Abstract
The invention provides a rear axle door for an electric wheel dumper truck and the electric wheel dumper truck. The electric wheel dumper truck comprises a rear axle door plate, wherein a ventilation grate is arranged on the rear axle door plate, and multiple grate plates forming the ventilation grate are arranged obliquely and upward, so that air flows on the inner side of the rear axle door plate flow out along the ventilation grate obliquely and upward. By arranging the ventilation grate with the oblique and upward guiding direction on the rear axle door, the air flows in a truck body can be upward guided out of the truck body, dust on the ground does not fly upward, and running of vehicles in the front and back is not influenced. In addition, the ventilation grate with the oblique and upward guiding direction can enable the possibility that sands and stones on the road surface enter a rear axle to be reduced and ensure normal work of a traction motor and the like in the rear axle.
Description
Technical field
The present invention relates to electric power wheel self-discharging vehicle rear axle structure technology, relate in particular to a kind of electric power wheel self-discharging vehicle rear axle door and electric power wheel self-discharging vehicle.
Background technology
The traction motor of mine electric wheel dump and back axle brake disc need to discharge a large amount of heats in vehicle operating process, are provided with drafting apparatus in back axle assembly, and the final outlet that rear axle door is whole drafting apparatus, is arranged on the rear-axle casing of back axle.
Mine electric wheel dump is in the very harsh surface mine of condition, to work at the scene, mine road is native stone section substantially, in prior art, when the air-flow that in back axle assembly, drafting apparatus produces is discharged to car body from rear axle door, can cause that mine road stirs up a cloud of dust, reduce the visbility between forward and backward vehicle, affect the driving safety of forward and backward car.
Summary of the invention
The invention provides a kind of electric power wheel self-discharging vehicle rear axle door and electric power wheel self-discharging vehicle, while carrying out ventilation and heat for solving prior art by rear axle door, can cause that mine road stirs up a cloud of dust, affect the problem of road surface visbility.
The invention provides a kind of electric power wheel self-discharging vehicle rear axle door, comprise back axle door-plate, on described back axle door-plate, be provided with ventilation fence, a plurality of screens that form described ventilation fence arrange obliquely, so that the air-flow of described back axle door-plate inner side flows and discharges obliquely along described ventilation fence.
The present invention also provides a kind of electric power wheel self-discharging vehicle on the other hand, comprises rear-axle casing and electric power wheel self-discharging vehicle rear axle door as above, and described electric power wheel self-discharging vehicle rear axle door is arranged on vent window place set on described rear-axle casing.
Electric power wheel self-discharging vehicle rear axle door provided by the invention and electric power wheel self-discharging vehicle, by guide direction ventilation fence is obliquely set on rear axle door, air-flow in car body upwards can be derived outside car body, and can not cause ground stirring up a cloud of dust, vehicle operating before and after impact.Meanwhile, guide direction ventilation fence obliquely can reduce the probability that sandstone on road surface enters back axle inside, guarantees the normal work such as traction electric machine in rear-axle casing.

Another sectional structure schematic diagram of the electric power wheel self-discharging vehicle rear axle door that Fig. 3 provides for the embodiment of the present invention.
The specific embodiment
The invention provides a kind of electric power wheel self-discharging vehicle rear axle door, this rear axle door is particularly useful for mine electric wheel dump, as shown in Figure 1, this electric power wheel self-discharging vehicle rear axle door comprises back axle door-plate 1, on back axle door-plate 1, be provided with ventilation fence 2, a plurality of screens that form this ventilation fence 2 arrange obliquely, when rear axle door 1 is arranged on the vent window on rear-axle casing, the guide direction of 2 pairs of air-flows of ventilation fence is for obliquely, and the air-flow of back axle door-plate 1 inner side can flow and discharge obliquely along ventilation fence 2.The concrete structure of ventilation fence 2 as shown in Figure 2, each screen of ventilation fence 2 is rolled over obliquely by level that (ventilation fence 2 is not limited to structure shown in Fig. 2, also can be as shown in Figure 3, as long as meet the guide direction of ventilation fence for obliquely), the rear axle door that air-flow provides by the present embodiment is in the process of car body outside drain, air-flow flows in atmosphere along ventilation fence 2 direction obliquely, to prevent from blowing to ground, causes that ground stirs up a cloud of dust.
In the present embodiment, as shown in Figures 1 and 2, back axle door-plate 1 is the middle circular slab that has square opening 11, and the periphery of this square opening 11 is provided with vent window wall 3, vent window wall 3 encloses formation square cavity, and a plurality of screens of ventilation fence 2 are fixed on the both sides of this square cavity.
It will be understood by those skilled in the art that back axle door-plate 1 is also not limited to circular slab, also can be squarely etc., it is square that ventilation fence 2 is also not limited to that square cavity limits, and guide direction is that the ventilation fence of any shape is obliquely all within protection scope of the present invention.
In the present embodiment, on back axle door-plate 1, be provided with a plurality of journal stirrups 4, for back axle door-plate 1, be connected to the set vent window place of rear-axle casing (not shown).Concrete, journal stirrup 4 is four, is symmetricly set on the both sides of back axle door-plate 1, and the vent window place of rear-axle casing can arrange the ear seat that is connected use with journal stirrup 4, is provided with connecting bore 41 on journal stirrup 4, can journal stirrup 4 be connected with the ear seat on rear-axle casing by pin etc.
In the present embodiment, the submarginal position of medial surface of back axle door-plate 1 is provided with the steady ring 5 for locating, during application, the rear axle door that the present embodiment provides can be stuck on the vent window on rear-axle casing by steady ring 5 smoothly and correctly, then by pin etc., journal stirrup 4 is fixed on the ear seat at vent window place, with fixing rear axle door.
The rear axle door that the present embodiment provides, by guide direction ventilation fence is obliquely set on back axle door-plate, can upwards derive the air-flow in car body outside car body, and can not cause ground stirring up a cloud of dust, vehicle operating before and after impact.Meanwhile, guide direction ventilation fence obliquely can reduce the probability that sandstone on road surface enters back axle inside, guarantees the normal work such as traction electric machine in rear-axle casing.
