Description

The block selecting automatic traveling crane system of vehicle
Technical field
The present invention relates to a kind of vehicle, and in particular to a kind of block selecting automatic traveling crane system of vehicle.
Background technology
Vehicle typically first selects forward gear, then releases stopping brake in normally travel state when driver is open to traffic Step on the gas again, when that need to stop, throttle can be unclamped and select neutral and braked, for the frequent conversion operating location of need and not With the distance between operating location and shorter working truck, during operation, because its operating range is very short, need again frequent Parking, continually operates throttle, gear and braking for driver, operation is very inconvenient, therefore design one kind can be just Normal transport condition is switched over job state and block selecting can automatic traveling crane, the block selecting of easy to operate vehicle in job state Automatic traveling crane system is very necessary.
The content of the invention
It can be switched over and in job state in normally travel state and job state it is an object of the invention to provide one kind When block selecting when can automatic traveling crane, the block selecting automatic traveling crane system of easy to operate vehicle.
To achieve these goals, the technical scheme is that：
A kind of block selecting automatic traveling crane system of vehicle, including fuel tank, filter, hydraulic pump, safety valve, block selecting valve, retreating gear from Clutch, forward gear clutch, accelerator pedal mechanism, throttle master cylinder, lubricating cup, throttle hydraulic cylinder, parking brake, shut-down hydraulic cylinder With stopping brake valve, the parking brake includes moving plate and still, and its innovative point is：Also include the first magnetic valve, second Magnetic valve and controlling organization；
The oil inlet of the hydraulic pump is connected by filter with fuel tank, the oil-out of hydraulic pump by two oily passages respectively with choosing The oil inlet P mouthful for keeping off valve is connected with 2 mouthfuls of the oil inlet P of the second magnetic valve, and A mouthfuls of the execution mouthful of block selecting valve is distinguished by three oily passages Connected with 1 mouthful of the oil inlet P of forward gear clutch, the oil inlet P mouthful of the first magnetic valve and the second magnetic valve, the execution of block selecting valve B mouthfuls of mouth is connected with retreating gear clutch；
A mouthfuls of the execution mouth of second magnetic valve is connected with the oil inlet P mouthful of stopping brake valve, the execution mouthful A of stopping brake valve Mouth is connected with the rod chamber of shut-down hydraulic cylinder, and the piston rod of shut-down hydraulic cylinder is fixedly connected with the moving plate of parking brake；
The piston rod of the throttle master cylinder is fixedly connected with the gas pedal of accelerator pedal mechanism, the lubricating cup and throttle master cylinder Rodless cavity is connected and setting height(from bottom) of the lubricating cup on vehicle is higher than setting height(from bottom) of the throttle master cylinder on vehicle, the throttle master cylinder Rodless cavity connected with the rod chamber with throttle hydraulic cylinder, the piston rod of the throttle hydraulic cylinder and the accelerator rod of engine are solid Fixed connection；
A mouthfuls of the execution mouth of first magnetic valve is connected with the rod chamber of throttle hydraulic cylinder, the terminals of first magnetic valve Electrically connected with the terminals of the second magnetic valve with controlling organization.
The controlling organization includes switch and power supply, the switch and power electric connection.
The controlling organization includes button switch and master controller, and the button switch is electrically connected with master controller, button During switch closure electricity condition is being obtained by the terminals of the magnetic valve of main controller controls first and the terminals of the second magnetic valve.
Drainback passage is provided between the oil-out and fuel tank of the hydraulic pump, safety valve is arranged in the drainback passage.
Benefit of the invention is that：（1）, because the switch when controlling organization is in open mode or drives the button of controlling organization Close in open mode, the terminals of the terminals of the first magnetic valve and the second magnetic valve are in power failure state, and now vehicle is just Normal transport condition, when controlling organization switch is in closure state or makes the button switch of controlling organization in closure state, the first electricity The terminals of the terminals of magnet valve and the second magnetic valve electricity condition, now vehicle is in job state, therefore vehicle can be Normally travel state is switched over job state；（2）, due to when vehicle need to be in job state, the wiring of the first magnetic valve End and the terminals of the second magnetic valve are obtaining electricity condition, and the oil inlet P mouthful of the first magnetic valve is communicated with performing mouth A mouthfuls, and second 1 mouthful of the oil inlet P of magnetic valve is communicated with performing mouth A mouthfuls, and block selecting valve need to be only operated when driver is open to traffic, makes entering for block selecting valve P mouthfuls of hydraulic fluid port is communicated with performing mouth A mouthfuls, vehicle is hung over forward gear；The pressure oil in hydraulic pump can also enter throttle hydraulic pressure simultaneously The rod chamber of cylinder, the piston rod of throttle hydraulic cylinder drives the accelerator rod of engine to move and open out；Simultaneously in hydraulic pump Pressure oil can also enter shut-down hydraulic cylinder rod chamber, make shut-down hydraulic cylinder piston rod drive parking brake moving plate with it is quiet Piece is separated, and Parking braking release, vehicle is started running.Therefore block selecting valve need to only be operated, you can select forward gear, open out and releasing Stopping brake, i.e., can automatic traveling crane, easy to operate during block selecting in job state.When that need to stop, block selecting valve only need to be operated, is made A mouthfuls of the execution mouthful of block selecting valve and B mouthfuls of mouth of execution are communicated with fuel tank 1, and vehicle is hung in neutral；Throttle hydraulic cylinder is in spring simultaneously In the presence of piston rod drive the accelerator rod return of engine, i.e. no longer open out；While work of the shut-down hydraulic cylinder in spring Under, the pressure oil in shut-down hydraulic cylinder 14 returns to fuel tank, the piston rod of shut-down hydraulic cylinder is driven the moving plate of parking brake Combined with still, vehicle braking, therefore need to only operate block selecting valve, you can hung neutral, no longer open out and braked, that is, making It is easy to operate during industry state.
Below in conjunction with accompanying drawing and the embodiment provided, the present invention is further illustrated.
