Detailed description of the invention
Detailed description of the invention:
As shown in Figure 1, 2, 3, fully-trailed carriage brake traction device, comprises pull cylinder 1 and the eye hitch 3 with handle 2, is fixed with brake pump 4 in the middle part of described pull cylinder 1; 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 end is 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; The barrel of handle 2 and pull cylinder 1 offers pin-and-hole and the movable plug-in mounting locating dowel pin 7 in it; Between the spacing round platform 5 in described handle 2 end and brake pump 4, Buffer Unit and reset assembly is disposed with in pull cylinder 1.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 and forms with the slide bar 13 with door 12 in the adjust bar 11 of door 10 and right output port by recoil spring 8, gap; Described adjust bar 11 is spirally connected with described sleeve pipe 9 inner chamber, described slide bar 13 and sleeve pipe 9 inner chamber bearing fit; As shown in Figure 1,3, described reset assembly be fixed on slide bar 13 by interval door 12 on the right side of spring fitting room 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 end is slided and extends described spring fitting room 14 and contacted with the door 12 of slide bar 13 by pressing plate 22, and the slip of push rod 16 right-hand member is extended spring fitting room 14 and is 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 be arranged in pull cylinder 1, and described hydraulic pipe 18 mouth of pipe extended 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, rotate in sleeve pipe 9 for avoiding described slide bar 13, the tube wall that sleeve pipe 9 is relative offers slotted hole 20 vertically respectively, and described slide bar 13 offers pin-and-hole and put bearing pin 21 in the inner, described bearing pin 21 two ends extend in corresponding slotted hole 20 respectively.
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 the pin-and-hole be opened in handle 2 and pull cylinder 1 barrel.When tractor truck is braked, trailer continues near tractor truck under effect of inertia, spacing round platform 5 end face of handle 2 end is made to extrude the door 10 of Buffer Unit adjust bar 11 to the right, and then after compression recoil spring 8 buffering, inertial impact force is reached on the pressing plate 22 of push rod 16 left end, power is transmitted retracing spring 15 by thrust and is promoted the piston 17 of brake pump 4 by push rod 16, hydraulic oil in brake pump 4 is exported to trailer brake wheel cylinder by hydraulic pipe 18 brake, stop when the pressing plate 22 of push rod 16 left end moves to 14 position, spring fitting room; The inertia impulsive force of whole braking procedure is buffered spring 8 and absorbs, and avoids the piston 17 of brake pump 4 and the rigid collision of push rod 16, effectively prevent the severe impact that brake pump 4 is subjected to.The stroke of push rod 16 can be adjusted by the position 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 in the pin-and-hole be opened on handle 2 and pull cylinder 1 barrel, make to lock between handle 2 and pull cylinder 1, now the spacing round platform 5 of handle 2 end is fixed in pull cylinder 1 and can not touch Buffer Unit, reach inertial impact force transmission backward when blocking reversing, realize reversing.
