Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to polar vehicles. Background Technology

[0002] Polar vehicles are specifically designed for polar environments and can travel on various terrains such as snow, deserts, mountains, and mudflats. They possess strong off-road capabilities and adaptability, maintaining stable and reliable operation even in extreme weather conditions. The design and manufacture of polar vehicles must take into account many unique factors, such as variations in polar temperature and air pressure, and the lack of infrastructure and navigational markers. Therefore, polar vehicles require a high level of technical expertise and professionalism.

[0003] Previous patent CN105620566B disclosed a tracked transport vehicle for river network mudslides, which includes a chassis, drive wheels, guide wheels, road wheels, and tracks. The guide wheels and drive wheels are located on the front and rear sides of the chassis, respectively, and the road wheels are located between the drive wheels and guide wheels. The road wheels are mounted on the chassis using a torsion bar spring independent suspension. Because the road wheels are only mounted using a torsion bar spring independent suspension, when the transport vehicle travels on rugged roads such as mountains, the torsion bar spring independent suspension cannot provide stable support for the chassis, thus causing significant pitching and vibration of the chassis, which is detrimental to the stability of the vehicle.

[0004] Therefore, polar vehicles are urgently needed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a polar vehicle to solve the problem in related technologies where the road wheels are only installed with torsion bar spring independent suspension. When the transport vehicle is traveling on rugged roads such as mountains, the torsion bar spring independent suspension cannot provide stable support for the chassis, resulting in large pitch and vibration of the chassis, which is detrimental to the stability of the vehicle.

[0006] This utility model provides a polar vehicle, which includes:

[0007] Chassis;

[0008] The system includes two tracked traveling mechanisms, each positioned on one side of the chassis along a first direction. Each tracked traveling mechanism comprises a drive wheel, an idler wheel, a track, two shock absorbers, multiple road wheels, and multiple torsion bar spring-type independent suspensions. The drive wheel and the idler wheel are spaced apart on the chassis along a second direction. The multiple road wheels are connected to the chassis one-to-one via multiple torsion bar spring-type independent suspensions and are located between the drive wheel and the idler wheel. One end of each shock absorber is hinged to the chassis, and the other end is hinged to a road wheel near either the drive wheel or the idler wheel. The shock absorber is positioned along a third direction. The track surrounds the drive wheel, the idler wheel, and the multiple road wheels.

[0010] As a preferred technical solution for polar vehicles, the outer peripheral surfaces of the load-bearing wheels and the idler wheels are provided with an elastic rubber layer.

[0011] As a preferred technical solution for the polar vehicle, the tracked walking mechanism further includes a track adjuster. The track adjuster includes a lead screw, a sleeve, a nut, and a torsion bar spring. The nut is disposed at one end of the sleeve and rotates around the axis of the sleeve. One end of the lead screw is inserted into the sleeve from the other end and screwed to the nut. The idler wheel is disposed on the sleeve. The other end of the lead screw is pivotally connected to the chassis. One end of the torsion bar spring is fixedly connected to the other end of the lead screw, and the other end of the torsion bar spring is fixedly connected to the chassis.

[0012] As a preferred technical solution for the polar vehicle, it also includes an electric drive mechanism, which includes a controller, a cooling assembly and two motors, the two motors being respectively connected to the two drive wheels;

[0013] The cooling assembly includes a water pump, a radiator, and a fan. The controller and the two motors are each equipped with a water-cooled radiator. The radiator, the water pump, the controller's water-cooled radiator, and the two motors' water-cooled radiators are connected in series. The fan is used to dissipate heat from the radiator.

[0014] As a preferred technical solution for the polar vehicle, the cooling assembly also includes a water tank, the outlet of which is connected to a pipeline between the radiator and the water pump, and the exhaust port of the radiator is connected to the air inlet of the water tank.

[0015] As a preferred technical solution for the polar vehicle, it also includes a vehicle shell, which is fixed on the chassis, and the surface of the vehicle shell along the third direction is a plane.

