Problems solved by technology

[0003] The purpose of the present invention is to provide a lever-side mobile shock-absorbing four-wheeled vehicle-mounted lunar vehicle folding system to solve the problems of overall overturning, climbing obstacles, and sinking into potholes that are prone to occur on four-wheeled vehicles under the complex geographical environment on the surface of the planet. And problems such as heavy operation of the vehicle body, high energy consumption, weak adaptability, and large space occupation hinder the implementation of detection tasks.

specific Embodiment approach 1

[0014] Specific implementation mode one: combine Figure 1 to Figure 6 Describe this embodiment, the system of this embodiment comprises load plate car body 1, two intermediate connection folding mechanisms 8, four double-wheel moving mechanisms and four lever-type coaxial sleeve spring mechanisms, load plate car body 1 is formed by the first The car body 1-1 and the second car body 1-2 are composed of two right-angle channel steels 6 welded on one side of the first car body 1-1, and the other side of the first car body 1-1 is connected through two intermediate The folding mechanism 8 is folded and connected to one side of the second car body 1-2, and the other side of the second car body 1-2 is welded with two right-angled channel steels 6, and the first car body 1-1 passes through a pair of rolling pins 9 and the nail groove 15 are detachably connected with the second car body 1-2, and four double-wheel moving mechanisms are evenly distributed on the lower end surface of the...

specific Embodiment approach 2

[0019] Specific implementation mode two: combination Figure 6 To illustrate this embodiment, the coaxial sleeve spring 10 of this embodiment includes a swing arm type shock absorbing flap 16, a tension and compression axial spring 17 and a bending moment axial sleeve 18, and the tension and compression axial spring 17 is sleeved on the sleeve 18. The outside and the sleeve are stretchable in the tension-compression axial spring 17, and the bottom of the tension-compression axial spring 17 and the bending moment axial sleeve 18 is provided with a swing arm type shock-absorbing flap 16, which can effectively slow down the lateral vibration. Avoid bending and twisting mode of action, while increasing the reliability of the structure. Other implementation manners are the same as the specific implementation manner 1.

specific Embodiment approach 3

[0020] Specific implementation mode three: combination figure 1 To illustrate this embodiment, each lever plate 11 of this embodiment is processed to be hollow above the corresponding wheel body 4. This structure can reduce the weight of the shock absorbing mechanism, and at the same time avoid sand and other deposits in the shock absorbing structure. Other implementation manners are the same as the specific implementation manner 1.

[0021] Working principle: the present invention adjusts the direction of avoiding obstacles through four independently driven and steered wheels, and uses the swing arm type lever side to move the axial sleeve spring damping mechanism to reduce the impact on the structure itself when starting a slope and crossing obstacles. The spring reduces the long-distance displacement generated by the tremor process to a certain proportion of short-distance displacement through the geometric deformation scaling function of the lever, and at the same time con...

Abstract

The invention discloses a lever lateral mobile damping four-wheeler manned lunar rover folding system and belongs to the field of spaceflight. The system solves the problem that a four-wheeler is easily overturned integrally, difficultly climbs, runs into hollow surfaces, works cumbersomely, is high in energy consumption, low in adaptability and occupies a large space to hinder the implementation of exploration tasks and the like under the complicated geographical conditions on the surface of a star in the prior art. One side of a first rover body (1-1) is welded with two right-angled steel channels (6); the other side of the first rover body (1-1) is in folding connection with one side of a second rover body (1-2) through two middle connection folding mechanisms (8); the other side of the second rover body (1-2) is welding with two right-angled steel channels (6); the first rover body (1-1) is detachably connected with the second rover body (1-2) through a pair of rolling shaft pins (9) and pin slots (15); the lower end face of a bearing plate rover (1) is uniformly provided with four dual-wheel moving mechanisms. The system is used for a manned lunar rover.

Description

technical field [0001] The invention relates to a folding system for a four-wheel vehicle-mounted manned lunar vehicle with lever side movement and shock absorption, which belongs to the field of aerospace. Background technique [0002] This configuration is applied to the manned exploration vehicle in the rough terrain environment on the surface of the planet. It has strong ability to adapt to complex terrain, outstanding ability to overcome obstacles and slopes, good structural overall reliability, and convenient folding space-saving ability. The car body runs smoothly, which is convenient for light weight in working conditions. At present, the six-wheeled vehicle configuration is widely used. The six-wheeled vehicle configuration has many connecting components and kinematic pairs, and the overall reliability is poor, the control system is complicated, the obstacle surmounting ability is weak, and the energy consumption is large, so it is not suitable for use. However, th...
