Abstract
The elastic suspension of steering frame drive device comprises the drive device, three suspension hanging arms fixed at one end, the other end of the hanging arm connected to the rubber ball joint, hanging rod and the corresponding formation beam. Side of the drive device sets a hydraulic absorber or horizontal gag lever post, both ends connected to the rubber ball joint, connecting the drive device and the side frame. It partially releases the restraint between the drive device and the frame, greatly improves the horizontal dynamic feature of the locomotive.
Description
Technical field
The invention belongs to the railway locomotive technical field, relate in particular to a kind of later-model resilient suspension mechanism of locomotive steering bogie driving device.
Background technology
Bogie truck driving equipment suspension mode is the key factor that influences locomotive operation quality and running velocity.Original main axle suspension and the outstanding dual mode of rigid mount of adopting of engine truck driving equipment suspension mechanism.The axle suspension mode is actually a kind of half and hangs, and promptly half of actuating device weight hangs on the framework of bogie truck, and second half then is directly to be pressed on the axletree, will influence the driveability of axletree like this, and the maximum speed of locomotive can only reach 140km/h.Though and the outstanding mode of rigid mount has realized the integral of actuating device, maximum speed can reach 180km/h reluctantly, but because actuating device and framework are rigidly connected fully, vibration that actuating device produces and impact are delivered on the framework fully, and then be delivered to driver's cab, speed up improves again, and the lateral performance of locomotive will obviously worsen, the vibration aggravation.Therefore, how the rigid constraint between releasing driving device and the framework just becomes a new problem.Three axle truck particularly, the bogie truck breast wheel cross travel bigger by curve the time to needs, therefore in the axle box assembling to breast wheel to being provided with bigger free transverse momentum.If connect after the rigid constraint that has discharged between actuating device and the framework by elasticity, the transverse momentum of tween drive shaft is excessive, can make between the each several part device again to bump.
Summary of the invention
Purpose of the present invention overcomes the deficiency of above-mentioned prior art exactly, and a kind of novel locomotive bogie truck actuating device elastic shelf suspension mechanism that improves locomotive high-speed cruising quality is provided.
The objective of the invention is existing like this: a kind of resilient suspension mechanism of locomotive steering bogie driving device, form by the frame suspension arm (2) that actuating device (3) and three one ends are fixed on it, it is characterized in that described before the other end of arm (2) link to each other with cooresponding frame girder (6) by rubber spherical joint (1), the other end of arm (2) is hung on the cooresponding frame girder (6) by rubber spherical joint (1) and suspension rod (4) after two.
In order to realize purpose of the present invention better, the side of actuating device (3) is provided with an oil-pressure damper (5), and its two ends couple together actuating device (3) and bogie side frame (7) by rubber spherical joint (1).
In order to realize purpose of the present invention better, the side of actuating device (3) is provided with a cross spacing bar (5), and its two ends couple together actuating device (3) and bogie side frame (7) by rubber spherical joint (1).
After adopting the solution of the present invention, because between actuating device and framework all is that elasticity is connected, partly discharged the constraint between actuating device and the framework, thereby can improve the transversal dynamic performance of locomotive widely, can satisfy requirement up to the 200km/h running velocity.Particularly on three axle truck: for the end axle, the employing of oil-pressure damper makes the lateral vibration of the relative framework of actuating device have certain damping, and the lateral vibration of the relative framework of decay actuating device also makes and laterally obtain certain decoupling zero simultaneously; For tween drive shaft, the employing of cross spacing bar structure has overcome because elasticity connects after the rigid constraint that has discharged between driver element and framework, and the problem that tween drive shaft and lateral play of wheel set thereof are excessive makes the motor oscillating amplitude be no more than the restriction place value.
Description of drawings
Accompanying drawing 1 is the schematic top plan view of the embodiment of the invention.
Accompanying drawing 2 is that A-A in the accompanying drawing 1 is to generalized section.
Accompanying drawing 3 is that the B-B of rubber spherical joint among attached Fig. 1 and 2 is to generalized section.
The specific embodiment
Referring to accompanying drawing, resilient suspension mechanism of locomotive steering bogie driving device of the present invention, motor and gear case are rigidly connected into as a whole actuating device unit (3), are provided with three frame suspension arms (2) on actuating device unit (3).One end of frame suspension arm (2) is rigidly secured to actuating device unit (3) by bolt, before the other end of arm (2) link to each other with cooresponding frame girder (6) by rubber spherical joint (1), the other end of arm (2) is hung on the cooresponding frame girder (6) by rubber spherical joint (1) and suspension rod (4) after two.Described rubber spherical joint (1) is made up of mandrel (10), overcoat (9), rubber layer (9) three parts.Mandrel (10), overcoat (9) all are steel part.Owing between two parts of rubber spherical joint (1) institute bonded assembly certain longitudinal travel and yaw displacement can be arranged.So the preceding suspension centre of unit can take place around the rotating of vertical axis and lateral shaft relative to framework, bigger relative displacement takes place in the relative framework of the back suspension centre of unit simultaneously, has so just avoided the unit to move with framework.For the end axle in the three axle truck, in the side of actuating device unit (3) oil-pressure damper (5) is set, its two ends couple together by rubber spherical joint (1) and actuating device (3) and bogie side frame (7).The employing of oil-pressure damper (5) makes the lateral vibration of the relative framework of actuating device (3) have certain damping, and decay actuating device (3) is the lateral vibration of framework relatively, also makes simultaneously and laterally obtains certain decoupling zero.Tween drive shaft for three axle truck, label (5) in actuating device (3) side just adopts a cross spacing bar to substitute oil-pressure damper, driver element and bogie side frame (7) are coupled together, rubber spherical joint (1) is adopted at position-limited lever (5) two ends equally, make the motor oscillating amplitude be no more than the restriction place value, and play the lateral vibration effect of the relative framework of attenuation units simultaneously, with the cross motion of the relative framework in unit be limited in certain scope (± 2mm).
