Description

A water propulsion transmission device for a light all-terrain vehicle

technical field

The utility model relates to a water propulsion transmission device for a light all-terrain vehicle, in particular to a water propulsion transmission device for an 8x8 light all-terrain vehicle capable of maneuvering and flexibly driving in various terrains such as mountains, swamps, rivers, and deserts.

Background technique

At present, the water propulsion system of the known light all-terrain vehicle is either propulsed by the rotation of the wheels in the water, which has the disadvantages of low propulsion speed and high fuel consumption; or a high-power-density blade-type water-jet propulsion system for amphibious armor , its disadvantages are complex structure, poor reliability and high development cost; or it is propelled by a single propeller suspended at the rear of the car body, the disadvantage is that the power unit is independent, takes up a large space, and has limited fuel reserves. These power transmission methods, as well as the propulsion system, all have serious shortcomings and deficiencies, which have caused great troubles for the arrangement of the car body and the improvement of the performance of the whole car.

Contents of the invention

The purpose of the utility model is to provide a water propulsion transmission device of a light all-terrain vehicle that perfectly combines the driving device of the water and land and shares the same steering system, so as to overcome the shortcomings of the existing light all-terrain vehicle water propulsion system.

The purpose of this utility model can be achieved through the following technical measures: that is: the water propulsion transmission device of this light all-terrain vehicle, its engine, gearbox, transmission shaft, and steering transmission box are connected in sequence, and the steering transmission box passes through the transmission system on the one hand. It is connected with the wheels, and on the other hand, the two output shafts of the steering transmission box are connected with the left and right water push transfer cases at the same time, and the left and right water push transfer cases are respectively connected with the left and right propellers. The power source of the water propulsion system comes directly from the steering transmission box, and the power on and off is controlled by switching the motor. When traveling on water, the left and right propellers rotate clockwise and counterclockwise at the same speed to achieve straight driving; when turning, the two output shafts of the steering transmission box can be controlled to achieve a differential speed, so that the left and right propellers can rotate at the same speed. Higher speed and lower speed, easy to realize steering on water; when the left and right two propellers rotate in the same direction, in-situ steering can be realized; when reversing, the transmission is shifted to reverse gear, and the left and right propellers rotate counterclockwise and clockwise respectively to realize reversing .

Compared with the prior art, the utility model perfectly combines the water and land driving devices and shares the same steering system, which fully saves the space of the car body and the development of the whole vehicle under the premise of ensuring high-speed and reliable driving on water, easy steering and reversing. The manufacturing cost overcomes the low propulsion speed and high fuel consumption brought by the rotating propulsion of the wheels in the water in the prior art, or the complex and reliable structure brought about by the high power density blade water jet propulsion system using amphibious armor. The performance is poor and the development cost is high, or the propulsion by a single propeller suspended at the rear of the car body is independent of the power device and takes up a lot of space.

Detailed ways

Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the water propulsion transmission device of a light-duty all-terrain vehicle of the present invention, its engine 1 is connected with the transmission 5, transmission shaft, and steering transmission box 7 in sequence, and the steering transmission box 7 passes through The chain is in turn connected with the pinion shaft of the wheel reduction gearbox. At the same time, the engine 1 transmits power to the hydraulic pump 4 through the belt pulley system 2 and the hydraulic pump drive shaft 3. There is an oil pipe 6 between the hydraulic pump 4 and the hydraulic motor 9. The output shaft of the hydraulic motor 9 is connected to the input shaft 20 of the steering combiner box 8. , steering combiner box 8 and steering transmission box 7 are connected by chains and sprockets. Three gear shafts [see Figure 3] are arranged in the housing of the steering combiner box 8, and the three gear shafts mesh with each other, wherein the input shaft 20 is connected with the hydraulic motor 9, and the two output shafts 21, 22 are connected with the steering transmission box 7 through chains.

The steering transmission box 7 receives the power from the gearbox 5, and outputs it to the left and right water push transfer boxes 11 respectively. When the power switching motor 10 is turned on, it pushes the gear shift connector 15 to slide outward on the gear 14, and is connected with The gear 16 meshes and runs, and the gear 16 and the flange 17 are in a tight fit relationship, then the flange 17 starts to run, and drives the spiral bevel gear 18, the spiral bevel gear 19, and the propellers 12 and 13 to run. At this time, the left and right propellers are respectively To turn right and left at the same speed, so as to realize straight travel on the water surface; when steering is required, the hydraulic steering device receives the power of the engine 1, starts running and provides a certain hydraulic signal to the steering combiner box 8, and the steering combiner box 8 is the steering drive The box 7 outputs two sets of power in different rotation directions, so that the two output shafts of the steering transmission box 7 accelerate and decelerate at the same time, that is, to realize the differential speed effect, and the steering is realized by the speed difference of the two propellers; when turning in situ, the speed change Box 5 is in neutral, and the steering transmission box only receives the power from the steering combiner box, and its two output shafts rotate in the opposite direction under the action of the steering combiner box. At this time, the left and right propellers rotate in the same direction, so as to realize the in-situ steering in still water ; When the transmission 5 is in the reverse gear, it can realize reversing on water. When the power switching motor 10 was closed, the propeller power was cut off and stopped running.
