Detailed description of the invention
As shown in Fig. 1,2,3,4 and 5, a kind of folding breakdown trailer of brake device, comprises girder3, folded beam 4, crossbeam 5, wheel holder 6 and trailer wheels 7, the head end of girder 3 be provided with for breakdown lorryTow ball connect connector 8, the other end of girder and one end of folded beam by be separately fixed at girder withGirder hinge member and folded beam hinge member on folded beam are hinged, between girder 3 and folded beam 4, arrangePromote the folded beam air spring 9 that folded beam 4 launches, the both sides of folded beam 4 have the horizontal stroke hinged with folded beam 4Beam 5, wheel holder 6 has two, and two wheel holders 6 are arranged on crossbeam 5, and lay respectively at the both sides of folded beam 4,Trailer wheels 7 is arranged in wheel holder 6.
Girder 3 is two-part Collapsible structure, between two telescopic sections, buffer spring is set.
In trailer wheels 7, brake is installed, brake operation mechanism is installed on girder 3, brake operation machineStructure comprises brake shifting block 24-1 and push rod 24-2, and brake shifting block 24-1 is arranged on the back segment of girder by rotating shaftUpper, push rod 24-2 is fixed on the leading portion of girder, passes through brake cable between brake shifting block 24-1 and brake24-3 connects, and push rod 24-2 drives and checks trailer wheels 7 by stirring the mode of brake shifting block 24-1.
The crossbeam air spring 19 with gauge tap that drives crossbeam 5 to open, crossbeam gas are installed on folded beam 4The telescopic end of spring 19 is connected with crossbeam 5 by folding connecting rod 14, and the gauge tap of crossbeam air spring 19 is logicalCrossing cam 20 controls that are fixed on girder hinge member opens opportunity. Folded beam air spring can be also band controlThe air spring of switch processed, girder can keep folded state by folded beam air spring after folding. BossWhen shape guarantee crossbeam is completely folding, the gauge tap of crossbeam air spring 19 is in release conditions, and crossbeam can lead toCross crossbeam air spring 19 and keep folded state.
Wheel holder 6 is arranged on crossbeam 5 slippingly, has to folded beam 4 both sides and stretch out on folded beam 4Connecting rod rack 17, between wheel holder 6 and connecting rod rack 17 by the wheel of driven wheel holder 6 slippage on crossbeam 5Holder connecting rod 18 connects, and one end of wheel holder connecting rod 18 is hinged with wheel holder 6, the other end and the company of wheel holder connecting rod 18Shaft bar 17 is hinged.
Dispose procedure is as follows:
Folded beam 4 is slowly opened under the effect of folded beam air spring 9; Open to certain journey at folded beam 4While spending, the cam 20 on girder hinge member is pressed the gauge tap of sill air spring 19, makes crossbeam gas bulletSpring 19 is worked, and opens crossbeam 5, and connector 8 is directly buckled on tow ball, in wheel holder 6, sets up springboard,Accident, fault vehicle, by the upper wheel holder 6 of capstan winch 2 traction, complete whole trailer loading process.
The process of folding trailer unit is as follows:
Manually fold crossbeam, and overcome the folding folded beam 4 of active force and the girder 3 of folded beam air spring 9,Folded beam 4 and girder 3, crossbeam fold while putting in place completely, and the gauge tap of crossbeam air spring 19 is in dischargingState, makes the 19 not flexibles of crossbeam air spring, and the folded state between folded beam 4 and girder 3 can pass throughThe folded beam air spring of employing with gauge tap keeps, and also can keep by modes such as snap close, rope bindingsTheir folded state.
