Embodiment Construction

[0026] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0027] Such as figure 1 As shown, a wheel-shoe autonomously switches planetary vehicle wheels, including a wheel-shoe switching mechanism and a wheel-shoe driving mechanism. The wheel-shoe switching mechanism includes an annular belt body 6 that can be switched into a wheel or a track, a switching sun gear 1, and a switching planetary gear assembly The switching planetary gear assembly includes a switching planetary wheel 2 and a switching support assembly, the switching sun gear 1 is meshed with the switching planetary gear 2, and the switching planetary gear 2 drives the switching support assembly so that the annular belt body 6 is in a wheel state or a track state;

Abstract

The invention relates to a wheel of planet vehicle capable of automatically switching between wheels and tracks. The wheel comprises a wheel-track switching mechanism and a wheel-track driving mechanism, the wheel-track switching mechanism comprises an annular belt body capable of being switched into a wheel or a track, a switching sun wheel and a switching planet wheel assembly, and the wheel-track driving mechanism comprises a driving sun wheel and a driving moving assembly. The wheel is novel in design and stable in structure, the switching planet wheel is designed to drive the switching supporting assembly so that the annular belt body can be in a wheel state or a crawler belt state, the annular belt body can be automatically switched between a wheel type state and a crawler belt type state, and meanwhile power coaxial input of the switching sun wheel and the driving sun wheel is achieved. The driving sun wheel and the driving planet wheel are in transmission connection through the transmission belt annularly arranged between the driving sun wheel and the driving planet wheel, the driving planet wheel is in attached abutting connection with the annular belt body through the transmission belt for transmission, the annular belt body can be in a meshing transmission state all the time in the wheel-track switching process, and continuous movement without impact is kept.

Description

technical field [0001] The invention relates to the field of deep space detection devices, in particular to a track for autonomously switching planetary vehicles. Background technique [0002] The planetary vehicle travels on different planets, and its terrain is complex and changeable, including flat ground, soft soil, gravel road, gravel road, etc. The wheeled mobile method has the advantages of high moving efficiency and fast speed. Among the existing lunar vehicles and It is widely used on Mars rovers, but its carrying capacity is limited, it is prone to subsidence under soft soil, and it is difficult to climb on soft slopes. The tracked wheel assembly has good supporting capacity, a large contact area on soft ground, and strong climbing ability, but its moving efficiency is low and the speed is slow. [0003] The general wheel-track composite wheel is a wheel type and a track type, both of which exist independently. When the wheel moves, the track is lifted; when the t...
