Problems solved by technology

In this way, two engines are installed on one washing and sweeping vehicle, and the two engines are running during the operation process. Among them, the chassis engine with higher power runs at low speed and low power for a long time, and the power utilization rate is very low. The energy consumption efficiency of the machine is lower, and the installed power is wasted a lot
On the other hand, the fuel consumption, exhaust emissions and noise pollution caused by the simultaneous operation of two engines will inevitably increase, which not only increases the cost of use of such equipment, but also causes more serious damage to the human living environment. The development of a single engine washing machine Car sweeping has become the consensus and direction of joint efforts of such equipment manufacturers

Embodiment 1

[0036] Embodiment 1, under the cleaning condition of the cleaning vehicle, the principle of the power transmission of the pure hydraulic H1 forward gear of the present invention is as follows figure 2 Shown: in the cleaning condition, the cleaning speed is 3-10km / h, the hydraulic oil pump 11, the blower fan 38 and the high-pressure water pump 1 work at the same time, the low-pressure water pump 10 does not work, and the hydraulic oil pump 11 can be the sweeper on the cleaning vehicle. The disc motor provides power, and the sweeping motor drives the sweeping disc to sweep the road surface garbage into the suction nozzle of the fan 38. At the same time, the high-pressure water pump 1 performs high-pressure washing on the road surface. Finally, the fan 38 sucks the sewage formed by washing into the sewage tank to complete the cleaning operation. process. This process adopts pure hydraulic drive vehicle running gear, and the power transmission process of the engine purely mechani...

Embodiment 2

[0037] Embodiment 2. Under the dry sweeping working condition of the washing and sweeping vehicle, the principle of the power transmission of the pure hydraulic H2 forward gear of the present invention is as follows image 3 Shown: in the dry sweeping condition, the driving speed is 5-20km / h, the road dust is less, only the hydraulic oil pump 11 and the fan 38 work at the same time, the high-pressure water pump 1 and the low-pressure water pump 10 do not work, the hydraulic oil pump 11 can be The sweeping motor provides power, and the motor drives the sweeping disk to sweep the road surface garbage into the nozzle of the fan 38. The low-pressure water pump 10 does not clean the road surface and reduce dust. The fan 38 directly sucks the garbage into the sewage tank to complete the cleaning process. This process also uses The power transmission process of the purely hydraulically driven vehicle and the purely mechanically driven cleaning assembly of the engine is as follows: the...

Embodiment 3

[0038] Embodiment 3. Under the wet sweeping working condition of the cleaning vehicle, the principle of the power transmission of the pure hydraulic H1 forward gear of the present invention is as follows Figure 4 Shown: In the wet sweeping condition, the driving speed is 5-20km / h, and the road surface is dusty, the hydraulic oil pump 11, the fan 38, and the low-pressure water pump 10 are required to work at the same time, the high-pressure water pump 1 does not work, and the hydraulic oil pump 11 can be used for sweeping The disk motor provides power, and the motor drives the sweeping disk to sweep the road surface garbage into the suction nozzle of the fan 38. The fan 38 directly sucks the garbage into the sewage tank, and then the low-pressure water pump 10 cleans and reduces dust on the road surface to complete the wet sweeping process. This process is also the same The power transmission process of the purely hydraulically driven vehicle and the engine purely mechanically ...

Abstract

The invention relates to the field of environmental sanitation sweepers, in particular to an integrated hydro-mechanical transmission device for single-engine washing and sweeping vehicle. The integrated hydro-mechanical transmission device for single-engine washing and sweeping vehicle comprises a shell, wherein a main input shaft connected with an engine, a main output shaft connected with a washing and sweeping vehicle driving wheel, and multiple auxiliary output shafts connected with sweeping components on the washing and sweeping vehicle are rotatably arranged on the shell; a variable transmission assembly is arranged among the main input shaft, the main output shaft and the multiple auxiliary output shafts; and an independent transmission assembly is arranged between the main input shaft and the multiple auxiliary output shafts. The single-engine integrated hydro-mechanical transmission device for the washing and sweeping vehicle provided by the invention is high in power utilization ratio, low in oil consumption pollution, and suitable for the development direction of the sweepers in the future.

Description

technical field [0001] The invention relates to the field of sanitation and sweeping vehicles, in particular to an integrated hydraulic-mechanical transmission device for a single-engine cleaning and sweeping vehicle. Background technique [0002] With the improvement of the level of urban environmental governance, the number of special vehicles used for cleaning and cleaning urban streets, squares, and highways is increasing. The installed power of some cleaning and sweeping vehicles is increasing. These medium and large cleaning and sweeping vehicles are based on the chassis of General Motors. During the operation, the requirements for the speed of the chassis are not high. Work on city roads. However, the working devices of this type of special vehicles need high-power drive, and the rotating speed of its main working devices is also very high. [0003] At present, the vast majority of similar equipment at home and abroad use a dedicated auxiliary engine as the power so...
