Abstract
The utility model discloses a new -type subway train wheel relates to urban rail transit equipment field, and the center of this new -type subway train wheel's wheel body is equipped with the round recess, and the bilateral symmetry of wheel body is equipped with the spherical lug of two outside bellied hemispherical, and the center department symmetry of the spherical lug of wheel body and both sides is equipped with four measure -alike bolt hole. Accessible fixing bolt and nut pass bolt hole and fix this train wheels in the both sides of train shaft, and the recess of wheel body can block on the train track, prevent effectively that the train is derailed, and wheel body both sides are equipped with the spherical lug of outside bellied hemispherical, can effectively improve the fatigue resistance ability of wheel, can make the vehicle condition that many bends mechanical properties is complicated of wheel adaptation city rail, have improved the life of wheel.
Description
Technical field
The utility model relates to urban rail transit equipment field, particularly the new-type subway train wheel of one.
Background technology
Whether subway train and light rail train are current topmost urban track traffic instruments, and whether the manufacture of train wheel is directly connected to train and can steadily, quickly and safely runs, the parts in joint.Existing subway train wheel follows traditional train wheel moulding mostly, and load-carrying capacity is general.Subway train travels the distance of bend far above Conventional trains, and common train wheel cannot adapt to the traveling under this loading in composite of warp rail, serious curtailment service life of wheel.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of new-type subway train wheel, at wheel body central, place arranges groove, clamp the track of subway, the spherical protrusions of outwardly convex is set in wheel body both sides, increase wheel opposing and travel complicated applied force when bend, extend wheel service life.
For achieving the above object, the utility model provides following technical scheme: a kind of new-type subway train wheel, it is characterized in that: described new-type subway train wheel comprises disc shaped wheel body, the center of wheel body is provided with a circle groove, the bilateral symmetry of wheel body is provided with the hemispheric spherical protrusions of two outwardly convexs, the spherical protrusions of wheel body and both sides is one-piece construction, the center of the spherical protrusions of wheel body and both sides is arranged with four measure-alike bolt through-holes, and bolt through-hole is cylindrical hole.
Preferably, described wheel body and spherical protrusions manufacture by alloy high-carbon steel.
Preferably, the width of described groove 4-6cm less of the width of wheel body.
Preferably, described four bolt through-holes are all vertical with wheel body.
The beneficial effect of above technical scheme is adopted to be: the center of the wheel body of this new-type subway train wheel is provided with a circle groove, the bilateral symmetry of wheel body is provided with the hemispheric spherical protrusions of two outwardly convexs, and the center of the spherical protrusions of wheel body and both sides is arranged with four measure-alike bolt through-holes.Through bolt through-hole, this train wheel is fixed on the both sides of train wheel shaft by bolt of rear end plate and nut, the groove of wheel body may be stuck on train rail, effectively prevent train derailment, wheel body both sides are provided with the hemispheric spherical protrusions of outwardly convex, effectively can improve the anti-fatigue performance of wheel, wheel can be made to adapt to the vehicle condition of many bends mechanical property complexity of city rail, improve the service life of wheel.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
Fig. 1 is the front view of a kind of new-type subway train wheel of the utility model;
Fig. 2 is the left view of a kind of new-type subway train wheel of the utility model.
Wherein, 1-wheel body, 2-groove, 3-spherical protrusions, 4-bolt through-hole.
Detailed description of the invention
The preferred implementation of a kind of new-type subway train wheel of the utility model is described in detail below in conjunction with accompanying drawing.
Fig. 1 and Fig. 2 shows the detailed description of the invention of a kind of new-type subway train wheel of the utility model: this new-type subway train wheel comprises disc shaped wheel body 1, the center of wheel body 1 is provided with a circle groove 2, the bilateral symmetry of wheel body 1 is provided with the hemispheric spherical protrusions 3 of two outwardly convexs, the spherical protrusions 3 of wheel body 1 and both sides is one-piece construction, the center of the spherical protrusions 3 of wheel body 1 and both sides is arranged with four measure-alike bolt through-holes 4, and bolt through-hole 4 is cylindrical hole.
Composition graphs 1 and Fig. 2, wheel body 1 and spherical protrusions 3 manufacture by alloy high-carbon steel, and mechanical property is good, can improve the resistance to abrasion of wheel.The width 4-6cm less of the width of wheel body 1 of groove 2, has ensured that wheel body 1 has enough thickness and hardness in rail both sides, makes wheel not yielding when turning.Four bolt through-holes 4 are all vertical with wheel body 1, and wheel is fixed on the both sides of train wheel shaft by screw bolt and nut, and Assembly &Disassembly is all convenient, are easy to maintenance and replacement part, and wheel can firmly be fixed on wheel shaft by four symmetrical screw bolt and nut.
During installation, first through bolt through-hole 4, this train wheel is fixed on the both sides of train wheel shaft by bolt of rear end plate and nut, the groove 2 of wheel body 1 may be stuck on train rail, effectively prevent train derailment, wheel body 1 both sides are provided with the hemispheric spherical protrusions 3 of outwardly convex, effectively can improve the anti-fatigue performance of wheel, wheel can be made to adapt to the vehicle condition of many bends mechanical property complexity of city rail, improve the service life of wheel.
Above is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
