Gear-driven axial modulating mechanism for rotating shafts realizing a controllable pitch propeller/fan
This invention employs a generic axial modulating mechanism to manipulate the pitch of the blades of a fan or propeller; conceptually, this is a threaded bolt and nut where the threaded bolt would be analogous to a rotating shaft, with an acme thread (i.e. the “rotor thread”) on its exterior, and the nut would be analogous to the axial modulator of this teaching. The “nut,” or axial modulator, is further spun above and beyond the rotation in the rotating bolt or rotating shaft. The axial motion of the axial modulator is then deployed to do useful work i.e. manipulate the pitch of the blades of a fan or propeller. This invention is a continuation in part of a previous variant disclosed where the means of modulating the axial modulator was magnetic. The variation introduced in this teaching instead achieves the modulation using a gear-driven arrangement. |

Brake system and method for operating a brake system
An electrohydraulic brake system, comprising a brake master cylinder. A pressure generating device for actuating wheel brakes and an additional brake actuator may both be activated electronically. In a normal mode of operation, an open- and closed-loop control unit detects a braking demand based on the actuation of a brake pedal by the driver and activates the pressure generating device to build up braking torque at the wheel brakes. If the pressure generating device is not activated, the driver gains direct access to the wheel brakes and the control unit activates the additional brake actuator to build up braking torque. In the fallback mode, when a predetermined pedal travel threshold value is reached, the control loop activates the additional brake actuator to build up braking torque. In the event of a succession of brake pedal actuations by the driver, the pedal travel threshold value is increased at least once. |
