Abstract
The utility model relates to a drawbar hook reinforcement structure. The utility model mainly solves the condition that tension fracture deformation can exist in general drawbar hooks in the drawing process. The drawbar hook reinforcement structure comprises a longitudinal girder, a drawbar hook arranged on the longitudinal girder and reinforcement plates. One part of the reinforcement plate is connected with the drawbar hook, the other part is connected with the longitudinal girder, a plurality of installation holes are arranged in the reinforcement plates, and bolts are arranged in the installation holes so as to fix the drawbar hook with the longitudinal girder. In the utility model, by connecting the reinforcement plates to the drawbar hook and the longitudinal girder, the reinforcement plates, the drawbar hook and the longitudinal girder form an overall reinforcement structure. The drawbar hook adopts a multiple point fixing mode, thereby avoiding the problem of insufficient strength of connecting position of the drawbar hook and the longitudinal girder. The reinforcement plates have simple structure, convenient production and convenient installation.
Description
Technical field
The utility model relates to a kind of vehicle traction device, relates in particular to a kind of towing hook that makes and connects more firm towing hook additional strengthening.
Background technology
Towing hook is important automobile structure, pull in the process at vehicle, towing hook and towing hook dependency structure will bear big pulling force, and towing hook intensity will be used car load and produce considerable influence, therefore just should guarantee that in the styling design development phase towing hook and relevant main stressed member possess enough intensity.General towing hook is fixed on automobile front side member or the floor side member by bolt, perhaps is provided with screw thread in the towing hook rear end, and towing hook is threaded on automobile front side member or the floor side member.When adopting the former mode, generally all just adopt bolt that the bottom of towing hook and longeron are just fixed and finished, but this structure pulls phenomenons such as also there being drawing crack in the process at automobile, and the towing hook residual deformation is excessive, does not satisfy operating needs.China's utility model patent 200820072815.0 discloses a kind of automobile front tow hook device, this trip mechanism is made up of front tow hook, latch, front tow hook becomes convex shape, be provided with some mounting holes in the front tow hook rear end, by being bolted on the longeron, but its Joint strenght is big not enough, in use still exists by the phenomenon of drawing crack.
Summary of the invention
The utility model has mainly solved the drawing crack distortion can appear in general towing hook in pulling process situation, provides a kind of towing hook holding capacity that makes bigger, the more difficult towing hook additional strengthening that is out of shape by drawing crack.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of towing hook additional strengthening, comprise longeron and the towing hook that is installed on the longeron, also comprise a brace panel, a described brace panel part is connected on the towing hook, another part is connected on the longeron, on brace panel, be provided with several mounting holes, in mounting hole, be provided with bolt brace panel and towing hook, longeron are fixed.Brace panel and towing hook, longeron adopt bolt to fix, and have constituted a single-piece additional strengthening, thereby have avoided the problem of towing hook and longeron connection location undercapacity.Brace panel is simple in structure, is convenient to produce, and only needs when mounted brace panel and longeron and towing hook employing bolt are got final product.
As a kind of preferred version of such scheme, described brace panel comprises connecting portion one that links to each other with towing hook and the connecting portion two that links to each other with longeron, the step structure that interlaces by continuous formation one height of interconnecting gangway between described connecting portion one and the connecting portion two.The shape of brace panel and towing hook, longeron surface configuration fit, and make it to be connected close and firm more with brace panel with towing hook, longeron.
As a kind of preferred version of such scheme, on connecting portion one and connecting portion two, be respectively equipped with a mounting hole, be provided with bolt in the mounting hole connecting portion one, connecting portion two are fixed with longeron, towing hook respectively.Be respectively equipped with on longeron, the towing hook with connecting portion two on the corresponding through hole of mounting hole, this through hole and the corresponding coincidence of mounting hole on the connecting portion two, after bolt passes connecting portion two, towing hook, longeron, be tightened with nut, also be provided with on the longeron with connecting portion one on the corresponding through hole of mounting hole, this through hole and the corresponding coincidence of through hole on the connecting portion one, bolt is tightened with nut after passing connecting portion one, longeron.
A kind of preferred version as such scheme is provided with some reinforced ribs on brace panel, described reinforced rib is extended on the connecting portion two once interconnecting gangway by connecting portion.Strengthened the intensity of brace panel, made that the reinforcement version is not yielding, in pulling process, be difficult for by drawing crack more.
As a kind of preferred version of such scheme, outward flanging is formed with connecting portion three on connecting portion 21 sides, and described connecting portion and unhook fit, and connecting portion three shapes are corresponding with the towing hook surface configuration.This connecting portion three can be so that towing hook be difficult for being out of shape by drawing crack in pulling process.
The utility model has the advantages that:, make brace panel, towing hook and longeron constitute a single-piece additional strengthening by being connected brace panel with longeron at towing hook.Towing hook is adopted the multiple spot fixed form, thereby avoided the problem of towing hook and longeron connection location undercapacity.This brace panel is simple in structure, is convenient to produce, and is easy for installation.
