Description
Technical field
The utility model is relevant for the outstanding device of engine truck drive system frame, particularly relevant for the outstanding device of 3 full elastic shelfs of a kind of engine truck drive system.
Background technology
Railway locomotive, city railway train etc. mainly comprise part such as equipment on car body (or under-carriage), running part, coupler and draft gear, brake equipment and the car.Wherein running part is between car body and track, effect is to bear car body and go up weight of equipment and transmitting tractive, braking force, and pilot engine orbiting, running part generally adopts the form of bogie truck, and provides the power of advancing for bogie truck by the motor gearbox drive system that hangs on car body bottom (or truck frame).
At present, the bogie truck of domestic advanced quasi high-speed, rapid transit railway locomotive, the hang of its motor gearbox drive system is the outstanding modes of 3 rigid mounts of bogie truck integral, this hang is applicable to the running velocity of 140km/h～180km/h scope.Show through test and calculating chart, after locomotive running speed surpasses 140km/h, wheel-rail lateral force can increase sharply, although drive system is one to be sprung weight, but still be two to be unsprung weight, along with the raising of locomotive speed, because of circuit irregularity and the wheel that impact causes strengthen vertical and horizontal dynamic load, the revolution moment of inertia of bogie truck increases, and this stability of crawling during to the bogie truck high-speed cruising is totally unfavorable, directly influences the dynamic performance of locomotive.Therefore, the outstanding device of 3 rigid mounts of this kind drive system is only applicable on the quasi high-speed locomotive.
In order to solve bogie truck owing to the outstanding aforementioned deficiencies that caused of 3 full rigid mounts, make locomotive when high-speed cruising, can further alleviate the wheel track crosswise movement firmly, improve the comformability of locomotive to circuit and parameter variation, and improve the transversal dynamic performance of locomotive, guarantee the good dynamic performance and the stability of crawling of locomotive, people have developed the outstanding device of frame of 3 full resilient suspensions of drive system.For example, just disclosed the outstanding technology of frame of 3 full resilient suspensions of a kind of drive system in disclosed Chinese CN1817706A publication number patent case on August 16th, 2006.Referring to Fig. 1,2, the outstanding device of these 3 full elastic shelfs comprises: lean on the suspension arm 18 of hollow shaft side to be connected on the Connection Block 26 of truck frame crossbeam 28 by a suspension arm rubber arthrosis 19 at traction electric machine 10; The opposite side of traction electric machine 10 is a hanging structure, hanging structure comprises two groups of suspending assemblies, every group of suspending assembly comprises a suspension rod 15, one end of suspension rod 15 is connected with Connection Block 25 elasticity on the truck frame crossbeam 29 by elastic element 27, and the other end of suspension rod 15 is connected with flap seat 17 elasticity by suspension rod rubber arthrosis 16, flap seat 17 is connected by fastener with the housing of traction electric machine 10, also the housing of traction electric machine 10 directly can be made to have the flap seat form.Traction electric machine 10 has just realized that by suspension arm 18, two groups of suspending assemblies 3 full elastic shelfs on bogie truck are outstanding like this, can adapt to and effectively reduce bogie truck laterally, vertically, multidirectional vibration acceleration such as reverse, improved the working environment of drive system greatly, has less wheel-rail lateral force simultaneously, guaranteed that locomotive has good riding quality, guaranteed anti-crawl stability, traveling stationarity and the good dynamic performance of locomotive under high-speed cruising.But in the manufacturing process of reality, in the locomotive operation process, find that still there is following deficiency in the outstanding device of existing 3 full elastic shelfs at present:
