Description

A kind of front wheel driving ejector half crawler vehicle walking chassis structure
Technical field
The utility model relates to engineering machinery field, particularly a kind of front wheel driving ejector half crawler vehicle walking chassis structure.
Background technology
The traveling gear complex structure of crawler vehicle, the walking of the crawler vehicle on market at present all adopts back-wheel drive, and running motor is arranged on trailing wheel.This structure is for some ramp type operating mode, and when uphill/downhill, track adjusting wheel is very large to the load of stretching device, and its consumption of power is also very large, what is more important is in down-hole, crawler vehicle needs often to go up a slope, and weight distribution is concentrated and rear vehicle, and when rear-mounted driving, caterpillar wheel is impaired often very fast.
Utility model content
The purpose of this utility model is to provide that a kind of energy consumption is little, the impaired light front wheel driving ejector half crawler vehicle walking chassis structure of ore deposit to the caterpillar machinery of the frequent uphill/downhill of needs of interior operation that be applicable to of caterpillar wheel.
The technical scheme that the utility model provides is: a kind of front wheel driving ejector half crawler vehicle walking chassis structure, comprise vehicle frame, the both sides of described vehicle frame are provided with drive wheel, guide wheel, tightening device, caterpillar wheel, holder chain mechanism, described drive wheel, guide wheel, tightening device, caterpillar wheel, holder chain mechanism connects by crawler haulage, described tightening device is connected with described guide wheel, also comprise running motor, described running motor is connected with described drive wheel, described drive wheel and running motor are arranged on the front portion of vehicle frame, described guide wheel is arranged on the rear portion of vehicle frame, also comprise auxiliary caterpillar wheel and driven shaft for being connected with described auxiliary caterpillar wheel, described driven shaft is fixed on described vehicle frame in mode moving up and down.
In above-mentioned front wheel driving ejector half crawler vehicle walking chassis structure, the both sides of described vehicle frame are respectively equipped with a chute, in described chute, are provided with slide block, are provided with the bearing being connected with driven shaft in described slide block, in described chute, be provided with spring, the top of described spring is connected with slide block.
The utility model driver train is preposition, and guide wheel postposition relies on vehicle body deadweight descending in the time of descending, in the time going up a slope, front driving wheel provides propulsive effort, guide wheel postposition, and the application force to crawler belt of guide wheel reduces, stretching device load reduction, consumption of power is little, adopts underslung auxiliary caterpillar wheel simultaneously, increases the earth-grasping force of rear side crawler belt in the time going up a slope, improve grade climbing performance, and the caterpillar wheel that prevents rear side transships undue wear for a long time.
Brief description of the drawings
Fig. 1 is the lateral plan of specific embodiment of the utility model 1;
Fig. 2 is the front elevation of specific embodiment of the utility model 1;
Fig. 3 is that the driven shaft of specific embodiment of the utility model 1 is connected to the schematic diagram on vehicle frame.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the technical solution of the utility model is described in further detail, but does not form any restriction of the present utility model.
Embodiment 1
As shown in Fig. 1~2, a kind of front wheel driving ejector half crawler vehicle walking chassis structure, comprise vehicle frame 1, the both sides of described vehicle frame 1 are provided with drive wheel 3, guide wheel 4, tightening device 5, caterpillar wheel 6, holder chain mechanism 7, described drive wheel 3, guide wheel 4, tightening device 5, caterpillar wheel 6, holder chain mechanism 7 is in transmission connection by crawler belt 2, described tightening device 5 is connected with described guide wheel 4, it is characterized in that, also comprise running motor 8, described running motor 8 is connected with described drive wheel 3, described drive wheel 3 and running motor 8 are arranged on the front portion of vehicle frame 1, described guide wheel 4 is arranged on the rear portion of vehicle frame 1, also comprise auxiliary caterpillar wheel 9 and driven shaft 10 for being connected with described auxiliary caterpillar wheel 9, described driven shaft 10 is fixed on described vehicle frame 1 in mode moving up and down, as shown in Figure 3, the both sides of described vehicle frame 1 are respectively equipped with a chute 11, in described chute 11, be provided with slide block 12, in described slide block 12, be provided with the bearing being connected with driven shaft 10, in described chute 11, be provided with spring 13, the top of described spring 13 is connected with slide block 12.Spring 13 also can adopt hydraulic pressure beam hanger to substitute in the present embodiment, in the time that crawler vehicle is climbed, and oil cylinder oil return, auxiliary caterpillar wheel 9 falls starts working.Holding in the palm in the present embodiment chain mechanism 7 is a trapezoidal framework, also can be chosen as holder sprocket wheel.
In the time of level road walking or descending, the spring of auxiliary caterpillar wheel 9 is not compressed to the height of appointment, and auxiliary caterpillar wheel is in suspension status, in the time going up a slope, tare concentrates on body tail, and spring 13 is compressed to the position of appointment locked, and auxiliary caterpillar wheel 9 is started working, after climbing finishes, spring 13 releases, will assist caterpillar wheel 9 to hang, in the present embodiment, caterpillar wheel 6 is equidistantly arranged, and auxiliary caterpillar wheel 9 is arranged between two adjacent caterpillar wheels 6 of rear vehicle.
In the present embodiment, driver train is preposition, and guide wheel 4 postposition rely on vehicle body deadweight descending in the time of descending, in the time going up a slope, front driving wheel 3 provides propulsive effort, guide wheel 4 postposition, and the application force to crawler belt of guide wheel 4 reduces, tightening device 5 load reductions, consumption of power is little, adopts underslung auxiliary caterpillar wheel 9 simultaneously, increases the earth-grasping force of rear side crawler belt 2 in the time going up a slope, improve grade climbing performance, and prevent the long-term overload undue wear of caterpillar wheel 6 of rear side.The caterpillar machinery of the long-time frequent uphill/downhill of needs that the present embodiment is specially adapted to move in drive.
Above-described is only preferred embodiment of the present utility model, all any amendments of doing within the scope of spirit of the present utility model and principle, is equal to and replaces and improvement etc., within all should being included in protection domain of the present utility model.
