A drum brake apparatus includes a housing; a main braking unit installed on one part of the housing, and driven by a hydraulic pressure and pressing a shoe, during main braking; and a parking braking unit installed on the other part of the housing, and driven by an electromotive force of an actuator and pressing the shoe, during parking braking, the parking braking unit includes a bevel gear section disposed in the housing while having a structure of a bevel gear, and rotated in association with the actuator; and a rod section connected with the bevel gear section, and moved out of the housing in association with the bevel gear section and pressing the shoe.

Drum brake apparatus

An airbag device of a vehicle and a control method thereof. The airbag device of a vehicle includes a detection unit configured to detect collision information of a vehicle and seating state information of an occupant, an airbag unit including a plurality of airbag modules, each of the airbag modules being configured to be inflated from a contracted state as working gas is supplied and to be restored to the contracted state as the working gas is discharged, a valve unit configured to regulate the working gas supplied to the airbag unit, and a control unit configured to determine a hitting position based on the collision information and the seating state information, and to control the valve unit to supply the working gas to a target airbag module installed at the hitting position, thereby inflating the target airbag module.

Airbag device of vehicle and control method thereof

Disclosed is a caliper brake apparatus. The caliper brake apparatus includes: a housing that includes a piston capable of moving straight; a carrier that is combined with the housing and mounted on a vehicle such that a disc of the vehicle is positioned therein; a pair of pad plates that is brought in close contact with the disc by straight movement of the piston; and a pair of guides that couple the pad plates and the carrier to each other, in which the pad plates each may have a sliding groove at both sides and the guides each have elastic members that can slide along the sliding grooves. Accordingly, it is possible to ensure sufficient gaps between a disc of a vehicle and the pad plates when the pad plates are separated from the disc after being strongly pressed to the disc of a vehicle.
