Abstract
The utility model belongs to the technical field of power transmission systems, in particular to a power transmission system of an operation vehicle for rapid transit railway contact network, which is used for solving the problem that the existing power transmission system can not satisfy the requirement of a 120-kilometer high-speed operation vehicle. The power transmission system of the operation vehicle comprises an engine and transmission shafts, wherein the output shaft of the engine is connected with the input shaft of a hydraulic-machine speed changing box, and the output shaft of the hydraulic-machine speed changing box is connected with an axle gear box installed respectively on each axle through a cardan shaft. The power transmission system of the operation vehicle has the beneficial effects that the configuration of the power system is easy and simplified, the pulling characteristic is good, gear shifting impact is low, the mutual locking of gear and vehicle speed is easy to realize, the operation is simple, the overall dimension is small, and the efficiency is high; and the power transmission system of the operation vehicle is suitable for the operation vehicle space with smaller space.
Description
Technical field
The utility model belongs to the technical field of power drive system, is specifically related to a kind of applied to high-speed railway touching net Operation Van power drive system, particularly 120 kilometers applied to high-speed railway touching net Operation Van power drive systems.
Background technology
Domestic 120 kilometers high speed Operation Vans still are in the starting stage at present, and mainly there are three kinds of patterns in power drive system:
(1), the alternating current transmission, this scheme power transmission mainly adopts diesel powerplant and friendship-straight-hand over type of drive, the subject matter of this type of drive is:
1, many, the complex structure of parts.System unit comprises diesel powerplant, AC traction electric motor, traction invertor, rectifier cabinet, braking resistor, operating console etc., and electric elements is many, has increased trouble point and operation easier.
2, the technology level of application is not high.Though exchanging transmission is mature technology on main-line locomotive, does not also use this kind type of drive at present in Operation Van, the operating personal skill level is not high, and later stage service and training amount are very big.
(2), mechanical drive mode, the subject matter of this mode is:
1 if the requirement of the time traction 50t that satisfies 120km/h is difficult to choose suitable change speed gear box at home.
2, tractive characteristic is poor.
3, because the gear of mechanical gear box own is many, operating difficulties.
(3), hydraulic transmission, this type of drive adopts pure hydraulic transmission gear box, by the various combination of a plurality of tor-cons, realizes gear shift, the commutation of Operation Van, the subject matter that this type of drive exists:
1, hydraulic transmission gear box generally has four tor-cons, and the transmission gearbox size is bigger, causes whole difficult arrangement;
2, present domestic hydraulic transmission gear box power grade is more than 600 horsepowers, and selectable range is very narrow, the type selecting difficulty.
Summary of the invention
The utility model is in order to solve the problem that existing power drive system can not satisfy the requirement of 120 kilometers high speed Operation Vans.
The utility model adopts following technical scheme to realize:
Applied to high-speed railway touching net Operation Van power drive system, comprise driving engine and each transmission shaft, the output shaft of driving engine connects the input shaft of fluid power-mechanical gear box, and the output shaft of fluid power-mechanical gear box connects the axle gear box of installing respectively on the every axletree by versatile spindle.
The utility model adopts the hydro-mechanical transmission mode in applied to high-speed railway touching net Operation Van, after the whole power system coupling, maximum speed reaches 132km/h, and the traction tonnage reaches 50 tons when the speed of a motor vehicle reaches 120km/h.
The relative prior art of the utility model has following beneficial effect:
1, compare with the electric tramsmission mode, the hydro-mechanical transmission parts are few, are easy to arrange.Compare with split type hydraulic transmission box simultaneously, the tor-con of Japanese NICO and change speed gear box are integral type, have simplified the power system layout more.
2, compare with mechanical drive mode, the hydro-mechanical transmission tractive characteristic is good, and also owing to adopt electric liquid shift, shifting shock is little, is easy to realize the interlocking of gear, the speed of a motor vehicle, and simple to operate.
3, compare with domestic existing pure hydraulic transmission, this type of drive oad is little, is more suitable for less Operation Van space, space.This hydraulic transmission box efficient height simultaneously, each grade efficient can reach 94% respectively, and the efficient of whole drive system can reach 88%, effectively reduces the heating loss.

Fig. 1 is power transmission line figure of the present utility model
Fig. 2 is a structural representation of the present utility model
Among the figure: 1-driver's cab, 2-bogie truck, 3-axle gear box, 4-versatile spindle, 5-underframe, 6-fluid power-mechanical gear box, 7-car bonnet, 8-driving engine.
The specific embodiment
In conjunction with the accompanying drawings the specific embodiment of the present utility model is described further.
The car load transmission of applied to high-speed railway touching net Operation Van is with a fluid power-mechanical gear box 6 by a driving engine 8, by versatile spindle 4 power is passed to axle gear box 3 by fluid power-mechanical gear box 6 again, one chassis shaft gear case 3 all is installed on the every axletree, drive wheel, realize the transmission of power of traction, see Fig. 1.
Driving engine can adopt imported with original packaging U.S. Cummins QSX-15 electronic fuel injection engine, 550 horsepowers of engine rated powers.Hydraulic transmission box can adopt the TDCN-22-2062 change speed gear box of imported with original packaging Japan NICO company, this change speed gear box is combined turbine transformer and mechanical gear box, has two gears, adopts electric liquid shift and commutation, and idle running pump is installed, can realize that long distance tows.Axle gear box adopts dual-ratio reduction case, reduction ratio 3.0.The power drive system that adopts above-mentioned parts to form, starting tractive effort can reach 75kN, and the unit highest running speed can reach 132km/h, and highest running speed can reach 120km/h during traction 50t.
