Abstract
The utility model discloses an elastic joint structure applicable to cantilever type flexible suspension of a traction motor of a bullet train. For implementing the horizontal decoupling of the mass of the motor and a framework due to the horizontal flexible suspension of the traction motor of a bogie of the high-speed bullet train, a cross beam of a locomotive framework is provided with a lifting lug and a pair of longitudinal oscillating bars which are horizontally arranged, the lifting lug and the pair of longitudinal oscillating bars are distributed in a triangle shape, three motors are arranged and distributed in a triangle shape, an installation flange is connected with the lifting lug and the pair of longitudinal oscillating bars to form flexible suspension and connection, and elastic elements are adopted as connecting joints between the longitudinal oscillating bars and the cross beam. The elastic joint structure provides a horizontal flexible suspension way for the cantilever type suspended motor of the high-speed bullet train, has the advantages of compact space, simple assembling structure, mature and reliable components, and easiness in realization based on the bogie of a two-axis bullet train, and can release the horizontal movement of the motor relative to the framework of the bogie to realize the decoupling of the mass of the motor and the framework so as to effectively improve the quality of horizontal dynamics in the high-speed running of the bullet train.
Description
Technical field
The utility model belongs to railway locomotive, especially high-speed locomotive steering frame manufacturing technology field.Technical field.
Background technology
The utility model is replenishing of the applicant's " the high speed motor car cantilevered hangs motor lateral flexibility hang " patent application.
Drive motor is suspended under framework or the car body underframe by fork or other elastic element, be domestic and international a kind of up-to-date technology of express locomotive, motor car bogie in recent years, the transversal dynamic performance when this frame mode can improve locomotive, motor-car high-speed cruising effectively.Power decentralized formula High-Speed Power Vehicle drive motor often adopts cantilevered fashion to be installed on the truck transom, and this mode realizes that structurally lateral flexibility hangs comparatively difficulty.Power decentralized formula High-Speed Power Vehicle drive motor lateral flexibility hang mainly contains two classes both at home and abroad, the motor suspension mode that the first kind such as German ICE3 and Chinese CRH3 motor train unit power car adopt, two drive motor of two-axle bogie are fixed on the motor mount, and utilize 4 than long elastic steel strips, mount pad is suspended under the truck transom to realize that lateral flexibility hangs, and this hang complex structure also takies than large space; The big flexible big joint of the original rigidity of joint replacement of another kind of employing, by the trifilar suspension drive motor on truck transom, utilize the lateral deformation in joint to realize that the lateral flexibility of drive motor hangs, this hang is very high to the hanging element performance demands, offshore company is carrying out the experimental investigation of this respect at present, yet there are no the real-world operation power car and adopts this hang.The utility model hangs motor at cantilevered, proposes a kind of lateral flexibility hang, utilizes a cross motion of hanging the fork coupling realization motor of joint and two levels vertical (the parallel or Eight characters) layout, has advantage simple and reliable for structure.
The utility model content
In view of the deficiency of the existing program of above statement, the utility model aims to provide a kind of lateral flexibility hang, makes it to have that mounting structure is simple, the advantage of element mature and reliable.This structure can discharge the cross motion of the relative truck frame of motor, makes motor and the horizontal decoupling zero of framework quality, the transversal dynamic performance when improving the motor-car high-speed cruising effectively.
The purpose of this utility model realizes by following means.
A kind of elastic joint structure of suitable motor-car traction electric machine cantilevered flexible suspension, for the high speed motor car bogie truck of implementing the motor that lateral flexibility hangs provides horizontal decoupling zero, it is characterized in that, crossbeam at locomotive bogie arranges hanger and a pair of horizontally disposed vertical fork, and hanger and a pair of vertical fork are " product " shape and distribute; Motor also is provided with three, is " product " shape and distributes; Protruding rafter and hanger are installed to link to each other with a pair of vertical fork and forms flexible suspension and connect; Vertically fork adopts elastic element with the joint that is connected of crossbeam.
The utility model provides the good operation condition for the motor lateral flexibility hang that the high speed motor car cantilevered hangs, this joint has bigger elastic range, bigger damping and elastic parameter are easy to adjust control, has space compactness (can further omit and be provided with shock absorber and stop configurations between motor and the framework), mounting structure is simple, element mature and reliable and the advantage that easily realizes on diaxon motor car bogie basis, can discharge the cross motion of the relative truck frame of motor, make motor and the decoupling zero of framework quality, the horizontal dynamic quality when improving the motor-car high-speed cruising effectively.

Fig. 3, the utility model motor suspension front view.
Fig. 4, motor suspension upward view.
Among the figure: 1-one is vertical damper; 2-journal box body; 3-wheel is right; 4-one is spring; 5-framework; 6-air bellow; 7-a pair of vertical fork (7a and 7b); 8-crossbeam; 9-hanger; 10-gear case suspension rod; 11-motor lateral damper; 12-motor; 13-gear case, 13-gear case; 14-two is lateral damper; 15-anti-the shock absorber that crawls; 16-cog-wheel coupling; 17-packing ring; 18-elastic element; 19-nut; 20-crossbeam flange.
The specific embodiment
Below in conjunction with accompanying drawing enforcement of the present utility model is further described.
Can see that by Fig. 3,4 the motor-car motor is the cantilevered trifilar suspension, at the crossbeam 8 of locomotive bogie hanger 9 and a pair of horizontally disposed vertical fork 7a and 7b are set, hanger 9 and a pair of vertical fork are " product " shape and distribute; Motor also is provided with three, is " product " shape and distributes; Protruding rafter and hanger are installed to link to each other with a pair of vertical fork and forms flexible suspension and connect; Vertical fork 7a that hanger 9 by having certain joint stiffness and two horizontal parallel longitudinals are arranged and 7b with motor 12 trifilar suspensions on the crossbeam 8 of framework 5, and between motor 12 and framework 5, arrange lateral damper 11, utilize the elastic joint teeter of vertical fork 7 on framework to realize that the lateral flexibility of motor 12 hangs.In the present embodiment, elastic element 18 is made of two cylindrical rubber that are clamped on the crossbeam flange 20 for being clamped in the cylindrical rubber on the crossbeam flange.
Other structure of power car bogie truck remains unchanged, and 13 of motor 12 and gears case pass through cog-wheel coupling 16 carry-over moment drive wheels to 3.Wheel is that vertical damper 1 and be spring 4 through journal box body 2 be connected with framework 5 by one to 3.Framework 5 is that lateral damper 14 is connected with the anti-shock absorber 15 that crawls with car body by air bellow 6, two, with the function that realizes integrating supporting, guiding, vibration damping and driving and braking.Utilization is equipped with the hanger of elastic joint and the fork of two levels vertical (the parallel or Eight characters) layout, realizes that cantilevered hangs the lateral flexibility suspension of motor.Vertically after being connected the joint and adopting this larger volume elastic element of fork and crossbeam, can provide certain damping, in most of the cases can make lateral flexibility hang more simple compactness 11 cancellations of motor lateral damper.
