| 发明名称 | Friction brake device | ||
| 摘要 | A friction brake device has a brake rotor which rotates around a rotation axis, brake pads as rotating friction members which rotate around an autorotation axis parallel to the rotation axis, rotational torque transmission devices which mutually transmit rotational torques between the brake rotor and the brake pads without depending on the friction force between the brake rotor and the brake pads, and pressing devices which press the brake pads against the brake rotor. The pressing devices press the brake pads against the brake rotor by way of non-rotating friction members which are supported so as not to rotate around the autorotation axis. | ||

| 主权项 | 1. A friction brake device comprising: a brake rotor which rotates around a rotation axis; a rotating friction member which rotates around an autorotation axis parallel to the rotation axis; a rotational torque transmission device which mutually transmits rotational torque between said brake rotor and said rotating friction member without depending on a friction force between said brake rotor and said rotating friction member; and a pressing device which presses said rotating friction member against said brake rotor, wherein said pressing device presses said rotating friction member against said brake rotor by way of a non-rotating friction member which is supported so as not to rotate around said autorotation axis, and said rotational torque transmission device includes gears which are formed on said brake rotor and said rotating friction member and mesh with each other. | ||
