CONSTITUTION: A flapping type flight vehicle comprises a hub(10), a first wing unit(21), a second wing unit(22), and a driving unit. The hub is installed in the flight vehicle. The first wing unit is rotatably and vertically connected around a rotary shaft(11) which is horizontal to the hub. The first wing unit comprises two wings(21a,21b) extended to opposite directions around the hub. The second wing unit is vertically and rotatably connected around the rotary shaft which is horizontal to the hub. The second wing unit comprises two wings(22a,22b) extended to the opposite directions around the hub. The first and second wing units simultaneously reciprocate in the opposite direction by the driving unit.

PURPOSE: An electro actuating wedge brake apparatus for a vehicle and a controlling method of the same are provided to improve the accurate of a braking operation by preventing the generation of non-linearity behavior in a wedge driving unit. CONSTITUTION: A wedge brake apparatus includes a driving wedge(110), a counter wedge(120), a wedge column(140), a nut bracket(160), a needle guide(170). One surface of the driving wedge is inclined. The counter wedge is opposite to the driving wedge. One surface of the counter wedge is inclined. The wedge column is installed to the driving wedge and pushes the driving wedge. The nut bracket is installed to the external surface of a ball screw(150) and transfers driving force to the wedge column. The ball screw is rotated by the motor. The need guide connects the wedge column and the nut bracket.
Abstract:
A steer by wire system and a control method using the same are provided to give the least counter force to a steering wheel when a counter force motor is broken while a spring is installed in the steering wheel by employing two control units for each part and motors for an actuator. A steer by wire system comprises a steering wheel(110), three steering wheel angle sensors(120), steering wheel control units(130), a counter force motor (140), and a spring(160). The steering angle sensors are mounted on the steering wheel to detect rotation angle of the steering wheel. The steering wheel control unit compares measured values of each steering angle sensor to detect errors of each steering angle sensor, compares the measured values of the steering angle sensors without errors to calculate difference caused by elasticity of the steering wheels, and measures torque applied to the steering wheel. The counter force motor gives rotation counter force to the steering wheel according to the measured torque value. The spring, which is attached to the steering wheel, provides a minimum counter force to the steering wheel when the counter force motor is out of order. The number of the steering wheel control units is at least two so that one controls the steering wheel when the other is broken.
