Abstract: PURPOSE: A self-boosting disk brake device is provided to prevent abnormal behavior due to the abrasion of a roller using self-boosting effect since a non-spherical gear is used in place of a wedge member and a roller. CONSTITUTION: A self-boosting disk brake device comprises first and second friction members(21,22), an actuator, a Non-Spherical gear(5) and a connecting unit. The first friction member is arranged on one side of a panel member which is moving. The second friction member faces the first friction member across the panel member on the other side of the panel member. The actuator transfers the first friction member in the moving direction of the panel member when a brake operates. A non-spherical rotating member rotates in a first direction if the first friction member moves in the moving direction of the panel member. If the non-spherical rotating member rotates in the first direction, the connecting unit comprises a first bracket, a second bracket and a connecting element(6). If the non-spherical rotating member rotates in the first direction, the connecting element connects the first bracket and the second bracket so that the first friction member becomes close to the second friction member.

Abstract: The present invention relates to an automobile engine control system and method for extending idling stop time which can extend the idling stop time by calculating an absolute time based on traveling information of a front vehicle, and inputting the calculated absolute speed to a speed transfer function to calculate a driver model and thus to control on/off of an engine. The engine control method includes the steps of providing the traveling information if an inter-vehicular distance is less than a preset threshold value; calculating the traveling information to calculate the absolute speed of the front vehicle; calculating the driver model which is a predicted absolute speed value of the subject vehicle based on the absolute speed; and turning on the engine of the subject vehicle if the predicted absolute speed value is equal to or more than the preset threshold value. Thereby, it is possible to reduce a load of the vehicle and provide the driver with the drive convenience.

Abstract: PURPOSE: A disc friction clutch apparatus using a magnetism strengthening principle is provided to enable a clutch to be connected only with weak. CONSTITUTION: A disc friction clutch apparatus using a magnetism strengthening principle comprises a driving friction disc(32), a driven friction disc(42), a pressing member(44) and an actuating unit. The driving friction disc is connected to a driving shaft and rotates by the driving shaft. The driven friction disc is connected to a driven shaft to enable axial movement with respect to the driven shaft. The driven friction disc receives the torque from the driving friction disc on the engaging position of a clutch and transfers it to the driven shaft. The pressing member is connected to the driven shaft to enable rotating movement and axial movement with respect to the driven shaft. The pressing member presses the driven friction disc to the driving friction disc on the engaging position of the clutch. The actuating unit rotates the pressing member, which is located on the released position of the clutch, in a first rotating direction. The actuating unit moves the driven friction disc in an axial direction and changes the pressing member to the engaging position of the clutch.
