Description
Technical field
The invention belongs to vehicle suspension technical fields, and in particular to a kind of transverse direction of FSAE racing cars roll stiffness fast tunable
Stabiliser bar assembly and its adjusting method.
Background technology
The effect of FSAE racing car stabilizer bar is to adjust racing car suspension roll stiffness, when on the one hand reduction racing car is excessively curved
Body roll, on the other hand optimize racing car steering characteristic, quickly enter conducive to racing car it is curved and go out it is curved, improve games results.It adjusts
The demand of racing car suspension roll stiffness is explained as follows, and due to the error of racecar design, processing, assembling etc., racing car assembling is completed
Afterwards, suspension roll stiffness and racing car steering characteristic cannot reach optimum state, and different events is to racing car suspension
The requirement of roll stiffness and steering characteristic is different, it is therefore necessary to stabilizer bar assembly be made to have rigidity fast tunable
Function.
106853753 A of Chinese invention patent application publication No. CN disclose the horizontal stroke that rigidity is adjusted in a kind of FSAE racing cars
To stabilization rod mechanism, which realizes stiffness tuning by mobile row stabiliser bar, is swung when improving current stiffness tuning
Pull rod, the problem of leading to pull rod unbalance stress.But the lateral stability linkage has the following problems：（1）Bearing block volume is excessive,
Quality is excessive,（2）Single bearing seat is fixed using double bolts, and guide groove utilization rate is low, so as to increase the length of main board and quality,
（3）Single bearing seat is fixed using double nut, and dismounting process is more, and adjusting is less efficient,（4）Two side shaft holders can be on main board
It slides, when installation can not ensure the concentricity of two side shaft holders.
Summer shakes clever based on influence [J] agricultural equipment and vehicle of the ADAMS analysis stabilizer bar to FSAE suspension properties
Engineering, 2017,55 (6):25-28. analyzes influence of the stabilizer bar to racing car suspension property, the results showed that stabilizer bar
The control stability for travelling racing car is adjusted to play an important role.But the design of specific stabilizer bar regulating mechanism is not directed to,
Fail to solve the above problems.
Invention content
For above-mentioned regulating mechanism there are the defects of, the purpose of the present invention is to provide a kind of FSAE racing cars roll stiffness is fast
The adjustable stabilizer bar assembly of speed and its adjusting method, providing pull rod, slightly substantially mobile phase is tied with torsion-bar spring for swing
It closes, small step-length adjusts the adjusting method being combined with the adjusting of big step-length, substantially increases the utilization rate of lifting eye seat guide groove, drops significantly
