An electric actuator pushes the piston (11a) out towards the rotor. The electric actuator comprises a reduction gear (10a), a ball reduction gear (19), and a feed screw device (12a). A compression coil spring (43) applies a pre-load on each ball (24) that ...

A brake system comprising a body assembly comprising an outboard side (24), an inboard side (26), a bridge (10) extending between and connecting the inboard side and the outboard side, and two or more piston assemblies (13) located entirely on the outboard...

A control device for an electric parking brake controls a motor for driving a friction member of the electric parking brake. The control device includes a processing unit which starts the motor in order to drive the friction member to a direction for placi...

There is provided a drum brake type electric parking brake apparatus includes an electric actuator unit (5), a backing plate (2) and a knuckle (1). The electric actuator unit includes an electric motor (19) and a decelerator (20), and expands a gap between...

Provided is a bleeder plug which can be produced without a cutting operation in a production process, wherein problems in bleeding air, caused due to adhesion, do not occur. A bleeder plug 10 is provided with a bleeder body 30 having a nipple portion 12 an...

A disc brake apparatus with an electric parking mechanism includes an electric motor, a worm reduction gear and a thrust generation mechanism. A worm wheel of this worm reduction gear is supported on part of a rotational member which makes up the thrust ge...

The error of a sensor in motion capture system is corrected. An acceleration sensor determines the direction of gravity(G1) in a still initial state. The direction G1 will never change always if a drift dose not occur. However, actually if an object to whi...
