Suspension

The term "suspension", we understand how to connect the wheels to the frame or vehicle body. The main function of the wheel suspension is to allow relative movement in relation to body or frame.

Suspension understand how to connect wheels to the body or vehicle frame. They often used the term "remedy" is not accurate, because the axle is made up of several functional units: among other things suspension, then saving wheels, suspension, brakes, or control or power train. Suspension bikes solve kinematic motion due to the vehicle wheels . Suspension allows relative vertical movement of wheel due to chassis or frame. This move is needed in terms of suspension. Suspension also to some extent eliminate unwanted wheel movement (especially the lateral shift and tilt wheel), the so-called leadership wheel.

Suspension carries the vertical load (vehicle load), the longitudinal force (driving and braking forces), the lateral force (centrifugal force) and moments of longitudinal forces from the roadway into the body and vice versa. There are many options and technical suspension solutions. Proper suspension has the greatest credit for the safety and driving comfort.

Types of suspension
Suspension divided into dependent and independent suspension. Dependent suspension, the solid axle , is the oldest way, suspension, wheels are stored in the common beam. Their relative position is unchanged. Solid axles are structurally simpler and cheaper. However, they have a large proportion of unsprung masses and undermining safety. Today, mainly used as the rear axle trucks.

solid axle and independent suspension

The suspension is independent all round hung on the body separately, virtually independently of the wheel opposite. Such a solution allows a substantial reduction in unsprung weight materials. The actuator is driven axle (axle and differential) mounted on the body.

Currently, these types are mainly used independent suspension:

PN (Front Axle)
▪ axle MacPherson (telescopic strut and lower arm triangle)
▪ Keystone correction (a pair of triangular cross-arms)

ZN (Rear Axle)
▪ shuttle axle angular (triangular shoulders oblique axis of oscillation)
▪ crank axle (longitudinal axis transverse to the arm swinging)
▪ torsion crank axle (axle coupled)
▪ De Dion (a combination of shuttle and solid axles)
