Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the existing lunar wheels are not suitable for climbing. Because the wheels cannot go deep into the lunar soil, sliding friction is likely to occur relative to the lunar soil, that is, the sliding phenomenon; because the wheel teeth are narrow, idling is easy to occur, that is, the slipping phenomenon , so that the lunar wheel is caught in the lunar soil and slips, which causes the problem that the lunar rover cannot work normally, and then provides a spiral lunar rover wheel

specific Embodiment approach 1

[0007] Specific implementation mode one: combine figure 1 and figure 2 Describe this embodiment, this embodiment consists of two wheel bodies 1, a wheel shaft 3, two helical blades 2, a driven bevel gear shaft 4, a driving bevel gear shaft 5, a fixed frame 6, a soft casing 7, and a drive cable 8 , a motor 9 and a car body 10, the two wheel bodies 1 are symmetrically fixed on both ends of the wheel shaft 3, and the outer walls of the two wheel bodies 1 are respectively provided with a helical blade 2 along the axial direction. The driven bevel gear shaft 4 is installed on the wheel shaft 3, the driving bevel gear shaft 5 is installed on the beam 6-1 of the fixed frame 6, the driving bevel gear shaft 5 is meshed with the driven bevel gear shaft 4, and the wheel shaft 3 is connected to the car body 10 through the fixing frame 6, the motor 9 is arranged in the car body 10, one end of the driving cable 8 is connected to the driving bevel gear shaft 5, and the other end of the dri...

specific Embodiment approach 2

[0008] Specific implementation mode two: combination figure 1 and figure 2 To describe this embodiment, the two ends of the two wheel bodies 1 in this embodiment away from the wheel shaft 3 are tapered, and the two ends of the two wheel bodies 1 close to the wheel shaft 3 are in the shape of a truncated cone. Set it up to keep moving with less resistance and faster speeds. Other compositions and connections are the same as in the first embodiment.

[0009] working principle:

[0010] Such as figure 2 As shown, the motor 9 works and rotates, driving the driving cable 8 connected thereto to rotate, the driving cable 8 and the driving bevel gear shaft 5 are connected as one, and the driving bevel gear shaft 5 drives the driven bevel gear shaft 4 to rotate, from The bevel gear shaft 4 is integrated with the wheel body 1 and the wheel shaft 3, so the motor 9 drives the wheel body 1 to rotate. Since the soft casing 7 and the driving cable 8 are flexible structures with a cert...

Abstract

The invention provides a spiral lunar rover wheel, and more particularly relates to a lunar rover wheel. The spiral lunar rover wheel solves the problems that as the wheel can not be deep in the lunar soil and is easy to generate sliding friction (namely sliding phenomena) correspondingly to the lunar soil, the existing lunar rover wheel is not suitable for mountain climbing; as the wheel is narrow, the driving force and the supporting force are small, idle rotation is easy to occur, thus generating the sliding phenomena and leading the lunar rover wheel to be sunk into the lunar soil and the lunar rover not to run normally. The spiral lunar rover wheel consists of two wheel bodies (1), a wheel shaft (3) and two spiral vanes (2); two wheel bodies (1) are fixedly connected with two ends of the wheel shaft (3) symmetrically; the external walls of the two wheel bodies are respectively provided with one spiral vane (2) along the direction of the axis line. The spiral lunar rover wheel is suitable for mountain climbing, is not easy to generate the sliding friction correspondingly to the lunar soil, has large power, is not easy to generate the idle rotation (namely the sliding phenomena), has quick speed and few driving system and is easy to be controlled; during the heading process, the lunar wheel always keeps the moving trend on the lunar surface, thus leading the lunar rover to run normally; the spiral lunar rover wheel is especially suitable for mountain climbing.

Description

technical field [0001] The invention relates to a lunar vehicle wheel. Background technique [0002] The lunar environment mainly includes the lunar gravitational field, magnetic field, radiation, atmosphere, meteoroids, lunar surface temperature, lunar dust, lunar soil, and lunar surface topography, among which the lunar gravity field, lunar soil, and lunar surface topography and other environments are the most important factors. Influencing factors of the lunar rover's forward movement. The moon is small in size and light in mass, and its gravitational acceleration is only 1 / 6 of the earth's gravitational acceleration, that is, (1 / 6)g. When the lunar rover walks on it, due to its low gravity, the friction with the ground is also small, and its acceleration is also small according to Newton's second law. Lunar regolith is a layer of regolith on the surface of the moon, consisting of a fine and sticky ion layer less than 1 mm in diameter, with few rocks scattered in it. F...
