Abstract
The utility model discloses a wheel pair for direction-turning support of subway, which comprises an axle and two wheels relatively arranged at two ends of the axle, the a noise-reducing dampener is arranged on two relative inner sides of the wheels, the noise-reducing dampener is inserted at the wheel rim between the inner wheel flange and the wheel hub. As adopting the wheel pairs, i.e the noise-reducing dampener which is overlapped by a plurality of metal plates and dampening sheets is arranged at inner side of the wheel pairs, the vibration-absorbing noise-reducing frequency rang of the noise-reducing dampener can be adjusted by adjusting elasticity and dampening of dampening sheets and the physical dimension and thickness (tuned mass), so that the main noise simulation frequency of the wheels are covered.
Description
Technical field
The utility model relates to a kind of bogie truck of railroad vehicle, and it is right to be specifically related to the wheel used on a kind of subway car bogie truck.
Technical background
Bogie truck be tractive force of train, braking force, car load and track external force directly hold the receptor, most important to the riding quality and the passenger traffic safety of vehicle.Bogie truck by framework, single stage suspension device, wheel to, axle box, secondary suspension device, draw gear, foundation brake rigging, component set-ups such as tooth-like shaft coupling, traction electric machine and gear reduction box, wheel wherein is to being integral by an axletree and two press mountings of car wheel, it is the Orbiting critical component of the whole bogie truck of carrying, in the vehicle operating process, wheel is being to bearing the total weight of vehicle, and also bearing other motive powers that transmit from car body, rail two aspects during high-speed cruising in orbit.Take turns right quality and directly influence train operating safety.Wheel-rail noise is one of overriding noise source in the vehicle ', and wheel-rail noise is divided into two classes: whistler causes owing to the wheel stick-slip that normally the frequency height can reach 100-110dB; Thunder noise owing to wheel track produces at the contact zone mutual action.During the wheel track contact, the geometrical defect on wheel and the rail causes the wheel track relative displacement, and then produces noise.Be to reduce noise, the EN13979-1 standard code of on EN13103 and EN13104 standard base, determining wheel to design-calculated machinery and hot computer limit value.These standards some about noise radiation, wherein the right noise level of the new wheel of regulation must be lower than former product, yet in newly-built urban track traffic, the curved in tracks radius is less, understand between wheel and the rail owing to friction, sideslip, extruding etc. produce serious high frequency birdie, thereby bring new city noise pollution.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of vehicle that can reduce by curve the time, and the wheel of using on the subway car bogie truck of the sharp-pointed high frequency noise that is produced between the wheel track is right.
The technical scheme that realizes above-mentioned purpose is: the wheel of using on a kind of subway car bogie truck is right, comprises the relative wheel that is installed in the axletree two ends with two of axletree, and two relative medial surfaces of described wheel are provided with the noise reducing damping device.
The wheel of using on the above-mentioned subway car bogie truck is right, and wherein, described noise reducing damping device is installed in the inboard wheel rim of wheel and the wheel rim place between the wheel hub.
The wheel of using on the above-mentioned subway car bogie truck is right, wherein, described noise reducing damping device is formed by stacking by stacked conducting plate and damp film, be the installation metal sheet with rim for automobile wheel bonded assembly plate, other metal sheets are the tuning quality metal sheet, interlayer is a damp film between the metal sheet, and stacked conducting plate and damp film are riveted together with stainless steel rivet.
Owing to adopted the wheel of using on the subway car bogie truck of the present utility model right, promptly taking turns the noise reducing damping device that right installed inside stacked conducting plate and damp film are formed by stacking, by the elasticity of adjusting damp film and the oad and the thickness (tuning quality) of damping and metal sheet, can regulate the vibration-absorbing denoising frequency limit of noise reducing damping device, make it cover the overriding noise model frequency of wheel.8 noise reducing damping devices are installed in the maximum position of vibration on the wheel symmetrically and evenly with screw---on the wheel rim, just can absorb the vibration of wheel effectively, vibrational energy is converted into thermal dissipation fast by damping and falls.It has eliminated the high-frequency noises composition that wheel is in operation effectively, has reduced noise.
Description of drawings
Fig. 1 is the right structural representation of using on the subway car bogie truck of the present utility model of wheel;
Fig. 2 be among Fig. 1 A to view;
Fig. 3 is the enlarged drawing of B among Fig. 1.
The specific embodiment
See also Fig. 1, the wheel of using on the subway car bogie truck of the present utility model is right, comprise the relative wheel 2 that is installed in axletree 1 two ends of axletree 1 with two, wherein, two relative medial surfaces of wheel 2 are provided with noise reducing damping device 3, and this noise reducing damping device 3 is installed on the inboard wheel rim 21 and the wheel rim 23 between the wheel hub 22 of wheel 2.
Noise reducing damping device 3 is formed by stacking by stacked conducting plate and damp film, be the installation metal sheet with rim for automobile wheel 23 bonded assembly plates 30, other metal sheets 31 are the tuning quality metal sheet, and interlayer is a damp film 32 between the metal sheet, and stacked conducting plate and damp film are riveted together with stainless steel rivet.
Wheel is in operation and is collided, pushes, when rubbing equal excitation, will be in the vibration that radially, laterally produces each mode, and outside radiated noise, the position of vibration amplitude maximum is on wheel rim on the wheel, in order to obtain best noise reduction, simultaneously guarantee that again safety in operation, mounting means of the present utility model are that 8 noise reducing damping devices are installed on the wheel rim of wheel two relative medial surfaces symmetrically and evenly, each noise reducing damping device is connected with the wheel rim 23 of wheel with three screws 4.
Behind verification experimental verification, adopt the mounting means of such noise reducing damping device can eliminate the high-frequency noises composition that is in operation.
Test comprises the noise testing under the friction speed shelves when noise reducing damping device is not installed, when the noise reducing damping device is installed, in no excitation with noise testing under two kinds of operating condition of test of excitation, the friction speed shelves is arranged.
The wheel that the noise reducing damping device is housed is right, with do not adorn the common of noise reducing damping device and take turns comparing, in all measuring points, main test speed grade, the simulate ideal circuit do not have the having under two kinds of test conditions of exciting operating mode of exciting operating mode and the operation of simulation actual track, sound pressure level all has obvious decline.Rolling rig test contrast table is as follows:
Table one: no excitation operating condition of test
Annotate: the parameter of 1, beating has howling.
2, plunging joint disconnects, and motor does not change, and T/S is equipped with the sound insulation canopy.
Table two: the excitation operating condition of test is arranged
Annotate: the parameter of 1, beating has howling.
2, plunging joint disconnects, and motor does not change, and T/S is equipped with the sound insulation canopy.
Above embodiment is only for the usefulness that the utility model is described, but not to restriction of the present utility model, person skilled in the relevant technique, under the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
