Mouthful, then flow to pressure measurement and cross liquid block 5, the hydraulic oil liquid that A, B, C, D mouth of liquid block 5 is crossed through pressure measurement flows respectively propons left hand brake
Device 7, back axle left hand brake device 6, propons right hand brake 8, the parking braking mouth of back axle right hand brake 9, make four brakes
Parking braking in solution on-position, vehicle can be with normally travel.
When down-hole trackless needs temporary parking but does not need diesel motor flameout, can be with manual operation parking
The operation handle of brake valve 3 makes it commutate, and now, the working hole A mouths of braking valve for vehicle 3 are communicated with oil return inlet T mouth, front-rear axle
Parking brake cavity hydraulic oil liquid is squeezed out under spring force, successively crosses liquid block 5, multiple directional control valve through pressure measurement
4 B mouths to P mouths, braking valve for vehicle 3 A mouths to T mouths, fuel tank is flowed back to finally by return filter 11, in front-rear axle brake
Friction plate locking under the action of the spring, now, front-rear axle brake is completely in parking braking state.
After down-hole trackless switch-off, Diesel engine quits work, and hydraulic pump 1 and torque converter pump stop work
Make, now, the control mouth K mouth of multiple directional control valve 4 makes the inside valve core of the spool valve commutation of multiple directional control valve 4 without oil pressure, makes its time
Hydraulic fluid port T mouths are communicated with working hole B mouths, and the parking brake cavity hydraulic oil liquid of front-rear axle is extruded under spring force
Go out, the hydraulic oil liquid of propons left hand brake device 7 crosses the hydraulic oil liquid Jing of the A mouths of liquid block 5, back axle left hand brake device 6 through pressure measurement
Cross that the B mouths of liquid block 5 are crossed in pressure measurement, the hydraulic oil liquid of propons right hand brake 8 crosses C mouths, the back axle right side brake of liquid block 5 through pressure measurement
The hydraulic oil liquid of device 9 crosses the D mouths of liquid block 5 through pressure measurement, flows to the working hole B mouths of multiple directional control valve 4, the B mouths of multiple directional control valve 4
Communicate with T mouths, the parking braking cavity hydraulic oil liquid in front-rear axle brake flows back to oil from the oil return inlet T mouth of multiple directional control valve 4
Case, the locking under the action of the spring of the friction plate in front-rear axle brake, front-rear axle brake is completely in parking braking state,
Storing cycle is safe and reliable.
Using the flame-out brakes of the present invention, regardless of whether parking pulls parking brake, no matter whether vehicle has been parked in slope
Where degree, vehicle stops under flame-out brakes, is in complete parking on-position, vehicle safety after vehicle stall automatically
It is reliable.
