Vehicle Suspension Systems

Non-independent Front Suspension:

Solid Axle

A solid axle suspension system incorporates a solid column or shaft that covers from left to right in the automobile. A pivoting connection connects both the left and right ends of the shaft to the wheel spindle, allowing the spindle to change towards the left of right. The solid axle design may use tea leaf springs or coil suspension systems linked from the vehicle structure (frame) to the lateral sides of the solid axle beam, therefore allowing upward movement when road bumps are found. learn more here

Independent Front System Types:

Double Wishbone Design

Two times wishbone (and their by artificial means equivalent double A-arm design) incorporates some triangular parts or “wishbones”, one “wishbone” stacked vertical to the other. The medial (toward the midline of the vehicle) long end of each triangular part is mounted to the framework of the vehicle by using a pivoting connection. The horizontal (away from vehicle midline) pointed end of each triangular part is installed to either the higher or lower ball joint of the related tyre hub. The upper and lower ball joints allow the wheel to convert left or right. A spring/shock absorber assembly is typically installed between the vehicle structure and the lateral portion of the lower wishbone (A-arm), thus supporting the vehicle and damping bumps. The two times wishbone has been considered as the gold standard for rear wheel drive vehicles for many years. A standard double wishbone delay, pause uses a shorter higher wishbone compared to the lower, thus creating negative camber (tilting outward of the lower portion of the wheel) as the suspension rises during protrusions or turns. The not as long upper wishbone helps to keep the tire toned during cornering.

McPherson Swagger Design

A McPherson swagger suspension can be thought of as a variant of the double wishbone design. It borrows the a lower wishbone (A-arm) from the double wishbone design. The McPherson swagger omits the upper wishbone (A-arm) and instead uses a spring and impact absorber assembly (strut) installed between the lower horizontal wishbone (A-arm) and your vehicle structure. This strut is usually much better than a typical shock absorber used on the double wishbone design since it should prevent twisting of the low wishbone (A-arm) which would typically occur during stopping or acceleration. The features of the McPherson Strut design include simplicity, weight cost savings and reduced bulkiness. The reduction in bulkiness allows space for a drive shaft to the wheel heart, thus allowing for use on fwd cars.

Step-wise Suspension Systems:

Larger plane typically use a steerable type of linear delay, pause for their nose rims. This suspension is considered “linear” considering that the wheel movements in an aligned range upwards when a street bump is encountered. These types of aircraft suspensions can be considered a steerable variance of the oil/air type shock absorbers since both share common characteristics. Though historically a few old fashioned types of linear suspension systems have been attempted on motor vehicles, none have got the best discount thus far. Newer designs of linear suspension systems have incorporated electromagnetic power generators or remotely mounted spring suspensions (connected by cables) for weight suspension and dissipating.
