Embodiment 1

[0031] Such as Figure 1-7 Shown, a kind of lunar rover wheel with auxiliary fin of the present invention, wheel comprises wheel hub and tire 1, is provided with auxiliary fin 2 on at least one side of tire 1, can be only one side, also can two sides at the same time Setting; one end of the auxiliary fin 2 is the connection end 8, which is connected to the side of the tire 1, and the end opposite to the connection end 8 is the open end 9, and the direction from the connection end 8 to the open end 9 of the auxiliary fin 2 is in line with the radial direction of the tire 1 consistent, and the auxiliary fin 2 from the connecting end 8 to the open end 9 is arc-shaped gradually away from the side of the tire 1, the vertical height from the lowest point of the auxiliary fin 2 to the extension line of the axis of the tire 1 is not greater than the rolling radius of the tire 1, and the hub Installed on the hub installation shaft, the auxiliary fins 2 are not less than four, and are d...

Embodiment 2

[0036] Such as Figure 1-7 As shown, a lunar vehicle wheel with auxiliary fins of the present invention, its wheel auxiliary fin 2 structure is basically the same as that of embodiment 1, the difference is that the connecting end 8 of the auxiliary fin 2 is hinged on the tire 1 On the side, the hub is installed on the hub installation shaft, and the axial side of the hub installation shaft is provided with an eccentric wheel 5. The eccentric wheel 5 is coaxial with the hub installation shaft. The wheel 5 is equipped with an eccentric wheel disc 7 through the eccentric wheel bearing 6, and the eccentric wheel disc 7 is provided with a connecting rod 4, and the connecting rod 4 is connected with the auxiliary fin 2 on the tire 1, and the eccentric wheel on the same side of the tire 1 The wheel disk 7 is provided with mounting holes corresponding to the number and positions of the 2 auxiliary fins on the same side. The mounting direction of the connecting rod 4 is consistent with...

Abstract

The invention relates to the field of lunar vehicles, in particular to a wheel with auxiliary fins for moonscape exploration tour vehicles and other deep space exploration tour vehicles. The wheel comprises a hub and a tire, wherein auxiliary fins are arranged on at least one side surface of the tire, one ends of the auxiliary fins are connecting ends connected to the side surface of the tire, ends of the auxiliary fins, opposite to the connecting ends, are opening ends, the direction of the connecting ends of the auxiliary fins to the opening ends of the auxiliary fins is consistent to the radius ray direction of the tire, the auxiliary fins are shaped as an arc being gradually away from the side surface of the tire from the connecting ends to the opening ends, and a vertical height fromthe lowest point of the auxiliary fins to the extended axis line of the tire is not more than the rolling radius of the tire. When the wheel is driven to run on the soft ground, because thrust of soil enables the auxiliary fins to be deformed or the auxiliary fins are driven by an eccentric wheel to swing upwards, a contact part of the whole wheel and the ground is widened, the fins share partialwheel loads and prevent the wheel from further sinking, thus the soft ground passing capacity of the wheel is improved.

Description

Technical field: [0001] The invention relates to the field of lunar vehicles, in particular to a wheel with auxiliary fins for deep-space exploration patrol vehicles on the surface of the moon. Background technique: [0002] Most of the current interstellar exploration vehicles and lunar rovers use wheeled as the main configuration. The wheel is one of the most critical components of the interstellar exploration vehicle and the lunar rover walking system. It undertakes the important function of supporting the whole vehicle from sinking and converting the rotational motion of the wheel drive device into the forward motion of the vehicle. Counting the successfully launched interstellar exploration vehicles, the following two structural forms are the main structural forms of interstellar exploration vehicles. [0003] a) Metal rigid wheels; such as the Mars rover "Sojourney" and "Opportunity" launched by the United States; [0004] b) Elastic sieve wheels; such as the lunar r...
