TECHNICAL FIELD

[0001] The present application relates to the field of vehicle wheels, and more particularly to a full-terrain rigid wheel. BACKGROUND

[0002] The passing performance of a vehicle is a key factor in determining the quality of its tasks such as detection, transportation, and mining. Whether it is an extreme environment such as a desert, a beach, or a gobi on earth, or a complex environment in deep space of an alien planet, they all have the common feature of working in loose ground. When a vehicle travels on loose or muddy ground with poor load-carrying capacity, the wheels are prone to slip and even over-sink, causing the vehicle to be trapped and unable to move on. With the continuous progress of space technology, deep space exploration projects such as the moon, Mars, and asteroids are gradually being carried out, and future exploration tasks may bring high slip and high subsidence working conditions. The existing Mars rover has been trapped in soft sand and cannot adapt to various ground working environments.

[0015] The above further technical solution has the beneficial effect of ensuring that the hollow area formed between the soil-pushing piece and the bead does not participate in the load bearing of the wheel, and that the soil-pushing method can be used to obtain a path of advancement in the soft ground.

[0016] Further, the all-terrain rigid wheel further comprises a plurality of inner tire baffles, each of which is mounted on the circumferential surface of the hub and is distributed equidistantly in the circumferential direction, and corresponds to the position of the inner open space formed between the two beads.

[0032] ​The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] like Figures 1-6 As shown, this embodiment of the invention discloses an all-terrain rigid wheel, including a hub 1 and a tire 2. In this embodiment, there are multiple tires 2, which are arranged side by side at equal intervals on the circumferential surface of the hub 1. Each tire 2 includes two bead 21, multiple tread plates 22, and two tread collars 23. The two bead 21 are respectively symmetrically mounted on the circumferential surface of the hub 1. The multiple tread plates 22 are respectively fixed between the two bead 21 and are evenly distributed along the circumference. The two tread collars 23 are respectively fitted and fixed on the outer circumferential edge of the two bead 21. This invention relies on the outer edge of the tread ring 23 to support the ground, possessing sufficient hardness and width to meet the requirements of supporting rigidity and torque driving force on the ground. At the same time, the space formed by the tire bead 21 and the soil-pulling plate 22 has the ability to accumulate soil, enabling the transfer of soil from the front of the wheel. The inner sides of the two tire bead 21 are open, allowing the accumulated soft media to move within the space enclosed by the two tire bead 21 and be discharged through the open inner side during the wheel's forward movement, without producing a soil-fixing effect. This changes the driving mode on soft and muddy ground. After the wheel sinks, the soil-pulling plate 22 provides forward momentum, transferring the soft media from the front of the wheel to the rear, providing a path for the wheel to move forward. This effectively improves the wheel's ability to get out of trouble on soft ground, while also possessing high load-bearing capacity on hard ground, achieving high passability, and can be applied to all terrains.

[0034] To further optimize the technical solution of the present invention, multiple soil-dispersing pieces 22 are V-shaped or U-shaped to obtain a soil-aggregating range.

[0035] To further optimize the technical solution of the present invention, each soil-removing piece 22 is at an angle of 0-45° to the diameter direction of the wheel, thereby ensuring that the area where the wheel is sunk into the soft medium has a continuous soil-removing ability.

[0036] To further optimize the technical solution of the present invention, the outer end of each soil-digging piece 22 is lower than the outer edge of the tire bead 21, thereby ensuring that the hollow area formed between the soil-digging piece 22 and the tire bead 21 does not participate in the wheel load-bearing, and can obtain a forward path by digging soil when stuck in soft ground.

[0037] Specifically, the all-terrain rigid wheel further comprises a plurality of inner tire baffles 3 or a plurality of groups of inner tire baffles, in the embodiment, a plurality of groups of inner tire baffles are selected to be arranged, and the plurality of groups of inner tire baffles are arranged on the circumferential surface of the hub 1 and are distributed in parallel at equal intervals; each group of inner tire baffles comprises a plurality of inner tire baffles 3, the plurality of inner tire baffles 3 are arranged on the circumferential surface of the hub 1 and are distributed in parallel at equal intervals, and correspond to the positions of the inner open spaces formed between the two beads 21 of the same tire 2, so as to control the sinking amount of the wheel on the soft ground.

[0038] Specifically, the hub 1 comprises a flange 11, a plurality of spokes 12 and a plurality of rims 13 which are connected as a whole from inside to outside, each rim 13 comprises one or more support arms 13 which are connected as a whole in parallel, in the embodiment, a plurality of support arms 13 which are connected as a whole in parallel, each support arm 13 comprises two symmetrical support plates 131 which are connected as a whole, each support plate 131 has a clamping groove 1311 on the outer side, and the bead 21 is clamped and fixed in the clamping groove 1311 to provide support and torque transmission for the tire 2; the inner tire baffle 3 is located between the two support plates 131 and is connected with the two support plates 131 in a sliding manner, so that the inner tire baffle 3 has a single degree of freedom and can slide in the inner-outer direction to adjust the sinking amount of the wheel, of course, in the embodiment, the inner tire baffle 3 and the support plate 131 can be connected through a linear guide rail to realize sliding connection and fixation at any position.

[0039] Specifically, each inner tire baffle 3 comprises two inner tire half baffles which are symmetrically distributed and are connected with the two support plates 131 on both sides in a sliding manner.

[0040] Specifically, the width of the inner tire half baffle is smaller than the width between the two beads 21, so that the inner tire baffle 3 can ensure that the wheel does not produce continuous closed tread when fixed at any position.

[0041] The working principle of the present application is as follows:

[0042] As shown in Figure 4 When driving on soft or muddy ground, the wheel sinks due to the absence of tread structure, and the tread sleeve ring 23 has a small support force area, so the soil-shifting piece 22 sinks into the soft medium, and the outer edge of the soil-shifting piece 22 contacts the soft medium and gradually sinks into the soft medium when the wheel rotates, pushing the soft medium to move backward, and through the soil-shifting action of the soil-shifting piece 22, the forward power is obtained, and the soft medium is transferred from the front side of the wheel to the rear side of the wheel to obtain a forward path for the wheel.

[0043] As shown in Figure 5As shown, when running on flat hard ground, the wheel does not penetrate the ground, and the tire sleeve ring 23 provides support and drive to achieve passability as a support member in direct contact with the ground. Of course, the wheel can be improved for different vehicle load conditions. Under heavy load conditions, the width of the tire sleeve ring 23 can be increased to improve the load carrying capacity of the wheel.

[0044] As shown, when running on flat hard ground, the wheel does not penetrate the ground, and the tire sleeve ring 23 provides support and drive to achieve passability as a support member in direct contact with the ground. Of course, the wheel can be improved for different vehicle load conditions. Under heavy load conditions, the width of the tire sleeve ring 23 can be increased to improve the load carrying capacity of the wheel.
