Description

Technical Field

[0001] This utility model belongs to the field of wheel technology, specifically relating to an all-terrain deformable wheel. Background Technology

[0002] Currently, most vehicle wheels have a circular structure, which can easily cause slippage on certain road surfaces. To overcome this slippage, some vehicles use anti-skid chains or triangular track wheels. Anti-skid chains are generally used in winter because they are heavy and not carried with the vehicle. In summer, they can affect driving speed when encountering soft or muddy road surfaces. Triangular track wheels, on the other hand, have a complex structure, are expensive, and have limited driving speed, so they cannot be widely used. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes an all-terrain deformable wheel.

[0004] The all-terrain deformable wheel of this utility model includes: a hub, with multiple hydraulic cylinders arranged on the outer circumference of the hub; a rotating hydraulic manifold plate, which is fixed to the vehicle body and located inside the hub, and is connected to the hydraulic cylinders; spokes, which are fixedly connected to or integrally formed with the pistons of the hydraulic cylinders; and a chain track, with the track pins of the chain track connected to the ends of the spokes.

[0005] The hub is a disc-shaped object with a groove on one side. Two sets of cylinder oil holes are staggered on the side wall of the groove. Multiple hydraulic cylinders are arranged side by side on the outer circumference of the hub. Each cylinder oil hole is connected to a hydraulic cylinder. The hydraulic cylinders are divided into two groups according to the different positions of the cylinder oil holes. A rotary oil passage plate is installed in the groove.

[0006] The rotary oil passage plate is circular, with two annular oil passages interspersed in the rotary oil passage plate. The cross-section of the two oil passages is U-shaped groove, and each oil passage has an oil filling port. The two oil filling ports are staggered on the side of the rotary oil passage plate.

[0007] The two oil passages in the rotary oil passage plate correspond one-to-one with the two sets of hydraulic cylinders on the hub, and each hydraulic cylinder is connected to the corresponding oil passage in the rotary oil passage plate through the cylinder body oil hole.

[0008] Each pair of adjacent hydraulic cylinders on the outer circumference of the hub is connected to different oil passages, and each hydraulic cylinder is also provided with an oil inlet channel that communicates with the oil hole in the cylinder body.

[0009] Bolt holes are provided between every two adjacent hydraulic cylinders on the outer circumference of the hub, and through holes are provided at the bottom of the groove on the hub.

[0010] The rotating oil passage plate can rotate relative to the wheel hub. The brake disc is installed on the side of the rotating oil passage plate away from the through hole on the wheel hub by bolts. The bolts pass through the brake disc and connect to the bolt holes on the wheel hub. The diameter of the brake disc is larger than the diameter of the wheel hub.

[0011] The spokes are provided with pin holes at their ends, and the opening direction of the pin holes is perpendicular to the length direction of the spokes.

[0012] The chain track includes multiple chain units and multiple track pins. Each chain unit has through holes at both ends. Each track pin passes through a pin hole on a spoke and through holes in two adjacent chain units. The spokes are located between two adjacent chain units.

[0013] The diameter of the pin hole is larger than the diameter of the track pin, and the spokes are located in the middle of the through holes of two adjacent chain units.

[0014] The beneficial effect of this utility model is that the all-terrain deformable wheel of this utility model adjusts the pressure through the vehicle control oil circuit, thereby driving the spoke axle plug to extend or retract through the piston of the hydraulic cylinder, so that the chain track can be connected at different angles, thereby generating different roadbed pressures and achieving maximum power transmission to drive the vehicle forward.

[0028] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0029] like Figures 1-11 As shown, the all-terrain deformable wheel of this utility model includes a hub 2, a rotating hydraulic manifold 1, spokes 3, and a chain track 5. Multiple hydraulic cylinders 9 are arranged on the outer circumference of the hub 2. The rotating hydraulic manifold 1 is fixed to the vehicle body and located inside the hub 2, and is connected to the hydraulic cylinders 9. The spokes 3 are fixedly connected to or integrally formed with the pistons of the hydraulic cylinders 9, so the pistons of the hydraulic cylinders 9 can drive the spokes 3 to extend and retract. The track pins 4 of the chain track 5 are connected to the ends of the spokes 3. The rotating hydraulic manifold 1 is connected to the vehicle control hydraulic circuit to supply hydraulic oil to the hydraulic cylinders 9. By controlling the extension and retraction of the pistons of the hydraulic cylinders 9, the extension and retraction of the spokes 3 can be controlled, thereby controlling the deformation of the chain track 5. When all the pistons of the hydraulic cylinders 9 are extended, the wheel is round, suitable for driving on regular roads; when the pistons of some hydraulic cylinders 9 are retracted and others are extended, the wheel is deformed, suitable for driving on soft and muddy roads, and can also climb.

[0030] like Figure 4As shown, the hub 2 is a disc-shaped structure with a groove on one side. Two sets of cylinder oil holes 8 are staggered on the sidewall of the groove. One set of cylinder oil holes 8 is located near the inner side of the groove, and the other set is located near the outer side. Adjacent cylinder oil holes 8 are staggered. Multiple hydraulic cylinders 9 are arranged side-by-side on the outer circumference of the hub 2. Each cylinder oil hole 8 connects to one hydraulic cylinder 9, meaning that the positions of the cylinder oil holes 8 of adjacent hydraulic cylinders 9 are different. Based on the different positions of the cylinder oil holes 8, the hydraulic cylinders 9 are divided into two groups.

