Abstract
The utility model provides a front spring stabilization concentric shaft of a mine truck. The front spring stabilization concentric shaft comprises a cylinder-shaped shaft body, and two prismatic table body shaft heads which are symmetrically and fixedly connected with the two ends of the shaft body, wherein the diameter of the shaft body is smaller than the lengths of the small sides of the inner end surfaces of the shaft heads. The front spring stabilization concentric shaft has the advantages of being simple in structure, reliable and practical, and solves the problem that a front suspension of the existing mine truck and the whole truck are poor in side inclination resistance.
Description
Technical field
The utility model relates to mechanical parts technical field, is specifically related to the front spring of a kind of mine car and stablizes concentric shafts.
Background technique
In industry, axle is a kind of common connection set, and axle also turns round to transmit the mechanical parts of motion, moment of torsion or moment of flexure therewith as support rotating part, is generally round metal shaft-like, and each section can have different diameters.In practical application, number axis all can be located or limit structure mostly, and these axle construction are more complicated, and difficulty of processing is larger.Especially for existing expanded letter mine car, because this car front suspension is stressed larger, vehicle frame and leaf spring, because of the stressed excessive distortion that produces, cause the anti-inclination of car load poor.At present, this problem is badly in need of being resolved.
Model utility content
The purpose of this utility model is to overcome existing mine car front suspension and the poor problem of the anti-inclination of car load.
For this reason, before the utility model provides a kind of mine car, spring is stablized concentric shafts, comprises that cylindric axle body, symmetry are fixedly connected on the prismoid spindle nose at described axle body two ends, and the diameter of axle body is less than the length of side on the little limit of spindle nose interior edge face.
Wherein, spindle nose is preferably truncated rectangular pyramids body.
Wherein, in spindle nose, be provided with the through hole matching with axle body.
Wherein, the Placement of axle body and spindle nose is welding.
Wherein, spindle nose exterior edge face is provided with mounting hole and multiple tracks stiffening rib.
Wherein, stiffening rib is connected to axle body external part periphery.
Wherein, spindle nose is cast steel spindle nose.
Wherein, axle body is seamless steel pipe axle body.
Before the mine car that the utility model provides, spring is stablized concentric shafts, has advantages of simple in structure, reliable and practical.
Below with reference to accompanying drawing, the utility model is described in further details.
Accompanying drawing explanation
Fig. 1 is the structural representation that before the utility model mine car, spring is stablized concentric shafts;
Fig. 2 is the partial sectional view that before mine car shown in Fig. 1, spring is stablized concentric shafts;
Fig. 3 is the side view that before mine car shown in Fig. 1, spring is stablized concentric shafts.
1. axle body, 2. spindle nose, 3. interior edge face, 4. exterior edge face, 5. mounting hole, 6. stiffening rib.
Embodiment
In order to overcome existing mine car front suspension and the poor problem of the anti-inclination of car load.Before the present embodiment provides the mine car shown in a kind of Fig. 1, spring is stablized concentric shafts.
Shown in Fig. 1, Fig. 2, Fig. 3, before this mine car, spring is stablized concentric shafts, comprises that cylindric axle body 1, symmetry are fixedly connected on the prismoid spindle nose 2 at described axle body 1 two ends, and the diameter of axle body 1 is less than the length of side on spindle nose 2 interior edge face 3 little limits; Spindle nose 2 is preferably truncated rectangular pyramids body; In spindle nose 2, be provided with the through hole matching with axle body 1; Axle body 1 is welding with the Placement of spindle nose 2; Spindle nose 2 exterior edge faces 4 are provided with mounting hole 5 and multiple tracks stiffening rib 6, and it is peripheral that stiffening rib 6 is connected to axle body 1 external part; Spindle nose 2 is cast steel spindle nose; Axle body 1 is seamless steel pipe axle body.
The utility model is applicable to expanded letter mine car, and expanded letter mine car front suspension is stressed larger, for preventing that vehicle frame and leaf spring are because of the stressed excessive distortion that produces, on rear spring back poppet, increases and stablizes concentric shafts, can effectively prevent from rolling.Adopt and stablize after concentric shafts, can effectively improve front suspension and the anti-inclination of car load.Structure of the present utility model is that two ends adopt Cast Steel, and intermediate portion adopts the seamless steel pipe of large wall thickness to be welded, and structure is practical, reliable.
More than exemplifying is only to illustrate of the present utility model, does not form the restriction to protection domain of the present utility model, within the every and same or analogous design of the utility model all belongs to protection scope of the present invention.
