Background technique
Along with more and more receiving people, the automobile of automatic catch likes the restriction with national specified discharge standard; Double-clutch automatic gearbox DCT (Dual Clutch Transmission) is more and more paid attention to by people; And have the double-clutch automatic gearbox of volume production now owing to will realize self shifter control, what adopt mostly is the hydraulic control gear shift control, increase oil circuit and piston cylinder on housing; Walk always to promote moving of piston through oil circuit in the control system; Because the piston of housing piston cylinder links to each other with selector fork, to move so drive shifting fork bar, the final completion shifted gears.
At present, the wet type double-clutch speed changer of existing volume production all is through the self shifter that oil circuit and piston cylinder are realized is set on housing.This method has increased the processing technology of housing greatly, has increased the cost of speed changer.And this method also increased the difficulty of the sealing of oil circuit between hydraulic module and the housing, is easy to cause leakage of oil; Because double-clutch speed changer will satisfy shifting power and not interrupt, just need the reduction gearshift time, but, increased the length of oil circuit because hydraulic oil will pass through the oil circuit on the housing, will influence the gearshift time, power interruption in the time of possibly causing gearshift.
The model utility content
The purpose of the utility model provides a kind of gearshift actuating device of double-clutch speed changer, causes deficiencies such as leakage of oil and processing technology complicacy easily with what the wet type double-clutch speed changer that overcomes the existing technology volume production existed.
The purpose of the utility model is to realize through following technological scheme:
A kind of gearshift actuating device of double-clutch speed changer; Comprise hydraulic valve and shift fork, said hydraulic valve is through the fixing some piston rods of clamping bolt, and the two ends of piston rod are respectively equipped with piston; The inside of piston rod is provided with left oil circuit and right oil circuit; One end of a left side oil circuit and right oil circuit passes two end faces of piston rod respectively, and with piston rod and two pistons between the cavity that forms be communicated with, the other end of left oil circuit and right oil circuit is connected with oil inlet hole on the hydraulic valve; The middle part of piston outer wall has annular groove and the annular groove card that is positioned on two piston outer walls on the same piston rod has shift fork; One side of shift fork is provided with the gearshift groove, and this gearshift groove matches with gearshift positioning seat on being fixed on case of transmission or valve body, and the bottom of shift fork is welded with magnet near the position of annular groove.
Constitute piston cylinder one and piston cylinder two between two pistons at said piston rod and its two ends respectively.
The beneficial effect of the utility model is: self shifter that oil circuit and piston cylinder realize being set through oil circuit and piston cylinder on the cancellation double-clutch automatic gearbox housing on the housing, reduce the cost of production of double-clutch automatic gearbox; Reduce the processing technology of housing; In addition selector fork is directly linked to each other with hydraulic module, reduce the risk and the gearshift performance that increases double-clutch speed changer of double-clutch automatic gearbox leakage of oil; Save declutch shift shaft, reduced the volume of speed changer greatly; Shorten the oil circuit that the control shift fork moves, increased shift speed; Not be used in oil circuit and piston cylinder are set on the housing, reduced the processing technology of housing, easier for installation; Reduced the risk sternly do not brought because of housing seal.
