Description
Technical Field
[0001] The utility model relates to an amphibious vehicle, in particular to an all-round amphibious transport vehicle. Background Art
[0002] In recent years, amphibious vehicles have attracted much attention because of their good practical value during use. However, due to the special nature of amphibious vehicles, the presence of wheels will generate greater resistance when sailing in the water, which will undoubtedly increase unnecessary energy consumption, and is not conducive to water control and is not flexible enough. For this reason, relevant personnel have proposed an improvement measure, which is to store the wheels when sailing in the water (mostly lateral designs, due to transmission structure limitations, the movement displacement and amplitude are limited). But even so, there is still draft space after the wheels are stored, and the previous shortcomings still exist. Utility Model Content
[0003] The utility model aims to solve the problem of large water resistance of existing large-scale amphibious transport vehicles, reduce energy consumption and increase transportation capacity by solving the problem of large water resistance of existing large-scale amphibious transport vehicles.
[0004] The technical solution adopted by this utility model:
[0005] The utility model is an all-terrain amphibious vehicle, and the lower sides and bottom shell of the vehicle are watertight bodies, and its drive control system includes a wheel drive system and a propeller drive system. The difference from the prior art is that a front wheel accommodating cavity is provided at the front of the vehicle chassis, and a rear wheel accommodating cavity is provided at the rear of the vehicle chassis, the wheels are installed in a large beam frame and are installed at the lower end of the vehicle chassis through a lifting and storage mechanism; and a cover plate is provided on the lower shell of the vehicle body to match the wheel accommodating cavity or the gap for the wheel to enter and exit, and a drive and control device is provided on the vehicle body in coordination with the cover plate.
[0006] The all-terrain amphibious vehicle has a wheel drive system with a transfer case in the gearbox. The vehicle's engine system, gearbox and transfer case are located in the middle of the watertight body. The front wheel transfer output of the transfer case is connected to the front wheel drive shaft via the front axle, and the rear wheel transfer output of the transfer case is connected to the rear wheel drive shaft via the rear axle. To facilitate wheel storage, universal joints are provided in the middle of the front axle and the rear axle.
[0007] The all-terrain amphibious vehicle has cover plates arranged on the open sides of the front axle and front wheel and the rear axle and rear wheel accommodating space / accommodating cavity. The cover plates are located in tracks arranged on both sides of the wheel accommodating cavity in the lower shell of the vehicle, and a driving and control mechanism for controlling the movement of the cover plates is connected to the cover plates.
[0008] In the all-terrain amphibious vehicle, the cover plate and the rear axle and rear wheel accommodating cavity are tightly connected by a water-sealed structure; when the cover plate and the rear axle and rear wheel accommodating cavity are non-water-sealed structures, a drainage device is provided in the accommodating cavity.
[0009] The all-terrain amphibious vehicle has gaps for wheels to enter and exit on the outer bottom plates of the front axle and front wheels and the rear axle and rear wheel accommodating cavities, a cover plate is provided in cooperation with the gaps for wheels to enter and exit, and a cover plate movement track is provided in cooperation with the cover plate, and a driving and control mechanism for controlling the movement of the cover plate is connected to the cover plate.

[0011] The wheel lifting and storage mechanism and the cover driving and control device of the all-terrain amphibious vehicle are driven by hydraulic cylinders or screws.
[0012] Beneficial effects of the utility model:
[0013] 1. The utility model of the all-round amphibious vehicle solves the problem of large water resistance of existing large amphibious transport vehicles. A front wheel accommodating cavity is provided at the front of the vehicle chassis, and a rear wheel accommodating cavity is provided at the rear of the vehicle chassis. When sailing in water, the wheels are stored inside the vehicle through a lifting and storing mechanism and closed with a cover plate; the entire vehicle becomes a ship-shaped body, and can sail in the water as a ship with the propeller and rudder at the tail. The water resistance of the amphibious transport vehicle is reduced.
[0014] 2. The utility model of the all-round amphibious vehicle has a larger lifting space and a simpler and more practical cost advantage compared to the rollover wheel storage mechanism. The wheels (including the front wheels and rear wheels and their transmission, brake and other auxiliary facilities) are installed in a large beam frame, and the wheels are stored when sailing on the water through a vertical lifting mechanism. After storage, the lower shell of the vehicle body is closed with a cover plate, so that the entire vehicle becomes a ship-shaped body, which can provide greater buoyancy. For a vehicle with a front axle and rear axle accommodating space of about 2-3㎡, it can increase the displacement by 2-2.5 tons and the buoyancy by 20,000 Newtons. It can save energy consumption when driving in water, reduce navigation costs, and increase transportation capacity.
