Problems solved by technology

[0003] However, the general wheeled wheel has a big limitation, that is, the size of the outer peripheral contour of the wheel is fixed, and the adaptability to ground fluctuations and obstacles is small. Moreover, in some occasions, the terrain is very complicated and there are various terrain obstacles. To complete the research tasks, the probe vehicles used in these occasions must not only have basic functions such as forward, backward, turning, climbing, picking up objects, sampling and turning over (turni

Embodiment Construction

[0016] The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0017] Such as figure 1 with figure 2 As shown, the wheel with variable wheel diameter in the present invention includes a wheel outer profile and a diameter reducing device for driving the deformation of the wheel outer profile, wherein the wheel outer profile is formed by cross-connecting several small blades 1 from end to end.

[0018] The reducing device comprises three bull gears 2, three eccentric connecting rods 6 fixedly connected with the bull gears, a pinion 3, a motor 4 and a shaft frame 5 fixing the central axis of the bull gear 2. One end of the eccentric connecting rod 6 is rotationally connected with the small blade 1 through a pin, and the other end is fixedly connected with the large gear 2 . The motor 4 is fixedly connected with the axle frame 5, and the output shaft of the motor 4 is fixedly connected with the...

Abstract

The invention discloses a vehicle wheel with a variable wheel diameter. The vehicle wheel comprises a vehicle wheel outer profile and a variable-diameter device used for driving the vehicle wheel outer profile to deform, wherein the vehicle wheel outer profile consists of a plurality of small blades which are connected crosswise with each other end to end; the variable-diameter device comprises an eccentric connecting rod of which one end is rotationally connected with the small blades, a bull gear which is fixedly connected with the eccentric connecting rod and a driving part used for driving the eccentric connecting rod and the bull gear to rotate around a central shaft. The vehicle wheel with the variable wheel diameter has the characteristic of telescopic outer profile, so the vehicle wheel can avoid barriers, enhances balancing capacity while running on a complicated ground surface, reduces accident rate and is easy to operate.

Description

technical field [0001] The present invention relates to a foldable wheel, more specifically, to a wheel with variable wheel diameter. Background technique [0002] At present, the wheels used for detection mission vehicles developed at home and abroad are all wheeled wheels. The movement of wheeled wheels is highly adaptable to the ground, and has the characteristics of reliable operation and convenient control. For example, the Nanorover miniature Mars rover developed by the Jet Propulsion Laboratory of the United States, and the Micro-5 planetary rover developed by the Japan Space Development Agency (NASDA), etc. [0003] However, the general wheeled wheel has a big limitation, that is, the size of the outer peripheral contour of the wheel is fixed, and the adaptability to ground fluctuations and obstacles is small. Moreover, in some occasions, the terrain is very complicated and there are various terrain obstacles. To complete the research tasks, the probe vehicles used ...
