However, the above-mentioned adjustable tail systems do not make full use of the adjustable space of the tail, so as to further adjust the braking and handling stability of the racing car
Nowadays, in many low-level formula competitions, such as the major racing cars in the student formula competition, the way of steering gear to drive the connecting rod is generally used to adjust the angle of attack of the tail flap. Although this method is simple in structure and easy to arrange, it is generally reliable. The stability is not high, and the driving torque of the steering gear is limited, resulting in slow response when driving at high speed, and the steering gear is easily damaged
And most of the current formula car tail fins have a single shape, so that the utilization rate of the tail in a limited space is not high

Embodiment Construction
[0029] The present invention will be further described below in conjunction with accompanying drawing.
[0030] Such as figure 1 As shown, the main body part of the tail system of the full-condition adaptive adjustable tail system of the formula racing car includes the tail end plate 6, the variable section fixed main wing 16, the middle fixed end plate 17, and two left and right flaps 8 and 9 with adjustable angle of attack. , and the air brake adjustment block 7 at the rear of the end plate; the variable cross-section fixed main wing is fixedly connected with the empennage end plate 6 through 16 bonding, and the aluminum alloy ribs are embedded on both sides of the flaps 8 and 9, and the middle part of the rib Open a hole and set the rotating shaft in the hole, and the rotating shafts on both sides are respectively mounted on the empennage end plate 6 and the middle fixed end plate 17; the air brake block 7 is connected with the empennage end plate 6 through the rotating sha...

The invention discloses a full working condition self-adaptive adjustable tail device and method for a formula racing car, comprising two left and right tail end plates, one fixed main wing, a middle fixed end plate, two left and right flaps with adjustable angle of attack, and two left and right flaps with adjustable angle of attack. Air brake stop on the rear of the plate. There are two sets of hydraulic drive mechanisms on the left and right sides, the first set is set on the end plates on both sides to drive the angle of attack of the flaps, and the second set is set on the end plates near the air brake block to drive the rear air brake. The moving plate opens and closes. Electro-hydraulic control system: hydraulic control part, including three-position four-way electromagnetic reversing valve, speed regulating valve, gear hydraulic pump, relief valve and flow control circuit composed of pressure reducing valve, throttle valve and one-way valve; The electronic control module is connected to the CAN bus to collect data from various sensors, judge the driving conditions and send different signals to the electromagnetic reversing valve to connect the hydraulic pump to the hydraulic cylinder, and drive the connecting rod and rocker arm through the hydraulic cylinder to drive the wings Turning changes flap angle of attack and air brake stops open and close.
Description
technical field [0001] The invention relates to the field of vehicle aerodynamic control, in particular to a rear wing device and method for formula racing cars. Background technique [0002] Most of the existing automatically adjustable tail systems of sports cars or racing cars have relatively single functions, and can only realize two working conditions of low resistance in a straight line and high lift in a curve according to two situations of driving in a curve and in a straight line. There are also some racing cars that can divide the cornering conditions of the adjustable tail into two kinds of conditions: sharp cornering with high angle of attack and slow cornering with small angle of attack according to the sharpness of the curve. But above-mentioned adjustable empennage system all does not make full use of the adjustable space of empennage, thereby further regulates the braking and handling stability performance of racing car. Nowadays, in many low-level formula c...
