With an independent rear suspension, the differential housing itself will only hold the ring gear and differential carrier. Turns, bumps in the road, and uneven surfaces will have less effect on driving. This eliminates the need for trailing arms and a panhard rod (AKA track bar). Independent Rear SuspensionIndependent rear suspension, or IRS, has been around on production cars for decades. Disadvantages of suspension: Heavier – of course, super-expensive, super-light suspension fork for example, might be lighter than a cheap, steel rigid one, but it will be significantly heavier than any decent quality rigid fork. Technical Features and Benefits. There are two types of independent rear suspensions typically found in passenger cars and light trucks. Functionally Independent Design. The diameter of the bar varies from make to make. Non independent suspension : advantages good for off road... by lee hikin There are a number of important advantages to the new Morrison Multilink IRS; all of which add up to optimum handling and long-term dependability. This project calls for re-designing the 2008 FSAE car, giving it an independent rear suspension with a rear differential to replace the solid rear axle set-up. It also makes it apparent why this setup is being used on modern cars. And, of course, how much you are willing to spend. In the following lines, we shall first find out what an independent suspension system means, and then discuss the advantages and disadvantages of the independent front suspension system. Damping is necessary to control the vibrations produced due to road shocks Example: Honda city 1.5 on rear wheel. Technical Features and Benefits. Computerized systems are more accurate than mechanical. Launching, in particular, can be dramatically improved with the use of a solid rear axle. When one tire crawls over a rock, the meat of the opposite maintains contact on the trail, creating a smoother ride over rough terrain. This translates to better all-around control over the vehicle, as the weight is under better management. If you have back problems, this style tends to be easier on the joints and bones. This connection with a live rear axle can cause comical dynamic characteristics in a car when compared to a more modern independent suspension setup… This system always gets ragged on by the judges for using a primative design that has many disadvantages from an independent rear. Suspension technology is revolutionised by electronics. With an independent rear suspension, the wheels are essentially held in place by the suspension, whereas with a solid axle, the axle housing works as a brace. ADVANTAGES ( INDEPENDENT REAR SUSPENSION) Lesser unsprung weight – improves ride , reduces tyre wear. It really is something that depends on the true intended use of the vehicle. An independent rear suspension doesn’t necessarily perform better than a well-designed solid-axle setup. When browsing through off-road capable SUVs and trucks, you’ve probably encountered vehicles that sport an independent rear suspension system. Post was not sent - check your email addresses! Does not take driving or braking thrust. The Art Morrison independent rear suspension can trace its design lineage to a number of the world’s most renowned exotic automobiles. The way the suspension is constructed is really simple and strong, acting as a linkage that holds the axle in position without the need for separate linkage. So, what gives? Furthermore, rear-wheel-drive vehicles with IRS systems can lose their driving power altogether. When discussing independent suspension, often the term “wishbone suspension” will come up because of the design of the upper and lower control arms. It works in very much the same way as your front suspension … Rear suspension system which allows the wheels to retain their correct camber no matter how much the suspension is deflected.

Independent Front Suspension System: Purpose of Suspension System: Due to a number of disadvantages of the beam or rigid axle front suspension, the manufacturers use an improvised version i.e. And why Ford have decided against implementing this. It takes up less of the vehicle's interior volume compared to coil springs. This project calls for re-designing the 2008 FSAE car, giving it an independent rear suspension with a rear differential to replace the solid rear axle set-up. A solid axle is much simpler and generally uses fewer parts, while the independent rear ‘axle’ is a bit more complex. “We often see solid-axle cars keeping up with, or even outrunning, their IRS-equipped competitors,” writes sports car magazine, Grassroots Motorsports. The impact is isolated to one wheel, not transferred to the whole vehicle through the axle. Non-independent suspensionThe structure is characterized by non-independent suspension system two wheels connected by an integral frame, wheels, together with the axle together by elastic suspension system suspended from the frame or body below. Constant velocity axles are used and have no housings covering them; they also feature joints to allow them to articulate. And with so many moving parts, it’s only a matter of time before some of them need repair, maintenance, or replacement. This means you’ll get an exceptionally smooth ride in a vehicle with an independent rear suspension system.
