If you're wondering what it is between the body and asphalt, we bring you the answer in the following lines. Suspension systems are the mechanisms and elements with the task of all forces and moments watch dogs that occur between the wheels and the ground when moving vehicles are transferred to the frame or chassis with the maximum cushioning load, and ensuring the stability of the vehicle, especially when moving around curves. Movement of vehicles on the carrier causes oscillations watch dogs vehicles and masses that are in or on the vehicle. What are the speed of movement and vehicle weight is greater the greater the variability. watch dogs Due to the acceleration of mass oscillations caused may interrupt the contact point with the ground. Due to the break point of contact with the ground is lost steering and braking and can lead to loss of vehicle stability. In a well-executed suspension system dynamic forces to a lesser extent transferred to the passenger compartment of the vehicle and passengers, so the ride will not cause fatigue and discomfort by passengers while driving. The suspension system is a complex system that generally consists watch dogs of four separate systems: a mechanism for keeping the wheels, watch dogs elastic supports, damping elements and stabilizers. The task of the system for keeping the wheels is to provide as favorable relative movement of the wheel relative watch dogs to the frame or body of the vehicle. Elements of keeping the wheels also need to provide transfer horizontal watch dogs forces and moments from the point on the frame or body of the vehicle. Systems for keeping the wheels will be explained in more detail in a future issue. The task of the elastic supports is to transfer vertical forces on the frame or body of the vehicle and to ensure watch dogs the highest possible mitigation during the transfer of vertical forces, ie. to reduce shock loads to the fullest extent. Elastic supports need to protect the structure of the vehicle and passengers from unpleasant vertical displacement and rotation around the vertical axis horizontal ii vehicles. Elastic supports are made in several ways: leaf, spiral or torsion springs, watch dogs rubber or rubber-metal elastic elements, hydraulic, pneumatic or hydropneumatic springs.
Leaf spring leaf spring are elastic elements that are under force bent. They consist of a longitudinal spring (leaf) rectangular or elliptical shapes that are stacked on each other. The sheets are secured to the leaf spring is not moved the uzužno relative to one another, and also to provide that the sheets watch dogs would pomerali laterally relative to one another. The main advantage of leaf spring in comparison to other solutions that allow not only perform the function of elastic support, but they can transmit axial forces (driving and braking force) to the body or frame of the vehicle. Because of the mutual friction between the individual sheets, leafy spring also carries out the function of the damping element. Leaf spring are relatively inexpensive, yet reliable and robust solution. Today, the combination of a rigid axle and leaf springs has can meet only a small number of passenger vehicles, watch dogs mainly cars sport-delivery type (SUV). For commercial vehicles, this solution is still extensive. The solution reliance with coil springs shown in Fig. Coil springs Coil springs can receive power only in the axial direction, which is why they are not used for receiving watch dogs of lateral and longitudinal loads. Therefore, structures with coil springs always have longitudinal and transverse persistent ties that bind one end of the lower support watch dogs spring and the other part of the body. In this way, persistent leverage on themselves longitudinal and transverse loads while receiving coil springs watch dogs vertical watch dogs loads. The suspension system with coil springs shown in Fig. Benefits of coil springs in relation to the leaf spring suspensions are lower weight, longer service life, the absence of friction, simple structure, lower price and simpler maintenance. Bugs have already mentioned the inability to carry longitudinal forces and the absence of damping effects. These deficiencies resulted in a greater degree of complexity of the system with coil springs system with leaf spring because the system of elastic supports must add a separate damping systems and leadership. Coil springs are made of steel wire of circular cross section and are commonly used as a basic elastic support.
Torsion springs are also used as basic elastic support. They can be placed transversely or longitudinally with respect to the vehicle, but always in the horizontal plane. Torsion springs are elastic watch dogs elements made from genuine rods of circular cross section, are composed of one or more pieces in the shape of the beam. Disadvantages torsion springs are great length that require the need for a special mechanism for managing and inability damping. Rubber feet rubber feet are used for different purposes and in different dimensions for vehicles. Rubber has high characteristic exhibited oscillations damping and vibration, light weight, simple construction and acceptable service life. Rubber mounts are made in combination with plastic and me
