Mutli Link Suspension

1. A Presentation on AUTOMOBILE MULTILINK SUSPENSION SYSTEM By- Anand Kulshreshtha 1416440030 ME-3A

2. Suspension  is the system of tires, springs , shock absorbers and linkages that connects a  vehicle to its wheels and allows relative motion between the two. What is Suspension

3. In early 1665 the leather springs were used Then Elliptical Leaf Springs were came into with the rubber wheels in 1795 1919 Hydraulic shock absorber were used Multi Link Suspensions in 1960 MacPherson struts in 1970s Bose automative suspension in 2009 Hydraulic Cross link suspension in 2015 History of Suspensions

4. An Experiment with a car

5. Springs Shockers Struts Main Components of Suspension

6. • Guide motion of each wheel along (unique) vertical path relative to the vehicle body without significant change in camber. •Mobility (DOF) analysis is useful for checking for the appropriate number of degrees of freedom, Dof = 3(N – 1) – 2J – H Where N=number of links J=number of binary joints H=Higher Pair The mobility of suspension mechanisms

7. Mobility Of Suspensions

8. Dependent Suspension System Independent Suspension System Types Of Suspensions

9. Dependent Suspension  there is a rigid linkage between the two wheels of the same axle. A force acting on one wheel will effect the opposite wheel. For each motion of the wheel caused by road irregularities affects the coupled wheel as well. Some Types of Dependent Suspension Satchell link Panhard Rod Watt’s Linkage WOBLink Mumford linkage Leaf Springs Dependent Suspension System

10. This system means that the suspension is set-up in such a way that allows the wheel on the left and right side of the vehicle to move vertically independent up and down while driving on uneven surface. A force acting on the single wheel does not affect the other as there is no mechanical linkage present between the two hubs of the same vehicle. In most of the vehicle it is employed in front wheels.

11. A multi-link suspension is a type of vehicle suspension design typically used in independent suspensions, using three or more lateral arms , and one or more longitudinal arms. A wider definition considers any independent suspensions having three control links or more multi-link suspensions. These arms do not have to be of equal length , and may be angled away from their direction. Multi Link Suspension Honda Accord 5 link suspension

12. Problems for the driver in handling of the vehicle at Uneven Roads Poor response of Tyres during the bumps Extra space required by the suspensions Need Of Multi Link Suspension Toyota Auris Multi Link Suspension

13. The arms have to control steer. This needs a pair of arms longitudinally separated. The arms have to control camber, particularly the way that the camber changes as the wheel moves up (into bounce, or bump) and down into rebound or droop.

14. The arms have to react traction and braking loads, usually accomplished via a longitudinal link. They also have to control caster. Top View Rear View

15. Companies are working on cheap designs of Multi Link Suspensions Reduction in number of links without hindering performance Use of Magnetic Dampers Application in the racing applications Present Work and Research on Multi Link Suspension

16. Renault Duster AWD Audi A3 Cabriolet (2015) Audi RS Q3 Lamborghini LP70 Volkswagen Tiguan Latest Car Models on Multi Link Suspension system

17. Audi uses Z shaped Multi Link Suspension Practical Application while Using Multi link Suspension

18. Renault Duster AWD Model uses a Torsion Beam with the Multi Link suspension

19. The best Independent Suspension system The multi link is also advantageous for the designer who can alter one parameter in the suspension without influencing the entire assembly. It take less space in comparison to others It allows the suspension to flex more Best handling ,efficiency and comfort handling Advantages Of Multilink Suspensions

20. It is very Expensive Complex Design Difficult Manufacturing Need a check by Analysis Software's like AMD etc Disadvantages

21. Use of composite materials for better Stability The Computerized operated suspensions systems Use of Electromagnetic waves in the suspensions Predictive suspension System Future Prospects
