Abstract
The utility model belongs to equipment for subways, in particular to a subway shunter. The utility model solves the problems that the existing subway shunter has low traction under work speed, a bogie structure is complex, a cooling system can not adjust work according to temperature, and the like. The power system of the subway shunter comprises an engine management generator and a hydraulic machinery speed changing box for railway which is connected with the engine management generator, and a bogie adopts a center pin traction structure. An oil pump of the cooling system adopts a variable pump, and an oil way between the oil pump and a motor is provided with a temperature control valve capable of feeling system temperature. The subway shunter has the advantages that the subway shunter is especially suitable for overloading operation and can completely meet the requirement of large-slope subway train traction after dual-machine reconnection; the bogie structure is simple, a unit brake and a sand box are conveniently installed, and the subway clearance requirements are easily met; the rotating speed of a fan can be adjusted according to the cooling temperature needed by the system, therefore the power consumption of the fan is reduced, and the power utilization efficiency of vehicle is increased.
Description
Technical field
The utility model belongs to subway equipment, is specifically related to a kind of subway machine of shunting.
Background technology
There is following problems in the existing subway machine of shunting:
1, power unit adopts the used power unit of construction machinery and equipment, and (30～40km/h) is bigger with respect to hyperbola decline degree, and promptly tractive force is lower under work speed when work speed for the traction curve.
2, bogie truck is two welding bogies, adopts secondary suspension and drawing pull bar, and rod member is more, complex structure.
3, cooling system adopts hydrostatic pressure system drive fan cooling water expansion tank, air inlet and wet goods, be that oil pump adopts fix-displacement pump, the rotating speed of the motor of drive fan is corresponding with engine speed, can not regulate, so fan speed according to the proportional variation of engine speed, can not be adjusted according to temperature requirement all the time.
Summary of the invention
The utility model shunts in order to solve existing subway that tractive force is lower under the machine work speed, bogie structure is complicated, cooling system can not be by problems such as temperature adjusting works.
The utility model adopts following technical scheme to realize:
The subway machine of shunting, comprise underframe, preceding propulsion plant, driver's cab, back propulsion plant and chilling room are set on the underframe, two bogie trucks before and after underframe is installed down, power system is arranged within the propulsion plant of back, the cooling system that is used to cool off power system is arranged at and comprises oil pump within the chilling room, it is characterized in that described power system comprises EFI formula electrical generator and connected railway with fluid power-mechanical gear box, and bogie truck adopts the center pin hitch structure; The oil pump of cooling system adopts controllable capacity pump, and the temperature control valve that can experience system temperature is set on the oil circuit between oil pump and the motor.
The utlity model has following beneficial effect:
1, after the power system coupling, under work speed 30-40km/h, the 450 subways machine travel power of shunting is suitable with 600 horsepowers of machines of shunting, the more approximate and hyperbola of traction curve, be particularly suitable for heavy service, and two-shipper can satisfy the requirement of steep gradient subway train traction after heavily joining fully.
2, change the mode of traction of bogie truck after, bogie structure is simple, unit brake and sandbox are easy for installation, satisfy the requirement of subway gauge easilier.
3, rotation speed of the fan can be adjusted according to the required chilling temperature of system, thereby has reduced fan power consumption, has promoted the power utilization of car load.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Fig. 2 is a hydraulic system principle figure of the present utility model
Among the figure: propulsion plant before the 1-, 2-driver's cab, propulsion plant behind the 3-, 4-chilling room, 5-underframe, 6-bogie truck, 7-hydraulic reservoir, 8-oil pump, 9-temperature control valve, 10-motor, 11-fan.
The specific embodiment
In conjunction with the accompanying drawings the specific embodiment of the present utility model is described further.
The subway described in the utility model machine of shunting comprises underframe 5, and underframe 5 tops are provided with forward and backward propulsion plant, driver's cab 2 and chilling room 4; Underframe 5 bottoms are bogie truck 6.Power system is arranged at back propulsion plant 3, and the cooling system that is used to cool off power system is arranged at and comprises oil pump 8 within the chilling room 4.
Power system comprises EFI formula electrical generator (as: american commings QSX15-C450 driving engine) and connected railway with fluid power-mechanical gear box (as: Japanese NICO company aim at TDCN-22-1806 fluid power-mechanical gear box that railway is produced), and both are installed in behind the direct connection in the propulsion plant 3 of back.
Bogie truck 6 adopts two welding bogies, and mode of traction adopts the center pin traction.
The oil pump 8 of cooling system adopts controllable capacity pump, and the temperature control valve 9 that can experience temperature of dynamical system (temperature that comprises engine water, gas or gear box oil) is set on the oil circuit between oil pump 8 and the motor 10.Temperature control valve 9 comprises temperature-sensing element, spool part, and its structure those skilled in the art can obtain from prior art.For example at the water outlet of engine cooling water one temperature control valve is installed, temperature control valve is experienced the height of water temperature, makes its in-to-in expansion of liquids or contraction, thereby promotion valve core movement, come the control variable capacity of pump with this amount of exercise, thus control motor flow, and then adjust rotation speed of the fan.The temperature height of power system like this, the cooling energy that needs is big, and rotation speed of the fan is just fast; Otherwise the temperature of power system is low, and the cooling power that needs is little, and rotation speed of the fan is then slow.
