Intelligent maintenance type crossed shaft universal joint

Abstract

The invention relates to an automotive transmission part of the transport vehicle technique, in particular to an intelligent maintenance type crossed shaft universal joint. The intelligent maintenance type crossed shaft universal joint comprises a crossed shaft, bearing sleeves, framework oil seals and roller pins, wherein the bearing sleeves, the framework oil seals and the roller pins are arranged on shaft heads of the crossed shaft. Through holes where lubricating oil is poured are formed in the crossed shaft. Wireless wafer sensor assemblies are further arranged on the end faces of the shaft heads. By the adoption of the intelligent maintenance type crossed shaft universal joint, the working states of the shaft heads of the crossed shaft universal joint can be detected in real time, and the detected condition is sent to a receiver arranged on an instrument panel of a vehicle; and in this way, once the shaft heads of the crossed shaft universal joint break down, the receiver arranged on the instrument panel of the vehicle can send out a corresponding signal to remind a driver to pay attention to universal joint maintenance, and accordingly the problem that traffic accidents are caused by the failure of the universal joint can be solved to the greatest extent.

Description

technical field [0001] The invention relates to an automobile transmission component of the transport vehicle technology, in particular to a cross shaft universal joint technology. Background technique [0002] The universal joint is a very important part in the transmission system of the automobile chassis and the steering system of the automobile, which acts as a "fuse". The cross shaft head of the universal joint can be designed as a solid body, or as a hollow body with a through hole, in which the lubricating grease can be stored in the counterbore or through hole of the shaft head to ensure the smoothness of the cross universal joint. Work normally and stably for a long time. [0003] For example, the application number 201320735280.1 of "an automobile universal joint assembly" discloses an automobile universal joint, which "comprises a bell-shaped shell, and a drive shaft is fixedly connected to the end face of one end of the bell-shaped shell. There is also a groove...
