Frame folding mechanism of manned lunar rover

Abstract

The invention discloses a frame folding mechanism for a manned moon rover. A front frame and a rear frame are of the same structure and are symmetrically arranged with respect to a middle frame. Both the front frame and the rear frame are hinged to the middle frame so that the front frame and the rear frame can be folded oppositely. Middle wheels are symmetrically mounted on the left side and the right side of the middle frame. Front wheels are symmetrically arranged on the left side and the right side of the front end of the front frame. Rear wheels are symmetrically arranged on the left side and the right side of the rear end of the rear frame. The front wheels and the rear wheels are hinged to suspensions on the corresponding frames so that the front wheels and the rear wheels can swing upwards in the pitching direction. When the front frame and the rear frame are oppositely folded in place, each front wheel and the rear wheel on the corresponding side are attached together. According to the frame folding mechanism for the manned moon rover, the frames and a moving system can be highly folded, the folding ratio of the manned moon rover is effectively increased, and the initial storage volume of the manned moon rover in the launching process is reduced; the frame folding mechanism has the characteristics of being reasonable in design, easy to implement, low in cost and the like; and folding is easy, convenient and fast, and the whole manned moon rover is regular and attractive in appearance and convenient to carry after being folded.

Description

technical field [0001] The invention relates to a manned lunar vehicle, in particular to a frame folding mechanism of a manned lunar vehicle. Background technique [0002] Manned lunar exploration is not only a country's level of scientific and technological development, but also a concrete manifestation of comprehensive national strength. To realize lunar surface exploration, transportation of effective scientific payloads, collection of samples, and long-term residence of astronauts on the lunar surface, the manned lunar vehicle must be an indispensable and important medium and detection tool. In order to effectively guarantee the safety of astronauts and efficiently complete the mission of lunar surface exploration, the manned lunar vehicle must have good mobility, carrying capacity, full support capability and human-computer interaction capability on the lunar surface. [0003] Various countries in the world have proposed manned lunar rovers of different structures, whi...

Problems solved by technology

However, the folding ratio of the chassis of the Apollo manned lunar rover is small, and the Ackermann steering scheme of traditional vehicles is adopted, so that when it is driving on a steep slope or a cross slope, the manned lunar rover is prone to bumps and vibrations, which reduces the manned capacity.
