Damping wheel

Abstract

The invention relates to a damping wheel. Bearings, a gear, inner sliding block pressing parts and annular hinges are fixedly installed in key grooves of a connecting shaft through fixing keys, and one bearing, one inner sliding block pressing part and one annular hinge are sequentially arranged on one side of the gear. Outer wheel bodies are fixed to the two ends of the connecting shaft, and outer wheel rubber sleeves the outer walls of the outer wheel bodies. Tension springs are arranged between the outer wheel bodies and the corresponding annular hinges, and two short rods are arranged on the two sides of each inner wheel cushion block respectively. One end of each short rod is connected with the corresponding inner wheel cushion block through a rotating shaft, the other end of each short rod is connected with a long rod, the crossed parts of the two long rods are connected through a rotating shaft, one end of each long rod is connected with the corresponding outer wheel body through a screw, and the other end of each long rod is connected with the corresponding annular hinge through a connecting piece. According to the damping wheel, axial changes can be converted into radial changes through umbrella stands, and the advantage of a large radial changing amount is achieved; wheel bodies and dampers are combined and directly manufactured into the damping wheel, the damping wheel has a good mechanical property, and the diameter of the wheel can be changed along with the size of heavy objects so as to change assisting force.

Description

Technical field [0001] The invention relates to the field of shock-absorbing equipment, and in particular to a shock-absorbing wheel. Background technique [0002] When passing uneven roads or pits, the wheels will have a certain impact with the pits on the road. This impact must be avoided for the driver, and it is fatal to the car body, so this impact must be removed. The easiest way to reduce the impact is to directly use the suspension connection between the spring and the axle, which is also the most used on ordinary tricycles. Although such a design can save a lot of costs, it can indeed produce a certain effect, but it is only realized with a simple spring after all. When the spring is compressed and suddenly released, the spring itself will also produce a certain impact force. Although this impact force is much smaller than the force that compresses the spring, it is still fatal to the car body structure. In addition, the body structure above the spring will cause the s...

Problems solved by technology

Such a structure is very practical and does not require too much space for installation. However, since the elastic element is directly added in the radial direction of the shaft, the strength of the elastic element is high, and at the same time, a large force acting on the shaft will also shorten the life of the shaft. be affected
