Wheel surface element, particularly wheel cover for wheel of passenger car, comprises cover body with opening, cover flap hinged on one side of opening, and actuating element, which has lower curvature between its primary and secondary ends

摘要

#CMT# #/CMT# The wheel surface element (2) comprises a cover body (9) with an opening, a cover flap (3) hinged on one side of the opening, and an actuating element. One end of the actuating element is coupled with the cover body and another end of the actuating element is coupled with the cover flap. The actuating element has a lower curvature between its primary and secondary ends with certain primary temperature, where its secondary temperature is higher than the primary temperature. The actuating element has a bimetallic strip (5), an elastic element and a shortening element made of shape memory alloy. #CMT#USE : #/CMT# Wheel surface element, particularly a wheel cover for a wheel of a vehicle (Claimed), particularly passenger car. #CMT#ADVANTAGE : #/CMT# The actuating element has a lower curvature between its primary and secondary ends with certain primary temperature, where its secondary temperature is higher than the primary temperature, and thus improves ventilation of the brake device by opening the cover flap at high temperature and by closing the cover flap at low temperature while reducing the air resistance, and also ensures safety by preventing outward projection of the opened cover flap, and enables a simple and economical manufacturing of the wheel surface element. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of a wheel surface element. 2 : Wheel surface element 3 : Cover flap 5 : Bimetallic strip 6 : Fastening clip 9 : Cover body 13 : Ring.
