Abstract
The utility model discloses an eight-axle locomotive towing device. The towing device adopts BOBO-BOBO axle type, namely, each locomotive is provided with a front bogie truck and a rear bogie truck, each bogie truck comprises two BO type bogie trucks, a towing seat is fixed under the locomotive body and is provided with a group of single tow rods and a group of double tow rods which are connected with the end beams of the two bogie trucks on the locomotive; three lifting lugs are arranged on the bottom surface of the towing seat structure and respectively connected with the tow rods through globe joints, the single tow rods are connected with the end beam of the left bogie truck, and the double tow rods are connected with the end bean of the right bogie truck. By adopting the structure, under the premise of compact and simple bogie truck space, the arrangement is reasonable, kinematic interference can not be generated, the axle load transfer can be reduced while ensuring the dynamic performance of the bogie truck, and the requirement on the starting tractive force can be satisfied.
Description
Affiliated technical field
The utility model belongs to rolling stock, and especially locomotive traction transmission mechanism device is made the field.
Background technology
Along with the raising of locomotive traction power, eight locomotives can obtain higher towability as a kind of mode of traction under the situation of avoiding two-shipper heavily to join.Eight advanced locomotives generally adopt the BOBO-BOBO shaft type, two bogie trucks before and after promptly every locomotive has, and every bogie truck is made up of two BO formula bogie trucks.Eight locomotives are widely used in Russia, up till now for extremely, and Э ∏ 100 passenger locomotive single-unit power 9600kw, maximum speed can reach 200km/h.Because the bogie structure complexity, the dress leading-in device that can satisfy the requirement of tractive force transmission and Full Vehicle Dynamics becomes design difficulty.If adopt traditional draw gear, be difficult to satisfy compact space requirement again.
The utility model content
Above shortcoming in view of prior art, the purpose of this utility model is a kind of eight-shaft device for tracting locomotive of design, overcome the above shortcoming of prior art, make it to have concurrently the stable characteristics of dynamic performance of the simple in structure and BOBO-BOBO axis structure car load of traditional single pole draw gear.And connection and reasonable arrangement does not produce movement interference, reduces axle and heavily shift when guaranteeing the dynamic performance of bogie truck.
The purpose of this utility model is to realize by following means.
Eight-shaft device for tracting locomotive, adopt the BOBO-BOBO shaft type, two bogie trucks before and after promptly every locomotive has, every bogie truck is made up of two BO formula bogie trucks, traction seat is fixed under the car body, and traction seat has one group of single draw bar and links to each other with two bogie truck end carriages on the locomotive with one group of two draw bar; There are three hangers described traction seat structure bottom surface, is connected with draw bar respectively by ball and socket, and described single draw bar connects left steering frame end beam, and two draw bars connect right steering frame end beam.
After adopting design as above, the utility model device adopts structure of the present utility model, and under the compact simple prerequisite in bogie truck space, connection and reasonable arrangement does not produce movement interference.Transformed ripe single pole traction technique, every BO formula bogie truck end carriage and car body are by becoming 7 ° of angle diagonal draw bar transmitting tractive power with horizontal surface.Draw gear does not retrain framework other degree of freedom except that vertically, guaranteed the dynamic performance of bogie truck, tractive force directly is delivered to car body by framework in addition, without intermediate frame, helps the dynamic performance of car load and has improved the framed intensity safety performance.Tilting draw bar is compared the horizontal arrangement draw bar can reduce Axle Weight Transfer of Locomotive by Using, can improve the starting tractive effort of locomotive.This design space reasonable structural arrangement can satisfy the space requirement of bogie truck compactness, and rotary joint quantity is convenient to daily attention less in addition.

The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
The whole BOBO-BOBO shaft type that adopts, two bogie trucks before and after promptly every locomotive has, every bogie truck is made up of two BO formula bogie trucks.Can find out the basic structure of the present utility model and the specific embodiment in conjunction with Fig. 1 and 2.1-bogie frame among the figure; The 2-car body; The 3-intermediate frame; The 4-traction seat; The single draw bar of 5-; The two draw bars of 6-.Traction seat 4 is fixed under the car body 2, traction seat 4 have one group of single draw bar 5 and one group of two draw bar 6 respectively with locomotive on two bogie truck end carriages 7 link to each other with 8, tractive force directly is delivered on the car body from truck end sill, without intermediate frame.There are three hangers 9,10,11 traction seat 4 structure bottom surfaces, are connected with draw bar respectively by ball and socket, can realize the nod angular transposition and the angular transposition of shaking the head that draw bar is bigger.
Among single draw bar structure such as accompanying drawing 3, the figure, 5 is single draw bar, and 10 is hanger in the middle of the traction seat, and 12 is ball joint bearing, and 13 is rubber coating, and 14 is towing pin.Single draw bar 5 is connected with hanger in the middle of the traction seat by ball and socket 12, and the other end is connected with towing pin 14 by rubber coating 13, and towing pin 14 is fixed on the truck end sill 7.
Two draw bar structures such as accompanying drawing 4, among the figure, 6 and 6 ' be draw bar, 9 and 11 is traction seat both sides hangers, and 15 is two rod sleeves, and 16 is towing pin, 17 rubber coatings, and 18 and 19 is ball joint bearing.Draw bar 6 and 6 ' one end is connected with traction seat both sides hanger respectively, and the other end is connected with two rod sleeves 15 with 19 by ball-bearing casing 18 respectively.Two rod sleeves 15 are connected with towing pin 16 by rubber coating 17, and towing pin 16 is fixed on the truck end sill 8.
Two bar sides are made up of two draw bars and two rod sleeve, connect by ball and socket, and two draw bar structures are parallel four limit row mechanisms, and the ball and socket oiling is rotated flexibly.Draw bar and end carriage are by towing pin and traction sleeve mode transmitting tractive power, and towing pin is fixed on the truck end sill, with bell-and-spigot joint position rubber sleeve, and can shock absorbing power and isolate the longitudinal vibration of bogie truck high frequency.The axial line of the axial line of described single draw bar and two draw bars all constitutes 7 ° of angles with horizontal surface (ground).(α and α ' angle among Fig. 2 b) helps reducing Axle Weight Transfer of Locomotive by Using.
Above structural arrangement mode, draw bar can produce angular transposition by the joint, is easy to the free motion of adapted framework except that vertically.Little by truck end sill and car body ways of connecting point with the space, compare the truck transom connection mode, can avoid traction electric machine and bring the nervous problem in space.
