Abstract
The invention discloses an elastic joint structure suitable for cantilever-type flexible suspension of a CRH (China railway high-speed) train traction motor. The elastic joint structure is used for executing transverse flexible suspension of a CRH train bogie traction motor so as to achieve quality transverse decoupling of a motor and a frame. A lifting lug and a pair of horizontally arranged longitudinal swing links are arranged on a crossbeam of the train frame and are distributed in a shape of Chinese character Pin; the motor is also provided with three flanges distributed in a shape of Chinese character Pin; the flanges are connected with the lifting lug and the pair of longitudinal swing links to form flexible suspension connection; and elastic components are adopted for the connection joints between the horizontal swing links and the crossbeam. The elastic joint structure provided by the invention provides a transverse flexible suspension manner for the cantilever-type suspension motor of the CRH train, and has the advantages of compact structure, simple assembly structure, and mature and reliable components, is easy to realize on a two-axis train bogie base, and the like. The elastic joint structure can release the transverse movement of the motor relative to the bogie frame so as to achieve quality decoupling of the motor and the frame, thereby effectively improving transverse dynamic quality of the CRH train during high-speed movement.
Description
Technical field
The invention belongs to railway locomotive, especially high-speed locomotive steering frame manufacturing technology field.Technical field.
Background technology
The present invention 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 vehicle body bottom frame by fork or other elastic element, a kind of up-to-date technology of recent domestic express locomotive, motor car bogie, the transversal dynamic performance when this frame mode can improve locomotive, motor-car high-speed cruising effectively.Power dispersion type High-Speed Power Vehicle drive motor often adopts cantilevered fashion to be arranged on truck transom, and this mode realizes that structurally lateral flexibility hangs comparatively difficulty.Power dispersion type 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 motor mount, and utilize 4 long elastic steel strips, mount pad is suspended under truck transom to realize that lateral flexibility hangs, and this hang complex structure also takies than large space; The large joint of the original rigidity of joint replacement of the larger flexibility 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 requirement of hanging element performance, 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 present invention is directed to cantilevered and hang motor, propose a kind of lateral flexibility hang, utilize a fork of hanging joint and two levels vertical (the parallel or Eight characters) layout to mate the cross motion of realizing motor, have advantages of simple and reliable for structure.
Summary of the invention
In view of the deficiency of the existing program of above statement, the present invention aims to provide a kind of lateral flexibility hang, makes it to have advantages of that mounting structure is simple, the 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 effectively improving the motor-car high-speed cruising.
Purpose of the present invention realizes by following means.
The elastic joint structure that a kind of applicable motor-car traction motor cantilever flexible hangs, 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, hanger and a pair of horizontally disposed vertical fork are set on the crossbeam of locomotive bogie, and hanger and a pair of vertical fork are " product " shape and distribute; Motor also is provided with three and is the protruding rafter of " product " shape distributing installation and is connected with a pair of vertical fork with hanger and forms flexible suspension and connect; Vertically fork adopts elastic element with the joint that is connected of crossbeam.
the present invention provides good service conditions for the motor lateral flexibility hang that the high speed motor car cantilevered hangs, this joint has larger elastic range, larger damping and elastic parameter are easy to adjust and control, has space compactness (can further omit and be provided with shock absorber and stop configurations between motor and 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, horizontal dynamic quality when effectively improving the motor-car high-speed cruising.
Description of drawings is as follows:
Fig. 1, bogie truck front view of the present invention.
Fig. 2, bogie truck birds-eye view of the present invention.
Fig. 3, motor suspension front view of the present invention.
Fig. 4, motor suspension upward view.
In figure: 1-one is vertical damper; The 2-journal box body; The 3-wheel is right; The 4-primary spring; The 5-framework; The 6-air bellow; The a pair of vertical fork of 7-(7a and 7b); The 8-crossbeam; The 9-hanger; 10-gear case suspension rod; 11-motor lateral damper; The 12-motor; The 13-gear case, the 13-gear case; 14-two is lateral damper; The anti-hunting Damper of 15-; The 16-cog-wheel coupling; The 17-packing ring; The 18-elastic element; The 19-nut; 20-crossbeam flange.
The specific embodiment
Below in conjunction with accompanying drawing, enforcement of the present invention is further described.
Can be seen by Fig. 3,4, the motor-car motor is the cantilevered trifilar suspension, and hanger 9 and a pair of horizontally disposed vertical fork 7a and 7b are set on the crossbeam 8 of locomotive bogie, and hanger 9 and a pair of vertical fork are " product " shape and distribute; Motor also is provided with three and is the protruding rafter of " product " shape distributing installation and is connected with a pair of vertical fork with hanger 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 arrange lateral damper 11 between motor 12 and framework 5, 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 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 with primary spring are connected through journal box body 2 are connected with framework 5 by one to 3.Framework 5 and car body are lateral damper 14 and be connected hunting Damper 15 to be connected 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 motor lateral damper 11 can be cancelled, make lateral flexibility hang more simple compactness.
