The invention has the advantages that and carry hydraulic brake system, when tractor truck is braked, rely on inertial impact force can make trailer steadily, safety arrestment, during backing towing vehicle, can cut off again inertial impact force and transmit backward, realize safety reversing smoothly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the I portion structure for amplifying schematic diagram of Fig. 1.
Fig. 3 is the structural representation of Buffer Unit of the present invention.
The specific embodiment:
As shown in Figure 1, 2, 3, fully-trailed carriage brake traction device, comprises pull cylinder 1 and with the eye hitch 3 of handle 2, described pull cylinder 1 middle part is fixed with brake pump 4; The handle 2 of described eye hitch 3 slides and is plugged in pull cylinder 1 left-hand cylinder mouth; As shown in Figure 2, handle 2 ends are provided with spacing round platform 5, and the left tube port position of pull cylinder 1 is provided with limited ring dais 6, and the diameter of described spacing round platform 5 is greater than the internal diameter of described limited ring dais 6; On the barrel of handle 2 and pull cylinder 1, offer pin-and-hole and the movable plug-in mounting locating dowel pin 7 in it; In pull cylinder 1, between the described handle 2 spacing round platforms 5 in end and brake pump 4, be disposed with Buffer Unit and reset assembly.As shown in Figure 3, described Buffer Unit is arranged on sleeve pipe 9 in described recoil spring 8, is plugged in described recoil spring 8 left port with the slide bar 13 with door 12 in the adjust bar 11 of door 10 and right output port and forms by recoil spring 8, gap; Described adjust bar 11 is spirally connected with described sleeve pipe 9 inner chambers, described slide bar 13 and sleeve pipe 9 inner chamber bearing fits; As shown in Figure 1,3, described reset assembly by interval, be fixed on slide bar 13 door 12 right sides spring fitting chamber 14 and put retracing spring 15 in the inner and run through the push rod 16 that described retracing spring 15 arranges and form; Described push rod 16 left ends slide and extend described spring fitting chamber 14 and contact with the door 12 of slide bar 13 by pressing plate 22, and push rod 16 right-hand members slips are extended spring fitting chamber 14 and are connected with the piston 17 of described brake pump 4; The control liquid mouth of described brake pump 4 is connected with the hydraulic pipe 18 in being arranged on pull cylinder 1, and the mouth of pipe that described hydraulic pipe 18 extends outside pull cylinder 1 is provided with for controlling with trailer brake wheel cylinder the adaptor union 19 that liquid mouth is connected.As shown in Figure 3, for avoiding described slide bar 13 in the interior rotation of sleeve pipe 9, on the relative tube wall of sleeve pipe 9, offer respectively vertically slotted hole 20, offer pin-and-hole and put bearing pin 21 in the inner on described slide bar 13, described bearing pin 21 two ends extend to respectively in corresponding slotted hole 20.
Principle of work of the present invention is summarized as follows:
During use, eye hitch 3 is connected with tractor truck towing hook, and locating dowel pin 7 is extracted from be opened in the pin-and-hole handle 2 and pull cylinder 1 barrel.When tractor truck is braked, trailer continues near tractor truck under effect of inertia, make spacing round platform 5 end faces of handle 2 ends push the door 10 of Buffer Unit adjust bar 11 to the right, and then after compression recoil spring 8 bufferings, inertial impact force is reached on the pressing plate 22 of push rod 16 left ends, push rod 16 is subject to thrust that power is transmitted to retracing spring 15 and promotes the piston 17 of brake pump 4, hydraulic oil in brake pump 4 is exported to trailer brake wheel cylinder by hydraulic pipe 18 and brake, when the pressing plate 22 of push rod 16 left ends moves to 14 position, spring fitting chamber, stop; The inertia impulsive force of whole braking procedure is cushioned spring 8 and absorbs, and has avoided the rigid collision of piston 17 with the push rod 16 of brake pump 4, the severe impact of effectively having avoided brake pump 4 to be subjected to.The stroke of push rod 16 can be by the position adjustment that is spirally connected axial between adjust bar 11 and sleeve pipe 9, to adapt to the braking needs under different pressures.
When backing towing vehicle, locating dowel pin 7 is inserted and is opened in the pin-and-hole on handle 2 and pull cylinder 1 barrel, make locking between handle 2 and pull cylinder 1, now the spacing round platform 5 of handle 2 ends is fixing and can not touch Buffer Unit in pull cylinder 1, while reaching blocking-up reversing, inertial impact force transmission backward, realizes reversing.