[0031] A rotary oil passage disc 1 is placed in the groove of the wheel hub 2, as follows. Figure 7 As shown, the rotary oil passage plate 1 is annular in shape, with two interlocking annular oil passages 12 within it. One annular oil passage 12 is closer to the center of the ring, and the other is farther away. The two oil passages 12 are independent of each other and not connected. Each oil passage 12 has an oil filling port 11, and the two oil filling ports 11 are staggered on the side of the rotary oil passage plate 1. The oil filling port 11 is connected to the vehicle control oil circuit.

[0032] The two oil passages 12 in the rotary oil passage plate 1 have U-shaped cross sections, and sealing rings are provided on both sides of the U-shaped grooves. The rotary oil passage plate 1 is connected to the inner wall of the hub through the sealing rings.

[0033] Each hydraulic cylinder 9 is also provided with an oil inlet channel that communicates with the cylinder body oil hole 8, and the oil inlet channels of the two sets of hydraulic cylinders 9 are staggered. That is, the hydraulic cylinder 9 is connected to the cylinder body oil hole 8 through the oil inlet channel, and the cylinder body oil hole 8 is connected to the rotary oil passage plate 1. Specifically, the oil inlet channel can be inserted into the cylinder body oil hole 8 or the oil inlet channel and the cylinder body oil hole 8 can be integrally formed.

[0034] The two oil passages 12 in the rotary oil passage plate 1 correspond one-to-one with the two sets of hydraulic cylinders 9 on the wheel hub 2. Each hydraulic cylinder 9 is connected to the corresponding oil passage 12 in the rotary oil passage plate 1 through the cylinder body oil hole 8. Each pair of adjacent hydraulic cylinders 9 on the outer circumference of the wheel hub 2 are connected to different oil passages 12.

[0035] like Figure 4 and Figure 5 As shown, a fixing plate is provided between every two adjacent hydraulic cylinders 9 on the outer circumference of the hub 2. The fixing plate is provided with bolt holes 10, and a through hole is provided at the bottom of the groove on the hub 2.

[0036] like Figure 3 As shown, the brake disc 6 is installed on the side of the rotary oil passage plate 1 away from the through hole on the wheel hub 2 by bolts 7. The bolts 7 pass through the brake disc 6 and connect to the bolt hole 10 on the wheel hub 2, thereby connecting the brake disc 6 to the wheel hub 2. The diameter of the brake disc 6 is larger than the diameter of the groove in the wheel hub 2.

[0037] The rotary oil passage plate 1 can rotate relative to the wheel hub 2, that is, the rotary oil passage plate 1 can rotate inside the wheel hub 2. Specifically, the rotary oil passage plate 1 is provided with oil passage plate bolt holes, and the rotary oil passage plate 1 is connected and fixed to the vehicle body through the oil passage plate bolt holes, and the vehicle drives the rotary oil passage plate 1 to rotate.

[0038] The end of the spoke 3 is provided with a pin hole, and the opening direction of the pin hole is perpendicular to the length direction of the spoke 3. The diameter of the pin hole is larger than the diameter of the track pin 4, so that the track pin 4 can be inserted into the pin hole of the spoke 3.

[0039] The chain track 5 includes multiple chain units 14 and multiple track pins 4, such as Figure 10 As shown, each chain unit 14 has through holes 15 at both ends. Each track pin 4 passes through a pin hole on a spoke 3 and through holes 15 in two adjacent chain units 14. The spoke 3 is located between two adjacent chain units 14.

[0040] like Figure 1 and 11 As shown, the spoke 3 is located in the middle of the perforation 15 of two adjacent chain units 14.

[0041] The spokes 3 extend or retract under the action of the hydraulic cylinder 9. During the movement, the spokes 3 drive the two adjacent chain units 14 to move accordingly via the track pin 4. If the actions of the two adjacent hydraulic cylinders 9 are opposite, the chain track 5 will be in a deformed state.

[0042] In use, the two oil inlets 11 in the rotary hydraulic manifold 1 are connected to the vehicle control hydraulic circuit. Hydraulic oil is injected into the hydraulic cylinders 9 through the rotary hydraulic manifold 1. Under the action of the same hydraulic oil pressure in all hydraulic cylinders 9, all spokes 3 extend, making the chain track 5 form a circular wheel structure, which can realize the shock absorption and obstacle crossing functions of the wheels. When the hydraulic oil pressure in two adjacent hydraulic cylinders 9 is different, that is, the hydraulic oil pressure in the two sets of hydraulic cylinders 9 is different, the extension length of the spokes 3 connected to the two sets of hydraulic cylinders 9 is different, or one set extends and the other retracts, so that the adjacent chain units 14 of the chain track 5 are connected at different angles, that is, the chain track 5 deforms, thereby generating different roadbed pressure, realizing maximum power transmission and driving the vehicle forward.
