Abstract
The utility model discloses a hollow axle wheel pair which effectively reduces the integral weight of the axle through reducing the mass of the axle as well as promotes and improves the dynamic performances for the running of a railbound vehicle. Besides, an internal inspection device is used to realize the axle inspection detection on the vehicle under a normal use state. The wheel pair includes the axle and two wheels connected withthe two ends of the axle; the axle is provided with an internal through hole which is transversely penetrated. The interference assembly between the wheels and the axle can be realized through the modes of press mounting, hot mounting or other modes by adopting the hollow axle. The assembled wheel pair is connected with the drive mechanism and the bearing mechanism of the railbound vehicle.
Description
Technical field
The utility model relates to a kind of the wheel forming, and adopts tubular axle to replace existing traditional solid axle particularly, belongs to mechanical manufacturing field.
Background technology
Wheel is the important component part of rail vehicle truck to composition, and existing traditional rail vehicle truck generally adopts solid axle.Because wheel is one to be the chief component of spring with lower member to composition, one is that spring is excessive with the weight of lower member, can directly have influence on the dynamics design and the Performance Match of guideway vehicle, correspondingly increases design and manufacturing cost.
Be to improve and guarantee the safe operation of guideway vehicle, need termly axletree is detected defect detecting test with internal crack.Because existing axletree is a solid construction, therefore can only adopt the external detection means, but also needs and to unload with axletree bonded assembly multiple arrangement, both expended time in too much and manpower, and testing result is also inaccurate.
Summary of the invention
Tubular axle formula wheel described in the utility model is right, and its design goal is to address the above problem and adopts the open core type axletree, reduces the axletree overall weight effectively by the quality that reduces axletree, promotes and improve the dynamic performance of guideway vehicle operation.
Another design goal is, can use inner defect-detecting equipment by the open core type axletree, to realize the axletree defect detecting test of vehicle under normal operating condition, helps to improve detection efficiency and accuracy.
For realizing above-mentioned design goal, described tubular axle formula wheel is to including an axletree and at axletree two ends bonded assembly wheel, its improvements are that axletree has an interior bone that laterally runs through.
Adopt tubular axle, wheel can by press-fit, hot charging or alternate manner realize the interference assembling with axletree.Wheel after the assembling is right, is connected with load carrier with the driving of guideway vehicle.
On axletree, various drivings or brake equipment can be installed in addition, on wheel, also can install and drive or brake component, by material to substitute and optimize be to solve the load problem that the operation of tubular axle vehicle produces.
Do not deflect and asymmetry when taking turns operation for improving, described through hole and axletree have same central axis.
Further prioritization scheme is that described through hole is the cylindrical-shaped structure of a rule.
For tackling outside high temperature and wet environment, the two side ends of through hole respectively capping one cover of dust is arranged.
Change with adaptive temperature and humidity, adopt above-mentioned both sides sealing structure can guarantee that corrosion phenomena does not appear in tubular axle inside.
As mentioned above, the utility model tubular axle formula wheel is that the axletree quality reduces and directly reduced the axletree overall weight, improves the dynamic performance of guideway vehicle operation effectively to the advantage that has.And, can realize the crack-detecting inspection of axletree by adopting inner defect-detecting equipment, detection efficiency and accuracy are higher.
Description of drawings
Fig. 1 is the right generalized section of described tubular axle formula wheel;
Fig. 2 is the enlarged diagram of I bilge construction among Fig. 1;
Have wheel 1, axletree 2, through hole 3, cover of dust 4 as depicted in figs. 1 and 2.
The specific embodiment
Through hole 3 and axletree 2 have same central axis, and through hole 3 is cylindrical-shaped structures of a rule.
The two side ends of through hole 3 respectively capping one cover of dust 4 is arranged.
Right as above-mentioned tubular axle formula wheel, wheel 1 carries out interference with axletree 2 and assembles by mode such as press-fiting, and the wheel after the assembling is to being connected with load carrier with the driving of guideway vehicle.
Content to sum up, present embodiment only is described with regard to the utility model preferred version in conjunction with the accompanying drawings.Can take a hint in view of the above for one of ordinary skill in the art, and direct derivation goes out to meet other alternative structure of above-mentioned design concept, other architectural features that obtain thus also should belong to the protection domain of this patent.