[0016] As a preferred technical solution for polar vehicles, the vehicle body is provided with an installation cavity;

[0017] It also includes a power battery mechanism and an electric drive mechanism, which are spaced apart at both ends of the mounting cavity along the second direction.

[0018] As a preferred technical solution for the polar vehicle, a heating mechanism is also included. The heating mechanism includes an oil tank, an igniter, a burner, a vaporization screen, a combustion-supporting impeller, an oil pump, a heat exchanger, and an exhaust fan. The burner is provided with a combustion chamber and an air intake chamber communicating with the combustion chamber. The vaporization screen is located in the combustion chamber. The oil tank, the oil pump, and the vaporization screen are connected in sequence. The combustion-supporting impeller is used to send combustion-supporting gas through the air intake chamber to the combustion chamber. The igniter is located in the combustion chamber and is used to ignite the oil and gas in the combustion chamber. The heat exchanger is located in the combustion chamber. The air inlet and air outlet of the heat exchanger are respectively connected to the mounting cavity. The exhaust fan is used to send cold air from the mounting cavity into the air inlet.

[0020] The beneficial effects of this utility model are as follows:

[0021] This utility model provides a polar vehicle, which includes a chassis and a tracked running mechanism. Two tracked running mechanisms are provided, each positioned on one side of the chassis along a first direction. Each tracked running mechanism includes a drive wheel, an idler wheel, a track, two shock absorbers, multiple road wheels, and multiple torsion bar spring-type independent suspensions. The drive wheel and idler wheel are spaced apart on the chassis along a second direction. The multiple road wheels are connected to the chassis via multiple torsion bar spring-type independent suspensions and are located between the drive wheel and the idler wheel. One end of each shock absorber is hinged to the chassis, and the other end is hinged to a road wheel near either the drive wheel or the idler wheel. The shock absorber is positioned along a third direction. The track surrounds the drive wheel, the idler wheel, and the multiple road wheels, with the first, second, and third directions perpendicular to each other. When the polar vehicle is traveling on rough roads, the torsion bar spring independent suspension cannot provide sufficient support for the road wheels. At this time, the shock absorber plays a supporting role for the chassis. When the shock absorber is compressed and stretched, it generates damping force, which can attenuate the vibration energy of the vehicle during driving and reduce the pitch of the polar vehicle.

[0038] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0039] like Figures 1 to 7As shown, this embodiment provides a polar vehicle, which includes a chassis 1 and a tracked walking mechanism 2. There are two tracked walking mechanisms 2, which are respectively arranged on both sides of the chassis 1 along the first direction X. The tracked walking mechanism 2 includes a drive wheel 21, an idler wheel 22, a track 23, two shock absorbers 24, multiple road wheels 25, and multiple torsion bar spring independent suspensions 26. The drive wheel 21 and the idler wheel 22 are spaced apart on the chassis 1 along the second direction Y. The multiple road wheels 25 are arranged on the chassis 1 one-to-one through the multiple torsion bar spring independent suspensions 26 and are located between the drive wheel 21 and the idler wheel 22. One end of the shock absorber 24 is hinged to the chassis 1, and the other end is hinged to the road wheel 25 near the drive wheel 21 or near the idler wheel 22. The shock absorber 24 is arranged along the third direction Z. The track 23 is arranged around the drive wheel 21, the idler wheel 22, and the multiple road wheels 25. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other. When the polar vehicle is traveling on rough roads, the torsion bar spring independent suspension 26 cannot provide sufficient support for the road wheels 25. At this time, the shock absorber supports the chassis 1. When the shock absorber 24 is compressed and stretched, it generates damping force, which can attenuate the vibration energy of the vehicle during driving and reduce the pitch of the polar vehicle.

[0040] Specifically, the first direction X is the width direction of chassis 1, the second direction Y is the length direction of chassis 1, which is also the forward and backward direction of chassis 1, and the third direction Z is the height direction of chassis 1.