[0015] 3. The utility model of the all-round amphibious vehicle adopts a transfer case to connect the front axle and the rear axle, sets a universal joint in the middle, and adopts a hydraulic rod or a screw to control the lifting and lowering. The structure is simple and easy to implement. After storage, the lower shell of the vehicle body is closed by a cover plate, so that the whole vehicle becomes a boat-shaped body, which increases the flexibility of driving in water.

[0021] In order to make the technical concept and advantages of the utility model creation to achieve its utility model purpose more clear, the technical solution of the utility model is further described in detail below in conjunction with the accompanying drawings. It should be understood that the following embodiments are only used to explain and illustrate the preferred implementation of the utility model and should not constitute a limitation on the scope of protection of the utility model patent claim. Example
[0022] See also Figure 1 , Figure 2 , Figure 4 The utility model is an all-terrain amphibious vehicle. The lower sides and bottom shell of the vehicle are watertight bodies. Its drive control system includes a wheel drive system and a propeller drive system. A front wheel accommodating cavity 1 is provided at the front of the vehicle chassis, and a rear wheel accommodating cavity 2 is provided at the rear of the vehicle chassis. The wheels (including the front wheels and the rear wheels and their transmission, braking, shock absorption and other auxiliary facilities) are installed in a beam frame (including a front wheel beam frame 3 and a rear wheel beam frame 4), and are installed at the lower part / lower end of the vehicle chassis 6 through a lifting and storing mechanism 5; and a cover plate (including a front cover plate 7 and a rear cover plate 8) is provided on the lower shell of the vehicle body to match the wheel accommodating cavity or the gap for the wheel to enter and exit, and a drive and control device is provided in cooperation with the cover plate to close the lower shell of the vehicle body after the wheels are stored.
[0023] The all-terrain amphibious vehicle has a wheel drive system with a transfer case in the gearbox. The vehicle's engine system, gearbox and transfer case are located in the middle of the watertight body (between the front axle and rear axle accommodating space). The front wheel transfer output of the transfer case is connected to the front wheel drive shaft via the front axle, and the rear wheel transfer output of the transfer case is connected to the rear wheel drive shaft via the rear axle. To facilitate wheel storage, universal joints are provided in the middle of the front axle and the rear axle.
[0024] Considering the center of gravity position when sailing on water, the engine system is arranged under the floor between the front bridge and the middle bridge, which ensures the center of gravity position without occupying the passenger position.
[0025] The utility model is a full-range amphibious vehicle, the whole vehicle is equivalent to having two independent front and rear accommodation spaces, the front axle is integral, the rear axle is also integral, and the wheels can move up and down in the wheel accommodation cavity (angular displacement, the front drive shaft and the rear drive shaft are equivalent to having an inclined accommodation cavity connected to the front and rear axle accommodation spaces). The rear part of the front wheel accommodation space is connected to the transfer case / transfer case front coupling through an oil seal, etc., and the front part of the rear wheel accommodation space is connected to the transfer case / transfer case rear coupling through an oil seal, etc. A universal joint is set in the middle of the front and rear axles, which acts as a pivot when the wheels are lifted or lowered.
[0026] The utility model has a vehicle bridge (connecting the wheel ends) and wheels that can move up and down as a whole. When the wheels are sailing on water, they can be stored inside the vehicle body, and then the gap on the vehicle bottom plate / lower shell body that accommodates the wheels or the entire vehicle accommodating cavity is covered by a movable cover. In this way, the entire vehicle becomes a ship-shaped vehicle body, and then the propeller 9 and the rudder 10 at the tail can be used to sail on water. The problem of large resistance and slow speed of large amphibious transport vehicles on water is solved.
[0027] Figure 3 This is a schematic diagram of the propeller system layout. Figure 2 , Figure 3 The middle bid number 11 is to strengthen the body outer wall.
