specific Embodiment approach 1

[0009] Specific implementation mode one: combine figure 1 and figure 2 Describe this embodiment, the suspension mechanism of this embodiment includes four wheels, four steering devices, cross bar 9, longitudinal bar 10 and chassis 11; The four wheels are arranged in a rhombus shape and are located on the four vertices of the rhombus, The four wheels are respectively the first wheel 1, the second wheel 2, the third wheel 3 and the fourth wheel 4, the first wheel 1 corresponds to the third wheel 3, and the second wheel 2 corresponds to the fourth wheel 4 , the four steering devices are respectively the first steering device 5, the second steering device 6, the third steering device 7 and the fourth steering device 8; Above, the two ends of the longitudinal rod 10 are fixedly connected to the first housing 5-4 of the first steering device 5 and the third housing 7-4 of the third steering device 7 respectively, and the first housing of the first steering device 5 The third con...

specific Embodiment approach 2

[0010] Specific implementation mode two: combination figure 1 To describe this embodiment, the hinge point 12 between the longitudinal bar 10 and the chassis 11 in this embodiment is located directly above the hinge point 13 between the cross bar 9 and the chassis 11 . With such arrangement, the body of the probe car has better balance. Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0011] Specific implementation mode three: combination figure 1 This embodiment will be described. In this embodiment, the center of each wheel is the same distance from the center of the four-wheel probe vehicle. With such a setting, the probe car has isotropy. Other compositions and connections are the same as those in Embodiment 1 or 2.

Abstract

The invention discloses a shuttle-type rocker arm suspension mechanism for a four-wheel detection vehicle, which relates to a suspension mechanism for a four-wheel detection vehicle, and aims at the problems of a moving system of a passive rocker arm type rhombic four-wheel moon vehicle, namely coupling influence of terrain where a front wheel, a left wheel and a right wheel are positioned to thepose of a vehicle body, poor stability of the vehicle body, and limited moving direction. A longitudinal rod is positioned right above a first wheel and a third wheel, two ends of the longitudinal rod are fixedly connected with a first steering device and a third steering device which are hinged with the wheel shafts of the first wheel and the third wheel respectively, two ends of a transverse rod are positioned right above a second wheel and a fourth wheel and positioned below the longitudinal rod, the two ends of the transverse rod are fixedly connected with a second steering device and a fourth steering device which are hinged with the wheel shafts of the second wheel and the fourth wheel respectively, and the transverse rod and the longitudinal rod are hinged with a chassis respectively. The shuttle-type rocker arm suspension mechanism has isotropy characteristics, eliminates coupling influence of the terrain where each wheel is positioned to the pose of the vehicle body, has goodstability of the vehicle body, and can be used for a planet probe vehicle, an unmanned probe vehicle under severe environment and a superior toy car.

Description

technical field [0001] The invention relates to a suspension mechanism of a four-wheel probe vehicle. Background technique [0002] Exploration vehicles used on planetary surfaces or other harsh environments are required to have strong terrain adaptability, flexible steering ability, better obstacle avoidance ability, stable body posture, and compact structure, low energy consumption, and light weight. At present, the most widely used probe vehicle is the six-wheel probe vehicle. The reason is that the traditional ground two-axle four-wheel vehicle has poor terrain adaptability and poor obstacle-crossing performance. However, the four-wheel vehicle has a compact structure, low energy consumption, and simple control. In order to enable the four-wheeled vehicle to complete complex detection tasks, it is necessary to configure a suitable suspension mechanism for it. [0003] The invention patent application with the publication number CN 101214783A and the publication date of ...
