For each household, there are sometimes encounters such as the blockage of the sewage pipeline. In general we will ask a professional team to solve the problem. That magnifies the point of view of the same congestion problem for a community or a street. General owners or managers are invited to clean the septic tanks when the septic tank is blocked. However, the sewer truck does not have the property of dredge pipe. Such a limitation results in the generation of cleaning slush trucks. First, the collection of sewage vehicles and high-pressure cleaning vehicle functions in a new special vehicle for sanitation is called cleaning sewage vehicles, also known as high-pressure cleaning with sewage suction car. The combination of features of these two models is more favored by customers, so it is very popular in the market. In the past, more than a single high-pressure cleaner or sewer truck was sold on the market. However, in the event of a blockage, if the sewer truck is to be cleaned , the blocked pipe part can be opened and the sewer truck can be used. Clean up dirt. Second, the advantages of this model is that it can be used as a multi-purpose vehicle. In addition to high-pressure cleaning and sewage suction vehicles, other dual-environmental models on the market can also be equipped with high-pressure cleaning with sprinkler, high-pressure cleaning belt suction truck, high-pressure cleaning belt lifting platform. . In addition, snow shovels can also be installed to remove snow from roads, install fence cleaning brushes, and clean highways and urban road barriers. It will not be detailed here. Third, the disadvantage is obviously the cleaning of sewage vehicles, although the dual module preparation, but the cleaning function and the suction function can not be used at the same time, only the limitations of a single job does not improve the number of ergonomics. The principle of dual-use vehicles is to use powerful high-pressure water jet technology to clean old stains on the wall and pavement. Wash with high pressure and low flow to achieve the best flushing effect and clear the sewer. V. Cleaning sewage vehicles are widely used in landscaping spraying, sewer sediments, dead mud mud dredge, urban sculpture, glass wall washing, sewage suction, high pressure flushing the road surface. The main function is to clear the blocked areas of the sewers that workers cannot reach. Readers who read through this article can easily understand the functional configuration of cleaning and sewer trucks through the above description.

Basic terminology for transmission: Transmission Box,Wheel Loader Transmission Assy,Transmission Gear Selector,Transmission Oil Radiator Shandong Tianfu International Trade Co.,Ltd. , https://www.tfloaderparts.com
(1) Driving gear and driven gear. The input shaft can be understood as connected to the clutch and rotates under the drive of the engine. The gear fixed on the input shaft rotates accordingly. This gear is called the driving gear and the gear connected to the output shaft is forced to rotate. This gear is called a driven gear.
(2) Transmission ratio i. The ratio of the number of Teeth of the driven gear to the number of teeth of the driving gear is defined as the transmission ratio.
When the relationship between the number of teeth of the driven gear and the number of teeth of the driving gear changes, the transmission ratio i changes. Under the condition of constant engine speed, it will affect the output shaft speed change, that is, the wheel speed change. For a pair of gears that mesh with each other, the number of teeth will not change during use, so its transmission ratio is fixed. If a number of gears with unequal numbers of teeth are installed on the input shaft to mesh with gears with varying numbers of teeth on the output shaft, a set of stepped transmissions with different transmission ratios i can be obtained. The automobile transmission is based on this basic principle to realize the gear shift.
(3) Forward gear, a gear position that enables the car to travel forward. Reverse gear is a gear that can make the car go backwards. In neutral, all gears in the transmission are not in the working position. At this time, after the engine power is input to the input shaft, it is no longer transmitted to the output shaft.
(4) Direct files. The engine power is not transmitted by any gears in the transmission, but directly output through the transmission input shaft and the output shaft directly connected to it as a direct gear. The direct gear ratio is 1.
(5) Overdrive gear. That is, the speed of the output shaft is higher than the gear of the input shaft.
(6) Number of files. Refers to the number of gears that the stepped gear transmission has. Commonly used gear transmissions have four to five gears, and three-speed transmissions are rare. The more gears, the better the car's adaptability to driving conditions and the lower the fuel consumption. However, the more complex the transmission mechanism and the operating mechanism, the more difficult the operation and the higher the cost.
(7) Low-end and high-end. In the gears of the transmission, the gear with the smaller number is called low gear. The smaller the number, the greater the transmission ratio, the greater the traction, and the lower the vehicle speed. For example, the transmission ratio of first gear is the largest in the forward gear, the vehicle speed is the lowest, and the traction is the largest. A gear with a large number is called high-end. The larger the number, the smaller the transmission ratio and the lower the traction, but the higher the speed.
(8) Shift gears. The process of changing the transmission ratio of the transmission is called shifting. The gear shift of the adapter sleeve is integrated with the gear, and the gear ring on the tooth side meshes (or separates) with the adapter sleeve to achieve the transmission ratio change is called the adapter sleeve shift. Synchronizer shifts, use synchronizer to shift gears. Not only is there no impact and noise on the engaging teeth, but the shift time is also short.
(9) Skip gears. During the driving of the automobile, due to the wear and vibration of the coupling teeth, the coupling sleeve and the coupling ring gear are separated and the transmission is in a neutral state.
