automatic transmission reverse gear idle pulley running time can make it to produce end contact with housing because of responsive to axial force, therefore need design two anti-attrition pads to prevent housing from wearing and tearing.Design due to current anti-attrition pad does not have the limitation function of circumferencial direction, causes anti-attrition pad to rotate with idle pulley and causes housing to wear and tear.
Summary of the invention
The purpose of this utility model is to provide a kind of idle pulley gasket construction that reverses gear being applied to double-clutch automatic transmission, and it adopts new anti-wear gasket chip architecture, efficiently solves the problems referred to above, structure is simple, arrangement convenience, be easy to processing and cost low.
The technical solution of the utility model is achieved in that the idle pulley gasket construction that reverses gear being applied to double-clutch automatic transmission, it is characterized in that: the idle pulley that reverses gear is connected on idler shaft, and the idle pulley that reverses gear engages with reverse gear driving gear and driven gear respectively; Idler shaft is fixed on housing by spring pin, and idle pulley both sides of reversing gear are respectively equipped with anti-attrition pad, anti-attrition pad increases punching press bending structure and coordinates with die casting for shell groove structure.
Good effect of the present utility model is that the housing in order to prevent the relative movement of idle pulley and housing from causing weares and teares, and idle pulley both sides devise anti-attrition pad respectively, because gear can drive anti-attrition pad to rotate together, can cause the wearing and tearing of housing and anti-attrition pad equally; Have that structure is simple, arrangement convenience, be easy to processing and the feature such as cost is low.
Accompanying drawing explanation
Fig. 1 is the utility model cross-sectional view.
Fig. 2 is structural drawing of the present utility model.
Fig. 3 is spring pin partial schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described: as Figure 1-3, be applied to the idle pulley gasket construction that reverses gear of double-clutch automatic transmission, it is characterized in that: the idle pulley 2 that reverses gear is connected on idler shaft 3, the idle pulley 2 that reverses gear engages with reverse gear driving gear and driven gear respectively; Idler shaft 3 is fixed on housing 1 by spring pin 4, and idle pulley 2 both sides of reversing gear are respectively equipped with anti-attrition pad 5, anti-attrition pad 5 increases punching press bending structure and coordinates with housing 1 die casting groove structure.
Because the idle pulley 2 that reverses gear can drive anti-attrition pad 5 to rotate together, especially when reversing gear idle pulley bearing load, the anti-attrition pad 5 in its Impact direction side can relatively rotate with housing 1 and wear and tear equally.Have employed in Fig. 3 and anti-attrition pad 5 increase A place die casting for shell groove structure in punching press bending structure and Fig. 2, both with the use of, avoid the appearance of the problems referred to above.
