Abstract
The invention particularly discloses an auxiliary transmission system of a high-power electric transmission type heavy rail car and aims to solve the problems of power dispersion, large occupied space, complex gearbox structure and high cost, caused by an unreasonable structure, of an existing auxiliary transmission system. Single-stage involute type cylindrical spiral gears are arranged on an input shaft and an output shaft of a primary reducing gear box; a duplex different-diameter belt pulley is connected to an output end of the input shaft of the primary reducing gear box; two output ends of the output shaft of the primary reducing gear box are connected with a hydrostatic pump and an air compressor driving belt pulley, respectively; a spare air compressor and a ventilator are arranged on the right side of the duplex different-diameter belt pulley; transmission shafts of the spare air compressor and the ventilator are connected with a spare air compressor belt pulley and a ventilator belt pulley; an air compressor is arranged on the left side of the duplex different-diameter belt pulley; the transmission shaft of the air compressor is connected to the air compressor belt pulley. By virtue of the auxiliary transmission system, power sources in parts of a car body are integrated to one part of a free end of a diesel engine.
Description
Technical field
The present invention relates to the component 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 drop-gear 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 input shaft of high elastic coupling, telescoping versatile spindle driven gear case at the free end of diesel engine, and input shaft drives respectively two output shafts by gear transmission.An output shaft drives hydrostatic pump work by spline coupling, and another root output shaft drives respectively starter-generator and ventilating set work by fast coupling, nylon rope plunging joint.
This structure 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 case, and be connected with the input shaft of primary speed-down gear case, the input shaft of primary speed-down gear case, on output shaft, be provided with intermeshing single-stage evolvent type cylindric spiral gear, the mouth of primary speed-down gearbox input shaft is connected with duplex irregular diameter belt wheel, two mouths of primary speed-down gearbox output shaft are connected with respectively hydrostatic pump and Air compressor driving pulley, the right side of duplex irregular diameter belt wheel is provided with Air compressor for subsequent use and ventilating set, and on the transmission shaft of Air compressor for subsequent use and ventilating set, be connected with and duplex irregular diameter belt wheel bel-drivenn belt of air compressor wheel for subsequent use and ventilating set belt pulley, the left side of duplex irregular diameter belt wheel is provided with Air compressor, and on Air compressor transmission shaft, be connected with Air compressor driving pulley bel-drivenn belt of air compressor and take turns.
When operation, the free end of diesel engine drives the input shaft rotation of Telescopic cardan shaft, primary speed-down gear case, input 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 HM Hydraulic Motor, and then cooling fan work on driving cooling mechanism, thereby carry out cooling to diesel coolant; Meanwhile, the Air compressor driving pulley of the output shaft other end drives Air compressor work by belt-driving; Duplex irregular diameter belt wheel drives respectively ventilating set and Air compressor work for subsequent use by belt-driving, and ventilating set provides cooling with wind for two traction motors, and Air compressor and Air compressor for subsequent use are locomotive provides pressurized air with wind devices and locomotive brake; Air compressor for subsequent use is worked in the time of track car weight connection operating mode together with Air compressor, and when non-heavy operating mode, if Air compressor et out of order, Air compressor for subsequent use can replace it to work independently; Simultaneously, two Air compressors adopt mounting means staggered relatively, by this mounting means and reasonably distribute transmitting ratio, can make two Air compressors in identical mode of operation, 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 case is diaxon drop-gear box, and body structure is simpler; The propulsion source being dispersed in car body is everywhere integrated into diesel engine free end one place simultaneously, meets the thought of modular design, have advantages of simple in structure, easy to maintenance and cost is low.
