Problems solved by technology

[0004] The topography of the surface of Mars is complex, including deserts, glacial deposits, mountains, etc. To adapt to various terrains, the wheels must have strong passability when moving on the surface of Mars. In the past, the size and characteristics of the wheels could not be well adapted to the surface environment of Mars. , it is necessary to design special wheels for the special surface characteristics of Mars

Embodiment Construction

[0027] The invention will be described in more detail hereinafter with reference to the accompanying drawings showing embodiments of the invention. However, the present invention may be embodied in many different forms and should not be construed as limited by the

[0028] limitations of the examples.

[0029] Such as figure 1 As shown, the wheel adapted to the Mars terrain environment in the embodiment of the present invention includes a wheel body, a wheel drive interface 1, a spoke 2, a driving mechanism, a rim 3, and a pawl 4; Wheels and rims use a drum-shaped wheel surface, the edge diameter of the wheel surface is 320mm, the middle diameter of the wheel surface is 356.5mm, the thickness of the drum surface is 3mm, and the material is aluminum alloy. The wheel surface is a non-elastic surface, which does not deform during the contact with the ground, so that the movement resistance during the forward process is small. Lightweight aluminum alloy is selected as the mater...

Abstract

The invention discloses a wheel suitable for the terrain environment of the Mars. The wheel comprises a wheel body, a wheel driving joint, spokes, a driving mechanism, a hub, and pawls, wherein the wheel driving joint enables the wheel body and the driving mechanism to be connected, and connection joints connecting the spokes and connecting the driving mechanism are respectively designed; the wheel driving joint is connected with the spokes through screws and nuts; the spokes are rigid spokes and are mounted on one side of the wheel; the driving mechanism is arranged at the inner part of the hub; the spokes are connected with the hub through screws and nuts; the pawls are connected with the hub through screws and nuts. The wheel is beautiful in structural appearance, easy in machining, compact in structure, high in passability on the surface of the Mars and high in strength, can bear the weight of a Mars patrolling device, and can bear certain torque.

Description

technical field [0001] The invention relates to a wheel adapted to the terrain environment of Mars. The wheel can provide strong driving force and strong bearing capacity, and is suitable for walking on the surface of Mars. [0002] Background technique [0003] Wheels are an important part of the planetary rovers, they need to carry the full weight of the rovers and have sufficient strength. [0004] The topography of the surface of Mars is complex, including deserts, glacial deposits, mountains, etc. To adapt to various terrains, the wheels must have strong passability when moving on the surface of Mars. In the past, the size and characteristics of the wheels could not be well adapted to the surface environment of Mars. , It is necessary to design special wheels for the special surface characteristics of Mars. [0005] Therefore, the industry needs a wheel that adapts to the terrain environment of Mars to realize the functions of advancing, retreating, steering, braking,...
