Abstract
The utility model provides a clamping spring special for a propelling rod. The clamping spring is formed by an elastic metal body, wherein the elastic metal body is composed of a column-shaped spring formed by winding and rolling one metal piece for a plurality of circles. The edge of the outer side of the surface of the metal piece of the column-shaped spring is higher than the edge of the inner side, namely, an inclined face is formed on the surface of the metal piece, and the inclination angle ranges from three degrees to five degrees. The clamping spring is reasonable in structural design, firm in fixing and durable, and effectively ensures that a rubber core installed in the propelling rod has good elastic deformation effect, and the rubber core is prevented from getting loose and coming out from the interior of the propelling rod in the pushing, pulling, swinging and stressing processes; meanwhile, the inclination face with the angle ranging from three degrees to five degrees, and a part of the action force is effectively eliminated, so that a vehicle runs stably.
Description
Technical field
The utility model belongs to auto parts machinery technical field, and what be specifically related to is a kind of special jump ring being used in conjunction with track bar and glue core.
Background technique
The track bar Main Function using in automobile axle is for leading and effect of power transmission, because automobile bears in the process of moving larger push-pull effort and rocks power, the inner stressed generation elastic strain of torque rod bushing of installing in its push rod two ends, to reduce the interference of vibrations and external force, play buffer function, thereby Vehicle Driving Cycle is tended to be steady all the time, therefore, must guarantee that the glue core that is arranged on track bar inside has very strong elastic strain effect, so that in push-and-pull with rock when stressed, glue core can not loose from track bar inside, in order to solve this phenomenon, make glue core in track bar, bring into play elastic strain effect and be not easy looses in track bar, people develop the various devices for fixing glue core, comprising open type jump ring as shown in Figure 1, there is following shortcoming in fixing glue core process in this open type jump ring: in the time that track bar is subject to push-pull effort or rocks power, the glue core that must need to be arranged on track bar inside balances out this active force by elastic strain, guarantee Vehicle Driving Cycle is steady, and when individual layer jump ring fixing glue core, along with the active force acting on track bar increases, very easily jump ring collapsed de-or break, make glue core from loose glue in track bar out, cannot reach elastically-deformable buffer function.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and a kind of novel structure is provided, and fixed and effective augmented thrust bar internal sizes core carries out special jump ring in elastically-deformable track bar.
The utility model is achieved through the following technical solutions: special jump ring in a kind of track bar, to be formed by a metal elastic gonosome, the cylindrical spring that this metal elastic gonosome is wound around curling some circles by a strip metal sheet forms, and on the tinsel surface of cylindrical spring, the outer ledge of its tinsel is higher than inside edge, be that tinsel surface forms a plane of inclination, its angle of inclination is 3-5 degree.
On the tinsel edge end face of two free terminals of described metal elastic gonosome, be equipped with slot.
Described slot is U-shaped breach.
The cylindrical spring that described metal elastic gonosome is at least wound around curling two circles by a strip metal sheet forms.
The width of described tinsel is 0.5-3CM.
Preferably, described tinsel adopts high-quality spring steel material composition.
The beneficial effects of the utility model embody and are: compared with prior art, the utility model reasonable in design, fixed durable again, effectively eliminate partial action power by the plane of inclination that 3-5 degree is set simultaneously, effectively guarantee that the glue core that is arranged on track bar inside has very strong elastic strain effect, so that in push-and-pull with rock when stressed, glue core can not loose from track bar inside, makes in Vehicle Driving Cycle process more steady.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in detail.
Fig. 1 is prior art clip spring structure schematic diagram.
Fig. 2 is the utility model structural representation.
Fig. 3 is schematic diagram before the utility model jump ring compresses in assembly structure.
Fig. 4 is the utility model jump ring confined state schematic diagram in assembly structure.
Following is the concrete title of each mark in figure: 1 metal elastic gonosome, 101 free terminals, 102 slots, 103 free terminals, 104 inside edges, 105 outer ledges, 106 plane of inclination, 2 glue cores, 3 distance rod heads.
Embodiment
As shown in Figure 2, special jump ring in a kind of track bar, the metal elastic gonosome 1 being formed by a rigid material, this metal elastic gonosome 1 is the cylindrical spring composition that is wound around curling some circles by a rigid metal sheet, in order better to bring into play this elastomeric effect, on the tinsel surface of cylindrical spring, be set to outer ledge 105 higher than inside edge 104, be that tinsel surface forms an intilted plane of inclination 106, its angle of inclination is 3-5 degree, the setting of this plane of inclination 106 is in order better to eliminate the active force acting on track bar, and active force is larger, the jump-ring slot of jump ring and distance rod head 3 inwalls pastes tightlyer.
On the tinsel edge end face of two free terminals (101,103) of described metal elastic gonosome 1, be equipped with slot 102.
Described slot 102 is U-shaped breach.
As shown in Figure 3, the utility model jump ring is that glue core 2 is fixed in distance rod head 3, prevent that glue core 2 from getting loose in distance rod head 3 under.
As showing of Fig. 4, in the time that distance rod head 3 is subject to push-pull effort or rocks power, the glue core 1 of distance rod head 3 inside is stressed, and fit completely with distance rod head 3 inwalls in jump ring surface, instantaneous this active force is fallen by the plane of inclination partial offset on jump ring 3, thereby effectively guaranteed that vehicle travels steadily all the time.
The above is preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
