Detailed Description
Fig. 1 is the utility model discloses a schematic structure diagram, an auxiliary transmission of engineering locomotive, characterized by, including the gear box, be provided with input shaft 9 and output shaft 3 in the gear box, turn left from the right side on the input shaft 9 and set gradually input flange 1, drive gear 6 and drive gear two 8, the gear box top surface is provided with the first fluid coupling 11 of drive cooling fan, and the gear box left side is provided with the second fluid coupling 12 of drive air compressor machine, is provided with on the first fluid coupling 11 with the driven gear 7 of the 6 meshing of drive gear.
As shown in fig. 2, one end of the output shaft 3 is connected to the second hydraulic coupler 12, and the output shaft 3 is provided with a second driven gear 10 engaged with the second driving gear 8. The utility model discloses a cooling fan and air compressor machine are driven respectively to first hydraulic coupling 11 and second hydraulic coupling 12, can be through its control valve control oil charge and oil extraction, when the oil charge, the coupler work, cooling fan or air compressor machine work promptly, and when the oil extraction, the coupler stop work, cooling fan and air compressor machine stop work to cooling fan and air compressor machine have been realized according to the setting value realization automatic control requirement, reduce the consumption.
The gearbox comprises an upper box 4 and a lower box 5. The input flange 1 is connected with the free end of the diesel engine through a cardan shaft. The right side of the gear box is provided with a gear pump 2, the gear pump 2 arranged on the box body is used for sucking working oil in the box body to oil inlets of the first hydraulic coupler 11 and the second hydraulic coupler 12, and meanwhile, the gear pump provides lubrication for bearings and gears in the gear box. The first driven gear 7 is connected to the first fluid coupling 11 through bolts. The first driving gear 6 and the first driven gear 7 are bevel gears, the rotating direction of the first driving gear 6 is changed by 90 degrees after the first driving gear 6 is meshed with the first driven gear 7, and then the first driven gear rotates, so that the installation requirements of the cooling fan are met, the tooth number of the bevel gears is changed, the transmission ratio of the bevel gears can be changed, and the rotating speed requirements of different cooling fans are met.
