Embodiment Construction

[0016] See Figure 1~4 As shown, the vehicle shear type elastic wheel of the present invention comprises a tire 1 with mounting ring grooves 1-1 on both sides, a wheel center 3 with a gap 3-1, a pressure ring 2 and two elastic discs 5, The ring 2 is set at the gap 3-1 of the wheel center 3 and is fastened to the wheel center 3. The tire 1, the pressure ring 2 and the wheel center 3 can be connected by more than four uniformly distributed fasteners 4. The ring 2 and the wheel center 3 are evenly arranged with 8 to 24 installation holes along their circumference, and the shaft sleeve 6 is installed in the installation holes. The fasteners 4 can be bolts and lock nuts, and each bolt is installed in the corresponding installation hole and Locking by a lock nut, or the present invention adopts a snap ring connection, and the pressure ring 2 is connected to the wheel center 3 through the snap ring, so that the tire 1, the wheel center 3, the pressure ring 2 and the elastic disc 5 ar...

Abstract

The invention relates to a shear-type elastic wheel for rail transit vehicles. The shear-type elastic wheel for rail transit vehicles comprises a wheel rim, a wheel center, a pressing ring and two elastic discs, wherein the wheel rim is provided with installation annular grooves in the two sides, and the wheel center is provided with a notch. The pressing ring is arranged in the notch of the wheel center and connected with the wheel center through fasteners; each elastic disc is an elastomer with an inner metal plate and an outer metal plate connected to the two sides in an embedded mode, inner protruding blocks on the lateral sides of the two elastic discs are respectively matched with a corresponding inner groove in a connecting disc of the wheel rim in a buckled mode, outer protruding blocks on the lateral sides of the two elastic discs are matched with a corresponding outer groove in the lateral side of the wheel center and a corresponding outer groove in the lateral side of the pressing ring respectively in a buckled mode, then, the two elastic discs are symmetrically connected between the wheel center and the wheel rim in a pressed mode and between the pressing ring and the wheel rim in a pressed mode respectively; outer radial clearances h1 exist between the outer peripheries of the elastic discs and the outer hole walls of the wheel rims, inner radial clearances h2 exist between the inner peripheries of the elastic discs and a shaft neck of the wheel center and between the inner peripheries of the elastic discs and a shaft neck of the pressing ring, and the included angle alpha between the elastic discs and the vertical tangent plane ranges from 0 degree to 20 degrees. The shear-type elastic wheel for rail transit vehicles is reasonable in structure, capable of reducing manufacturing and use cost, convenient to maintain and good in vibration and noise reduction effect.

Description

technical field [0001] The invention relates to a shear type elastic wheel for rail transit vehicles, which belongs to the technical field of elastic wheels for light rail vehicles. Background technique [0002] With the rapid development of urban rail transit vehicles, more and more urban rail transit vehicles use elastic wheels. The elastic wheel removes the metal from direct contact by inlaying rubber elements between the wheel center and the rim, reduces the force between the wheel and the rail, eases the impact, improves the stability of the vehicle running, and improves the operating conditions of the wheel and the axle. Elastic wheels can be divided into pressure-bearing type, shear-bearing type and compression-shear compound type from the structure. The pressure-bearing elastic wheel is that the rubber component bears pressure under the action of vertical load and impact load; the shear-bearing elastic wheel is that the rubber component bears shear force under the a...
