Embodiment Construction

[0036] Such as figure 1 Shown is a schematic diagram of the basic composition and structure of the present invention. The three planetary wheel wheels 1 are installed on the double-wheel frame 2 and the single-wheel frame 10 respectively, and the double-wheel frame 2 and the single-wheel frame 10 are installed on the rotating part 16, and all can rotate around the axis of rotation on the car body. Rotate, thereby forming a planetary wheel 17. The two planetary wheels are arranged on the left and right sides of the car body, and are connected by a synchronizing device 8 in the middle. Each wheel is independently driven, and the driver and the wheel are integrated.

[0037] Such as figure 2 Shown is a cross-sectional view of the middle rotating part of the planetary wheel of the present invention. exist figure 2 Among them, the wheel mounting frame 2-1 of the double-wheel frame is installed on the gear core sleeve 2-3, and the single-wheel frame 10 is installed on the spi...

Abstract

The invention discloses a walking system of planet vehicle with planet gear, comprising vehicle body, two planet gears and pre and post assistant wheels. Said planet wheels are set at left and right sides of vehicle body respectively and they are connected by synchronic device in the middle. Said pre and post assistant wheels are set at the front and the back of vehicle body and they are connected by linkage device set at the center of vehicle body in the middle. The invention not only realizes the improvement of passing capacity of vehicle in soft land and obstacle but also makes vehicle possess the capacity that vehicle can be folded and unfolded; the distance between vehicle body and the land can be adjusted; the whole vehicle can be oblique and there is pre-selecting driving project.

Description

technical field [0001] The invention relates to an extraterrestrial vehicle for spaceflight, in particular to a traveling system of a planetary wheel type planetary vehicle. Background technique [0002] The current extraterrestrial exploration vehicles mostly use the multi-wheel side-by-side rocker suspension mechanism as the main configuration of the walking system. For example, the "lunar vehicle 1" launched by the Soviet Union adopted a parallel 8-wheel structure with unilateral double rocker suspension. The Mars rovers "Sojourney" and "Opportunity" launched by the United States adopted a 3-wheel rocker suspension structure developed from a 2-wheel rocker suspension on one side. But this kind of suspension is far from enough to pass through the complex environment unknown to the alien body. At the end of April 2005, the US "Opportunity" Mars rover was immobilized due to driving on a 30-centimeter-high sand pile, and was trapped for a month. [0003] As another example...
