Abstract
Disclosed is a novel streetcar which has two sets of engines-hydraulic transmission boxes. The utility model is provided with an engine linkage stepless speed regulation device and an automatic gear shifting device of the streetcar, and the two sets of machine sets can be used separately or jointly. The utility model has the advantages of easy operation, big tractive power (20 full-load Standard lorries), low cost, good smoothness and saved fuel, which is particularly suitable for the cargo traction and the personnel transportation of the harbors, mines, factories and railway sections.
Description
The utility model belong to a kind of twin-engined-railcar of hydraulic transmission box.
With driving engine-hydraulic transmission box be the railcar of power and type of drive mainly be meant the 89201136.X patent of our factory described it be as engine installation by one group of driving engine-hydraulic transmission box, realize the speed change of railcar by manual shift, car body is located adopting rod-pulling type with wheel, is that two moving axis drive.Along with the development of large enterprises such as harbour, mine, freight department's a kind of power of needs is big, cost is low, handles simple and reliable little running railcar.The product of present domestic large automobile plant produced is a monomotor, the locomotive of power more than 1000KW, and the price height, the oil consumption height for harbour, mine, forms the situation that high-power draws dolly.
The purpose of this utility model is: a kind of railcar that is applicable to large enterprises such as harbour, mine is provided, has easy and simple to handlely, stationarity is good, the big and good economy performance of tractive force.
The technical solution of the utility model is: two groups of driving engine-hydraulic transmission boxes are installed in respectively on the crossbeam of railcar, whole locomotive body and crossbeam link by side bearing and two no drawing strickle guide formula welding bogies, by transmission shaft the hydraulic transmission box outputting power is passed to axle gear box, again by taking turns to driving railcar.Two groups of driving engine-hydraulic transmission boxes drive four moving axis of former and later two bogie trucks respectively, throttle place at two driving engines respectively is provided with a cylinder, need only the handle of on driving position, moving pressure regulating valve during work, realize the infinite speed variation of driving engine by the variation of air pipe pressure, no matter so railcar be separate unit work or two all scalable of working simultaneously.On hydraulic transmission box, respectively be provided with an automatically controlled gearshift, detect the electric signal that the rotating speed of the speed of a motor vehicle of railcar and driving engine gets by tachogenerator, and relatively control automatically controlled gearshift by comparator with this electric signal, realize the self shifter of railcar.No drawing strickle guide welded type bogie truck is " day " font, and the cross-sectional plane of each beam is that box type construction is welded, and curb girder is fish belly shape, has reduced quality, has saved steel, has satisfied the balance requirement of railcar.
The utility model has the advantages that: adopt two groups of driving engine-hydraulic transmission boxes, can use separately, can use simultaneously again, tractive force is big, and is widely applicable; Be furnished with throttle pneumatic adjusting valve and automatically controlled gearshift, realized the self shifter of driving engine infinite speed variation and railcar, easy and simple to handle, safe and reliable; Whole locomotive body and crossbeam are installed in two " day " on the font bogie truck, and than the railcar of two moving axis traction, tractive performance has essence to change.And price of the present utility model approximately only has 1/3rd of big locomotive.
Below in conjunction with embodiment and accompanying drawing thereof, the utility model is elaborated:
Fig. 1: structural representation of the present utility model
Fig. 2: transmission of power scheme drawing of the present utility model
Fig. 3 a, b: of the present utility model " day " font case shows structure welded type bogie truck scheme drawing
Fig. 4: the stepless deadbeat intention of withering of driving engine
Fig. 5: the utility model self shifter scheme drawing
As shown in Figure 1, the utility model comprises crossbeam 1, and hood 2, driving engine 8, driver's cab 3, hydraulic transmission box 4, traction side bearing 5, bogie truck 6, wheel are provided with two operator platfories to 7 etc. in the driver's cab 3, but both-way operation, whole locomotive body and crossbeam are installed on the bogie truck 6 by traction side bearing 5.As shown in Figure 2, the power of driving engine 8 passes to wheel respectively the axle gear box on 7 is driven railcar by hydraulic transmission box 4.Figure 3 shows that " day " structural representation of font welding bogie 6, each beam is box type construction, and curb girder is a fish belly shape, sees that Fig. 1 two bogie trucks 6 are respectively at the two ends of railcar.Fig. 4 is pressure regulating valve on driver's cab 3 interior two operator platfories 9 and the scheme drawing that is installed in the throttle cylinder 10 on the driving engine 8, rotation by pressure regulating valve, change the variation of regulating pneumatic adjusting valve 10 by the pressure in the air pipe 11, realize the stepless change of driving engine 8.Fig. 5 is self-shifting principle schematic, detects by 12,13 pairs of speed of a motor vehicle of tachogenerator and engine speed and obtains electric signal, through comparator 14 relatively, when railcar starting and low speed, comparator 14 output low levels, relay 15 keeps normality, and this car runs on I shelves operating mode, when this car constantly quickens, its signal voltage is greater than giving constant potential, and comparator 14 is exported high level, relay 15, promote electromagnetic valve 16 railcars and run on II shelves operating mode, thereby realize autoshift.
