1 1 Suspension Getting there in comfort

2 2

3 3 Suspension system perform 6 basic functions: 1. Maintain correct vehicle ride height 2. Reduce the effect of shock forces 3. Maintain correct wheel alignment 4. Support vehicle weight 5. Keep the tires in contact with the road 6. Control the vehicle's direction of travel

4 4 Front Suspension Dependent Independent

5 5 Dependent Front Suspension Dependent front suspension uses a solid axle. Uses one steel or aluminum beam extending the width of the vehicle. The beam is held in place by leaf springs. solid axle is only used on heavy trucks, and off-road vehicles

6 6 Independent Front Suspension Developed in the 1930's to improve vehicle ride control and riding comfort wheels to respond individually to road conditions sprung weight is reduced, creating a smoother ride. Twin I-Beam, Type 1 Coil Spring, Type 2 Coil Spring, Torsion Bar, Double Wishbone,

7 7 Twin I-Beam similar to the solid axle improves ride and handling load carrying ability used on pickups, vans and four-wheel drive vehicles.

8 8 Type 1 Coil Spring 2 upper control arms 2 lower control arms 2 steering knuckles 2 spindles 2 upper ball joints 2 lower ball joints bushings coil springs Shock Absorbers short-arm/long-arm, or the parallel arm design

9 9 Type 2 Coil Spring coil spring is mounted on the upper control arm top of the spring is attached to the frame. upper ball joint receives the weight of the vehicle and the force of the coil spring makes it the load carrier

10 10 Torsion Bar no coil or leaf springs supports the vehicle weight and absorbs the road shock performs the same function as a coil spring: supports the vehicle's weight

11 11 Double Wishbone type of strut suspension space saving benefits of a strut of the parallel arm suspension more aerodynamic hoodline portion of the strut forms a wishbone shape does not rotate when the wheels turn
