Detailed description of the invention
By particular specific embodiment, embodiment of the present utility model is described below, person skilled in the art scholar the content disclosed by this specification sheets can understand other advantages of the present utility model and effect easily.
As shown in Figure 1, the utility model provides a kind of Platform for tricycle carrying structure, and comprise two longerons 1 in left and right, the afterbody of every root longeron is all provided with vehicle frame rear 2, and vehicle frame rear 2 is removably connected on longeron 1.Longeron 1 of the present utility model is made up of two parts, the length of whole chassis side rail can be regulated by the length of adjustment vehicle frame rear, thus meet the installation requirement in multiple different size compartment, for three-wheel vehicle production firm, so just do not need the longeron manufacturing multiple different length, reduce manufacturing cost.
Vehicle frame rear 2 of the present utility model is removably connected to the afterbody of chassis side rail 1, detouchable connection mode is varied, such as a terminal pad can be set at the afterbody of longeron 1, another terminal pad is set in the front end of vehicle frame rear 2, is coupled together by screw bolt and nut between two terminal pads.
As shown in Figure 2, the present embodiment is provided with the first connection journal stirrup 3 at the afterbody of longeron 1, is provided with the second connection journal stirrup 4 in the front end of vehicle frame rear 2, and described first connection journal stirrup 3 and described second is connected journal stirrup 4 and is cross-linked.Preferably, the structure that described first connection journal stirrup 3 and described second connects journal stirrup 4 is identical, and all comprise block 5, contiguous block 7 and grafting block 6, described contiguous block 7 and described grafting block 6 are distributed in the both sides of described block 5; Described longeron 1 is rectangular tube with described vehicle frame rear 2, and the described first grafting block 6 connecting journal stirrup 3 is plugged on the afterbody of described longeron 1, and the described second grafting block 6 connecting journal stirrup 4 is plugged on the front end of described vehicle frame rear 2; Described first connects journal stirrup 3 is overlapping with the described second contiguous block 7 being connected journal stirrup 4, and described first connects on contiguous block 7 that journal stirrup 3 and described second connects journal stirrup 4 and have mutual corresponding connecting bore 8, coupled together by screw bolt and nut between described first connection journal stirrup 3 is connected journal stirrup 4 contiguous block 7 with described second.Connection journal stirrup of the present utility model comprises block, contiguous block and grafting block, during assembling, first one of them grafting block connecting journal stirrup is plugged into longeron afterbody, another grafting block connecting journal stirrup is plugged into the front end of vehicle frame rear, and then the contiguous block that two connect journal stirrup is overlapping, finally again the contiguous block that two connect journal stirrups is coupled together by screw bolt and nut, assemble very convenient.
