The invention belongs to the technical field of vehicle accessories, and particularly relates to a wind resistance reducing active wheel windshield ring system which comprises a fender, a wind ring piece, a transmission ring and a driving mechanism. A plurality of sliding groove sets are formed in the upper edge of the fender, and each sliding groove set comprises two parallel sliding grooves. A plurality of air ring pieces are arranged on the inner side of the arc of the fender, and one air ring piece corresponds to one sliding groove set. The side part of each air ring sheet is provided with two sliding rails, and one sliding rail corresponds to one sliding chute; a plurality of inclined grooves are formed in the fender, each inclined groove corresponds to one air ring piece, each air ring piece is provided with a boss, and the bosses penetrate through the corresponding inclined grooves; a rack is arranged on the outer side arc of the transmission ring and meshed with a driving gear. According to the invention, an actively-controlled wheel baffle wind ring structure is adopted, and the wind resistance coefficient of the whole vehicle is dynamically optimized according to requirements.
本发明属于车辆配件技术领域,尤其是一种降风阻主动车轮挡风环系统,包括翼子板、风环片、传动环、驱动机构;翼子板上沿边缘设有若干滑槽组,滑槽组包含两个相互平行的滑槽;翼子板的圆弧内侧设有若干风环片,一个风环片对应一个滑槽组;每个风环片侧部设有两个滑轨,一个滑轨对应一个滑槽;翼子板上设有若干斜槽,一个斜槽对应一个风环片,每个风环片上设有一个凸台,凸台贯穿于对应的斜槽;传动环的外侧圆弧上具有齿条,驱动齿轮与齿条啮合。本发明采用主动控制的车轮档风环结构,根据需求动态优化整车风阻系数。
