In the lockable mechanism of above-mentioned automatic gear changer, vertically, described locking hole is positioned at the top of lock groove, and described lock groove is strip and lower ending opening.Locking is directive, and the push rod of solenoid valve is embedded in lock groove, and push rod can slide along lock groove, and gear can be lockable when pushing R shelves from D shelves, N shelves, namely can not shift gears, and gear can push D shelves from N shelves and can not be lockable.
In the lockable mechanism of above-mentioned automatic gear changer, the madial wall semicircular in shape on described lock groove top, the madial wall of described lock groove bottom is curved.The circular arc that two madial walls of lock groove bottom are is the center of circle with the center of main shaft, this kind of structure, makes the push rod of solenoid valve slide in lock groove smoothly.
In the lockable mechanism of above-mentioned automatic gear changer, described solenoid valve wears and is connected on scaffold, and described solenoid valve is connected mutually by scaffold and upper bracket.Scaffold, as carrier, improves the installation firmness of solenoid valve.
In the lockable mechanism of above-mentioned automatic gear changer, described scaffold is cross, and described solenoid valve is positioned at the infall of scaffold cross.Improve the installation firmness of solenoid valve.
Compared with prior art, the lockable mechanism of the automatic gear changer that the utility model provides, when driving, when brake petal unclamps, solenoid valve no electric circuit, the push rod of solenoid valve stretches out, the push rod of solenoid valve is embedded in lock groove, make operating stem can not be allocated to R shelves or P shelves from D shelves, automatic transmission can not be damaged, automatic transmission long service life; Vehicle stop determining brake petal unclamp time, the push rod of solenoid valve stretches out and is embedded in locking hole, and vehicle can not be run when stay longer.
