Corrosion-resistant electric vehicle hub sealing and connecting mechanism

Abstract

The invention relates to the related technical field of electric vehicle components, and discloses a corrosion-resistant electric vehicle hub sealing and connecting mechanism which comprises a hub body, an axle hub and a shaft hole, the axle hub is connected with the hub body through spokes, an outer ring embedding groove is formed in the outer end face of the axle hub, the shaft hole is located in the center of the axle hub, a positioning bearing is installed in the shaft hole, the shaft hole is connected with a hub shaft through the positioning bearing, an inner ring embedding groove is formed in the inner end face of the axle hub, and external threads are formed in the portion, outside the shaft hole, of the hub shaft. According to the corrosion-resistant electric vehicle hub sealing and connecting mechanism , air in a sealed space is prevented from oxidizing the connecting part between the hub shaft and the axle hub, so that the anti-corrosion performance of the outer end face of the axle hub is effectively improved, the maintenance and use period of an electroplated anti-corrosion layer in the outer end face area of the axle hub is prolonged, related operators can conveniently monitor the vacuum pressure value of the closed space in real time, and the stability of matched installation between structures is guaranteed.

Description

technical field [0001] The invention relates to the related technical field of electric vehicle components, in particular to a corrosion-resistant electric wheel hub sealing connection mechanism. Background technique [0002] Electric vehicles, that is, electric drive vehicles, have another name called electric drive vehicles. Electric vehicles are divided into AC electric vehicles and DC electric vehicles. Generally speaking, the electric vehicle uses the battery as the energy source. Through the controller, the motor and other components, the electric energy is converted into mechanical energy movement to control the current and change the speed. The hub is an important part of the electric vehicle, and the hub is the inner part of the tire. The rotating part of the wheel core connected by the profile steel through the connecting shaft, that is, the metal part that supports the center of the tire and is mounted on the shaft, is also called a rim, a steel ring, a wheel, an...
