All-terrain fire fighting truck chassis with power take-off

Abstract

This utility model discloses an all-terrain fire truck chassis with a power take-off (PTO), comprising an engine and a gearbox. The gearbox output end has a front drive shaft and a rear drive shaft. The rear drive shaft has a rear axle reducer at its rear, and a rear drive shaft is mounted on the rear axle reducer, driving the rear wheels. The front drive shaft has a front reducer at its front, a half-shaft on the front reducer, a PTO on the half-shaft, and a water pump mounted on the PTO, driving the water pump. This utility model provides an all-terrain fire truck chassis with a PTO. The engine outputs power, which is transmitted to the PTO through the gearbox, front drive shaft, front axle clutch, reducer, and half-shaft. The PTO then drives the water pump. Because the water pump directly obtains power from the engine, it has a long operating range, a long spray distance, and good firefighting effect.

Description

Technical Field

[0001] This utility model relates to a fire truck, or more precisely, an all-terrain fire truck chassis with a power take-off device. Background Technology

[0002] All-terrain fire trucks are special fire-fighting vehicles designed specifically for complex terrains. They possess high mobility, strong passability, and multi-functional rescue capabilities, and are widely used in natural disaster relief scenarios such as forest fires, earthquakes, and mudslides. However, existing all-terrain fire trucks rely on battery power for their water pumps, resulting in limited range and poor spraying performance, thus affecting the pump's fire-fighting function. Utility Model Content

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: An all-terrain fire truck chassis with a power take-off (PTO) device is characterized in that the chassis includes an engine and a gearbox, and the output end of the gearbox is provided with a front drive shaft and a rear drive shaft. The rear of the rear drive shaft is provided with a rear axle reducer, and the rear axle reducer is provided with a rear drive shaft, which drives the rear wheels.

[0005] The front drive shaft is equipped with a front reducer, the front reducer is equipped with a half shaft, the half shaft is equipped with a power take-off (PTO), the PTO is equipped with a water pump, and the PTO drives the water pump.

[0006] In a preferred embodiment of this utility model, a front axle clutch is provided between the front drive shaft and the front reducer.

[0007] In a preferred embodiment of this utility model, a rear axle clutch is provided between the rear drive shaft and the rear axle reducer.

[0008] In a preferred embodiment of this utility model, the front drive shaft and the rear drive shaft are coaxially arranged.

[0009] In a preferred embodiment of this utility model, the water pump is connected to the power take-off via screws.

[0010] Compared with the prior art, the present invention has the following beneficial effects: This utility model provides an all-terrain fire truck chassis with a power take-off (PTO). The engine outputs power, which is transmitted to the PTO through the gearbox, front drive shaft, front axle clutch, reducer, and half-shaft. The PTO then drives the water pump. Because the water pump directly obtains power from the engine, it has a long operating range, a long spray distance, and good firefighting effect. Attached Figure Description

[0011] To more clearly illustrate the solutions in this utility model, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are some embodiments of this utility model. For those skilled in the art, other drawings can be obtained from these drawings without creative effort.

Water pump; 10. Rear axle clutch; 11. Rear axle reducer; 12. Rear drive shaft; 13. Rear wheel; 2. Power take-off; 3. Half shaft; 4. Front reducer; 5. Front axle clutch; 6. Front drive shaft; 7. Gearbox; 8. Engine; 9. Rear drive shaft. Detailed Implementation

[0013] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0014] like Figure 1 As shown, the all-terrain fire truck chassis with power take-off includes an engine 8 and a gearbox 7, with a front drive shaft 6 and a rear drive shaft 9 located at the output end of the gearbox 7.

[0015] The rear drive shaft 9 is provided with a rear axle reducer 11, and the rear axle reducer 11 is provided with a rear drive shaft 12, which drives the rear wheel 13.

[0016] The front drive shaft 6 is equipped with a front reducer 4 at the front, a half shaft 3 is provided on the front reducer 4, a power take-off 2 is provided on the half shaft 3, a water pump 1 is provided on the power take-off 2, and the power take-off 2 drives the water pump 1.

[0017] In addition, a front axle clutch 5 is provided between the front drive shaft 6 and the front reducer 4. A rear axle clutch 10 is provided between the rear drive shaft 9 and the rear axle reducer 11.

[0018] It should be noted that the front drive shaft 6 and the rear drive shaft 9 are coaxially arranged.

[0019] In addition, the water pump 1 is connected to the power take-off 2 by screws, thus realizing the detachable structure of the water pump 1.

[0020] The following describes the working method of the all-terrain fire truck chassis with power take-off device.

[0021] Driving mode: The front drive shaft 6 is disconnected from the front reducer 4, and the rear drive shaft 9 is engaged with the rear axle reducer 11 through the rear axle clutch 10. The engine 8 outputs power, which is transmitted to the rear drive shaft 12 through the gearbox 7, the rear drive shaft 9, the rear axle clutch 10, and the rear axle reducer 11. The rear drive shaft 12 drives the rear wheels 13 to work, and the vehicle is in driving mode.

[0022] Water pumping mode: The rear drive shaft 9 is disconnected from the rear axle reducer 11, the front drive shaft 6 is engaged with the front reducer 4 through the front axle clutch 5, the engine 8 outputs power, and the power is transmitted to the power take-off 2 through the gearbox 7, the front drive shaft 6, the front axle clutch 5, the front reducer 4, and the half shaft 3. The power take-off 2 drives the water pump 1 to work, and the vehicle is in the water pumping state.

[0023] It should be noted that the front axle clutch 5 and the rear axle clutch 10 cannot be engaged at the same time.

[0024] Because water pump 1 gets its power directly from engine 8, it has a long endurance, a long spray distance, and a good fire-fighting effect.

[0025] Obviously, the embodiments described above are only some embodiments of this application, and not all embodiments. The accompanying drawings show preferred embodiments of this application, but do not limit the patent scope of this application.
