Adaptive deformable rear wings of racing car

Abstract

The invention provides adaptive deformable rear wings of a racing car, and belongs to the field of an automotive composite electromechanical system. Each adaptive deformable rear wing comprise a base, a plurality of deformation control drivers and surface skin, wherein, the surface skin is coated outside the deformation control drivers to form a rear wing main body; the base is arranged at the tail part of the racing car and is used for supporting the rear wing main body; each deformation control driver comprises drive joints, a shape memory alloy wire, a control module and an elastic element; and each deformation control driver is of a chain structure, the adjacent drive joints are movably chained together through a chained knuckle pin, the upper ends of the adjacent drive joints are connected together through the shape memory alloy wire, the lower ends of the adjacent drive joints are connected together through the elastic element, and the shape memory alloy wire is connected with the control module. The adaptive deformable rear wings provided by the invention have the beneficial effects that the wings generate greater downward force during the acceleration and brake process so as to obtain faster speed; during the high-speed running process, the wings can keep smaller resistance through shape adjustment so as to obtain higher speed; and the deformation control drivers are designed according to characteristics of shape memory alloy so as to simplify a drive mechanism.

Description

technical field [0001] The invention relates to a self-adaptive deformable racing wing, in particular to an adaptive deformable wing using a shape memory alloy as a deformation control driver, and belongs to the field of automobile electromechanical composite systems. Background technique [0002] As the aerodynamic part of the racing car, the fixed wind wing is used to generate additional downforce, increase the adhesion of the tire to the ground, and improve the acceleration, braking and handling performance of the racing car. However, under different vehicle speed conditions, there are also different requirements for the fixed airfoil itself. Due to the different shapes of the fixed airfoils, the downforce and drag produced are also different. In the process of acceleration and braking, it is hoped that the fixed wind wing has greater downforce to obtain more acceleration (deceleration) speed, and in the process of high-speed driving, it is hoped that the fixed wind wing...
