The big end of operating rock arm push rod is installed in the brake activation valve intracoelomic cavity, can endwisely slip along the brake activation valve intracoelomic cavity; Small end is installed in to be handled in the shifting block spring perch inner chamber, can shifting block spring perch inner chamber endwisely slips and the two is by the sealing of O RunddichtringO along handling; The operating rock arm push rod links to each other by sealing preloading spring elasticity with manipulation shifting block spring perch.
The operating rock arm axle is rigidly connected with handling shifting block one end, and manipulation is dialled 7 other ends and is installed in the corresponding inner chamber of operating rock arm push rod.
Good effect of the present utility model mainly is: have the trailer compressed air brake and handle priority function.This air brake valve is fixed in operating rock arm on the hydraulic braking controlled pedal rocking arm, and by the reasonably optimizing design, guarantees to make air brake valve action earlier when handling, and moves behind the hydraulic brake valve, adopts the mode of physics to realize the function that compressed air brake is preferential.This air brake valve makes full use of the characteristics of compression air brake, has adopted the formula maneuverability pattern of dying, and the response action is fast, reflection is sensitive.
Description of drawings
Accompanying drawing 1 is the utility model used with tractor preferential air brake valve structural representation of formula trailer of dying.
Fig. 2 is the utility model used with tractor preferential air brake valve A-A of formula trailer cross-sectional view of dying.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.Controlled pedal head 1 is rigidly attached to braking valve body 2 tops, forms the brake activation valve component; Again operating rock arm 3, operating rock arm axle 4 are rigidly connected with main car hydraulic braking controlled pedal arm 5, form the brake pedal component; The brake activation valve component can be connected with the brake pedal component by operating rock arm axle 4 and can relatively rotate, and when air brake valve was not worked, the two nothing relatively rotated.
Handle shifting block spring perch 8 and be installed in braking valve body 2 inner chambers, the two is by the sealing of O RunddichtringO; Valve core case 11 big ends are installed in braking valve body 2 inner chambers, and the two seals by the O RunddichtringO, and can slide vertically; Small end is installed in to be handled in shifting block spring perch 8 inner chambers, and can slide vertically; Handle between shifting block spring perch 8 and the valve core case 11 and linked to each other by damping spring 10 elasticity, the two can slip vertically in braking valve body 2 inner chambers; Rear side housing 12 is installed in braking valve body 2 inner chambers, and the two is fixed in braking valve body 2 inner chamber relevant positions by the sealing of O RunddichtringO and with inner shield ring; Spool component 14 small ends are installed in rear side housing 12 guide grooves, can endwisely slip along rear side housing 12 guide grooves, and the two links to each other with spool preloading spring 13 elasticity by preloading spring catch 15; Operating rock arm push rod 6 big ends are installed in braking valve body 2 inner chambers, can endwisely slip along braking valve body 2 inner chambers; Small end is installed in to be handled in shifting block spring perch 8 inner chambers, can shifting block spring perch 8 inner chambers endwisely slip and the two is by the sealing of O RunddichtringO along handling; Operating rock arm push rod 6 links to each other by sealing preloading spring 9 elasticity with manipulation shifting block spring perch 8; Handle shifting block 7 one ends and operating rock arm axle 4 and be rigidly connected, can drive 7 generations of manipulation shifting block during 4 rotations of operating rock arm axle and radially rotate along operating rock arm axle 4; Handle shifting block 7 small ends and be installed in the operating rock arm push rod 6 corresponding inner chambers, can drive operating rock arm push rod 6 by stirring of manipulation shifting block 7 and endwisely slip along braking valve bodies 2 inner chambers; Promotion by operating rock arm push rod 6 can drive spool component 14 and endwisely slip along rear side housing 12 guide grooves, when air brake valve is not worked, leave the gap between spool component 14 and valve core case 11 intermediate throughholes, the air valve normal open, the action of total system brakeless, trac. transportation unit is in the cruising state.
Controlled pedal head 1 is rigidly connected with braking valve body 2, forms the brake activation valve component; Operating rock arm 3, operating rock arm axle 4 are rigidly connected with main car hydraulic braking controlled pedal arm 5, form the brake pedal component; The motion of glancing impact brake activation valve component, because brake activation valve component design actuating force is little than trac. main frame hydraulic braking actuating force, therefore, by operating rock arm axle 4 can with the brake pedal component relative to producing rotating of certain angle, operating rock arm axle 4 is rigidly connected with manipulation shifting block 7, can drive 7 generations of manipulation shifting block during 4 rotations of operating rock arm axle and radially rotate, can drive operating rock arm push rod 6 by stirring of manipulation shifting block 7 and endwisely slip along braking valve bodies 2 inner chambers along operating rock arm axle 4; Operating rock arm push rod 6 promotes spool component 14 and endwisely slips along rear side housing 12 guide grooves, make gap-closing, sealing between spool component 14 and valve core case 11 intermediate throughholes, thereby make the trailer air braking system produce braking maneuver, make trailer brake, residual compression air in the system enters operating rock arm push rod 6 middle exhaust passages by the gap between spool component 14 and the operating rock arm push rod 6 and is discharged in the atmosphere, has further improved the reactivity worth of air brake valve; In the process that the trailer air brake valve moves, brake-pressure is set up in main car hydraulic braking gradually, produces braking maneuver, because of the action earlier of trailer compression air brake, so guaranteed the safety of whole unit braking, has finished the braking maneuver of trac. transportation unit.
During brake off, entire mechanism is return under the effect of damping spring 10 and sealing preloading spring 9, reaches the cruising state, finishes braking brake off state.
