BRAKING FORCE GENERATION DEVICE OF VEHICLE

摘要

A braking force generation device of a vehicle includes a rotary member, a frictional member, a pressing device, and a self-discharge type static charge eliminator provided on a surface of a particular member. The self-discharge type static charge eliminator changes air around the self-discharge type static charge eliminator into negative air ions, according to the quantity of positive charge carried by the particular member, and eliminate charge by causing the negative air ions to attract the positive charges of the particular member for neutralization, so as to reduce a quantity of charge of the particular member, and thereby reduce a quantity of charge of the lubricant.

1. A braking force generation device for a vehicle, the braking force generation device comprising:
a rotary member rotating about a rotational axis along with a wheel; a friction member being supported so as not to rotate about the rotational axis; a pressing device including a stationary member and a displacement member, the stationary member, having sliding portions, being supported by a knuckle, the displacement member being operable to slide relative to the stationary member, support the friction member and press the friction member against the rotary member, sliding portions of the stationary member and the displacement member being lubricated by a lubricant; and at least oneself-discharge type static charge eliminator being provided on a surface of a particular member, the particular member being at least one of the rotary member, the friction member, the stationary member and the displacement member, wherein the at least one self-discharge type static charge eliminator is an air-ion-exchange type self-discharge static charge eliminator, the air-ion-exchange type self-discharge static charge eliminator being configured to change air around the self-discharge type static charge eliminator into negative air ions, according to a quantity of positive charge carried by the particular member, and eliminate charge by causing the negative air ions to attract the positive charges of the particular member for neutralization, so as to reduce a quantity of charge of the particular member, and thereby reduce a quantity of charge of the lubricant.
