WHEEL SUPPORT DEVICE FOR VEHICLE

摘要

A wheel support device for a vehicle includes a bearing that rotatably supports a wheel, and is lubricated by a lubricant, a bearing support member, and a self-discharge type charge eliminator provided on a surface of a particular member. The self-discharge type charge eliminator is configured to change air around the self-discharge type charge eliminator into negative air ions, and eliminate charge by causing the air ions to attract positive charges of the particular member for neutralization, so as to reduce the quantity of charge of the particular member, and thereby reduce the quantity of charge of the lubricant.

主权项

1. A wheel support device for a vehicle, the vehicle having a road surface and a body held electrically bye an insulation state, comprising:
a bearing rotatably supporting a wheel, and being lubricated by a lubricant; a bearing support member supporting the bearing; an accessory member connected to the bearing support member; and a self-discharge type charge eliminator being provided on a surface of a particular member, the particular member being at least one of the bearing, the bearing support member, and the accessory member, wherein the self-discharge type charge eliminator is an air-ion-exchange type self-discharge charge eliminator configured to change air around the self-discharge type charge eliminator into negative air ions, according to a quantity of positive charges carried by the particular member, and to eliminate a quantity of charge carried by the lubricant by causing the negative air ions to attract the positive charges carried by the particular member for neutralization, so as to reduce the quantity of charges carried by the particular member, and thereby reduce the quantity of charge carried by the lubricant.
