Problems solved by technology

The inventor believes that the rigidity and shape of this ordinary wheel are generally fixed and non-adjustable, and it is suitable for driving on a single road; and this ordinary wheel generally uses pneumatic tires, which may cause air leakage and tire blowout during driving. dangerous situation
[0003] With the increase in demand, many special vehicles that need to work in complex and changeable terrain conditions have appeared on the market. The above-mentioned special vehicles require that the wheels must be suitable for various road conditions and have the characteristics of safety and reliability. At this time, ordinary pneumatic wheels It has been unable to meet its work requirements. Specifically, the existing common wheels have the following disadvantages:
[0004] The wheel diameter and stiffness cannot be adjusted to adapt to different working conditions; the pneumatic tires of the wheels are easy to affect the normal driving of the vehicle after air leakage

Embodiment 1

[0035] Such as Figure 1-7 As shown, the present embodiment provides a wheel structure with adjustable wheel diameter, which includes two inner wheels coaxially arranged, the inner wheel is provided with a shaft hole, and the shaft hole is coaxially arranged with the inner wheel, and the two inner wheels There are many pairs of support members installed between the inner wheels, each pair of support members includes two support pieces with one end hinged to each other, one end of the two support pieces hinged to each other is set away from the inner wheel, and the other end is respectively hinged with the adjacent inner wheel.

[0036] The supports are arranged in sequence along the outer circumferential direction of the inner wheel, so that multiple pairs of supports enclose to form the outer wheel, that is, the outer wheel is formed by combining multiple pairs of supports. A linear telescopic mechanism is provided between the two inner wheels, and the linear telescopic mecha...

Embodiment 2

[0049] This embodiment provides a vehicle that utilizes the wheel structure with adjustable wheel diameter, including a rotating shaft, the rotating shaft is installed in the shaft hole, one of the inner wheels is fixedly connected to the rotating shaft, and the other inner wheel is slidingly connected to the rotating shaft , the rotation of the rotating shaft drives the synchronous rotation of the two inner wheels, and the movement of the linear telescopic mechanism can drive the inner wheel slidingly connected with the rotating shaft to translate along the rotating shaft to change the distance between the two inner wheels and change the outer wheel wheel diameter.

[0050] Working principle: When the car is driving at high speed on the expressway, the hydraulic device can be adjusted to increase the distance between the two wheels, increase the width of the wheels, and lower the overall height, so that the overall center of the vehicle is lowered. At this time, the vehicle ha...

Abstract

The invention relates to a wheel structure with adjustable wheel diameter and a vehicle, comprising two inner wheels coaxially arranged, the inner wheels are provided with shaft holes, the shaft holes are coaxially arranged with the inner wheels, and the two inner wheels There are many pairs of support members installed between them, each pair of support members includes two support pieces with one end hinged to each other, one end of the two support pieces hinged to each other is set away from the inner wheel, and the other end is respectively hinged with the adjacent inner wheel; the support The parts are arranged in sequence along the outer circumference of the inner wheel, so that many pairs of support members enclose the outer wheel; a linear telescopic mechanism is provided between the two inner wheels, and the linear telescopic mechanism can adjust the distance between the two inner wheels. In order to make the two supporting pieces in each pair of supporting parts rotate along the mutual hinge point, and change the distance between the hinge point and the axis of the inner wheel.

Description

technical field [0001] The invention belongs to the technical field of vehicles, and in particular relates to a wheel structure with adjustable wheel diameter and a vehicle. Background technique [0002] A wheel is a rotating component mounted on a wheel axle to bear a load. A normal wheel usually consists of a rim (rim), spokes and tires. The inventor believes that the rigidity and shape of this ordinary wheel are generally fixed and non-adjustable, and are suitable for driving on a single road; and this ordinary wheel generally uses pneumatic tires, which may cause air leakage and tire blowout during driving. dangerous situation. [0003] With the increase in demand, many special vehicles that need to work in complex and changeable terrain conditions have appeared on the market. The above-mentioned special vehicles require that the wheels must be suitable for various road conditions and have the characteristics of safety and reliability. At this time, ordinary pneumatic w...
