Description
Technical field
The empennage that the utility model relates to be applied on electronic equation motorcycle race.
Background technique
Nineteen sixty-eight, empennage appear on the competition field F1 for the first time, and with regard to this, Ferrari has led current aerodynamics revolution,
But the effect of empennage is not known in most of racing car at that time.And now empennage has become in racing car highly important one
Point, purpose is exactly that enough lower pressure is provided to racing car, and the lower pressure that current F1 racing car empennage provides accounts for about pressure under vehicle
30% to 35%.Empennage makes racing car in the process of running at high speed to the lower pressure that racing car provides to increase the friction with ground
In can possess more excellent performance.Racing car traveling need on the way, between tire and ground it is good contact, avoid beat
It is sliding, power is sufficiently conducted on tire.In running at high speed, racing car can generate biggish lift, lead to tire
It is insufficient with the adhesive force on ground, phenomena such as being also easy to produce skidding.The lower most important application of pressure is exactly that match is reduced when excessively curved
The phenomenon that vehicle skids, turns on one's side, allows racing car to have more good handling on bend.But on straight way, empennage
Brought lower pressure, will increase resistance suffered by racing car, make racing car stall, in play, when racing car speed per hour reaches 120km, just
It will cause 10% to 20% stall.And adjustable empennage can efficiently solve this problem.On straight way, it can be laid flat
Empennage reduces suffered lower pressure；When excessively curved, increase tail angle, generates enough lower pressure.
