Abstract
A friction brake device has a brake rotor including a disk part and a subsidiary rotor spaced apart from each other along a rotation axis and a cylindrical part integrally connecting their outer peripheral portions, brake pads which are rotatably supported around an autorotation axis parallel to the rotation axis between the disk part and the subsidiary rotor by a stationary member, rotational torque transmission devices which mutually transmit rotational torques between the brake rotor and the brake pads, and pressing devices which are supported between the disk part and the subsidiary rotor by the stationary member and press the brake pads against the disk part and the subsidiary rotor.
Claims11
A friction brake device comprising:
- a brake rotor which includes first and second disk parts spaced apart along a rotation axis and extending around said rotation axis over the entire circumference and a connection part integrally connecting the outer peripheral portions of said first and second disk parts;
- first and second rotating friction members which are supported between said first and second disk parts by a stationary member so that said rotating friction members can rotate about associated autorotation axes parallel to said rotation axis;
- first and second rotational torque transmission mechanisms which mutually transmit rotational torques between said brake rotor and said first and second rotating friction members without depending on the friction forces between said brake rotor and said first and second rotating friction members;
- and
- first and second pressing devices which are supported between said first and second disk parts by said stationary member and press said first and second rotating friction members against first and second mutually opposed friction surfaces of said first and second disk parts, respectively.
