Strut bar je ojačitev, obstajajo pa sprednji zgornji, sprednji spodnji in zadnji zgornji ter spodnji.

Zgornji spredaj, pride na koloteka:


Spodnji spredaj:


Zadaj zgoraj, pride med koloteka:


Zadaj spodaj:


Športni stabilizatorji, kar iščeš ti, pa se jim reče anti roll bar, oz. na kratko arb.

Zadaj:


Spredaj (slika sicer kaže da pridejo v amortizer, vendar pridejo s stabilizator štangicami pripeti na roke vozila):


Nisi povedal za kateri avto se gre.. pri nekaterih vozilih je Anti roll bar dobro menjat, pri nekaterih je standarni ok.. dosti vozil ga zadaj sploh nima, in ga nekateri dokupijo samo za zadaj. Za ojačitve pa je najbolj pogosta spredaj zgoraj, dosti pa jih ima zadnje čase tudi zadaj zgoraj (če vidiš kdaj slike, ko avto stoji s enim sprednjim kolesom na nižjem delu kot drugim, pa ima zadaj kolo v zraku..)

Strut Bars and Chassis Strengthening Technology

If you're serious about your car's handling performance, you will first be looking at lowering the suspension. In most cases, unless you're a complete petrolhead, this will be more than adequate. However, if you are a keen driver, you will be able to get far better handling out of your car by fitting a couple of other accessories to it. The first thing you should look at is a strut brace. When you corner, the whole car's chassis is twisting slightly. In the front (and perhaps at the back, but not so often) the suspension pillars will be moving relative to each other because there's no direct physical link between them. They are connected via the car body, which can flex depending on its stiffness. A strut brace bolts across the top of the engine to the tops of the two suspension posts and makes that direct physical contact. The result is that the whole front suspension setup becomes a lot more rigid and there will be virtually no movement relative to each side. In effect, you're adding the fourth side to the open box created by the subframe and the two suspension pillars.



Is there a need to have our vehicle chassis strengthened?

The chassis of the car is the part which experiences the most of the abuse from the driver. It is particularly due to the weight transfer of the vehicle body during fast cornering, hard braking or hard acceleration. In some instances, the weight transfer during cornering may cause one side of the vehicle to experience as much as 3 times more force than the other side of the vehicle, causing enormous chassis flex/ vehicle body deformity and twist, consequently causing tires to lose grip. Deformity and twisting of the vehicle chassis during cornering may cause negative handling traits such as understeering and oversteering.

What is understeering and oversteering?

UNDERSTEER :
*

Front wheels lose their traction and cause the car to go wide. Understeer can be corrected by stiffening the vehicle's rear chassis.

OVERSTEER :


*

Rear tires lose grip and causing the rear end of the vehicle slides out. Oversteer can be corrected by stiffening the vehicle's front chassis.

1.

As most modern cars go, car manufacturers employ the FF (Front engine, Front wheel drive) setup for improving driver and passenger safety. The natural behavior of an FF car is to have a slight understeer, due to its heavier front end. Understeer happens when the front wheels lose their traction and won't turn any sharper, even when the steering is being corrected to turn the car more. This will cause the car to go wide instead of following the line. Understeer can be corrected by stiffening the rear end of the vehicle by adding a Rear Strut Bar and a Rear Anti Roll Bar.
2.

Oversteer is when the rear tires lose grip and causing the rear end of the vehicle slides out of a corner. This phenomenon happens particularly to FR (Front engine, Rear wheel drive) or RR (Rear engine, Rear wheel drive) cars. Oversteer can be corrected by stiffening the front end of the vehicle by adding Front Strut Bars and Front Anti Roll Bars.

What is Chassis Flex?

With a strengthened chassis, the vehicle will react better to tuning changes. The improvement is particularly obvious over a hard suspension setting. The chassis is also able to cope better after the engine upgrades and Braking System upgrades. A strengthened chassis, by Chassis Strengthening Technology, will also protect the vehicle platform to allow it to last longer under hostile conditions, especially for monocoque vehicle platform.



There are various types of strut bars

FRONT STRUT BARS

Mounted at the front chassis for strengthening purposes. To eliminate all the suspension noise and more stability during acceleration, hard driving and braking ( simulating race track conditions ).

Every vehicle’s front chassis is different therefore designs and develops the front bars based on the actual conditions of the vehicle, repeatedly testing and proving to its perfection. High attention is taken during the design and development stage to ensure the chassis is able to withstand the load when a bar is being installed.

Ultra Racing is proud to bring to you the first of its kind in the country, the MULTI-POINT Front Strut Bar. The Front Strut Bar is installed to minimize the weight transfer of the vehicle body, therefore the vehicle will not loose traction easily during cornering.




REAR STRUT BAR & REAR UPPER BAR

Mounted at rear section of the car chassis (boot). Similar to the function of the front strut bar. The rear strut bar is use to support the rear section of the chassis, so that the force generated during hard braking and driving can be reduced.

The Rear Strut Bar is particularly useful for an FF vehicle. The Understeer behavior can be corrected by stiffening the rear chassis by installing a Rear Bar.

High attention is taken during the design and development stage to ensure the rear chassis is reinforced and strengthened in a proper way that it will not cause the vehicle body to undergo too much stress.

Rear Upper Bars is designed for vehicles with high roof and high CG (Centre of Gravity) such as MPV's, mini MPV's, SUV's and Hatch Backs.

Initially, Rear Upper Bar is invented specially for the 5 Doors Hatch Back cars. The 5 Door Hatch Back cars have weaker rear upper body due to their wide opening rear door. Under extensive investigation and actual road proving, it corrected the shortcoming of the vehicle’s swaying rear upper body.



