Though there are several other suspension types, the wishbone or double-wishbone to be exact is pretty popular and has been around for almost a century.

Tokyo, July 2, - Suspensions are designed to ensure vehicle stability under any circumstance associated with accelerating, cornering and braking. To properly assume this role and thus avoid any undesirable movement, suspension design needs to be sophisticated. As an uncontested leader in front wheel drive technology, Honda has acquired extensive know how in driving stability. We have been able to determine that further improvements in front wheel drive basic performance required special attention toward the rear suspension. Carrying less weight than the front wheels and having no role in power transmission, rear wheel movement needs to be much better controlled using a sophisticated rear suspension. Rear body movement also plays an important role in driving comfort. Honda was one of the first makers to adopt a strut type suspension layout in its mid-class vehicles.

A car's suspensions job is to maximize the friction between the tyres tires and the road surface, through its contact patch. To provide steering stability with good handling and to ensure the comfort of the passengers in road cars. While the aim of a car manufacturer will be a comfy ride for passengers, this will not reap the ultimate reward for the driver's car, this requires agile handling. If a road surface were perfectly flat and had no irregularities in it, then suspensions would not be required to a certain extent. But roads are far from flat, even freshly paved motorways highways have subtle imperfections that can interact with the wheels. It's these imperfections that apply forces to the wheels and suspension components and causes handling imbalances in compromised set ups. Suspension is also used to control the vehicles body weight, both sprung and unsprung mass. Through the corners, under braking and acceleration. If you had two identical car in terms of weight, engine power, aerodynamics and tyres. The suspension design and set-up will be the difference between which one would be most competitive. Suspension systems help to control the movement of the car's mass and load transfer rates and this has a direct effect on the ability of the tyres to work in optimum conditions. If one tyre is over loaded compared to another on the same axle, this will result in an handling imbalance. If this happens when braking, one front tyre could lock up for example, resulting in reduced braking efficiency. If one tyre is over loaded on the rear axle, this could result in wheel-spin on rear wheel drive cars , reducing acceleration capacity. If the outside tyre is overloaded when cornering, this could result in a reduction in cornering force and increases understeer or oversteer.

This reduces the pressure and structural loads which results in a more robust design.

In an All Terrain Vehicle ATV , the suspension system plays an essential role and contributes towards the isolation of heavy vibrations in a system. The primary function of the suspension system is to absorb the shocks coming constantly from the bumps and maintains comfortable contact between an ATV and road.

Do you want the short answer or the long one? It depends on your make and model. Want to discover more? Other suspension systems, like the MacPherson strut suspension, feature a single control arm which is sometimes known as a wishbone. This means that, technically, these single control arm suspension systems can also be considered a wishbone system. Since being first installed in cars over a century ago, double wishbone suspension has helped to improve driving comfort, even on the bumpiest roads. Double wishbone suspension allows each wheel to act and react independently from the others. The upper and lower control arms have ball joints on both ends to allow movement in multiple directions. Vertical movement is controlled through the shock absorber and coil spring which are mounted on the wishbones. Double wishbone suspension systems are common on high performance cars and sporty sedans.

Considered a gold standard for sports cars, what is double-wishbone suspension, and how does it work? In the broader scope of types of vehicle suspension systems , double-wishbone suspension is a type of independent suspension commonly associated with sports cars and largely assumed to be a gold standard in vehicle suspension. But what exactly is double wishbone suspension, how does it work, what are its benefits and drawbacks, and how does it differ from other types of independent suspension systems? There's a lot to unpack, but we want to get one thing out of the way up front - double wishbones are not the second coming, and while they can be an indicator of a vehicle's performance prowess, a car with them is not automatically the sweetest handling thing on the road. That said, it is often a preferred choice for high-performance vehicles due to its superior handling characteristics, as it provides precise control over wheel alignment, particularly during cornering and over uneven surfaces. The presence of double wishbones in a Mazda MX-5 Miata is one of the reasons its handling is lauded so much despite its affordable price, for example. The double-wishbone suspension system, also known as Short-Long Arm SLA suspension due to one wishbone being shorter than the other, is a form of independent suspension comprising, wait for it, two wishbone-shaped or Y-shaped control arms connected to the chassis on one end and the wheel knuckles on the other.

The lengths of wishbones are decided by the wheel track of the vehicle and the position of the strut on wishbone is obtained from the motion ratio decided. The double wishbone suspension system provides balanced stability under dynamic conditions. Siddhant Swaroop. It is possible to place it exactly where is required, even more so than a coil installation. More in-depth information is covered in Suspension Upgrades and Suspension Tuning sections. Viewed as an older suspension technology set up, trailing arm design does take up a lot of space in the rear chassis area compared to other modern systems. Vadapalli Chaitu. All five arms fit within the circumference of the wheel, allowing for increased cabin space and a larger trunk volume. Aerodynamic balance can be effected, with overall aerodynamic devices decreasing their angle of attack in extreme situations. The geometry of the suspension has been modelled in commercial software package Lotus Shark. IOSR Journals. Honda's Rear Suspension Design History. Last of the list is the now universal coil spring, which undoubted is the favoured choice of modern racing applications.

Though there are several other suspension types, the wishbone or double-wishbone to be exact is pretty popular and has been around for almost a century. A double-wishbone is an independent suspension design that can be found at the front, rear, or all four wheels.

Part of the Automobile series. Friction free, with a low centre of gravity possible, no wonder this has been the modern solution for both road and race applications in modern times. It is a more simple version of this one which uses only 1 arm. The geometry of the suspension has been modelled in commercial software package Lotus Shark. The paper discusses design procedure of a double wishbone suspension system for an all-terrain vehicle ATV. Low and controlled roll centre compared to some designs, but this not the best in the class. Uncategorized says:. This allows engineers to easily tune the kinematic of the set up to optimise wheel motion. Scrap Mechanic Store Page. First we need the base and some bearings for the lower arms Next add some risers and bearings to attach the upper arms. Pan-hard Rod. In road car applications, you could have a car with jackal and Hyde characteristics. The quality of the design was assured by performing FEA which portrayed deformation and equivalent stresses well within the desired range. Article Talk. David Eidelberg.
