Description
Technical field
The utility model is related to fire-fighting equipment technical fields, more specifically, are related to a kind of wagon.
Background technology
Wagon belongs to special apparatus, is mainly used for providing the fire hose of rescue for main-battle firefighting truck, and
Water is taken back to take back after rescue and is stored in stand-by state comprising the chassis of wheeled, the power compartment being set on chassis
With storage band compartment, it is provided with placement machine on storage band compartment, is slided above placement machine and is provided with belt-retracting device, in belt spreading machine
Reasonable band device is set below structure, and in fire-fighting and rescue, operating personnel open storage band compartment, take out water band, and water band one end is set
It stores up and is laid with the roads Shui Daiyan in compartment with the walking of wagon in the first operating position (such as fire water supply offer point)
To the second operating position (such as rescue place), hose laying is completed.After rescue, wagon works from first
Position is carried water by components such as placement machine, belt-retracting device and reason band devices to the second operating position (also can be reversed)
The folding and unfolding of sequence returns to be stored in and stores up band compartment, in case next time uses.
Wagon at least normally travel operating mode and operating mode is run at a low speed, under normally travel operating mode, water band fire-fighting
Vehicle normally travel, for example rush towards the operating mode of emergency place in wagon.In the case where running at a low speed operating mode, wagon low speed
Traveling coordinates hose laying or water band to recycle, and under such operating mode, needs power drive placement machine, belt-retracting device, reason band dress
The actions such as set.
At present there are mainly two types of upper dress (component being arranged on chassis) power taking modes of wagon, one is engines
Power taking, another is transmission shaft off-axis power taking.Engine torque extraction is as shown in Figure 1, on the one hand, the power output end of engine passes through
Gearbox, chassis transmission shaft output power to drive axle, driving wagon traveling；On the other hand, the power taking of engine
The output end of input terminal of the output end through transmission axis connection transfer case, transfer case connects the works such as oil pump (constant displacement pump), flushing water pump
Make device, meanwhile, be provided in transfer case clutch, transmission gear, it can be achieved that the individual operation of oil pump, flushing water pump it is independent
It is operated while operating and oil pump and flushing water pump.Off-axis power taking mode is as in Figure 2-4, and principle is that engine connection becomes
Fast case, gearbox connect the first input end of transfer case, output end connection oil pump, the rear chassis of transfer case through front chassis transmission shaft
Second input terminal of transmission shaft, transfer case is also associated with motor, and the oil outlet of at least one oil pump is connected to the oil inlet of motor.
Transfer case is there are three types of operating mode, as shown in Fig. 2, the input terminal of the first input end and rear chassis transmission shaft of transfer case under the first operating mode
Engagement makes the power of the engine transfer case after through pass to drive axle, driving wagon normally travel.Under second operating mode such as
Shown in Fig. 3, the first input end of transfer case is engaged with the input terminal of rear chassis transmission shaft, makes the power of the engine transfer case after
Drive axle is passed to, wagon normally travel is driven, meanwhile, the first input end of transfer case also drives with the input terminal of oil pump
Dynamic connection, driving oil pump provide power for other equipments on wagon chassis.Under third operating mode as shown in figure 4,
The input terminal of the first input end of transfer case and oil pump is drivingly connected, and the first input end of transfer case is defeated with rear chassis transmission shaft

Case occupied space is big, and arrangement difficulty is big, and influences storage band ability of the water with fire-fighting.Simultaneously as wagon is received in water band
The stage to be put, low speed, smooth-ride are needed, driving dynamics demand is smaller, and on belt-retracting device, reason band device and placement machine etc.
It fills equipment power and needs big, and during rushing towards emergency place, oil pump (constant displacement pump) and do not need work, thus,
Pressure fuel pump, flow change with the variation of speed, the hydraulic power source that can not stablize to offers such as belt-retracting devices, it is difficult to control
Wagon low speed smooth-ride.In addition, clutch in transfer case needs often action, be easy to happen failure, repair at
This height.
And for the mode of off-axis power taking, it is still provided with transfer case, meanwhile, transfer case needs to be arranged in wagon
The middle part on chassis, fluid pressure line is more, longer, and pipeline is complicated, of high cost, and transfer case occupied space is big, and arrangement difficulty is big, again
Influence storage band ability of the water with fire-fighting.Meanwhile there is also pressure fuel pump, flows to change with the variation of speed, can not give and receive
The hydraulic power source that the offers such as tape feeding device are stablized, it is also difficult to the problem of controlling wagon low speed smooth-ride.
