Description
Technical field
The present invention relates to a kind of Anti-side-turning device more particularly to a kind of preventing vehicle rollover pro-active intervention devices.
Background technique
With the increase of car ownership, people increasingly pay attention to the security performance of automobile.Vehicle is being travelled or was being transported
Cheng Zhong, when turning excessive velocities, it is anxious spin to, load cargo unbalance loading etc. due to, may cause vehicle rollover, daily life
In this accident happen occasionally, once occur vehicle rollover, life and property to people can all cause to seriously threaten.
Preventing vehicle rollover at present is a big project of domestic and international Vehicle Industry.The factor for causing vehicle to turn on one's side is very
More, not only centrifugal force caused by vehicle turning causes this factor of vehicle rollover, such as the contained cargo of vehicle to be biased to
Side, side impacts are excessive, Cross Wind Force is excessive, inclination spends the reasons such as big and all may cause vehicle rollover.Therefore
Need to study a kind of device for preventing vehicle rollover.
At the initial stage that vehicle is turned on one's side, extraneous intervening force simultaneously does not have to that vehicle rollover can be effectively prevent very much greatly.Now
The anti-rollover technology that vehicle uses is mainly the brake force used at left and right sides of electronic control system control wheel, when wheel or so
When the brake force of two sides is unequal, flywheel moment can be generated, although certain anti-rollover effect can be played, also will affect
The steering characteristic of vehicle influences bigger especially when running at high speed.It is big that this device not only controls difficulty, but also price is higher,
Because of price problem, do not popularized in commercial vehicle at present, and the main vehicle that commercial vehicle is exactly turned on one's side.

Right height sensor is separately mounted to left stringer, on right vertical beam, for the height change of real-time detection chassis assembly, and by signal
Real-time delivery is to controller；Controller judges left and right vehicle wheel loaded-up condition according to control strategy, if there is trend of turning on one's side, controller
Servo valve events are controlled, if the oriented left side-turning trend of vehicle, the left extension bar of servo valve control pneumatic cylinder is acted, pneumatic cylinder
Left extension bar acts and then drives left support arm to stretching on the outside of chassis assembly, and then left tire is made to generate support force；, whereas if
The oriented right side-overturn trend of vehicle, the right extension bar movement of servo valve control pneumatic cylinder, the right extension bar of pneumatic cylinder acts and then band
Right support arm is moved to stretching on the outside of chassis assembly, and then right wheel tire is made to generate support force.
The interstitial hole of the left guide support, right guide support is rectangular opening.
The left support arm, right support arm section are rectangle, in rectangular dimension and left guide support, right guide support
Between pore size be adapted.
The beneficial effects of the present invention are:
A kind of preventing vehicle rollover pro-active intervention device, can be on the basis of not changing primary car structure, by increasing Auxiliary support
Tire improves the suspension support forces of left and right vehicle wheel two sides, has large wheel away from can be effectively improved in conjunction with auxiliary support wheel mould
Support effect plays the role of preventing vehicle rollover.The present invention compared with the existing technology, has compact-sized simple, installation just
Benefit, fast response time, cheap advantage.
