Description
Technical field
The present invention relates to a kind of formula car, especially relate to a kind of Panhard rod of formula car.
Background technology
Panhard rod is a kind of auxiliary elastic element in automotive suspension.Its effect prevents from vehicle body from excessive transverse direction occurring when turning to roll, and makes vehicle body keep balance as far as possible.Object reduces the horizontal inclination degree of automobile and improves ride comfort.Panhard rod is the torsion bar spring made with spring steel, the horizontal front-end and back-end at automobile.The middle part of shaft, with stabilizer bar bushing and vehicle frame hinged, the two ends of bar are separately fixed on the suspension of left and right.When vehicle body only makes perpendicular movement, both sides Suspension Deformation is identical, and Panhard rod is inoperative.When automobile turning, body roll, both sides suspension is beated inconsistent, and outboard axle can press to stabilizer rod, and stabilizer rod will be distorted, and the elastic force of shaft can stop wheel lift, thus makes vehicle body keep balance as far as possible, plays laterally stable effect.
But, for formula car, because its motion is extremely fierce, bend is many, and sharply turning is many, and the requirement for Panhard rod is more much higher than general-utility car, and, in same racing track, the turn radius of bend alters a great deal, concerning Panhard rod, because its rigidity can not adjust change immediately, operator just needs the speed of a motor vehicle change focused on very much on different bend, to prevent it from turning on one's side, has considerable influence to racing car achievement.Therefore, if racing car can adjust the rigidity of Panhard rod immediately according to the change of bend, great raising can be produced to racing car achievement.
Summary of the invention
The rigidity of the formula car Panhard rod that the present invention mainly solves existing for prior art can not regulate, need the speed of a motor vehicle change focused on very much on different bend, turn on one's side to prevent it, racing car achievement is had to the technical matters of considerable influence, a kind of Panhard rod that can carry out instant stiffness equivalent in vehicle travel process is provided.

As preferably, described driver train comprises the slide block that the pull bar described in is connected, and slide block is connected with a piston crank mechanism, and piston crank mechanism is with the stepping motor of self-locking to be connected with one, and the control circuit of this stepping motor is connected with vehicle control center.Vehicle control center (thermoacoustic prime engine device) judges the turning amplitude of driving according to the rotational angle of the speed of a motor vehicle and bearing circle, carries out the turning amplitude according to this calculating, the rotational angle of control step motor.
According to above-mentioned different preferred versions, the invention provides following two kinds of control methods:
One, the method for the rigidity of Non-follow control Panhard rod, it comprises following process:
1, operator regulates manual regulation driving lever according to condition of road surface, make pull bar move to the correct position of rocking arm, Panhard rod has suitable initial stiffness, now, vehicle is when carrying out turning driving more by a small margin, and the rigidity of Panhard rod can reach requirement;
2, when vehicle carries out larger turning motion, operator is manual regulation driving lever again, drives pull bar to move backward, reduces the effective length of rocking arm;
3, when vehicle completes larger turning motion, operator is manual regulation driving lever again, drives pull bar to move forward, increases the effective length of rocking arm.
Two, automatically control the method for the rigidity of Panhard rod, it comprises following process:
1, in an initial condition, pull bar is in the appropriate location of rocking arm, makes the rigidity of transverse shifting bar be suitable for vehicle and completes turning motion more by a small margin;
2, vehicle control center will carry out the size of the width of turning motion according to the rotation amplitude of bearing circle and speed of a motor vehicle calculating vehicle, the motion of the stepping motor described in system controls according to this result of calculation, correct position is moved to make pull bar, thus reach the real-time control of the rigidity to Panhard rod, the turning amplitude calculated is larger, pull bar moves more backward, otherwise then pull bar more moves forward.
The beneficial effect brought of the present invention is, the rigidity solving the formula car Panhard rod existing for prior art can not regulate, need the speed of a motor vehicle change focused on very much on different bend, turn on one's side to prevent it, racing car achievement is had to the technical matters of considerable influence, achieve a kind of Panhard rod and the control method thereof that can carry out instant stiffness equivalent in vehicle travel process.