SIDE FENDER BAR

Installed at the left and right side of the vehicle wheel arch or fender. Fender bars can give extra support and strength to the chassis especially during cornering.

As most of the vehicle’s front chassis over hanging is designated to carry the vertical loads from the front suspensions, it is vital that this part of the chassis is strong enough to take the bounce and rebound force of the suspension. Else, the effort of a good suspension will lose its meaning if the chassis absorbs all the forces from the suspension and not letting the suspension does what it suppose to do.

Therefore, these high quality 3-Point Fender Bars strengthen and reinforce these essential areas of your car and help maintain the suspension in position from all kind of vertical loads.

As a matter of fact, Fender Bars come as a standard feature on most of the high performance vehicles such as MITSUBISHI EVO and SUBARU WRX. Now, you can have the same feature on your car too!
Advantages of the fender bar:

*
Improve handling, stability at high speed and cornering, hence safer driving.
*
Provide a better braking and stopping performance.
*
Reduce NVH (Noise, Vibration and Harshness).
*
Increase stiffness of vehicle front chassis.




ANTI-ROLL BAR / SWAY BAR

Anti Roll Bars (also known as anti-sway bars, sway bars or lower tie bars) affect the handling of the car on the lower end of the suspension. Sway bars tie the lower suspension components together across the front or back, and affect a car's over steer and under steer. Sway bars will keep your car flat in turns instead of leaning over to one side. They distribute energy from the side of the car with all the force from the turn on it to the other side of the car, bringing the whole car down flat instead of leaning to one side. Of course the car will still lean some, but not as much. Sway bars provide better cornering especially at high speeds and work very well in conjunction with strut tower bars. However, they can have an adverse affect in off-road situations by leaving one tire completely off the ground.





LOWER ARM BAR

The Ultra Racing Lower Arm Bar is designed to reduce the flex of the vehicle chassis where it is connected by the Lower wishbone of the suspension system, thus to lessen the distortion of the vehicle lower suspension when it is under load, especially during hard cornering. It is installed at the lower mounting points between the left and right suspension and the vehicle chassis. Tremendously improving the stiffness at the area where the lower arm is connected to the vehicle chassis. The Ultra Racing Lower Arm Bar also keeps camber accurate during hard cornering.




ROOM BAR / SIDE FLOOR BAR

It is the bar linking both the B-Pillars within the passenger compartment. The effect of room bar is particularly obvious for a four-door sedan. This is because four-door sedan has a longer body than the hatch-back or coupe, the chassis is by nature weaker than the later two.

pusti stabilizatorje in rajši tršaj samo s fedrami. Če pa res hočeš menjat, se pa pozanimaj ali ima M podvozje pri 520i spredaj kaj debelejši stabilizator kot serijsko podvozje. Če ima, daj tistega gor ali pa od kakšne močnejše izvedenke.

Z stabilizatorji sem že skoraj diplomiral. med iskanjem tapravega sem se kar namučil. torej, kaj je vse pomebno pri stabilizatorju.
Kot prvo stabilizato mora biti testiran. To pomeni da ne sme bit samo testiran na stroju, ampak njegovo delovanje,zvijanje. to je zelo pomebno. ljudje mislijo da če daš gor čim večjega in trdega bo boljše. ne, na tak način uničiš avto. Kot že povedano stabilizatorji se zvijajo. To zvijanje mora biti primerno vozilu. V primeru da se stabilizator manj zvije kot karoserija oz. več, se zna zgodit da se zvije karoserija. Če se zvije karoserija seveda ni nič dobrega. ultra racing so mi bili zelo zanimi stabilizatorji, dokler jih nisem vprašal kakšen materjal uporabljajo za njih, kako jih testirajo itd. Ugotovil sem da oni jih samo po "občutku" naredijo. Torej, stran od njih.
Jaz imam civic in sem želel kupit zgronji zadnjega. Verjemite ali ne, nisem našel še primernega. Verjetno ga sploh ne bom dal gor, ker preprosto ne obstaja. Vsi so samo racing kateri pridejo v poštev samo na dirkališču kjer te ne briga kaj dosti za avto.
Vsekakor zraven stabilizatorja je pomebno tudi dobro podvozje. Brez tega ni nekega pametnega efekta.

@MRV: Kako pa zgleda "zgornji" zadnji stabilizator?

Verjetno je mislo strutbar

Metat strut bar/brace in pa stabilizator (anti roll bar) v isti koš ne moreš, ker imata povsem različni funkciji.

Vem

stabilizator zgornji zadnji kako to zgleda?

isti k*** stabilizator ali strut bar. so res 2 različni stvari vendar zelo podobni in v slovenščino niso tega ravno prevajali. lahko se vrže vse en koš in se jim reče "ojačitve".

kako izgleda zadnji zgornji? povezuje zadnja 2 amortizerja v prtljažniku. ena štanga počez

Nista isti stvari, pravtako ne opravljata enaki funkciji. Ojačitve niso še nobenemu avtomobilu škodile, edino "lahko" škodijo pri trku. Debelejši stabilizator pa lahko negativno vpliva na šasijo če je pretrd, vendar, hej ho, no risk, no gain. Tako ali tako so avtomobili samo punktirani in se školjka sama po sebi zvija že na serijskem podvozju.
Tukaj je debata o stabilizatorjih, in ne o strut brace-ih/bar-ih, kateri imajo funkcijo večanja togosti šasije.

Stabilizatorji so narejeni iz vzmetnega jekla, strut brace pa lahko iz navadnega "pleha".

Tak kot je drmo napisal. Stabilizatorji preprečujejo nagibanje karoserije in prenose teže medtem ko strutbar-i omejujejo zvijanje karoserije in ohranjajo kolesa v pravilni legi (camber caster etc...)
