Embodiment Construction

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

[0017] Such as Figure 1-4 As shown, the variable-diameter wheel includes a fixed disk 1, a rotary disk 2 and several spoke rod assemblies 3. The center of the fixed disk 1 is fixed with a rotating shaft 12 through a screw 14. The rotating disk 2 forms a rotational fit through the journal of the rotating shaft 12, and the rotating shaft 12 passes through the The turntable 2 and the shaft stop 13 are connected by mounting screws 15. The spoke rod assembly 3 is stacked and arranged between the fixed disk 1 and the turntable 2 along the circumferential direction. The spoke rod assembly 3 includes two oppositely stacked spoke rods 31, two spoke rods The head is connected together by bolts 32 and nuts 33, the bottom of the spoke rod is rotatably connected with the fixed plate 1 and the turntable 2 through miniature bearings 34, the head of the spoke rod is a wheel profile s...

Abstract

The invention discloses a variable-diameter wheel, which comprises a fixed disc, a rotary disc and several spoke rod assemblies. A rotating shaft is installed in the center of the fixed disc. The rod assembly is stacked between the fixed disk and the turntable, the spoke rod assembly includes two oppositely stacked spoke rods, the heads of the two spoke rods are detachably connected, and the bottom of the spoke rods are respectively rotatably connected to the fixed disk and the turntable, Wherein, the rotation of the turntable drives the rotation and contraction of the spoke rod assembly. The present invention uses the handwheel operation to expand and contract the variable-diameter wheels, making the process of expanding and contracting the variable-diameter wheels very easy and easy to operate, and adopts multi-stage ladder rods to solve the interference problem in the contracted state, so that the expansion and contraction ratio reaches 100%. 2.4, the structure is compact, the overall appearance is small and exquisite, and it is easy to carry.

Description

technical field [0001] The invention relates to a wheel, in particular to a variable-diameter wheel. Background technique [0002] At present, the wheels used for exploration vehicles developed at home and abroad are all wheeled wheels. The movement of wheeled wheels has strong adaptability to the ground and is easy to control. However, the general fixed-sized wheels have little adaptability to ground fluctuations and obstacles. For exploration vehicles working on complex terrain, the larger the wheels, the better the obstacle resistance, and the smaller the space occupied by the wheels, the better. [0003] At the same time, the biggest problem faced by folding bicycles or wheelchairs on the market is that the wheels cannot be folded, resulting in a large space occupied after folding. Most of the existing variable diameters are deployed by hydraulic cylinders or electric push rods, because their large volume and weight are inconvenient to carry outside, which limits their ...
