Abstract

The invention discloses a wear detection device for hub motor tires, which comprises a box body, the box body is provided with a rectangular groove, and the long sides of both sides of the groove are provided with The opening is provided with a bearing fastener; the groove is provided with a driving device with the driving end facing upwards, and a flat plate is connected to the driving end of the driving device, and a pressure sensor is embedded on the surface of the flat plate. The pressure sensor is connected with an oscilloscope arranged on the surface of the box body. The invention proposes a wear detection device for in-wheel motor tires to solve the problem in the prior art that it is difficult to objectively judge the local wear degree of electric vehicle tires, and to achieve the purpose of accurately and objectively judging the wear degree of in-wheel motor tires.

Description

technical field [0001] The invention relates to the field of electric vehicle accessories, in particular to a wear detection device for hub motor tires. Background technique [0002] The wheel hub is also called the rim, the wheel, and the tire bell. It is a barrel-shaped, center-mounted metal part that supports the tire on the inner profile of the tire. There are many types of hubs according to diameter, width, molding method and material. People customarily refer to the wheel hub and the rubber carcass sheathed outside the wheel hub as tires. Electric bicycles, electric scooters, and even electric vehicles all belong to the category of electric vehicles. With the advancement of hub motor technology, electric vehicles have also been greatly promoted and developed. However, for tires made with in-wheel motor technology, the degree of local wear can only be judged by the naked eye, and the judgment results are not accurate and objective enough.
