The specific embodiment
Below in conjunction with the accompanying drawing and the detailed example explanation of the enforcement specific embodiment of the present utility model.
As shown in Figure 1, a kind of trailer braking protection valve power distribution device, main by the box body 3 that has cover plate 10, braking during standstill pull bar 1, service brake pull bar 2, braking bindiny mechanism 5, the right braking in back stay cord 8 and a left side, back braking stay cord 9 constitute, described box body Inner Front End is equipped with service brake pull bar and braking during standstill pull bar, service brake pull bar and braking during standstill pull bar one end respectively with braking bindiny mechanism bolted connection, braking bindiny mechanism is connected with the left stay cord of braking of back right braking stay cord and back, is fixed with slide rail 4 on the described box body madial wall, described braking bindiny mechanism left side and right side respectively are equipped with two rollers 13, and roller rolls with slide rail and is connected.Described service brake pull bar and braking during standstill pull bar one end are respectively equipped with and brake the bolted fork pin 14 of bindiny mechanism, described braking bindiny mechanism comprises sliding shoe 5-1, connecting panel 5-2, adapter plate 5-3 and spring contiguous block 5-4, described sliding shoe and connecting panel are affixed, described connecting panel is provided with parallel each other elongated slot 5-5, and the fork pin on service brake pull bar and the braking during standstill pull bar is connected by the elongated slot of bolt with the connecting panel of braking bindiny mechanism.In the braking bindiny mechanism 5, sliding shoe 5-1 is used for installing roller 13, connecting panel 5-2 is used for connecting service brake pull bar 2 and braking during standstill pull bar 1, and adapter plate 5-3 is used for connecting the right braking in back stay cord 8 and a left side, back braking stay cord 9, and spring contiguous block 5-4 is used for connecting pull back spring 7.These four parts are fixed by welding in together, form braking bindiny mechanism 5.More frequent than emergency brake system frequency of utilization because of service braking system, the use dynamics is more violent, the service brake pull bar is arranged on the midway location of brakig force distribution device, to reduce the shearing force that moment of torsion is produced.Sliding shoe is not held and is fixed with adapter plate, and adapter plate is provided with two through hole (not shown), connects back right braking stay cord and a left side, back braking stay cord by screw bolt and nut 6; Be provided with the spring contiguous block at the adapter plate midway location, between the Connection Block 3-7 on spring contiguous block and the box body 3 pull back spring 7 be installed, the reach of glancing impact braking bindiny mechanism, Compression and Expansion spring.Behind the brake off, the pull back spring that is stretched resets, and impels braking bindiny mechanism return.Left side and right side in braking bindiny mechanism respectively are equipped with two rollers 13, roller is fixed on the centre of sliding shoe 5-1 by bearing pin 12, roller is middle recessed inward arc pulley, with 4 contact matching of slide rail fixing on the box body, roller is the tin bronze material, the slide rail of both sides is a steel matter in the box body, the two some contact matching has self-lubricating function, make braking bindiny mechanism be stuck in box body inside simultaneously, can not double swerve, right braking stay cord is braked the stay cord forward pitch from identical with a left side, back after making, thereby makes left and right sides braking force unanimity.Friction drag is little, moves forward and backward unobstructed.Form by box body 3 and cover plate 10.Have 6 circular hole 3-9 on the described box plate 3-3, be used for by the bolted connection trailer, have tapped bore 3-10 on gusset 3-1 and the stay bearing plate 3-4, be used for connecting cover plate 10 by screw, respectively have two round taper hole (not shown) on left side board 3-6 and the right side board 3-5, be used for slide rail 4 is fixed on box body.Have two circular groove (not shown) on the header board 3-2, be used for fixing service brake pull bar 2 and braking during standstill pull bar 1, have two hole (not shown) on the back plate 3-8, be used to install back right braking stay cord and a left side, back braking stay cord.Box body is connected by screw 11 with cover plate.Be provided with the packing seal (not shown) between described cover plate and the box body, and be tightly connected by screw.Braking bindiny mechanism is stuck in the box body, can not double swerve, and the forward pitch that stay cord is braked on a back right braking stay cord and a left side, back is from being identical, therefore, left and right sides braking force is identical, makes left and right sides tire braking force unanimity, has solved the problem of glancing impact trailer sideslip.
The occupation mode of this trailer braking protection valve power distribution device is divided into two kinds of situations: service brake and braking during standstill.
1, service brake
When tractor truck to overtake the time, drive trailer and travel.The tractor truck braking, traction head on the trailer will drive the reach of service brake pull bar by a series of mechanisms, the service brake pull bar is by fork pin and bolted connection braking bindiny mechanism, the both sides of braking bindiny mechanism are equipped with roller by bearing pin, four rolling can be in slideway scroll forward and backward, roller drives the reach of braking bindiny mechanism, this moment is because the connecting panel of braking bindiny mechanism has sufficiently long elongated slot, and fork pin also has sufficiently long elongated slot on the braking during standstill pull bar, braking bindiny mechanism is along with the reach of service brake pull bar, move forward making in the elongated slot of connecting panel fork pin in the braking during standstill pull bar, do not influence the braking during standstill pull bar, therefore, the braking during standstill pull bar is motionless.Braking bindiny mechanism drives the reach of back braking stay cord, with the drg braking, reaches the purpose of parking.The back pull back spring that stops will be braked bindiny mechanism and retract initial position.
2, braking during standstill
When the trailer stagnation of movement, need add braking during standstill, to drive the reach of braking during standstill pull bar by brake-applying handle, the braking during standstill pull bar is connected braking bindiny mechanism by fork pin with bearing pin, drive the reach of braking bindiny mechanism, this moment is because the connecting panel of braking bindiny mechanism has sufficiently long elongated slot, and fork pin also has sufficiently long elongated slot on the service brake pull bar, braking bindiny mechanism is along with the reach of braking during standstill pull bar, to connecting panel be moved forward in the driving lever connection in the elongated slot of fork pin, do not influence the service brake pull bar, therefore, the service brake pull bar is motionless.Braking bindiny mechanism drives the reach of back braking stay cord, with the drg braking, reaches the purpose of Parking.Pull back spring will be braked bindiny mechanism and retract initial position behind the cancellation braking during standstill.
By above two kinds of situations as can be known, this trailer braking protection valve power distribution device is unified emergency brake system separately with service brake, makes it the phase mutually noninterfere, has improved braking effect.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
