Abstract
The invention discloses a composite structural wheel of denoise rail vehicle, which comprises the following parts: rim, spoke and shaft sleeve, wherein two ends of spoke connect rim and shaft sleeve; a coil of vibration damping layer is covered on the spoke along length direction, which is made of reinforced plastic of fiber.
Description
Technical field
The present invention relates to a kind of wheel, particularly relate to a kind of composite construction wheel that is used for rail traffic vehicles.
Background technology
Rail traffic vehicles such as train, subway, light rail etc. are in operational process, and wheel high speed scroll in orbit produces vibration and noise, the common integral type rigid wheel that adopts, and noise and vibration is propagated by the steel wheel spoke, and passenger and ambient environment are polluted.The assembled vehicle wheel of vibration has appearred alleviating in the prior art, application number is that 96107574.0 Chinese invention patent application discloses a kind of assembled vehicle wheel, it is that core wheel two parts by the rim of outer ring and inner ring combine, one circle elastic damping spare is set between rim and core wheel, can reaches certain effectiveness in vibration suppression.Yet because wheel is in operational process, spoke is a main media of propagating wheel-rail noise, and existing wheel does not have good solution to the noise control of spoke.
Summary of the invention
A kind ofly can control spoke effectively effect reaches the guideway vehicle wheel of noise reduction effect to propagation of noise thereby the technical problem to be solved in the present invention provides.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: a kind of composite construction wheel of noise reduction rail vehicle, comprising wheel rim, spoke and axle sleeve, captives joint with wheel rim, axle sleeve respectively in the two ends of spoke, wraps up a circle vibration damping layer on the spoke along its length.
Vibration damping layer on the spoke can reduce the vibration and the propagation of noise of spoke effectively, therefore can reduce the noise of wheel significantly.
In order to realize being connected of spoke and wheel rim, axle sleeve, be provided with groove at the inner edge of wheel rim, the end of spoke is inserted in the groove and by the wheel rim left side bead stopper, the right bead stopper of wheel rim that are fixed on the wheel rim and is clamped; The root end face of spoke is an arc-shaped concave, directly cooperates with the periphery of axle sleeve; One side of axle sleeve is provided with annular boss, and opposite side is fixed with the wheel shaft bead stopper, and above-mentioned annular boss and wheel shaft bead stopper clamp the root of spoke vertically; Also be provided with the axle sleeve briquetting between per two spokes, the axle sleeve briquetting is fixed on the periphery of axle sleeve, and in a circumferential direction the root of spoke is clamped.By three bead stoppers and axle sleeve briquetting spoke is fixed on the wheel reliably, has guaranteed wheel integral intensity and rigidity requirement simultaneously.
A kind of preferred version as technique scheme, described spoke two pluckings centres thin and at both ends formation internal shoulder and outer convex shoulder, described vibration damping layer is wrapped in the elongated position between internal shoulder and the outer convex shoulder, the wheel rim at spoke and two ends, axle sleeve form interference fit, this interference fit, form prestressed structure, both improved the force-bearing situation of wheel, strengthened the effectiveness in vibration suppression of wheel again.
Preferably, above-mentioned vibration damping layer is made of fiber-reinforced plastic.
As the further improvement of above-mentioned preferred version, the middle part of spoke is one section thinner pipe link, fills low density foam material between pipe link and the vibration damping layer.Can further reduce rigidly connected sectional area in the spoke like this, strengthen the effect of vibration and noise reducing, satisfy the processing technology requirement of spoke simultaneously.

The specific embodiment
As shown in the figure, wheel of the present invention is combined by wheel rim 1, spoke 6 and axle sleeve 3 three parts, and different with existing wheel is, the outside of spoke 6 is wrapped up a circle vibration damping layer 4 along its length, and vibration damping layer 4 is made of fiber-reinforced plastic.Two pluckings centres of spoke 6 thin and at both ends formation internal shoulder 62 and outer convex shoulder 61, vibration damping layer 4 is wrapped in the elongated position between internal shoulder 62 and the outer convex shoulder 61, spoke 6 forms interference fit with wheel rim 1, the axle sleeve 3 at two ends, so just form prestressed structure, pressure direction suffered when this prestress moves with wheel is opposite, therefore can improve the force-bearing situation of wheel, strengthen the effectiveness in vibration suppression of wheel.
The inner edge of wheel rim 1 is provided with groove 11, insert in the groove 11 end of spoke 6, the both sides of wheel rim 1 are respectively equipped with wheel rim left side bead stopper 2 and the right bead stopper 5 of wheel rim, and wheel rim left side bead stopper 2, the right bead stopper 5 of wheel rim are by being bolted on the wheel rim 1 and the end of spoke 6 being clamped; The root end face 64 of spoke 6 is an arc-shaped concave, directly cooperates with the periphery of axle sleeve 3; Be provided with axle sleeve briquetting 8 between the root of per two spokes 6, axle sleeve briquetting 8 is fixed on the periphery of axle sleeve 3 by flathead screw, and in a circumferential direction the root of spoke 6 is clamped; One side of axle sleeve 3 is provided with annular boss 31, opposite side is provided with wheel shaft bead stopper 7, wheel shaft bead stopper 7 is by being bolted on the axle sleeve briquetting 8, annular boss 31 and wheel shaft bead stopper 7 clamp the root of spoke 6 vertically, spoke 6 just is connected between wheel rim 1 and the axle sleeve 3 reliably like this, has guaranteed wheel integral intensity and rigidity requirement.
The middle part of spoke 6 is one section thinner pipe link 63, fills low density foam material 9 between pipe link 63 and the vibration damping layer 4.Can further reduce rigidly connected sectional area in the spoke like this, strengthen the effect of vibration and noise reducing, satisfy the processing technology requirement of spoke simultaneously.
