The content of the invention
The technical problems to be solved by the invention, which are to provide one kind, can reliably carry out P gear locking controls, automate journey Spend high P gear latching control devices.
In order to solve the above technical problems, the technical scheme is that:A kind of P keeps off latching control device, including with control The parking valve control oil circuit of the parking valve connection of halting mechanism action, the parking valve control oil circuit, which is equipped with, controls the parking Valve controls the control valve of oil circuit break-make, and the control valve is controlled by Gear shift operation mechanism.
As preferable technical solution, the Gear shift operation mechanism is knob gearshift.
As preferable technical solution, the control valve is solenoid valve.
As preferable technical solution, the control valve is reversal valve, and control is connected with the parking valve control oil circuit Second control oil circuit of the reversal valve break-make, described second controls on oil circuit successively equipped with pressure reducing valve and pressure control switch electricity Magnet valve, the break-make of the second control oil circuit described in the pressure control switch solenoid valve control, along the described second control oil circuit, fluid The pressure control switch solenoid valve is flow to after the pressure reducing valve.
As preferable technical solution, the pressure control switch solenoid valve is normal high switch electromagnetic valve.
As preferable technical solution, fluid enters parking valve control oil circuit and the second control oil after oil pump through filter Road.
As preferable technical solution, further include when P keeps off and unlocking, the locking system of parking valve described in locking.
As preferable technical solution, the locking system includes can the lock pin of parking valve described in clamping and control locking The lock-up solenoid valve of pin action.
By adopting the above-described technical solution, a kind of P gears latching control device, including stayed with what control halting mechanism acted The parking valve control oil circuit of car valve connection, the parking valve control oil circuit, which is equipped with, controls the parking valve control oil circuit break-make Control valve, the control valve are controlled by Gear shift operation mechanism;Operation knob gearshift, when vehicle is in P gears, pressure control Switch electromagnetic valve is powered, and disconnects the second control oil circuit, and reversal valve is in initial position at this time, and fluid can not control oil through parking valve Road enters parking valve, and parking valve is in initial position, and halting mechanism is in P gears;When vehicle need unlock P gear, knob is shifted gears When the knob of device is threaded to D/R/N positions, control electric current, the power-off of pressure control switch solenoid valve are sent, the second control oil circuit connects Logical, reversal valve movement, parking valve controls oil communication, and fluid enters parking valve through parking valve control oil circuit, and parking valve left end is built Vertical oil pressure, parking valve, which is promoted, to move right, and after being moved to maximum displacement, lock-up solenoid valve is powered, and lock pin moves down, by parking Valve pins, and plays safety effect, and P gears are in the unlocked state at this time;P gear locking controls, the degree of automation can reliably be carried out Height, securely and reliably.
Brief description of the drawings
Principle schematic when Fig. 1 is P gears locking in the embodiment of the present invention;
Principle schematic when Fig. 2 is P gears unlock in the embodiment of the present invention.
Embodiment
As depicted in figs. 1 and 2, a kind of P gears latching control device, including the parking valve 2 acted with control halting mechanism 1 connect The parking valve control oil circuit 3 connect, the parking valve control oil circuit 3 are equipped with the control for controlling parking valve control 3 break-make of oil circuit Valve 4 processed, the control valve 4 are controlled by Gear shift operation mechanism.
The Gear shift operation mechanism is knob gearshift.
The control valve is solenoid valve.
Preferably, the control valve 4 is reversal valve, and the control reversal valve 4 is connected with the parking valve control oil circuit 3 The second of break-make controls oil circuit 5, and pressure reducing valve 6 and pressure control switch solenoid valve 7 are equipped with successively on the second control oil circuit 5, The pressure control switch solenoid valve is normal high switch electromagnetic valve, and the pressure control switch solenoid valve 7 controls second control The break-make on liquefaction road 5, along the described second control oil circuit 5, fluid flow to the pressure control switch electromagnetism after the pressure reducing valve 6 Valve 7.Since the action of parking valve needs larger oil pressure, general solenoid valve can not be met the requirements as control valve, pass through setting Second control oil circuit, after pressure reducing valve depressurizes, the pressure control switch solenoid valve control on the second control oil circuit is as the control The commutation valve events of valve processed, can reliably carry out P gear locking controls, and the degree of automation is high.
Fluid enters parking valve control oil circuit 3 and second through filter 9 after oil pump 8 and controls oil circuit 5.
Further include when P keeps off and unlocking, the locking system of parking valve described in locking.
