Abstract

This disk brake device is provided with: a rotor (4) having a braking surface (4a); a caliper; an inner pad (43) and an outer pad positioned facing the braking surface (4a), and a braking operation mechanism which is made to perform a braking operation whereby both pads are pressed against the braking surface (4a). The braking operation mechanism is equipped with a base plate (35), a wedge plate (37) that holds the inner pad (43), a first movement conversion mechanism that moves the wedge plate (37) with respect to the base plate (35), parallel with the braking surface (4a) and in a direction perpendicular to the braking surface (4a) while sliding in the direction of rotation of the rotor (4), ___ an electric motor unit (24) that outputs driving force; and a second movement conversion mechanism that uses the rotational driving force of the electric motor unit (24) to slide the wedge plate (37) parallel to the braking surface (4a) and in the direction of rotation of the rotor (4).

Description

technical field [0001] The present invention relates to a disc brake device used in a vehicle or the like to generate a braking force using friction, and more particularly to a disc brake device configured to use an electric motor as a driving source for generating the braking force. Background technique [0002] Disc brake devices are widely used in vehicles and the like, and are configured to press a pad against a rotor rotating together with a wheel in response to a stepping operation performed on a brake pedal to generate frictional force, and thereby exert friction on the rotor. The rotation is braked. Conventionally known disc brake devices include a type that uses hydraulic force to actuate a piston to press a pad against a rotor and a type that uses compressed air instead of hydraulic force to actuate an operating lever. [0003] For example, in a disc brake device that actuates a piston using hydraulic pressure, such as a booster that amplifies the operating force ...
