20160059911 | SPOILER DEVICE FOR VEHICLE - A spoiler device for a vehicle includes a spoiler, a support mechanism supporting the spoiler, the support mechanism adjusting the spoiler to be positioned at a deployed position where the spoiler protrudes from an outer surface of the vehicle, the support mechanism adjusting the spoiler to be positioned at a retracted position where the spoiler is retracted within a housing recessed portion, the housing recessed portion being formed at the outer surface of the vehicle, a fixing member fixing the spoiler to the support mechanism, and a first tubular member and a second tubular member into which the fixing member is inserted, the first tubular member being provided with a first threaded portion at a first circumferential surface, the second tubular member being provided with a second threaded portion at a second circumferential surface, the first threaded portion and the second threaded portion being threadedly engaged with each other. | 03-03-2016 |
20160129951 | ADJUSTABLE SPOILER FOR VEHICLE AND METHOD FOR CONTROLLING THE SAME - An adjustable spoiler for a vehicle includes a pressure sensor sensing a pressure applied to an upper side of a spoiler and generating a current signal in proportion to the pressure. An electronic control unit (ECU) is configured to control an angle of a spoiler according to the current signal from the pressure sensor. The spoiler is mounted on the upper side of a vehicle body | 05-12-2016 |
20160137236 | APPARATUS FOR IMPROVING AERODYNAMIC CHARACTERISTICS OF VEHICLE - An apparatus for improving the aerodynamic characteristics of a vehicle includes a first vane configured to be rotatable on a wheel guard. An actuator is configured to provide the first vane with rotational force so as to rotate the first vane. A controller is configured to receive vehicle speed information and steering angle information of a steering wheel, and to control the operation of the actuator. | 05-19-2016 |
20160159412 | POWERED DEPLOYABLE SPOILER ASSEMBLY FOR MOTOR VEHICLES - A powered deployable spoiler assembly includes a support member adapted for mounting to a motor vehicle and a spoiler panel disposed in a recessed segment of the support member. A pair of power-operated drive units interconnect the spoiler panel to the support member and are operable to move the spoiler panel between a non-deployed position, a first deployed position to provide aerodynamic assistance at a first vehicle speed, and a second deployed position to provide augmented aerodynamic assistance at a second higher vehicle speed. Each drive unit defines a guide slot and includes a stanchion fixed to the spoiler panel and a follower assembly fixed to the stanchion and disposed for movement within the guide slot. Electric motors are coupled to rotary-to-linear conversion mechanisms for converting rotation into translation of the follower assemblies to control movement of the spoiler panel. | 06-09-2016 |
