Description

Elastic wheel with II-type rubber element

Technical Field

The invention belongs to the field of rail transit, and relates to an elastic wheel with a type II rubber element.

Background

With the development of science and technology, people's demand for daily transportation means is not only limited to convenience and rapidness, but also has higher demand for the comfort level of the transportation means.

Urban light rails are used as a convenient and quick travel mode, and are increasingly widely used in daily life of people, but the noise of light rail vehicles also influences the comfort level of people. Meanwhile, the wheel is disabled due to the polygonal corrugation effect generated by abrasion between the wheel rail and the wheel, and the elastic wheel is widely used in light rail vehicles as a means for reducing vibration and noise and improving corrugation.

The elastic wheel is added with the elastic element in the wheel hub and the wheel core to achieve the purposes of vibration reduction and noise reduction, but the elastic element adopted at present is mostly in a U shape or a V shape, so that the elastic element is not only complex to install, but also easily deviates in motion, and the wheel is caused to fail.

Disclosure of Invention

In view of the above, the invention provides an elastic wheel with a type ii rubber element, which not only can meet the performance of the wheel, but also greatly ensures the usability of the elastic element through the inner and outer rubber elements, and further enhances the anti-failure capability of the wheel.

In order to solve the problems in the prior art, the invention adopts the technical scheme that the wheel comprises a wheel hub, a wheel core, a pressure ring, a pressure block and a rubber element. The clamping ring is connected with the wheel core through the stud, the outer elastic element is arranged in a groove in the inner circumference of the wheel hub, and the inner rubber element is connected with the wheel core through the pressing block. A supporting pressing block is arranged between the two rubber elements, grooves are formed in the wheel core and the pressing ring, the rubber elements and the pressing block can be placed in the grooves, and relative movement of the rubber elements, the pressing block and the wheel core in wheel movement is eliminated. It is characterized in that the rubber element is composed of two layers of rubber blocks with I-shaped sections. The compression ring is connected with the wheel core through the stud and is provided with a groove to prevent relative movement of the elastic element. The boss on the inner circumference of the hub is in clearance fit with the wheel core.

Compared with the prior art, the invention has the following advantages:

1) the invention uses the rubber element with the section of I shape, and the relative movement among all the parts is further controlled by arranging the corresponding lug bosses and the corresponding grooves on the wheel hub, the wheel core and the pressure ring.

2) The invention adopts two layers of rubber elements, thereby further improving the elastic property. The middle of the two layers of rubber elements is separated by a rigid supporting pressing block, after one layer of rubber element fails, the other layer of rubber element can still bear load, and the other layer of rubber element and the supporting pressing block continue to form an elastic wheel to run. Until both layers of rubber elements fail, the entire wheel is converted to a rigid wheel for continued operation.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The embodiment provides an elastic wheel with II type rubber components, including wheel hub 1, wheel core 2, clamping ring 3, support briquetting 4 and 5,

rubber component

6 and 7, clamping ring 3 and wheel core 2 pass through stud and link to each other, form 9 recesses after connecting, have support briquetting 5 in every recess. The

rubber elements

6 and 7 are composed of a plurality of rubber blocks with I-shaped sections, a supporting pressing block 4 is arranged between two layers of rubber elements, and the outer layer rubber element 6 is arranged on a groove on the inner circumference of the hub 1.

The

rubber elements

6 and 7 are each composed of 9 identical annular arrangements of I-shaped rubber blocks. The outer layer can be arranged in a groove on the hub, the inner layer can be positioned in a groove of the hub base, and the pressing ring is provided with a groove corresponding to the hub so as to be positioned.

When the outer rubber element 6 fails, the hub 1 is matched with the supporting pressing block 4 to continuously transmit torque, and the hub 1 and the inner rubber element 7 continue to form an elastic wheel to move. When the inner layer elastic element 7 is also failed, the supporting

pressing blocks

4 and 5 are matched to continuously transmit torque, and the whole wheel is converted into a rigid wheel to continuously move.

The compression ring 3 and the wheel core 4 are connected through the double-end stud, and the double-end stud can be applied to the connecting position which is compact in structure and needs to adopt a blind hole. Therefore, the elastic wheel can be conveniently assembled and disassembled.

After the

elastic elements

6 and 7 are failed, any damaged layer can be replaced, and the cost can be greatly saved.

It should be understood that the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and that various modifications and alterations can be made therein by those skilled in the art without departing from the spirit of the present invention.
