Description
Technical field
The present invention relates to the part of electric driven heavy rail car, be specially a kind of high-power electric driven heavy rail car accessory drive system.
Background technology
Accessory drive system is the important component part of electric driven heavy rail car, is the important mechanism of guaranteeing car load safe operation.
Existing accessory drive system is all parts work in the power-driven system by disperseing, it is cooling with wind that the traction motor that system is locomotive by a centrifugal fan provides, and drives hydrostatic motor to provide power for cooling fan by being arranged on hydrostatic pump on reduction box; Simultaneously it is also for air compressor and the stand-by compressor of locomotive provide power, and air compressor is to provide compressed-air actuated important equipment for locomotive brake and with wind devices.
Existing accessory drive system rotates by the power shaft of highly elastic shaft coupling, extension type universal drive shaft driven gear case at the free end of diesel engine, and power shaft drives respectively two output shafts by gear drive. An output shaft drives hydrostatic pump work by spline coupling, and another root output shaft drives respectively starter-generator and ventilation blower work by positive coupling, nylon rope shaft coupling.
This structural design can not provide power for air compressor, air compressor needs an independent DC motor drive, and being auxiliary diesel generater set, power supply of dc motor provides, this design makes accessory drive system power decentralized, and not only take for air compressor provides the auxiliary diesel generater set of power and dc motor the space that car body is very large, and increased cost; Secondly, the gear box structure more complicated using in this transmission scheme, design and manufacture cost is higher.
Summary of the invention
The present invention, in order to solve existing accessory drive system because unreasonable structure causes power decentralized, the problem large, gear box structure is complicated and cost is higher that takes up room, provides a kind of high-power electric driven heavy rail car accessory drive system.
The present invention adopts following technical scheme to realize: high-power electric driven heavy rail car accessory drive system, comprise the Telescopic cardan shaft being connected with diesel engine free end, the other end of Telescopic cardan shaft is provided with primary speed-down gear-box, and be connected with the power shaft of primary speed-down gear-box, the power shaft of primary speed-down gear-box, on output shaft, be provided with intermeshing single-stage evolvent type cylindric spiral gear, the output of primary speed-down gearbox input shaft is connected with duplex irregular diameter belt wheel, two outputs of primary speed-down gearbox output shaft are connected with respectively hydrostatic pump and air compressor machine drive pulley, the right side of duplex irregular diameter belt wheel is provided with air compressor machine for subsequent use and ventilation blower, and on the power transmission shaft of air compressor machine for subsequent use and ventilation blower, be connected with and duplex irregular diameter belt wheel bel-drivenn belt of air compressor wheel for subsequent use and ventilation blower belt pulley, the left side of duplex irregular diameter belt wheel is provided with air compressor machine, and on air compressor machine power transmission shaft, be connected with air compressor machine drive pulley bel-drivenn belt of air compressor and take turns.
When operation, the free end of diesel engine drives the power shaft rotation of Telescopic cardan shaft, primary speed-down gear-box, power shaft rotates by single-stage evolvent type cylindric spiral gear driver output axle again, one end of output shaft drives hydrostatic pump entry into service, hydrostatic pump drives hydraulic motor, and then cooling fan work on driving cooling device, thereby carry out cooling to diesel coolant; Meanwhile, the air compressor machine drive pulley of the output shaft other end drives air compressor machine work by belt transmission; Duplex irregular diameter belt wheel drives respectively ventilation blower and air compressor machine work for subsequent use by belt transmission, and ventilation blower provides cooling with wind for two traction motors, and air compressor machine and air compressor machine for subsequent use are locomotive provides compressed air with wind devices and locomotive brake; Air compressor machine for subsequent use is worked in the time of track car weight connection operating mode together with air compressor machine, and when non-heavy operating mode, if air compressor machine breaks down, air compressor machine for subsequent use can replace it to work independently; Simultaneously, two air compressor machines adopt mounting means staggered relatively, by this mounting means and reasonably distribute gearratio, can make two air compressor machines in identical duty, overcome existing accessory drive system because unreasonable structure causes power decentralized, the problem large, gear box structure is complicated and cost is higher takes up room.
Reasonable in design of the present invention is reliable, and compact overall structure takies vehicle body space less, and gear-box is diaxon reduction box, and body structure is simpler; The power source being dispersed in car body is everywhere integrated into diesel engine free end one place simultaneously, meets the thought of modularized design, have advantages of simple in structure, easy to maintenance and cost is low.
