  • Meritor® Independent Front Suspension Drivetrain System
    MERITOR® INDEPENDENT FRONT SUSPENSION DRIVETRAIN SYSTEM Meritor’s state-of-the-art modular drivetrain system for all-wheel drive (AWD) commercial trucks features the Independent Front Suspension (IFS) module equipped with modern steering geometry and air disc brake technology, and a low-profile shift on-the-fly transfer case. The IFS, available in drive or non-drive options, is a part of Meritor’s field-proven and widely acclaimed ProTec™ ISAS® line of independent suspensions. This bolt-on, modular solution does not require modifications to existing frame rails and maintains vehicle ride height. FEATURES AND BENEFITS ■ Proven Independent Suspension Axle System technology – The ISAS product line has been fitted on high-mobility vehicles for over 20 years. The Independent Front Suspension system leverages decades of expertise in designing and manufacturing field-proven systems. ■ Bolt-on system – The Independent Front Suspension does not require modifications to frame rails ■ 5 to 12 inch ride height reduction – Improves vehicle roll stability versus best-in-class beam axle ■ Modular solution – Maintains the same ride height of a rear-wheel drive (RWD) truck ■ Lower center of gravity – Better vehicle maneuverability and stability for safe and confident handling ■ 60 percent reduction in cab and driver-absorbed power – Ride harshness improvements as well as reduction in unwanted steering feedback lead to less physical fatigue for the driver, and higher reliability of the cab ■ 2-times the wheel travel – The Independent Front Suspension provides

  • Suspension System Need of Suspension
    Suspension system Need of Suspension • Support the weight of the frame, body, engine, transmission, drive train, passengers, and cargo. • Provide a smooth, comfortable ride by allowing the wheels and tires to move up and down with minimum movement of the vehicle. • Work with the steering system to help keep the wheels in correct alignment. • Keep the tires in firm contact with the road, even after striking bumps or holes in the road. • Allow rapid cornering without extreme body roll (vehicle leans to one side). • Allow the front wheels to turn from side to side for steering. • Prevent excessive body squat (body tilts down in rear) when accelerating or carrying heavy loads. • Prevent excessive body dive (body tilts down in the front) when braking. 08-05-2020 2 Suspension system 08-05-2020 3 Types of suspensions • The type of suspension springs used in automobile are • Metal springs Laminated or leaf Coil Torison bar • Rubber springs • Pneumatic springs Commonly used are leaf springs and coil springs • Leaf springs are mostly used in dependent suspension system. • Coil springs and torsion bar are used in mostly in independent suspension system. • Coil springs can store about twice as much energy per unit volume compared to that of leaf spring. Thus for the same job coil springs need weight only about half that of leaf spring. • Leaf springs both cushion the shock and guide the cushioned motion. • Coil springs can serve the both provided sway bars are used along with. 08-05-2020 4 Suspension system as a two mass system 08-05-2020 5 Leaf Spring suspension • These springs are made by placing several flat strips one over the other.

  • Wheel Alignment Simplified
    The WHAT and WHY of Toe Caster - Camber Kingpin Inclination - Thrust Angle Steering Angle – Wheel setback WHEEL ALIGNMENT SIMPLIFIED Wheel alignment is often considered complicated and hard to understand In the days of the rigid chassis construction with solid axles, when tyres were poor and road speeds were low, wheel alignment was simply a matter of ensuring that the wheels rolled along the road in parallel paths. This was easily accomplished by means of using a toe gauge or simple tape measure. The steering wheel could then also simply be repositioned on the splines of the steering shaft. Camber and Caster was easily adjustable by means of shims. Today wheel alignment is of course more sophisticated as there are several angles to consider when doing wheel alignment on the modern vehicle with Independent suspension systems, good performing tyres and high road speeds. Below are the most common angles and their terminology and for the correction of wheel alignment and the diagnoses thereof, the understanding of the principals of these angles will become necessary. Doing the actual corrections of wheel alignment is a fairly simple task and in many instances it is easily accomplished by some mechanical adjustments. However Wheel Alignment diagnosis is not so straightforward and one will need to understand the interaction between the wheel alignment angles as well as the influence the various angles have on each other. In addition there are also external factors one will need to consider. Wheel Alignment Specifications are normally given in angular values of degrees and minutes A circle consists of 360 segments called DEGREES, symbolized by the indicator ° Each DEGREE again has 60 segments called MINUTES symbolized by the indicator ‘.
