Abstract
The invention discloses an auxiliary clamp for measurement of the torsional rigidity of an elastic wheel. The auxiliary clamp is composed of a machine fame (5), a supporting frame (6), a wheel hub supporting and braking mechanism and a wheel core loading mechanism, wherein the supporting frame (6) can be connected to the machine frame (5), the wheel hub supporting and braking mechanism is composed of two clamping blocks (4) capable of being connected to the machine frame (5), and the wheel center loading mechanism is composed of an interference shaft (2) and a loading arm (3). According to the auxiliary clamp, the shaft and the elastic wheel are installed together in a pressed mode and are in interference fit; the shaft is located on the supporting frame through the cooperation of annular grooves and circular grooves of the supporting frame and can rotate around the shaft in the axial direction; one end of the loading arm applies pressure, only torsional deformation is generated between a wheel center and a wheel hub of the elastic wheel at the moment, and the torsional rigidity of the elastic wheel is measured through the pressure, stroke and moment arm length of a pressure tester.
Description
Technical field
The present invention relates to urban rail transit vehicles measure auxiliary clamp with elastic wheel torsional rigidity.
Background technology
Urban rail transit vehicles street surface or overhead on travel the vibration and noise of the generation shadow to surrounding
Ring increasingly notable, this becomes one of outstanding problem of urban track traffic.In order to alleviate Wheel Rail Vibration and noise, city rail is handed over
Be open to traffic and gradually begin to use elastic wheel, this wheel elastic elements between core wheel and wheel hub, therefore core wheel relatively with
Wheel hub has the deformation rigidity in 6 directions as shown in figure 1, being respectively around x to deflection stiffness, around y to torsional rigidity, around z to inclined
Turn rigidity, to radial rigidity, to axial rigidity, z is to radial rigidity for y for x.Wherein radial rigidity determines that the maximum that it can bear is hung down
Straight dead load, if its insufficient rigidity is matched with the load born therewith, hub for vehicle wheel will deform it is possible to lead to wheel hub
The serious consequences such as fracture, overturning；Axial rigidity determines wheel to the lateral displacement relatively with track, if rigidity is too small being likely to result in
Fall track or derailing.Further, since brake force and pull strength are all provided by wheel-rail friction power, the wheel hub in vehicle braking and starting
Huge frictional force can be produced and rubber interlayer between, once sliding, that is, elastic wheel torsional rigidity is not enough, may lead to
Wheel hub comes off.But the rigidity between wheel hub and core wheel is excessive and the advantage of the wheel that follows the string itself, so in a certain model
Elastic wheel come into operation before must by test its rigidity given clearly, by design vehicle suspension parameter with elastic
Wheel stiffnesses are mated, to ensure that dynamics of vehicle performance reaches most preferably.
Content of the invention
Due to the importance of elastic wheel rigidity, the purpose of patent of the present invention is to provide a kind of bullet based on pressure testing machine
Property wheel torsional rigidity test of vehicular measurement auxiliary equipment；And make it have structure simple, and easy for installation, low cost, Project Realization is held
Easy advantage.
The purpose of the present invention is to be proposed based on following analysis and scheme and realize:
A kind of elastic wheel torsional rigidity measures auxiliary clamp: by frame 5, the carriage 6 that can be connected in frame 5, can
The wheel hub that two gripping blocks 4 being connected in frame 5 are constituted supports arrestment mechanism and the wheel being made up of interference axle 2 and loading arm 3
Core load maintainer is formed；Carriage 6 upper end has two circular grooves 601, and lower end has and fixing with frame 5 couples dress
Put；Two cannelures 201 being matched with carriage 6 upper end two circular groove 601 are had on interference axle 2, the two of interference axle 2
Individual termination is respectively provided with rectangular recess 202；Have on the loading arm 3 of y shape and fasten with 2 two termination rectangular recess 202 of interference axle
Two bayonet sockets 301；Bolt hole 402 for assigning clamping screw is provided with gripping block 4；Gripping block 4 bottom be provided with
The fixing coupling arrangement of frame 5.
This equipment is operationally based on following principle: should be guaranteed that elastic wheel wheel hub and core wheel when measuring torsional rigidity
Between only torsional direction degree of freedom, and the active force of pressure testing machine is only deformed to this one degree of freedom.

Specific embodiment
Below in conjunction with the accompanying drawings the structure of the present invention is described in further detail.
Fig. 2 and Fig. 3 is a kind of specific embodiment of elastic wheel torsional rigidity test of vehicular in the present invention, tests installation process
As follows:
By interference axle 2 and detected wheel 1 interference fit, that is, interference axle 2 and wheel core wheel be consolidated no relative
Motion, interference axle 2 axle is as shown in figure 4, have cannelure 201 and rectangular recess 202 thereon.By on cannelure 201 and carriage 6
The circular groove 601 at end coordinates, and interference axle 2 can be around carriage 6 axial rotation.There are two locating dowels 602 carriage 6 lower end,
Locating dowel 602 is inserted positioning and the fixation that carriage 6 is completed on corresponding location hole 501 in frame 5.Limited by gripping block 4
With respect to the rotation of core wheel, gripping block 4 lower end has the location hole 502 that cylindrical locating dowel 401 is inserted in frame 5 to position to ratch hub
Fixing, wheel edge can be put in wherein by gripping block 4 hollow, and there is bolt hole 402 gripping block lower end, can be by vehicle wheel by bolt
Hub clamps；Loading arm 3 one end has bayonet socket 301 to coordinate with rectangular recess 202 on interference axle 2, between loading arm 3 and interference axle 2 no
Axial rotation, now applies pressure (as the in figure direction of arrow) in the loading arm other end, wheel hub only reverses change with respect to core wheel
Shape, can calculate elastic wheel torsional rigidity by the pressure of testing machine, stroke, torque arm length measurement.