[0041] like Figure 4 As shown, optionally, the track 23 includes multiple metal track plates 231, which are pivotally connected in sequence to form a ring structure. The contact surfaces of the metal track plates 231 are provided with gripping ribs 2311. In this embodiment, a pin passes through the pivot holes of two adjacent metal track plates 231, and two anti-loosening nuts 273 are screwed to both ends of the pin, thereby preventing the pin from detaching from the metal track plate 231. The metal track plates 231 are integrally precision-cast from low-temperature wear-resistant material. The contact surfaces of the metal track plates 231 are provided with interlaced gripping ribs 2311 in a figure-eight shape. This configuration improves the wear resistance of the track 23, enabling long-term stable use, and also enhances the gripping ability of the track 23, preventing it from slipping on icy or snowy surfaces.

[0042] Optionally, the outer circumferential surfaces of the road wheel 25 and the idler wheel 22 are provided with an elastic rubber layer. In this embodiment, the road wheel 25 and the idler wheel 22 have the same structure, both being single-rim structures, mainly including a wheel body and an elastic rubber layer. During vehicle operation, the road wheel 25 and the idler wheel 22 roll on the track surface of the track 23 with relatively small friction, supporting the weight of the vehicle body. The wheel body is made of 20CrMnTi material and is hollow inside to reduce weight. The outer circumferential surface of the rim is vulcanized with an elastic rubber layer to reduce vibration during vehicle operation.

[0043] like Figure 5 As shown, optionally, the tracked walking mechanism 2 also includes a track adjuster 27. The track adjuster 27 includes a lead screw 271, a sleeve 272, a nut 273, and a torsion bar spring 274. The nut 273 is disposed at one end of the sleeve 272 and rotates around the axis of the sleeve 272 in a rotatable engagement with the sleeve 272. One end of the lead screw 271 is inserted into the sleeve 272 from the other end and screwed to the nut 273. The idler wheel 22 is disposed on the sleeve 272. The other end of the lead screw 271 is pivotally connected to the chassis 1. One end of the torsion bar spring 274 is fixedly connected to the other end of the lead screw 271 and the other end of the torsion bar spring 274 is fixedly connected to the chassis 1. In this embodiment, by rotating the nut 273, the relative position of the lead screw 271 and the sleeve 272 can be adjusted, thereby adjusting the relative distance between the idler wheel 22 and the drive wheel 21 along the second direction Y, ultimately realizing the tension adjustment of the track 23. The torsion bar spring 274 of the track adjuster 27 has the same function as the torsion bar spring 274 in the torsion bar spring independent suspension 26, which provides support for the idler wheel 22.

[0044] like Figure 6 As shown, optionally, the polar vehicle also includes an electric drive mechanism 28, which includes a controller 283, a cooling assembly, and two motors 282. The two motors 282 are respectively connected to two drive wheels 21. The cooling assembly includes a water pump 2811, a radiator 2812, and a fan 2813. The controller 283 and the two motors 282 are all equipped with water cooling radiators. The radiator 2812, the water pump 2811, the water cooling radiator of the controller 283, and the water cooling radiator of the two motors 282 are connected in series. The fan 2813 is used to dissipate heat from the radiator 2812. In this embodiment, the radiator 2812, water pump 2811, water-cooled radiator of controller 283, and water-cooled radiators of two motors 282 are connected in series to form a circulation loop. Water pump 2811 drives the condensate in the circulation loop to circulate. After flowing through the water-cooled radiators of controller 283 and two motors 282, the condensate carries away the heat from these components. The heated condensate is then cooled by the radiator 2812. Specifically, when the temperature of controller 283 and motor 282 is below a preset value 'a', fan 2813 does not operate. When the temperature of controller 283 and / or motor 282 is above the preset value 'a', fan 2813 starts operating. Specifically, the preset value 'a' can be 40°C, 45°C, or 50°C, etc.

