Description
Technical field
The utility model is mainly concerned with cleaning Vehicle field, road surface, refers in particular to a kind of cleaning Vehicle high and low pressure water pump transmission device.
Background technique
At present the high and low pressure water pump transmission device of state, inside and outside cleaning Vehicle generally has following two kinds of structural types: a kind of be high-pressure water pump by assistant engine transmission mechanically, low-pressure pump is used the machinery type transmission by the power taking of cleaning Vehicle engine in situ; Another kind is that the high and low pressure water pump is by engine in situ hydraulic-pressure pump power taking, by the oil hydraulic motor transmission.In these two kinds of transmission devices, low-pressure pump is from cleaning Vehicle engine in situ power taking transmission, the influence of pump rotary speed (flow) suspension chassis engine speed.Nowadays one of critical function of cleaning Vehicle low-pressure pump is the pouring that is used for road both sides green belt, and when this operation, often needs the ultralow speed of a motor vehicle and bigger water flow.But existing low-pressure pump transmission device because the engine in situ rotating speed descends, also descends pump rotary speed under the ultralow speed of a motor vehicle thereupon, causes pump capacity to significantly reduce, and has a strong impact on the pouring effect.
The model utility content
The technical problems to be solved in the utility model just is: at the technical problem of prior art existence, the utility model provides a kind of cleaning Vehicle that can make when the ultralow speed of a motor vehicle is worked, can not have influence on the rotating speed and the water flow of low-pressure pump, can satisfy the cleaning Vehicle high and low pressure water pump transmission device that greening irrigation water flow requires.
In order to solve the problems of the technologies described above, the solution that the utility model proposes is: a kind of cleaning Vehicle high and low pressure water pump transmission device, it comprises assistant engine, high-pressure water pump and low-pressure pump, it is characterized in that: described assistant engine links to each other with high-pressure water pump and low-pressure pump by driving mechanism.
Described driving mechanism is a transfer case, this transfer case comprises input shaft, driving gear, driven gear, first output shaft and second output shaft, input shaft links to each other with the transmission shaft of assistant engine, first output shaft links to each other with input shaft, and the driving gear that is installed on first output shaft is meshed with driven gear on being installed on second output shaft; Described first output shaft links to each other with low-pressure pump by hydraulic-pressure pump, pipe-line system, oil hydraulic motor and the coupling that links to each other successively, and second output shaft links to each other with high-pressure water pump by coupling.
The engagement cover of combination can handled or disengagement high-pressure water pump is arranged in the described transfer case, and this engagement is sheathed on second output shaft.
Compared with prior art, advantage of the present utility model is: high-pressure water pump of the present utility model links to each other with assistant engine by driving mechanism with low-pressure pump, all obtain power and carry out operation from assistant engine, like this, just can not be because of obtaining power and the operation speed of machine of cleaning Vehicle is had an immense impact on to high and low pressure pump rotary speed and water flow from engine in situ, therefore the utility model can satisfy under ultralow operation speed of machine, and cleaning and greening irrigation are to the needs of pump capacity.

Embodiment
Below with reference to accompanying drawing the utility model is described in further details.
As Fig. 1, Fig. 2 and shown in Figure 3, cleaning Vehicle high and low pressure water pump transmission device of the present utility model comprises assistant engine 2, high-pressure water pump 6 and low-pressure pump 7, and this assistant engine 2 links to each other with high-pressure water pump 6 and low-pressure pump 7 by driving mechanism.The utility model has changed low-pressure pump 7 in the past obtains power from the motor on cleaning Vehicle chassis 1 way, so just solved when the low speed of a motor vehicle of cleaning Vehicle is walked, the slow-speed of revolution of engine in situ has influence on the problem of the need of work of high-pressure water pump 6 and low-pressure pump 7, therefore the utility model can satisfy under ultralow operation speed of machine, and cleaning and greening irrigation are to the needs of pump capacity.In the present embodiment, driving mechanism adopts transfer case 4, this transfer case 4 comprises input shaft 12, driving gear 14, driven gear 16, first output shaft 15 and second output shaft 18, wherein input shaft 12, first output shaft 15 and second output shaft 18 all are to be fixed in the transfer case 4 by bearing 13, input shaft 12 links to each other with the transmission shaft 3 of assistant engine 2, first output shaft 15 links to each other with input shaft 12, and the driving gear 14 that is installed on first output shaft 15 is meshed with driven gear 16 on being installed on second output shaft 18; The hydraulic-pressure pump 11 of first output shaft 15 by linking to each other successively, pipe-line system 10, oil hydraulic motor 9 links to each other with low-pressure pump 7 with first coupling 8, second output shaft 18 links to each other with high-pressure water pump 6 by second coupling 5, and in transfer case 4, also be provided with and handle combination or throw off high-pressure water pump transmission engage a gear mechanism, driven gear 16 is a free gear, be connected on second output shaft 18 by spline, engagement cover 17 links to each other with second output shaft 18 by spline, when the needs engage a gear, to mesh cover 17 and slide into driven gear 16 places, realize being connected by spline, thereby make driven gear 16 enough be with second output shaft 18 to rotate, perhaps directly make driven gear 16 move to second output shaft, 18 places and cooperate with it.
Working principle: when cleaning Vehicle high and low pressure water pump transmission device of the present utility model is worked, assistant engine 2 is by the input shaft 12 of transmission shaft 3 transmission transfer cases 4, logical again first output shaft, 15 transmission fluid oil-pressing pumps 11 drive oil hydraulic motor 9, by 7 work of coupling 8 transmission low-pressure pumps; Input shaft 12 is by driven gear 16, engagement cover 17, second output shaft 18 and the coupling 5 of driving gear 14 transmissions and its engagement, 6 work of transmission high-pressure water pump.Handle engagement cover 17 can in conjunction with or throw off high-pressure water pump 6 transmissions.By above statement as can be known, the rotating speed of the utility model cleaning Vehicle high and low pressure water pump transmission device is all irrelevant with the chassis speed of operation, need only during work assistant engine 2 rotating speeds are controlled well, just can guarantee high-pressure water pump 6 and low-pressure pump 7 stable rotating speed and flow, satisfy the requirement of cleaning and greening irrigation.
