Embodiment 1

[0032] Such as Figure 1-7 As shown, the present embodiment provides a wheel structure with adjustable width and rigidity, including two inner wheels coaxially arranged (that is, the first inner wheel 1 and the second inner wheel 2 in the figure) and the same inner wheel as the inner wheel. The outer wheel 4 provided by the shaft is provided with a shaft hole in the inner wheel, and the shaft hole and the inner wheel are arranged coaxially;

[0033] The inner wheel and the outer wheel 4 are connected by a plurality of spokes 5, the two ends of the spokes 5 are respectively hinged with the inner wheel and the outer wheel 4, and the spokes 5 are sequentially arranged along the circumferential direction of the inner wheel, and the spokes 5 are Arc-shaped plate structure, the middle part of the spoke 5 protrudes toward the direction away from the inner wheel;

[0034] A linear telescopic mechanism is provided between the two inner wheels, and the linear telescopic mechanism can a...

Embodiment 2

[0042]This embodiment provides a vehicle that utilizes the wheel structure with adjustable width and stiffness, including a wheel shaft, the shaft is installed in the shaft hole, one of the inner wheels is fixedly connected to the shaft, and the other inner wheel is connected to the shaft Sliding connection, the rotation of the rotating shaft drives the synchronous rotation of the two inner wheels, the movement of the linear telescopic mechanism can drive the inner wheel slidingly connected with the rotating shaft to move in translation along the rotating shaft to change the distance between the two inner wheels, and Change the curvature of spoke 5. The vehicle includes a chassis, and the rotating shaft is supported by the chassis.

[0043] Working principle: When the vehicle is running on a flat road, in order to improve the fuel efficiency of the vehicle, the hydraulic cylinder assembly 3 can be adjusted so that the working distance between the first inner wheel 1 and the se...

Abstract

The invention relates to a wheel structure and a vehicle with adjustable width and rigidity, comprising two inner wheels coaxially arranged, the inner wheels are provided with shaft holes, and the shaft holes are coaxially arranged with the inner wheels; The outer wheel is coaxially arranged, the wheel diameter of the outer wheel is larger than that of the inner wheel, and the two inner wheels are respectively arranged on both sides of the outer wheel; the inner wheel and the outer wheel are connected by a plurality of spokes, and the two ends of the spokes are respectively connected with The inner wheel and the outer wheel are hinged, and the spokes are arranged sequentially along the circumferential direction of the inner wheel. The spokes are arc-shaped plate structures, and the middle part of the spokes protrudes toward the direction away from the inner wheel; a linear telescopic mechanism is arranged between the two inner wheels , the linear telescopic mechanism can adjust the distance between the two inner wheels, and the spokes can change their own bending degree in the process of moving with the inner wheels, so as to change their own stiffness and wheel width.

Description

technical field [0001] The invention belongs to the technical field of vehicles, and in particular relates to a wheel structure and a vehicle with adjustable width and rigidity. Background technique [0002] The wheel is one of the important components of the vehicle. Its main function is to support the weight of the vehicle body, transmit the torque of traction and braking, and ensure the adhesion between the wheel and the road surface. Ordinary wheels usually use pneumatic tires, which are filled with compressed air into elastic bags to ease the vibration and impact during movement, but pneumatic tires are often suitable for driving on relatively flat single road conditions, and ordinary pneumatic tires still exist The safety hazard of air leakage and blowout. [0003] At the same time, the inventor has learned that, when driving on relatively flat roads, reducing the width of the tires is conducive to reducing the resistance of the wheels when driving, which is convenien...