[0045] Optionally, the cooling assembly also includes a water tank 2814, the outlet of which is connected to the pipeline between the radiator 2812 and the water pump 2811, and the exhaust port of the radiator 2812 is connected to the air inlet of the water tank 2814. In this embodiment, when the condensate in the circulation loop is insufficient, the water tank 2814 can replenish the cooling water in the circulation loop in real time.

[0046] like Figures 1-3 As shown, optionally, the polar vehicle also includes a body shell 3, which is fixed to the chassis 1. The surface of the body shell 3 along the third direction Z is flat. In this embodiment, since the polar vehicle operates for extended periods in environments such as wind, sand, rain, and snow without maintenance, to prevent the accumulation of sand, rainwater, or snow on the body shell 3, the surface of the body shell 3 along the third direction Z is made flat, thus avoiding the accumulation of sand, rainwater, or snow. Furthermore, the flat surface of the body shell 3 along the third direction Z can serve as a mounting platform, where seats, stretchers, luggage racks, or drone landing gear can be installed. Specifically, lights are embedded in the body shell 3, flush with the outer surface of the body shell 3; this design helps prevent the accumulation of sand, rainwater, or snow.

[0047] Optionally, the vehicle body 3 is provided with a mounting cavity; the polar vehicle also includes a power battery mechanism and an electric transmission mechanism 28, which are spaced apart at both ends of the mounting cavity along the second direction Y. In this embodiment, since the power battery mechanism and the electric transmission mechanism 28 are both relatively heavy, in order to ensure the balance of the polar vehicle and prevent it from tilting to the side, they are spaced apart at both ends of the mounting cavity along the second direction Y, so that the polar vehicle remains balanced along the second direction Y.

[0048] like Figure 7 As shown, the polar vehicle also includes a heating mechanism 4, which includes an oil tank 41, an igniter 42, a burner 43, a vaporization screen 44, a combustion-supporting impeller 45, an oil pump 46, a heat exchanger 47, and an exhaust fan 48. The burner 43 has a combustion chamber and an air intake chamber connected to the combustion chamber. The vaporization screen 44 is located in the combustion chamber. The oil tank 41, oil pump 46, and vaporization screen 44 are connected in sequence. The combustion-supporting impeller 45 is used to send combustion-supporting gas through the air intake chamber to the combustion chamber. The igniter 42 is located in the combustion chamber and is used to ignite the oil and gas in the combustion chamber. The heat exchanger 47 is located in the combustion chamber, and its air inlet and outlet are respectively connected to the mounting cavity. The exhaust fan 48 is used to send cold air from the mounting cavity into the air inlet. When the polar vehicle is in an extremely cold environment, the temperature inside the mounting cavity is too low, causing some components inside the mounting cavity to malfunction. Therefore, it is necessary to heat the mounting cavity. At this time, the oil pump 46 sends the oil in the oil tank 41 to the evaporation screen 44. The oil on the evaporation screen 44 evaporates into gas. At this time, the combustion fan blows the combustion gas (which is air) into the combustion chamber. At the same time, the evaporated oil gas mixes with the air to become oil gas. The igniter 42 in the combustion chamber works and ignites the oil gas. The flame of combustion heats the heat exchanger 47. The exhaust fan 48 is used to send the cold air in the installation cavity into the air inlet of the heat exchanger 47. The heated gas flows out from the air outlet of the heat exchanger 47, thereby raising the temperature in the installation cavity.

[0049] Optionally, the heating mechanism 4 also includes an overheat fuse, which is located in the combustion chamber and connected in series with the power supply line of the oil pump 46. In this embodiment, when the temperature of the overheat fuse reaches a preset value b, the overheat fuse trips. Consequently, when the temperature in the combustion chamber reaches the preset value b, the overheat fuse trips, the oil pump 46 stops working, and combustion in the combustion chamber ceases. At this time, the heating mechanism 4 is inspected, and after troubleshooting, the heating fuse is replaced, allowing the heating mechanism 4 to resume operation.

[0050] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
