Abstract
The utility model discloses a transverse flexible hanging structure applied to a cantilever type hanging motor of a bullet train. The transverse flexible hanging structure applied to the cantilever type hanging motor of the bullet train hangs the motor of the bullet train in a cantilever type three-point suspension mode. A transverse beam (8) of the engine framework is provided with a lifting lug (9) and a pair of horizontally-arranged longitudinal swing bars (7a and 7b), and the lifting lug and the pair of longitudinal swing bars are distributed in a triangular mode; three motors (13) are also distributed in a triangular mode; a mounting flange and the lifting lug and the pair of longitudinal swing bars are connected to form a flexible hanging connection; a shock absorber (11) is arranged between the motors (12) and a framework (5). The transverse flexible hanging structure applied to the cantilever type hanging motor of the bullet train provides the transverse flexible hanging structure for the cantilever type hanging motor of the high-speed bullet train, has the advantages of being compact in space, simple in assembly structure, mature and reliable in elements and easy to achieve on the basis of a double-shaft bullet train bogie, can release transverse motion of the motors relative to a bogie frame to enable the motors to decouple with the framework mass, and effectively improves the transverse dynamics quality during 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
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 suspension construction mainly contains two classes both at home and abroad, the motor suspension structure 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 suspension construction 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 suspension construction 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 suspension construction.The utility model hangs motor at cantilevered, proposes a kind of lateral flexibility suspension construction, 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 suspension construction, 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 lateral flexibility suspension construction that is applied to motor-car cantilevered suspension motor, with motor-car motor cantilevered trifilar suspension, it is characterized in that, at the crossbeam of locomotive bogie hanger and a pair of horizontally disposed vertical fork are set, 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; Be provided with shock absorber between motor and the framework.
The utility model provides a kind of lateral flexibility suspension construction for the motor that the high speed motor car cantilevered hangs, has the space compactness, 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.
