Embodiment
Such as Fig. 1, 2, 3, 4, shown in 5 and 6, one kind exempts from traction and folds breakdown trailer, including girder 3, folded beam 4, crossbeam 5, take turns support 6 and trailer wheels 7, the head end of girder 3 is provided with the connector 8 being connected for the tow ball with breakdown lorry, the other end of girder and one end of folded beam are hinged by the main beam pivot part and folded beam hinge member being separately fixed on girder and folded beam, the folded beam gas spring 9 for promoting folded beam 4 to deploy is set between girder 3 and folded beam 4, the both sides of folded beam 4 have the crossbeam 5 being hinged with folded beam 4, wheel support 6 has two, two wheel supports 6 are arranged on crossbeam 5, and it is located at the both sides of folded beam 4 respectively.Wheel support 6 is the rectangle frame being made up of sleeve pipe 6-1, support bar 6-2, rear lever 6-3 and connecting rod 6-4, sleeve pipe 6-1 is slippingly enclosed within crossbeam, support bar 6-2 is vertically arranged with sleeve pipe 6-1, lever 6-3 and sleeve pipe 6-1 be arranged in parallel afterwards, support bar 6-2 is fixedly connected with sleeve pipe 6-1, connecting rod 6-4 is fixedly connected with rear lever 6-3, connecting rod 6-4 is hinged with sleeve pipe 6-1, lever 6-3 and support bar 6-2 is by latch pin joint afterwards, and trailer wheels 13 are arranged on by mechanical jack elevating mechanism 23 on the support bar 6-2 of wheel support.
