Traditional motor vehicle wheels is by core wheel and rim gun iron link, inside wheel is all gun iron links, when there are vibrations in vehicle body, wheel will bear the vibrations of vehicle body, and wheel can not discharge the power producing vibrations, can only be discharged into by the vibrations of vehicle body self the unbalanced power received, bring human discomfort to passenger.Because inside wheel is all gun iron links, in vibrations process, gun iron link relation is more easily destroyed, and cause wheel to connect and loosen, improve insecurity, the period of inspection and repair is short.
Utility model content
In order to solve above-mentioned Problems existing, the utility model discloses a kind of low-floor bogie motor-car elastic wheel, its technical scheme is:
Low-floor bogie motor-car elastic wheel, comprise rim, core wheel, pressure ring and vibration isolation rubber, described core wheel center is provided with axis hole, the described axis hole trailing wheel in the heart heart penetrates, and the rounded through hole of axis hole, described axis hole is for fixedly mounting adapter shaft, described rim is arranged on the outside of core wheel, described vibration isolation rubber is arranged between rim and core wheel, described vibration isolation rubber is opening " V " word shape towards rim, described pressure ring is arranged between vibration isolation rubber and core wheel, described pressure ring is pressed onto the centre of vibration isolation rubber from the side of vibration isolation rubber, the one side that described pressure ring and vibration isolation rubber are fitted is arranged to the inclined-plane with degree of dip such as vibration isolation rubbers.
Seal ring is provided with between described pressure ring and core wheel.
Described vibration isolation rubber is by circumferencial direction end to end form of some pieces of rubber blocks along core wheel.
The circumferencial direction of described pressure ring is provided with several screws connecting briquetting and core wheel.
Also comprise connection wire, one end of described connection wire is connected and fixed by bolt and pressure ring, and the other end is connected and fixed by bolt and rim, and described connection wire is in " U " oxbow.
Principle of work of the present utility model is:
Rim of the present utility model is used for the rail contact with railroad vehicle, when the utility model re-uses, first two this low-floor bogie motor-car elastic wheels are connected with an adapter shaft, adapter shaft and core wheel are fixed, two this low-floor bogie track widths of the distance between motor-car elastic wheel and railroad vehicle coincide, two rims lay respectively in corresponding rail groove, the motor-car elastic wheel circumference rolling in orbit of this low-floor bogie, motor-car is pulled to advance, weight from car body is pressed on this low-floor bogie motor-car elastic wheel, produce at vehicle body and to rock or when discontinuity, traditional low-floor bogie motor vehicle wheels and track rigid contact, and inside wheel is all rigidly connected, inside wheel can not discharge or alleviate any power, cause power will be discharged by rocking of vehicle body, and the utility model, vibration isolation rubber in wheel is when stressed, certain elastic deformation can be there is in self, release force, reduce rocking of vehicle body, inside wheel is made to have certain plastic deformation space, there is release force, reduce the effect that vehicle body rocks.
The beneficial effects of the utility model:
The utility model has set up vibration isolation rubber between core wheel and rim, is out of shape by the natural resiliency of vibration isolation rubber, can release portion from the power of vehicle body, the power that release portion branch causes vehicle body to rock or vibrates, reaches the effect of vibration damping.
Firmly be fixedly mounted in wheel by witness rubber by briquetting, the shape of vibration isolation rubber is conducive to when shape distortion does not occur wheel, and vibration isolation rubber produces certain elastic deformation, and release portion is from the power of the instability of vehicle body.
