Abstract
The utility model provides a light semi trailer parking brake device relating to a brake arm, a swing rod, as well as a pulling fork, a steel wire pulling rod, a steel wire and a brake arm pulling fork that are connected between the brake arm and the swing rod; wherein, one end of the swing rod is hung with a tension spring that is hung on a pulling rod support fixed on a frame through a spring pulling rod; the frame is fixed with a performing air cell having a pushing rod that is hinged with one end of the swing rod; an air circuit of the performing air cell is communicated with an air storing canister through a performing air tube circuit and a three way controlling switch. The parking brake device can check the air pressure of the air storing cabinet of a brake driving source during running; during running, in case that the air pressure of a brake system is decreased, the device can brake automatically, thereby preventing the semi trailer from losing control and increasing the safety performance of running; and the special parking brake device makes the performance of the brake system more excellent. Besides, the utility model has the advantages of a simple structure, high brake precision, safety and reliability.
Description
Technical field:
The utility model relates to a kind of later-model light semi-trailer holding brake device.
Background technology:
Present most of superimposed trailer manufacturer generally adopts traditional screw mandrel to draw the device of swing arm, directly with manually carrying out braking during standstill, can not lose compressed-air actuated emergency situation to brake system in driving and brake, and is prone to accidents.
Summary of the invention:
The purpose of this utility model provides a kind of light semi-trailer holding brake device, and in the vehicle ' process, if when the service braking system internal gas pressure reduces, this device can be braked automatically, avoids the superimposed trailer get out of hand, improves the traffic safety performance.Behind trouble removal, when air pressure is raised to normal working, just remove the braking of this device.
The purpose of this utility model realizes as follows: this light semi-trailer holding brake device, draw fork, steel rope pull bar, steel rope, the brake control lever that relate to brake control lever, fork and be connected between the two draw fork, the other end at fork hangs with extension spring, extension spring hangs on the rob support that is fixed on vehicle body by the spring pull bar, on vehicle body, be fixed with the execution air chamber, the push rod of carrying out air chamber is hinged on this end of fork, and the gas circuit of carrying out air chamber is communicated with air receiver by carrying out air pipe and three-dimensional master cock.
This brake equipment utilizes extension spring and the independent air chamber cooperating of carrying out, and can control the execution air chamber by the three-dimensional master cock and whether carry out action, carries out the braking during standstill or the brake off of appointment.When the three-dimensional master cock is positioned at the driving shelves, pressure gas in the air receiver enters to carry out in the air chamber by the execution pipeline and promotes pushrod movement, overcome spring tension and make the swing of bonded assembly fork, draw back extension spring and put aside potential energy, loosen steel rope simultaneously and make the brake control lever return promptly remove braking during standstill, at this moment superimposed trailer can cruising; When three-pointswitch pushed the braking during standstill gear, the pressure gas of carrying out in the air chamber was emitted, and carried out air chamber push rod return, the potential energy of extension spring savings restores to the original state spring, the swing of pulling fork reversing sense, tense wire rope drives the brake control lever rotation simultaneously, produces braking.This device can be reduced to safe air pressure when following at the brake-air line internal gas pressure simultaneously, produces braking thereby spring draws fork automatically and brake control lever is rotated, and reaches to prevent unexpected purpose.
This holding brake device can be checked the gaseous tension of brake propulsion source air receiver in the driving process in good time, in the process of moving, when reducing as the service braking system internal gas pressure, then this device can be braked voluntarily, avoid the superimposed trailer get out of hand, improved the traffic safety performance, behind the trouble-shooting, when air pressure rises to normal working, just can remove the braking of this device.Special holding brake device makes the more excellent performance of this brake system.And have characteristics simple in structure, that brake accuracy is high, safe and reliable.
Description of drawings:
Accompanying drawing is the structural representation of the utility model holding brake device.
The specific embodiment:
With reference to accompanying drawing, this holding brake device relates to brake control lever 22, fork 14 and be connected between the two drawing the fork 17, steel rope pull bar 20, steel rope 12, brake control lever draws fork 13, brake control lever 22 is in vehicle bridge 21 back, brake control lever draws fork 13 to be hinged in the upper end of fork 14, brake control lever draws fork 13 to be connected with an end of steel rope 12, the other end of steel rope 12 is connected on the steel rope pull bar 20, there is support wheel 16 to support in the middle of the steel rope 12, support wheel 16 is arranged on the support wheel support 19 that is fixed on the superimposed trailer longeron 3, steel rope pull bar 20 is connected with drawing fork 17, draw fork 17 to be hinged in the lower end of fork 14, porose in the middle of the fork 14, pass this hole and be provided with bearing pin 4 fork 14 is hinged on support 11, support 11 is fixed on the superimposed trailer center member 1.Hang with extension spring 5 in the upper end of fork 14, extension spring 5 hangs over by spring pull bar 6 and is fixed on superimposed trailer and runs through on the rob support 7 of crossbeam 2, on vehicle body air chamber fixed beam 18, be fixed with and carry out air chamber 8, the push rod of carrying out air chamber 8 is hinged on this end of fork 14, and the gas circuit of carrying out air chamber 8 is communicated with air receiver 10 by carrying out air pipe 15 and three-dimensional master cock 9.
