The course of work of the present utility model is as follows：
After Diesel engine starts, hydraulic pump 1 is started working, and hydraulic system sets up oil pressure, torque converter oil liquid pressure
Acting on the K mouths of multiple directional control valve 4 makes multiple directional control valve 4 commutate, and makes its oil inlet P mouthful be communicated for B mouthfuls with working hole, is done for driving
It is good to prepare.Now, vehicle is in parking braking state.When the operation handle of manually operated braking valve for vehicle 3 makes it commutate, it is made
A mouthfuls with working hole of oil inlet P mouthful is communicated, and now hydraulic pump 1 inhales hydraulic oil liquid from hydraulic oil container 10 by oil absorption filter 12
Enter and export out again, hydraulic oil liquid flows to the P of braking valve for vehicle 3 by the high pressure filter filtering of high pressure filter integrated package 2
Mouthful, unnecessary hydraulic oil liquid can flow back to fuel tank by the system safety valve off-load on high pressure filter integrated package 2, pump out what is come
High-pressure and hydraulic fluid reaches front-rear axle EPB solution braking pressure by the pressure-reducing valve decompression inside braking valve for vehicle 3
Power.Hydraulic oil liquid after decompression flows to the oil inlet P mouthful of multiple directional control valve 4 by A mouthfuls of the working hole of braking valve for vehicle 3, now
The oil inlet P mouthful of multiple directional control valve 4 and B mouthfuls of the working hole of multiple directional control valve 4 are communicated, P mouth of the hydraulic oil liquid from multiple directional control valve 4
B mouthfuls are flowed to, then flows to pressure measurement and crosses liquid block 5, the hydraulic oil liquid that A, B, C, D mouth of liquid block 5 are crossed by pressure measurement flows to a propons left side respectively
Side brake 7, back axle left hand brake device 6, propons right hand brake 8, the parking braking mouthful of back axle right hand brake 9, make four
The parking braking of brake is in solution on-position, and vehicle can be with normally travel.
, can be with manually operated parking when down-hole trackless needs temporary parking but does not need diesel motor flameout
The operation handle of brake valve 3 makes it commutate, now, and A mouthfuls of the working hole of braking valve for vehicle 3 is communicated with oil return inlet T mouthful, front-rear axle
EPB cavity hydraulic oil liquid is squeezed out under spring force, successively crosses liquid block 5, multiple directional control valve by pressure measurement
The A mouths of 4 B mouths to P mouthfuls, braking valve for vehicle 3 arrive T mouthfuls, are flowed back to finally by return filter 11 in fuel tank, 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 is stopped, and hydraulic pump 1 and torque converter pump stop work
Make, now, K mouthfuls of the control mouth of multiple directional control valve 4 makes the inside valve core of the spool valve commutation of multiple directional control valve 4, make its time without oil pressure
B mouthfuls with working hole of T mouthfuls of hydraulic fluid port is communicated, and the EPB 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 warp of the A mouths of liquid block 5, back axle left hand brake device 6 by 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 by pressure measurement
The hydraulic oil liquid of device 9 crosses the D mouths of liquid block 5 by pressure measurement, flows to B mouthfuls of the working hole of multiple directional control valve 4, the B mouths of multiple directional control valve 4
Communicated with T mouthfuls, the parking braking cavity hydraulic oil liquid in front-rear axle brake flows back to oil from the oil return inlet T mouthful of multiple directional control valve 4
Friction plate locking under the action of the spring in case, front-rear axle brake, front-rear axle brake is completely in parking braking state,
Storing cycle is safe and reliable.
Using flame-out brakes of the present utility model, regardless of whether parking pulls parking brake, no matter whether vehicle is parked in
Acclive place, vehicle stops under flame-out brakes, is in complete parking on-position, vehicle after vehicle stall automatically
It is safe and reliable.