[0028] For a four-wheel or six-wheel amphibious vehicle, the front and rear axles have a space of about 2-3 square meters (500 mm wide and 1100 mm long), which can increase the displacement by 2-2.5 tons in the water and increase the buoyancy by about 20,000 Newtons, thus providing greater buoyancy, saving fuel resources, reducing navigation costs, and increasing transportation capacity. Example
[0029] See also Figure 4 , Figure 5The all-terrain amphibious vehicle of this embodiment is different from that of Embodiment 1 in that cover plates are arranged on the open sides of the front axle and front wheel and the rear axle and rear wheel accommodating cavities, the cover plates are located in tracks arranged on both sides of the wheel accommodating cavities of the lower shell of the vehicle, and a driving and control mechanism 12 for controlling the movement of the cover plates is connected to the cover plates.
[0030] Figure 5 The middle reference numeral 13 is a track plate, in which the cover plate slides under the action of the driving mechanism.
[0031] The cover plate is matched with the front wheel and rear wheel accommodating cavities and is designed to be a water-tight structure. When the cover plate and the front wheel and rear wheel accommodating cavities are non-water-tight structures, it is possible to consider providing a drainage device in the accommodating cavity so as to automatically drain the accumulated water that has seeped in therein periodically or according to the water level therein. Example
[0032] See also Figure 4 , Figure 5 The global amphibious vehicle of this embodiment is different from Embodiment 1 and Embodiment 2 in that: exist Gaps for wheels to enter and exit are provided on the outer bottom plates of the front axle and front wheels as well as the rear axle and rear wheel accommodating cavities. A cover plate is provided in cooperation with the gaps for wheels to enter and exit, and a cover plate movement track is provided in cooperation with the cover plate. A driving and control mechanism 12 for controlling the movement of the cover plate is connected to the cover plate.
[0033] The cover plate and the gaps for the front and rear wheels to enter and exit can be closed and connected by a water seal structure; when the cover plate and the gaps for the front and rear wheels to enter and exit are closed by a non-water seal structure, a drainage device is provided in the accommodating cavity.
[0034] The cover plate of the all-terrain amphibious vehicle can be arranged on the inner side or the outer side of the lower shell of the vehicle. The preferred solution is to design it on the inner side wall of the lower shell of the vehicle, so that the lower shell of the vehicle is a smooth and complete plane when viewed from the outside. In the case where the cover plate cannot be completely closed, a drainage device is used to extract the water that has infiltrated the wheel receiving cavity. An automatic water level control system can be used to automatically start a drainage pump to drain water when the wheel receiving cavity reaches a certain liquid level. This is not difficult for those skilled in the art.
[0035] In the utility model of the all-round amphibious vehicle, the wheel lifting and storage mechanism and the cover driving and control device can be driven by a hydraulic cylinder or a lead screw, which is also easy to implement for those skilled in the art.
[0036] The utility model is an all-terrain amphibious vehicle, a front wheel accommodating cavity is provided at the front part of the vehicle chassis, and a rear wheel accommodating cavity is provided at the rear part of the vehicle chassis. When sailing in water, the wheels are stored in the vehicle through a lifting and storing mechanism and are closed with a cover plate; the whole vehicle becomes a ship-shaped body, and sails in water with the propeller and rudder at the rear, thereby reducing the water driving resistance of the amphibious transport vehicle and solving the problem of large water driving resistance of existing large amphibious transport vehicles.
[0037] For the all-terrain amphibious vehicle of the utility model, if it is sailing at a short distance and at a low speed, the wheels do not need to be retracted into the vehicle. When sailing on water for a long distance, the wheels are retracted into the vehicle. Within 3 minutes after entering the water, the drive shaft system is in a state of being soaked in water, but referring to the 900mm wading capacity of the 245 model, the impact on the drive shaft is not significant. During normal navigation, since the wheel accommodating cavity is closed, a drainage pump is used to discharge the accumulated water in the wheel accommodating space of the axle when necessary. Under this working condition, the drive shaft is out of the water environment, avoiding the adverse effects of entanglement, muddy water, and collision on the drive shaft. Overall, it has little impact on the service life of the drive shaft.
[0038] The above description is only a preferred embodiment of the utility model and does not constitute a limitation of the utility model. Under the guidance of the prior art, those skilled in the art can make other modifications to the implementation of the utility model without creative work. Any modification made within the spirit and principle of the utility model or simple replacement or equivalent replacement using conventional technical means in the field shall be included in the protection scope of the utility model.
